Underswap Temmie

Underswap is an AU that has Temmie in it.

Personality
Initially, Temmie operates under a façade of friendliness and politeness. She pretends to be "stupid". Temmie often greets the protagonist with "hOI!", calls themself  "your best tEM," and, like their mother, appends polite words such as "gosh" and "golly" to the ends of their sentences. Whenever Temmie drops this guise of friendliness, they often call the protagonist an "idiot." Temmie has a malevolent and cruel disposition, berating the protagonist for not following her "kill or be killed" philosophy. Despite this, she also criticizes the protagonist at the end of the Ruins if they killed any monster. Temmie is manipulative, devious, and a cunning planner and subtle if the circumstances require it. Temmie can retain her memories between SAVE's because she was once able to SAVE. She is also shown to be extremely cowardly, as she kills their former mother to appease the protagonist in a vain attempt to save her own life in the Genocide Route's conclusion. Because Temmie has no SOUL of their own, Temmie can't feel most emotions, including joy or love.

Appearance
Temmie resembles a cat with dog ears (She has four ears) on the side of her head as well as her normal cat ears on the top of her head. She has shoulder length black hair, and a purple and blue striped shirt, which suggests it can be the tem shopkeeper that got swapped with flowey, because the tem shop keeper wears a striped shirt, even though the colors of the shirt are different. She also appears to have white fur and a small tail. She is usually shown with a calm, friendly expression, grinning at the protagonist

Abilities
Temmie can make their face do different expressions of other monsters and faces.
