In "Super Smash Bros. for Nintendo 3DS" and "Wii U" and "Super Smash Bros.Ultimate", players can make their own Mii Fighters. Mii Fighters have costumes which can be unlocked or bought as downloadable content. Many of these costumes are based on characters and series which do not have playable characters, such as Heihachi Mishima from "Tekken", Sans from "Undertale", Cuphead from "Cuphead", Vault Boy from "Fallout" and Travis Touchdown from "No More Heroes". All games have fighters that share a lot of moves and properties with other characters, but with some small differences. In "Ultimate", these characters are called "Echo Fighters".
