Mii

A Mii is a digital avatar for the Wii's Mii Channel. After the player creates them, they can be used as participating characters in certain Mii-oriented games, as first shown in Wii Sports, Wii Fit, and Wii Play. Miis are customizable and allow the user to capture a likeness or caricature, or capture the personality of themselves and others.

Up to 100 Miis may be created on any Wii console. The Wii Remote itself can hold up to 10 Miis on its internal memory, which can later be transferred to another Wii console. In addition, Miis can also be exchanged via the WiiConnect24 service, whereby allowing a player's Miis to "Mingle" will enable such Miis to appear on other people's Wii consoles (appearing in a "Mii Parade", where up to 10,000 may feature). Users can also transfer Miis to supported Nintendo DS games. Miis can only be edited on the console on which they were created.

Metroid Prime 3: Corru[tion requires Miis to be used to identify Save files. 6 are pre-loaded into the game, and will appear whether or not any Miis exist on the Wii. Copying a file keeps the Mii with it. If the Mii representing the file is deleted or removed from the Wii's memory, the game will require the player to select a new one before continuing. It will later appear in Samus Aran's Gunship if the player activates the Mii Bobblehead unlockable.
