Mario Tennis Fever is an upcoming multiplayer sports game in the Mario Tennis series set to be released worldwide for the Nintendo Switch 2 on February 12, 2026 as part of the Super Mario Bros. 40th Anniversary celebration. First announced during the September 2025 Nintendo Direct, it is the ninth installment in the Mario Tennis series, and the first Mario sports game to be released on the Nintendo Switch 2. The gameplay elements are similar to those of Mario Tennis Aces, but the game introduces new features, including Fever Rackets. Each Fever Racket has its own special abilities, creating unique effects on the court. Players can build up their Fever Gauge during rallies, allowing them to use new tactics with Fever Shots. The game will incorporate elements from Super Mario Bros. Wonder in modes such as the Tournament and Mix It Up.

Additionally, the game will feature a story mode in which Mario and others are transformed into babies by monsters encountered on a remote island. Having lost their tennis skills, the babies must learn to play tennis from scratch and defeat the monsters to return to their original forms.

The game will also offer expanded online feature modes.

Characters

Playable

The game is confirmed to have 38 playable characters, surpassing Mario Tennis: Power Tour for the most of any game in the series.[1] The following characters have been confirmed:

Babies

Some characters transform into babies during the Adventure mode. Among them, this game marks Baby Luigi's debut in the Mario Tennis series (excluding his cameo in the intro cutscene for Mario Power Tennis and being playable in Mario Sports Superstars), Baby Wario's first appearance in a home console game and his first appearance overall since Dr. Mario World, and Baby Waluigi's[conjectural] first appearance overall. While it is known that Baby Mario is playable during the Adventure mode, it is currently unknown if the other babies are, as well as if any of them are part of the main playable roster in other modes.[1]
