The super-powered world of My Hero Academia is filled to the brim with Pro Heroes who are always willing to help others. But sadly, this means that there are also a lot of villains who not only want to harm others, but also to prevent these heroes from helping the innocent. And this conflict between heroes and villains is the core of the series.
Because of this dichotomy, many powerful super villains have made it their objective to defeat, destroy, and even kill any Pro Hero who gets in the way of their evil deeds. There are numerous antagonists who manage to do so, to the point that they have ended the lives of popular characters.

These MHA characters managed to surpass the Number 1 Hero, All Might.
9 Dabi
Killed Snatch & Many Others
- First Manga Appearance: Chapter 57
- First Anime Appearance: Episode 31
The pyrokinetic villain known as Dabi (real name: Toya Todoroki) is one of the most volatile people in this world. It has been shown plenty of times that he's a merciless killer who won’t hesitate to burn alive anybody who gets in his path of revenge and destruction.
When the League of Villains was chasing after Overhaul’s ambulance, he used his quirk to burn Snatch alive. Snatch died after he was compressed into a ball by Mr. Compress, but it was Dabi’s flames that put an end to the hero’s life. On top of that, Dabi has also murdered over thirty innocent people, so his overall body count is quite high.
8 Twice
Killed Eel Boy, And His Dangerous Quirk Is Still Around
- First Manga Appearance: Chapter 77
- First Anime Appearance: Episode 43
The story of Twice is quite tragic: he was a nice person who became a villain because he got dealt a bad hand in life. However, he still cared a lot about his friends, so when the Pro Hero known as Eel Boy trapped Himiko Toga and Mr. Compress, a wounded Twice sent one of his clones to stab him in the back, killing him instantly.
A few moments later, Twice himself would perish at the hands of Hawks. But this wasn’t enough to stop his destructive rampage, since Toga could replicate his Double quirk with her own, Transform. So the deadly army of clones known as Sad Man’s Parade (And it’s evolved form, Sad Man’s Legion) is still around, and they have proven to be an important asset during the Final War Arc.
7 Overhaul
Killed Sir Nighteye And A Lot Of Villains
- First Manga Appearance: Chapter 115
- First Anime Appearance: Episode 62
Kai Chisaki, better known as Overhaul, is an egotistical antagonist who sees everyone as tools he can dispose of. He never hesitated to use his powerful quirk to annihilate other villains, or even his own underlings. Nevertheless, Overhaul will always be remembered as the first villain in the series who killed a prominent hero on-screen.

These My Hero Academia characters have been portrayed as having lasting endurance in battle and related physical activities.
Near the end of the Shie Hassaikai Arc, Overhaul used his quirk to perforate Sir Nighteye’s stomach, a deadly wound that would end the hero’s life a few hours later. Even though Chisaki was eventually defeated and apprehended, the impact of death Sir Nighteye's death on both Mirio and Deku would never be forgotten.
6 Muscular
Killed Water Hose And Many Prison Guards
- First Manga Appearance: Chapter 72
- First Anime Appearance: Episode 40
As soon as he was introduced, it was clear that Muscular is a heinous villain who takes pleasure in killing other people. And this is made even easier by his Muscle Augmentation quirk. He was responsible for killing the duo of Pro Heroes known as Water Hose, who happened to be Kota’s parents. And he would later try to kill Kota himself.
Muscular also murdered a bunch of innocent guards when he was escaping from Tartarus prison. After that, he was eager to kill anyone he could find on the street, and almost ended Yo Shindo’s life. Luckily, Izuku Midoriya arrived and defeated him, finally imprisoning this dangerous monster once again.
5 Stain
Killed 17 Pro Heroes And Incapacitated Other 24
- First Manga Appearance: Chapter 41
- First Anime Appearance: Episode 24
With a moniker like “Hero Killer,” it's inevitable that Stain would have one of the highest hero body counts in the series. Not much is known about the identities of the people he killed. But he targeted and severely damaged noble heroes like Ingenium just because they didn’t uphold his unrealistic values, and that says a lot.
Stain was blinded by his views on All Might and believed that everyone but him was a fake hero, which led him to a murderous rampage. To make things even worse, he inspired many other villains who, like him, believed that they live in an unfair society. Stain was both a physical and philosophical threat to the heroes.
4 The Nomu
Killed Master Driller, Native, Briareos, & Many Innocents
- First Manga Appearance: Chapter 11
- First Anime Appearance: Episode 8
It’s easy to forget that these artificial humans created by All For One and Doctor Kyudai Garaki are some of the deadliest beings in My Hero Academia. And if the regular ones weren’t already a threat, the High-End Nomu are even worse. They can damage or kill even the most experienced Pro Heroes.
Armies of Nomu have been dispatched several times throughout the series, resulting in many deaths. But they proved to be a crucial asset for the villains during the Paranormal Liberation War, where some of them could be seen killing heroes like Master Driller and Native. Finally, All For One also used some Nomu when he and other villains escaped Tartarus Prison, where they killed many prison guards, including Briareos.
3 Gigantomachia
Killed Majestic, Midnight (Indirectly), And Others
- First Manga Appearance: Chapter 162
- First Anime Appearance: Episode 78
With his enormous size, his immense durability, and his collection of quirks, there’s no doubt that Gigantomachia is one of the most menacing villains for the heroes of this series. This was proven when he was let loose during the Paranormal Liberation War. He rampaged through the battlefield, killing several people in the process.
10 Most Mismatched Fights In My Hero Academia
These fights in My Hero Academia were mismatched due to the ability match-ups and scope of their contender's powers.,
Gigantomachia crushed and killed the hero Majestic, who used to be Momo and Setsuna’s mentor. This hulking beast also trampled on many other unseen heroes and civilians, and was responsible for the death of Midnight. Even though she was technically murdered by a group of minor villains, she was severely weakened and couldn't fight back because of her encounter with Gigantomachia.
2 Tomura Shigaraki
Killed Crust, X-Less, Star And Stripe, & More
- First Manga Appearance: Chapter 11
- First Anime Appearance: Episode 8
Even though Tomura Shigaraki was quite weak at the beginning of the series, he became a menace for the heroes after he awakened his quirk and accepted the surgery to enhance his body. As one of the main antagonists of My Hero Academia, he has been responsible for a number of prominent hero deaths.
When Shigaraki awakened in Jaku City, the instant spread of his Decay quirk killed powerful heroes like Crust and X-Less. Many other innocents were disintegrated by this ability. On top of that, he later pursued and fought the American hero Star and Stripe, only to kill her because he knew how much of a threat she was to him. This final killing was a big accomplishment, because it prevented all international heroes from helping Japan during the Final War.
1 All For One
Killed All The Previous One For All Users
- First Manga Appearance: Chapter 59
- First Anime Appearance: Episode 33
The conflict between All For One and the various users of the One For All quirks has been carrying on for decades. It has caused the megalomaniac villain to kill every single one of them, many of whom were powerful heroes like Daigoro Banjo, En Tayutai and Nana Shimura. All For One has also reigned as the most powerful villain of Japan for over 100 years, so it’s likely he killed many other heroes during that time.
But there’s another layer to All For One’s wickedness. Since he influenced and/or created most of the villains in the series (like Dabi and Shigaraki), he’s also indirectly responsible for all the deaths that his underlings caused, which means that All For One definitely has the highest body count in all of My Hero Academia.
