The logo for Mii

A Mii is a customizable character created by the player, used on Nintendo's video game consoles. Miis made their first appearance on the Wii when it was released. They also appear on the Nintendo 3DS, Wii U and Nintendo Switch consoles, and in some games for the Nintendo DS. Miis allow players to create a caricature of themselves, other people, or of invented characters. They are created in the Mii Channel on the Wii, in the Mii Maker on the 3DS and Wii U, and in system settings on the Nintendo Switch. The Nintendo DS does not have a way to make Miis on the console itself, but the games that use Miis include a Mii Maker to let players create them.
