The next Super Smash Bros. title for the Switch 2 could feature a substantially revised roster, according to a Polygon article published July 27, 2026.

Super Smash Bros. games have historically updated their character lists to reflect recent Nintendo releases, using each new title as a snapshot of the company's current franchises.

The article suggested that the Mechanic from Splatoon Raiders might be added, providing a ranged fighter with multiple gadgets. It noted that Donkey Kong could receive a redesign inspired by Donkey Kong Bananza, including new attacks that involve breaking stage elements and a Final Smash featuring Pauline. The piece indicated that Samus Aran might gain new suit variants and a directed projectile based on Metroid Prime 4: Beyond. It also mentioned that Yoshi could obtain abilities from Yoshi and the Mysterious Book, such as throwing Peckadees or spreading spore effects. The article proposed that Tomodachi Life characters could replace Mii Fighters, allowing customizable avatars to appear as combatants. Additionally, it said that Karate Joe from Rhythm Heaven Groove might be introduced as a 2‑D fighter whose moves are synchronized with background music, and that Ditto from Pokémon Pokopia could be added as a shape‑shifting opponent.

Whether Nintendo will implement any of these changes remains unknown.
