Abigail is a Mii from the Switch.
Abigail originally appeared as the default Mii for Elven Retreat's Green-Eyed Lady role in the files of Miitopia (Switch, Demo), but unused within the demo itself. She later appeared in the full game of Miitopia (Switch). Once the player replaces her with a Mii of their choice, Abigail 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 Town02_Jealousy.charinfo.
Her Mii name in her Mii data file is くやしがる, which translates to "be sick". Her height is set to 55 and her build is set to 21. Her Mii ID is as follows: 7D 9B 69 05 1A 0C 4A FD A5 E3 35 3D D5 2A 98 3F
Her Mii data file does not contain any unused Mii data.
The names of the default Miis in Miitopia Switch often vary drastically depending on region. Abigail's name on the Mii Library is going off of the US English version, for consistency. A chart containing all of Abigail's names is located at the bottom of this page.
Abigail unfortunately does not appear in any promo art. Below is a screenshot of her in-game as her role in Miitopia.
