fictional character from Star Trek
Tuvok is a fictional character in the Star Trek media franchise. One of the main characters on the television series Star Trek: Voyager, Tuvok is a member of the fictional Vulcan species who serves as the ship's second officer, Chief of Security, and Chief Tactical Officer. Tim Russ portrayed Tuvok throughout the show's run from 1995 to 2001, and has also been involved in subsequent portrayals.
Tuvok's backstory is that, up to the time of the first episode, Caretaker, he was working as an undercover Federation agent in a Maquis group led by Chakotay aboard the Maquis ship the Val Jean. His recovery is the mission Voyager is sent on, a mission that is completed by Janeway at the cost of about one third of her crew and seven years in space, creating the basic setting of the series.
