Super Smash Bros Ultimate Fighters Pass is a downloadable content bundle for Super Smash Bros. Ultimate, granting access to the first wave of additional fighters released after the base game's launch. Each added character comes with a matching stage and music tracks tied to their home series.

As an expansion pass rather than a standalone game, it builds on Ultimate's core crossover fighting gameplay, letting owners of the base game unlock new characters for its extensive roster of single-player and multiplayer modes. It's aimed at players already invested in the main game who want its post-launch character lineup.
