The next joke character can't really be decided as easily as the other games. I mean, assuming "Joke character" refers to a character who really does not belong in the game because they're not normal fighters, then the list is huge. We have the mayor of a furry town, a dog, a robot packaged with the NES to boost sales, an exercise coach, a racer, two plumbers, a doctor (who we all know really isn't a doctor), and an astronaut fighting along side the king of evil, two gods, a starship pilot, a mercenary who can fight with and without power armor, a professional boxer, and an android with a little bit of the Borg built into his programming for good measure. And assuming "Joke character" is a character who's so bad anyone who plays them might as well kill themselves to end the match faster then we don't have any of those. So far all the characters are balanced enough to be viable in competitive battle. In melee, Pichu was the joke character. He was just terrible, and if you were good with him you were terrifying to face. Now, the characters all feel so balanced I don't see how any character could be considered a joke.
