Guest C
Guest C comes as one of the six default Guest Miis that are included in the Nintendo Face Library. Because of this, he technically appears in every single game with Mii support... that's way too many to count! In nearly every single game, he's called Guest C, except for six: Big Brain Academy: Wii Degree, in which he's called "Student C", Mario Kart 8 and Mario Kart 8 Deluxe, in which he's called "Player", Tetris Party and Tetris Party Deluxe, in which he's called "Tetris3", and TV Show King 2, in which he's called "Hubble". Since he's included in the Face Library and not as a file, he doesn't have a filename and consequentially an internal ID.
He has Mingling turned off. His Mii name in his Mii data file is no name, which is the default blank name for Miis.
In his Wii-format Mii data file (extracted from memory), his Mii ID is 80-00-00-02 and his console ID is ec-ff-82-d2 (the same as all default Guest Miis). In his Wii-format Mii data file (July 2021 leak), his Mii ID is a1-8c-89-b4 and his console ID is cf-07-81-32 (different from all other default Guest Miis). In his Wii U/3DS-format Mii data file, his Mii ID is 80-00-00-02, and his MAC is EC-FF-82-D2-00-00, very similar to his console ID in his Wii-format Mii data file (extracted from memory).
In his Wii U/3DS-format Mii data file, he was originally created on a 3DS (3).
His Mii data file does not contain any unused data.
Information
As mentioned before, Guest C technically appears in every single game that contains the Nintendo Face Library (AKA, any game that supports Miis), whether you see them or not. Sometimes, they can be tricky to spot, only appearing when the player doesn't have enough or any Miis on their system at all, like in the title sequence for Pilotwings Resort.
Also mentioned earlier was the fact that all but six games call him Guest C. The six exceptions are Big Brain Academy: Wii Degree, in which it calls him Student C, Mario Kart 8 and Mario Kart 8 Deluxe, in which he's called Player, Tetris Party and Tetris Party Deluxe, in which he's called "Tetris3", and TV Show King 2, in which it calls him Hubble. TV Show King 2 is the only game to have given the Guest Miis proper names. The other Guest Mii names are Buggy, Bee, Nugget, Mango, and Shigi respectively.
Guest C has unique properties in the Japan-only DS game Tomodachi Collection (not to be confused with Tomodachi Life). When creating a new Mii to add as an islander, the Mii the game starts with is Guest C, and gets changed to either the default starter male or female Mii once you choose a gender for the Mii you're about to create. Of course, this is impossible to see in-game, as the Mii does not appear on-screen until you select a gender, but looking into the game's code and RAM confirms it is indeed Guest C.
As shown at the bottom of this page, Guest C is simply the default starter male Mii with a different skin tone.
According to the July 2021 leak, Guest C's race is asian.
Image appearances
Note: Many images on this page have been cropped. While this was done for formatting reasons (to reduce the vertical space being taken up by unimportant parts of the image), you can still open the image in a new tab to view the full uncropped image.
According to Nintendo's Mii Usage Guidelines appendix A.1, the default Guest Miis are not allowed to appear in advertising.
Do not use the default Mii inside a game. This prohibition includes screenshots of the game, and any depictions of the game that may be used on packaging, in the game manual, or in advertising.
Additionally, the back of the Wii Party box art does include Guests A (red), E (blue), C (yellow), and F (green), and although very difficult to see, B.
Similar to the above example with Wii Party, the back of the Go Play: Lumberjacks box art (shown here with the German version) shows Guest C holding up an axe.
A promotional screenshot for New Super Mario Bros. U gives Guest B, Guest C, and Guest D the names Michael, Thomas, and Catherine respectively. (Note that Michael is already the name of a Mii from Wii Sports.)
