Mii
Nintendo character
The male and female default Miis on the Wii
First appearance	Mii Channel 2006

A Mii (/miː/ MEE) is a customizable avatar used on several Nintendo video game consoles and mobile apps. The name Mii is a portmanteau of "Wii" and "me", referring to them typically being avatars of the players. Miis were first introduced on the Wii console in 2006 and later appeared on the DS, 3DS, the Wii U, the Switch, and various apps for smart devices such as Miitomo.

Miis can be created using different body, facial and clothing features, and can then be used as characters within games on the consoles, either as an avatar of a specific player (such as in the Wii series) or in some games (such as Tomodachi Life and Miitopia) 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.

On the 3DS and Wii U, user accounts are associated with a Mii as their avatar and used as the basis of the systems' social networking features, most prominently the now-defunct Miiverse. On the Nintendo Switch, a Mii can still be used as an account avatar, but avatars depicting various Nintendo characters are also available. Miis are also used as profile pictures for Nintendo Accounts and can be used in Nintendo smart device games such as Super Mario Run, Mario Kart Tour and the now-defunct Miitomo. Games such as Wii Sports, Wii Sports Resort, Wii Sports Club, Nintendo Switch Sports, Mario Kart Wii, Mario Kart 8, Go Vacation, Super Mario Maker 2, Super Smash Bros. Ultimate and New Super Mario Bros. U Deluxe use Miis as playable characters.

Nintendo's idea of a free-form personal avatar software was discussed at the Game Developers Conference in 2007, a year after the Wii was released. There, Shigeru Miyamoto said that the personal avatar concept had originally been intended as a demo for the Family Computer Disk System, where a user could draw a face onto an avatar. Miyamoto commented that the concept could not be turned into a game and was discarded.

In late 1999, during the Nintendo 64 era, the 64DD (a disk drive peripheral for the N64) was launched in Japan. Released in 2000, Mario Artist: Talent Studio featured an avatar maker, which includes clothes and a built-in movie editor. The player can optionally utilize the Game Boy Camera and the 64DD's Capture Cassette to put their own face upon the avatar. Nintendo had produced a short film using the game's avatar maker to demonstrate its capabilities. Talent Studio was one of Nintendo's first public debut of avatar creation.

The next avatar implementation was for the Nintendo e-Reader and GameCube. Along with the Game Boy Camera, it also includes an avatar maker. Miyamoto showed another short film they made with this software at E3 2002, under the name Stage Debut. This software, renamed to Manebito, was discontinued prior to release.^[1]

During a Financial Results Briefing Q&A with investors in 2008, Iwata mentioned that the licensed use of the Mii trademark is as valuable to Miyamoto as that of the Mario brand, implying that the company would only narrowly consider any offers from game developers to implement Miis in their games.^[2]

Nintendo designer Yamashita Takayuki attributes his work on Talent Studio as having been foundational to his eventual work on the Mii, which was necessitated by the development of the game Wii Sports.^[1]: 2

Mii characters are created and stored in the Mii Channel or the Mii Maker, which are pre-installed on the Wii and the Nintendo 3DS/Wii U/Nintendo Switch consoles respectively. While the user can assign a gender, name, birthday, favorite color, and mingle preference to a Mii, the majority of the interface used for Mii creation focuses on the appearance of its face and head: the user is given a variety of different hairstyles, eye, nose, and mouth shapes, and other features such as facial hair or wrinkles, to select from. Most of the facial features can be further adjusted, including their size, position, color, and alignment. Accessories such as hats and glasses are also available to add, and the Mii's height and build can also be adjusted. The Mii Maker installed on the Nintendo 3DS and Wii U can use facial recognition to generate a Mii, which selects facial features based on a photograph of a person's face taken with the system's and GamePad's cameras respectively. The features can then be fine-tuned by the user.^[3] These versions also have more options than their Wii counterpart. Because the selection of facial features is considered by some to be limited,^{[citation needed]} users are encouraged to develop caricatures of real people instead of accurate depictions.

Nintendo periodically released special Miis, usually during E3 or to commemorate game and franchise anniversaries. For a limited time between March 13 and 30, 2007, Wii owners in Japan were sent Mii versions of comedian Sanma Akashiya and tennis player Shuzo Matsuoka. The duo had been featured in Japanese promotions for the Wii, highlighting Miis themselves.^[4] Miis of Satoru Iwata and Reggie Fils-Aimé (the presidents of Nintendo and Nintendo of America, respectively) were released on the 3DS for the 1st anniversary of the handheld console. During 2013, Nintendo released special Miis of Shigeru Miyamoto and Kensuke Tanabe, and during E3 2013, also released special Miis for Takashi Tezuka, Koichi Hayashida, Eiji Aonuma, and Hideki Konno. Their Miis feature gold pants, as opposed to a gray pair, and cannot be edited or copied. If owners transfer them to another Wii or Wii Remote, they will be removed from their original location, instead of traditionally making another copy.

