In the mirror universe, Commander Tebok was a Romulan military officer who lived during the 24th century. By 2371, he was in command of the D'deridex-class warbird Gath'thong. In September of that year, the Gath'thong intercepted the Terran archaeologist for hire Jean-Luc Picard's ship, the Stargazer, in orbit of the Iconian homeworld in the Romulan Neutral Zone. Tebok demanded to know the reason behind the incursion. Telling him that his name was Galen, Picard claimed that he was conducting a routine scientific survey of the system.
