Mario Tennis Fever: 38 playable characters in the most ambitious game of the series

Nintendo is continuing to strengthen the Switch 2 lineup, this time turning to sports with the announcement of Mario Tennis Fever, a brand-new entry in the iconic franchise coming exclusively to the console. This installment promises to be a major milestone for the series, thanks to its massive roster: 38 playable characters, the largest selection ever in a Mario Tennis game.

Since its debut on the Nintendo 64, the Mario Tennis series has consistently combined accessibility, fun, and competition. With Mario Tennis Fever, Nintendo is raising the stakes by introducing an unprecedentedly diverse cast. The timeless staples Mario, Luigi, Peach, Daisy, Bowser, Yoshi, and Donkey Kong are all included, but they’ll be joined by less expected faces like Rosalina, Pauline, Kamek, and Boom Boom. Even rarely playable characters from Mario spin-offs are making their debut, bringing true variety to playstyles. Each character will feature unique stats and a distinctive style, balancing power, speed, or technique for matches that are as strategic as they are spectacular.

But Nintendo isn’t just expanding the roster: Mario Tennis Fever brings major gameplay innovations. The new Fever Shots make their debut special moves unique to each character that can completely change the flow of a match. Courts are now more interactive, with environmental elements spicing up rallies and forcing players to adapt on the fly. On the multiplayer side, both local and online play support up to four players simultaneously, with matchmaking improved thanks to the more robust infrastructure of the Switch 2.

Nintendo also promises a wealth of content for every type of player. Classic singles and doubles matches return, but the game also introduces an Adventure Mode designed as a true solo challenge. Players will face off against original bosses, overcome varied scenarios, and progress through a light RPG-style story. Finally, the “World Tournament” mode allows players to compete online against opponents worldwide, featuring seasonal rankings and leaderboards to keep the competition alive long-term.

With its 38 characters, fresh mechanics, and an optimized presentation that takes full advantage of the Switch 2’s power, Mario Tennis Fever is shaping up to be one of the flagship titles of 2026. Nintendo continues to expand its catalog, showing once again that its console aims to appeal to both families seeking fun and competitive-minded players.
