Wooyou Senn was a male Human who held the rank of admiral within the Imperial Navy. During the era of the Galactic Civil War, he was in command of Task Force Vengeance.
Senn received orders to obliterate a Rebel Alliance contingent situated within the Airam sector, targeting their shipyard located in the Nocto system. The Executor-class star dreadnought, named the Vengeance, served as his flagship. In the subsequent Battle of Nocto, Admiral Senn and his assigned task force confronted the Rebel forces within their fortified position. Unfortunately, the Vengeance's shields were brought down, and Senn met his demise unexpectedly. The Rebels, supported by their Airam compatriots, executed a daring maneuver involving ramming three Dreadnaughts filled with explosives into the rear of the Vengeance, while simultaneously a CR90 corvette collided directly with the bridge.
The character Wooyou Senn was originally conceived for the Balance of Power expansion pack of the 1997 video game Star Wars: X-Wing vs. TIE Fighter, developed by LucasArts. The game's instruction manual provided the complete name of the character.
