If you’re like most people, you probably have a Wii U with the console itself and not a GamePad. If you don’t, you can use the Wii U’s online service to delete Mii characters. To do this, go to the Wii U’s main menu and select “System Settings.” Then select “Game & System.” In the Game & System section, select “Mii Menu.” In the Mii Menu, select “Delete Mii Characters.” After selecting this option, your Wii U will ask for your Nintendo account password. Once you’ve entered your password, your Wii U will delete all of your Mii characters.
