Oh comeon now. Its a fantasy game, Im pretty sure any character can win any event.
Just like all these people complaining about Olimar being in Smash, sure in his own game hes the size of a quarter, but remember the past smash titles, these are either dolls/trophies who are fighting each other.
Remember its just fantasy, its the best gamer whho knows who to play who will win, just like in the preview of Sonic entering smash,
he kicked marios butt, but yet mario is a smash veteran
