Hell, the realm of Devils

A mysterious and bizarre race of supernatural predators that menace the world of Chainsaw Man, Devils (Akuma in Japanese) are Anthropomorphic Personifications of a specific fear found in the human mind, ranging from ridiculous phobias to ancient terrors that have haunted men since time immemorial.

Devils

In General

Actually a Doombot: Contracted Devils like Kon can manifest aspects of themselves at the behest of their contractors that won't cause them long-term harm if they're destroyed. They can be summoned fully, allowing them to exert their full strength, but they can be killed when they're out in the open in this manner.
Alien Blood: Devil blood is bright purple. This is only shown by a few color pages in the manga, but in effect regularly in the anime.
Always a Bigger Fish: The Primal Fear Devils are The Dreaded among their own kind, to the point that Pingsti, a Fiend, asks Quanxi for permission to kill herself before it can kill her itself. Considering the monstrously brutal Curb-Stomp Battle it inflicts on Quanxi's team and Public Safety, it's not hard to see why. It's implied the Four Horsemen, powerful Devils themselves, are unable to kill them; Makima can barely fight back against the Darkness Devil and instead uses Tolka to make a contract with the Hell Devil to get out of Hell rather than fight it, and Yoru (who it should be noted is already weakened after Pochita devoured most of her original body) recognizes the threat the Falling Devil poses and runs as far away from it as possible while stating fighting the Falling Devil is suicide. And in Part 2, it's shown that even the Primal Fear Devils stand below the Death Devil in terms of the demonic hierarchy.
Ambiguous Gender: The majority of Devils seem to have No Biological Sex and just use pronouns for convenience. Many of the more intelligent and/or humanoid are typically referred to with "he" and "she" while the more hostile and monstrous ones are referred to with "it".
Anthropomorphic Personification: Each one represents the fear of a specific thing or concept, with the level of their strength being directly proportional to how feared the idea they represent is. Though how literally "anthropomorphic" they are varies wildly; many are extremely animalistic and show no signs of sapience.
As Long as There Is Evil: Because Devils are the physical embodiment of human fears, they can never truly be killed as long as people continue to fear the concept which bring them into existence. However, when they are functionally "killed" in the human world, they reincarnate in Hell with all their memories from the past life gone, so they still die as individuals.
Beauty Equals Goodness:
- The more humanlike a devil is in appearance, the more akin to a human their thoughts, mind, and belifes will be. However, this doesn’t necessarily mean these Devils are actually good; Angel is non-hostile but unbelievably apathetic, even toward people's lives, and Makima—despite taking the shape of a beautiful woman and having very human motivations—is one of the most monstrous characters in the story.
- Played straighter with the non-humanoid devils, as the fundamentally good individuals (Pochita, Bucky, and possibly Guilly) look strange, but in a silly or cute way, rather than horrifying or intimidating. Interestingly, the Muscle Devil looked similarly harmless until it revealed its true colors and grew many bizarre and monstrous features.
Better to Die than Be Killed: Devils are terrified of running into those created from primal fears, because they tend to make their victims suffer painfully and gruesomely at length.
Bishōnen Line: Played with; all of the nearly-human devils seen so far are quite powerful, but they're the minority even among the highest echelons. There are plenty of incredibly powerful devils that are only broadly humanoid. One of the most powerful Devils in the series, Gun, is a towering skyscraper-sized monstrosity, but it's quickly caught off guard and taken out in an ambush by Makima, who appears identical to a beautiful human woman. She herself, in turn, lands one good hit in but is clearly vastly outclassed by the Darkness Devil, who's "only" about ten feet tall (compared to the colossal Gun Devil) and takes the form of a many-armed, pterodactyl-headed walking totem pole of human corpses.
Body of Bodies: Reflecting how they originate from mankind, it's very common for Devils to have bodies at least partially comprised of masses of a human bodypart. One example being the Snake Devil, which has a beak formed from hundreds of folded-together human arms.
Cannibalism Superpower: Other than becoming more feared, Devils can grow in strength by consuming the flesh of stronger Devils. Multiple Devils that embodied fairly non-threatening concepts (such as Fish) became genuinely dangerous after swallowing a piece of Gun.
Carnivorous Healing Factor: Devils and fiends can heal from injuries by eating human flesh and viscera.
Cast from Lifespan: A common price that Devils ask in exchange for their power and/or service is time from the contractor's remaining lifespan, as seen with the Curse, Future, and Gun Devils.
Deal with the Devil: The primary source of superpowers in Chainsaw Man's setting is making a contract with a devil, allowing one to either borrow some of their power or outright summon them at the cost of... well, whatever the devil in question wants, but it's typically a body part, one of your senses, or time from your life. In addition, contracts are Serious Business for devils; they never offer one lightly, and they will always follow it to the letter. Even the godlike ones borne from primal fears like the Darkness Devil will still give what they promised even if what they were paid slips through their hands. However, that doesn't necessarily stop them from engaging in Exact Words or Loophole Abuse if they're particularly malevolent, so making a contract is risky unless you know what you're doing. And even if a devil doesn't betray their contractor, they almost always demand payment upfront, which won't be refunded if the devil dies or their power simply isn't enough to win.
Demon of Human Origin:
- Devils are born of and empowered by human fear, making their relationship with mankind essentially parasitic: despite requiring humans to exist in the first place, most Devils torment and bring harm to their creators to further their own power.
- Devil contracts that transform the user can in some cases outright turn humans into "pseudo-devils" that share devils' instinctive desire to kill and eat humans.
Demonic Possession: In contrast to most modern interpretations of demons, possessing a human is actually a last resort. Taking over a human corpse (becoming what's known as a Fiend) will severely deplete a Devil's power and is something they only do willingly when the alternative is death.
Devil, but No God: They’re more malicious predators than embodiments of evil, but they have no benevolent counterpart, just a very small minority that think favorably of humans.
Dirty Coward: Valor is rare in Devils, who will instinctively hide from enemies and would-be victims if they believe engaging with them will be difficult. They can be tempted into doing so if offered a juicy enough contract or by reminding them that they're still under one they made when they thought they had better chances.
A Dog Named "Dog": Almost all of them just refer to themselves by the name of the fear that created them, though a few especially intelligent Devils (such as Yoru, Pochita, Bucky and Makima) are willing to come up with personal names.
The Dreaded: Among Devilkind, there are Devils who bear the name of Primal Fears, representing the oldest fears known to man. Described as "transcendent" by Pingsti, these Devils have never experienced death at any point in their life and have lived for countless years. These Devils are not just feared by humans, but also other Devils as well. In Chapter 63, when members of Public Safety and Quanxi's team are trapped in Hell, the respective groups' Fiends Freak Out when they sense the Darkness Devil, a Primal Fear, watching them. A similar case happens in Part 2 and reiterates how dangerous these Devils are: Yoru, the War Devil and one of the Four Horsemen, immediately books it when the Falling Devil manifests in front of her, knowing she'd die if she tried to fight it.
Dub Name Change: Partially; they're called "akuma" in Japanese and "devils" in English. However, the term "devil hunter" is used even in Japanese.
Eldritch Abomination: Most of the time, the term “devil” applies to some kind of creature or being from the fiery underworld. That’s not the case here. Not for the devils or Hell even. Instead of being merely demons, the devils are more akin to tulpas or lovecraftian entities empowered by the human mind. As long as those fears exist, so too shall they. And if they're erased from existence, reality is reshaped so that the thing they represented the fear of never even existed in the first place.
Eldritch Location: Hell, appropriately enough. Despite the intimidating name and various nightmarish depictions in real-world media, Hell is shown to be a grassy plain with doors floating in the sky, with said doors implied to correspond to specific Devils.
Emotion Eater: Devils eat all the fear humanity associates with the Name they bear, as well as the fear humans and other Devils feel towards them directly.
Enemy Civil War: Some specific devils are friends or lovers, and may resent devil hunters broadly for opposing their kind. But in most cases, they care as little about each other’s lives as they do the lives of humans: Absolutely none of the ones contracted to Public Safety show any problem with their powers being used to cut down other Devils. If the reaction Quanxi and Public Safety's Fiends have to sensing Darkness looking at them is any indication, it's very common for the ones living in Hell to prey on each other.
Evil Is Visceral: Everything to do with Devils is overloaded with Body Horror: All of them share the ability to heal and empower themselves by consuming blood and flesh. And most, even ones represent things like weather phenomena or the law, take forms at least partially composed of grotesque viscera.
Fisher King: If a Devil is erased by Pochita's Abstract Eater ability, the Name they bear ceases to exist as well. This has happened with, among other things, Nazism, all of World War II, AIDS and nuclear weapons.
Healing Magic Is the Hardest: Devils heal themselves by drinking blood, but they're not exactly interested in healing humans. The only known methods involve becoming at least partially demonic yourself, a drastic step that's rarely available. Santa Claus needed a deal with one of the most powerful devils in existence to repair her dying body, though it also came with an especially powerful Healing Factor.
Heal It with Blood: Drinking human or Devil blood heals their injuries.
Hell: They apparently originate^* from an Eldritch Location by this name and spend every other reincarnation there. Its interior resembles a calm grassy plane with a sky comprised of an infinite number of doors that seemingly correspond to one Devil. It's called Jigoku in the original Japanese and is based on the Buddhist idea of other realms you cycle between from life-to-life. Notably, this only seems to apply to devils; there's no evidence it also serves as a human afterlife.
Hoist by Their Own Petard: The fear of other members of their kind can strengthen a Devil just as much as the fear of humans, one example being how Pochita’s status as “the Devil all Devils fear” having made him the World's Strongest Man.
Human Sacrifice: It's possible for a contract to take an entire human life as payment, sometimes several. Sacrificing oneself is simple enough, but using someone else against their will seems to require a victim who recognizes the authority of the contractor, such as from parent to child or from a government to its citizens. That or some kind of mind control.
The Hunter Becomes the Hunted: Because even normal humans like Kishibe can fight back against them, Devils are extremely resentful of Devil Hunters for getting in the way of their rampages, with some even devoting much of their time to killing as many as they can before they have a chance to take them down.
I Cannot Self-Terminate: While Devils can knowingly run headfirst into dangerous situations, they appear to be unable to take their own lives. Even the Eternity Devil, driven to suicide by the agony Denji inflicted on it during their battle, had to hand its heart to Denji to destroy.
I Know Your True Name: Makima describes Devils as being born into the world bearing the name of one of humanity’s fears and that this name is the heart of their being. A Devil’s appearance, personality and abilities are all determined by how their Name is perceived in public consciousness, and Chainsaw Man’s Abstract Eater ability can kill Devils permanently because it erases this Name from history.
Inhumanable Alien Rights: Devils vary greatly in how humanoid, intelligent, or dangerous they are, but are never recognized as having rights by any government. This extends to the point Weapons Humans lose all their human rights just for integrating a devil into their body despite maintaining the same personality.
Inverse Law of Complexity to Power: Zig-zagged; the most powerful Devils are usually the ones that embody more vague, abstract fears, as they'll be strengthened by a greater amount of people, most obvious with the Darkness Devil. But there are exceptions going both ways: Guns, bombs, and chainsaws are fairly complicated and recent inventions, but their Devils are among the strongest because of how humans think of them.
Invincible Villain: The Primal Fears are so ludicrously powerful that their own kind and Fiends fear them so much, they would much rather commit suicide than stand in front of one or catch their attention. Although only two of their number have shown up, the heroes either suffer a horrific Curb-Stomp Battle (Darkness Devil) or try and run as far away as possible (Falling Devil). Fighting them is not an option.
It Can Think: Humanoid devils are consistently sapient. Otherwise, how intelligent or self-aware an individual Devil is appears determined completely at random, and seems to vary even from incarnation to incarnation. For instance, the Bat Devil was completely lucid and capable of very human behaviours, like having a girlfriend, during his first appearance, yet the incarnation seen in Part 2 appeared to be little more than a mindless, animalistic monster driven solely by hunger. Given that Devils are stated to lose their memories after they're killed, it's entirely possible that a degree of sentience is also lost along the way.
Loophole Abuse: A common way that Devil contracts can fail is that if a Devil is overpowered or even killed in its given task, the humans they are contracted with are not reimbursed despite their failure. This isn't a technicality that Devils tend to exploit though as they dislike being injured or killed, and even a failure they survive makes people fear them less.
Magically-Binding Contract: When a devil forms a contract, it must follow the terms or die. This notably only works when it's a deal explicitly referred to as a contract, and Devils can only make them with humans and other Devils, not Fiends.
Mars Needs Women: As much as devils usually hate humans, a few of them have found them sexually attractive. Disturbingly, two of the three (Fox and Leech) aren't at all humanoid and the latter is just as likely to kill them. The third (Angel) formed a genuinely loving romantic relationship with a human woman, though it didn't end well.
No Ontological Inertia: The effects of a Devil’s power generally fades away when they die. The main exception seeming to be if they have a Contract that specifies something as happening post-mortem.
Not Always Evil: The vast majority of Devils are savage, chaotic beings that desire to make humanity suffer (either by attacking Earth or taking away the things important to them through Contracts). Yuko turning into a devil induces a murderous instinctual urge that has to be actively held back. Yet several Devils, such as Pochita, Angel, and Bucky, display an ability to empathise with and even aid humanity of their own volition. It's not clear how or why they differ from other Devils, but its implied to stem from gratitude towards humans who take mercy on them at their most vulnerable.
Odd Job Gods: A Devil exists for every possible fear, even fears that really feel like they shouldn't exist in the first place; you really have to wonder who in the world is scared of tomatoes and marshmallows, for instance. As very few people share these fears, these Devils tend to be the weakest; Denji made a living before becoming Chainsaw Man by hunting the likes of the Marshmallow Devil and Tomato Devil (despite missing several vital organs and being fatally ill), Power was able to kill the Sea Cucumber Devil in one hit, and the Chicken Devil admits they'd probably be killed by a stray cat if they ran away from the high-school currently taking care of them.
Kobeni: (Seeing Violence Fiend holding a twisted mass of eyeballs and tentacles) What kind of devil do we report this as?
Violence Fiend: Grapes?
Our Demons Are Different: Living personifications of all possible human phobias whose power is tied to how much humanity fears the concept they embody. While their appearances and capabilities vary wildly depending on the fear the Devil was born from, all of them share the ability to heal severe wounds or empower themselves by consuming the blood of either humans or stronger Devils and to reincarnate upon death at the cost of their identity.
Past-Life Memories: They appear capable of recalling small fragments of previous lives. Most notably, all of the devils working for Public Safety remember and fear the sound of the Chainsaw Devil revving up.
Primal Fear: As creatures that draws strength from fear, the Devils who represent humanity’s most instinctual fears are naturally among the strongest beings in existence. The first such Devil, Darkness, effortlessly tears through some of the most capable Hunters in the entire world, including even Makima. Implying not even most of the Four Horsemen save for Death match their might.
Pingtsi: Far beyond here... Devils far, far more dangerous than some Gun Devil... the Devils with the names of the primal fears are watching us... They're the transcendent... Devils who have never once experience death.
Reincarnation: Killing a Devil on Earth causes it to reincarnate in Hell, with the reverse also being true. Though it comes at the price of their every memory.
Aki: You're a devil. You don't remember hell?
Angel: Do you remember your mother's womb?
Rule of Scary: In-universe, Devils are strengthened by the fear their namesakes inspire, regardless of how dangerous or harmless that namesake actually is. Chainsaws, for instance, are realistically awful as a weapon, but Pochita (the Chainsaw Devil) is very powerful in spite of it because they're also terrifyingly loud and can inflict gruesome wounds on the human body.
Sealed Inside a Person-Shaped Can: Some devils lay dormant in their contractor's body while waiting for them to use their power. This puts the devil in more danger (though it's not clear if they'll die if the contractor does), but lets their power be accessed even when a remote summoning would be cut off, as happened when Aki couldn't use the Fox Devil inside the Eternity Devil's hotel.
Shapeshifter Baggage: Their ability to heal is limited by drinking blood, but can regenerate mass outsize to what they consume. The blood the Bat Devil squeezes out of Denji lets him regrow an arm much larger than a whole human body. Denji in turn regenerates that with just a mouthful of the Bat Devil's blood. Devils can also grow larger just from eating fear.
Stupid Evil: Devils love causing destruction and carnage, so even Devils that can attack remotely like Eternity or Typhoon will inevitably show up in person to wreck havoc, making their presence known to hunters.
Summon Magic: One common Devil contract simply lets you summon the Devil in question or some part of it; this is how the Fox Devil is used.
Super-Empowering: Another form of contract lets you borrow the Devil's powers directly, as seen with the Future Devil, or outright transform into it, like the Justice Devil and (possibly) the Doll Devil. Extensive use of the latter can lead to a permanent Power-Upgrading Deformation or even turn a human into a "pseudo-devil".
To Serve Man: All devils can heal by drinking human blood, but many of the more monstrous ones consume more than they need to because they like the taste.
Super-Senses: Devils can detect and track the scent of humans and blood from a given distance. The Bat Devil in particular can differentiate between men and women from a mile away. Denji later deduces that Makima primarily remembers people via scent.
Tulpa: Created by human fears, each one embodying a specific source. Interestingly, unlike most Tulpa, Devils seem to be metaphysically linked to the concept they embody, as when a Devil is eaten by Chainsaw Man, whatever inspired the fear they embody ceases to exist entirely.
Wants to Be Hated: The majority of Devils' behavior center on a desire to become more feared because it makes them stronger. Humanity becoming scared of a Devil specifically can lead to them becoming more afraid of what that Devil represents^note, creating a feedback loop they can ride to extraordinary power.

