Worf – son of Mogh, of the Klingon House of Martok, of the Human family Rozhenko; mate to K'Ehleyr, father to Alexander Rozhenko, and husband to Jadzia Dax; Starfleet officer and soldier of the Empire; bane of the House of Duras and slayer of Gowron; Federation ambassador to Qo'noS – was one of the most influential Klingons of the latter half of the 24th century.
Worf was born in 2340 on the Klingon homeworld, Qo'noS as the son of Mogh, patriarch of one of the Klingon Empire's Great Houses. When Worf was five years old, his father took him and his mother to live on the Khitomer colony. (TNG: "Sins of the Father") There, Mogh took Worf on a ritual hunt, along with a garrison warrior, L'Kor. Worf had not yet reached the Age of Inclusion, and was barely able to hold a bat'leth. During the hunt, Worf was mauled by a beast, leaving behind a scar and memory he kept throughout his life. (TNG: "Birthright, Part I")
In 2346, the Klingon Empire and the Romulan Star Empire were officially allied, but a conspiracy between the Romulans and the House of Duras left the Empire open to betrayal. Romulan forces attacked the Khitomer colony, killing nearly all the 4,000 Klingon colonists, including Worf's parents. (TNG: "Sins of the Father", "The Neutral Zone")
The colony's distress call was answered by the Federation starship USS Intrepid. An Intrepid chief petty officer, Sergey Rozhenko, found Worf buried in the rubble. Sergey took Worf to his homestead on the farming colony of Gault. He and his wife, Helena, raised the Klingon child alongside their own son, Nikolai. (TNG: "The Neutral Zone", "Heart of Glory", "Family", "Homeward"; DS9: "Change of Heart")
As the sole Klingon in a small farm culture, Worf had some difficulty adapting to his new circumstances, though years later Helena would describe her son as bright and highly spirited as a boy. Soon after his arrival on Gault, the seven-year-old bloodied the noses of five teenage boys, whom Worf deemed "disrespectful". In 2353, at thirteen years of age, Worf led his school's soccer team to the championships, where, in an attempt to score, he collided with another player, Mikel. The impact of Klingon ridges against a Human skull snapped Mikel's neck, and the boy died the next day. This lesson in Human frailties made a huge impact on Worf's nascent character. His self-control, interpreted by some as a denial of his Klingon heritage, was a large factor in setting his time apart from others of his species for much of his life. (TNG: "Family", "New Ground"; DS9: "Let He Who Is Without Sin...")
Coming of Age
At fifteen years of age, Worf voyaged to Qo'noS, where he stayed with cousins of the House of Mogh in 2355. Here he made the formal declaration of his intent to become a warrior and performed the Rite of Ascension. During the ceremony, Worf was presented with a well-forged knife, a gift from a Klingon who had known Mogh. Seeing the Great Domes of Qo'noS made him feel at home, but his kin rejected his marked Human taint. (TNG: "The Icarus Factor", "Rightful Heir"; DS9: "The Sword of Kahless")
Worf fasted for three days before undertaking the Rite of MajQa. After six days of meditation in the volcanic Caves of No'Mat, the legendary Klingon warrior Kahless the Unforgettable appeared to Worf in a vision and prophesied that Worf would do something that no other Klingon had ever done before. (TNG: "Birthright, Part I"; DS9: "The Sword of Kahless")
Service aboard the USS Enterprise-D
In 2364, Lieutenant junior grade Worf was assigned as a command division bridge officer on the USS Enterprise (NCC-1701-D), under the command of Captain Jean-Luc Picard (see Friendships: Jean-Luc Picard). Worf spent most of his first year on the Enterprise-D as a relief officer for the conn and other bridge stations. (TNG: "Encounter at Farpoint")
Worf was permitted a variation from the Starfleet uniform dress code, and wore a Klingon warrior's sash, sometimes called a baldric by Humans, over his regular duty uniform. Worf's quarters were on Deck 7, in Section 25 Baker until 2370, when he moved to Deck 2, Room 2713. (TNG: "Rightful Heir", "Phantasms")
Following the death of Natasha Yar at the hands of the Armus entity, Worf became acting security chief. In 2365, Worf transferred to the operations division and officially became the Enterprise-D's chief tactical officer and security chief. He was promoted to the rank of full Lieutenant in 2366. After seven years of service aboard the starship, Worf rose in rank to lieutenant commander in 2371. (TNG: "Skin of Evil", "The Child", "Evolution"; Star Trek Generations)
During these years of service, Worf's record was marred by a single reprimand, earned when he killed Duras in an honor duel after the latter had Worf's mate K'Ehleyr killed. Killing Duras directly affected the ascension of a new Klingon Chancellor after the death of K'mpec. (TNG: "Reunion")
Worf and his security team were the first Starfleet officers in over two centuries to engage Borg drones in combat when two boarded his ship. Worf, along with Commander William T. Riker and Lieutenant Commander Data were the first officers to infiltrate a Borg cube, gathering the first real clues about the true nature of the new threat. (TNG: "Q Who")
He played a significant role in repelling the Borg invasion of the Federation in 2366. When the Enterprise-D engaged the Borg cube, he was unable to prevent the abduction of Picard when drones appeared on the bridge. On Riker's orders, Worf and Data boarded the cube, and were able to retrieve Picard, allowing Dr. Crusher to restore their captain's Humanity. It was one of the most dangerous missions of his career, but six years later he would liken the exploits of his companions to the sagas of ancient warriors. (TNG: "The Best of Both Worlds", "The Best of Both Worlds, Part II"; DS9: "The Way of the Warrior")
Regardless of his optimism, in 2368 Worf was wary enough of a wounded and isolated Borg drone that he recommended killing it on sight, but his words went unheeded. The decision to rehabilitate the drone and return him to the collective nearly proved disastrous. (TNG: "I Borg", "Descent")
Like so many who have encountered the trickster, Worf immediately developed a strong antipathy towards Q. During their first meeting in 2364, Worf asked Picard, "and now, sir, a personal request. Permission to clean up the bridge?" (TNG: "Encounter at Farpoint")
In his latter visits, Q frequently took pleasure in teasing Worf, whom Q referred to as "micro brain". When Q forced the Enterprise-D crew to play out a detailed Robin Hood fantasy scenario, Worf found himself portraying the character Will Scarlet. When stripped of his powers from the Q Continuum, Q desperately asked how he could prove to the Enterprise-D crew that he was, indeed, mortal. Worf helpfully suggested, "die", much to the amusement of others present on the bridge. (TNG: "Hide and Q", "Qpid", "Deja Q")
Worf's exposure to Klingon society began in earnest in his time aboard the Enterprise-D. In a few short years, the forgotten orphan from the House of Mogh was a player in the highest levels of the Empire's politics.
In 2364, the Enterprise-D rescued three Klingons from a disabled cargo ship, and for the first time in nearly ten years, Worf spent time in the company of (renegade) Klingon warriors. One of the rescued was mortally wounded, and Worf joined in the Klingon death ritual for Kunivas, exposing non-Klingons to the event for the first time. The charismatic Korris tried to enlist Worf in taking the starship, but could not budge the officer's loyalty. In addition, Commander K'Nera also offered Worf a place in the Klingon Defense Forces, but was politely declined. (TNG: "Heart of Glory")
More than twenty years after the Khitomer Massacre, the honor of the House of Mogh was called into question in 2366. Worf's brother Kurn (see Family: Kurn) brought the news that Duras, of the rival House of Duras, had accused Mogh of betraying the Empire by facilitating the Romulan attack on the Khitomer colony. Worf appeared before the Klingon High Council to protest their judgment of guilt, and provided evidence that would have exonerated his father. Chancellor K'mpec dismissed Worf's defense, knowing the true traitor of Khitomer was Duras' father, Ja'rod. Considering the cost of his appeal and revelation of the truth – Duras' powerful clan inciting a civil war, and his intention to kill Kurn – Worf kept his silence and accepted a discommendation that ruined his name throughout the Empire. (TNG: "Sins of the Father")
A year later, Chancellor K'mpec was dying, and he asked Picard to serve as the Arbiter of Succession. The event coincided with Worf's reunion with K'Ehleyr, an iconoclastic ambassador and Worf's former lover, who introduced their child, Alexander (see Family: K'Ehleyr and Alexander).
The Sonchi ceremony over the body of K'mpec was interrupted by an attempt to assassinate Gowron. The contenders were offended by the dishonored Worf presenting the result of Enterprise-D's investigation, but Worf revealed evidence that implicated Duras. Concurrently, K'Ehleyr discovered the truth of Worf's discommendation as well as the scope of the House of Duras' treachery, but Duras confronted and murdered her. The question of succession was ultimately decided by Worf. Exercising his Right of Vengeance, he challenged Duras to duel, defeating and killing him. The death of Duras allowed Gowron to become the new Chancellor. (TNG: "Reunion")
The civil war K'mpec had feared broke out in late 2367, when the House of Duras and allies rebelled against Chancellor Gowron's leadership by attacking Gowron's ship, the Bortas. Worf felt it was his place to help his people, and resigned from Starfleet to side with Gowron. His influence proved instrumental in the war when he ordered Kurn to back Gowron. Worf would serve on Kurn's ship during the civil war, and fought at the Battle of Mempa. With help from Starfleet, the Romulan involvement was stopped, thus enabling Gowron's forces to quickly end the war and solidify his position as chancellor. In appreciation for Worf's help, Chancellor Gowron restored honor to the House of Mogh, gave his brother Kurn a seat on the Klingon High Council, and gave Worf the life of Duras' illegitimate son, Toral. Worf, unwilling to kill an innocent boy, let Toral go and returned to Starfleet without incident. (TNG: "Redemption", "Redemption II")
In 2369, while the Enterprise was docked at Deep Space 9, Worf was met by a Yridian named Jaglom Shrek. Shrek told Worf that Mogh may not have died at Khitomer after all and that he might have still been alive, living with Romulans in a remote prison camp. Worf decided to meet Shrek and guide him to the Carraya sector, where the prison camp was located.
On the surface, Worf found L'Kor, now an old man. L'Kor informed Worf that his father died at Khitomer, and that a number of prisoners were taken to this camp at the Carraya Sector. Worf attempted to free the prisoners, but instead was taken captive. Inside the main prison camp, Worf found Klingons and Romulans living together in harmony – in their isolation, the Klingons had abandoned Klingon concepts of honor and had forgotten their warrior ways. The Klingon elders laughed in disbelief at Worf's assertion that Klingons were allies with the Federation, but the younger people were fascinated by his ways and stories of Kahless. Despite attempts by Gi'ral to stop her daughter Ba'el's advances, the girl agreed to escape with Worf. However, when Worf found that Tokath, the Romulan leader of the camp, was Ba'el's father, he confronted Gi'ral about why she married a Romulan. Worf continued his influence on the camp's youth, and taught hunting to Toq. After catching an animal, they delivered it to the main hall as a feast. Tokath was horrified at the sight. Realizing that Worf would eventually sway the opinion of the other youths in the camp as he had Toq, Tokath sentenced Worf to death. However, Worf had exerted enough influence on the camp, and several members of the camp stood by Worf, willing to face execution rather than continue to live the way they had. Tokath was forced to let Worf return to the Enterprise. (TNG: "Birthright, Part I", "Birthright, Part II")
Although a profound influence on the settlers of Carraya IV, Worf's visit also forced him to challenge his beliefs. To renew his faith, Worf decided to visit the Caves of Boreth, and re-summon Kahless the Unforgettable. Kahless appeared before him for real – seemingly returned to lead the Empire once more. However, Worf was skeptical of the Klingon's authenticity. Gowron claimed that Kahless could not recall any of his legendary stories, and challenged him in combat, to which Kahless lost. The loss forced the clerics to reveal that this Kahless was a clone. Despite the discovery, Worf was instrumental in getting the clone installed as emperor to the Klingon people. The ceremonial position had not been held for centuries but Worf felt that the Klingon Empire had lost its way from Kahless' original teachings, and that the new emperor could bring further stability. (TNG: "Rightful Heir")
Other notable missions
Worf's first major task was to take command of the Enterprise-D saucer module and lead it to safety, when the ship separated prior to engaging Q for the first time. The order ran contrary to his nature (i.e. fleeing while his commanding officer was in danger) and Worf briefly objected, and Picard had to remind him of his duty. (TNG: "Encounter at Farpoint", "All Good Things...")
