An Andorian Starfleet officer who served as Janeway's first officer aboard the Dauntless and later Voyager-A.
Tysess is an Andorian Starfleet officer, voiced by Daveed Diggs. He served as first officer of the USS Dauntless under Vice Admiral Kathryn Janeway during her search for the missing USS Protostar and its young crew, a mission on which the Vau N'Akat infiltrator Asencia was also aboard in disguise.
When Janeway took command of the USS Voyager-A in the second season, Tysess continued as her first officer, serving alongside the Protostar cadets as they trained aboard the ship.