Debuted in Part 1

Chainsaw Devil

See the Main Characters page, but be warned that all spoilers are unmarked

Tomato Devil

Voiced by: Hinata Tadokoro (Japanese), Kristian Eros (English)

The first antagonistic Devil to be shown in the series and the last Devil Denji kills while in debt to the Yakuza prior to his meeting with the Zombie Devil. Representing humanity's fear of tomatoes, it was killed by Denji and its corpse later sold to the black market to pay off Denji's debt.

Curb-Stomp Battle: It's a weak Devil compared to others later seen in the manga and anime, so much so that Denji kills it offscreen while still fully human without much trouble as he's shown standing over its corpse without a scratch on him.
Eyes Do Not Belong There: Has several eyes dotted across its main body.
Resurrective Immortality: Denji's familiar enough with the Devil that he warns the old man in charge of the yakuza to dispose of the Tomato Devil's seeds, as it can use them to revive itself.

Zombie Devil

Voiced by: Kōki Miyata (Japanese), Linda Young (English)

https://static.tvtropes.org/pmwiki/pub/images/images_650.jpg

The Devil representing humanity's fear of zombies. When the Yakuza that Denji was indebted to attempted to make a deal with it to gain more power, they were turned into zombies as a result. It then used its new minions to hack Denji and Pochita into pieces, causing Pochita to sacrifice himself by becoming Denji's heart and turning Denji into Chainsaw Man.

Ambiguous Situation: Makima revealing control of it in the climax of Part 1 suggests the zombies Akane and Samurai Sword got came from her, though it's never made clear one way or the other. Given that it was also Not Quite Dead by its second proper appearance and Makima happened to be first on the scene, it's possible that Makima may have also orchestrated the initial incident.
Ain't Too Proud to Beg: While it's quick to taunt Denji with his army of zombies, the moment his new demonic form cuts out one of its eyes, it quickly starts begging for mercy and for Denji to keep away, while throwing its slaves at him in a pathetic attempt to defend itself.
Back for the Finale: It returns in the Control arc under Makima's control, its power being used to raise an army of undead.
Card-Carrying Villain: The Zombie Devil itself called the yakuza morons for trusting something as evil, dangerous, and self-serving as a Devil. Admittedly, it kinda has a point about Devils, especially one called the Zombie Devil, not being the kind of being that any sane person would willingly associate themselves with.
Even Evil Has Standards: Expresses disgust at how how greedy and idiotic it was for the Yakuza to think that they would get to use its power. This speaks volumes about what kind of people the Yakuza really are.
Grievous Harm with a Body: During their first fight, it threw its zombie at Denji.
Hypocrite: Calls Denji's revival disgusting, in spite of its skillset doing the same thing.
Metaphorically True: Offers to give the yakuza Denji owes money to its power. The Yakuza thinks this means it'll help them expand their business. In fact it meant it'll give the yakuza a taste of its power... turning them all into its mindless zombie slaves.
Mook Maker: Can produce zombies that act as an extension of its power. While it turns Denji's boss and his closest associates into zombies, the yakuza group working under Katana Man have kept a bunch made out of people behind on their loans to act as meatshields against Division 4's assault.
Names to Run Away from Really Fast: Just say it slowly. Zombie. Devil. Doesn't exactly sound like the kind of being you'd want to hang around much, would you? Unless you're the elderly Yakuza boss and his subordinates who Denji grew up working for, who decided that making a contract with someone called the Zombie Devil actually sounded like a great idea apparently.
Necromancer: Can turn living people into zombies and raise the dead.
Not Quite Dead: Aki later reveals that a Devil's power has No Ontological Inertia. In spite of being split in half, its zombies are still active, hinting that it's not actually as dead as Denji initially assumed and later returns under Makima's control. As further evidence, it looks the same as when it first faced Denji, indicating that it never reincarnated like Devils should whenever they die.
Our Zombies Are Different: Has dominion over zombies resembling those traditionally seen in popular fiction (which otherwise don't exist in the story's setting) to contrast the other ways characters can come Back from the Dead such as becoming Fiends or Hybrids.
She's a Man in Japan: Downplayed; the Zombie Devil's gender is uncertain, but it has a (high-pitched) man's voice in Japanese and a woman's voice in English.
Species Loyalty: Their stated reason for having Denji killed was due to his job of killing and chopping up devils and when he becomes Chainsaw Man, they assume he's Pochita whose possessing his body and briefly attempts to use this to convince them not to fight since he's one of them.
Starter Villain: The Devil that gets Denji and Pochita killed, leading to them to fuse into Chainsaw Man.
Villainous Breakdown: Descends from being very eager to kill Denji and Pochita to screaming at them to stay away from it when they transform for the first time.
Zombie Devil: What in the world are you? Did that runt of a Devil you were with take control of your body? […] Stay away! Don't you dare budge from that spot! Stay where you are, you freak! Go awaaaaay!

Muscle Devil

https://static.tvtropes.org/pmwiki/pub/images/0002_014.png

A harmless-looking devil that's seemingly befriended a little girl.

Adapted Out: The anime skips Denji's encounter with it, presumably so Aki and Power can be properly introduced before the end of the second episode. His would-be victims are protected by Denji from the Bat Devil instead. It does however, briefly appear as a cameo in the third ending.
Bait the Dog: Muscle pretends to be a harmless Devil that has befriended a human girl, much like Denji's relationship with Pochita. It's a complete lie meant to lull Denji into lowering his guard.
Bitch in Sheep's Clothing: Pretends to be an adorable, harmless devil who saved a little girl from her abusive dad. Once Denji falls for its trap, it reveals it controlled the girl into saying all that and is an evil creature who intends to kill Denji and mutilate the girl for fun.
Puppeteer Parasite: Muscle can control its victim's bodies by attaching to them.
Would Hurt a Child: Denji is Forced to Watch when it starts to "have some fun" with the kidnapped girl by horribly contorting her face. Luckily, Denji kills it before any permanent damage is done.

Bat Devil

Voiced by: Ken'ichirou Matsuda (Japanese), Gabe Kunda (English)

^{Part 2 Appearance}

A devil that kidnapped and threatened to kill Power's pet cat, Meowy, unless she brought him a human to regenerate his wounded wing.

Adaptational Dumbass: Justified; the Bat Devil reappears in Part 2, but as it's newly reincarnated, it isn't as strong or as intelligent as when Denji first met it.
An Arm and a Leg: One of his arms/wings was cut off by a human, preventing him from flying. He hid himself in an abandoned house until Power could bring him a human whose blood he could use to regenerate his lost limb. Not soon after drinking Denji's blood to regenerate, Denji slices the same wing off again as Chainsaw Man.
Arc Villain: He is the main villain of the Bat Devil Arc.
Back for the Dead: He's seen reincarnated in Part 2, but lasts all of one chapter before getting fatally caught in Denji's fight with the Cockroach Devil, which incidentally saves Asa and Yuko after the Bat Devil tried to swallow them whole.
Bat Out of Hell: A fairly straight-forward Devil, a bat larger than a human and capable of swallowing a person whole.
The Bus Came Back: After being completely absent from Part 1 after his initial death, he eventually died in Hell and came back to Earth once more, attacking people in buildings at the beginning of Part 2.
Flight, Strength, Heart: Most of the powers Bat displays (flying, immense strength, swallowing people in one bite) are abilities one would expect to belong to a giant monstrous bat… But for some reason he also has the power to grow a fully functional cannon out of his mouth. Given it fires sonic waves, it seems to be a warped reference to the concept of echolocation.
I Gave My Word: While it wasn't a formal contract, and Denji's skeptical over the cat's survival given how much time has passed since she was kidnapped, the Bat Devil makes sure to keep Meowy alive as he waits for Power to bring him a human to eat, and only tries to kill them both when he was displeased by the flavor of Denji's hybrid blood.
I Have Your Wife: Kidnapped Power's pet cat in order to get her to bring him a tasty human so he could use their blood to regenerate his amputated wing.
I Lied: Swallows both Power and her cat, after she upholds her end of the bargain.
Just Eat Him: All the named characters it eats are Swallowed Whole, letting them survive when they're released in one way or another. The unnamed woman it eats isn't so lucky, as it bites her in half before swallowing.
Normal Fish in a Tiny Pond: By Part 2, Denji is so much more skilled and experienced that he kills the new Bat Devil by accident while fighting the much stronger Cockroach. But when Asa and Yuko confront it when Yoru's powers are unavailable, they're immediately forced to run for their lives, because it's still an elephant-sized monster.
Picky People Eater: Thinks Denji and Power's blood tastes disgusting, and mentally plans to get more from specific demographics of people (young virgins, old women, children, etc.).
Starter Villain:
- While Denji has fought Devils beforehand, the Bat Devil is the first one to pose a real threat to him and the others.
- Assumes this role again at the beginning of Part 2, being the first demon faced by Asa and Yuko as members of their highschool's Devil Hunter Club.
Took a Level in Dumbass: In Part 1, Bat Devil is humanly intelligent and quite arrogantly talkative. The reincarnation seen in Part 2 seems completely bestial and unable or unwilling to speak.
Villain Forgot to Level Grind: Justified by having died and reincarnated, but he's just as threatening as he originally was... to Asa and Yuko. Denji, on the other hand, has grown exponentially more powerful and literally kills him on accident by bodily hurling the Cockroach Devil in his general direction, which crushes him.

Leech Devil

Voiced by: Yuuko Tachibana (Japanese), Corey Pettit (English)

The girlfriend of the Bat Devil who shows up to avenge her slain lover.

Arc Villain: She, alongside Bat Devil, is one of the main antagonists of the Bat Devil Arc.
Combat Pragmatist: Lops off one of Denji's arms before making her presence known to the protagonist.
Diabolus ex Machina: She shows up after Bat is killed and Denji is already too tired and out of blood to keep fighting to cause more trouble. Her appearance mostly serves to introduce Kon.
Even Evil Has Loved Ones: Bat's lover, and quite unhappy when she arrives to find him slain. Though, that doesn't stop her from flirting with the guy who killed him and offering to let him live.
Mars Needs Women: She thinks (human form) Denji is cute, enough to consider letting him go for killing her boyfriend. Said boyfriend is a giant bat, so she may be an outright Extreme Omnisexual.
Multiboobage: Played for its full Body Horror, to boot. Leech has rows of saggy, disturbing-looking breasts.
Non-Mammal Mammaries: She has six breasts despite not being based on an vertebrate, much less a mammal.
Non-Mammalian Hair: Her most humanly feminine feature is a head of long black hair.
Unholy Matrimony: She says that she and "Batty" were involved and had a dream to eat all of humans together, even though they knew it would never come true.
Villain Ball: Snipes an unwitting Denji's arm rather than his heart or head because she finds him handsome despite how he killed the Bat Devil.
You Will Be Spared: Despite the fact that Denji killed her boyfriend, the Leech Devil offers to let him escape with his life because she thinks he's cute. When she confirms she has no plans to spare Power and Meowy, Denji gets the chainsaws out and she rescinds her mercy.

Fox Devil

"Kon" / Fox Devil

Voiced by: Yuko Kaida (Japanese), Natalie Van Sistine (English)

https://static.tvtropes.org/pmwiki/pub/images/kon_5.png

The Fox Devil. Holds contracts with quite a few members of Public Safety.

Achilles in His Tent: Refuses to answer Aki's summons, after being used against the Katana Man.
Aloof Ally: Kon's benign towards humans, and happy to work with the Public Safety Devil Hunters. That said, you feed it a demon that tastes disgusting, it will straight up void the contract and abandon you. Aki's summonings falling on deaf ears means its pissed off he fed it Katana Man, a hybrid, neither human or devil. Later the Vice Captain of the Second Division HQ summoned the Fox Devil to try and swallow Reze, but Kon immediately hated the flavor and left again.
Ambiguous Situation: It's unclear if "Kon" (the onomatopoeia for a fox barking) is actually the Fox Devil's name or that’s just a verbal command needed to summon it, as Public Safety never use the word in another context.
Awesome, but Impractical: Fox is a fairly powerful Devil willing to Contract for the price of feeding it small amounts of skin or hair. But it's also temperamental enough to leave someone to die against a powerful opponent just because it didn't enjoy their taste.
Asian Fox Spirit: A fox demon employed by the Japanese government. In a strange inversion of the Foxy Vixen aspect, the Fox Devil looks every bit a ragged animal, but appreciates handsome human men and gives them exclusive access to its most powerful ability.
Comically Small Demand: Compared to the hefty prices demanded by other Devils, Kon will answer a contractor's summons in exchange for letting it eat a bit of skin small enough the resulting injury can be treated with bandages. According to one of the omakes, it even lets Aki get away with making his topknot as the offering. On the other hand, you get what you pay for, as the Fox Demon will quickly ditch its contractors if it doesn't like the scenario it's been summoned to, as Aki experiences more than once.
Deal with the Devil: Summoning Fox seems to be the most common Contract among Public Safety agents: In addition to Aki and Arai, two separate Red Shirts summon it during the Bomb Woman and International Assassins arcs.
Early-Bird Cameo: In the anime, Aki is shown using it in the abstract animation of the third ending before it's properly summoned in the proceeding episode.
Female Monster Surprise: The Fox Devil's gender isn't visibly apparent, and in the English manga is referred to as "it", though it is implied to be attracted to (human) men. The anime gives it a woman's voice and the subtitles use "she/her".
Fighting a Shadow: Aki states Devil Fox's physical body resides in Kyoto, but its contractors can summon copies of its claws and head at any distance, that can be destroyed without harming Kon itself.
Foul Fox: A Devil born from the fear of foxes and a capricious dick prone to abandoning its contractors if they feed it something not to its tastes.
Kaiju: Kon's full body hasn't been seen, though judging its manifesting claws and head alone, which take up a small office block alone, it's implied to be a gigantic being.
Mars Needs Women: For some reason Fox only allows Public Safety agents to summon its head if it considers them "handsome", the only specified one being Aki, and Himeno describes it as being a sucker for looks.
Monstrous Cannibalism: Fox seems to be working for Public Safety primarily because it enjoys snacking on other Devils more than it does humans.
Nominal Hero: Aki describes Kon as "friendly with humans," but it seems to just see other devils as more desirable or available prey. What sympathy it has for humans is limited to a strange physical attraction to some, and it's very petty even to them.
Perspective Magic: Contractors mime attacking their target with a hand puppet of part of the Fox Devil's body, summoning the part in place to actually attack.
Picky People Eater: The Fox Devil has no qualms about eating other Devils, but hybrids like Katana Man taste so foul to it that it immediately nullifies a contract after biting them.
Screw This, I'm Outta Here: Kon's very prone to bail whenever used against an opponent it considers unappetising, doing so against both Katana Man and Bomb Woman.
Token Heroic Orc: Kon is noted as being friendly to humans, although it is fickle and might refuse to answer summons if it doesn’t like what its contractors have been making it fight.
Villainous Glutton: Seems driven entirely by its hunger for Devil flesh, as it'll instantly void a Contract if they feed it something it finds unappealing.
The Worf Effect: Fox is cut apart by Katana Man in the latter's first appearance, just to drive home that Katana Man is a serious opponent.

^{Part 2 Appearance}

The Devil representing humanity's fear of eternity. Empowered from ingesting a piece of the Gun Devil, it turns the eighth floor of a hotel into an impossible loop where time has stopped, trapping Devil Hunters from Special Division 4 when they go to investigate.

