2. Medusa Gorgon (Soul Eater)

There is failing to understand your child, and then there is Medusa Gorgon. She locked Crona in a dark room, starved them, forced them to kill small animals, and physically fused a weapon into their bloodstream just to create the perfect killing machine. Medusa doesn’t even view Crona as a person; they are just a lab rat. Every ounce of anxiety and pain Crona suffers is a direct result of Medusa’s psychotic ambitions.
