Stan originally appeared as the default Mii for the Dark Lord 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, Stan 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 Satan.charinfo.
His Mii name in his Mii data file is だいまおう, which translates to "Great Satan". His Mii ID is as follows: 34 8F 7A 03 64 AC 4C DF 9D 8D 87 77 5F 2A D1 7B
His Mii data file does not contain any unused Mii data.
Stan's role in Miitopia (the Dark Lord) is described as so:
A wicked presence who rules
monsters from the shadows!
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 Stan 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. Stan's name on the Mii Library is going off of the US English version, for consistency. A chart containing all of Stan's names is located at the bottom of this page.
Stan appears in promo art for Miitopia (Switch) as his in-game role, the Dark Lord.
Below is a screenshot of him in-game as his role in Miitopia.
A very similar Mii also appears in promo art for the JPN version of Miitopia (3DS), where he's given the Dark Lord role as well.