Arc Number: The devil traps the Public Safety Devil Hunters on the 8th floor at precisely 8:18, likely in reference to how the symbol for the number eight is a ∞ symbol turned sideways. This motif is abandoned for its second appearance.
Arc Villain: It serves as Public Safety's target for the aptly named Eternity Devil arc. It's the first devil fought in connection to the overarching story arc of the Gun Devil, and it's also the first enemy to not be defeated in a complete Curb-Stomp Battle; in the anime, the Zombie, Bat and Leech Devils are quickly killed off in their introductory episodes, while the Eternity Devil's arc lasts for three. It plays this role again in Part 2, when it returns to bedevil Asa and Denji when they're at the aquarium on Fami's orders.
Awesome, but Impractical: Other than its time-stop, Eternity’s primary ability is spawning an infinite mass of meat it can remotely manipulate. This power seems very intimidating at first glance… but it later turns out that Eternity feels all the pain of every injury the mass suffers, a weakness Denji takes full advantage of to subject Eternity to three days worth of agony.
Back for the Dead: While it lasts for a few chapters, its reincarnation in Part 2 is killed almost immediately after making a proper physical appearance.
The Bus Came Back: It seemingly returns once again in Part 2 at the behest of Fami, trapping Denji, Asa, Yoshida, and the Devil Hunter Club in an infinite loop of the aquarium they’re in so that Asa will be forced to turn Denji into a weapon in order to escape.
Call-Back: Its first appearance had it trying to convince Special Division 4 to hand Denji over under threat of starvation. Fami as the embodiment of that hunger has the next Eternity Devil trap Denji and Asa so that the latter will become hungry enough to abandon her morals.
Cruel and Unusual Death: It spends three days being tortured with chainsaws before it finally offers up Denji its heart to just kill him already and be done with it.
Deal with the Devil: It offers to make a contract with Special Division 4. It'll let them leave the hotel if they give it Denji's heart.
Didn't Think This Through: Something Denji exploits to his advantage. It has the power to heal itself forever, can trap its targets in an Unnaturally Looping Location eternally, and can never be killed unless it intentionally exposes its heart. The problem is, it apparently can't leave said endlessly looping location, and in the case of the blood-powered Denji, once he stops running from it and starts fighting, he discovers that it accidentally provided him with an infinitely regenerating source of fuel he can use to keep shredding it to pieces indefinitely. And the Eternity Devil has just trapped itself in the same enclosed space with said torturer. Denji puts it best:
Denji: I cut you and I bleed. I drink that blood and heal. I'm a fucking perpetual motion machine!
Drama-Preserving Handicap: The Eternity Devil doesn't have to leave any part of itself in its traps, and if it doesn't, they're seemingly inescapable. Division 4's saving grace (unlike the first team sent in) was that the devil sent a piece of its body inside to obtain Denji's heart. Its reincarnation in Part 2 doesn't come inside the aquarium, as the point was to rest survival entirely on Asa bowing to Fami's demands. Which backfires a different way, because the powers Fami needed her to use simply let her destroy their surroundings entirely.
Driven to Suicide: After realizing that it put itself into a lifetime of endlessly being cut apart by Denji, it eventually reveals its head to him and begs him to kill it just to make the pain stop.
Eldritch Location: Turns a hotel into one of these by making the eighth floor an endless loop.
Emotion Eater: All devils grow stronger the more they're feared, but the Eternity Devil's plan relied on making Special Division 4 paranoid over the possibility of being trapped forever. Over time it was able to feed off of their fear, growing its remote piece from a small head-like body to a grotesque blob of faces, teeth and tentacles able to block off the end of the hallway. The more they feared it, the more it grew, allowing it to get closer to them, creating an infinite loop of fear for it to feed off of.
Gravity Screw: Within its trapped space, it can either physically rotate the scenery or change the direction gravity pulls things, turning a hallway into a vertical shaft.
Heart Drive: Its heart is a blob of flesh, shaped like a lemniscate, and covered in multiple eyes and mouths. It's the only part it can't regenerate, but it can move other pieces of its flesh inside its trapped space from the outside.
Hidden Depths: Rather hilariously, the Eternity Devil seems to have a surprisingly good grasp of how the human economy works. It's infuriated when Asa's gambit to "buy" the aquarium works because, as it accurately points out to her, a million yen (about $8,000 US in today's money) is nowhere near enough money to purchase an entire aquarium and the land it occupies for development.
Eternity Devil: A measly million yen can't buy an aquarium, you moron!
Laser-Guided Karma: The Eternity Devil kills people by trapping them in an enclosed space until they go insane, starve to death, or are eaten by peripheral body parts. It's defeated by being forced to endure a lengthy, seemingly never-ending period of pain until it surrenders.
Miracle-Gro Monster: Feeding on fear makes its remote body swell in size enormously, going from a human head with hands and feet to blocking off a hallway in a few hours.
Never Recycle Your Schemes: Subverted. The Eternity Devil's reincarnation repeats the "trap the victims in an endless maze" scheme in Part 2. Despite having no memory of their last encounter, Eternity wises up and avoids defeat by refusing to reveal itself. Justified by the fact that it is working under Fami, who wants to create a situation that will force Asa making Denji a weapon by threat of starvation.
No Conservation of Energy: In its second appearance, its powers don't just make a fixed location loop unto itself, it creates a seemingly-endless train of physical duplicates thereof. This will make any food inside a renewable source for the Eternity Devil's victims, but only until it starts to rot.
There's drinking water in the fridge and more in the identical fridge in the identical lounge 20 meters down the hall.
This Cannot Be!: Reacts bewildered at his plan being ruined because Asa simply destroyed the aquarium after "buying it" with 1 million yen.
Eternity Devil: A measly 1 million yen can't buy an aquarium, you moron!
Time Loop Trap: All the clocks in the eighth floor are stopped at 8:18, giving reason that it's looped the eighth floor by also looping the time around it. Denji turns the trap against it by exploiting the infinite amount of time they have to fight to inflict infinite amounts of pain on the devil until it simply gives up on the loop out of desperation.
Unnaturally Looping Location: Turns the eighth floor of a hotel into an impossible loop; the Devil Hunters, no matter what manner of exit they find, always find themselves back on the floor entering from another side of the room.
Victory by Endurance: Its usual MO is to trap its targets in a pocket dimension, then wait for time and starvation to take care of the rest. When it foolishly reveals itself to Denji, he turns it against Eternity by just cutting it up over and over again and drinking the spilled blood to heal himself. After that, it's a matter if waiting to see if Denji gets too tired to continue or if Eternity breaks from the pain first.
Villain Decay: Eternity Devil's reincarnation in Part 2 is notably weaker compared its first appearance: It lacks its predecessor's Gravity Master status and its true form is simply a large humanoid figure rather than an endless mass of flesh and limbs. It's also defeated much easier compared to Part 1, where Denji had to essentially torture it for 3 days straight in order force it to reveal its heart. In Eternity Devil's encore, Yoru is able to kill it in a matter of minutes after its body is exposed via Asa turning the aquarium into the very spear used to slay it. This is Justified by the fact that this incarnation isn't receiving a power boost from the Gun Devil's fragments.
Voice of the Legion: It talks with many different mouths, possibly independently. The anime has its voice provided by several different voice actors whose lines are layered over each other.
Wake-Up Call Boss: Up until the Eternity Devil, most devils had been defeated in relatively short battles. The Eternity Devil's unique powers as well as its use of strategy and paranoia to turn the Devil Hunters against each other makes it a threat not so easily beaten. Denji has to fight/torture it with his chainsaws for three days straight before he finally breaks the devil's will and convinces it to commit suicide rather than go through anymore pain.
You Have GOT to Be Kidding Me!: The Eternity Devil is furious and utterly flabbergasted when Asa manages to "buy" the aquarium to destroy it and escape because, as it quite accurately points out, while it might work according to Asa's powers, in the real world 1 million yen (about $8,000 in US currency or €7,000 European) is nowhere near enough money to purchase an entire aquarium property and the land it's built on.

Ghost Devil

Voiced by: Hiroko Kiso

https://static.tvtropes.org/pmwiki/pub/images/b8d41a24705d47f79603a7ec11cd3905.png

The Devil representing humanity's fear of ghosts. In exchange for her right eye, it gave Himeno the power to use its hand.

Attack Its Weakpoint: While it can create as many hands as it needs without issue, it can't perform similar regeneration with its main body, even if its head remains intact.
Beast with a Human Face: Has the head of a Stringy-Haired Ghost Girl on top of a mound of flowers and arms.
Eyeless Face: Though its eye sockets are sewn together, Aki says it doesn't have any eyes at all. Closeups in the anime indeed show empty space behind the stitches.
Face–Heel Turn: Its contract with Himeno is converted over to Akane after it's initially defeated.
Foul Flower: Its midsection is covered in flowers, likely meant to represent the kind used to mark graves.
Helping Hands: Himeno's contract with it grants her usage of an third invisible hand from the Ghost Devil.
Horrifying the Horror: The Ghost Devil is actually terrified to fight Akane and her Snake Devil; it takes Himeno sacrificing her life to it to motivate it to actually fight them.
Mouth Stitched Shut: Both its mouth and its eyes are sewn shut.
Multi-Armed and Dangerous: When it's seen in full it's revealed that it has multiple hands that it works on and uses for attacks, such as with its fight with Aki.
Off with His Head!: Aki decapitates it after Akane summons it to fight him.
Perpetual Smiler: Its main head is constantly smiling.
Psychic Strangle: The Ghost Devil can give people who make contracts with it this power. When Power casually threatens to kill Kobeni to see how Himeno would stop her, Himeno uses the Ghost Devil's invisible, intangible hand to strangle her until Power drops her weapon.
Weaksauce Weakness: The Ghost Devil does not actually see people, instead it senses their fears. Aki manages to effortlessly kill it by suppressing his fear and sneaking through it.
You Are Who You Eat: Himeno's will appears to have persisted in the Ghost Devil to some extent after she sacrificed her body to it. Even after she disappears, the hand pulls Denji's cord and later hands Aki a cigarette to stay calm while fighting the Ghost Devil under Akane's control.

Curse Devil

Voiced by: Yuuko Ueda

https://static.tvtropes.org/pmwiki/pub/images/024_curse.png

The Curse Devil, shown attacking Samurai Sword

A contract Devil that's been used by both Public Safety and its enemies. It can kill anyone that's been struck with a special nail three times, but drains the user's lifespan.

Awesome, but Impractical: On top of the lifespan cost, it requires someone to stab their target three times with a spike to call on its power, though this is easier than with a regular weapon because of the Curse Devil's assistance.
Behind the Black: The anime version of its assists to Aki has it flick its finger into view, as if the Curse Devil was offscreen.
Cast from Lifespan: Aki's usage of the Curse Devil drastically reduces his lifespan to a mere two years.
Crucified Hero Shot: Its victims end up posed with their arms spread horizontally and their legs hanging down, which looks especially like crucifixion before it becomes visible and shows it's holding their arms in its hands.
Dem Bones: Appears to be a large skeleton with two horned heads and a very large rib cage it holds its victims in.
Frame Break: Its first usage has its finger flick into the panel to support Aki's attack.
Invisibility: Once summoned, the Curse Devil is invisible until it's grabbed and started killing its target.
One-Hit Kill: Instantly kills whoever its user is targeting when the conditions are met.
Playing Both Sides: Unlike Kon, it's contracted with Public Safety and against it (specifically by Tolka and his master).
Pragmatic Villainy: Probably because the cost of its primary ability is so high, the Curse Devil is fairly accommodating in leading people up to it. It apparently didn't charge Tolka's master anything to stick Denji twice before her apprentice did the third, nor for guiding Aki's weapon to land three blows in a fight.
Smash Cut: How it's power is shown in the anime; when it attacks Katana Man it comes up from behind him out of the darkness and crucifies him, which cuts immediately to Katana laying on the ground in a pool of his own blood.
Useless Useful Spell: Both in-series uses of the Curse Devil were on a Weapon Human, who was "killed" but in no way prevented from reviving by being fed blood. This was a straight example against Katana Man, whom Aki wasted years of his life against to only briefly delay. Tolka's use on Denji is a subversion, because while it doesn't kill him for good, all he needed to do was incapacitate him so he could be delivered to the Darkness Devil.

Snake Devil

The contracted Devil of Akane Sawatari.

Ambiguous Situation: Alongside the implications that Akane was secretly working for Makima, it gives the implication that Snake Devil executed her on Makima's behalf. Regardless, the Snake Devil is summoned along with the other devils Makima indirectly controls to attack the Gun Devil.
Attack of the 50-Foot Whatever: It's a big enough snake to chomp out the middle section of the Ghost Devil, itself a fairly large Devil. It's even bigger in the show, seemingly hundreds of feet long, which make its ability to instantly disappear seem even stranger. When Makima summons her army of devils against the Gun Devil, it's big enough to carry the other devils inside of its mouth.
Bodyguard Betrayal: After Sawatari has been captured by Kobeni, her own devil bites her head off and eats it.
Body of Bodies: The Snake Devil has what looks a beak comprised of severed human arms.
Comically Small Demand: The only price Sawatari paid for its loyalty was her fingernails, suggesting that either Snake prefers hunting other Devils to terrorizing humans (much like Fox) or it simply likes Sawatari for some reason. It's possible that the cheap price is balanced out by the fact that it apparently has the order to execute her upon capture.
Evil Counterpart: To the Fox Devil. Like Fox, Snake is a giant monster who gives its contractor Summon Magic to conjure it, has a very minimal cost, and attacks by Eating the Enemy. It fits, since Sawatari is herself an evil counterpart to Aki. Also like Fox, it ends up turning on its master, but where Fox simply bails and refuses to return, Snake is the one to kill Sawatari.
Foreshadowing: Showcases a hitherto unseen ability of Devils to regurgitate other Devils that they've devoured. This demonic quirk forms the central conflict of Part 2, where Yoru intends to coerce Pochita into spitting out the Nuclear Weapons Devil.
Power Parasite: Snake has the ability to steal contracts, allowing Sawatari to wield the contracting Devil's power at no additional cost to herself. We only see Ghost used in this manner before Sawatari dies and Snake disappears.
Snakes Are Sinister: An embodiment of human fear of snakes, its enormous size indicating there's plenty of fear for it to feed off.
Stealth Hi/Bye: It strikes out of thin air and disappears just as quickly; in the show, when Sawatari dismisses it, the Snake Devil instantly blips out of existence rather than gradually vanishing.
Villain: Exit, Stage Left: Snake peaces out at the end of the Katana Man arc and takes Sawatari's head with it.
You Have Outlived Your Usefulness: Kills Sawatari when she's detained and disappears from the story afterwards. While Makima speculates that it was so that Sawatari can't say anything about the Gun Devil, the later story revelations gives the implication that Snake killed Sawatari on Makima's behalf.

Future Devil

Voiced by: Hiroki (Japanese), Landon McDonald (English)

"♫Yeah, yeah... The future rules, the future rules...♫ The future rules! Say it with me, dude!"

The Devil representing humanity's fear of the future. It has the ability to perceive the fates of whatever it’s looking at and can share this power with its contractors, giving them the ability to see several seconds into the future. Despite this, the Future Devil still likes to watch particularly horrible futures play out with its own eyes, leading it to make a contract with Aki so it can personally watch him "die in the worst possible way!"

