What I really want:
Amaterasu - pretty much impossible as a somewhat irrelevant third-party character from a game that never sold well.
Impa - would be cool as an echo of Sheik for more Zelda representativity. They said no echoes, though.
Rex - sounds weird that it's the Mii costume you get for buying the DLC, probably a sort of promise.
Steve - it's possible but please for the love of god no.
What's wrong with Rayman in Smash?
Some days I just blow up.
