Vioxx

Commander Vioxx was the captain of the Romulan scout ship Tyvek, which was assigned to explore the Delta Quadrant. The Tyvek was lost to the Lucinda entity, but Vioxx and his officers were able to escape to a nearby habitable planet. They were nearly eaten by a family of the planet's inhabitants but were rescued by the USS Anomaly. Vioxx received orders from the Romulan High Command to have the Anomaly follow Lucinda but not tell Captain Reginald Bain or the crew about the actual threat. The Anomaly was able to deal with Lucinda. After this incident, though, Romulan High Command insisted that Vioxx and his officers stay aboard, so the Romulans would be more involved in the Anomaly's day-to-day operations. Vioxx was made the ship's first officer. (Bold Faced Lies [BG])

During the battle at the Neutral Zone against the combined Vulcan and Romulan fleets, Vioxx led Sub-Commander Remax and Sub-Lieutenant Zantak in stealing the Raceabout USS Silverwood to get aboard a Romulan warhawk. Once aboard, they incapacitated the crew, and Remax was able to determine that the Romulans aboard had been victims of mind melds. Vioxx took command of the warhawk and used it to help the Federation fleet in battle. (Live Long And Conquer [BG])

After hostilities with the Vulcans ended, Engineer Selex approached Vioxx with the idea that Commander Prosak had to be killed, due to her RommaVulc allegiance. It was Vioxx's duty to kill her, since he was the ranking Romulan officer. Vioxx at first dismissed the idea, but after Sub-Commander Remax explained how it could possibly lead to all of them being sent back to the Empire and Vioxx receiving command of a warhawk, Vioxx said he would consider it.

While Vioxx was at the Romulan Imperial Academy, he was involved with the daughter of one of Romulus' elite families, who had rebelled against her upper class parents and decided to serve in the Romulan military. Eventually, she left Vioxx and the Academy to return to the comfort of her old life.