Adaptational Personality Change: While it entered the manga screaming its catchphrase ad nauseum, the animated adaptation makes it less manic and loud if still quirky; it doesn't even perform its memetic fist pump as it encourages Aki to say that the future rules.
All-Powerful Bystander: It embodies an incredibly widespread fear, but Future seems to have no interest in going on terrorizing humans like its kin and is instead content watching the horrible fates of its contractors.
Beware the Silly Ones: For a Devil, Future is a goofball. It sings and dances to amuse itself, and it's very loud and bombastic. It is, however, still a Devil; its main source of entertainment is the horrible fates of its contractors, and it's clever enough to use Aki to escape captivity, knowing that he would eventually die and free it from his eye.
Boxed Crook: Future is one of the Bureau's captive Devils, forming contracts with hunters from its jail cell.
Brain Monster: Downplayed. Future’s head is covered in lines that resemble an exposed brain.
Character Catchphrase: "Mirai! Saikou!", officially translated as "The Future! Rules!"
Comically Small Demand: Aki is warned Future asks a hefty price for a contract, giving the example of someone having their lifespan cut in half and another who lost both their eyes alongside their senses of taste and smell. However, Future itself reveals that it decides what price it will take depending on what it sees in the futures of its potential contractors. When it sees Aki's future, it's so amused by how he dies and what effect it has on his loved ones that the only price it demands is to reside in Aki's right eye, all so it can have a front-row seat to the whole thing.
Double Meaning:
- Future wants to witness Aki’s horrible death. When it finally happens, Future Devil elaborates that it meant the horrible effect being forced to kill Aki would have on Denji.
- His catchphrase is an expression of joy over the horrific fates he is privy to, of confidence that his visions are absolute, and of self-adulation as it praises the concept he represents.
Early-Bird Cameo: The Future Devil is briefly seen in the opening where it's dancing to the tune, long before it's introduced in the show proper.
Exact Words: It tells Aki he will die in the "worst possible way." It fails to mention that it meant for his friends — Aki himself dies quite peacefully.
Eyes Do Not Belong There: A massive one in an oneiric cavity in the middle of its chest, Future uses it to examine the future of potential contractors by having them shove their head inside it.
Faux Affably Evil: It's as malicious as any other Devil, but never stops acting like Fun Personified.
Fun Personified: It's energetic, cheerful, loves to dance, and seeks to entertain itself... with the horrible fates of its contractors. It is still a Devil, after all.
It Amused Me: Forms a contract with Aki essentially for free because it found his fated death hilarious and desires to witness it in person.
Kick the Dog: Displays just how whimsically malicious a Devil can be when setting up the terms of contracts, asking anything from just getting to see through a contractor's eye to having them fork over most of their senses or lifespan.
Malicious Misnaming: Refers to Denji as Chainsaw Boy.
Once More, with Clarity: Future tells Aki that it is giving him an essentially free contract because he wants to see his future, in where he will "die in the worst possible way." When Aki as the Gun Fiend is killed by Denji, causing the boy an insane amount of grief, the Future Devil reappears to clarify that Aki died in the worst possible way... for Denji.
Precognition: Grants Aki the ability to see a few seconds into the future, based on Future's own ability to foresee events of those it looks at.
Required Secondary Powers: Subverted. When Aki gains precognition from his contract with Future he admits that, while seeing a few seconds into the future is a major benefit, there's nothing to say that he can meaningfully act on the information he gleans. Whether it's from his mortal body being unable to react fast enough to capitalize on what he foresees or, in the case of the Ghost Devil getting him in a stranglehold, he can't act on it due to circumstances beyond his control, his precognition does have a few serious stays on its overall power. Future, being a Devil, presumably either doesn't have these limitations or has his own workarounds for them.
Sealed Inside a Person-Shaped Can: Future agrees to lend Aki its power in exchange for letting it leave its jail cell and reside within his eye… somehow. It's seemingly freed after Aki becomes the Gun Fiend and his eyes are replaced with a barrel, implying Future tricked him into helping it escape.
Self-Fulfilling Prophecy: Since the Future Devil wanted its vision of Aki to come true, it's able to make sure it happens by carefully selecting what details to feed to Aki. Once Aki's told Denji would kill both him and Power, Aki begs for Makima's help. This gives her full power over him, which she uses to force Denji to kill Aki.
Sir Swears-a-Lot: Amusingly, the anime adaptation gives it the biggest potty mouth of any Devil seen so far to match with its somewhat juvenile behavior. It approvingly tells Aki that his death will be "fucking horrible", and his brusque manner beforehand leads to it demanding that he "drop the shitty attitude for a start."
Small Role, Big Impact: The Future Devil is only even mentioned in one chapter of Part 2, but Yoshida's whole mission turns out to be based on it predicting dozens of disconnected people would all be dead by (and usually in) July 1999.
Vagina Dentata: The Future Devil's whole body is covered with shaggy hair and a vertical slit in its chest with an eyeball up top. It requires Aki to stick his head inside, and is pleased by the result.
Villains Never Lie: Future's premonition to Aki of how both he and Power would be killed by Denji, followed by "the devil that devils fear most" appearing both come true: Denji is forced to kill Aki after his possession by the Gun Devil, and Power gets killed by Makima when Denji opens the door for her. This results in Pochita taking over Denji's body after Makima breaks their contract, returning to his true form as the Chainsaw Devil, which all Devils fear as the "Hero of Hell." And even following her revival, Power dies for good by giving Denji all her blood in a Heroic Sacrifice.
Villains Out Shopping: It briefly appears in the first opening gleefully dancing along to the music.
What Happened to the Mouse?: Future seemingly escapes completely from its imprisonment and the story itself after it witnesses Aki's horrible death like it wanted. No clarification about where Future went afterwards is made in Part 1. It's mentioned in Part 2 that Public Safety used the Future Devil in an experiment, but that may have been conducted before Aki's contract.
When Trees Attack: It resembles a towering humanoid tree covered in fur.
You Can't Fight Fate: The Future Devil's visions appear absolute—at least when it wants them to happen. Them being useful for Combat Clairvoyance implies some kind of Multiple-Choice Future, but one the Future Devil manipulates to its own wicked ends.

Spider Devil

Angel Devil

See Angel's folder here

Typhoon Devil

https://static.tvtropes.org/pmwiki/pub/images/typhoon_color.jpg

A devil that embodies fear of typhoons.

Attack Of The 50 Ft Whatever: Manifests as a giant typhoon of intestines with the head of a baby.
Body Horror: Its manifested form is a giant baby-like creature with exposed brain and guts swirling around it.
Disc-One Final Boss: Along with its Serial Killer partner, it's built up as the major threat of the Bomb Devil arc. But in spite of its power and incomprehensibly horrific true form, it's quickly talked into submission by Bomb Woman and becomes her lackey.
Horrifying the Horror: Its true form is that of a tornado of intestines and it can manipulate the weather. In spite of all that and even having power over her Logical Weakness, it's scared shitless of Bomb Woman and very quickly kowtows to her when she recognizes it. And of course it, like other Devils that faced Denji before it, ends up screaming at him to stay away from it.
Small Role, Big Impact: Whilst he is small potatoes in relevance in the arc he appears in, his attack is incredibly important in Part 2, as it caused the death of Asa's entire family, leading to her depression as well as her distaste for all devils, Chainsaw Man included.
Weather Manipulation: A weather-related devil, with powers related to heavy wind and torrential rain.
You Don't Look Like You: The Typhoon Devil appears in a flashback in Part 2, but the human part looks like an old man instead of a baby, including very prominent nose hair. It may or may not be a different incarnation.

Octopus Devil

https://static.tvtropes.org/pmwiki/pub/images/0061_008_2.png

The Devil representing the fear of octopuses, exclusively shown contracted to Yoshida.

Combat Tentacles: Fights using tentacles.
The Ghost: In a sense; while its tentacles have been used a bunch onscreen, the main body has never been present.
Killer Rabbit: Octopuses aren't exactly known for being fearsome creatures, but the Octopus Devil appears to be rather powerful.
Mars Needs Women: If Yoshida's popularity poll description can be taken as canon fact ("women, men and octopuses are captivated by him"), it may point to the Octopus Devil having an attraction to him.
Mundane Utility: While one of its tentacles fights an army of dolls, it allows Yoshida and Kishibe to sit down on another as a makeshift seat.
Superpower Lottery: Its tentacles are strong, easily battering and ripping apart things. On top of that, it can also shoot ink and Part 2 shows that it can snatch people and bring them elsewhere as a teleportation method. Notably, Yoshida seems to freely use all this, implying that the cost is cheap - if there even is one for him.
The Worf Effect: To demonstrate how strong Yoru got from her upgrade, she effortlessly cuts her way out of being constricted by a tentacle when Octoous has effortlessly grappled everything else.

Hell Devil

The Devil representing the fear of Hell, which in the present has become synonymous with the realm Devilkind hails from. As a result, it is a very unique existence among Devils that does not adhere to the normal rules of reality, and can readily move itself and others through the barrier between Hell and Earth at will.

All-Powerful Bystander: The Hell Devil can seemingly act in any place, on any being, transporting them between the realms of Earth and Hell. But it remains a purely neutral figure, only acting when carrying out a very specific Contract.
Eldritch Abomination: It is not beholden to the normal rules about devils needing to die to go between Earth and Hell, instead being able to freely appear in either world. Further, its powers manifest as strange Breaking the Fourth Wall imagery, like breaking through comic frames, or manifesting as a hand the size of a reader's to reach into the comic panel and pull its targets out.
Extra Digits: When shown as just a hand taking people to hell, it has six fingers. Ironically, the full-body form it takes later has Four-Fingered Hands.
Frame Break: It consistently breaks the frame, acting from outside of the pages to influence the universe.
Hellgate: It serves as one, allowing movement between dimensions. It is not The Jailer, however, and isn't obligated to stop anyone in Hell from leaving it if they possess the means.
Human Sacrifice: The two times a contract with it is made in Part 1, its price is multiple human lives.
Our Centaurs Are Different: When summoned to fight against Makima, it takes on the appearance of a flaming, eyeless centaur made out of the intestines of the people who summoned it.
Uncertain Doom: Its summoned formed is reduced to a head, fed blood to revive while being told "Die after you do your job", and then manages to send its target to hell. If it survives afterward isn't clear. The destroyed form it took was also different than the one shown previously (i.e. different hands with different numbers of fingers), suggesting its opponent was just Fighting a Shadow.
The Worf Effect: The devil who effortlessly sent everyone to Hell is dispatched in one hit to clearly demonstrate just why Pochita/Chainsaw Man is The Dreaded of Hell.

Darkness Devil

https://static.tvtropes.org/pmwiki/pub/images/darkness_94.png

The Devil embodying the fear of the dark. As one of the most basic and primordial of all fears, it is phenomenally powerful.

Prior to the International Assassins Arc, Darkness formed a Contract with the assassin "Santa Claus"; in exchange for bringing Chainsaw Man to Hell, she would be allowed to eat a piece of its flesh to become powerful enough to slay Makima.

Ancient Evil: Devils are typically caught in an endless cycle of death and rebirth that transports them between Earth and Hell. But thanks to Darkness's incredible strength, it has never died, meaning it's been around as long as humanity has while maintaining the same identity and memories.
A God Am I: The moment isn’t dwelt upon, but the bisected astronauts Darkness conjures to taunt Public Safety have seemingly been arranged to look like they’re praying to It.
Attack! Attack! Attack!: Most Devils in the series display at least some form of strategy and reasoning, including retreating when necessary and are capable of human speech. The Darkness Devil is simply phenomenally vicious and never displays even a hint of (recognizable) motivation or personality other than taunting its prey with a gruesome corridor of dead astronauts and instantly attacking anything that enters its domain that it even remotely perceives as a threat.
Badass Boast: Darkness actually manages to pull off a non-verbal one with the aisle of bisected praying astronauts that heralds its arrival. These people likely perished from drifting off into the void of space and, disturbingly, they all clearly met the exact same fate. No matter how advanced humanity gets and attempts to conquer all forms of darkness, the fear of it will never go away and its Devil will never stop being the horrifically powerful entity it is because of it.
Black Speech: The one time Darkness "speaks", it produces a black speech bubble containing a mangled clump of pen strokes that leaves Violence severely mutilated.
Blasphemous Boast: A rare non-verbal one in the first panel it actually appears: it introduces itself through a corridor of bisected astronaut corpses arranged so it looks like they're praying. Since space is the darkest environment imaginable, the implication from having the astronaut corpses present seems to be a message that either the astronauts' prayers for salvation from the Darkness Devil went unanswered, or it's the one they're praying to.
Body of Bodies: A horrifying creature composed of multiple corpses, melded together into a vaguely avian shape that is difficult to grasp.
Breaking the Fourth Wall: In a similar manner to the Hell Devil, some parts of its existence seem to interact with the nature of the manga itself, adding to its eldritch and incomprehensible nature. When it first appears, it preforms Literal Disarming on most of the assembled parties in front of it in a double-spread, with the severed limbs drawn in mid-air alongside its own body to outline the word 'Makima' in english, implying this was the Darkness Devil's way of calling out to her.
Brown Note: Among its numerous deadly superpowers is the ability to emit syllables of Black Speech which shred the target into pieces just from hearing it, as happened to the noble, doomed Violence Fiend.
Characters Dropping Like Flies: Its appearance really kicks the Anyone Can Die effect into overdrive, and in only two chapters it casually kills no less than seven named characters (Beam, the Violence Devil, Kukasabe, Tamaki, Tolka, Long, and Pingtsi) with absolutely zero effort, not to mention permanently crippling Aki and the Angel Devil.
Combo Platter Powers: Darkness displays numerous completely disconnected abilities during its assault on Public Safety. Including summoning a giant katana to crushing and twisting bodies with Its mind to instantly teleporting behind the Devil Hunters to somehow causing Kusukabe’s contracted Stone Devil to appear in its hand before crushing it and Kusakabe to dust.
Curb-Stomp Battle: Darkness effortlessly dispatches everyone, removing limbs and killing those foolish enough to oppose it. The only person to give it trouble is Makima, herself a Devil of immense power, and while she survives the encounter with far lesser injuries than her coworkers, even she’s obviously outmatched.
Darkness Equals Death: Natch, Darkness' arrival is heralded by Hell's scenery melting away into a completely lightless void.
Deadly Gaze: It almost kills the Angel just by staring at him for a few seconds, causing him to start bleeding severely from the eyes and collapse. It appears to be an ability shared by all powerful Devils since Makima also used it against the yakuza.
Defeating the Undefeatable: Darkness is one of the only Devils in the series that stand a good chance to permanently kill Makima. When she shows up in Hell to rescue her employees, she lands one good hit on it but is still incredibly outmatched, and given how its Devil powers and hers seem to work (Makima has the ability to transfer any damage inflicted on her to any other citizen of Japan, but it's not clear if she can still access their lives to protect her own while she's in Hell. The Darkness Devil appears to have the vaguely defined power, to the extent we can understand it, to do whatever the fuck it wants to do to anyone who's encompassed by its realm of shadow), it's entirely possible that it would be able to kill Makima for good.
Domain Holder: The simplest summation of the Darkness Devil's powers is that it can do anything it wants in the darkened area surrounding it. Distance alone probably won't save you, as the Darkness Devil found and reached Denji's party moments after they arrived. The only implied limitation is that it cannot (or at least doesn't want to) leave Hell.
The Dreaded: Both Public Safety and Quanxi’s Fiends are completely paralyzed with dread when they sense Darkness looking at them, and a handful of them are too terrified to even to do anything once it comes. Even Makima is cautious enough around it that she only confronts Darkness after it kidnaps Denji and forces her hand.
Eldritch Abomination: Darkness is one of the Primal Fears; an ancient, primordial creature whose power is drawn from one of the most basic and universal of all phobias and consequently wields strength infinitely greater than almost every other Devil. It exists on such a higher plane that humans, Fiends and even powerful Devils can only perceive its movements as surreal, unrelated imagery like a frog croaking.
Enemy Rising Behind: The first time it's actually seen clearly is when it instantly teleports behind the Public Safety agents in its domain, followed moments afterwards by instantaneously removing all of their arms cleanly.
Establishing Character Moment: The very first thing we see of it is it looming ominously at the end of a gruesome corridor of 18 dead astronauts, cut in half and praying to their own bisected lower halves. It's the first indicator that they are all facing something that is not only actively malevolent but dangerously intelligent, leaving the astronauts out to taunt the humans who enter its domain: astronauts symbolize the pinnacle of mankind's scientific, intellectual, humanitarian, educational, and athletic achievement, and by marking its territory with their mutilated, humiliated corpses, the Darkness Devil reminds everyone that humans will never be safe from the primal fear it represents.
Flying Weapon: It kills the Violence Fiend and nearly does the same to Makima using a massive, ornate katana with four bells tied with string to the crossguard, levitating it at will instead of wielding it.
Foreshadowing:
- That even a creature as horrifyingly powerful as Darkness desires to claim Chainsaw Man’s heart is one of the first hints given to the true power of the Chainsaw Devil, quite possibly the only thing in existence that could actually kill a Primal Fear Devil.
- Similarly, the fact Darkness takes the opportunity to challenge Makima to a fight, implying it considers her a threat for some reason, is a clue that Makima herself is a Devil of phenomenal power.
- When Denji takes a flying leap to punch it in the face with his chainsaw arm, the Darkness Devil appears to be leaning back and away from his blow, as if to actually dodge an attack for the first and only time during its one-sided "fight" with Public Safety. Additionally, the ghostly faces that surround it in that panel all have shocked expressions. This is another hint at how insanely powerful Chainsaw Man's true power is, if even the Darkness Devil won't risk getting hit by it.
Greater-Scope Villain: Of the International Assassins Arc: Darkness only shows up for three chapters and gives up the chase after Makima rescues Division 4 from Its clutches, but its contract with Doll Woman is what lead to her going after Denji in the first place and is what makes her powerful enough to pose a threat to him and Quanxi during the climax.
Half the Man He Used to Be: The arrival of Darkness is heralded by the appearance of astronauts, all lined up neatly with their upper half on one side and their legs on the other, forming an aisle.
Hero Killer: Casually rips Beam, the Violence Devil, Tamaki, Kusakabe, Tolka, and two of Quanxi's girls to shreds without even lifting a finger.
Horrifying the Horror: Devils are what humanity fears. Darkness is what other devils fear, its mere presence causing the Devils and Fiends in the group to cower and beg permission to kill themselves before it notices them.
Killing Intent: Its hostility is so powerful that Devils and Fiends can tell if Darkness is looking at them even from far away.
Knight of Cerebus: In a cast of characters that all have at one point partaken in comedic moments, Darkness is one of the very few to be played completely straight without a hint of silliness or quirkiness to it. Its battle with Public Safety is one of the most genuinely unsettling scenes in Part 1, and leaves Power and Kobeni so traumatised that the latter quits Public Safety while the former can’t go anywhere without Denji. While it's admittedly not wholly responsible for this change, the tone of the series itself gets a lot darker after its appearance as almost all the comedy is entirely drained away as the survivors of its massacre are left to wrestle with what little they still have left.
Know When to Fold 'Em: It's conspicuously absent during Pochita's rampage through Hell as a revived Chainsaw Man, implying that the Darkness Devil won't fight opponents that are too dangerous if it can help it.
Literal Disarming: It has the ability to instantaneously sever the arms of any target without damaging their clothes, and judging from Angel’s inability to regrow his lost limbs, the effect ignores the healing ability all Devils share. Strangely, it appears there’s a seemingly-random chance for the victim to later stick them back on as good as new.
Magical Gesture: Points the index finger of one of its multiple arms at people several times when it uses its powers on them.
Meaningful Name: As its name suggests, the Darkness Devil is the embodiment of mankind's fear of the dark. Or rather, more accurately as its abilities might suggest, what humanity might find in the dark.
Mind over Matter: If not an outright Reality Warper, the Darkness Devil has incredibly powerful telekinesis, most often used used to Clean Cut its opponents into pieces.
Monkey Morality Pose: The four corpse heads that make up its abdomen are all missing a facial feature corresponding to one of the Monkeys: The first has sewn-shut eyes, the second is missing any ears, the third has a sewn-shut mouth, and the fourth is completely featureless and connected to the two torsos it uses as legs.
No-Nonsense Nemesis: The second it realises Denji (or more specifically, a weakened Pochita) is in Hell, it teleports straight to his location and tries to land the killing blow as soon as possible.
Non-Human Head: A very bizarre example. While the majority of its body is comprised of human corpses; Darkness's head is instead a metallic, skull-like object reminiscent of a pterodactyl fossil. It presumably symbolises how long the Devil’s been around.
Nothing Is Scarier:
- Interestingly, in addition to how it's one of the most terrifying examples of this trope being done effectively in manga history, it appears to have this coupled with the Rule of Scary as an actual power. The way it responds to people who enter its domain and the things it does to them are so seemingly unrelated and are so bizarrely abstract that it seems to represent less the fear of shadows themselves than it does the fear of horrible things lurking in the dark that you can't see coming or prepare yourself for, and of being completely helpless and at the mercy of something frighteningly old and horrifically malevolent that you can't hope to even understand, let alone fight.
- Its first appearance in Chapter 64 is also a perfect execution of this trope to the scariest possible extent. Right in the middle of one of the most chaotic arcs in the whole series, with more than a dozen new characters each with their own agendas being introduced, betraying, and killing each other, the action is brought to a screeching halt when most of the main characters are abruptly teleported to a beautifully tranquil grassy field with no signs of other Devils anywhere. Suddenly all the Fiends present abruptly start panicking, collapsing in pain or begging to kill themselves, while the Angel Devil observes in horror that they're Being Watched, a door opens in the sky, and a blob of pure shadow falls to the ground like a malevolent raindrop and instantly blots out all light. Only then do we get a glimpse of its true form: a shadowy, indistinct and utterly inhumanoid mass barely visible as an ominous silhouette looming at the end of a corridor of dead astronauts praying to their own severed lower halves.
Not Worth Killing: It makes its entrance by cutting everyone's arms off to disable them, but otherwise only actively hunts down Denji. Everyone else it either kills in retaliation or seemingly by accident, and it pays no attention to Kobeni running off to hide. Giving the spectacle of its entrance, it may enjoy basking in their fear.
Outside-Context Problem: So powerful, so ancient and so inhuman as to effectively be operating on an unknowable, completely different set of rules to everyone and everything else seen so far. It seems to be wary of the Chainsaw Devil, but even that's up to debate because its behavior is so strange. Anything and anyone else might as well be termite in a hurricane.
Painting the Medium: Many of the Darkness Devil's attacks are shown through bizarre and seemingly random imagery like pointing fingers or croaking frogs that intersect with the layout of the panels, as if the very boundaries of the manga format itself cannot properly contain the true nature of its power.
Primal Fear: The personification of the fear of the dark. Though Darkness appears to embody less the fear of darkness itself and more the inability to understand what's going on around you being in the dark brings: Its attacks are all so bizarre and lacking in any connecting theme that there's no way to guess what It's going to pull out next. Its bizarre form melds with the shadows in such a way that it's hard to describe what you're even looking at at first glance, and Its total lack of speech gives it an unknowable, alien presence.
Rule of Scary: Interestingly, it appears to operate on this principle as an actual superpower. Most of the abilities it attacks Public Safety with (being stabbed by flying swords, being cut to pieces instantly, having your bones broken and your body twisted broken in hideous ways, hearing something so horrible it rips chunks out of your flesh, having something horrible suddenly appear behind you and remove your limbs) seemingly have little to do with one another other than they're all scary, extremely grotesque, and hard to process fully. It seems that being the Darkness Devil has less to do with control over Darkness itself and more about the fear of horrible things happening to you in the dark for no reason and that you can't see coming until it's too late.
Silent Antagonist: Never speaks a single word even while it's mutilating and eviscerating everyone in Division 4 simultaneously. The only time it makes a sound is when it utters an utterly incomprehensible syllable that looks like multiple different speech-characters layered on top of one another and which instantly blows dozens of holes in the Violence Fiend's body.
Story-Breaker Power: The most powerful devil encountered during Part 1, with Division 4 having to call on Makima just to survive the fight with it. If it wasn’t seemingly unable or uninterested in leaving Hell and didn’t give up the chase after she retrieved them, the series probably would have ended then and there.
Superpower Lottery: Most Devils and Fiends have one or two primary theme-appropriate abilities ontop of the blood-fuelled Healing Factor all members of their kind share. But it seems the vagueness of the fear Darkness represents means there’s no limit to what it can make happen as long as it falls under the broad umbrella of “scary and bizarre”: including teleportation, trapping people in a void of pure darkness, instantly cutting enemies into pieces without even touching them, instantly healing from any damage, telekinesis, killing people by looking at them, forcing enemies' contracted Devils to appear (and crushing them instantly), and Spontaneous Weapon Creation.
Super-Empowering: Darkness feeds Doll Woman a piece of its flesh as reward for delivering Chainsaw Man, enhancing her existing powers and rendering her invincible while not near any bright lights.
The Unintelligible: The Darkness Devil is a Silent Antagonist for the most part, speaking not a word as it brutally eviscerates Public Safety and Quanxi's Fiends. The one time it does speak, it utters incomprehensible gibberish.
Words Can Break My Bones: The only time the Darkness Devil speaks, it's an utterly unintelligible mess of symbols that turns the Violence Fiend into Swiss cheese.
World's Strongest Man: Aside from the Chainsaw Man, Darkness is the most powerful Devil in Part 1, with known heavyweights Quanxi, Denji, Violence, and even Makima failing to do more than inconvenience it. Part 2 would later introduce the Falling Devil, a fellow Primal Fear Devil who is shown to also be extremely powerful, implying Primal Fears are far and above the strongest Devils in existence, and then it's officially toppled from this position with the Death Devil.
You Cannot Grasp the True Form: Most of Darkness's attacks are interspersed with pieces of nonsensical unrelated imagery like croaking frogs, praying bisected astronauts, dozens of pointing fingers, or bursts of Black Speech, before abruptly cutting back to its victims having been violently torn apart. It's not clear whether it causes the effect intentionally or if its true nature is just so incomprehensible that this strange imagery is the only way the mind can safely perceive it.

