This page contains information regarding Star Trek: Picard, and thus may contain spoilers.
Rios was born in Chile on Earth. His mother taught at Starfleet Academy. When he was about eight years old, Rios sneaked into a flight simulator there and scored higher than any cadet in history. (PIC: "Assimilation", "Monsters")
Rios, a former Starfleet commander, rose to the post of executive officer on the USS Ibn Majid, a heavy cruiser, where he served under Captain Alonzo Vandermeer. His serial number was SC-850-705. (PIC: "Broken Pieces")
In 2390, while patrolling the Vayt sector, the Ibn Majid encountered a small ship of unknown origin, and brought aboard its two passengers, Beautiful Flower and Jana. The Captain received a "black flag directive" from Starfleet Security to kill the two beings, otherwise his ship would be destroyed with all hands. Rios confronted Vandermeer, after he murdered the two beings with his phaser, and the Captain shot himself in the mouth.
Rios covered everything up, just as Vandermeer was ordered to do in order to protect the crew. He beamed the bodies into space, deleted the transporter logs, and told the fleet that the Captain had committed suicide for no reason. Six months later, Rios was discharged from Starfleet, officially for post-traumatic dysphoria. (PIC: "Broken Pieces")
Captain of La Sirena
By 2399, Rios had become acquainted with Raffi Musiker, and had assumed command of the starship La Sirena, serving with his fully utilized Emergency Hologram basic installation, each of which was programmed in his own image due to his choosing the self-scan option upon his acquirement of the ship. One was an Emergency Medical Hologram (EMH) which was programmed with a light English accent and named Emil. Another was an Emergency Navigational Hologram (ENH) which was programmed with a light Northern Dublin Irish accent and named Enoch. One was an Emergency Hospitality Hologram (EHH) which was programmed with a Midwestern American accent and aptly named Mister Hospitality. Another was an Emergency Tactical Hologram (ETH) which was programmed to speak Spanish and was named Emmet. Lastly, there was the Emergency Engineering Hologram (EEH) which was programmed with a Scottish accent and was named Ian.
Return to Starfleet
Life in the 21st century
After correcting the timeline, Rios chose to stay in 2024 with Teresa Ramirez and her son Ricardo. Together, Rios and Teresa formed the Mariposas, a medical movement. Rios captained the Mariposas through tough times and hard terrains while Teressa helped whoever needed help whenever they might need it. Ricardo would eventually go on to form a team of the brightest minds in the world who figured out how to use the alien organism brought back by Renée Picard from the Europa Mission to heal the ocean and clean the sky.
For the rest of his life, Rios and his family remained close friends with Guinan and presumably Renée who became Ricardo's "Auntie Renée." Teresa eventually died of old age while Rios died "slightly younger" in a Moroccan bar fight over medical supplies and his last breath was into a cigar.
After returning to 2401, Jean-Luc Picard visited Guinan who showed him a picture of Rios and Teresa and informed him of their fates along with some funny stories about his old friend. (PIC: "Farewell")
He was a fluent speaker of the Spanish language.
When Rios was a child, his mother often sang him the lullaby "Arroz con leche". In 2399, he stated that he has no family. He also said that he liked to pretend that Vandermeer was his father. Internally, he called Vandermeer "Pops", and had even nearly did so out loud a couple of times. (PIC: "Broken Pieces")
Although they had only known each other for a few hours, Rios was close to the android Jana, as evidenced by his knowledge that Soji liked to dip her french fries in peppermint ice cream; something Jana also did. He kept a drawing among his possessions from his time in Starfleet that showed him posing with an arm around Jana's shoulder and with a big smile. He also had other drawings of her alone, and confined himself to quarters when the incident aboard the Ibn Majid was brought up. In addition, Rios referred to Soji as "hija" (a Spanish term commonly translated as "daughter") when chastising her after she tried to pilot the ship to her home world on her own. (PIC: "Broken Pieces")
Despite his negative feelings towards Starfleet due to the circumstances of his departure, after having spent years in the service Rios kept up certain habits when it came to his ship. Having just boarded for the first time, Picard had quickly noted that La Sirena was kept in impeccable shape, and that her captain had maintained and stowed everything in accordance with Starfleet protocol. (PIC: "The End is the Beginning")
Rios had a romantic relationship with Agnes Jurati as the two shared a kiss after the events in the Ghulion system. (PIC: "Et in Arcadia Ego, Part 2") The two were no longer a couple by 2401. (PIC: "The Star Gazer")
After time traveling to 2024, Rios and Doctor Teresa Ramirez expressed an interest in each other. (PIC: "Mercy") This ultimately led him to remain in the 21st century with her, while the others returned to their own time. (PIC: "Farewell")
He was an avid reader and kept a number of printed books in his quarters and lying around the ship. In addition to having read one of Jean-Luc Picard's books, he was fond of existentialist philosophy, having read philosophers such as Miguel de Unamuno, which he described as concerning "the existential pain of living with the consciousness of death and how it defines us as Human beings."
