Super crossover fighters

Jax, the cynical rabbit from The Amazing Digital Circus, finds himself abruptly thrust into the Crossover Realm, a twisted arena where universes collide. He is but one pawn in the malevolent 'Force of Shields'' grand game, a cosmic entity who has kidnapped iconic heroes and villains from worlds like Sonic, Mario, Cuphead, and Final Fantasy VII. Initially driven by self-preservation and a snarky indifference, Jax quickly learns that survival in this brutal dimension demands more than just his sarcastic wit. As he witnesses familiar faces battle unfamiliar threats, and reluctantly teams up with former rivals, Jax must confront his own cynicism. Can this unlikely alliance of video game legends overcome a power that dwarfs their individual might, or will they become mere spectacles in the ultimate multiversal gladiator match?
