A Mii is a customizable avatar that can represent a player or other character in many Wii, Wii U and Nintendo Switch games and online features. It is the first customizable avatar in a Nintendo system.
In the Sonic continuity, some games allow a person's Mii to participate in the game instead of the default characters. In other Sonic games, Miis can act as an icon for the player's save file, so the player doesn't get them mixed up with others.
Sonic games featuring Miis
Mario & Sonic at the Olympic Games seriesMiis can be used in any Olympic event. All Miis wear the same athletic outfit, but in different colors depending on the Mii's color. All the Miis share the same animation and poses with Mario. The announcer refers to every Mii as simply "Mii" rather than their unique names. The Miis themselves are completely silent, having absolutely no lines whatsoever. Their stats are all five out of ten.
There is a lot more to do with the player's Mii in the later games than there was in their predecessor. In Mario & Sonic at the Olympic Winter Games, using the earned star tokens, players can purchase many different styles of shoes, gloves, shirts and head gear for their Miis to wear which will change the stats. In addition, players can obtain full costumes of the characters from both Sonic and Mario series to dress their Mii in. Similarly, in Mario & Sonic at the London 2012 Olympic Games Mii clothes and outfits can be won using Scratchers or purchased for ten blank scratchers. Miis all have the same stats, and they have the same moveset as Mario by default. However, if a Miis outfit is customized with a character suit or certain gear, their stats will increase. They still have no speaking lines. Despite the character's gender, they can be in any outfit, such as a male character wearing the Rouge costume or a dress. The costumes also appear in Mario & Sonic at the Sochi 2014 Olympic Winter Games and Mario & Sonic at the Rio 2016 Olympic Games.

Sonic & Sega All-Stars Racing
Miis can race in the Wii version of Sonic & Sega All-Stars Racing. Miis drive the Super Zoomer and its All-Star Move is the Parade Power where four Miis pick up your car and start running, knocking out anybody in the way.
Miis are playable in the co-op feature of Sonic Colors. In the Game Land zone, they can use all of Sonic's/Virtual Hedgehog's powers and can use the Wisps powers. Their appearance is the same as the selected Mii, same head and arm shape but with Sonic's upper body and shoes. The voice when selected a color Wisp remains the same. Same as with Virtual Hedgehog, should one jump on the Mii's head, he/she will become dazed. A Mii can also be the icon on the player's saved file.
Sonic & All-Stars Racing Transformed
Miis return in the Wii U and 3DS versions of Sonic & All-Stars Racing Transformed. They drive the Super Zoomer which is modeled after the logo from the Sega arcade game OutRun, except with the paint job of the Mii's favorite color. Miis are unlocked in the Wii U version by completing the first GP circuit on any difficulty, which also unlocks the mirror GP circuit.
For the 3DS they are unlocked by clearing all Mirror GPs. In the Wii U version the player is restricted to their personal Mii while in the 3DS version the player can pick from any Mii on the console and from some Quest Miis. In Download Play on the 3DS the Miis are used by the players receiving the game.
In this Nintendo game that guest stars Sonic the Hedgehog as a playable character, the player can use their Mii on Wi-Fi to represent themselves. Miis also appear as audience members in some stages, like Mario Circuit and Pokémon Stadium 2.
Samba de Amigo (Wii)
In this maraca shaking musical game, Sonic and some Chao make very energetic dancing cameos in a Green Hill Zone themed stage. Also present in Green Hill Zone are the player's Miis who are more than happy to join in on the party.
Miis make a cameo in Sonic Generations (3DS) as a Profile Card. They can also be seen through StreetPass. They also appear as Wi-Fi icons.
Sonic the Hedgehog returns as a playable character in this next installment of the Super Smash Bros. series and the player can have their Mii (known as a Mii Fighter in the game) partake as a playable character as well, with the choice of three weapons that goes with their different fighting styles: a brawler; a sword fighter; or a gunner. Costumes based on Tails and Knuckles appear as downloadable outfits for Mii Gunner and Mii Brawler respectively.
The Mii Fighters return as playable characters in Super Smash Bros. Ultimate. After the 3.0 update of the game, several new features were added, one of which was returning Mii Fighters DLC costumes from Super Smash Bros. for Nintendo 3DS and Wii U. The first revealed costumes included the Tails Mii Gunner and Knuckles Mii Brawler costumes.
- A Mii's hands are round spheres, but in the Mario & Sonic at the Olympic Games series, Miis have opposable thumbs.
- Miis physical appearance has been known to vary, in Wii Sports Miis (in most cases) had no legs, but in Wii Sports Resort they have legs. In Wii Sports (in most cases) they had no arms, but in Sonic & Sega All-Stars Racing, they have arms.
- Although players can customize the weight and height of your Mii, all Miis in Sonic games will have the same height and weight regardless.
- If the player selects their Mii as a favorite in the Mii Channel, not only will they have red pants but in Mario & Sonic at the Olympic Games part of the Miis outfit would be red as well (i.e. wrist bands)
- It is possible that Miis could have super-human speed and strength, considering they compete on an even level with the other default characters in the Mario & Sonic series.
- It is possible the Parade Power is based on "Mii Parade" considering that they make a type of parade during their All-Star move.
- The Miis can be made to look like Sonic characters to some extent, as well as most non-Sonic characters, giving you chances to "play as" some out-of-game-characters (like Mario or Link), often offering comedic results. The Avatars also do this to a lesser extent.
