Mii

"This game's mine!"

- Mii

Miis are the digital avatars that appear in the Mii Plaza from one of the Wii Channels. Miis are based off of human beings and players can design what their Miis look like so then the player can use them. Players can start from scratch or make an existing Mii into Miis. Only 100 Miis fit in one Wii, while the Wii Remote itself can hold 10 Miis.

WarioWare: Smooth Moves
Miis have first appeared with Wario in WarioWare: Smooth Moves. In this game, the Miis star in multiplayer mode and in a few of the microgames. Players must also use Miis to personalize their own files. One of the multiplayer modes starring the Miis is very similar to the mini-game Balloon Bang.

Mario Party 8
In Mario Party 8 they are playable characters in the Extra Zone and are sometimes seen in the background of mini-games. The Miis in this game however wear overalls, gloves, and shoes like the Mario Bros. Miis are also available to personalize players' files.

Mario & Sonic at the Olympic Games
In Mario & Sonic at the Olympic Games, Miis are playable characters, just as capable of competing as the characters from the Mario and Sonic series. Their stats are all five out of ten.

Mario Kart Wii
In Mario Kart Wii, Miis first appear as background characters found in various race courses. They also appear in posters and other signs, as seen in Coconut Mall. Later in the game, Miis can be unlocked as playable characters. There are two outfits available for Miis and both outfits have to be unlocked. The first one is a plain racing suit of the player Mii's favorite color and the other one depends on what gender the Mii is. If the Mii is male, he receives a Mario outfit, but if the Mii is female, she receives a Princess Peach outfit.

A kart color may also change depending on the Mii's gender (blue for males, pink for females). Miis also receive a voice, for the first time, not counting Wii Play where they briefly made a cheering noise after the Shooting Range event-their voice depends on their size, for example if it's a tiny Mii it will have a tiny childish voice and a heavy Mii will have a deeper more mature voice. The weight class for the Mii driver depends on the size the Mii is in the Mii Channel. Height class depends on the height of the Mii, left side is light, middle is medium, and right is heavy. Notably, when the player plays as a Mii, statues and pictures in various courses, such as Moonview Highway, Coconut Mall, and Daisy Circuit, will replace the character heads with that of Mii heads, consisting of the Miis saved on a players Wii console.

A Mii can be either a large, medium, or lightweight character, depending on its height and weight. In Mario Kart Wii, even if a Mii is really tall, but doesn't weigh a lot, it will still be categorized as a large character. Unless it's skinny. It'll be medium then.

Dr. Mario & Germ Buster
In Dr. Mario & Germ Buster, Miis are able to replace Dr. Mario as the playable character. Here they must maneuver Megavitamins tossed into a glass jar in order to destroy the Viruses. In order for a virus to be destroyed, it must be connected to at least one Megavitamin of the same color. Unlike Doctor Mario, Miis speak.

Mario Super Sluggers
Miis are playable characters in the game Mario Super Sluggers. Mii's can't be chosen as captains, but it seems as though that up to 8 Mii's can be used. Miis in Mario Super Sluggers have wooden bodies with painted on baseball uniforms. Miis have 6/10 on all stats and chemistry to characters matching their colors, example. Red has chemistry with Mario and green has chemistry with Luigi and pink for Peach etc. Also Miis of the same color have chemistry.

It should also be noted that all male Miis are right-handed batters, while the female Miis are left-handed batters in this game. Both genders are right-handed fielders though. For some reason, they don't speak in the game.

Mario & Sonic at the Olympic Winter Games
Miis return in Mario & Sonic at the Olympic Winter Games. This time, Miis can be customized to wear different clothes and accessories. Unlike the last game, the stats differ depending on the gear. They can even wear different costumes of the playable characters in the game.

Non-Playable Appearances
Miis also appear in games such as Donkey Kong Barrel Blast, and Mario Strikers Charged Football to represent the player, similar to an avatar. In Super Mario Galaxy, players can personalize their files with Miis. This has also been done with other non-Mario related games. In Super Smash Bros. Brawl, the player can use their Mii on Wi-fi to represent themselves.

Check Mii Out Channel/Mii Contest Channel
One of the channels in the Nintendo Wii is the Check Mii Out Channel (or the Mii contest channel), where Nintendo holds contests to see who can create the Mii that looks the most like a certain person, for example a few contests had players to create Miis that looked like the Tooth Fairy, or another that even had players to create a Mii of a Gingerbread Man. Some of the contests have been Mario related. Here is a list of them:
 * Mario, without his hat, was the first contests in the Check Mii Out Channel.
 * Luigi, without his hat, was another later contest.
 * Another contest had players create Princess Peach.

Trivia

 * The name Mii is the portmanteau (a word formed by joining two others and combining their meanings) of "me" and "Wii."
 * Nintendo's head developer, Shigeru Miyamoto had wanted to create Miis since the NES, and kept trying to create them with mostly every system Nintedo could such as the Nintendo 64DD add-on and Nintendo DS.
 * A face editor was used for creating passports in the game Mario Party Advance, sharing similarities with the Mii concept, but it is unknown if this contributed to the development of Miis.
 * In the Mii Channel, when the player presses the arrange button, it has the same whistle pattern as Captain Olimar's whistle. (A short one followed by a long one), same as when undone, (3 short ones).
