This story's creation is credited to Lovern Kindzierski as the writer, Robert Teranishi for the pencil work, Vickie Williams for the lettering, and Dave McCaig for the coloring. The events of the story unfold in the year 3 ABY.
Responding to Darth Vader's summons for bounty hunters to locate the Millennium Falcon, Awarru Tark appears on the Star Destroyer known as the Avenger, piloting a YT-1300 freighter. Upon encountering Vader, he immediately initiates a fierce attack against the Sith Lord, utilizing grenades and light blades that protrude from his arms.
Vader delves into Tark's thoughts and discovers that Awarru Tark is, in reality, Stauz Czycz. Czycz had undergone a surgical procedure to embed a force field generator within his body. This was done so he could exact revenge on Vader for the loss of his family during an Imperial attack on his planet.
Employing telekinesis, Vader neutralizes the generator and subsequently decapitates Czycz. He then reflects on Czycz's transformation, musing on the fact that he had become more machine than man.
