The fighting game series Super Smash Bros. from Nintendo, launched in 1999, and developed by Masahiro Sakurai, features an assortment of video game characters from different franchises. There are over 80 playable characters across the series, mostly sourced from Nintendo franchises but with a number of third-party ones as well. There are also other non-player character that take the form of enemies, bosses, and power-up.

Each game in the series has a number of playable characters, referred to as "fighters", that are taken primarily from Nintendo franchises. There are 83 total fighters across the series, with five additional downloadable content characters for Super Smash Bros. Ultimate still to be revealed. Starting with Super Smash Bros. Brawl, characters from non-Nintendo franchises began to make playable appearances. At the start of each game, some of the fighters will be locked from play. To unlock a hidden fighter, players need to clear certain conditions and defeat that fighter in a match. In Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate, players can make their own Mii Fighters that can be customized with three different fighting styles and costume pieces unlocked through gameplay or purchased as downloadable content. Several of these costumes are based on characters and franchises not otherwise represented, such as Heihachi Mishima from Tekken, Sans from Undertale, Cuphead from Cuphead, and Vault Boy from Fallout. All games have featured fighters that largely share their moves and abilities with another fighter on the roster, but with minor differences in their presentation and gameplay. In Ultimate, several of these characters were officially labeled as "Echo Fighters". They have an option to either be displayed next to or within the character portrait from which they are based on.

Notes

In addition to the roster of playable fighters, several non-playable characters appear as summonable items via "Assist Trophies" or Poké Balls, background stage hazards, enemies, collectibles, or bosses in the single-player modes. While some were specifically created for use in the Super Smash Bros. series, most come from established game franchises like the playable characters.
