In order to get revenge, Stauz Czycz underwent a complete cyborg conversion, even altering his body in order to appear Human. Under the alias Awarru Tark, he became a bounty hunter. In 3 ABY, he was invited along with several other bounty hunters, to meet with Darth Vader about a bounty posting on Han Solo and Leia Organa.
"Tark" arrived late, and met with Vader alone on the Avenger. Once they were alone, he attacked Vader. Though Czycz was nearly a match for the Dark Lord, Vader extracted Czycz's true identity using the Force, then used telekinesis to shut down the bounty hunter's force field. Vader then killed Czycz with his lightsaber.
