TR-522

After the Battle of Yavin, stormtrooper TR-522 was stationed on the planet Dathomir. He was based in a small forward post that was part of the defensive system of the secret Imperial Research and Prison Facility. TR-522 used to wear a black Imperial Spec Ops Officer armor.

In 1 ABY, an accident took place in the Imperial Research and Prison Facility. The Blackwing virus that was studied there escaped containment and decimated most of the people in the area, turning them into starving undead creatures. In TR-522's forward post, all the stormtroopers stationed there during the outbreak were infected and turned into zombies. Only TR-522 appeared to be immunized to the virus and barely escaped the undeads by fighting his former fellow strormtroopers with his stun baton.

In response, the Galactic Empire promptly established a Quarantine Zone to contain the infection. The few people who survived the initial virus outbreak, including TR-522, were trapped in the Quarantine Zone. The survivors established camps in order to to repel the regular assaults of the zombies and try to live in safety while waiting for an evacuation. TR-522 took shelter in Camp Delta, his former forward post, along with Imperial Lieutenant Erlem Marh and the Bothan Oona Wran.

Later, a spacer arrived at Camp Delta and delivered a radio to TR-522. The radio was provided by the Imperial pilot Jeb Maris in Camp Alpha who had decided to establish communications between the camps. Once radios were delivered to the five camps in the Quarantine Zone, the survivors were able to safely coordinate high altitude supply drops sent from outside the Quarantine Zone.

TR-522 was a non-player character in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011. TR-522 was added to the game with the "Game Update 14," a.k.a. the "Death Troopers" update, released on October 12, 2009.
