Miis are customizable characters that were debuted alongside the Wii via the Mii Channel, the Nintendo 3DS, the Wii U via the Mii Maker, the Mii Maker via Nintendo Switch, and on iOS and Android devices through the Miitomo app. Their name is obviously a reference to the name of the Wii and the fact that the character can reflect the player (and of course others as well). They've since become a phenomenon and arguably the mascot of the console excluding Mario.
Once the player has created a Mii, they're then allowed to place the character in a game of their choice and turn them into a playable character.
The Miis live in a small pocket-dimension called Mii Plaza. A new version of the Mii Plaza is present on the Nintendo 3DS in the application titled StreetPass Mii Plaza, where they are the main characters of Puzzle Swap & Flower Town, and the main protagonists of Find Mii, Mii Force, and Monster Manor.

WiiMiis first appeared on the Wii console in the Mii channel, where Mii creators could choose what the Mii looks like and than save the Mii's look. They also appear in the Wii series, which includes Wii Sports, Wii Play, Wii Fit and Wii Music. These games' main characters happen to be Miis, and they're used in nearly every mode of each game. they're also usually seen in the background as virtual spectators (example: In Wii Play's ping pong game, they're seen around the table cheering you on. The table tennis mode in Wii Sports Resort actually had the Miis playing the game). In Nintendo Land, Mii Characters are for the first time playable in full Nintendo Costumes.
Nintendo 3DSThe Nintendo 3DS included a Mii Maker built into it. It's almost identical to its Wii counterpart though includes the ability to take a picture of someone and have the application do all of the work. Plus, there are some new Mii parts. It can detect nearby Wiis and download Miis from that system. However, it can't transfer them from the Nintendo 3DS to the Wii due to the new parts the Miis now have. It is also easier to share Miis as there is a new feature to make QR codes which can be scanned. Several games for the Nintendo 3DS have made use of the Miis in the Mii Maker, including Pilotwings Resort, AR Games, Nintendogs + Cats and more.
Mii's are featured prominantly in the new console feature "Miiverse". The Mii Character of the user will represent them on the many community forums accesable from the "Communities" menu. When posting,the user can choose an emotion for their Mii to display (Neutral,Happy,Winking,Shock,Cringe,and Sadness). The Mii Maker returns,but is now in the form of shelves your still-standing Mii Characters will stand on (If you use a Wii Remote,point at a Mii,and press A,you can change their poses).
Mii's once again return for Nintendo Switch. However, there are several changes. While Mii's can still be used for the players avatar, players may also use icons of various Nintendo characters, while Mii's are an optional feature for the Switch System. Mii's Customization remain essentially the same from 3DS and Wii U. However, there are a few additions. A Hair Color can now have a wide variety of 100 color shades, rather than just tint colors like Yellow, Brown, Black, etc. Another new feature is that Mii's have a few new glasses. Their glasses can also be changed to full color (same as hair colors). The Look-Alike option of creating a Mii last seen in Wii is also back. Miis may also be scanned by amiibo, sometimes transferred from a 3DS or Wii U. Unfortunately, unlike the Wii U, which supports over 3000 Miis in one console, the amount on a Switch was reduced back to 100.
