Cary is a Mii from the Switch.
Cary originally appeared as the default Mii for the Prodigious Postman role in Miitopia (Switch, Demo). He later appeared in the full game of Miitopia (Switch). Once the player replaces him with a Mii of their choice, Cary would never appear again, unless that Mii is deleted. His Mii data file can be found in \cmn\storedata\npc_default_mii.sarc and is named Postman.charinfo.
His Mii name in his Mii data file is ポストマン, which translates to "postman". His build is set to 117. His Mii ID is as follows: AA E8 45 A4 65 90 4D 31 8A A5 EB 14 80 4B 7F 06
His Mii data file does not contain any unused Mii data.
Cary's role in Miitopia (the Prodigious Postman) is described as so:
He seems to bear resemblance to a Mii featured in Miitopia (3DS) promo art, as it seems a handful of the Miitopia Switch default Miis were based around Miis that appeared in promo art for the original game, but it's unconfirmed if Cary and the promo art Mii are meant to be the same character.
The names of the default Miis in Miitopia Switch often vary drastically depending on region. Cary's name on the Mii Library is going off of the US English version, for consistency. A chart containing all of Cary's names is located at the bottom of this page.
Cary appears in promo art for Miitopia (Switch), on the face of the Burning "Party Member" Golem monster. Note that this monster only takes the face of one of the heroes, while Cary is the Prodigious Postman.
In the demo version of Miitopia (Switch), Cary never actually appears in the story, and only appears once in the casting screen. Below is a screenshot of him in-game as his role in Miitopia.
