[King Hadas]

Oh god, I hope Ash Ketchum is a playable character.

EDIT: Oh man, Nintendo needs to make some sort of contest for coming up with characters for this game. I was looking around after Darkvare mentioned the next Smash bros and people are getting really creative with ideas for this game, here's the wackiest I've seen so far.

Shigeru Miyamoto
The guy from exitebike
Old man
Andross (the guy explained it as being some time in the Star fox universe before he turned into the giant floating head)
Laughing Dog from the Duck Hunt game.
