It could be that Allys was rejected by society because of her looks or some other reason. In her revenge, she turns into a monster - like figure and preys on the people who shunned her.

Since I'm not familiar with this particular 'allys revenge horror story', I can only guess. It might start with Allys being a victim of some sort of injustice. Then, in her quest for revenge, she might use dark magic or be part of some haunted scenario. For example, if she was bullied at school and then died mysteriously, she could come back as a vengeful spirit to haunt those who wronged her. It could involve creepy settings like an old, abandoned building where she lures her victims.
