Lorne is a Mii from the Switch.
Lorne originally appeared as the default Mii for the Injured Elf role in the files of Miitopia (Switch, Demo), but unused within the demo itself. He later appeared in the full game of Miitopia (Switch). Once the player replaces him with a Mii of their choice, Lorne 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 Town02_Injured.charinfo.
His Mii name in his Mii data file is キズエルフ, which translates to "scratched elf". His Mii ID is as follows: 54 A0 E3 74 38 EB 4C F4 86 3B 66 C7 01 9F 37 DB
His Mii data file does not contain any unused Mii data.
Lorne's role in Miitopia (the Injured Elf) is described as so:
The town's appointed guard, except
he's forever lost in daydreams.
He seems to bear resemblance to Miis featured in Miitopia (3DS) promo art for multiple monsters, 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 Lorne and the promo art Miis are meant to be the same character.
The names of the default Miis in Miitopia Switch often vary drastically depending on region. Lorne's name on the Mii Library is going off of the US English version, for consistency. A chart containing all of Lorne's names is located at the bottom of this page.
Below is a screenshot of Lorne in-game as his role in Miitopia.
A very similar Mii does appear in promo art for Miitopia (3DS), on the face of several monsters. Lorne later appeared in promo art for Miitopia (Switch) for the same monsters. Note that these monsters only take the faces of a specific roles, none of which are the Injured Elf. For some images, you may have to open them in a new tab to see the whole render.
