Güsstav

A large woman and cruel magic user who likes to see men running in fear and dying horribly. A narcissist, she likes young, beautiful boys and brainwashes them and performs cruel and morbid surgeries by adding animals parts on them, with one of the victims being Ato's brother Klato. Like the Fake Kfer, the Fake Güsstav does not care about her troops and even kills them personally if they try to kill a pretty boy she fancies. When she first encounters Koinzell, she wants to make him one of her toys which prompts her to rape him but Koinzell uses that to his advantage to escape his constraints and in the process cuts her face. Enraged, she transforms using Wischtech magic into a hideous beast but is killed by Koinzell. (Source: Wikipedia, Übel Blatt Wikia)
