Aconitum by Mistake Experience reviews
AU. Up until now, Aster Potter was used to have wannabes thugs after her. Usually though, it was because her mother was The Poison Ivy, not because she had (not)killed a dark lord ten years ago. Some people can really hold a grudge, but if there is one thing the aspiring villainess can do, it's ruining a perfect plan. Fem!Harry; Harley Quinn/Poison Ivy.

non timebo mala by BeaBae reviews
Bruce Wayne's ward was in third year when Lord Voldemort returned. He's not going to lose his family. Not this time. Better safe and angry with him than dead and not even able to hate him for it. Gen, Batfam. No longer a threeshot.

Boarding School AU Graduation Speech by ThePhantomOfTeamStarkid
Not a true fanfiction, but rather a graduation speech from a school that houses villains from literature. Rated T because there is violence mentioned and I would hate to be reported for not properly warning people.
