Anime villains are not just bad guys twirling their mustaches (well, most of them aren’t). They’re often presented as reflections of the protagonists, warped by their ambitions, or their sheer disdain for humanity. Whether they’re nihilists who want to destroy the world or manipulators who twist others into doing their dirty work, anime villains force us to ask uncomfortable questions about morality and the human condition.
Sometimes, they have tragic backstories, but those don’t excuse their actions. You can understand their pain, but you still hate them for their choices. And then there are those villains who are pure chaos, who embody evil for evil’s sake, and frankly, that’s what makes anime so much fun. These characters are a reminder that not everyone can be reasoned with.
Here are the 10 most evil anime villains ever, ranked by their depravity.
10) Bondrewd (Made in Abyss)

Bondrewd is a White Whistle, one of the highest-ranking cave raiders, which means he’s already someone with extraordinary skill. But his obsession with the Abyss and its secrets pushes him far beyond the bounds of what anyone would call humane. He treats human beings as consumables to unlock relics and push “progress” past any moral line. Bondrewd is also terrifying because he rewards devotion. His followers love him, and he loves them back in a chillingly transactional way: purpose in exchange for self-erasure. That cult energy legitimizes his work and makes resistance feel small.
9) Muzan Kibutsuji (Demon Slayer)

Muzan started as a sickly noble during the Heian era. Desperate to cure his terminal illness, he underwent an experimental treatment with the Blue Spider Lily; it worked, and it didn’t. Although he gained superhuman strength and regeneration, Muzan became a demon, unable to live in sunlight. From there, he began spreading his blood to create a demon army and search for a subject who could conquer the sun. He views everyone around him as either tools for his goals or obstacles to be eliminated. To Muzan, human life is meaningless unless it serves his purpose. In that respect, he’s a pretty evil dude.

Father was a being created by alchemy in the ancient kingdom of Xerxes. His first major atrocity was the genocide of an entire civilization. He used the lives of every single citizen to create a Philosopher’s Stone that granted him immortality. Father’s ultimate scheme involved turning the whole nation of Amestris into a massive transmutation circle. By sacrificing all of its citizens, he intended to absorb the power of God. Why? Because he cannot tolerate dependence. He wants a reality where he never needs, never answers, never bows.
7) God Brando (JoJo’s Bizarre Adventure)

Dio is, without question, one of anime’s most iconic villains, and it’s not just because he’s powerful or cruel. It’s because he’s fun. From the moment he steps into the Joestar household, he cements himself as irredeemable by shoving Jonathan’s beloved dog, Danny, into an incinerator. Dio poisons Jonathan’s father, humiliates Jonathan at every turn, and even forces a kiss on Erina, Jonathan’s love interest, just to spite him. He’s evil as performance art, and the performance is convincing enough that viewers get why people follow him, which is exactly why he’s dangerous.
6) Light Yagami (Death Note)

Light Yagami is celebrated by some fans as a necessary purge, the genius who finally punishes the untouchable. But that fame becomes his camouflage and his poison. The belief that he’s fixing the world is what lets him slide from justice to vanity without noticing the cliff. He explicitly states that he will become the “god of the new world,” and from that point on, it’s clear his motivations are entirely self-serving. Light could have been a reformer, but instead, he chose the shortcut to divinity and ended up exposed.
5) Johan Liebert (Monster)

Johan is the antagonist of Naoki Urasawa’s psychological thriller manga and anime Monster. Born in the 1970s in East Germany, Johan and his twin sister were part of a government experiment called 511 Kinderheim. As a child with exceptional intelligence, Johan absorbed and internalized the horrors around him. One of Johan’s earliest atrocities was the massacre at Kinderheim 511. That is what makes Johan more frightening than ideologues like Father or showmen like Dio. He wants subtraction. Power can be bargained with. Subtraction can’t. Johan is a void that keeps erasing. Interestingly, he also wanted to erase himself through what he called a perfect suicide.
4) Griffith (Berserk)

Griffith commits arguably the most horrific betrayal in anime history. He sacrificed the entire Band of the Hawk — his friends, his lovers, his believers — branding them as meat for demon gods so he can be reborn as Femto. During this event, known as the Eclipse, he forces Guts to watch as he violates Casca, Guts’ lover. His transformation into Femto represents the complete realization of his ambition, where he fully embraces his role as an agent of darkness.
3) Friene (Dragon Ball Z)

Frieza stands as Dragon Ball Z‘s most iconic villain, a character so perfectly crafted to be despised that over 30 years later, fans still celebrate whenever he gets punched in the face. He’s a narcissistic megalomaniac who destroys planets and entire species simply because he can. What makes him even more insufferable is the fact that he’s frightfully powerful. For much of the Dragon Ball Z series, he’s the ultimate measuring stick for strength and fear. Even when newer villains like Cell and Majin Buu came along, they never quite captured the pure malevolence that makes Frieza special.
2) Isabella (The Promised Neverland)

A mother who nurtures children only to send them to their deaths? It’s hard to imagine a more twisted betrayal. Isabella is the caretaker, or “Mama,” of Grace Field House, an orphanage where children live seemingly carefree lives. However, this is all a façade. The orphanage is actually a human farm, and Isabella’s role is to raise the children to be shipped off as food for demons. Isabella is a villain who makes you question what it means to be evil. She’s a monster, yes, but she’s a monster created by a system that forces people to choose between their lives and their humanity.

Shou Tucker is a career fraud who outsourced genius to his family and called it research. Taking his daughter and combining her with her beloved dog to create a grotesque chimera (which could barely even utter words) is one of the most sickening and irredeemable acts in anime history. And the worst part? He felt no remorse. Watching him smugly justify his atrocity to Edward and Alphonse was infuriating, and every viewer collectively cheered when karma finally came for him.
