Mini/Miitopia

Minis created in Miitopia badfics are mini-Fiends or mini-Terror Fiends. The regular variant appear if the fic misspells the name(s) of monsters, terminology, or location(s), while the terror variant appears if a character's name or role is misspelled. For example, Draggon would be a mini-Fiend, but Domnnic (a named dragon and important character) would be a mini-Terror Fiend. Both variants are docile (to agents, at least), but, if the first mini is anything to judge by, they are slightly mischievous. Both variants are regular-sized (which is still small compared to the normal human), hence why one of their nicknames is definitely-not-miniature minis.

Canon Origin
Both Fiends and Terror Fiends are types of monsters found in the game. Fiends appear earlier than Terror Fiends, but are semi-common enough to be a huge nuisance for players. Each have a 90% chance to use a 999 damage attack, which is an instant KO in all except really rare situations. They both look similar, with red hair, scythes, red tattered clothes, and red irises with black sclera. The most noticable difference is that Terror Fiends have two eyes, while Fiends always have one. Terror Fiends are also stronger, with HP of 666.
