Droid boxing

Droid boxing was an activity that involved sending two droids to duel in hand-to-hand combat. Aboard the Weequay pirate starship Marauder, Weequay pirates sent droids to box—one such droid being the modified ASP-series labor droid K0-5D. K0-5D's boxing skills earned him the nickname "Maximo."
