How do I restore a default Mii Fighter?

When Mii Fighters are unlocked in World of Light, the game will provide default Miis that match the character select icons. However, while creating Mii Fighters with my friends, we accidentally deleted the default Mii Swordfighter.

How can I restore the default Mii Swordfighter after accidentally deleting it?

Solution 1:

You can't "restore" a deleted Mii Fighter, but you can create one that matches the defaults. If you create a new Mii Fighter, and leave all of the selections the default setting (e.g. don't change any of the costume settings or any of the move selections) you'll have the equivalent of the default generated Mii Fighter. I can't remember which Mii template each fighter uses, but it is one of the default templates rather than one you would have to generate.
