Alternate costume (SSBM)

NOTE: Every claimed source needs a cross-reference link; claimed sources need to be plausible, not horrendously obscure; default costumes usually don't need descriptions since they are not alternate costumes; returning costumes original to Smash do not need references to their appearances in previous Smash games.

A battle between four Dr. Marios, each one in different colored lab coats.

Super Smash Bros. Melee added additional alternate costume options to characters by using the X and Y buttons to cycle through the available list instead of using four C buttons to pick a specific color; this removes the limit as to how many are selectable, so there are no longer any costumes exclusive to Team Battles or computer opponents. As a result, many characters now have five different color schemes, with some having as many as six, though some still only have four.

When selecting characters in tournament mode, instead of displaying the character's colored image of the chosen costume, the character's name is given a tint and a colored bar is displayed in the player list. This color is usually an intuitive indicator of which costume has been chosen (with no color denoting default), but there are some that are slightly unusual (such as Luigi and Peach's white costumes that are denoted by a grey).

In Team Battle, if members of the same team use the same character, the second player would have a lighter tint applied to their character. A third player uses a darker tint. If a fourth player is forcibly added to a team with the Name Entry glitch, then the fourth character will be completely black; the game's data suggests that a fifth player, if possible, would be completely grey. A sixth player and afterward, would crash the game.

Strangely enough, alternate costumes can affect gameplay, such as Captain Falcon's model changing sizes depending on the costume.
