Alternate costume (SSBU)

NOTE: Every claimed source needs a cross-reference link; claimed sources need to be plausible, not awfully 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.

Each character in Super Smash Bros. Ultimate has a set of alternate costumes. Due to the presence of 8-Player Smash, all characters have at least eight costumes. Some characters possess certain alternate costumes with more drastic design differences, and are not merely recolors of their standard outfits. Mario, Wario, Link, Zero Suit Samus, Ike, Little Mac, Shulk, Cloud, Bayonetta, and Ridley have different outfits available; Pichu, Pikachu, Pokémon Trainer, Villager, Wii Fit Trainer, Robin, Corrin, and Inkling all have male and female variants; and Olimar and Bowser Jr. have model swaps that change them into new characters, complete with corresponding voice and Announcer clips, though like all other alternate costumes, they bear no gameplay differences.

Trivia

• In demo versions of Super Smash Bros. Ultimate, several characters had differences in their available costumes and associated portraits compared to the final game:
  • The Ice Climbers' character select portraits always showed Popo in front, although the stock icons changed to reflect which costumes let the player control Nana.
  • Two of Villager's alternate colors and one of Pokémon Trainer's alternate colors had a lighter skin tone compared to the versions used in the final game.
  • Ridley did not have his Meta Ridley costumes available; instead, two palette swaps were present that used the same colors as the Meta Ridley costumes. These costumes are not used in the final game.
  • Mario, Link, Pikachu and Villager used images of their in-game models for character select portraits instead of their official renders.
  • Sonic's 4th alternate costume used a pale blue shade of fur rather than white fur like in the previous game. This was changed back for the final release of the game.
• Some costumes that were shared through pre-release screenshots on the Ultimate site are slightly different than from their appearances in the final build.
  • On Luigi's purple costume, the "L" on his cap was green in screenshots but is purple in the final build.
  • On Wario's yellow overall costume, the buttons on his suspenders were gold in screenshots but are white in the final build.
  • On Wolf's default costume, his jacket and gloves are dark purple, the straps behind his right shin guard are white, and the soles of his boots are red compared to his color scheme in the final build.
• Ultimate is the first game where every character has the same amount of alternate costumes, 8. This does not include Pokémon Trainer having multiple costumes per player, or Mii Fighter costumes.
