CAPTAIN SULU ... I think I was another time...
Of Asian descent, Sulu served as helm officer on board the original U.S.S. Enterprise during one of its five-year missions, after an initial stint as an astrosciences physicist. He then was promoted to chief helmsman on board the U.S.S. Enterprise, under James T. Kirk.
In 2290, Sulu assumed command of the starship Excelsior and began a three-year mission charting gaseous anomalies in the Beta Quadrant. Because of this proximity to the Klingon Empire he was instrumental in saving the U.S.S. Enterprise from destruction by dissidents who were out to destroy the Khitomer peace conference.
