3999. Lieutenant Hikaru Sulu

Hikaru Sulu is a character in the Star Trek media franchise. First portrayed by George Takei in the original Star Trek series, Sulu also appears in the animated Star Trek series, the first six Star Trek movies, one episode of Star Trek: Voyager, and in numerous books, comics, and video games. John Cho assumed the role of the character in the 2009 film Star Trek.

The fictional character Hikaru Sulu was born in San Francisco, and is of Japanese heritage. He was shown as the USS Enterprise's staff physicist in the pilot episode, "Where No Man Has Gone Before", but served as helmsman throughout the rest of the series, during which he held the rank of lieutenant.
Throughout the series, Sulu is shown having many interests and hobbies, including gymnastics, botany, fencing, and ancient weaponry. In the episode "The Naked Time", Spock observes that Sulu "is at heart a swashbuckler out of the 18th century".
The character is promoted to lieutenant commander some time before Star Trek: The Motion Picture, and to full commander by the time of Star Trek II: The Wrath of Khan. During the first five Star Trek movies, he serves as helmsman aboard both the USS Enterprise and USS Enterprise-A. He is promoted to captain and given command of the USS Excelsior three years before the events of Star Trek VI: The Undiscovered Country.
Star Trek Generations introduces Hikaru's daughter, Demora Sulu, whose origins are also depicted in Peter David's non-canon novel The Captain's Daughter.
