|#10 - Junko Enoshima from Danganronoa: Trigger Happy Havoc|
And with that, you fell for Junko's trap. She was able to fake her death by having her twin sister, Mukuro Ikusaba, impersonate her in the beginning, then had her killed so that she would have a solid alibi as to why she wasn't the mastermind behind Hope's Peak Academy. In truth, Junko was responsible for the whole thing and is completely psychotic beyond all comparison.
Junko is the self proclaimed Ultimate Fashionista, but that's really a cover for her actually ultimate skill. Junko is the Ultimate Despair, a person who wants nothing more than to watch people suffer and die at her hands. To say that she's a sadist and a monster is doing a disservice to her. She loves to when people kill each other and watches as the other students kill each other one by one. Everyone claims that they're going to stop her, but their attempts are pointless. Junko would only die when she wants to die. Until then, she'll gleefully watch everyone murder each other and watch the world burn.
If that wasn't terrifying enough, Junko frequently splits between multiple personalities, each one embodying a specific trait of hers. Each personality hides from the fact that she's really a cold, emotionless monster. The foresight she has to break people's wills is truly frightening, going so far as to break Byakuya Togami's spirit, the Seto Kaiba of the game. Even when you do eventually beat her, she dies on her own terms. She commits suicide in a giant, sexual explosion, loving all of the despair and torture that she inflicts on herself. And guess what? Even after being burned alive, pummeled, electrified, shot through a rocket, and crushed in a trash compactor, she still manages to stay alive in the sequel! She digitizes herself and attempts to resurrect herself by, you guessed, putting people through ultimate despair and forcing them to submit to her will. Even though she may be one of the youngest villains on this list as well as one of the few female villains, Junko is one girl that you want to avoid at all costs.
