Miis are characters made on the Wii, Wii U, Nintendo 3DS, and Nintendo Switch that look like 3D humans. There is a Wii Channel devoted to making them, called the Mii Channel. They can be created whenever the player wants, using different head, body, eye, hair, mouth, nose, and glasses types. Up to 100 Miis can be stored on a Wii, 3DS, or Switch and ten per each Wii Remote and up to a whopping 3000 Miis can be stored on a Wii U. The main purpose of Miis is to be an avatar of the creator but are used to a wider extent. Miis are compatible with Mario Kart Wii. They can be any size, depending on their height and weight. This makes them the most versatile characters. However, Miis are only middleweights in Mario Kart 7. Miis must be unlocked. The Mii's voice also varies depending on the color their shirt is. Also, Miis from your Mii plaza sometimes appear in the crowd, or on statues in some tracks. Miis have two outfits: Mii Outfit A and Mii Outfit B. In Mario Kart 8 and Mario Kart 8 Deluxe, Miis wear a different outfit with a helmet on their heads. amiibo can unlock special outfits for them as well.
The Mii's have four stats similar to Baby Peach, Mario, and Donkey Kong but depends on the weight of their class will give different stats in Mario Kart Wii but however the Large Mii is the only character in the game to only have 5 stats thus granting them somewhat of a special advantage, However, in Mario Kart 7 the Mii's are under as Medium Weight class along with Mario and Luigi.

- Mario Kart 8 Deluxe was the first game on the Nintendo Switch that supports Miis, as well as the only one for over a year, however, the games Go Vacation and Super Smash Bros. Ultimate support Miis.
- Miis are the only characters in the original Mario Kart 8 that aren't unlocked at random instead they are always the 8th to be unlocked.
- In Mario Kart Wii, when playing as a Mii, some courses will change the head of some character's statues into a random Mii in the game. (ex. Luigi Circuit)
- Mario Kart 7 is by far the only game they appear in where Miis are not the weight you set for them. Instead they are always medium regardless to how big or small they are.
