I think you have to be nominated first & it has to be approved, then voted on. But other characters, have appeared in games before, most sports (NBA Jam) or fighting games (SoulCaliber), although they're usually animated like Yoda, etc. None for Super Smash series though.

Although it would be nice to have a custom character option in Smash Bros to make your own character. Or even be able to add sprites, much like logos added in Mario Kart series. You could punch Justin Bieber & other celebrities then.
