Tuuk was a Tellarite person of the 24th century and a mercenary in the Silver Paladin's band.
Tuuk's mate was Gerva.
In 2364, Tuuk, Gerva, and the rest of the organization were based at Rikan's castle, Warrior's Rest, on the planet Treva, where they aided the rebellion against President Nalavia. The two Tellarites and Barb bought parts to construct false containers in the team's plot to replace the Riatine drug with a placebo. When Nalavia's forces later assaulted the castle in response, Tuuk and Gerva helped defend its walls against flyers and fight off her soldiers, and later flew a flyer against their air forces.
