Tyrix held the rank of commander within the Imperial Army, stationed at the garrison located on Vryssa. His three decades of service within the military potentially indicate that he was a veteran who participated in the Clone Wars.
Boba Fett brought about his demise after General Gaege Xarran, Tyrix's commanding officer, provided sanctuary within the base to Rivo, his brother, who was being pursued by the bounty hunter.
When Fett was thought to have perished in a chemtrox gas assault, Tyrix was unexpectedly struck by a blaster shot, leading to his death.
