Eh, there are a few characters in the game who are just n00b characters who anyone can play as. Namely:
Fox, Pit, Marth, Ike, Falco, and Lucas.
It would be nice if people learned to use favorites, but most people just take the easy route and use the characters anyone can be good with. This site is no exception, as it's full of spammers of those 6 characters.
