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.

Inkling male and female alternate costumes.

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.
