To get right to it, something is going wrong with attempts to play Super Smash Bros. Ultimate online using Switch 2 systems.

The problem might occur when a player attempts to use one character in specific: the Mii Fighter.

In SSBU, the Mii Fighter is a customizable character. In fact, you can use a Mii that is associated with your Nintendo account. This gives the character a personal element.

So, what’s the problem? When a player with a Switch 2 attempts to use a Mii Fighter in an online match, the match might immediately end. Why? I’m not sure, but it might have to do with a change to the customization options for the Mii avatars so players can no longer choose a gender for them.

Nintendo has given a provisional solution to the issue to players: by asking players to refrain from using the Mii Fighter in online matches.

Perhaps Nintendo is working on a patch. It’s hard to imagine that they’d want to leave things as they are.

As I see it, if the problem is with the change to the Mii customization option, that’s the problem to address, preferably by reverting to allowing for the option to pick between male and female. The issue shouldn’t be with Super Smash Bros. Ultimate, considering that it worked online just fine on Switch prior to the launch of Switch 2.

If messing with the gender choices of the avatars is what’s causing the issue, it sounds like another example of messing with something that shouldn’t have been messed with, resulting in undesirable consequences.

Recent attempts to blur the distinctions between the sexes in competitive sports comes to mind.
