Miss Heinous

I always thought Miss Heinous had one of the most interesting character arcs in Star vs the Forces of Evil. She initially came off as a typical villainess that became bit of a joke due to losing her position as headmistress of Saint Olga’s Reform School. Then it turned out Miss Heinous was actually a tragic figure, because she was supposed to be the queen of Mewini but got switched out with a peasant girl due to being part monster and suffered an abusive upbringing. I actually would have rooted for Heinous to take the throne if she hadn’t become a soul sucking monster and was willing to kill Star.
