Maria is a Mii from the Switch.
You may get them confused with Maria (Wii), Maria (Wii U/3DS), Mariko (WaraWara Debug), or Mari (WaraWara Debug)!
Maria (Switch) originally appeared as the default Mii for the Nintendo Fan role in Miitopia (Switch, Demo). She later appeared in the full game of Miitopia (Switch). Once the player replaces her with a Mii of their choice, Maria would never appear again, unless that Mii is deleted. Her Mii data file can be found in \cmn\storedata\npc_default_mii.sarc and is named Amiibowoman.charinfo.
Her Mii name in her Mii data file is にんてん, which translates to "Ninten". Her height is set to 67. Her Mii ID is as follows: 65 03 B4 C9 8D D6 4A FE B5 A7 B6 74 40 C4 01 0F
Her Mii data file does not contain any unused Mii data.
Maria (Switch)'s role in Miitopia (the Nintendo Fan) is described as so:
A fan of a certain games company.
She's very interested in amiibo...
Maria (Switch) shares her name with another two Wii CPU Miis and Wii U/3DS CPU Miis. The Wii U/3DS Maria results in there being two different Marias in the same game.
The names of the default Miis in Miitopia Switch often vary drastically depending on region. Maria's name on the Mii Library is going off of the US English version, for consistency. A chart containing all of Maria's names is located at the bottom of this page.
Maria (Switch) unfortunately does not appear in any promo art. Here is a screenshot of her in-game as her role in Miitopia.
