Zank Helrott was a human bounty hunter, identified as male, who during the Cold War era (a conflict between the Galactic Republic and the reconstructed Sith Empire) worked for Rogun the Butcher. He was known for always bringing in bounties deceased, not alive. Rogun tasked him with locating Ace on Nar Shaddaa, with instructions to return the smuggler to him dismembered. He tried to seize the smuggler on Drooga's pleasure barge, but Bowdaar, a wookiee, intervened, reciprocating a previous act of assistance where the smuggler aided him against Kaleesh warriors. The ensuing conflict resulted in Zank's death, which amused Drooga.