Gun Devil

The Devil that embodies the fear of firearms and the current highest priority target of Public Safety. Gun first appeared during a worldwide spike in gun violence 13 years ago where it killed 1.2 million people in under 5 minutes, leading to a massive increase in the fear of Devils in general.

Achilles' Heel: Each of its shots is theoretically an Instant Death Bullet that goes in a target's head or its heart, killing them. However, it only gets one guaranteed bullet per target, so someone with a prodigious Healing Factor can theoretically get back up to keep challenging it.
Allegorical Character: Gun's climatic appearance during its titular arc is extremely reminiscent of the WW2 bombings of Japan. It's used as a WMD by an unscrupulous American government to quell a Japanese threat that inflicts an absolutely horrifying number of civilian casualties. All while noticeably failing to even leave a scratch on the intended target: Makima, the Control Devil. The obvious message being that no weapon in the world is anywhere near as dangerous as an authority willing to unleash it heedless of those caught in the crossfire.
Almighty Idiot: For all its incredible power, Gun appears to be much less sapient than the vast majority of Devils. It can form and carry out Contracts and recognise when its life is in danger, but it never once speaks and seems incapable of any greater strategy beyond "shoot at it". This may relate to it being divided up into pieces. It's implied this lack of personality left enough room for something left of Aki’s mind to survive after Makima forcibly merged them into the Gun Fiend.
Always Accurate Attack: When attacking automatically, its bullets strike the head or heart of individuals that fit its target criteria.
Always a Bigger Fish: The first time anyone saw the Gun Devil after its initial attack, someone had already rendered it unconscious, letting devils and human governments carve it into many pieces. When the US send their 20% after Makima, she easily overwhelms it with her army of brainwashed devils and contractors.
Animal Motifs: The fifth ED of the animated adaptation depicts it as an equine Animalistic Abomination made of guns and human hands, calling to mind the shape of its "snout" (gun muzzle) and foreshadowing how it and Aki will eventually "ride" one another as the Gun Fiend.
Bloodbath Villain Origin: The Gun Devil was born about a decade prior to the story, in the wake of a rising fear of gun violence. Cue a death toll of several million in only a few minutes.
Bloodless Carnage: While its head and limbs are comprised of enormous firearms that can tear the landscape to pieces, its auto-targeting attacks kill people with regular caliber ammunition, resulting in a disturbing lack of gruesomeness and intact corpses.
Body of Bodies: Its chest cavity is stuffed with bald human heads, whose faces are writhing in agony.
Boom, Headshot!: One of the Gun Devil abilities fires a bullet through the heads of every living adult male within 1000 meters and every child under the age of twelve within 1500 meters.
Cast from Money: Uniquely, it's described as exchanging the guns and ammo it creates for money, much like a human Arms Dealer. This is one of the hints the Gun Devil wasn't really involved with the deal.
Cast from Lifespan: The Gun Devil is summoned by the President of the United States for the cost of one year from the lifespans of every United States citizen.
Combat Pragmatist: It shrewdly stays far away from Makima as it fires upon her, beyond the range of any previously seen Devil contract or other ability so it can kill her with no danger to itself. It turns out that it wasn't quite as safe a distance as it looked.
Death by Looking Up: At the end of its fight with Makima, it looks up just in time to notice that she'd summoned a huge, indistinct devil (or mass of devils) directly above it.
Disc-One Final Boss: For the three-quarters of the series, as it's built up as the ultimate threat that humanity and Public Safety are looking to defeat after a devastating attack across the world that made it the most feared Devil thus far. However, it's revealed that it's already been defeated and once it physically appears, it's abundantly clear that whatever villainy it represents is nothing compared to the true Big Bad Makima.
The Dreaded: Said to be the most dangerous Devil, capable of leveling cities in seconds.
Eagleland: Rather appropriately matches the trigger-happy Type B, as it's the personification of humanity's fear of guns and is called upon by the United States President to act on America's behalf. Its name in Japanese (Jū no Akuma) is even a near homophone for "Freedom Devil (Jiyū no Akuma)".
Early-Bird Cameo: The anime's first opening has an Extreme Closeup of its ammo belt dangling over a mountain.
Early-Installment Weirdness: Its first onscreen victims are shredded to pieces by gunfire. Everyone else it hits gets Pretty Little Headshots.
Fantastic Nuke: Its titular arc reveals that after it was defeated and left unconscious by an unknown assailant, Gun’s body was split up and the pieces claimed by various world powers, the threat of one of them resuscitating the Devil through a Contract and having it go on another rampage in their enemies’ territory keeping them all locked in a Cold War. Its status as a nuke replacement is made evident when it's later revealed that nuclear weapons have been erased in the world, with Gun Devil pieces taking their place as deterrents.
Fog Feet: It has no legs, just ammo belts hanging off the bottom of its torso.
Foreshadowing: The yakuza who made a deal with the Gun Devil were noted to sacrifice money rather than any body parts, something the yakuza boss notes is strangely human in behavior. If you're thinking it's just a straightforward transaction of money for goods rather than a contract, you're be correct. The Gun Devil has been inactive for a long time; in reality, it's human governments selling guns in black markets despite public restrictions.
From Nobody to Nightmare: The whole point of the Gun Devil is that it isn't special - it was just lucky enough to be born with the right concept in the right place at the right time, and that was enough to let it ride a feedback loop to godlike power. Much of the manga's plot is based around various factions trying to make sure that various devils don't (or do) get exposed to the same runaway power escalation that made the Gun Devil what it is today.
Fusion Dance: Its confrontation with Makima ends with it merging with Aki, showing back up at his home in a mutated state.
Generic Doomsday Villain: Has no real personality to speak of and appears to have no desire but to lay waste to everything in sight. This is actually invoked by Makima, painting it as a huge threat that Denji has to fight and defeat to get what it wants with no further discussion on its motivations so she can more easily manipulate him.
Godzilla Threshold: The Gun Devil is finally summoned by the President of the United States, as a last ditch effort to save the world from Makima — the Control Devil.
Gone Horribly Wrong: Seeing as how a majority of Devils aren't Immune to Bullets, there was a spike in gun production for the purposes of Devil hunting and civilian defense. Regulation could not keep up with the influx of firearms, allowing for a massive surge in gun-related crimes which wound up creating the Gun Devil. Even worse, its humongous international kill count increased the fear in Devils overall, making every single one of them stronger.
Imperial Stormtrooper Marksmanship Academy: Aims all of its guns at Makima from 500 kilometers away. Only one of its bullets hit.
Knight of Cerebus: Its appearance and possession of Aki instigates some of the series' biggest Wham Episodes and makes the plot take a turn for the worst.
Long-Range Fighter: It can engage in combat from kilometers away.
MacGuffin Super-Person: Pieces of the Gun Devil appear to increase the power of other devils. In reality, the Gun Devil was divided up years ago. Governments across the world are looking to stockpile portions of its body, to solidify their influence on the world stage.
More Dakka: It can fire seemingly billions of bullets, vast enough in quantity to level a city and fast enough that the attack appears near-instantaneous.
Multiple Head Case: A very strange version: it has an Eyeless Face, but its chin has eye holes, nose holes and teeth suggesting a second, more humanlike skull, along with the hundreds of heads that are also visible (presumably from its victims).
Normal Fish in a Tiny Pond: It's the devil who receives the most fear for its physical presence on Earth, but there are Devils far more powerful than the Gun Devil hiding in the shadows, like those that embody the Primal Fears, or the Four Horsemen.
Oh, Crap!: The only indication of intelligence and self-awareness Gun ever displays is when it looks up to see an army of Makima's enslaved Devils about to fall on its head.
Orcus on His Throne: Gun has not been seen in years, since the worldwide event. Instead, it has gathered followers to pursue Chainsaw and carry out well-organized attacks. Subverted when it turns out the Gun Devil is merely a mindless superweapon, and Makima is the one who's really manipulating everything.
Person of Mass Destruction: Gun is a being powerful enough to have killed millions, all over the world, in a matter of seconds.
Red Herring: The Gun Devil has been more or less under control since shortly after it showed up. It turns out that Makima is the far more dangerous threat.
Reports of My Death Were Greatly Exaggerated: Since the public isn't aware the Gun Devil had been divided into pieces, they think the 20% killed with the Gun Fiend was the whole thing. Theoretically, this should make the existing pieces of the Gun Devil much weaker.
The Scapegoat: It has not been supplying people with firearms to bypass international treaties. Human governments have been doing so while using the Gun Devil as cover.
Sealed Evil in a Six Pack: About a third of the Gun Devil's mass has been split off and consumed by various other devils to gain more power. The rest had been divided up between human governments, the overwhelmingly majority by the Soviet Union, US, and China. Most governments are looking to obtain more pieces for themselves to increase their global influence. Late in the manga, the United States' share is destroyed when it becomes the Gun Fiend and is slain, though Makima was able to use its powers thanks to a posthumous contract with its host.
Skull for a Head: Its head is very skeletal, with its jaw attached by exposed muscles, though quite different from a human skull—though its chin looks more like another human skull.
Spontaneous Weapon Creation: In a Boring, but Practical manner; most contracts with the Gun Devil simply have it create (completely mundane) firearms, letting its Contractors to bypass the worldwide gun control laws put in place after its cataclysmic first appearance. This turns out to just be a means of Plausible Deniability for state-sponsored acts of violence.
Stealth Pun: One of its abilities doesn't target anyone born in the months of April, July or October. The names of the first two in Japanese contain homonyms for "death" (死, shi: April is shigatsu, "4th month," and July is shichigatsu, "7th month.") Meanwhile, the last one contains a homonym for "gun" (銃, jū: October is jūgatsu, "10th month.")
Super-Speed: Gun can travel at unbelievable speeds; it was able to circle the globe in just under five minutes right after first manifesting and attacked so quickly it appeared completely invisible to the victims. Though interestingly, the Devil seems to lack the Required Secondary Power of being durable enough to move at such velocity safely: around a third of Gun's flesh was seared off its body in the process.
Unseen No More: Gun spends most of the manga unseen, though its presence is a constant in the series through its minions and fragments being collected. It finally appears in Chapter 75.
Walking Armory: It has a huge amount of guns melded to its body, mostly assault rifles and machine guns (albeit scaled up to the size of houses). The mass that makes up its arms actually fire, but the ones on its back and in its head appear to just be decorative.
Weaponized Headgear: The Gun Devil has a Hand Cannon going through its head, although it's never shown firing.
The Worf Effect: Set up as the most dangerous devil in the entire world, only to be defeated in a few panels to show how infinitely more dangerous Makima is. Although…
Worf Had the Flu: The manifestation of Gun summoned by America in a last-ditch effort to kill Makima was formed from only 20% of the Devil’s actual mass, a condition implied to have significantly dampened its power.
Would Hurt a Child: Its first action upon being summoned is to kill every child under the age of 12 within a 1500 meter radius.