Worf was present for the first Federation contact with the Romulans since the Tomed Incident. A mysterious third party's devastating attacks on Romulan Neutral Zone outposts alarmed the powers on either side of the border. Worf was enraged by the prospect of dealing with the race responsible for the Khitomer Massacre, and was rebuked by both Picard and the Romulan Commander Tebok, who urged, "silence your dog, captain." (TNG: "The Neutral Zone")
That same year, Worf was a member of the away team sent to investigate the Iconian gateway located at the Romulan Neutral Zone. The experience with Iconian technology would serve him well many years later, in the Gamma Quadrant. On another away mission, to Theta 116 VIII, he participated in a recreation of the pulp novel The Hotel Royale. Worf revealed technical knowledge of a temporal anomaly. (TNG: "Contagion", "The Royale", "Time Squared")
Both Picard and Riker independently had Worf in mind as their top choice for the ops position when Data was presumed dead. Worf noted to Deanna that he served in this capacity before. (TNG: "The Most Toys")
At one point, the Enterprise was caught in an energy field which threw them away from an M-class planet inhabited by the xenophobic Paxans. The energy field was designed to erase the memories of the crew. However, Worf's surgically-mended arm proved that something happened at the Paxan homeworld, and that someone deliberately erased their memories of the event. To appease the Paxans, the crew agreed to have their memories erased again, only this time, no clues would be left. (TNG: "Clues")
A month later, the Enterprise became trapped in the Tyken's Rift while trying to find the USS Brattain. The insanity and fear brought out by the Tyken's Rift caused Worf to nearly kill himself with a ceremonial knife. (TNG: "Night Terrors")
When Keiran MacDuff altered the memories of the crew and the computer (including Data's) with a plasma energy beam, Worf temporarily took command of the Enterprise, because his sash gave the mistaken impression that he was the highest ranking officer. (TNG: "Conundrum")
In 2368, when the Enterprise was disabled by quantum filaments, Worf was entrusted with a makeshift infirmary in Ten Forward. During the incident, Keiko O'Brien went into labor, and Worf had to assist with her giving birth to Molly O'Brien. He would remember the incident for years, and bristle when he found out she was pregnant again later when they both were on Deep Space 9, determining to make sure he was on leave when she gave birth so he wouldn't be in a position to have to assist again. (TNG: "Disaster", DS9: "Accession")
In 2369, Worf was assigned by Admiral Alynna Nechayev to infiltrate Celtris III. Starfleet Intelligence had discovered bursts of theta-band subspace emissions from the planet, indicating an illegal metagenic weapon in operation. Worf, Dr. Crusher and Picard were part of the intelligence team sent to investigate. After Picard was captured by Gul Madred, Worf and Crusher escaped back to the rendezvous point, where they informed Captain Jellico of the situation. (TNG: "Chain of Command, Part I", "Chain of Command, Part II")
On stardate 47391.2 Worf began moving between many different alternative realities after flying through a quantum fissure in the shuttlecraft Curie. He experienced several unexplained discontinuities in events against his memory (particularly regarding his attendance and victory at the bat'leth tournament on Forcas III), and it was eventually discovered that Worf was not native to the universe he was currently in - a universe where the Federation was at war with the Bajorans, where he was a commander and first officer of the Enterprise-D and married to Deanna Troi, with whom he had two children. He was eventually returned to his original reality, apparently the only person to retain any memory of his journey. (TNG: "Parallels")
On stardate 48650.1, in 2371 Worf was promoted to Lieutenant Commander. He later assisted Commander Riker in identifying a weakness in Lursa and B'Etor's old D12 Bird-of-Prey. The ship was destroyed by the Enterprise in the battle of Veridian III. Unfortunately, due to heavy damage sustained during the battle, the Enterprise was destroyed shortly afterward. (Star Trek Generations)
Service on Deep Space 9
While awaiting reassignment following the destruction of the Enterprise, Worf took an extended leave of absence from Starfleet to evaluate his future. He returned his son to Earth to live with the Rozhenkos while he himself took refuge on Boreth. (DS9: "The Way of the Warrior")
Meanwhile, on the other side of the Federation, Captain Benjamin Sisko and the crew of Deep Space 9 were having trouble keeping order with the Klingons present at the station. When the treaty with the Klingon Empire was threatened during the Klingons' invasion of Cardassia in 2372 (after the Enterprise-D had been destroyed), Sisko stated, "Curzon told me once that in the long run, the only people who can really handle Klingons are Klingons." It was at this time he requested Worf's help.
Worf again became a player in galactic politics as the Federation tried to avert war between the Klingon Empire and the Cardassian Union. Worf was the Federation's best link to Chancellor Gowron and a meeting between them was arranged. He was asked to resign from Starfleet and join Gowron on the Klingon campaign to invade Cardassia. Worf felt the war was wrong and that it was incompatible with his loyalties with the Federation. As a result, Gowron threatened to strip Worf and his family of their honor, confiscate their lands, and treat them as traitors to the Klingon Empire. When Worf again refused Gowron made good on his threat.
The Klingons failed to bring down the Cardassian government with the Federation protecting them and an enraged Gowron withdrew the Khitomer Accords and made an enemy of the Federation. Following the mission, Worf was considering resigning from Starfleet to take a berth on a Nyberrite Alliance cruiser. After learning this, Sisko offered Worf a position as the strategic operations officer, which Worf humbly accepted. (DS9: "The Way of the Warrior")
When the USS Orinoco was sabotaged by the True Way in 2372, Worf, along with Major Kira Nerys, Sisko, Lieutenant Commander Jadzia Dax, and Chief Miles O'Brien were lost in the transporter. However, Odo and Michael Eddington managed to save their transporter signatures on the station's computers. The character data was saved in the holosuite (where Julian Bashir and Elim Garak were running a holosuite simulation). Worf's character data was superimposed onto Duchamps, a holosuite character who played the henchman to Dr. Noah. (DS9: "Our Man Bashir")
Worf's quarters on DS9 were on Level 3, Section 27, Room 19. (DS9: "Inquisition"). He also lived on the Defiant for a period of time (DS9: "Bar Association"). When Worf married Jadzia Dax, he moved into her quarters, which were located in the habitat ring, Section 25 Alpha. (DS9: "You Are Cordially Invited", "Resurrection")
USS Defiant missions
Whenever Sisko was not commanding the USS Defiant, Worf got a chance to demonstrate his command expertise. One of the first missions he commanded was the science mission headed by Lenara Kahn. The Trill science team was attempting to create Starfleet's first artificially-created stable wormhole. Worf found it hard to be excited about a science mission, claiming that his dreams were more exciting. (DS9: "Rejoined")
While beside a gas giant in the Gamma Quadrant, where the Defiant was escorting Quark to continue negotiations with the Karemma, the Jem'Hadar opened fire on the Karemma starship and the Defiant as punishment for their treason. Captain Sisko was severely injured in the incident, leaving Worf in command. Taking command in engineering (the bridge had been damaged by Jem'Hadar fire), Worf found many engineers (especially Muñiz and Stevens) unaccustomed to his authoritarian style of command. After receiving advice from Chief O'Brien, Worf undertook a more interactive approach. Better able to work under this style of command, Muñiz and Stevens were able to devise a way to destroy the Jem'Hadar attack ship. By modifying the main deflector, the Defiant successfully defeated the Jem'Hadar. (DS9: "Starship Down")
In a subsequent mission, Worf commanded the Defiant on a mission to escort Cardassian freighters across a volatile sector of Klingon space. After being fired upon by Klingon warships using a tactic of continually decloaking to fire and then recloaking, a Klingon ship decloaked directly ahead of the Defiant and Worf ordered it destroyed. However, this ship was a Klingon civilian transport ship. The Klingon Advocate Ch'Pok demanded that Worf be extradited to the Klingon Empire for punishment.
