A character making a condescending, menacing, sinister, or downright psychotic facial expression. Often shown with an evil smile, smirk, or sneer, giving them a sense of utter disgust or contempt towards the viewer or other characters.
It may be seen when a nice character suddenly has an evil out of character moment, or in characters who are canonically evil (particularity when betraying the protagonist), or in the more crazed type of yandere.
