Palette Swap (Super Smash Bros.)

In Super Smash Bros., each character had at least four costumes, one for each of the costume changing C buttons. Some characters had an extra costume or two, to accommodate for Team Battles if their four costumes lacked a red, blue, or green variation, these costumes cannot be selected outside of Team Battle since there are only four C buttons.

• There are 6 fighters with only 4 color swaps, and 4 fighters with only 5.
• In the files, there are unused stock icons for Pikachu wearing a yellow party hat and Jigglypuff wearing a yellow bow.
• Fox's alternate costumes were supposed to be his teammates from Star Fox and Star Fox 64: Falco Lombardi, Slippy Toad and Peppy Hare.