The Federation decided to stage an extradition hearing with Admiral T'Lara as chair and with Sisko as defense, and Ch'Pok as prosecution. Had it not been for Odo's discovery that there were no civilians on the destroyed ship, Worf would have been extradited to the Klingon Empire to face execution. After the court martial, which the defense won, Worf remarked about the difficulty of command. Sisko replied, "Wait until you get four pips on your collar. You'll wish you had gone into botany." (DS9: "Rules of Engagement")
Following a year of hostilities and border skirmishes between the Federation and Klingons (See: Federation-Klingon War (2372-73)), Odo discovered that Gowron may have been replaced by a Changeling. In order to establish whether Gowron was a shapeshifter, Starfleet Command ordered Sisko to lead a team (which included Worf) to expose Gowron as a shapeshifter. The team would pose as Klingon warriors being inducted into the Order of the Bat'leth. Each team member was to plant polaron emitters that, when activated, would force a shapeshifter to lose its shape. Worf initially found it difficult to turn the team into convincing Klingons. However, Sisko helped him refocus, and with practice, the team pulled through. The plan worked out relatively well on the surface, and Sisko was ready to activate the polaron emitter. However, just before he could activate the emitters, Martok, chief military adviser and overseer of the Cardassian invasion, recognized Sisko through his Klingon disguise, and the entire team were thrown into prison. While incarcerated, the team managed to explain their mission to Martok. It turned out that Martok had always suspected that Gowron may have been a Changeling, but he was waiting for the right time to expose him. With the polaron emitters destroyed, Worf decided that the only way to expose Gowron as a shapeshifter was to get him to spill blood. Once released by Martok, Worf fought Gowron in a duel. Gowron's Klingon honor and behavior led Odo to find it was not Gowron, but Martok who was the Dominion Changeling agent. After he was destroyed by the Klingon warriors, it was discovered that his mission was to destabilize relations between the Federation and the Klingon Empire. With Worf's help in uncovering the Dominion presence as the common enemy, he helped restore peace between the Federation and Klingon Empire. (DS9: "Broken Link", "Apocalypse Rising")
Some months later, the Defiant was tasked with the mission of sending the Bajoran Orb of Time back to the station. However, Defiant passenger Arne Darvin had other ideas, and used the Orb to travel back to 2268, to the time of Captain Kirk and the first USS Enterprise, and the year the tribbles had invaded Klingon space. Darvin's plot was to kill Captain Kirk and eliminate the tribbles before they had a chance to invade Klingon space. While searching for Darvin, Worf (along with Odo, Bashir and O'Brien) encountered Klingons scarred by the augment virus of the 22nd century. When Bashir and O'Brien asked how the augmented people could be Klingons, Worf could only respond with "We do not discuss it with outsiders." The crew apprehended Darvin on Deep Space Station K-7, and returned to the present. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")
The Dominion War
In 2373, Elim Garak had received an encoded transmission from his father, Enabran Tain. It stated that he had survived the Battle of the Omarion Nebula and was being held by the Dominion in the Gamma Quadrant. Garak convinced Sisko that he could enter Dominion space but only under supervision from Worf. In order to avoid detection while in Dominion space, Worf decided to hide in a nearby nebula. The diversion proved to be a bad idea, as that nebula housed the first Dominion invasion fleet, on its way to invading the Alpha Quadrant. Worf knew that they were planning to enter the wormhole, and that the Dominion War was about to begin. Before they were captured by the fleet, Worf managed to transmit a message to the wormhole relay station about the impending invasion. (DS9: "In Purgatory's Shadow")
Worf and Garak were taken to Internment Camp 371, where they discovered Enabran Tain, the real General Martok, and surprisingly, the real Julian Bashir. Bashir had been captured for a month and had been replaced by a Changeling infiltrator. All the prisoners knew they had to escape, to warn DS9 about the Changeling. Although Tain died at the camp shortly thereafter, Garak devised a plan to modify his transmitter to contact their runabout in orbit and escape from the internment camp. The transmitter was tucked away in a cramped compartment, and Garak had to overcome his acute claustrophobia to complete it. Worf and Martok commended Garak's courage, stating that "There is no greater enemy than one's own fears." During this time, to distract the Jem'Hadar guards, Worf entered into combat with each of the Jem'Hadar guards in turn, earning the respect and admiration of General Martok in the process, even winning the respect of Jem'Hadar First Ikat'ika, who yielded their final fate when he recognised that Worf's refusal to surrender meant that killing Worf would not be a victory. Once the prisoners escaped, they managed to warn DS9 that Bashir had been replaced by a Changeling. Kira managed to destroy the Bashir Changeling before he could blow up the Bajoran sun. (DS9: "By Inferno's Light")
From then on to the end of the year, the Dominion sent weekly fleets through the wormhole to fortify the Cardassian sectors. Starfleet, needing to find a way to halt the buildup, decided to block the entrance to the wormhole with a minefield. Sisko assigned the Defiant under the command of Jadzia Dax to deploy a field of self-replicating mines, all of which would need to be deployed before any could be activated. Starfleet forces were unable to assist in the deployment, so the Defiant and IKS Rotarran had to do it alone, and they only had one day to finish the minefield. Weyoun approached the station with 300 Dominion and Cardassian ships, and when Sisko refused their ultimatum, Gul Dukat opened fire, starting the Second Battle of Deep Space 9 and the Dominion War. While the Dominion's fire power proved ineffective against the station's shields, Worf, in command of the station's weapons array, managed to destroy fifty ships, and the Rotarran helped protect the Defiant so it could complete the minefield. With the minefield deployed, and the station vastly outnumbered, Sisko ordered all Starfleet crew members to evacuate the station. Due to the conquest of DS9 by the Dominion, Worf had been assigned to the Rotarran as first officer. (DS9: "Call to Arms")
Unlike the rest of Starfleet, First Officer Worf, ever the warrior, relished the opportunity to engage in combat with the Dominion. A joint operation where the Defiant played a decoy to three Jem'Hadar attack ships allowed the Rotarran to decloak and help destroy those ships in the front line. However, both ships had been called back to Starbase 375 for retreat. By now even Worf was beginning to lose morale from the retreats from the Dominion. What the alliance needed was a victory, something that Sisko had been planning all along – Operation Return, the plan to retake Deep Space 9.
The original plan of taking three Federation fleets and a Klingon contingent were scuttled when Sisko received word that the minefield was about to come down. The Second and Fifth Fleets had to take Deep Space 9 themselves. Even so, Martok and Worf tried to convince Chancellor Gowron to send some ships to the battle. Although it took a long time Gowron realized that both an ally and enemy were telling him the same thing, so agreed to send the ships. Outside the Bajoran system, the Federation was on the verge of losing the battle (Sisko had fallen for a trap set by the Cardassians), but then Worf and Martok's Klingon forces entered at an opportune moment. They inflicted enough damage on the Dominion for the Defiant to break through the lines. The Defiant went on to retake the station and win the battle. When the Jem'Hadar took command of the Defiant, and the crew pretended to make repairs to the warp core for their captors, Worf made it appear he was repairing the plasma display console but was actually sending signals to the bridge to give command operations to Sisko from main engineering. (DS9: "Favor the Bold", "Sacrifice of Angels", "One Little Ship")
Some time thereafter, Worf earned a second serious blemish on his service record when he abandoned an important mission for Starfleet Intelligence to rescue Jadzia Dax, who he had married shortly after the retaking of the station. Though no formal charges were leveled, due to the secrecy of the mission, Sisko said "this will go in your service record... and to be completely honest, you should know that they'll probably never give you a command of your own after this."
In 2375, Worf became disillusioned with the leadership of Gowron. Gowron feared Martok's growing popularity and devised a plan to discredit Martok and end any potential threat to his authority. Gowron began ordering Martok on near-suicidal missions against Dominion forces, hoping that a string of defeats would weaken Martok's popularity and discredit him as a military leader. Recognizing that Gowron was jeopardizing the entire war effort, Worf tried to convince Martok that he should challenge Gowron for the leadership. After Martok refused, Worf decided to challenge Gowron himself, citing his faulty battle planning, his dishonorable conduct in trying to discredit Martok, and poor strategies at the later stages of the Dominion War. After a brief battle, Worf killed Gowron; by right he was proclaimed the new chancellor of the Klingon High Council. However, Worf immediately gave his position to Martok. After the war, Martok asked that Worf be appointed Federation Ambassador to the Klingon Empire. Thereafter, Worf left Deep Space 9 to take his new post on Qo'noS. (DS9: "Tacking Into the Wind", "What You Leave Behind")
Service aboard the USS Enterprise-E
In 2373, Worf was ordered to take the USS Defiant and join the fleet of ships set to intercept a Borg cube in Sector 001 on a course for Earth. Along with the USS Bozeman and USS Lexington, the Defiant was heavily damaged by the cube and Worf was considering a kamikaze attack, when the USS Enterprise-E came to Worf's rescue. The Enterprise-E took on board the survivors of the Defiant, including Worf. Reunited with his old crewmates, Worf assisted in destroying the cube with the tactical information divulged by Picard. After it was destroyed, Worf discovered that a sphere was traveling back in time to 2063, in an attempt to prevent first contact between humans and Vulcans. After destroying the Borg sphere, Worf successfully helped destroy the Borg deflector array and prevented the Borg from changing history. (Star Trek: First Contact)
In 2375, Worf visited the Federation colony on Manzar to establish a new defense perimeter against the Dominion. At this opportunity, however, he visited his old friends on the Enterprise-E, which was on a diplomatic mission nearby. For a brief period Worf rejoined his old crew to reveal Admiral Dougherty's conspiracy concerning the Ba'ku relocation. (Star Trek: Insurrection)
In 2379, Worf rejoined his old crewmates from the Enterprise-E on Earth when he attended William Riker and Deanna Troi's wedding ceremony. Following the Earth wedding and while en route to a second ceremony on Betazed, the second wedding was postponed as the Enterprise-E detected positronic signals from the Kolarin system. Following the discovery that the source of the positronic signals was the Soong-type android, B-4, Vice Admiral Kathryn Janeway of Starfleet Command assigned the Enterprise-E to Romulus to begin new peace talks with the new Praetor of the Romulan Star Empire, Shinzon, who was a human clone of Picard. The peace offer turned out to be a trap and in the end Worf, together with Romulans, had to face Shinzon and the Remans. Finally, he admitted that the Romulans fought with honor, possibly overcoming his life-long grudge against this species. (Star Trek Nemesis)
Worf's intense desire to become a part of his lost culture was matched by enduring loyalty to the world that adopted him in his darkest hour. Those impulses forged a character of indomitable courage and integrity, uncompromising idealism, and a more-Klingon-than-Klingon facade that was occasionally lifted to reveal romanticism, gentleness, and humor.
While coming from a species frequently regarded as aggressive and enthusiastically boisterous, Worf often gave the first impression of being a rather dour and reserved, though surly and even vaguely threatening, individual. Beverly Crusher described Worf as a tall Klingon who rarely smiled. Likewise, Jadzia Dax referred to Worf as a man difficult to get along with, but she did see him as a good person. Jadzia admitted that whenever it came to Klingon culture, Worf would always get misty-eyed with sentiment. (TNG: "Remember Me"; DS9: "Children of Time", "You Are Cordially Invited")
Worf's conservative nature and respect for tradition occasionally brought him down on the side of issues that conflicted with the views of his friends. Antipathy for his species' historical enemy made him refuse to donate tissue from his body that may have saved a dying Romulan officer in 2366. He helped Rear Admiral Norah Satie uncover treason among the crew of the Enterprise-D in 2367, leading to unfounded accusations against Captain Picard and crewman Simon Tarses. After the witch-hunt was stopped, Worf apologized for the trouble he helped cause, but Picard commended his vigilance, reminding him of the difficulty of spotting a villain who operates with such subtlety. During what should have been a romantic vacation on the pleasure world of Risa, Worf joined Pascal Fullerton's New Essentialists movement, helping them to sabotage Risa's weather modification network. (TNG: "The Enemy", "The Drumhead"; DS9: "Let He Who Is Without Sin...")