Debuted in Part 2 (Unmarked Spoilers for Part 1)

Chicken Devil

Bucky / Chicken Devil (JP: Kokepi / Niwatori no Akuma)

https://static.tvtropes.org/pmwiki/pub/images/bucky_96.jpg

The Devil representing the fear of chickens, which as you might expect isn't very powerful.

Absurd Phobia: Bucky is born from an irrational fear of chickens. While real-world chickens can be aggressive and violent, they're too small to actually hurt humans, and thus Bucky is a very weak Devil. So weak, in fact, that it dies gruesomely from a teenaged girl falling on it.
Advertised Extra: Teaser images for Part 2 frequently featured him alongside Asa rather than Yoru, but his presence and purpose in the story is largely metaphorical.
Ambiguous Gender: Not referred to as any specific gender; in English the students at first call Bucky "it", but after getting familiar always call it by name. Chicken meals like Bucky resembles are almost always made from hens, but since it is a Devil it may not have any biological sex.
Arc Symbol: Bucky dies in the first pages of Part 2, yet dead chickens repeatedly show up as a symbol for the guilt Asa feels from the increasing number of bodies piling up around her.
Class Pet: It's kept as a pet by Asa's class, though eventually considered more of a fellow student.
Death by Falling Over: Tragically inverted; Bucky dies from someone else tripping onto it.
Decoy Protagonist: Prior to the beginning of Part 2, Bucky was featured prominently in promotional art with Asa, implying that it'd play a similar role to Pochita. That idea goes kaput along with Bucky itself in the very first chapter of Part 2, and instead Asa partners with Yoru the War Devil.
Dub Name Change: Called "Kokepī (コケピー)" in Japanese and French, "Bucky" in English, "Quiquiriquin" in Spanish, and "Cocopi" in Portuguese.
Human Outside, Alien Inside: Bizarrely inverted; outside it looks like a cooked chicken, but its spilled intestines look much more like a human's.
Kill the Cutie: A friendly, harmless devil that ends up getting crushed to death when Asa trips and falls on it.
A Lizard Named "Liz": Its names in every language is a pun on onomatopoeia or words for sounds hens and roosters make. In Japanese, "koke koke" in the sound of clucking. "Bucky" plays on "buck-aw", and is also a joke on fried chicken coming in "buckets".
Made of Plasticine: Asa falling on top of Bucky isn't just fatal, it squeezes its guts out.
Pungeon Master: Has a habit of constantly making jokes based on eggs and other things related to chickens.
Small Role, Big Impact: Even though Bucky is killed in the very same chapter in which they're introduced, Bucky's influence lets Asa grow a little as a person, while their death directly leads to her meeting the War Devil. A good while later, Asa even has nightmares where she has to run across ground covered in dead chickens, as if Bucky became an icon of her trauma at seeing others suffer.
Token Heroic Orc: Bucky is a completely friendly Devil, to the point that he builds a sincere bond with Asa's classmates. This reminds readers that relations with Devils can be amicable while contrasting the pointedly vicious and unfriendly Yoru who becomes the protagonist's main companion.
What Measure Is A Nonhuman: Subverted; Mr. Tanaka introduced Bucky saying it'd be killed as part of the lesson, but the actual point was for the class to get attached and refuse.
You Are Not Alone: Asa is shocked to learn that Bucky knew her name despite never making an effort to interact with them, and it motivates her to finally come out of her shell and try to make friends with her class. Then she trips.

Justice Devil (Unmarked Spoilers)

See the Chainsaw Man Church's page, but be warned that all spoilers are unmarked

Cockroach Devil

The Devil embodying the fear of cockroaches. It appears, crushing the Bat Devil, and is soon killed by Denji.

Creepy Cockroach: It may be humanoid and gigantic but it’s a cockroach.
Curb Stomp Cushion: Denji is way too strong to do anything other than completely overpower the Cockroach Devil, but it does get a few licks in before he takes it out.
Fake Ultimate Mook: While it's one of the largest and most physically mighty Devils in the series, at the start of Part 2 Denji is so freaking strong that it's nothing to him.
Irony: A Devil that represents an insect is one of the biggest ones on record.
Kaiju: One of the largest Devils in the entire series; exceeded only by Typhoon and Gun.
Rapid-Fire Fisticuffs: One of its attacks is to hurl Denji into the side of a building and then pummel the entire thing with its remaining arms.
Sadistic Choice: Tries pulling this on Denji by dropping a student and a car with five people inside from a fatal distance in the air. It didn’t expect Denji to ignore both options and instead kill it as fast as possible so he could save a cat instead.
Starter Villain: Denji's first opponent in Part 2, who while apparently strong and dangerous only serves to showcase how powerful Denji has become.
Wrong Genre Savvy: Cockroach assumes a "superhero" like Denji would be easily distracted agonizing over protecting as many people as possible, completely missing that Denji is the impulsive, self-motivated lead of an incredibly cynical series where the lives of the bystanders the devil threatens are simply fodder for Black Comedy.
Your Size May Vary: While the Cockroach Devil is consistently very very big, its exact size seems to vary between panels, going from the same size as the Bat Devil (who, while large, isn't unbelievably so) to being large enough to hold a car in one hand.

Nuclear Weapons Devil

The Devil embodying the fear of nuclear weaponry, and one of the Devils Pochita consumed as the original Chainsaw Man. For currently unclear reasons, the War Devil seeks to resurrect it.

Ambiguous Situation: It isn’t clear if War wants Nuclear brought back for the obvious reason of increasing the fear felt towards their own Name, or some other sinister purpose.
The Ghost: Pochita ate it some time ago, so we have no idea what it looks like.
MacGuffin Super-Person: Seeking to retrieve it is the whole reason Yoru involves herself in Asa and Denji's lives.
Posthumous Character: It's been gone for quite a while, though the nature of Pochita's ability means there's no telling how long ago that happened or what effect it had on the world.
Ret-Gone: As a Devil consumed by Pochita, it was retroactively deleted from history and so was its associated concept. Nonetheless, a certain few powerful Devils are able to recall it, albeit dimly.
Suspiciously Similar Substitute: To the Gun Devil, as a terrifyingly powerful weapon-themed Devil who is important to a villain's plans while spending most of the plot offscreen.

Falling Devil's Customer (Unmarked Spoilers)

Justice Devil

https://static.tvtropes.org/pmwiki/pub/images/devil_customer.PNG

An unknown Devil who the Falling Devil "cooks" for, with the dish in question being Asa Mitaka. After it is slain, Public Safety identifies it as the real Justice Devil.

Asshole Victim: It spends its entire screentime eating people and tearing apart the city to try and make a meal of Asa. When Nayuta makes it throw up its planned meal, the Falling Devil is so offended that she turns it into a red splotch on the ground.
Astonishingly Appropriate Appearance: It's a very hungry Devil, and apparently has a makeshift bib as part of its body. When it is later revealed as the Justice Devil its bib can also be seen as the robe of a judge and its ability to turn its hand into hammers evokes the image of a gavel. Not to mention that it appears to lack eyes thus being blind.
Big Creepy-Crawlies: It greatly resembles a giant caterpillar.
Chekhov's Gunman: It's seemingly only important as a minor enemy to Asa and Denji, not even being named. It's actually the real Justice Devil, revealing that the powers gotten by the Church of the Chainsaw Man and those around Asa are coming from something else pretending to be it.
Combat Tentacles: In Chapter 130, it tries to attack Denji and Asa with these, all of which appear to be worms with fanged mouths.
Disproportionate Retribution: Because of Nayuta fiddling with its brain to make humans taste like actual shit, the Devil throws up the meal given to him by the Falling Devil. The Falling Devil obliterates it out of pure rage for the perceived insult to her cooking, even crying tears of blood.
No Name Given: It when unnamed within the arc it appeared in, despite its role in hunting down Asa/Yoru and trying to eat them at the Falling Devil’s behest. Several chapters later, it's identified by Public Safety as the Justice Devil.
The Reveal: It's the real Justice Devil, and the fact that it's been in Hell the whole time before the Falling Devil showed up, and dead afterward, means that nobody actually contracted with it. Someone else is using its identity to cause problems at Denji and Asa's school.
The Scapegoat: It eventually comes to light that it is the real Justice Devil, who was never the source of the school's chronic Devil problems.
Shout-Out: The Devil's design and personality seem to be based on the famous children's book The Very Hungry Caterpillar.
Small Role, Big Impact: It's a one-off menace whose presence and power are eclipsed by the Falling Devil. However, the reveal of its identity as the Justice Devil casts doubt on everything we thought we knew about the events of Part 2.
Super-Persistent Predator: Even when Denji and Asa escape Hell thanks to the fake Chainsaw Man, it still pursues them (if only because the Falling Devil will kill it if he doesn't eat Asa).
Walking Spoiler: The reveal of this Devil's identity brings up a lot of implications about previous events in Part 2.
Waterfall Puke: Throws up Asa and Denji this way and is promptly killed by an infuriated Falling Devil.

Guillotine Devil

See the Chainsaw Man Church's page

Debuted in side materials

House Devil

The Devil representing the fear of mansions, appears in Power and Denji's arc of the light novel spin-off Chainsaw Man Buddy Stories.

Hidden in Plain Sight: The devil hunters investigating the mansion believe a devil is sneaking around the manor and picking everyone off one by one; it's only after Denji disappears that it becomes clear that the mansion itself is the devil.
Hollywood Acid: Its main way of killing anyone who dares to wander inside its body. It manages to digest half of Denji during its fight with him before being forced to expel him.
Living Structure Monster: The House Devil is basically a giant sentient mansion whose internal architechture mirrors that of a living being.

Mannequin Devil

The Devil representing the fear of mannequins, appears in Quanxi and Kishibe's arc of the light novel spin-off Chainsaw Man Buddy Stories.

Ditto Fighter: It mainly copies appearance of other people to fight, therefore gaining their power as a result.
Touch Telepathy: Uses its mind-reading powers to analyse its targets and pick on their weaknesses.

Fiends

Fiends (Majin in Japanese) are entities created by a Devil on the verge of death possessing a human corpse to survive at the cost of most of their power and ability to make Contracts. As their human-level intelligence and greatly reduced strength makes them relatively easy to manage compared to Contracted Devils, many are employed as Devil Hunters.

In General

Artificial Hybrid: They're effectively Devil/human hybrids in body, though usually all-devil in mind.
Disability-Negating Superpower: If the Gun Fiend's regrown arm is any indication, a devil possessing a body to become a fiend heals injuries, whether from or before their death.
Dub Name Change: The English version translates "majin" as "fiend", when it would more literally translate as "Devil(wo)man".
Human-Demon Hybrid: They're devils that have permanently merged with human corpses.
Logical Weakness: Though they can drink blood to recover from much more than normal humans, having to inhabit a human body means Fiends have all the same vulnerabilities to injury, starvation, etc.
Kishibe: Your muscle and skeletal structure is the same as ours. Snap the neck and you can't move.
Mars Needs Women: If Quanxi's girlfriends are anything to go by, fiends' bodies come with a human sex drive and may be attracted to humans and the other fiends in their bodies.
The Mind Is a Plaything of the Body: While they maintain Devils' sadism and bloodlust, Fiends may also desire things like human food and sex. While many Devils don't appear sapient, nearly every Fiend is, and they may have somewhat more capacity for empathy.
Mysterious Past: The act of becoming a Fiend is said to be a desperate last resort for a Devil, yet with the exception of the Gun Fiend, the circumstances behind how and why any of the known Fiends became as such is never revealed.
Non-Human Head: The primary identifying feature distinguishing them from actual humans is that their heads always have some trait that references the fear that created them, such as Cosmo's exposed brain.
Possessing a Dead Body: They inhabit already-dead human corpses, and are stuck in them for the rest of their lives.
Power Limiter: Regardless of how feared their Name is, a Fiend is always far weaker than their pure Devil counterpart. Which is presumably why some that have extremely feared Names (such as Blood, Cosmos and Violence) are less dangerous than the likes of the Bat and Fox Devils.
Red Right Hand: Fiends always have something inhuman to their faces/heads, including deformities, extra eyes, and animalistic feature.
Sexy Dimorphism: Fiends made from male bodies have either the upper or lower parts of their heads heavily transformed (insectoid mandibles, multiple eyes, etc.) whereas those made from female bodies tend to have much of their facial features preserved with telltale signs of their inhumanity usually being less grotesque.
Transformation of the Possessed: A devil possessing a corpse transforms part of it, almost always the head, to resemble the devil's original form.
Trapped in the Host: They're Devils merged with human corpses, a merger they can't undo for the rest of their lives

The Fiend at the Front Door (Unmarked Spoilers)

Aki Hayakawa / Gun Fiend

https://static.tvtropes.org/pmwiki/pub/images/gun_fiend_digital_color_version.jpg

Makima: The Gun Devil appeared without warning. We failed to defeat it. It took over a dead body and got away. That Gun Fiend is now ringing your doorbell.

When Aki is brainwashed into fighting beside Makima against the Gun Devil, he ends up as one of its many victims. When the Gun Devil is defeated, it is put into Aki's body. The resulting fiend came to confront Denji at their apartment, killing many of their neighbors and forcing Denji to put him down. All the while, Aki's consciousness believed he was a kid again, playing in the snow.

