Characters in the Super Smash Bros. series
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".