Worf's reputation for a lack of humor inspired regular teasing from those close enough to get away with it, like Riker, or too powerful to care, like Q. It pleased Martok and Jadzia Dax to no end whenever they could squeeze a joke from the tight-lipped Klingon. Worf denied his lack of humor to Jadzia once, claiming that he was quite amusing on the Enterprise-D, causing her to theorize that "it must have been one dull ship." (DS9: "You Are Cordially Invited", "Change of Heart") Lwaxana Troi occasionally called Worf "Mister Woof", initially by mistake. Worf did not appreciate the misnomer. (TNG: "Half a Life", "Cost of Living", "Dark Page")
Although shy about it, Worf enjoyed singing Klingon operas. While at a bar on Qualor II in 2368, Worf requested that Amarie play Aktuh and Maylota and briefly graced the patrons with his baritone voice. He was stranded for some time in an escape pod in 2375, and passed the time taking advantage of the favorable acoustics. Though he initially denied the private performance, Ezri Dax guessed that he had been singing Shevok'tah gish. Chagrined, he admitted to actually singing Gav'ot toh'va, a piece with rather ambitious solos. (TNG: "Unification II"; DS9: "Penumbra")
The combination of his human upbringing and Klingon taste buds made for an unusual palate. Among traditional Klingon foods like live gagh for breakfast, he loved his mother's version of rokeg blood pie. (TNG: "Family") Guinan introduced Worf to a treat that he relied on with regularity for satisfaction, his "warrior's drink". (TNG: "Yesterday's Enterprise") Riker once prepared scrambled 'Owon eggs for friends in his quarters, and while the humans regarded the result as tasting terrible, Worf (after a careful sniff) scarfed up his, simply remarking "delicious". (TNG: "Time Squared") He did not react well to Romulan ale, and agreed with its prohibition. (DS9: "Inquisition"; TNG: "Parallels"; Star Trek Nemesis)
Worf was an admirer of Natasha Yar and her martial arts skills, and joined her on the ship's parrises squares team. Three days before she died, Worf placed a wager that Yar would be victorious in an upcoming martial arts competition. (TNG: "11001001", "Skin of Evil")
Worf ran regular Mok'bara classes, of which Deanna Troi and Dr. Crusher became regular students. Worf ran several classes of varying difficulties, such as the beginning and advanced levels. (TNG: "Birthright, Part I", "Birthright, Part II")
As a Warrior
Worf was a proven expert with both the bat'leth and his favored weapon the mek'leth. He had won a bat'leth tournament on Forcas III just before his birthday in 2370. Worf also defeated and killed both Duras and later Gowron in honorable combat, both men were at one time considered to be the most prominent warriors in the Empire; Worf's skills as a Warrior ushered in two successive Klingon Rulers - Gowron in 2367 and Martok in 2375.(TNG: "Reunion", DS9: "Tacking Into the Wind") While teaching his moves to his young son Alexander, he described the bat'leth as an extension of one's body. (TNG: "Reunion", "Parallels")
In 2366, the fugitive Roga Danar escaped the brig of the Enterprise-D to return to Lunar V, Worf led the security staff in an attempt to recapture. Roga managed to evade phaser explosions, transporter locks, decompressions and force fields to reach the shuttlebay. Worf and Roga fought hand-to-hand but his opponent's genetic enhancements proved too powerful for Worf. (TNG: "The Hunted")
Worf's unarmed combat skills progressed to the point that, while being held in a Dominion prison camp, he defeated twelve consecutive Jem'Hadar soldiers in honorable combat, and forced the thirteenth, an Honored Elder, to yield in deference to his courage. Martok promised that when they return to the Empire he would seek out Keedera himself so a song would be written of Worf's accomplishment (DS9: "By Inferno's Light").
Worf was considered to be a Warrior of great renown. Advocate Ch'Pok refered to Worf as "a famed Klingon Warrior" (DS9: "Rules of Engagement") Tumek recognized Worf by his uniform alone. (DS9: "Looking for par'Mach in All the Wrong Places") General Martok knew of him by name when Worf introduced himself in Internment Camp 371. (DS9: "In Purgatory's Shadow") His prowess as a warrior was respected enough that Klingon Chancellor Gowron diverted his entire fleet to Deep Space 9 to offer Worf a post at his right hand during the invasion of Cardassia. (DS9: "The Way of the Warrior")
Ailments and injuries
Worf would get sick to his stomach when he was in zero gravity. (Star Trek: First Contact)
During a diplomatic mission to convey delegates from the Beta Renner system to Parliament, Worf was temporarily possessed by an energy being, displaced from its natural environment by the passing of the Enterprise-D. The being passed on to Beverly Crusher and eventually, Captain Picard, before the incident was resolved. (TNG: "Lonely Among Us")
Later in 2364, Q had transported Worf and the rest of the crew of the Enterprise down to the surface of an unknown planetoid, possibly created by Q, where they were attacked by a group of musket-wielding aliens wearing 18th century French army uniforms. Unarmed, Worf charged the aliens and defeated some of them but was eventually stabbed in the abdomen with a bayonet by one of the aliens and died moments later, only to be revived by William T. Riker, who was temporarily in possession of Q powers. (TNG: "Hide and Q")
The ship had picked up a Zalkonian in the final stages of an evolutionary change. Since he had suffered memory loss, the crew just referred to him as John Doe. When Worf tried to stop him from stealing a shuttlecraft, John Doe emanated an energy bolt in self-defense. Unfortunately, that bolt proved to be fatal to Worf, who had been declared dead by the medical crew. However, John Doe's strange transformations allowed him to heal Worf's injury and restore his life. (TNG: "Transfigurations")
Worf never really liked doctors ("any doctors"); however, there was one doctor that has earned Worf's respect more than any other. In 2365, Dr. Katherine Pulaski discovered Worf suffered from rop'ngor, normally a childhood disease, and protected his dignity by keeping his illness secret. In gratitude, Worf invited Pulaski to participate in a Klingon tea ceremony, where he beguiled her with Klingon love poetry. (TNG: "Up The Long Ladder"); DS9: "Doctor Bashir, I Presume")
Once while checking cargo containers a large one fell on Worf, injuring his back and leaving him paralyzed. Unwilling to live on as a paralyzed Klingon, Worf asked his commanding officer Riker to perform the hegh'bat. Riker refused to aid such a ritual, quoting "that right falls to the eldest son". Opposition from Riker, Troi and Dr. Crusher, in addition to Alexander's lack of knowledge of Klingon culture led Worf to change his mind. He permitted Dr. Toby Russell to perform a dangerous and experimental procedure to replace his spinal column. The surgery was a failure, and Worf was declared dead. However, due to the redundancies of Klingon physiology, where every organ in the Klingon body had a backup organ that activates whenever damage occurs to the first, his internal backups were initiated and Worf woke up. It took time, but with the help of his son and Troi, Worf made a full recovery. (TNG: "Ethics")
Worf was apparently allergic to cats, as evidenced in 2370 when Lieutenant Commander Data asked him to temporarily care for his cat, Spot, when he sneezed loudly while carrying her out of Data's quarters. The incident startled Spot. (TNG: "Phantasms")
While the Enterprise was upgrading its sensor array, Worf, along with Riker, Kaminer, Edward Hagler, Sariel Rager, and La Forge, was abducted by mysterious solanogen-based lifeforms for strange experiments. Since they were abducted in their sleep, many began to experience afterimages of the experiments. Worf experienced one such flashback when he went to get his hair cut by Mot. When he saw the scissors Mot would be using, it reminded him of the blade used to probe him. In order to discover the location of the aliens, Worf suggested planting a homing device on Riker so when his next abduction came, they would locate him and the aliens. (TNG: "Schisms")
Later that year, when the Enterprise became affected by Barclay's Protomorphosis Syndrome, Worf was one of the first crew members to devolve. He de-evolved into a Klingon prehistoric venomous predator, and after he sprayed Beverly Crusher with venom, he went on a rampage and terrorized the entire ship, killed Ensign Dern, and tried to mate with Deanna Troi, who had devolved into an amphibian creature. (TNG: "Genesis")
While the rest of the Enterprise-E crew enjoyed the age-reversing qualities of exposure to metaphasic radiation on the planet of the Ba'ku, Worf suffered the indignity of an affliction normally suffered by Klingons half his age, a gorch. (Star Trek: Insurrection)
Worf dated K'Ehleyr, a Human-Klingon woman, while he attended Starfleet Academy, but the relationship at the time ended acrimoniously. In 2365, while K'Ehleyr served as a Klingon emissary, she had to board the Enterprise-D to deal with a Klingon sleeper ship from the 23rd century. The two briefly rekindled their relationship when a joint holodeck training exercise led to a Klingon mating ritual. Worf, at the time, insisted that they take the oath of marriage afterward, but K'Ehleyr refused, stating, "Don't give me any of that Klingon nonsense." K'Ehleyr paid no heed to Klingon tradition, as she felt that she inherited the worst traits of her respective parents' races (her Human mother's sense of humor, and her Klingon father's temper). They parted afterward, resolving their feelings before her departure from the Enterprise-D. (TNG: "The Emissary")
Unbeknownest to Worf, however, the mating ritual led to K'Ehleyr becoming pregnant with their child. K'Ehleyr returned to the Enterprise-D in 2367 to participate in the succession of Chancellor K'mpec, and took the opportunity to introduce their son, Alexander, to Worf for the first time. In the intervening years she found she needed Worf after all, and wanted to finish the mating ritual. This time Worf backed off, unwilling to permit his intervening discommendation to discredit either K'Ehleyr or Alexander. Worf's refusal to detail the nature of his discommendation prompted K'Ehleyr to start her own investigation, an action that triggered the attention of Duras and her subsequent murder. Worf and Alexander found K'Ehleyr dying from multiple stab wounds. Her whisper confirmed the identity of her killer, and she brought Alexander's small hand to his father's as she died.
Worf performed the Klingon death ritual and consoled his son in Klingon fashion before he abandoned the symbols of Starfleet and Empire. With only his bat'leth, he boarded Duras' ship, the IKS Vorn, claiming the Right of Vengeance under Klingon law. After the first blows were exchanged, Duras reminded Worf the cost of victory – Duras' death meant Worf's family name may never be cleared. Worf's family name suddenly meant little against the memory of K'Ehleyr, and he answered, "Then that is how it shall be!", and left Duras' corpse on the deck (see also: Alexander). (TNG: "Reunion")
Worf was unaware of Alexander's existence for the first years of the boy's life, until K'Ehleyr introduced their child in 2367. Under the Empire's discommendation at the time, Worf hesitated to acknowledge his son and thus perpetuate dishonor into the next generation of the House of Mogh. As K'Ehleyr lay dying from the stabs of Duras, her last act was to bring the pair together. Worf raged the Klingon death ritual, terrifying his son, but he brought Alexander to his mother for the last time, telling him, "You have never seen death... then look – and always remember." After avenging K'Ehleyr's death, Worf confirmed to Alexander that indeed he was his father (see also: K'Ehleyr). (TNG: "Reunion")
K'Ehleyr held little regard for Klingon traditions, let alone indoctrination, conflicting with Worf's theories of Klingon child-raising . Despite trying to teach Alexander about the Klingon artifacts located in his quarters (including a bat'leth), Alexander seemed to show no interest. After K'Ehleyr's death, Alexander was sent to live with his grandparents, but the Rozhenkos found that raising a Klingon child was now more than they could handle in advancing years. Helena returned the boy within a year to be with Worf. Lwaxana Troi's influence added to Worf's headaches, but father and son settled in to a home life aboard the Enterprise-D. (TNG: "New Ground", "Cost of Living").