In late 2011, Nintendo released Swapnote/Nintendo Letter Box for the Nintendo 3DS, which features an original female Mii character called Nikki (ニッキー). Nikki gained a relatively small fan base of her own right, especially in Japan. After Nikki's debut, Nintendo featured the character in a few other games and apps, such as Nikki no tabi suru kuizu (ニッキーの旅するクイズ, Nikki's Travel Quiz), a Nintendo 3DS travel guide app that was exclusively distributed via the now-defunct Club Nintendo in Japan.

The Mii Channel is the app that allows Mii creation on the Wii menu. It can store up to 100+ Miis, and Wii Remotes are also able to store and transfer up to ten Miis to other consoles. It is also possible to see other Miis from TV shows and games.

Miis are intended to be an extension of the player, and in keeping with this spirit, the user can use them in several Nintendo titles for the Wii. Wii Sports is perhaps the best-known example of this,^{[citation needed]} and it adds a further personal touch to Miis by saving game statistics and records for individual Miis. Miis will make cameo appearances as computer-controlled opponents, teammates, or within the audience. Miis have been used to serve as game file icons (profiles) within several games. Often appearing as just a head for identification, this Mii has no impact on the actual gameplay other than to identify a player in another way besides the name, or representation based on looks.

Miis are primarily used in games such as Wii Sports, Wii Play, Wii Fit, Wii Party, Wii Fit Plus, Wii Music and Wii Sports Resort. Players can also use their Miis, however, in other first-party games, most noticeably within WarioWare: Smooth Moves, Mario & Sonic at the Olympic Games, Mario Party 8, Mario Kart Wii, Mario Super Sluggers, Animal Crossing: City Folk (using their Mii's head as a mask) and in Go Vacation. The Japan-only Sega game Pachinko: Sammy's Collection is the first third-party game to incorporate Miis, while the Wii version of FIFA Soccer 08 is the first third-party game released in North America, Europe and Australia to use the Mii Channel. Many other games, like We Ski, and Guitar Hero World Tour and Sonic Colors also use Miis.

While a Mii's head always remains the same, its body varies between games. For example, in Wii Sports, the Mii's body is stylized, with spherical floating hands and bearing no arms, and Mii audiences or CPUs floating with spherical bottoms with no legs instead, but in Wii Fit its body is designed to look more natural, and its weight will be determined by the weight Wii Fit found of the player in Wii Fit tests. Sometimes Miis will wear outfits in context with the game. In Super Mario Galaxy and its sequel, the Miis can be optionally used for the planet's icon that represents the save file, the other option being to use Mario characters for the planets. Only the Mii's head is shown and it's shown in a sphere shaped like the planet. In Mario Kart Wii, Mii racers can be dressed in jumpsuits, or Mario style overalls for males and a Peach style dress for females, in Dr. Mario Online Rx, Miis appear in medical clothing, and in Metroid Prime 3: Corruption, where they appear as bobblehead dolls, they will be dressed up in bounty hunter Samus Aran's Power Suit. In MLB Power Pros, Miis are designed to look like regular Power Pro-Kun avatar, with legs detached from the main body. In Dance Dance Revolution Hottest Party 2, the Mii's body is formed more like a regular human. This design was, however, criticized by IGN's Lucas M. Thomas, who sarcastically commented that "[it] doesn't look disturbing at all."^[5]

While Miis are not playable in Super Smash Bros. Brawl, the creator of the series, Masahiro Sakurai, explained that Miis were originally considered to be playable in the game, but the idea was decided against due to fears of bullying.^[6] They would eventually debut in Super Smash Bros. for Nintendo 3DS and Wii U.

Miis were incorporated in the downloadable Everybody Votes Channel, where Miis represented the voter. Up to six different Miis could be registered within the channel to use in voting. The channel was discontinued along with the Check Mii Out channel by Nintendo on June 28, 2013, as they moved on to other next-generation projects.

