Palette Swap (Super Smash Bros. Ultimate)

The Palette Swaps in Super Smash Bros. Ultimate was pretty much almost unchanged from its predecessor, except some of the characters has brand new alternate costumes when selected on the Character Selection Screen, replacing some of them.

Inkling
Inkling alternates between a female and male version, each with their respective default haircut from the first Splatoon.

Ryu
All of Ryu's costumes are based on his alternate costumes from Super Street Fighter II and the Turbo HD Remix.

Snake
Most of these are based on different camouflage suits worn by Naked Snake (a.k.a. Big Boss) in Metal Gear Solid 3: Snake Eater.

Villager
Villager's appearance varies greatly between costumes, with their eyes, hair, gender and clothing all changing. 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. The shirts/dresses worn are named below.
