Rick Sanchez has had his portal gun confiscated by the Council of Ricks, and the penalty for getting it back is humiliating: he must prove his worth by training and battling Mortys — an interdimensional surplus of alternate versions of his own grandson — in the Morty combat league. Rick does not look particularly bothered by this arrangement. Morty, as usual, did not really get a say. Across a vast multiverse of dimensions, Mortys can be captured, evolved, and hatched from eggs and gumball machines. The goal is to reach the top of the league and recover the portal gun.
