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. While the Nintendo DS does not have Miis as a part of the console itself, some games (such as Tomodachi Collection) have Miis built into them. 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. Once the player creates a Mii, they can use it in some of Nintendo's video games.
