On-screen appearance

Battle Entrances are a gimmick/feature in both the original Smash brothers and brawl (Not Melee). In short, a battle entrance is a short animation that each character has which plays out during the "3! 2! 1! Go!" part of the match. The idea is that everyone has a different way of arriving onto the stage.

Battle entrances have been confirmed to return to this installment of the game as shown in some E3 demo gameplay. Some entrances have also been confirmed but I will only include the newcomers' ones.
