The 13 Greatest Villain Vs. Villain Fights In Anime History

Warning: this fight is manga-only, so if you're an anime viewer who doesn't want spoilers, skip this part.

Hisoka Morow may be a villain, but he never really aligns himself with any particular side. His goal in life is to test his strength against the strongest opponents he can find. Sometimes, that means siding with the heroes to protect them until they're strong enough that he may fight them himself, or launching strikes on other villains who he thinks would be fun to spar with. 

One of his most interesting fights with another villain happens against Chrollo Lucilfer, the head of the Phantom Troupe. Their battle, which involves an exchange of nen-based moves and ends with Hisoka's demise (which he subsequently revives from), is one of the most intense fights in all of Hunter X Hunter.

Though Mayuri Kurotsuchi may fall on the same team as the heroes most of the time, he can't exactly be called good - in fact, his unethical experiments on other human beings make him pretty villainous. But despite his willingness to torture people in the name of science, he'll still rescue his comrades if need be.

He fights Szayel Aporro Granz, a scientist working for Aizen and one of his Espada, who torments Renji and Uryu using a voodoo doll. Kurotsuchi defeats Szayel with some difficulty, spending most of the battle lecturing him about his failure as a man of science.

The fight is clearly less about protecting Kurotsuchi's comrades than it is about his personal ideals. Even the way he defeats Szayel sounds incredibly cruel, with the Arrancar forced to watch his demise approach him over what, at least to him, feels like centuries.

The end of Fullmetal Alchemist: Brotherhood consists of a no-holds-barred brawl with multiple fights occurring simultaneously. One of the most interesting ones occurs between Greed and Father - his creator, and the person to which he supposedly answers. 

By the time he goes up against Father, Greed has worked alongside the heroes to take on the homunculi who remain alive. Father has absorbed God and tries desperately to remain in control, only to eventually fail. He tries to absorb Greed and use his Philosopher's Stone - which Greed allows because it's the only way to keep his host body, Ling, from being absorbed. But while he's inside Father, he takes the opportunity to transform Father's body into a more easily breakable substance.

Though created to be a villain, he joins the side of good in his last moments of existence. 

Though not a villain for the entirety of Naruto, Sasuke Uchiha acts like one when he chooses to go against Konoha and go against his former allies, becoming a villain regardless of what viewers might think of the reasons behind his behavior. 

Without Danzō Shimura, Sasuke never would have become a villain - Danzō, as it turns out, orders Itachi to slay the rest of the Uchiha clan. Sasuke now knows the truth and is ready to tear Danzō apart. Danzō fights using the power of Uchiha eyeballs embedded in his withered arm. While extremely gratifying to watch Sasuke get revenge and defeat this dirtbag, one can't easily forget that Sasuke also wants to take his anger out on innocent people.

Yami Marik and Yami Bakura both exist as malevolent forces who take control of other peoples' minds and bodies - and in two episodes of Yu-Gi-Oh!, they face each other down in a game of Duel Monsters. Both evil entities wish to gain possession of the others' millennium item, as well as to eliminate the others' soul - or send them to the Shadow Realm in the heavily edited dub.

The duel involves tons of trash-talking and bragging about their respective skills, but in the end, Yami Marik proves victorious. Yami Bakura retreats into a millennium item, promising that Yami Marik hasn't seen the last of him, while Marik moves on to controlling Tea's body to move on to the next phase of his evil plan.

Chisaki Kai, a terrifying villain, reveals exactly what he's made of when the League of Villains invites him to meet with them in an abandoned factory in the hopes of recruiting him. Chisaki finds their plans laughable and disorganized, freely insults them, and then asks them to be subordinate to him instead. 

The League of Villains gets angry, and they enter a fight that leaves Magne's body blasted in half, Mr. Compress' arm torn off, and one of Chisaki's allies getting slain. Chisaki leaves and the reader gets the sense the heroes will soon going to have something far more dangerous to deal with than just the League of Villains.
