Star Wars Episode 0: The Requel
Down an arm, out for vengeance
Left for dead in the night-cold sands of Tatooine, Rambo Calrissian was found by some of Guuda the Hutt’s goons. Guuda knew he would never lack for motivation, and so made a significant investment in repairing Rambo.
It’s always helpful to have a cyborg heavy driven by a need for vengeance.
