The Bat Devil is a recurring antagonist in the manga series Chainsaw Man, a monstrous devil who preys on humans and serves as an early major enemy of Denji and Power.
He is male and is known for his gluttonous appetite for human flesh and blood.
The Bat Devil appears as a gigantic bat-like creature whose body resembles an oversized bat, but with thick, muscular, human-like arms and legs.
His overall presence is brutish and predatory, emphasizing raw power and intimidation.
He is arrogant and cruel, treating humans purely as food and speaking of them as if planning a gourmet course meal.
He casually categorizes humans into “courses,” such as a young girl as an appetizer, a mature, healthy woman as soup, a well-built man as the main dish, and a pregnant woman as dessert.
Before his confrontation with Denji, the Bat Devil had been gravely injured and was searching for a way to heal.
To do this, he took Power’s pet cat, Meowy (called Nyaako in the original), not just as a hostage but as “cat-collateral,” forcing Power to bring him humans in exchange.
In the first part of the story, Power lures Denji to the Bat Devil as a human sacrifice so the devil can drink his blood.
After drinking Denji’s blood and regenerating, the Bat Devil is nonetheless defeated in battle by Denji using the power of the Chainsaw Man.
In the second part of Chainsaw Man, the Bat Devil reappears with a greatly altered appearance, implying he has revived or been reincarnated as a different form.
Driven purely by instinct, he ravenously devours humans and attempts to eat Asa Mitaka and the others who are present at the scene.
Before he can consume Asa Mitaka, the Bat Devil is caught up in the chaotic battle between the Cockroach Devil and Denji.
He is ultimately killed in the crossfire, unceremoniously erased in the clash between devils and Chainsaw Man.
The Bat Devil is voiced by Kenichiro Matsuda in the anime adaptation of Chainsaw Man.
Despite being an early antagonist, he left enough of an impression to be included in official popularity polls.
The Leech Devil is introduced as the Bat Devil’s partner, sharing his dream of devouring all humans.
This shared goal is described as a reckless yet “sublime” dream from their twisted devil perspective.
They are not shown to be constantly together, and they seem to operate independently for stretches of time.
After the Bat Devil is injured, the Leech Devil wanders in search of him, clearly concerned with reuniting and continuing their shared rampage.
Interestingly, in official character popularity rankings, the Leech Devil eventually surpasses the Bat Devil in votes.
In the second poll, the Leech Devil gains about twenty more votes than the Bat Devil, creating a small “reversal” where the partner becomes more popular.
Height: Approximately three times Denji’s height.
Affiliation: None (freelance, unaffiliated devil).
Abilities: Flight, shockwave (air cannon), superhuman strength.
Favorite Things: Human flesh and blood.
First Appearance: Volume 1, Chapter 6 of Chainsaw Man.
Gender: Male.
The Bat Devil’s powers center on mobility, physical strength, and destructive ranged attacks.
He is a straightforward but extremely dangerous combatant, combining brute force with wide-area devastation.
Flight
The Bat Devil uses his enormous wings, which grow from his huge body, to fly freely through the air.
He can carry his own massive weight with ease and move quickly enough to snatch victims or escape when wounded.
His ability to fly makes him a threat not just on the ground but across cityscapes, where he can attack from above.
This vertical mobility also allows him to hold hostages in midair, making pursuit more difficult.
Superhuman Strength
The Bat Devil possesses monstrous physical power, able to lift and throw large objects with a single arm.
At one point, he casually hurls a car using only one hand, showing how far his strength surpasses that of a human.
His limbs, especially his arms, are thick and muscular like those of a giant humanoid rather than a normal bat.
This build lets him crush, grab, and throw humans and vehicles as if they were toys.
Air Cannon Shockwave
One of his signature attacks is a devastating shockwave fired from his mouth.
By pursing his lips and blasting out compressed air, he unleashes a powerful air cannon.
This attack is strong enough to shatter or destroy entire buildings.
The shockwave’s range and destructive force make it a deadly weapon against both humans and other devils.
Although it is described like a sonic or air-based blast, its practical effect is that of a violent, concussive projectile.
This gives him long-range offensive capability in addition to his physical combat potential.
The Bat Devil is the embodiment of devilish arrogance and cruelty.
He views humans as nothing more than ingredients, ranking them based on taste and “menu value.”
He enjoys the idea of eating humans slowly and systematically, savoring each type of victim as part of a “course meal.”
His sadism shows in how calmly he describes killing and eating people as though he were discussing fine dining.
He is also manipulative and untrustworthy.
He bargains with Power using Meowy’s life, then breaks promises without hesitation once he has what he wants.
Despite his brutish demeanor, he is not tactically complex and tends to underestimate his opponents.
This arrogance contributes to his defeat when he underestimates Denji and the power of Chainsaw Man.
In the first part of Chainsaw Man, the Bat Devil functions as a key early villain who tests Denji’s resolve and power.
He forces Power into betraying Denji, only for that betrayal to turn into an important bonding moment once Denji fights to save both Power and Meowy.
By drinking Denji’s blood, the Bat Devil temporarily heals his injuries and regains his strength.
This sets up a brutal battle where Denji, transformed into Chainsaw Man, clashes with the giant flying devil in an urban environment.
Denji ultimately defeats the Bat Devil by using his chainsaws and sheer stubbornness.
The victory establishes Denji as a capable devil hunter and reinforces the series’ theme of brutal, chaotic fights with grotesque devils.
In the second part, the Bat Devil’s reappearance in a new form shows how devils in the series can return in altered bodies or reincarnated states.
His behavior becomes even more primal and instinct-driven, focused solely on devouring humans without complex schemes.
As he tries to consume Asa Mitaka and those with her, he is suddenly dragged into the battle between the Cockroach Devil and Denji.
Caught in this larger conflict, the Bat Devil is killed, almost incidentally, highlighting how even once-menacing devils can become mere collateral in bigger clashes.
The Bat Devil participated in Chainsaw Man’s official character popularity polls.
In the first poll, he placed 73rd, a respectable but modest ranking given the large cast.
In the second popularity poll, his rank dropped significantly to 145th.
During this poll, his partner the Leech Devil actually received about twenty more votes than him, creating a small but notable “role reversal” in popularity.
Though not a main villain, the Bat Devil is remembered for his grotesque design, darkly comedic “course meal” dialogue about humans, and his early impact on Denji and Power’s relationship.
His combination of massive size, grotesque appetite, and arrogant personality makes him one of the early stand-out devils in Chainsaw Man.
