Alternate costume (SSBB)

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 Marios, each one in different colors. Masahiro Sakurai referred to the implementation of costumes as "one of the joys of Smash".

Four of Peach's alternate costumes. Note that one resembles Daisy.

In Super Smash Bros. Brawl, players can pick different alternate costumes for their character by cycling through a list of up to six choices for a total of 222 costumes in the game. The buttons used to cycle are 1/2 for the Wii Remote and Nunchuk combination, A and B for the Wii remote alone configuration, and pressing X/Y for the Classic Controller and GameCube controller.

Most characters have six alternate costumes, though Jigglypuff, Lucario, Pokémon Trainer, and Sonic only have five, and Pikachu has only four. Wario has twelve costumes; two different outfits with six costumes each, doubling his options and giving him two different outfits for each team in Team Battles. Lucario, Pokémon Trainer, and Sonic have sets of alternate costumes that can be difficult to distinguish from each other in a match. As such, tournaments have the "colorblind rule" in doubles matches, where a player (colorblind or not) can choose which colours their team and their opponents' team are, if either team has one of the aforementioned characters on their team. While texture hacks are usually discouraged from being used in tournaments, if not flat-out disallowed, it is usually acceptable to use simple texture hacks on these characters to make the color difference between their team palettes more obvious.

When selecting characters in tournament mode, instead of displaying the character's colored image of the chosen costume, a colored bar is displayed in the player list. This color is usually an intuitive indicator of which costume has been chosen, but there are several cases where costumes are given strange colors, such as giving cyan to Ike's default blue-brown getup, or using orange or yellow when the opposite is clearly more correct.

In Wi-Fi, Tournament and Team Brawls, if two identical characters share the same alternate costume, the second character will have a lighter tint in their appearance. A third character on the same team uses a darker tint. The fourth character's tint is even darker than the third character's. It is generally quite difficult to distinguish from the third character's color scheme.

The order of the palette swaps for each character are sorted in the order in which they appear on the character selection screen.

Trivia

• Captain Falcon's red outfit actually has one file for each available PAL language in the game (English, French, German, Spanish, Italian). While presumably done so localizers could edit the "Blood Hawk" on the back to match the current language, this appears to have been skipped or glossed over, as there is no difference between the files.
• Mr. Game & Watch only has one file for his model and textures. This indicates that the color variations come from tinting or blending the textures, instead of pre-rendered bitmaps.
• Luigi has an unused blue costume in the game's data; this costume is slightly lighter in color than the used one, and the reason for its removal is unknown.