Worf and Alexander played sheriff and deputy pursuing a dangerous criminal in an ancient-west theme holodeck program. One of Data's experiments accidentally turned all the holodeck characters into manifestations of Data, and disabled the holodeck safety protocols. With his son Alexander kidnapped, Worf arranged for his return by agreeing to a duel with the villain in the town square. Worf managed to survive by manufacturing a makeshift force field. (TNG: "A Fistful of Datas")
When Alexander was approaching his first Age of Ascension, Worf was appalled to discover that Alexander did not want to become a warrior. An encounter with K'mtar (a future Alexander from an alternate timeline) forced Worf to let Alexander follow his destiny. (TNG: "Firstborn")
Once the Enterprise-D was destroyed, Alexander was sent back to his grandparents. While he was growing up, Alexander decided he wanted to join the Klingon Defense Forces after all, eventually ending up on the Rotarran, Martok's ship. When reporting for duty, he referred to himself as Alexander Rozhenko instead of the son of Worf. A confused Martok asked what this house of Rozhenko was, to which Worf replied that Alexander was his son. Martok and Worf became concerned when Alexander was not getting along with his Klingon comrades. He interrupted a fight between Alexander and Ch'Targh when Alexander was on the verge of losing. Alexander revealed that he hated feeling like the unwanted son that Worf would rather get rid of. Worf tried to explain that the Jem'Hadar will not go easy on him, and that if he didn't learn how to fight quickly, they would kill him. After Alexander mistook a battle simulation as the real thing, the crew accepted him as the ship's fool. However, in the real battle, he successfully sealed a leaking plasma impulse injector. After this victory, Martok and Worf deemed him worthy of joining the House of Martok. (DS9: "The Way of the Warrior", "Sons and Daughters")
When Alexander revealed that he would be transferring to the IKS Ya'Vang, Jadzia Dax decided to push forward her wedding ceremony to before he left so that he could serve as Worf's Tawi'Yan. With the date moved up, Alexander was allowed to participate in Worf's Kal'Hyah ceremony (Klingon bachelor party), along with Sisko, Martok, Bashir and O'Brien. Despite being a Klingon, he struggled through the ceremony almost as much as Bashir and O'Brien. (DS9: "You Are Cordially Invited")
Jadzia Dax was Worf's second mate, and the first woman he ceremonially took as his wife. The two became good friends because of Curzon's understanding and interest in Klingon culture. When they first met at Quark's bar, he instantly recognized the station's science officer as the new host of Curzon, a name honored amongst Klingons, to which Jadzia responded (in Klingon) that she is more attractive than Curzon was. Worf, however, was distracted by Drex, attempting to stir up trouble in the bar. When Worf managed to stop Drex and take his dagger, Dax said in amazement, "He's good."
When Worf moved his quarters to the Defiant, Jadzia gave him her collection of Klingon operas, and suggested that he play them through the Defiant's communications systems. Worf accepted them as a thoughtful gift, especially after Nog retuned and remastered them. (DS9: "Bar Association", "In the Cards")
Worf became romantically involved with Jadzia Dax in early 2373. It started when Quark's former wife Grilka came aboard the station. When Worf developed an instant crush on Grilka, he couldn't fathom how she could have married a Ferengi. Jadzia's explanation of the full story (DS9: "The House of Quark") merely exacerbated Worf's confusion. In order to win her heart, Worf decided to perform deeds that were overtly Klingon, such as throwing Morn off of his stool, demanding bloodwine, and insulting Grilka's bodyguard, Thopok. However, since Mogh's family honor had been disgraced, Grilka could not possibly mate with Worf.
Dejected, Worf chose to help Quark win Grilka's heart, with advice from Jadzia. By controlling Quark's movements using a remote control device, he helped Quark defeat Thopok and win the heart of Grilka. Then Jadzia jumped on Worf and the pair had their own mating ritual. As required by tradition, Worf demanded that Jadzia marry him, but Jadzia understood that Worf was not a traditional man, and they agreed to a more gradual exploration of their relationship. (DS9: "Looking for par'Mach in All the Wrong Places")
The romance had a rocky start. In their first holiday together (on Risa), Worf grew immediately jealous of Arandis, the chief facilitator at the resort planet and Curzon's former lover. Even though Jadzia explained that she had moved on long ago, Worf remained suspicious. However, after a heart-to-heart talk with him, Jadzia helped Worf get over his jealousy. (DS9: "Let He Who Is Without Sin...")
When Dax found out from Sisko that Worf would be accompanying Elim Garak on a suicide mission to find Enabran Tain, she took back her Klingon operas, motivating Worf to survive his mission to the Gamma Quadrant with an embrace. (DS9: "In Purgatory's Shadow")
When war broke out between the Federation and Dominion in late 2373, Worf and Jadzia were separated when they were reassigned. Dax was given command of the Defiant, while Worf was assigned to a Klingon ship. Jadzia vowed that when DS9 was retaken and they returned to their former positions, Jadzia would wed Worf. This spurred Worf on through the early days of the Dominion war. While all of Starfleet was grim from the news that the Seventh Fleet had been defeated at the Tyra System, Worf could only think of one thing: the fact that the ritual targ sacrifice would take place after the wedding ceremony, where tradition dictated that it take place before. He was bugging Martok about it ever since they left Deep Space 9. He was, however, concerned for Dax's safety after her symbiont was injured when she bore the brunt of an explosion near an M-class planet in a dark matter nebula. When she was rescued by the Rotarran, Worf was relieved to see she recovered from the injuries. (DS9: "Call to Arms", "A Time to Stand", "Rocks and Shoals", "Sons and Daughters")
Following the successful Operation Return in early 2374, Dax decided to marry Worf within the week. All she had to do was appease Lady Sirella, mistress of the House of Martok, and Sirella would wed the two. This proved more difficult than expected, since Sirella, not wanting aliens to pollute her house, opposed the marriage. When Dax refused to stop a party, an enraged Sirella screamed that there would be no Klingon wedding. When Dax asked for a Bajoran-style wedding led by Sisko, a quivering Worf decided to call the whole thing off. After some fence-mending by Sisko, Dax and Worf eventually resumed the wedding, and the pair married in Quark's Bar. (DS9: "You Are Cordially Invited") Later on, after Jadzia lost a game of tongo to Quark, Worf, who had also lost a bet on that game to Miles O'Brien, then told Jadzia afterward that he would rather lose a bet on her than win one on someone else. Jadzia felt that was one of the most romantic things Worf had ever said to her. (DS9: "Change of Heart")
The marriage proved strong. When Lasaran, a Cardassian defector, contacted Starfleet Intelligence in 2374, Worf and Jadzia were ordered to rendezvous with him and return him safely to Federation space. During the mission Jadzia was seriously wounded by a Jem'Hadar energy weapon. The anticoagulant properties of the weapon put Jadzia's life in danger and Worf abandoned Lasaran in order to save her. The action caused Worf to receive a reprimand, and Captain Sisko believed it would prevent him from ever receiving his own command, but Worf stated he had no regrets. (DS9: "Change of Heart")
By late 2374, Jadzia and Worf had decided to attempt parenthood, despite the extreme difficulties posed by the disparate biologies of Trill and Klingons. Worf had already proved his ability in fatherhood by babysitting the O'Briens' son, Kirayoshi, and with the help of Bashir, Jadzia and Worf could attempt to conceive. In thanks she visited the Bajoran temple on the Promenade, where she was attacked and killed by Gul Dukat, who was possessed by a Pah-wraith and was attempting to destroy the Orb kept in the temple. (DS9: "Time's Orphan", "Tears of the Prophets")
In the Enterprise's second Officer Exchange Program, Worf was reunited with his brother Kurn, whom he had not seen since he first left his homeworld as a child. Kurn used the exchange program as pretence to reunite with Worf, and to inform Worf that his honor was put into question because the Klingon Empire announced that their father had betrayed the Klingons at the Khitomer colony by giving the Romulans strategic information. When Worf challenged this ruling, Kurn was also present. When Worf decided to accept the dishonor (to prevent civil war), it was also decided to keep Kurn's bloodline secret to protect his honor. (TNG: "Sins of the Father")
When Gowron ascended to the throne after the Klingon Civil War and restored the honor of the House of Mogh, Kurn gained a seat in the High Council. For a time, it seemed that the house of Mogh would thrive and would even one day inherit the throne, but then Worf condemned the Klingon invasion of Cardassia.
Four months after Kurn lost his seat on the Klingon High Council, he arrived at DS9 seeking help from his brother to perform the Mauk-to'Vor ritual. He felt that the ritual, which involved Worf killing him, was the only way to restore his honor. After receiving orders from Sisko not to carry out the honor killing, Worf arranged for his brother to have cosmetic surgery and his memory wiped so he could start a new life with no ties to the House of Mogh. (DS9: "Sons of Mogh")
Worf always had high respect for Martok, even when he was replaced by a Changeling. In 2373, Worf found the real General Martok in Dominion Internment Camp 371. Martok was forced to face the Jem'Hadar in daily fighting contests (one of which led to the loss of his eye), until Worf replaced him. The way Worf won each battle so impressed Martok that he felt his actions were worthy of song. Having been healed by Bashir, and trained by Martok, who was at ringside for each of his contests, Worf defeated all the Jem'Hadar guards, so the Jem'Hadar First, Ikat'ika, presented himself as Worf's next challenge. Worf, already badly injured by previous fights, was losing and was about to let Ikat'ika kill him, when he experienced a moment of tova'dok with Martok. Worf stood back up one more time, refusing to yield to Ikat'ika. It was then that Ikat'ika realized that he could not defeat his opponent, only kill him, something which "no longer held his interest". Ikat'ika himself yielded the match. Deyos, the leading Vorta officer of the facility, had Ikat'ika executed for refusing to kill Worf. It was at that moment that Garak had finished the transmitter and all the prisoners escaped back to Deep Space 9.
