A Sith trooper was a member of the Sith Lord Darth Krayt's Sith trooper army in 138 ABY. Highly sensitive to the Force, the trooper was physically augmented and improved by Krayt for decades beneath the surface of the planet Korriban and forged into an unquestionably loyal servant. In 138 ABY, Krayt ordered the trooper to commit suicide as a demonstration of the army's loyalty to two of his Sith Lords. The trooper ignited a lightsaber and died after being impaled beneath the chin.
Darth Krayt and his Sith Lords walk away from the trooper's corpse.
Decades before 138 ABY, a Force-sensitive individual was discovered by the Sith Lord Darth Krayt shortly after being born. Krayt gathered the individual and a number of other Force-sensitive infants and began to physically augment and improve them, forging them into extremely loyal and obedient Sith troopers deep beneath the surface of the planet Korriban. He kept the project secret from his One Sith Order, whose members he knew to harbor their own ambitions and desires.
By 138 ABY, the individual had become a Sith trooper in the Dark Lord's army. The trooper was in Korriban's catacombs, guarding the doors to a hangar full of Annihilator-class starfighters, as Krayt gave a tour of the project's facilities to Darth Nihl and Darth Talon, two of his most trusted Sith Lords. When Krayt ordered the trooper to commit suicide in a demonstration of the army's loyalty, the trooper immediately ignited a lightsaber and was impaled beneath the chin before falling over, dead.
The Sith trooper was highly sensitive to the Force and was physically augmented and improved by Darth Krayt for decades. Possessed of unquestionable loyalty and unquestioning obedience, the trooper followed Krayt's order to commit suicide without hesitation.
The Sith trooper appeared on a single page of the fifthieth and final issue of the Marvel comic-book series Star Wars: Legacy, which was written by John Ostrander, penciled by Jan Duursema, and released on August 18, 2010.
