K0-5D began as a general purpose ASP droid, but has been extensively modified for gladiatorial combat. Fighting aboard the sparring pits of the Weequay pirate ship Marauder, K0-5D usually emerges triumphant, thanks to its powerful, steel-shredding servos and his integrated flame thrower. For his fighting prowess, the Weequays have taken to calling it "Maximo."