Ambiguous Situation:
- The Gun Devil ended up in Aki's body offscreen, so we can't be sure if it was an actual escape attempt as Makima said or if she forced it in as part of her plan.
- What, if anything, mentally remains of the Gun Devil is unclear. The Gun Fiend kills everyone in sight while Aki believes they're just playing, which could be Makima's deliberate influence or an accidental hallucination.
- Was it possible for Aki's personality to regain sanity and take control? The Violence Fiend showed a human body's mind can sometimes dominate a fiend's personality, but that doesn't mean it would have been wise or responsible for Denji to hold out. The last scene from Aki's perspective has him give up on the "snowball fight" when he sees Denji crying, after which the Gun Fiend may have stopped attacking as he was run through. Denji isn't sure and Makima guilt trips him by pressing on the possibility he Gave Up Too Soon, not that she's a reliable testimony.
And Then John Was a Zombie: After Makima's attack on the Gun Devil, it ends up fusing with Aki, mind still partially intact, turning Aki into the very thing he wanted so desperately to kill.
Arm Cannon: His forearm morphed into one of the many weapons making up the Gun Devil's body, specifically an AR-style rifle.
Astonishingly Appropriate Appearance: The pistol in his head doesn't stick out the back as far as in the Gun Devil; instead, Aki's topknot turns into the hammer.
Bishōnen Line: Inverted. After taking the body of the handsome Aki Hayakawa, the Gun Fiend is weak enough that Denji can actually fight him on equal terms, which would be utterly impossible against the monstrously powerful Gun Devil.
Body Horror: Aki's head, in a grotesque mockery of Denji's Devil form, has a gun sticking out of the still very much human skull, with the hammer imitating his topknot. It's... not pretty, to be blunt.
Book Ends: The first Devil hunting assignment he went on with Denji had them handling a newly born Fiend. The last one they're both involved in involves the same, except with Aki as the target.
Clipped-Wing Angel: As with any other fiend, seeking refuge in a human body made the Gun Devil much weaker. The Gun Fiend can blast buildings to pieces, but Denji can match blows with him, whereas doing the same to the Gun Devil proper would be absurdly impossible. Oddly, this a rare example of a villain's final transformation making for a more personal, emotionally-affecting confrontation with the protagonist.
Cope by Pretending: The less intentional view of Aki's vision is that his mind can only handle the stress of being killed and merged with the devil he most hates by pretending he's happy with his entire family (even his Family of Choice which never met the other half)—with absolutely disastrous consequences for everyone around him.
Death by Irony: Aki gets killed by the Gun Devil only to get possessed by it and turned into a Gun Fiend and has to be put down by Denji. In other words, he literally became the monster he had dedicated his life to hunting.
Disability-Negating Superpower: Zig-zagged; turning into a fiend regenerated Aki's lost arm, but then everything below the elbow was turned into a gun.
Dying Dream: As he's killed by Denji, Aki's snowball fight fantasy becomes one where he's reunited with his little brother and the two play catch just like he promised before their family died.
Go Out with a Smile: Aki dies dreaming of finally playing catch with his little brother, and the Gun Fiend appears to be smiling as he lays dying from being impaled by Denji.
Ignorance Is Bliss: In an extremely twisted way, Aki's warped visions let him die happy after wasting his life on a hopeless revenge quest. He's spared knowledge of the atrocities his body get used for—which may have worsened them by preventing his resistance. The Future Devil even chimes in afterward about how Aki died in the worst possible way for Denji.
Impaled with Extreme Prejudice: Denji kills the Gun Fiend by shoving both arm chainsaws through his chest at once.
Irony: After spending his entire career as a hunter trying to minimize civilian casualties to the point of attempting to subdue rather than kill most human attackers on his person, Aki winds up accumulating the largest kill count depicted onscreen attributed to either man or Fiend.
Lotus-Eater Machine: The more malicious interpretation of Aki's hallucinations is a deliberate effort by the Gun Fiend or the Control Devil to sedate and manipulate the human host's mind into doing their bidding.
Meaningful Name: Aki's name is close to "AK", a common abbreviation for the Avtomat Kalashnikov lines of assault rifles.
Perpetual Smiler: The Gun Fiend has the same Psychotic Smirk the whole time, even as he died. Disturbingly it's not out of sadism, he's just that lost in his happy delusions.
Psychotic Smirk: Played with; the Gun Fiend continuously smirks throughout the fight, even carrying one upon his death. This however isn't due to the trope's usual sadism, but because his mind is so broken that he interprets the entire fight he's having with Denji as a snowball fight.
Shoot the Shaggy Dog: Owing to Aki being a deconstruction of the Stock Shōnen Rival, his entire arc in the story ends on a downer note. He's so driven by his goal of killing the Gun Devil that he ultimately loses the majority of people he cares for and sacrifices both his body and lifespan to see his goal through. He does all of this only to learn that the Gun Devil had already been defeated and he later gets used as a pawn by the woman he seemingly loves and possessed by the Gun Devil, becoming the very monster he had been hunting.
Through the Eyes of Madness: After the massive traumas of being killed and then fusing with the Gun Devil, his mind interprets his incredibly violent battle with Denji in their devil forms as a Snowball Fight.
Walking Spoiler: The Gun Fiend's very existence ties into the reveal that Makima is the true Big Bad of Part 1 and that the Gun Devil had already been defeated years ago, as well as spoiling Aki's death.
You Can't Fight Fate: Despite all his efforts to prevent it, Aki truly had the worst death possible: First, he is mind-controlled by the woman he loved, then he gets killed and possessed by the devil he swore to kill. As the Gun Fiend, he goes on a shooting spree killing countless innocent people before being put down by his best friend. Everything went just as the Future Devil foresaw.

Loneliness Fiend

The Devil representing the fear of loneliness, appear in Aki and Himeno's arc of the light novel spin-off Buddy Stories. It occupies a body and wreaks havoc in an apartment complex, prompting the duo of devil hunters to go after it.

Lonely Together: It launches arrows at its target. However, the shot person won't die, but makes their loved ones perish instead, leaving them all alone. Aki speculates that aside from the fear it embodies, it is partially because the Devil inherits some memories of its host as well.

The Four Horsemen (Unmarked Spoilers)

In General

A four-strong group of extremely powerful Devils consisting of Control, War, Famine, and Death. Prior to the start of the story, they engaged Pochita in an extraordinarily fierce battle in Hell that left him in the weakened state Denji found him in.

By the present day, the group appear to have split up to pursue their own agendas.

Aliens Love Human Food: None of them express common devils' desire for human flesh, instead eating the same food humans do. For Nayuta and Fami, human civilization is worth preserving purely because they like the food it makes.
Bad Boss: Grossly abusive of their underlings, partners, and nominal teammates.
Big Bad Ensemble: They are definitively the main antagonists of the series, and the source of every major conflict, even amongst themselves.
Blessed with Suck: A commonality in Control and War's powers is that using them to their full potential requires a very unpleasant mental state.
Chekhov's Gunman: Control briefly mentions the other three Horsemen while fighting Pochita, but it wouldn't be until after she was defeated that they begin appearing in the story.
Dysfunctional Family: The four Devils are all sisters, but none of them save Famine like each other and even that has its limits since she's plotting to stop Death's advent.
Enemy Civil War: The Horsemen's interests are at odds more than aligned, as Pochita's full power was basically all they could agree to fight together. The elder Control lists the other three among the Devils she plans to erase once she claims Chainsaw Man’s power. Her next incarnation is broadly disinterested in her sisters' schemes, just trying to keep to herself and protect her Family of Choice. After getting stranded on Earth while weakened, War seems desperate to avoid the others. While Famine asks politely for the new Control's help, she mostly tries to coerce or manipulate the same from War. Death is the one Famine wanted to unite other sisters against because she's trying to cause the apocalypse.
Enemy Mine:
- They all allied together against Chainsaw Man, managing to severely weaken him, although the War Devil met the same fate in the process.
- After several manipulative schemes fail, Famine gets War on board with the Chainsaw Man Church by pointing out the Chainsaw Man the sisters fought long ago isn't Denji. This turns out to be another of Famine's schemes, though one that would give Yoru more power.
Evil Versus Oblivion: Control and Famine have both gone to war with Death to stop her from wiping out humanity.
Evil Is Petty: They tend to be motivated by basic desires and sometimes do strange things for arbitrary reasons; Control actively wants to remove bad movies from the world (as part of her Control Freak nature), Yoru kisses Denji after specifically being warned that it was a bad idea, and Famine's entire reason for trying to avert the apocalypse is because she doesn't want to lose her favorite foods.
Exotic Eye Designs: The three members encountered so far share a concentric, ringed eye design, Control’s being golden, War’s being red, and Famine's being pink. They are almost certainly Stylized for the Viewer, as no character mentions these eyes or uses them to identify the Horsemen as devils or related to each other, not even the Horsemen themselves.
Historical Gender Flip: The riders in the Book of Revelation were described as male, but all of the Four Horsemen in this series are female.
Horsemen of the Apocalypse: A group of extremely powerful Devils embodying and possessing powers themed for the same concepts the four figures of Christian myth are named after. Interestingly, Famine implies that they're all family, or at least she considers them as such. If so, though, it doesn't seem to be very loving. Ironically, while they're all involved with a prophesied apocalypse, only Death is actively seeking it. Famine is trying to stop her, dragging War into her plans, though causing smaller disasters in the process. The earlier incarnation of Control also wanted to stop Death, but to cause a different apocalypse on her terms, while the current incarnation can't be bothered either way.
Humanoid Abomination: They are the most human-looking pure Devils that the series has shown us, and given the rules of how Devils’ appearances match their behavior, they are the most comprehensible psychologically. However, they're all incredibly powerful, with strange and mysterious abilities that explicitly prey on those with weak minds.
Implacable Man: They will never stop chasing after Chainsaw Man for their own goals as long as they live, having followed him from the depths of hell to Japan.
- Control was the first to find him and recruited him into Public Safety as part of her plans.
- War investigated his whereabouts after Control's defeat and sought out a suitable host with which to infiltrate his school.
- Famine had the same idea and is currently undercover as part of the school's Devil Hunter Club.
It's All About Me: The main personality trait all of the known Horsemen have in common is being supremely selfish; their own goals are the only things that matter to them, and any aid they seem to provide to others is only in the service of their whims and desires.
Mythology Gag: They appear here in the same order as Book of Revelation with Control the first, War, the second, Famine the third, and Death the last.
Nice Mean And In Between: None of them are actually "nice", but their outward personalities contrast. Control maintains an aura of compassion and politeness right until the moment she stabs you in the back. War is loud, touchy, belligerent, and extremely aggressive. Famine is very calm, mannered, and polite to everyone, but unlike Control she doesn't even bother to hide her ill intentions for Asa.
Non-Indicative Name: Besides being women with a masculine title, they're called "Horsemen" despite having nothing to do with horses. This is because the Japanese term "Kishi (騎士)" has the kanji for "horse-riding" in it but is used more to mean "medieval knight".
One-Gender Race: They're all female, including both shown incarnations of Control.
Psychoactive Powers: Their powers so far share a dependence on their mental state, specifically their perception of themselves to others.
Red Right Hand: Their ringed eyes appear no matter what form they take. Well, to us anyway.
Ripple-Effect-Proof Memory: The Horsemen appear to to be the only entities in the world able to recall the existence of the Devils “eaten” by Chainsaw Man.
Shared Family Quirks:
- They're all face-blind. Control admits long before revealing her true nature that she can't discern faces, and goes by smell. Yoru and Famine also struggle to tell people apart, and are unable to discern Denji-as-Chainsaw Man from Pochita in his true form, despite looking very different, by anything besides color.
- They all seem to have an affinity for bread. At the end of Part 1, Denji asks Nayuta if there's anything she wants to eat, and she replies with sliced bread. After the Falling Devil arc in Part 2, Yoru celebrates mankind supposedly getting into another war with some slices of plain bread. Immediately after that, Fami pops into Asa's apartment and eats a whole loaf of bread as a snack.
She Is the King: Despite being called the Four Horsemen, all of them are female. The term in Japanese is "４人の騎士 (Yonin no Kishi)", which is gender-neutral and literally translates as "Four Knights^or", but the biblical term it was derived from was specifically masculine. There's also Death's alternate title as the "Great King of Terror".
Sibling Rivalry: The events of the entire series are revealed in Part 2 to be the 4 sisters having a very nasty family dispute on how to shape the world, with Pochita and everyone else caught in the crossfire.
Strange Minds Think Alike:
- While Control was pressed into it in Part 1, half of them independently thought it was a good idea to join a Devil hunter organization (the same one, in fact) during Part 2 despite being surrounded by potential enemies to further their aims.
- Fami and Nayuta both think that human foods, pizza in particular, are the real reason to keep the world intact.
Stylized for the Viewer: Their trademark ringed eyes are either not visible or not noteworthy to the other characters within the setting, not even other Horsemen.
Walking Spoiler: Discussing them involves giving away practically everything about the story.

In General

"L’an mil neuf cens nonante neuf sept mois
Du ciel viendra un grand Roy d’effrayeur
Resusciter le grand Roy d‘Atigoulmois,
Avant apres Mars regner par bon beur."

— Nostradamus's prophecy, quatrain X.72

A group of Devils and a final "ultimate terror" predicted in the Prophecy of Nostradamus that Fami claims will usher in The End of the World as We Know It and bring about Hell on Earth. Given Nostradamus's prophecy ends with a mention that, to paraphrase, "Mars will reign", the War God of Classical Mythology, Fami has become convinced her sister Yoru/War Devil is Earth's best shot at putting a stop to this Bad Future, and intends to pit Asa and Yoru against these Devils.

Historical Villain Upgrade: A real-life 16th-century French prophecy by Nostradamus, which in Chainsaw Man are a group of Arc Villains and the Greater-Scope Villain.

Falling Devil

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2023_03_14_110728_5.png

"Now then, allow me to begin cooking."

The Devil representing the fear of heights and falling. Given the instinctive unease and anxiety the idea of falling is associated with, she is a Primal Fear. She acts as a "chef" for the other devils, making her victims fall up into doors leading to Hell. Aside from grabbing up as many humans as she can, Asa and Yoru are her main target.

