Ballmastrz: 9009

From the creator of Superjail! comes Ballmastrz: 9009, a 2018 show on [adult swim] that takes place in the dystopian future of 9009, taking place years after the Rad Wars. To end the war a mysterious being known as Crayzar created The Game, where teams use sentient balls to score and kill each other. This brings us to the present, where the worst team known as the Leptons lead by Ace Ambling face against the greatest team, the Boom Boom Babies and their star player Gaz Digzy, whom Ace idolizes.
