It’s always a wild ride when the main character goes rogue and wipes out everything in their path. Watching anime where the hero turns into an antihero shows just how terrifying it can be when the good guys finally snap.

So, here’s a list of anime where the heroes embrace the dark side.

Arifureta

• MyAnimeList: ⭐️ 6.72

The story follows Hajime, a high schooler who, along with his classmates, ends up in another world. Sounds cool, right? Not exactly. He doesn’t really get along with the others.

They were summoned to save this new world and each of them got powerful abilities to help. Everyone except Hajime. His only skill? Transmutation. Basically, the fantasy equivalent of being the kid picked last for dodgeball. Naturally, his classmates make fun of him.

But things go from bad to catastrophic when one of them betrays him, sending Hajime plummeting into the abyss. From there, this story takes a dark turn – the weak underdog becomes a ruthless antihero, clawing his way back stronger than anyone else. It’s the kind of isekai where revenge tastes better than victory.

29

Angels of Death

• MyAnimeList: ⭐️ 6.96

Angels of Death is pure psychological chaos from the first episode. The plot centers on Rachel, a girl who wakes up in a strange basement with no memory and one wish – to die. Then she meets Zack, a cold-blooded killer with a bandaged face and an even darker heart.

Instead of killing her outright, Zack makes a deal: he’ll grant her wish, but only if they can escape the twisted building they’re trapped in. As they climb floor by floor, everything shifts. Rachel finds herself wanting to live again, and Zack – to protect her. Their bizarre bond turns this horror story into something much deeper, mixing death, desperation, and the fragile spark of hope.

Black Jack

• MyAnimeList: ⭐️⭐️ 7.58

Black Jack is a legend from the 90s anime era. It tells the story of Kuroo Hazama, a genius surgeon without a medical license – and with a seriously dark past. He takes on medical cases everyone else calls hopeless, and his patients pay a fortune for his help.

Because of his greed and unorthodox methods, people see him as a heartless villain. Yet, no one can deny his brilliance. Each episode blurs the line between genius and madness as Black Jack saves lives in ways that defy both science and morality. Sometimes you can’t tell if he’s a hero or a monster – and that’s what makes it unforgettable.

27

Classroom of the Elite

• MyAnimeList: ⭐️⭐️ 7.85

This anime deserved its second season way sooner than it got one. The main character, Kiyotaka Ayanokoji, isn’t your typical hero – he’s cold, calculating, and sees people as tools to be used.

The story takes place in an elite high school that ranks students into four classes, from A to D. Those in Class A live in luxury, while Class D students – where Ayanokoji ends up – get the short end of the stick. Despite being insanely intelligent, he hides his true potential, deliberately scoring low and avoiding attention.

Behind the scenes, though, he’s pulling strings, manipulating outcomes like a silent puppet master. Few know how deep his mind games go. Ayanokoji’s mysterious past explains his detached, analytical nature – but the anime only gives us hints. If you really want to know what shaped him, you’ll have to pick up the light novel, because the screen leaves those secrets buried.

2026 Update

Updated by Vasily Klyachkin: Added a new series that fans of “reincarnated-as-a-villain” stories will absolutely love. Meet:

I’m the Evil Lord of an Intergalactic Empire!

In I’m the Evil Lord of an Intergalactic Empire! (Ore wa Seikan Kokka no Akutoku Ryoushu!), we follow Liam, an ordinary guy who wakes up in the body of a noble within a massive galactic empire. Tired of being the nice guy, he decides it’s time to live for himself. He becomes a self-proclaimed tyrant, doing whatever he wants and not caring about the fallout. But here’s the twist – the more he tries to act like a villain, the more good he accidentally does.

Instead of enemies, he gains loyal followers. Instead of tearing the empire apart, he ends up strengthening it. And the people? They adore him. Liam can’t figure it out – how did trying to be selfish turn him into a hero?

As the story unfolds, he realizes that being a villain isn’t so easy when your every move somehow makes the world a better place. Ironic, isn’t it?

Every anime on this list dives deep into the darker corners of power, revenge, and human nature. The genre of antiheroes and morally gray characters doesn’t come around often, which makes these stories all the more captivating.
