Sully Tigereye, a Trunsk, formerly served as an Elite Commando infiltrator unit member within the New Republic under the direct command of Colonel Andrephan Stormcaller; he later accompanied Stormcaller to the Red Moons mercenary group. A past experience, potentially predating his New Republic service, involved imprisonment and possible enslavement, which drove his decision to join Red Moon.
Leading a mercenary squad, he undertook the mission to liberate the children of a businessman seeking defection from the Pentastar Alignment to the New Republic. During this operation on Gabredor III, he engaged in close combat with the Defel named Vex, ultimately killing him.
The news of his close companion, Lex Kempo's, passing brought him sorrow.
Alongside Stormcaller, Ivey, and Hugo Cutter, he was in Nexus City on Entralla, where they were formulating a plan to disrupt the Lunar Night celebrations.
