Mii

Miis are digital avatars that appear in the Mii Channel, Mii Maker, StreetPass Mii Plaza, Miiverse, and various other Mii-centered games and applications in Nintendo consoles, starting with the Wii. Miis get their name from how the word "me" would be written in rōmaji, in the same way that "Wii" is derived from a similar spelling of "we." Miis are based on humans, and players can design the appearance of their Miis look like and use them in compatible games. Not counting factory-installed software in Nintendo consoles, Miis first appear in the game Wii Sports.

Shigeru Miyamoto had wanted to create digital avatars for Nintendo consoles since the Nintendo Entertainment System and kept trying to create them with every system released, such as the Nintendo 64DD add-on and Nintendo DS.

Players can start from scratch or create a Mii from an existing template Mii. Only 100 Miis fit into one Wii, while each individual Wii Remote can hold ten Miis. Miis can also be created on the Nintendo 3DS, Wii U, and the Nintendo Switch, as well as through the smartphone application Miitomo. Miis can be created either from scratch or from a photo, using Mii Maker, where they can be edited as well. Also, Miis can be made into QR Codes, to be scanned from another Nintendo 3DS, or a Wii U. Each 3DS and Switch system can have up to 100 Miis, and each Wii U system can have up to 3,000 Miis.

One of the channels on the Wii is the Check Mii Out Channel (Mii Contest Channel in PAL releases), where Nintendo held contests for participants to create a Mii resembling a certain person or character.

On May 24, 2018, Nintendo introduced a browser-based Mii editor called Mii Studio. The editor is available for all Nintendo Account/My Nintendo users in all regions. Mii Studio supports all Mii attributes and standards introduced for the Nintendo Switch. Up to six Mii avatars can be created at a time, including any Mii imported from a linked Nintendo Network ID.

Wii Sports
Miis are playable characters in Wii Sports. If the player has not yet created a Mii, they instead have to play as one of the game's default Miis.

Check Mii Out Channel
The Check Mii Out Channel featured Nintendo holding contests to see who can create the Mii that most closely resembles a certain person or character. For example, a few contests had players create Miis who looked like the Tooth Fairy or a Gingerbread Man. The very first contest was to create a Mii of Mario without his cap.

Mii Settings
The player can put the nickname of the Mii, the gender, birthday, favorite color, Mingle, Mii Creator and if it is a favorite.

If the player chooses "Favorite" then this Mii is grouped separately from the normal Miis. The player can choose if they want that Mii to be "Mingle". This will make the Mii appear in other people's Wiis. However the player must have Internet connected to the Wii.

When the player chooses the favorite color of the Mii, the shirt/dress (depending on the gender) will turn that color. The player can lie about the favorite color and change the color of the shirt to a color that's not the Mii's favorite color.

Body Shape
In the "Body Shape" section, the player will be able to decide if the Mii is short or tall, thin or fat.

Facial Features
Here players will be able to decide how the face if the Mii will look. If it will be a circle, or if the chin is a triangle ect. The players can also choose how dark the skin is.

The player can also add freckles, makeup, dimples, old age wrinkles ect. in this section.

Hairstyle
Players can choose 72 different kinds of hairstyles for their Mii. Also, players can change the color of the hair (Black, brown, red, orange ect.)

Eyebrows
Players will be able to choose eyebrows for their Mii. The players can change the color of the eyebrows, as well as the exact position where they are or how fat they are.

Eyes
Players can choose 48 different kinds of eyes-and the color of the eyes as well. Players can as well choose how big or small the eyes are and put the eyes in a certain position.

Nose
Here, players can change the size and shape of the nose. There are 12 noses to choose from and some of them are pretty strange which make the Mii more comical. The first and fifth noses are the closest ones to a real nose.

Mouth
Here, players can choose the shape of the mouth, the size and where they want to put it. Some mouths have full color lips and players can change the color of the lips to orange, red or pink.

The player can choose if the Mii will smile, give a little frown or have a big toothy grin. There are 24 mouths to choose from.

Facial Hair, Glasses and Mole
Here players can choose if their Miis will have a mustache, beard, glasses or a mole. There are three types of mustaches and three types of beards.

In the glasses section, the player can choose if the Mii will have glasses or sunglasses. Also the player can choose diferent color frames for the glasses. Also the player can choose if the Mii will get square or oval glasses. Of course the Mii doesn't need glasses.

Finish
Of the Mii turned out good, the player can click the "Quit" button and save. If the Mii doesn't look good the player can fix those things that turned out wrong.

After the player finishes the Mii will be kicked onto the Mii Plaza. All Miis created on the Wii, will be on the Mii Plaza.

Trivia

 * Miis first receive voice acting in Mario Kart Wii, not counting minor background noises that they first made in Wii Play's Shooting Range event.
 * On a Wii U, if the player goes on the Internet Browser from the HOME Menu and the curtains are closed, the spotlights shine on the curtains for about 15 seconds, then the current user's Mii comes up and starts doing different activities. They include singing, juggling, twirling a baton, dancing with a striped cane, doing a magic trick, playing with the user, and sleeping.
 * Miis are the only playable characters in the Super Smash Bros. series to be represented by the Super Smash Bros. emblem and the only fighters to not be fought in All-Star Mode.
 * In Japan, there were limited edition Miis with golden pants which could be collected by scanning special QR Codes.