Another Mii-centric channel, the Check Mii Out Channel, also known as the Mii Contest Channel (Miiコンテストチャンネル, Mī Kontesuto Channeru) in Japan, Europe, and Oceania, was released on November 11, 2007. Perhaps an evolution of an idea shared by Shigeru Miyamoto at the Game Developers Conference in 2007, this channel allowed players to upload their Mii characters and share them with other users. There were also popularity contests, in which players would design a Mii that would personify a specific idea or character and then vote on the Mii that would best fit the suggestion.^[7] The channel was available for free download on the Wii Shop Channel from November 12, 2007, until June 27, 2013, when Nintendo discontinued the channel along with the Everybody Votes channel.

Although the platform lacks native support for Mii creation, a few games on the Nintendo DS console do support Mii functionality, and will work in conjunction with the Wii's Mii Channel.

Miis can be transferred from a user's Wii to supported Nintendo DS games via the Mii Channel. A code must be entered by the user to unlock the feature on the Mii Channel.

The Nintendo DS game Personal Trainer: Walking uses Miis to allow players to track their progress in the game. Players are also able to create Miis in-game.^[8] The Nintendo DS version of Final Fantasy Crystal Chronicles: Echoes of Time also uses Miis.^[9]

The life-simulation game Tomodachi Collection, only released in Japan for the Nintendo DS, also uses Miis and has a built-in Mii editor. Miis from the user's Wii's Mii Channel can be transferred to the game, and vice versa.

The Mii Maker (Miiスタジオ, Mī Sutajio, lit. "Mii Studio") is the app that allows Mii creation on the Nintendo 3DS. It can store up to 100 Mii characters, much like the Wii, and includes more facial features than the latter console. The Mii Maker installed on the Nintendo 3DS can use facial recognition to generate a Mii, which selects facial features based on a photograph of a person's face taken with the system's cameras.

Unlike the Nintendo DS, which features limited support of Mii characters, its successor the Nintendo 3DS features Miis as a standard. Similar to the Wii's Mii Channel, the Nintendo 3DS features its own Mii-creating application called Mii Maker, which is more advanced than the Mii Channel.^[10]

Mii characters can be created manually with Mii Maker as on the Wii's Mii Channel, but they can also be created automatically through the use of the Nintendo 3DS's cameras. The system captures an image of a subject's face, and the application converts the image into a Mii likeness using integrated recognition software. Automated Mii character designs can be manually adjusted. Mii characters can also be imported from the Wii to the 3DS or from the 3DS to the Wii U, however, Miis cannot be sent from the 3DS to the Wii, as Mii Maker features an expanded selection of design parts that are not available on Mii Channel.^[11]

The Nintendo 3DS can generate and read QR codes that represent Mii characters. QR codes and pictures of Mii characters can also be transferred to an SD card in any picture format, and be used in various ways, such as posting them on a web page. Miis on the Nintendo 3DS can also be used in conjunction with the device's built-in augmented reality software – the software includes a mini-app named 'Mii Pics' which allows the user to take a photo of their Mii within a regular photo, using an augmented reality card included with the system.

The first Nintendo 3DS game to include support for Mii characters is Pilotwings Resort. Miis obtained through StreetPass appear as non-player characters in Nintendogs + Cats. Mii characters also appear in Pokémon Rumble Blast, Mario Kart 7, and in many more games.

Currently, the most notable game to feature Miis in their entirety is Tomodachi Life, the sequel to the Japan-only Tomodachi Collection for the Nintendo DS. This is also the first game to give Miis complete lines of dialogue as well as the first game to allow players to choose what Miis say. Miitopia is another Mii-centric game title for the Nintendo 3DS.

A feature on the Nintendo 3DS, the StreetPass Mii Plaza (すれちがいMii広場, Surechigai Mī Hiroba) makes use of the handheld's StreetPass feature, which data can be transferred between nearby Nintendo 3DS consoles in standby mode. As Miis are gathered in the plaza, they can be used in numerous minigames, with the initial two being Puzzle Swap and Find Mii (known as StreetPass Quest in PAL regions). In Puzzle Swap, players can exchange pieces of several jigsaw puzzle panels based on Nintendo games, in which there were initially seven, but this number increased with occasional updates. Find Mii is an RPG minigame in which players use the Miis they gathered to fight through dungeons, earning accessories for their Mii. Each Mii possesses a different type of magic depending on their color, and become more powerful if the player meets them more than once. These games can be optionally played with Play Coins, though the results are more random than with Streetpass Miis. On December 6, 2011, the feature was updated to include SpotPass functionality, as well as new puzzle panels, a sequel to Find Mii, a map showing where players met other Miis, Accomplishments and a music player.^[12]

Special Miis released by Nintendo and obtained through SpotPass can also be used in StreetPass Mii Plaza. They have access to all Puzzle Swap pieces and provide a level 5 player for Find Mii.

