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; 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

This article is in need of additional images. The editor who added this tag suggests: Demo versions of Villager costumes, better image of the Ridley costumes, in-game model portraits. Comparison images would be ideal. If you have a good image for this article, upload it here.

Ridley's cut costumes.

• 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.
• 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.
