I feel like a Rampage monster (maybe Ralph, since he’s the more unique fella) would be perfect as a boss fight, and maybe an Assist Trophy too (like Rathalos). They’re definitely too big to be playable characters, that’s for sure.
But anyways, I wish Rampage could get this kind of special representation in Smash. It’s a very iconic and classic series with a fairly good history with Nintendo. Plus, I feel like pretty much everything of their games, from the arcade style of gameplay to the cartoony action and characters really feels like something Nintendo itself would totally do.
