In 1 ABY, a unit of Triumphant-class dark troopers escorted Darth Vader aboard his shuttle ST 321 during the operations Molecular Clamp, Sieve, Lumberjack, Overlord, Green Light, Take Down, Clenched Fist, and Dark Glory in the cities of Bestine on Tatooine, Coronet City on Corellia, and Theed on Naboo. During the Empire Day in 1 ABY, two Triumphant-class dark troopers were deployed to escort the Imperial enforcer, Darth Vader, to the festivities in Theed in order to present loyal personnel with various awards.
In Star Wars Galaxies, Darth Vader, his shuttle, and several of these dark troopers appear in one of the three cities at erratic time intervals. Players of the Imperial faction can talk to Vader to receive four consecutive quests that consist of killing Rebel Non-Player Characters and players. Two Triumphant-class dark troopers were found during the Empire Day events. Although they were sometimes referred to as BCP-53 and BCP-62, these were actually the result of random name generators in the game, with their true designations being unknown.
It is not known whether these dark troopers are droids or living beings. As with all dark trooper variants in Star Wars Galaxies, they do not use their jetpack or assault cannons.
