Sulu

Hikaru SuIu. Almost as little is known about Sulu, although he did at least get a first name (Hikaru) in Star Trek VI, and his hometown was established as San Francisco in Star Trek IV He had at least one child, Demora Sulu, who was a helm officer on the first voyage of the Enterprise-B in Star Trek Generations. In the 24th century, Sulu's portrait hung in Starfleet Headquarters, mentioned by Janeway in "Flashback" (VGR), although we don't know what specific thing he did to earn this recognition. It is possible that Hikaru Sulu recommended young Chakotay for admission to Starfleet Academy in 2350 ("Tattoo" [VGR]), although it is not clear if this was Hikaru or some other Captain Sulu. We speculate Sulu was 29 at the time of Star Trek's first season, suggesting a birth date of 2237. Hikaru Sulu would have been 113 years old at the time Chakotay applied for the academy.
