Voq was a Klingon and a fanatical follower of T'Kuvma. Outcast from Klingon society for his albino skin, Voq referred to himself as "son of none". He later assumed the name of Ash Tyler and posed as a Human to gather information from Starfleet.
In 2256 aboard the Sarcophagus, Voq volunteered to take on the role of Torchbearer after the death of Rejac. T'Kuvma initially rejected him, citing that the position of Torchbearer belonged to one of noble birth. Voq argued that his faith made him worthy – that he had been reborn through the flames of Kahless – which he demonstrated by burning his fist in a lit brazier. Accepting Voq to be a mirror of himself, T'Kuvma gave his own bat'leth to Voq and charged him with the Torchbearer's sacred duty of lighting the Beacon of Kahless. (DIS: "The Vulcan Hello")
When the Klingon High Council answered the summons of the Beacon, Voq was the first to respond to their communications. He was treated with contempt by the leaders of the Great Houses, particularly Kol. Nevertheless, Voq ardently proselytized T'Kuvma's vision of a purified Klingon Empire united against the Federation. Following their victory over Starfleet in the Battle of the Binary Stars, Voq urged the High Council again to follow T'Kuvma, whom his compatriot L'Rell proclaimed as T'Kuvma "the Unforgettable".
Voq attacked Commander Michael Burnham after she and Captain Philippa Georgiou boarded the Sarcophagus to capture T'Kuvma. However, Burnham defeated him and ultimately fatally shot T'Kuvma. Voq held his dying lord and vowed that all Klingons would rally behind T'Kuvma's memory. (DIS: "Battle at the Binary Stars")
After the battle, the Sarcophagus, commanded by Voq and L'Rell, was stranded for months with no functioning drive and lack of food. Eventually, most of T'Kuvma's house submitted to Kol of the House of Kor, while Voq was left on the wreck of the USS Shenzhou. L'rell beams over and tells Voq she is still on his side. She tells him she has a raider ship for him to use to reach the matriarchs of her sect to learn powers he cannot yet imagine. (DIS: " The Butcher's Knife Cares Not for the Lamb's Cry")
"Voq. Son of none."
"You cannot assume the birthright of a noble house. You are unworthy."
"I am worthy. not by blood...but by faith"
"I serve the light of Kahless. I am reborn in his flames."
"Open your hearts to the one who delivered this great day. Follow the light. Follow T'Kuvma."
"Your life will remembered forever by all Klingons. Your death will be a cause to unite us all."

Voq was portrayed by actor Shazad Latif. Prior to the revelation that Tyler actually was a disguised Voq, Voq was credited in episodes as being played by "Javid Iqbal". Latif chose the name of Javid Iqbal to appear in his credits in memory of his deceased father.
Originally, CBS announced in December 2016 that T'Kuvma's protégé, then named "Kol", was to be played by Shazad Latif. In the final version of the series, Latif went on to portray Ash Tyler and T'Kuvma's protégé was renamed "Voq", while the name Kol was given to a leader of a rival Great House.  Ultimately, however, it would turn out that the character of Ash Tyler was actually a construct for Voq to infiltrate Human society.