With approval from Worf, Sisko, and Gowron, Martok was honored by being made commander of the detachment of Klingon soldiers assigned to the station. (DS9: "In Purgatory's Shadow", "By Inferno's Light")
Martok was given command of the IKS Rotarran and requested Worf to be first officer, with Jadzia Dax the science officer. His first mission was to locate the missing cruiser IKS B'Moth. A string of defeats against the Jem'Hadar had sapped the Rotarran's crew's morale to the point where dishonorable conduct and dereliction of duty were commonplace. When Martok refused to engage the Jem'Hadar, the crew of the Rotarran decided to mutiny, and Worf challenged Martok himself, accusing him of being a coward. In the fight, Martok severely injured Worf and retained command, and gained the crew's loyalty. This new loyalty would lead to the Rotarran's first victory over the Jem'Hadar, and the rescue of the B'Moth. Rather than punish Worf for mutiny, he thanked him for reminding him of his duty as a soldier of the Empire, and offered him a place in his House as a "brother". Together, the "brothers" turned a low-morale vessel that was on the brink of mutiny into the Klingon Empire's most distinguished ship. (DS9: "Soldiers of the Empire")
Worf, Alexander Rozhenko, Jadzia and Ezri Dax were all adopted into the House of Martok. Driven to the brink of madness by Worf's single-mindedness and longing for Dax, he could not be more pleased that the wedding to Jadzia was going ahead. He participated in Worf's Kal'Hyah ceremony (one of the few participants who had an easy time), and when Worf got cold feet, he convinced Worf to put the wedding back on track. After Jadzia died, Worf became concerned that her death was not honorable enough for her to enter Sto-vo-kor. Worf needed to win a glorious battle in her name for her to enter it, and General Martok gave him such a mission – destroy the Dominion shipyards of Monac IV. (DS9: "You Are Cordially Invited", "Shadows and Symbols")
In late 2375, Worf was instrumental in bringing Martok to power as chancellor when he challenged the authority of then-chancellor Gowron. Upon killing Gowron in battle, Worf ceded his new position as chancellor to Martok. (DS9: "Soldiers of the Empire", "Sons and Daughters", "Tacking Into the Wind")
Worf had a contentious relationship with his elder foster-brother, Nikolai. Cavalier, inspired, and rebellious, Nikolai's antics – and the pains he caused in their mother – invoked the ire of his dutiful, honor-conscious brother. Nikolai thought of Worf as a perfectionist, and resented him never being wild or disobedient. But the sibling tensions between the two seemed to be of a commonplace, Human variety. Later in life, reflecting on their childhood together, neither man made note of their genetic differences as a source of their friction. When asked if he and Nicolai were close, Worf considered, and merely said, "we are... brothers." (TNG: "Homeward")
Nikolai at the Boraalan homeworld, Worf (disguised as a Boraalan) was shocked to discover his foster brother, had violated the Prime Directive. Worf, who was a firm believer in the Prime Directive, (TNG: "Pen Pals") discovered that Nikolai had become much more involved with the Boraalans than necessary. Nikolai conceived a child with a Boraalan female, Dobara, and became very protective of the Boraalans in her village. Although his actions saved the Boraalan race (whose homeworld had been rendered uninhabitable by atmospheric dissipation), it took the holodecks of the Enterprise and vast amounts of power to keep them from finding out. While the Enterprise shipped the villagers to their new home on Vacca VI, Worf and Nikolai navigated them through an ever-changing holographic landscape (subtly altered so it would end up resembling their new home). As the power started running out, the holodeck was beginning to have trouble maintaining cohesion, and parts of the holodeck started manifesting itself. Worf calmed the villagers, claiming the images to be the sign of La Forge. They reached the new home just as the holographic simulations ran out of power and ended. (TNG: "Homeward")
The crew of the Enterprise
In the holographic message Natasha Yar composed before her death, she noted her commonality with Worf, as orphaned warriors, and called him a kindred spirit. When Worf assumed Yar's duties after her death, he promised to uphold her example. (TNG: "Skin of Evil")
Though Worf was beginning to feel the Enterprise-D was becoming a true home, there came a point in 2365 when the isolation from his native society could not be ignored. Wesley Crusher's brush with a cranky Klingon inspired him to investigate, and discovered the cause of Worf's discontent. In a holodeck re-creation of a Klingon Rite of Ascension chamber, his loyal friends gathered to celebrate the tenth anniversary of his Age of Ascension and witnessed Worf endure the traditional gauntlet of painstiks. They had never seen him happier. (TNG: "The Icarus Factor")
Worf became a fixture at the senior officer's weekly poker games, where he liked to give the impression he took the game as seriously as combat. The "Iceman", as Riker sometimes called him, relished exorbitant bets and insisted that Klingons never bluffed (an assertion later proven false). In one game, he was prepared to wager his goatee against Beverly Crusher's hair color. (TNG: "The Emissary", "The Quality of Life")
Guinan once asked Worf why he always sat alone. Worf looked at her with vague irritation and replied that he would require a Klingon woman for companionship, since "Earth females are too fragile." Despite Guinan's claim she knew one or two women on board who may have found him a bit tame, an amused Worf refuted this as "impossible". (TNG: "Yesterday's Enterprise")
Arctus Baran's capture of Picard and Riker left Data in temporary command of the Enterprise-D for period in 2370. Worf's evident dissatisfaction with Data's command decisions quickly grew into open criticism – improper conduct from an acting first officer. Data was forced to privately chastise Worf for his behavior, and quickly added his regrets if the confrontation ended their friendship. Chagrined, Worf acknowledged his errors and admitted that if their friendship had been threatened, it was his blame alone. (TNG: "Gambit, Part II")
He took the disgraced Ensign Sito under his wing, helped her regain an exemplary service record (after her involvement with the Nova Squadron crash two years previous), and got her recruited for a dangerous mission to Cardassia Prime, a mission she never returned from. Upon hearing this, Worf joined her friends for a drink at Ten Forward. (TNG: "The First Duty", "Lower Decks")
In the 2366 incident of Galorndon Core, the Enterprise rescued a fatally injured Romulan soldier named Patahk. Dr. Crusher discovered that he had cell damage to several vital areas that would require a transfusion of compatible ribosomes and only Worf could provide the cells. Due to memories of the Khitomer incident and his distrust in Romulans, Worf refused to donate his blood. Patahk mutually agreed with Worf's decision, saying he would rather die than have his "cells polluted with Klingon filth". Picard tried to make Worf reconsider, asking (and soon begging) him for a favor as a friend, not as his commanding officer. Since it was not an order, Worf stuck with his decision not to donate blood and Picard respected his choice. Patahk died soon afterward. (TNG: "The Enemy")
When Picard was taken prisoner and replaced by a duplicate, the crew discovered the imposter from his differing behavior. Worf was one of the officers who mutinied against the imposter to side with Riker. When the real Picard returned to the Enterprise, he only needed one glance to initiate a series of events which would culminate in Worf trapping the aliens. (TNG: "Allegiance")
When the honor of Mogh was called into question over the Khitomer incident, and Kurn could not serve as cha'DIch, Worf chose Picard to act as his cha'DIch. Picard accepted, and successfully uncovered the truth about the Khitomer massacre. The truth led to Worf and Picard's contempt for the House of Duras, who were the real traitors. (TNG: "Sins of the Father")
Picard's successful tenure as Arbiter of Succession to the Klingon Empire gave Worf added respect for Picard. Despite Worf having killed Duras, going against the Federation charter and Prime Directive, Picard forgave Worf for the incident although he gave his security chief a reprimand. (TNG: "Reunion")
When the Enterprise-E was taken over by the Borg and Picard opposed the recommendation to abandon ship, Worf was labeled a coward by Picard, and responded, "If you were any other man, I would kill you where you stand," implying great admiration. Picard later admitted that Worf was the "bravest man" he had ever known, (Star Trek: First Contact) and they both shook hands in comraderie.
Worf met Guinan when she first came aboard the Enterprise. Guinan introduced Worf to what would become his favorite drink, prune juice. As Guinan sat down at his table, she asked why Worf always sat alone. Worf looked at her with vague irritation as the conversation was venturing into areas he'd rather avoid. Worf replied he would require a Klingon woman for companionship, as human females were too fragile. Despite Guinan's claim she knew one or two women on board who may have found him a bit tame, a very amused Worf refuted this as "impossible". (TNG: "Yesterday's Enterprise")
Guinan and Worf competed with each other in the phaser range. During the 2367 Klingon civil war, Guinan asked Worf about how his son, Alexander, was doing. Worf replied he was having difficulties adjusting to life on Earth, to which Guinan responded the time would come when Alexander found out what it really meant to be Klingon, just as the time had now come for Worf. (TNG: "Redemption")
William T. Riker, a jovial and amiable man in general, got along well with Worf. In some instances, he managed to bring out eruptions of emotion that his stoic lieutenant strived to keep in reserve. When Riker was heady with the powers of the Q, he eagerly tried to share the experience with otherwise impossible gifts for his friends. He noted Worf's isolation from his native culture, and with the best of intentions, he gave Worf an aggressively lustful Klingon female. Enraged and embarrassed, Worf refused the woman, admitting that the world she represented was alien to him and he had no place for such a "gift" in his life at the time. (TNG: "Hide and Q")
As a vital, athletic man who participated in dangerous sports like parrises squares and anbo-jytsu, Riker might have liked to think he could keep up with a younger Klingon, and joined Worf in his brutally violent Klingon calisthenics holodeck program. The exercise ended with all opponents defeated, and Worf was looking for more, rather intently, and in the specific direction of his increasingly alarmed partner. Riker hastily called an end to the session. (TNG: "Where Silence Has Lease")
Sometime after those events – where Worf had risked offending (or worse) his superior officer with a sense of impunity – a minor gesture by Worf innocently reached out to reciprocate the proffered friendship. When Riker proudly prepared 'Owon egg omelettes for a meal with his gathered friends, only Worf could stomach the dish, eating with obvious pleasure and declaring the eggs "delicious". (TNG: "Time Squared")
Riker's practical experience with other Klingons, begun in the officer exchange program, engendered an understanding of the Klingon culture that the other Enterprise-D officers, save perhaps Picard, lacked. Worf helped bring this about, by briefing Riker with his own knowledge of the rules of the chain of command in the Klingon Defense Force. When the time came for them to participate in battle exercises in preparation for the Borg threat, Riker was given command of the USS Hathaway to serve as the Enterprise-D's opponent. As Riker's first officer, Worf brought "Klingon guile" to bear (as the barely spaceworthy Hathaway had little else to offer), giving the Enterprise-D a worthy challenge and even coming to her aid against the Ferengi marauder Kreechta. (TNG: "A Matter Of Honor", "Peak Performance")
Their friendship was jeopardized for a time, after Worf began a romantic relationship with Deanna Troi in 2370. Riker's long history with Troi remained evidently unresolved, a fact that Worf was keenly aware of, and Troi refused to discuss. Picard's experience in an alternate future revealed how the existing tension could grow into naked animosity between the rivals for Troi. By that timeline they had long been estranged and had no desire to mend fences with each other. During a skirmish with the Klingons, they openly blamed each other for putting the rest of their still-mutual friends in danger. By sharing that foresight with his officers, Picard gave Worf and Riker the chance to halt their schism before it could fully form, and they continued to be close friends. (TNG: "All Good Things...")
In 2371, the senior officers gathered in the Enterprise-D holodeck for an age-of-sail-themed celebration, marking Worf's promotion to lieutenant commander. As was customary for Enterprise officers on such occasions, Worf was made to "walk the plank" over open water, and forced to leap upward to grab the dangling symbol of his new rank. Worf was the only officer in the ship's history to succeed in maintaining his balance, and dignity, by keeping his footing on the precipice. Unsatisfied with the precendent, Commander Riker ordered the holodeck computer to instantly remove the plank, using the holodeck's ability to disintegrate holographic matter. His order was mildly chastised(though not without amusement) by Picard, who indicated that the correct expression was to retract the plank. Riker shouted an apology to Worf, who was splashing and cursing angrily in the water. (Star Trek Generations)
Worf was distrustful and uneasy around telepaths, but ship's counselor Deanna Troi became a trusted exception. When he was severely injured in 2368, he asked her to care for Alexander if he died. By late 2370, Worf asked her to become a soh-chim to Alexander, a role she gladly accepted. (TNG: "Dark Page", "Ethics", "Parallels")
After an encounter with alternate realities showed him a life with Troi as his wife, Worf's eyes were opened to a new possibility, he began to pursue her. Though surprised, Troi welcomed the advances, and the two enjoyed a romantic relationship through 2370. Deanna wasn't thrilled by Worf's concern for Will Riker's interest in the matter, but the triangle's tension was eased by the advice of Captain Picard. (TNG: "Parallels", "Eye of the Beholder", "All Good Things...")
