Mii

A Mii is a customizable avatar used on several Nintendo consoles and mobile apps. Miis were first introduced on the Wii in 2006, and returned on the Nintendo 3DS, Wii U, the Nintendo Switch, and various Nintendo smartphone apps. Miis are based on humans, and they can be created using different body, facial and clothing features. Miis can then be used as characters within games on the consoles, either as an avatar of a specific player, such as in Wii Sports, or in some games portrayed as characters with their own personalities. Miis can be shared and transferred between consoles, either manually or automatically with other users over the internet and local wireless communications.

Miis appear in a few Sega games for Nintendo consoles. Their first appearance in Sega-produced media is Jissen Pachi-Slot Pachinko Hisshōhō! Hokuto no Ken Wii, a collection of pachinko games for the Wii. Aside from this, Miis also appear in some Sonic the Hedgehog games and some crossover series including Mario & Sonic and Super Smash Bros..

Super Smash Bros. for Nintendo 3DS / Wii U
Miis (named Mii Fighters) are playable fighters in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U. They represent the Super Smash Bros. series in their emblem, even though Miis do not originate from the Super Smash Bros. series. They are the only playable fighters who have this emblem and the only ones who are not fought in All-Star Mode.

When creating a Mii Fighter, the player can select it to have one of three different classes: Mii Brawlers, Mii Gunners, and Mii Swordfighters. Brawlers specialize in fighting melee style, while Swordfighters and Gunners utilize a sword and a gun in their movesets, respectively. Each class can select four out of twelve special moves, making up a total of 36 special moves. When playing online, Miis can only be used when playing in With Friends mode.

When customizing a Mii, the player is able to equip it with custom outfits and headgear, with more available to be purchased as DLC. In terms of equipment, all Miis can use the Jacket and Boots equipment; Mii Brawler can use the Gloves; Mii Swordfighter can use the Sword; Mii Gunner can use the Arm Cannon.

The Multi-Man team is also composed of Miis, called the Fighting Mii Team, which replace the Fighting Alloy Team from Super Smash Bros. Brawl. Miis are loaded from those saved on the console and given a random class of Mii Fighter. These Miis are dressed full black, and cannot use shields, special moves, and items. They also cannot grab ledges, but will use a Footstool Jump on other Miis to recover.

In Super Smash Bros. for Nintendo 3DS, regular Miis also appear in the Tomodachi Life stage, also randomly loaded from the system.

At E3 2014, where the Mii Fighters were first officially revealed, Masahiro Sakurai explained that Miis were considered to be included as playable characters in Super Smash Bros. Brawl, but they were ultimately not included as Sakurai felt that it did not seem right at the time for Miis to be punching and kicking. The Miis were also removed due to online bullying and Sakurai thought that the Miis had a lack of character to themselves and would not be interesting enough characters.

Super Smash Bros. Ultimate
Mii Fighters return in Super Smash Bros. Ultimate. Their proportions have been altered so that they have smaller heads, and their default clothing have been altered as well. Additionally, players can choose between 12 different voice options to set for their Mii Fighters, each of which can be played at three pitches: low, medium, and high.
