Most Powerful Devils In Chainsaw Man

Chainsaw Man took the world by storm when it ran in Weekly Shonen Jump, and fans around the world are waiting anxiously for the anime adaptation to come out. Its all-out violence and non-stop action stood out from the usual shonen series that normally run in the magazine.

The plot of Chainsaw Man generally revolves around Devils, supernatural beasts that are more powerful depending on how much humans fear them. Devils can contract with humans to lend them their powers, possess corpses to become Fiends, or merge with living humans to become Hybrids. Whether Devil, Fiend, or Hybrid, here are the strongest Devils in the Chainsaw Man series.

Updated May 2, 2025, by Oluwatokiloba Folami: The brutal world of Chainsaw Man relies on fear as the source of power through which devils manifest as humanity’s deepest and darkest fears. They embody what humans fear consciously or subconsciously in their daily lives in the world of Chainsaw Man. Despite the diverse strategies different devils implement to destroy the world, a number of them exceed others in power due to their extensive strength, manipulative skills, or disturbing abilities that pose a challenge to the strongest Devil Hunters. From the Octopus Devil with its cloud of ink to the terror of the Darkness Devil, devils remain symbols of the worst things humanity can imagine.

Future Devil

The Devil Who Dances With Fate

Contracted Humans: Aki Hayakawa, Two Devil Hunters, Thirty convicts

This devil’s contracts remain one of the many out there that cost a lot; known to make contracts that have hunters giving up their lives or body parts, the Future Devil collects based on how much it has foreseen. It’s easy to recognize this devil with its usual chant, “The future rules!”, playful demeanor, and gaping hole in its chest.

The Future Devil’s main ability involves the contractors having to insert their head into the hole in its chest for the Devil to see into their futures. While its abilities are not for the battlefield, it does grant a large advantage to its contractors, giving them an upper hand during battle.

Punishment Devil

The Judgment That Cannot Be Escaped

Contracted Humans: Michiko Tendo (formerly), Yutaro Kurose (formerly)

Summoned only through expensive contracts and ceremonial rites is the Punishment Devil, known for its fearful execution of justice and punishment in Chainsaw Man. During the Gun Devil arc, Makima, together with other contracted devils and the Punishment Devil, engages in a violent off-screen confrontation against the Gun Devil, forcing it to take the form of a fiend.

This devil’s current contractors remain Public Safety Devil Hunters Yutaro Kurose and Michiko Tendo, with the price they paid still unknown. With an appearance of what may be several conjoined humanoid bodies with distorted faces, each carrying a different weapon, the presence of this devil is overwhelming and ominous. Despite its full powers also being unknown, its mere appearance is a sign that punishment will be inevitable.

29

Pain Devil

The Embodiment Of Suffering

This devil took up human form just so she could satisfy her pain-inflicting obsession without having anyone suspect a thing. Known to be a total nutcase, the Pain Devil became one of the most terrifying devils feared by mankind before having a new division made of both hunters and fiends just to defeat her.

Still, this devil’s abilities remain brutal, as she would go to any lengths to inflict as much pain as she can on her victims, refusing to kill them but torturing them to her satisfaction. Her strength, intelligence, and ability to manipulate and torture people still make her feared, so that other devils avoid crossing paths with her.

28

Human Devil

The Devil Who Mirrors Mankind

Considered one of the most intelligent and unpredictable devils, the Human Devil known as Eri takes the role of a Public Safety Devil Hunter for the purpose of her mission to eliminate the Four Horsemen and the Great King of Terror.

Rather than employing brute force to exert power, the Human Devil uses her genius-level reasoning ability to exploit emotions, trust, and sway minds, creating conflicts effortlessly. She strikes by confronting her opponents with the awful side of humanity reflected in them, so they start to question their own very nature. Eri’s view of humanity remains in how she sees humans as the most abominable form of existence, who must be cleansed of their nature.

27

Nail Devil

The Devil-May-Care Companion

The Nail Devil’s main incarnation in the series is that of the mysterious, unnamed Nail Fiend, whose flippant and volatile personality quickly made them stand out as a character. Initially appearing as a partner to Katana Man during his work for Public Safety, they both switch sides to help Asa get Denji out of Public Safety containment.

As with all fiends, the Nail Fiend has enhanced strength and durability, with their speed being especially impressive. Their main weapon is a hammer, which they often use to strike nails into walls or even simply as a blunt weapon. While not every aspect of Nail Fiend’s abilities has been seen, it’s clear that they are a capable, strong devil.

26

Octopus Devil

Yoshida’s Simple Yet Effective Contractor

Contracted Humans: Hirofumi Yoshida

The Octopus Devil is one of many devils offering contracts to Public Safety, with Hirofumi Yoshida being the only contractor known in the Chainsaw Man series. Its full form has never been seen in the main series, but it is shown to have several massive tentacles whenever Yoshida invokes its powers.

The Octopus Devil has only shown its abilities rarely, and only through the contract between it and Yoshida. Yoshida has used the devil’s power to summon tentacles to either attack or defend, as well as fire off a blast of ink to blind his foes. While the Octopus Devil has yet to prove itself as a powerful devil, it also has yet to truly show its full power.

25

Shark Devil

The Hyperactive Fish-Man

The Shark Devil appears in the Chainsaw Man series as the Shark Fiend, Beam, a Public Safety Devil Hunter from Division 4. A fan of Chainsaw Man, Beam is a reliable ally to Denji during the events of the Public Safety Saga, acting as his partner while Power was out of action.

As the Shark Fiend, Beam’s main power is to transform parts of his body into those of a shark. He can even completely turn into a shark, as well as various shark-based powers, such as the ability to swim through solid objects and an enhanced sense of smell.

24

Violence Devil

The Paragon Of Unleashed Power

The Violence Devil appears as the Violence Fiend Galgali, a member of Public Safety’s Division 4. Due to his extreme power, Galgali is forced to wear a mask that constantly emits poison, which weakens him slightly. Though he is the embodiment of violence, he is a surprisingly kind and amicable fellow who gets along with others easily.

As the Violence Fiend, Galgali’s physical combat abilities are incredibly powerful, matching the power of true Devils even though he incarnates as a weaker Fiend. His specialty is hand-to-hand combat, and he can transform parts of his body into his true form for even more power.

23

Zombie Devil

The Infectious Plague

Contracted Humans: Various Yakuza

The Zombie Devil gains the distinction of being the first devil that Denji defeated as Chainsaw Man. Having made a contract with the yakuza that employed Denji to kill devils, the Zombie Devil has an extreme hatred for Devil Hunters and hopes to kill any he finds.

The Zombie Devil turns humans into zombies, even those who are contracted to receive his power. Humans who are bitten by zombies become zombies themselves, which can turn even one zombie into a deathly situation. While the Zombie Devil himself can do little in battle, his power to turn humans into zombies is incredibly potent.

22

Spider Devil

The Silent Slaughterer

Though Princi appears to be a Fiend due to her human-like appearance, her spider legs reveal her true identity as the Spider Devil. Princi is a member of the Public Safety Division and is a Devil that is surprisingly loyal to Makima. While her role in the story is fairly small overall, her capabilities in combat cannot be underestimated.

Princi’s powers are related to spiders, allowing her to climb walls and submerge and emerge from the ground. Her main mode of attack is her spider legs, which can easily impale a foe with a single attack. She can also use her zipper to summon Makima to wherever she is, though whether she can do the same for anyone else isn’t currently known.