By the next year, the romance seemed to have dissolved amicably, and eventually, she and Riker resumed their relationship. Worf's only visible unease at their wedding in 2379 was the result of imbibing too much Romulan ale, and the prospect of appearing naked at their Betazed marriage ceremony. (Star Trek Generations; Star Trek: Insurrection; Star Trek Nemesis)
Deep Space 9 companions
By contrast, Worf found it quite difficult to adjust to life aboard Deep Space 9, right from the day he arrived. When Worf entered Quark's bar, Quark asked if he wanted bloodwine (since he was Klingon, and every Klingon Quark met ordered only bloodwine). When Worf asked for prune juice, Quark laughed in disbelief. Worf did not share his humor, so Quark was forced to bring him the prune juice. It would be the first of many confrontations with Quark, and the Ferengi in general (whom Worf thought unworthy to serve in Starfleet). (DS9: "The Way of the Warrior", "Little Green Men")
When Worf discovered Quark was dealing with a smuggling operation, he was confounded as to why security officer Odo never arrested Quark. After a disappointing response, Worf decided to take matters into his own hands. When the next smuggled crystal arrived, Worf stepped forward and arrested Quark. It was then that Odo shapeshifted himself and revealed the entire operation as a setup. Odo was going to follow the smuggler and uncover the entire Tarkalean smuggling operation. However, thanks to Worf's interference, Odo had to settle for the middle man. (DS9: "Hippocratic Oath")
Events came to a head one day when Worf's quarters were robbed by a burglar. The response by Odo proved to be disappointing to Worf. This event happened to coincide with a union strike taking place in Quark's bar. Dr. Julian Bashir and O'Brien were betting who would enter Quark's bar despite the strike. Both unanimously agreed that Worf would not enter the bar, recalling he would rarely enter the bar even before the strike. When they saw that Worf actually entered the bar, O'Brien approached Worf to talk some sense into him. This proved a serious mistake, and led to the three of them being thrown into the brig. At this final incident, Worf decided that the only way to adjust to life aboard the station was to live outside it, on the Defiant. Eventually, Worf managed to adjust to the activities of the station, even enjoying a Ferengi tooth sharpener in the process. (DS9: "Bar Association", "Little Green Men")
Worf and Benjamin Sisko became personal friends thanks to Sisko's experiences with Curzon and Jadzia, as well as being Worf's defense in his extradition proceedings against Ch'Pok and the Klingon Empire. Sisko also risked his own life to keep Worf alive. The Defiant crew had joined the Dominion in an attempt to destroy the Iconian gateway at Vandros IV. Worf was one of the officers who found tolerating the Jem'Hadar difficult. After a brawl erupted between Worf and Toman'torax (who was threatening O'Brien at the time), Omet'iklan decided to have both officers punished. For his disobedience, Toman'Torax's punishment was execution by his commanding officer, Omet'iklan. Upon seeing that Sisko's punishment would merely be confining Worf to quarters, Omet'iklan described the Federation as weak, and vowed to kill Sisko once the Iconian gateway was destroyed. Worf vowed to avenge Sisko's death if Omet'iklan succeeded in carrying out his threat. (DS9: "Rules of Engagement", "To the Death")
When it was discovered that there was a Changeling in a high position in the Klingon Empire, Worf took part with Sisko in a daring mission to uncover the identity of the changeling and helped to train the human officers to better appear as Klingon warriors. (DS9: "Apocalypse Rising")
When Kira was praying for the Emissary during his visions of 2373, Worf surprisingly understood her faith in the Prophets (as opposed to the rest of the crew). He felt that the strength of Sisko's faith would be what pulled him through. (DS9: "Rapture")
Worf helped Sisko capture and apprehend the Maquis leader, Michael Eddington. He helped reorganize the Defiant after its computers were disabled by Eddington's cascade virus. Worf also modified and fired a quantum torpedo so it would release trilithium resin into the atmosphere of Solosos III, the act of which forced Eddington to surrender. Worf had assumed the quantum torpedo was going to be used on Eddington's Maquis fighter. (DS9: "For the Uniform")
When Garak persuaded Sisko that he could enter the Gamma Quadrant to search for Enabran Tain, he only allowed him to do so if Worf could accompany him. Later, Worf asked Sisko if he could join General Martok on the Rotarran; Sisko needed a good officer like Worf defending the station, but Worf described his moment of tova'dok with Martok and convinced Sisko to allow Worf to join the Rotarran. He did not oppose Martok's request that Worf remain on the Rotarran even after the Operation Return, knowing that he was the only officer he knew that could never get enough work. (DS9: "In Purgatory's Shadow", "Soldiers of the Empire")
When Sisko was reassigned to Starbase 375 in 2374, leaving Jadzia Dax to command the Defiant to the Argolis Cluster, both he and Worf were concerned for the safety of the ship and her crew. Sisko reassured Worf that Dax would want to get back for the wedding, while Worf suggested that Sisko get some rest. (DS9: "Behind the Lines")
Sisko took part in Worf's Kal'Hyah ceremony, and tried his best to last the entire four days. He motivated O'Brien, Bashir and Alexander throughout the entire four day ceremony. After Sirella called off the wedding, Sisko convinced both officers that they were in love and that they could not call off the wedding. (DS9: "You Are Cordially Invited")
Worf took command of the Defiant, trying to search for survivors of the USS Honshu, gunned down by Cardassian destroyers. Two of the survivors were Sisko and Dukat, trapped near the Badlands. When Kira relayed Starfleet's orders to call off the search for Sisko, the message came through garbled with interference. Despite Bashir's claims that the message was too unclear to understand, Worf knew what the message ordered, and said it would be dishonorable to disobey them. Fortunately, Dukat relayed a distress signal detailing the location of Sisko. (DS9: "Waltz")
Worf would participate in Sisko's grudge game against former Academy classmate, Captain Solok. Although he performed well in training, Worf received three strikes when he faced the Logicians. Both Sisko and Worf were enraged that he did not obtain a single run. (DS9: "Take Me Out to the Holosuite")
Worf knew Chief O'Brien from his early days in the Enterprise, although their relationship was that of a noncom and his superior. However, they would both be participants in the crew's poker games. O'Brien would be a participant in Wesley Crusher's Age of Ascension recreation for Worf, where he would comment on the power of the Klingon painstiks. (TNG: "The Emissary", "The Icarus Factor").
Although Worf had to man the bridge at O'Brien's wedding to Keiko, he gave O'Brien a Klingon weapon as a wedding gift. In 2368, when the Enterprise was damaged by a quantum filament, Worf was forced to deliver Keiko's baby daughter, Molly. He humorously noted that Molly resembled Miles. (TNG: "Data's Day", "Disaster")
The friendship would really take off when Worf transferred to Deep Space 9. O'Brien was the first person to greet Worf when he arrived. Later he introduced Worf to the game of darts, describing it as "poker, but with pointed tips." Once Worf accepted the role of strategic operations officer (with a change of uniform from yellow to red), O'Brien commented how good Worf looked in red. (DS9: "The Way of the Warrior")
When the Defiant was damaged by the Jem'Hadar during their Karemma negotiations, and Worf found commanding the engineering team difficult, it was O'Brien who helped Worf take a different approach to command. (DS9: "Starship Down")
When Worf discovered that the O'Briens were having another child, he altered his holiday plans to coincide with the birth, just so he wouldn't have to deliver O'Brien's baby (like he did with Molly). (DS9: "Accession")
During Worf's trial that demanded his extradition to the Klingon Empire, O'Brien described Worf as "an honorable man". In turn, Worf described O'Brien as an "outstanding officer" and a friend, relaying their mutual respect out loud. (DS9: "Rules of Engagement")
In 2373, Worf participated in recovering a Jem'Hadar ship from Torga IV, the last mission of Enrique Muñiz. Although Worf believed that Muñiz would not survive from his wounds, O'Brien did not agree and clashed with Worf's pessimism. Worf was later proved right however, and Muñiz did pass away. Once the mission was over, O'Brien and Worf performed the Klingon tradition of ak'voh in front of Muñiz's casket. (DS9: "The Ship")
O'Brien had to undergo a ritual fasting with Julian Bashir and Sisko as part of Worf's Kal'Hyah ceremony, which was different than what he thought it would be. He couldn't last the four days (even vowing to kill Worf at one point), and when he heard the wedding ceremony was called off, he and Bashir immediately ordered a large feast of Earth and Bajoran food. However, Sisko stopped them and helped put the wedding back on track. (DS9: "You Are Cordially Invited")
At one point, Worf and O'Brien, while watching Jadzia and Quark playing a game of tongo against each other and a group of Ferengi waiters, Worf made a bet that Jadzia had the game in hand. He wagered to O'Brien that if she won, he would owe Worf a bottle of bloodwine. If Jadzia lost, however, Worf would then owe the chief a bottle of Irish whiskey. In the end, however, Worf ended up saying that he would need time to come up with O'Brien's payment. (DS9: "Change of Heart")
Worf was more than happy to babysit Kirayoshi while the O'Briens were busy taking care of Molly, who travelled through an ancient time portal. Once Kirayoshi was returned to his parents, he chose to honor their dinner invitation rather than go in a holosuite.
After Jadzia Dax died at the hands of Gul Dukat, O'Brien was one of the first people who attempted to cheer up Worf. While drinking bloodwine and reminiscing about old crewmates (most notably, Reginald Barclay), O'Brien found out what was bothering Worf – the fact that his wife did not die an honorable death, and thus could not enter Sto-vo-kor. O'Brien then directed Martok to help Worf, who assigned him the mission to destroy the Monac IV fleet yards. (DS9: "Tears of the Prophets")
It was O'Brien who helped Worf ease his hostility to Ezri. Over a bottle of bloodwine, O'Brien asked how Jadzia would feel if she knew how poorly Worf treated Ezri. When Worf claimed that there was no way to know, O'Brien refuted the claim, suggesting he talk to the one person Worf had been avoiding. After keeping her in Starfleet, Worf and O'Brien attended Ezri's promotion party. (DS9: "Afterimage")
When O'Brien's authorization code was used to access sixteen cases of bloodwine sent to Martok by Sirella, Martok and Worf had to quiz O'Brien on where the cases went. O'Brien had to explain to Worf and Martok that Nog must have taken the bloodwine to barter for a graviton stabilizer. Worf and Martok gave O'Brien one day to find the bloodwine. Fortunately, Nog had returned with 16 cases of 2309 bloodwine bought from his cousin Gant, an even better vintage than the ones Nog took. Both Klingons gave O'Brien a bottle of the bloodwine as an "apology". (DS9: "Treachery, Faith and the Great River")
Ezri Dax's relationship with Worf did not go quite as smoothly as Jadzia's, despite many of Jadzia's friends and colleagues quickly accepting the presence of a new Dax in their lives. Initially, Worf wanted nothing to do with her, or even Dr. Bashir, considering Ezri's presence and her relationship with Bashir an affront to his wife's memory. However, he soon realized that his actions were more of an affront, and relations between them began to warm. (DS9: "Afterimage")
During the latter half of the year, Worf commanded the IKS Koraga when it was destroyed by the Dominion; his escape pod was rescued by Ezri Dax, with whom Worf was captured by the Breen. After undergoing an interrogation (which included killing one of the clones of Weyoun), Worf and Ezri were freed by Legate Damar as part of his resistance to the Dominion. (DS9: "Penumbra", "Strange Bedfellows")
Although Kurn's new life gave him a chance to regain honor, Worf had to continue living with his dishonor. Kor (considered a hero, according to Worf) offered him the perfect opportunity to regain his honor. Kor, who disliked the High Council enough to consider any enemy of it a friend, revealed to Worf that he and Jadzia knew the secret location of the legendary Sword of Kahless, stolen by Hur'q pillagers a millennium ago. If Worf could find the sword and present it to the present emperor it would almost certainly restore his honor among his people. Kor accepted Worf's request to join the expedition, knowing it would annoy Gowron.
Although the antechamber that apparently held the sword had been ransacked, Worf discovered that a holographic projection hid the true chamber. With the help of some Hur'q DNA, Kor, Worf and Dax gained access to the hidden chamber, where they found the legendary sword. Worf believed that the discovery of the sword was one of the events in his life that his vision of Kahless foretold him accomplishing.
