Alternate costume (SSB4)
Each character in Super Smash Bros. 4 has a set of alternate costumes. Due to the presence of 8-Player Smash, all characters now have eight costumes (except for Little Mac, who has 16). Some costumes have slight visual differences between the 3DS and Wii U versions.
Some characters possess certain alternate costumes with more drastic design differences, and are not merely recolors of their standard outfits. Wario, Zero Suit Samus, Little Mac, Shulk, Cloud and Bayonetta have different outfits available; Villager, Wii Fit Trainer, Robin and Corrin all have male and female variants; 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.
Team Battles no longer confine characters to using their respective team color schemes, as teams are now indicated by colored outlines around the characters, giving players the freedom to pick whichever alternate costume they want to use in Team Battles.
On the Find Mii stage in Super Smash Bros. for Nintendo 3DS, the Dark Emperor uses magic that affects all players of the same color. Each alternate costume is allocated to one of the twelve Mii colors: black, brown, red, orange, yellow, light green, green, light blue, blue, purple, pink, and white. These colors are noted in the below lists as a bar underneath the corresponding portrait; as several characters have multiple costumes that share this color, the main color names as used on this page do not conform to this system.
Half of Bayonetta's costumes are based on her design from Bayonetta 2, while the other half are based on her design from Bayonetta. For the former half, she wields Love is Blue, which has blue attack trails. For the latter half, she wields Scarborough Fair, which has red attack trails, and speaks English even in the Japanese version.
Bowser Jr.'s alternate costumes replace him with each of the seven Koopalings. Bowser Jr. rides the Junior Clown Car which was introduced in New Super Mario Bros. Wii, whereas the Koopalings ride in a mass-produced Koopa Clown Car with a design unique to the Super Smash Bros..
Half of Cloud's costumes are based on his appearance in Final Fantasy VII, while the other half are based on his "Cloudy Wolf" design from Final Fantasy VII: Advent Children. In two of his Advent Childen costumes, his Geostigma-infected arm is covered by a sleeve, while it is exposed in the other two, revealing the red ribbon he wrapped around it in memory of Aerith Gainsborough. His costumes with the exposed arm are based on his appearance in Advent Children after his fight with Bahamut SIN, during which his sleeve is torn off.
Half of Corrin's costumes are male, while the other half are female.
Duck Hunt's alternate costumes change the dog and/or the duck's colors to resemble real variants of the respective animals.
Unlike previous games, none of Jigglypuff's alternate costumes change it to its Shiny coloration.
The color of his hammer does not change between costumes.
Little Mac is the only character with 16 different costumes, having a wireframe variant of each of his eight standard costumes. The wireframe variants are based on the player's appearance in the original arcade Punch-Out!! His wireframe palette swaps have slightly brighter cel-shaded colors than their non-wireframe counterparts.
Main article: Mii Costume
The Mii Fighters' various costume options are distinct from how other characters' alternate costumes work. The colors of these costumes match the Mii's original color from the Mii Maker. In addition, the Mii's original color is used in Find Mii. To view the Mii Fighters' alternate costumes, see here.

With the exception of her default and purple costumes, Rosalina's alternate costumes are complementary to Peach's and transitively may share some sources of inspiration. Additionally, there are six different colors of Luma outlined here, although the colors are not tied to Rosalina's costume.
With the exception of his first and last alternate costumes, all of Shulk's costumes are based on the color schemes of his party members from Xenoblade Chronicles.
Villager's appearance varies greatly between costumes, with differing eyes, hair, gender and clothing. All of Villager's alternate costumes, with the exception of the yellow costume, are based on how the player may look at the start of a new game depending on how they answer questions asked by Kapp'n or Rover in Animal Crossing: Wild World and Animal Crossing: City Folk respectively.
