Nintendo Issues Temporary Ban on Mii Fighters in Super Smash Bros. Ultimate Due to Compatibility Glitch with Switch 2

Major Compatibility Issue Disrupting Super Smash Bros. Ultimate on Switch 2

Nintendo has recently updated its list of known issues affecting the new Switch 2 console, specifically highlighting a problem with the popular fighting game, Super Smash Bros. Ultimate. The company is advising players to temporarily refrain from using the Mii Fighter characters until a fix is implemented.

What’s Causing the Disruption?

According to Nintendo’s support website in Japan (with insights shared by gaming analyst OatmealDome), the issue arises exclusively during online matches involving players on different consoles—one on the original Switch, and the other on Switch 2. When a player selects a Mii Fighter in such multiplayer sessions, the game risks ending the match abruptly, often kicking both players out unexpectedly before any combat occurs.

Impact on Gameplay and Player Experience

This glitch can cause matches to terminate immediately if a Mii Fighter is involved, disrupting the gameplay and frustrating players eager to compete online. Nintendo has not yet disclosed the underlying cause of this problem, but the fact that it affects only Mii Fighters suggests a possible compatibility issue related to how the newer console handles custom avatars and character data.

Additional Concerns for Mii Fighters

Beyond match disruptions, Nintendo also warns that thumbnails for Mii Fighters may not save correctly on Switch 2, indicating further compatibility challenges with these custom characters. The company has assured fans that a software update is in development to address these issues, but no release date has been announced yet.

Background on Super Smash Bros. Ultimate

Originally launched in December 2018, Super Smash Bros. Ultimate remains one of Nintendo’s best-selling titles, with over 36 million copies sold worldwide. Its extensive roster of characters and ongoing content updates have solidified its status as a definitive entry in the series—hence the ‘Ultimate’ moniker. Fans are now eager to see what Nintendo has planned next for the franchise.

Upcoming Projects and Future Releases

Recently, Nintendo revealed that series director Masahiro Sakurai is working on a new project called Kirby Air Riders. Unlike a new Smash Bros. installment, this game will feature Nintendo’s beloved pink puffball and is scheduled to launch later in 2025 exclusively for Switch 2.

Stay Tuned for Updates

As Nintendo works to resolve the Mii Fighter compatibility issues, players are encouraged to stay updated for the upcoming patch. In the meantime, it’s advisable to avoid selecting Mii Fighters during online matches on Switch 2 to prevent unexpected disconnections and game disruptions.