When the team exited the chamber, they came face-to-face with Toral, son of Duras, an individual whose life Worf had spared following the Klingon Civil War. After a brief battle with Toral and his bodyguards, the team made a dash back to the ship, being chased by Toral. However, while heading back to the ship, Kor and Worf encountered a difference of opinion about the sword. Worf was disgusted when Kor used the sword to eat a vole: "The sword is not something that you use to shovel food down your mouth." When it came time to sleep, Kor and Worf could not sleep, for fear that if they did sleep, the other would seize the opportunity to steal the sword and reap the glory. After a restless night, the team had to maneuver across a steep chasm. Kor lost his footing and nearly fell down the slope. Worf, barely able to hold onto Kor, told him to let go and drop onto a ledge beneath him. Kor, preferring to die rather than let go of the sword, refused and climbed back up with the help of Dax. Kor took a look at the ledge, and found that it was too small to support his weight. This proved too much for Kor, and he decided to fight Worf in battle. If it wasn't for Toral catching up to the team, they would have killed each other. After dealing with Toral, the team realized how much the sword was dividing two Klingons. They decided that the Empire was not ready for the return of the sword, so they beamed it into space, to be lost until Klingons were ready for it. (DS9: "The Sword of Kahless")
In 2375, when Kor came to the station looking for command of a ship, Worf discovered that Martok held a personal grudge against Kor. Kor was responsible for striking Martok’s name from the officers' list because his family was from the lowlands of Ketha Province, and due to his influence, Martok was barred from even enlisting as a common soldier. In order to mend ties between Martok and Kor, Worf managed to sneak him into the IKS Ch'Tang. The Ch'Tang was part of a small fleet assigned to raid the Dominion base on Trelka V. Kor was experiencing lapses in concentration, one of which nearly led to the destruction of the Ch'Tang. While trying to retreat from enemy space, the crew discovered they were being pursued by ten Jem'Hadar fighters. If the Ch'Tang could not find a way to delay the Jem'Hadar fighters, they would not be able to reach friendly space in time. Worf planned to use the IKS Ning'tao to divert the pursuers, a move that would be suicidal. However, before he could reach the transporter, Kor used a hypospray to take Worf's place. Although Kor would not return from the battle, he bought enough time for the Klingon fleet to escape. (DS9: "Once More Unto the Breach")
Alternate realities and timelines
- When the Template:ShipClass starship USS Enterprise-C emerged from the temporal rift in 2366, it created an alternate timeline. In this new timeline the Federation was suddenly at war with the Klingons, causing Worf to disappear, replaced by Natasha Yar, who, in our own timeline, died in 2364. (TNG: "Yesterday's Enterprise")
- In a computer fantasy created by Barash for Riker, Worf had gained a scar from an unknown battle, a fact which Riker used to prove he was in a fantasy. (TNG: "Future Imperfect")
- After he returned from a bat'leth tournament on Forcas III, Worf had encountered a quantum fissure, where he was shown to have been married to Deanna Troi in two alternate timelines.

It was in this same timeline that Worf had been promoted to full commander and appointed first officer of the Enterprise-D. (TNG: "Parallels")
- In an unknown, alternate future timeframe, Worf had been reluctant to become involved with Troi, and her subsequent death led to a rift between William Riker and himself as a result. He later served as a member of the Klingon High Council, and was the governor of the Klingon colony of H'atoria. (TNG: "All Good Things...")
- In an alternate timeline created by the Defiant's time travel back 200 years, Jadzia Dax and Worf had married and fostered a large family whose descendants formed a significant part of a colony numbering 8,000 people, including Yedrin Dax and Brota. (DS9: "Children of Time")

- Worf was played by Michael Dorn throughout his time on TNG and DS9, and in all four TNG movies. In addition, he also appeared prominently in the game Star Trek: Armada. Due to his appearances as a regular in eleven seasons (seven in TNG and four in DS9), four movies, and six games (and counting), the character Worf holds the record of the most appearances in Star Trek.
- Worf also holds the record for the most revivals in Star Trek. He was killed three times, TNG: "Hide and Q", "Transfigurations", "Ethics", and each time recovered. However, Kathryn Janeway has the record for the most "deaths" at nine.
- Part of the premise Gene Roddenberry wrote for Star Trek: The Next Generation was that it was set at a time when Klingons had set aside their differences with the Federation, and had become their allies. Robert Justman proposed a "Klingon Marine" serve on the Enterprise as a symbol of this. The character was later made a full Starfleet officer, and was one of the last additions to the permanent cast. Dorn, an avid fan of Star Trek, then got his opportunity to play Worf, the first Klingon in Starfleet.
- Worf's originally planned backstory, in the "TNG Bible", was that he had been on a Klingon ship in one of the last Earth-Klingon battles; and had been rescued by Starfleet, at the age of 8. The episode "Heart of Glory" established the slightly different backstory involving the sneak Romulan attack on Khitomer.
- Worf's first-season baldric was made of fabric, not metal, and was exactly the same style as worn in TOS by Kor ("Errand of Mercy") and Kang ("Day of the Dove"). However, it is unknown whether the accessory was recovered from old TOS costumes or re-created for TNG.
- In his online review of TNG: "Hide and Q", Wil Wheaton made a comment on Worf's early character and giving Dorn respect for playing Worf as he was back then. Wheaton said he couldn't imagine what it must have been like for Dorn in that first season, describing first season Worf as "one-dimensional and so incredibly stupid." Wheaton also noted that Dorn didn't do much more than Denise Crosby did in those early episodes, and in contrast to Crosby, who quit the show out of frustration, Dorn stayed with it, and over time was allowed to develop Worf into a much more complex and beloved character, eventually becoming a regular on DS9, and also being in all the TNG movies.
- As part of several sweeping changes for Deep Space Nine's fourth season, Worf was added to the regular cast list as the station's strategic operations officer, a position he held until the end.
- When asked why he returned to Star Trek, actor Michael Dorn stated, "What interested me was the idea that my character, and I always loved my character, I really was close with him, the idea that my character would grow even more, and that I would become a larger part of the Star Trek universe than I already was, that's what interested me. And I told the producers, and we had many discussions about that that's what attracted me back." (Crew Dossier: Worf, DS9 Season 4 DVD special features)
- Ira Behr, Deep Space Nine's executive producer, said that fitting Worf into the show was one of the biggest challenges he had to face during the show's run. However, he felt he had managed this task well. He remarked, "Obviously, one of the reasons Worf was brought on the show was to increase the ratings. After all, they call it show "business". But if we did not feel that Worf would've brought something to the party, we never would've done it. Sometimes business decisions and artistic decisions can ride the same wave." (AOL chat, 1997)
- Similarly, as Behr's writing partner Robert Hewitt Wolfe states, "In the beginning it was difficult, I gotta be honest with you, to integrate this new character, but that was good because it challenged us, and made us sort of re-examine the show in a whole new light. How do we make this guy work? How do we bring him in? How does he change the relationships for all of our characters? He stirred up the whole thing again, gave the whole show sort of a second phase, or a second stage rocket. Suddenly, there's Worf and we've got to deal with him and his issues, and suddenly there's Klingons everywhere and that brought a new favor to play with." (Charting New Territory: Deep Space Nine Season Four, DS9 Season 4 DVD special features)
- Ronald D. Moore has also commented, "I've been happy to see the changes in the character since he was brought onto DS9 – I think we ran the danger of "de-fanging" Worf by the end of TNG and there's been a concerted effort made to roughen him up and give him some sharper edges. He's more likely to err now, more likely to do the wrong thing for the wrong reason... I think that makes him more interesting as a character and more compelling to write for." (AOL chat, 1997)
- Michael Dorn summates his portrayal of Worf by saying, "Only time will tell, in a way, you know what I mean, what my contribution is. If anything, I'd like to think that I took a character that was not a major character to start with and brought him into the light. It's sort of like one of those things where it's not so much that 'Oh yeah, the star, I have to be the star' and dadada, but the character was not a major character, he was there, but he wasn't a major character. And I was able to bring whatever it is I brought to the character to put him closer to the forefront. I think it kind of bears up because, you know, out of all the people they got to go on Deep Space, who knows? But the character played well on the show, and helped the show over the years. If I had to be remembered for something, that'd be it." (Crew Dossier: Worf, DS9 Season 4 DVD special features)
- Worf is one of four characters to appear in two series finales, (TNG: "All Good Things..." and DS9: "What You Leave Behind") the others being Miles O'Brien, William T. Riker and Deanna Troi.
- Worf's orphaning and subsequent adoption by the Rozhenkos was seen in the The Lost Era novel The Art of the Impossible.
- In Peter David's Star Trek: New Frontier and Starfleet Academy novels, Worf's roommate at Starfleet Academy was Zak Kebron, a Brikar who later became a prominent character in the New Frontier novel series.
- Worf's somewhat ill-defined role in the initial stages of the series is explained in The Buried Age as being the "chief bridge watch officer" whose duties were to essentially fill in where needed, which allowed him to gain command experience. According to the novel, Worf had put in for security but Picard refused, saying that he needed more experience which would give him more opportunities later on. When Worf says he will do his best to learn all he can, Picard tells him he will be expected to learn all he can.
- The novel A Time for War, A Time for Peace, established that Worf decided after several various events had occurred, that he was not of the right temperament to be the Federation ambassador and although the new Federation president disagreed, she accepted his resignation. Worf then nominated his son Alexander, to be his replacement as Ambassador. Worf decided that after serving the Klingon Empire and the Federation and always doing what was expected of him that the time had come for him to be selfish and he wanted to go back to Starfleet, where he felt the most fulfilled. Admiral Ross immediately reinstated his rank of Lt. Commander and assigned him to be first officer on the Titan under Captain Riker. Worf was filling in at the tactical station during the events of Star Trek Nemesis as the Enterprise's chief of security, Christine Vale, had taken shore leave on Earth and the second in command of security had recently resigned. After the events of Nemesis, in the wake of Data's death, Picard asked Worf to remain aboard the Enterprise and Worf agreed. Novels set after Nemesis, such as Resistance, Before Dishonor, Q&A, and Greater than the Sum, showed Worf serving as acting first officer and then initially refusing the position on a permanent basis. Worf felt that he did not deserve it after what happened back on Soukara and how he abandoned the mission to save Jadzia. After rescuing Picard from the Borg and receiving some sage advice from Dr. Crusher, Worf accepted the position on a permanent basis and was promoted to the rank of commander.
- In the Playstation game Star Trek: Invasion, Worf was put in command of the Typhon from early to mid-2376. After the Valkyrie Squadron was put on active duty, Worf left the Typhon.
- A picture of Worf can be found in Star Trek: Voyager - Elite Force on USS Voyager inside the quarters of Alexandria Munro should you choose the female character in the game.
- The comic book series Star Trek: Countdown, a tie-in to the 2009 Star Trek film, depicted Worf as a general in the Klingon Defense Force in 2387. Worf was critically wounded by Nero while on board the Narada and was last seen unconscious on the USS Enterprise and about to be transported to sickbay.
- In Star Trek Online, Worf has remained ambassador to Qo'noS and remains one of the few pro-Federation voices in the Empire after the breakdown of the Khitomer Accords. He weds Grilka and they have one son. In describing her to reporter Jake Sisko, he echoes his previous comments on her, saying "She is glorious." He later denounces the Federation when they refuse to help the Klingons fight an Alpha Quadrant infiltration of Species 8472.