Affably Evil: Falling is a surprisingly polite and cultured Devil familiar with human customs, even as an antagonist. Even the reason she came to Earth is to "cook" for her fellow Devils, despite Devils having no real camaraderie and equally prone to killing and eating each other along with humans. And while she clearly has no problem with killing humans, she avoids killing more than necessary, as she opts to just take body parts she needs without killing their hosts and is cordial to a market employee she’s stealing from.
Almighty Janitor: For a Primal Fear with nearly godlike power who neither Denji nor the Fake Chainsaw Man can defeat, let alone kill, Falling is surprisingly humble and presents herself as a mere servant eager to please with her "cooking". Even Yoru wasn't sure what kind of Devil she was at first.
Yoru: Trauma. Gravity. Moon... Suicide... No, this Devil makes your hair stand on end. The fear is more primal than that.
- It's revealed that she was technically a servant for Famine at that particular point in time.
Ambiguous Situation: The Falling Devil is stated to be one of the Death Devil's "shepards" who will herald their coming. She's later revealed to be working for Fami, who's goal is to stop Death's arrival, making it ambiguous as to whether the Falling Devil is also trying to stop Death or if Fami simply hired her under the premise of feeding Asa to the denizens of Hell.
Ancient Evil: Like Darkness before her, Falling is an ancient Devil that has never experienced the cycle of death and rebirth typical for devils. She has existed as the same being throughout history, representing an instinctual fear common among all living things.
Arc Villain: Following Asa being sent off away from Denji after Nayuta rewrites her memories, Falling arrives on Earth and takes over the storyline with her quest to provide the innumerable Devils of Hell with as many meals as possible, including humans such as Asa. She is the first of many Shepherds who will herald the arrival of the Death Devil. However, it turns out Fami requested her assistance specifically to help her prevent Death from ushering in a World of Devils.
Bad Samaritan: Devils she feeds are tacitly obligated to finish the courses she serves. If they fail to do so before sunrise, she will hunt down and kill them for the perceived insult. And should one of those dishes involve a still-living combatant who can do them harm like the War Devil of the Four Horsemen, that is also entirely their problem.
Beast of the Apocalypse: Fami describes her as "the first of the devils who will shepherd the world to the ultimate terror". Although Falling actually came at Fami's behest, in an attempt to stop said terror. It's not clear if Fami was willing to advance the prophecy in an attempt to stop it, actually talking about a different devil, or lying to Yoshida for some reason.
Berserk Button: Although not outright stated, Falling Devil does not like it when you don't finish eating the meals she's prepared. She declared to the devils she's serving that she will kill them all if they don't eat everything, including "dishes" that are making a run for it like Asa and Denji. And if you throw up her food, she will obliterate you. The devil she was serving found this out the hard way when Nayuta fiddled with its sense of taste, making humans taste like actual shit.
Beware the Silly Ones: Falling's bizarrely affable mannerisms revolving around cooking and the idea of being a chef, which don't even have any connection to the fear she embodies, as well as her tendency to actually get injured in combat (albeit with absolutely no permanent effect) lends her a certain comedic air around her appearances. Especially when compared against the Darkness Devil's inscrutable powers and objectives, it can be easy to forget that she's still a Primal Fear. Every so often, however, Falling does execute some terrifying or awe inspiring action that reminds the viewer that she is not to be taken lightly.
- Her very first appearance is her causing everyone in an apartment complex to suddenly commit suicide so that she can manifest a body out of their collective remains. They aren't mindlessly compelled to their deaths or forcibly dragged off the edge—they just all, as one, calmly decide that they want to die.
- Despite constantly getting shredded by Public Safety and Denji, it's heavily indicated that she isn't taking their attempts to stop her seriously, as nothing they do to her causes any lasting harm whatsoever and she's shown to be capable of razing whole city blocks with effortless flicks of a finger.
- The one time she's actually angered by a Devil throwing up its meal, Falling destroys it with an incomprehensible attack reminiscent of the Darkness Devil, exploding it inside out with the point of a finger.
- It's later revealed that her mere appearance on Earth was causing intense gravity fluctuations worldwide, resulting in cave ins and landslides across the entire planet with an unknown death toll.
Blue-and-Orange Morality: Unlike many devils, the Falling Devil dislikes hurting people for its own sake, but will casually do so for unusual reasons. She'll mutilate, kill, psychologically torment, and Mind Rape humans to make food from them, then chats up a store clerk while dismissing her fear for her life. Said "food" is to feed Falling's fellow devils, who she'll kill if they don't eat everything—even if it's taken away against their will! There may be some higher goal to all this, but this may just what the Falling Devil considers part of being a chef.
Body of Bodies: Builds a body for herself out of the various corpses of her victims. She has one head she speaks and emotes through, but it isn't attached, it's just held aloft by arms.
Break Them by Talking: When she encounters Asa barely hanging on from falling into the sky, though the Falling Devil could easily force her to let go, instead she gently encourages her to let go of her own volition by promising the pain Asa’s dealt with all her life will come to an end, essentially encouraging her to commit suicide. And it works. Fortunately, Denji shows up to catch her.
Can't Take Criticism: When a devil vomits up her meal, she starts to cry, throws a tantrum, and kills it.
Chest Burster: When Denji proves to have a way to circumvent being hurled into the Despair Event Horizon, and attacks too fast and ferociously for her telekinesis to get rid of him, Falling allows him to eat her so that she can instantly regenerate while still inside his stomach, tearing him in half and knocking him out in the process.
Consummate Professional: The Falling Devil considers feeding humans to the denizens of Hell as a job to do, one that she wants to go about as efficiently and promptly as possible, displaying none of the wanton sadism of fellow devils. She only really gets rude towards Denji when he stalls her from finishing her job.
Contrasting Sequel Antagonist:
- Falling is the second Primal Fear to appear in the series, and couldn't be more different from Part 1's Darkness. Whereas Darkness was horror incomprehensible to humans, Falling demonstrates a keen understanding of people and uses her vessel to speak normally. She also expresses modesty and dresses in clothing, basing her entire persona on a high-class chef. Whilst Darkness only attacked humans that intruded upon Hell, Falling took the offensive and arrived on Earth to sow chaos. Additionally, Darkness was very much The Dreaded towards other devils, to the point where they'd rather commit suicide than face it, while Falling seems to feel some sort of kinship with her kind and is providing food for them. After the abomination that was Darkness, Falling is startlingly human. Additionally, unlike Darkness, who actively targeted Denji and formed a contract with Santa Claus to accomplish that, she has no interest in Chainsaw Man or his heart and only fights Denji because of his persistence; in fact, she's willing to let him (and only him) leave Hell when he gets sent there.
- One can compare her to Santa Claus's Doll Devil form as well - while Santa Claus was a sadistic monstrosity operating in the nude that loves torturing her victims through A Fate Worse Than Death, Falling merely acts professional akin to a human chef, and opts for quick deaths for her human targets, if she kills them at all.
Dragged Off to Hell: When she manifests on Earth, the Falling Devil starts sending humans upward into doors to hell, presumably with hungry devils waiting on the other side. Whether she or someone else is making the door isn't clear.
Dragon-in-Chief: She turns out to be acting on behalf of Famine, who prefers to remain in the background while Falling quite literally turns the city upside down with the intent of landing Asa and Yoru inside a Devil's stomach in the hopes that it will subvert the Prophecy by starving them into becoming Fami's pawn, helping her stop Death.
Emotion Bomb: One application of her powers allows her to make those around her "fall" into despair, reliving their past traumas. Even before that, her summoning is brought about by her suddenly inducing suicidal feelings in the residents of an apartment building.
Even Evil Has Standards:
- Surprising for both a Devil and a Primal Fear, but she admits she prefers to avoid meaningless slaughter, and, if a human is not needed as an ingredient, she says she won't harm them so long as they don't attack her first.
- She also rightfully calls Denji a pervert when his priorities are to ask if he could at least keep Asa's ass if he wasn't allowed to save her. This was after she offered to let him go if he left Asa behind.
- Both she and Fami want to stop the Death Devil from ushering in the World of Devils, even though Falling is one of the Devils who will shepherd the world to the Death Devil's arrival.
Evil Chef: She dons a chef outfit upon manifesting and announces she's come at the request of the residents of Hell to serve her fellow devils "meals" consisting of people. Not only does she use her powers to "season" humans by making them experience powerful emotions, like past traumas, but she also prepares dishes comprised of specific body parts along with normal food.
Exotic Equipment: She has a very phallic-looking tentacle on her crotch. An earlier version of her design seen in a leak had two tentacles there that very blatantly came together like a labia.
Eyes Always Shut: The head she uses started out with her eyes open, but once fully assimilated, the head's eyes remain closed as Falling goes about her "cooking".
False Reassurance: Gets Asa to give up on resisting her attack by promising that the fall will be painless, that the young woman won't feel the shock of hitting the ground, and that it will bring about an end to her troubles. She neglects to tell her that said fall will bring Asa to Hell, whereupon she will be painfully Eaten Alive by Devils.
Fan Disservice: At first glance, Falling's tall body seems very busty with an hourglass figure when clothed. However, this is simply an illusion created by a malformed and twisted torso, drawn at angles that create a more alluring image. In reality, the chest is jutting out at an impossible angle and the waist looks like it was twisted around several times before being attached to a mismatched pelvis. And what she has between her legs is a weird eldritch body part, like a remnant of an umbilical cord.
Fed to the Beast: She feed humans alive to other devils, usually by having them float up into doors to hell. After she's attacked by a Public Safety team and captures the last living one, she goes to the extra effort of stitching his mouth shut, prying his eyes open, and contorting his paralyzed body to hold a soup bowl full of his partner's body parts, all of which she personally rolls up on a dolly to a giant slug-like devil wearing a bib. The next panel has her getting splattered with the man's blood.
Gravity Master: Falling's M.O. and the reason she's a nightmare to deal with. She has a passive aura that causes people to fall up into Hell if they give into despair, and can make things "fall" in whatever direction she chooses with a flick of her finger. The latter is strong enough to rip buildings in half.
Healing Factor: Sports one so rapid it's barely even visible. Any injuries inflicted on her simply disappear between panels, no matter how severe. In one panel, Public Safety guns have reduced her to a pile of gore; in the next, she's upright and completely untouched, with the last of her entrails whipping itself back into her body. Even her clothes get restored.
Hermaphrodite: Her physical form was created out of a pile of both male and female corpses, and this is reflected in her nude design; not only does she have breasts but she also has a crotch tendril akin to a penis—though the original design was much more yonic.
The Heavy: It turns out that Famine is the one who put her up to the task in the first place.
Horrifying the Horror: Her appearance at the end of Chapter 122 is enough to scare Yoru, one of the Four Horsemen. This makes some sense, based on the very nature of a Primal Fear as the strongest of all devils.
Humanoid Abomination: She fits the pattern established by Angel and Makima of "Devils that look like humans think like them too," although her twisted and many-limbed body still looks a bit more monstrous. However, unlike those two who naturally appeared human (Makima especially), Fallen's body is a constructed vessel made out of the corpses of her victims.
Invincible Villain: Nothing that Asa or Denji can do can even stall the Falling Devil. The only reason they survive is because of Nayuta causing the devil Asa is fed to into throwing them up, causing the Falling Devil to kill it in a rage, and thus becoming unable to fulfill Fami's task of feeding Asa to it.
It's Raining Men: She summons herself by causing the people in an apartment building to throw themselves over the balcony.
Kick Chick: Despite all the extra arms, in close quarters, she fights exclusively with her bladed tentacle or her inhumanly long legs.
Major Injury Underreaction: She's mildly annoyed at being blown apart repeatedly by Devil Hunters, and her response to Denji mauling her is a quip about being served up herself.
Mobile-Suit Human: Her Body of Bodies really is just an avatar. After she fails to fulfill her agreement with Famine and returns to Hell, her avatar crumbles and her true body falls out of it; it resembles a more monstrous version of her avatar, minus the head, but is only about the size of an action figure.
More than Mind Control: Besides attacking her mind directly, Falling preys on Asa's desire for relief to convince her to let herself be killed.
Multi-Armed and Dangerous: The avatar she creates out of a mound of corpses possesses several arms (some human, others blade-like).
Naked on Arrival: The Body of Bodies she uses as a vessel is naked after being formed, though her reaction is surprisingly human modesty.
Nice to the Waiter: She's attempts to be polite to the employee from the supermarket she's robbing, assuring them she has no intention of killing her unless attacked first. Then she continues to question her about which apples pair well with human flesh.
Nigh-Invulnerable: Of the regeneration variety. She claims nothing in the human world can truly harm or kill her and proves it by simply getting back up completely unharmed after being torn into shredded meat by concentrated gunfire. She heals so quickly that the Manga panels don't show it happening, she just suddenly appears untouched.
No-Sell: Devils consumed by the Chainsaw Man are supposed to be erased from existence, but for whatever reason when Denji consumes her while in Chainsaw Man form she just instantly regenerates inside his stomach, tearing him in half.
No Sense of Personal Space: When Asa is hanging off a ledge, Falling gets up behind her and starts feeling her face and commenting that she can smell her sweat.
No Social Skills: Falling will talk to humans casually, as if expecting her appearance and actions not to disturb them. For instance, she acts as if a supermarket employee is silly to fear for her life when Falling pins her to the ceiling.
Not So Stoic: Falling Devil conducts herself with professionalism, but she's shown to be actively annoyed by Denji's antics. She also cries Tears of Blood when the Devil she was making a meal for vomits it out, screaming in outrage as she made the meal with love. She promptly killed the aforementioned Devil in her rage.
Person of Mass Destruction: She can apply her Gravity Master powers to more than just people; when a devil hunter squad tries to eliminate her, she effortlessly razes a city block by making it fall upwards and then down again. In the aftermath of her rampage, it is revealed her arrival heralded gravitational imbalances which caused landslides and cave-ins all over the world.
Pet the Dog: When collecting apples for her next dish, she doesn't harm the worker at the supermarket she's getting them from, merely asking where she can find the ones that suit her needs.
Posthuman Nudism: Subverted. She pauses upon finishing making herself a Body of Bodies, and calls her nudity "indecent" before summoning a chef's uniform. For a Primal Fear, she demonstrates a surprisingly human attitude towards nudity in comparison to other Devils.
Primal Fear: Exactly What It Says on the Tin. She is one of the ancient devils known as a Primal Fear, a being that represents an ancient and universal concept with power sufficient to have never died and been reborn. In her case, she represents a fear of falling, either literally, like from heights, or metaphorically like falling into despair.
Psychic-Assisted Suicide: She's introduced after causing people in a building to commit suicide by leaping to their deaths so she can use all their bodies to physically manifest on earth.
Punch-Clock Villain: She displays little of the bloodlust and vindictiveness common among devils; despite the horror of her actions, she's just here to do the job asked of her, with a minimum of fuss and a maximum of professionalism, and intends to return to Hell of her own will after serving the final course. Which she does, after failing to complete the mission assigned to her by Fami.
Shout-Out: Her appearance and demeanor is evocative of The Menu, one of Fujimoto’s favorite stated films of 2022. Other elements of the movie include her cooking with death, which is a line said by a character in the movie, as well as announcing a dish by using a strong clap, which the Chef also uses with the same intention all through the movie.
Stealth Pun: She is both a Gravity Master and a performative Evil Chef serving food to Devils. She's a waitress serving up the weightless.
Tears of Blood: Once she assimilates a head into her body, it begins shedding blood from the eyes. Whether this is a trait of Falling or just the damaged head she's using is unknown, though it's implied to be the former after she reforms her body from an attack.
Too Spicy for Yog-Sothoth: Either Denji doesn't have access to Pochita's erasure abilities, or the Falling Devil is above his pay grade; either way, she's completely unfazed after he eats her and just erupts from his torso unharmed.
Unwitting Pawn: Played with. Chapter 131 reveals she was serving Asa Mitaka to the denizens of Hell specifically per Famine Devil's request, though she doesn't seem to be aware that Fami asked her to do so so as to "strengthen" Yoru.
Villains Out Shopping: After her initial debut of wrecking havoc by killing an untold amount of people via her powers, she then spends Chapter 125 going out to gather ingredients for her next dish. Said ingredients include four ears, ten eyes, and... apples. Which she gets by simply going to the supermarket. Granted, she does subject an employee to her powers, but ultimately doesn't harm her at all beyond pinning her to the ceiling. Unfortunately for her, Denji takes umbrage with the fact she didn't pay for them.
Walking Wasteland: Even after she leaves the story, her manifestation alone causes landslides and cave-ins worldwide.
Wicked Cultured: She conducts herself with elegance and class, concerned with her appearance and impeccable manners. Her entire motif is themed around cooking, of all things, and she behaves like one would expect of a high-class chef at a Michelin star restaurant.
Worf Had the Flu: Horrifyingly enough, yes. For as devastating as her appearance on Earth was, the fact that she was summoned as part of a contract with Fami puts her here, as in Chapter 157, Fami states that devils she summons as part of a contract are weaker than if they showed up on their own, with it being implied the difference is fairly significant.
You Have Failed Me: The Falling Devil came to earth at the behest of the residents of Hell to feed them humans, but when introducing herself, she promises any of them who don't finish the "food" she's prepared will "taste death." After Chainsaw Man saves Asa from Hell, the devils she was serving begin to pursue them, knowing Falling will kill them if they don't eat Asa, who she presented as their "main course". She kills the Devil anyway when it pukes up Denji and Asa because Nayuta screwed with its sense of taste.

The Great King of Terror (Unmarked Spoilers)

Death Devil

"Nostradamus's prophecy is coming true. The ultimate terror will soon descend on this world. If that happens, the age of humans will end... ushering in an age of devils."

— Fami

The most powerful Devil in existence, representing the primordial fear of death itself, and the fourth and eldest of the Horsemen of the Apocalypse. According to the Prophecy of Nostradamus, she will descend from the heavens in July of 1999 and lead Earth into a new era by bringing about the Age of Devils.

Ambiguous Situation: While Death is almost certainly very bad news, it's difficult to determine anything certain about Death, other than her strength.
Beast of the Apocalypse: Her subsequent appearance heralds the end of the world of humans, and the start of a world of Devils.
Big Bad: While she doesn't play a direct role as of the current arc, she's nonetheless the biggest source of conflict in Part 2.
Cain and Abel: Well, in this instance everyone involved is a Cain, but her younger sisters Control and Famine make it very clear that they're her enemy, and given that Yoru is central to Fami's plans there's little doubt that she'll also fight Death.
The Dreaded: As possibly the singular source of all fear, Death is, according to Nayuta, the most powerful Devil in existence and all others, even her sisters, fear her and will do everything in their power to prevent her from achieving her goals.
The End of the World as We Know It: If the Prophecy is accurate, she is destined to turn Earth into a world where Devils reign supreme.
Everybody Hates Hades: Death itself is not good or evil, merely an ending. But when it's conceptually represented by a Devil, we obviously begin to have very big problems.
The Ghost: She's first mentioned two in-series years before she's scheduled to appear on Earth.
Godzilla Threshold: Just the idea of her arriving on Earth has Famine doing everything she can to prevent the human world from dying off, such as summoning a Primal Fear who is apparently a Shepherd of Death, even if it is ultimately for petty reasons like "no more pizza or Chinese food, ever".
Greater-Scope Villain: As the most powerful Devil to ever exist, her very arrival will lead to The End of the World as We Know It, with Famine and Control (when she was Makima) seeking to prevent Death from obliterating the world of humans. So almost everything in the series happens because of her.
Hell on Earth: What Fami claims her arrival will cause, what with Devils spreading all over the world when she appears.
Horrifying the Horror: Even Control and Famine are highly wary of what Death's arrival means for the world.
Last of Its Kind: She is the last of the Devils representing what can happen to a human at the end of their life, after Pochita ate and Ret-Gone the others. This is also a partial source of her sheer strength because she has no more competitors, so all the fear that would normally be split amongst them is now directed solely towards her.
Mortality Phobia: The embodiment of it, which implies she's stupendously powerful even by Devil standards; Nayuta outright confirms that she is, in fact, the most powerful Devil in existence, surpassing even Darkness. Most other fears stems from the threat of being harmed and potentially dying in the process, thus feeding directly into Death's power.
Omnicidal Maniac: If the Prophecy if Nostradamus is to be believed, her main goal is to destroy Earth and drive humanity to extinction.
Primal Fear: Death is the ultimate primal fear for humanity since all living creatures, most especially humans, have a Mortality Phobia out of natural survival instincts, with almost every other fear indirectly leading into a fear of it causing their death, which naturally means Death can stand to claim the title of World's Strongest Man over those like Darkness and Falling, with only the Inexplicably Awesome status of Pochita as Chainsaw Man attesting that claim.
She Is the King: The Great King of Terror is the female Death Devil.
Stronger Sibling: She is the alpha and omega of the Horsemen, far stronger than even her already mighty younger sisters, who consider her to be the greatest fear in the world.
Take Over the World: As the Great King of Terror, she will likely be taking her destined place as the planet's supreme ruler once the Age of Devils begins at her behest.
World's Strongest Man: Nayuta states in no uncertain terms that Death is the most powerful Devil of all. At the very least, the fact that she's confirmed to be stronger than the already revealed Primal Fears due to being the biggest Primal Fear makes it, at best, a two horse race between her and Pochita for the position.