The Mii Maker (Miiスタジオ, Mī Sutajio, lit. "Mii Studio") is the app that allows Mii creation on the Wii U. It can store up to 3,000 Miis and includes the same facial features used on the Nintendo 3DS. The Mii Maker installed on the Wii U can use facial recognition to generate a Mii, which selects the features based on a photo of a face taken with the Wii U GamePad camera.^[13]

Mii characters evolve further for the Wii's successor, Wii U. In addition to previous uses on the Wii, Mii characters are wholly integrated into the Wii U's social online network Miiverse, the WaraWara Plaza community where clusters of Mii characters crowd around the hottest games, and being depicted as personal avatars for individual Wii U players,^[14] who have the ability for twelve separate Nintendo Network ID User accounts that can be used on a single console at a time. User accounts with Mii representatives are used for both games and apps such as Nintendo TVii. Mii characters can be transferred from the Wii and/or the Nintendo 3DS to the Wii U, in which in the latter's case transfers between consoles can occur as many times as possible.^[15]

Mii characters also return as in-game characters for certain Wii U games, which in addition to Nintendo-published launch titles such as Wii Sports Club, Super Smash Bros. for Wii U, Mario Kart 8, New Super Mario Bros. U and Nintendo Land, they are also included in third-party titles such as Sonic & All-Stars Racing Transformed. In the case of Mario Kart 8, about 19+ amiibo suits can be acquired by tapping a compatible amiibo figure via an NFC reader located on the left-hand side of the Gamepad.^[16]

The Legend of Zelda: Breath of the Wild uses an evolved form of Mii, UMii, to render non-essential NPCs.^[17][18][19]

Unlike previous Nintendo consoles and handhelds, The Nintendo Switch's Mii creation software is located within the console's system settings menu instead of it being a separate app. It includes the same facial features used on the Nintendo 3DS and Wii U, while also providing unnatural hair and eye colors. The Switch's Mii creator can hold up to 100+ Miis, much like the Wii and 3DS.

Miis can be used on the Switch to represent accounts; users may optionally use a Nintendo character such as Mario as their avatar instead. Miis can be transferred between Switch consoles and imported from a 3DS or Wii U using an amiibo figure. Miis can also be imported from a Nintendo Account.^[20]

Miis can still be integrated into games as a playable character such as Mario Kart 8 Deluxe, Go Vacation, Nintendo Switch Sports, Super Smash Bros. Ultimate and New Super Mario Bros. U Deluxe. In the case of Mario Kart 8 Deluxe, about 20+ amiibo suits can be acquired by tapping a compatible amiibo figure via the NFC reader on the right-hand Joy-Con or on the Nintendo Switch Pro Controller, similar to that of Mario Kart 8 for the Wii U.^{[citation needed]} Nintendo Switch Sports introduced new avatars known as "Sportsmates", however Miis can still be selected as an option.^[21]

Currently, the most notable game on the Switch to feature Miis in their entirety is Miitopia,^[22] a remaster of the 2017 role-playing video game of the same name for the 3DS.

When the freemium mobile app Miitomo launched on iOS and Android devices in 2016, it was possible for the first time to officially create Mii characters without the need for a Nintendo console. Mii characters created on the app initially resembled their Wii U counterparts, and use the same attributes. Later updates introduced the Nintendo Switch's standards for Mii characters, also using the same attributes. Nintendo Account holders can opt to use the app to create Mii avatars without the need to link their accounts to any Nintendo console, with the option also available. Miitomo was also used to support Mii avatars on other Nintendo apps for smart devices. For example, an update released for Super Mario Run on April 25, 2017, introduced player Mii icon customization options with the support of Miitomo, and its in-game costumes, via the same Nintendo Account.^[23] Miitomo was only available in 60 of the 165 countries/territories recognized by Nintendo Accounts when it was discontinued on May 9, 2018.

On May 24, 2018, Nintendo introduced a browser-based Mii editor called Mii Studio.^[24] The editor is integrated into all Nintendo Accounts for users in all regions, including regions that originally did not have official support for Miitomo. 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 (also known as NNID).

The CPU Miis used since Wii Sports Club and Wii Party U have also appeared in Mario Kart: Bowser's Challenge at the Super Nintendo World amusement areas in Universal Studios Japan and Universal Studios Hollywood, where they appear on several screens in the pre-show rooms to showcase ride mechanics and safety precautions.^[25]

An icon of a male default Mii is briefly shown in The Super Mario Bros. Movie, where it appears on Luigi's smartphone when he receives an incoming call.
