Palette Swap (Super Smash Bros. Ultimate)

Palette Swaps in Super Smash Bros. Ultimate remain the same for the majority of the cast returning from the previous title, with each character receiving eight total. However, characters such as Mario and Cloud possess different outfits, while characters such as Robin, Corrin, and Byleth have male and female variants, and characters such as Bowser Jr., Olimar, Hero, and Steve change them into different characters that change their voice lines and name, though gameplay-wise they remain the same.

Unlike previous installments, palette swaps are now notated by "Color #."

In addition, by selecting the character on the character slot, an additional menu can be brought up to display all the colors immediately, though the traditional method of selecting a palette swap via the left and right shoulder buttons is still retained. Palette swaps are loaded up by order of the character's placement in the roster, meaning the characters from Smash 64 will have their palettes shown earlier than characters that are DLC.

• There is some costumes that have been cut and removed after 3DS/Wii U.
  • Mario: Wario colored, Fire Form & Jumpman colored.
