Artificial Humans (Nomus)
Monsters used by the League of Villains. These beings are actually experiments created by All For One in conjunction with the Doctor. The truth is that they're people who couldn't handle more than one Quirk, granted by All For One, which caused them to become mindless dolls.
- And I Must Scream: It's implied that the Nomus maintain a certain degree of their memories and consciousness, however, how much they are able to access and feel is unknown.
- Artificial Human: It's right there in the name. None of them look human at all, though.
- Body Horror: Each of them though differing in what their bodies look like, have one thing in common - the top of their head is missing, exposing their entire brain.
- The Brute: What they served as, muscle to be thrown at the Heroes to slow them down, weaken them and then kill them.
- Combo Platter Powers: Nomu are given whatever Quirks out of All for One's collection that he considers useful for them, often resulting in combinations of vastly different powers. This allows All for One to tailor-make them to fit whatever purpose he desires regardless of how powerful they were as humans.
- Degraded Boss: The U.S.J. Nomu was powerful enough to give All Might a significant challenge. While still powerful enough to battle an entire group of pro heroes alone, none of the Artificial Humans introduced later are close to being as strong or resilient as the U.S.J. one until Hood, a Nomu with far more intelligence and Quirks at its disposal being powerful enough to defeat Endeavor alone. All for One stated that their less impressive showings were due to being less refined than the first one, as well as the fact the U.S.J. Nomu was made specifically to fight and kill All Might and thus needed to be much stronger. Later justified when it becomes clear there are tiers of Nomu; when Hood strikes, Endeavor makes a distinction that black Nomus are more powerful and difficult to dispatch than the ones with white skin, as the one in Hosu that was black was also especially troublesome.
- Dumb Muscle: The Nomus are unable to think or rationalize things and only have the intelligence of a wild animal at best besides glimpses of their human memories, so they're only used like this.
- Elite Mook: The Artificial Humans created after the U.S.J. Nomu (except the High-End Nomus). More dangerous than the thugs used during the USJ Arc, but not as strong as the U.S.J. Nomu itself, with a few ones being more successful than others (like the one used during the School Trip Arc).
- Empty Shell: Nomu are made from victims of All for One that were unable to handle the Quirks he gave them, leaving them mindless husks which he then mutates into super soldier servants. Having no wills of their own, Nomu only act on direct orders from All for One or his chosen subordinates. Without orders to follow, Nomu become nearly catatonic and unresponsive to all outside stimuli making them easy to contain despite their power.
- Implacable Man: None of them care about pain or damage to themselves and will do as instructed no matter who tries to stop them. The first Nomu is perfectly okay even after being thrashed by All Might, it's just that without orders he has become totally docile.
- Knight of Cerebus: They're all this, just to different degrees. They're only brought out when shit goes down.
- Law of Chromatic Superiority: Nomus with jet black skin are said to be stronger than those with lighter skin. It's definitely the case with the U.S.J. Nomu and Hood, the latter being able to spawn White Nomus to back him up.
- Was Once a Man: All of them were once normal people until All For One got to them.
- With Great Power Comes Great Insanity: They have access to multiple (non-inherited) Quirks, but these were implanted into them at the cost of any brainpower or sanity they once possessed.

Debut: Chapter 11 (Manga), Episode 8 (Anime)
Quirks: Shock Absorption, Super Regeneration
The original Nomu, the League's strongman and a secret weapon to destroy All Might. His Quirks are "Shock Absorption" and "Regeneration", and he's incredibly strong even without the aid of other Quirks. He was created with the help of All For One and the doctor who serves under All For One.
- Adaptation Expansion: In My Hero One's Justice's story mode, it and two black-skinned Hosu Nomu that work as its assists are used to represent the Kamino Nomus during the Hideout Raid Arc.
- An Arm and a Leg: He has his arm and leg frozen and broken off by Todoroki. It doesn't last.
- Body Horror: First there's the matter of his exposed brain and then he has a bizarre beak-like mouth that permanently has his teeth showing. It's creepily reminiscent of the Mass Produced Evas. And when he regenerates, bone and muscle apparently need to complete before he regrows the skin.
- The Brute: He was the muscle of the League, having literally no character to speak of besides protecting Shigaraki and attacking what he's told to attack, which he does very well.
- Covered in Scars: This Nomu has multiple scars on its arms which are permanent, no doubt caused by experimentation.
- Dumb Muscle: Up to Eleven. He's designed to be only responsive to the League of Villains and a brutal opponent for All Might. That's it. If he's not in the presence of an enemy that he is reflexively programmed to attack, or not given any orders, he doesn't do much of anything at all. If he's restrained and captured, Nomu goes basically brain-dead. It's impossible to get any information out of him because he's like a vegetable. The police wondered why it did that, but really, Nomu has no reason to respond to anyone or anything outside of its directives. The other Nomus share that quality.
- Everyone Calls Him "Barkeep": When he first showed up, Shigaraki simply called him Nomu as if it were a proper name.
- Healing Factor: Has a "Super Regeneration" Quirk.
- Laser Guided Tyke Bomb: He was created specifically to counter All Might.
- Lightning Bruiser: He's fairly big and bulky, yet managed to zip straight to Tomura, and block Midoriya's punch in the blink of an eye.
- Logical Weakness: As All Might points out, his Quirk is Shock Absorption, not nullification. If it absorbs impacts, then there should logically be a limit to how much force it can hold, and it's just a matter of hitting the Nomu enough to overload it. Shigaraki also suggests gouging away his flesh with low-impact but abrasive attacks, but Nomu's Healing Factor means that won't defeat him, and he wouldn't just let them do it anyway.
- Muscles Are Meaningful: He's strong enough to match All Might and has biceps thicker than a human torso.
- No-Sell: Nomu could tank Izuku's punch without any harm due to his Shock Absorption Quirk. Even All Might had to spam over 100% One for All punches to get them to affect him.
- Put on a Bus: Nomu was lost to the League of Villains after it lost its fight to All Might (Kurogiri couldn't recover it, since he didn't know where Nomu landed). Nomu was later recovered arrested by the police, and still lacks the individual initiative to try to escape. By chapter 47 of the manga, it's still in police custody, and the League still doesn't appear to know about its fate.
- Super Prototype: He's the most powerful of the Artificial Humans created so far, as he was given Quirks specifically chosen to kill All Might, who's the World's Strongest Man. Not until Hood would another one close to its level come along.
- Super Strength: Eraserhead says Nomu's strength is incredible, even while he is trying to use his Quirk on Nomu at maximum.
- Super Toughness: His other Quirk, "Shock Absorption", allows him to absorb blows, even from All Might. This drove All Might to dig deep for extra power, and then spam punches to overwhelm this power.
- A Twinkle in the Sky: His ultimate fate is to get punched through the USJ dome hard enough that his apparent fate was to go into orbit. During the cleanup of the incident, he was later found in a tree on school grounds by the police, who recovered and arrested him.
- Wake-Up Call Boss: While most of the initial League of Villain's roster were second-rate thugs that couldn't even really challenge the students of Class 1-A in their first week of school, let alone the pros, Nomu was the first villain in the series to present a real challenge to All Might. Aizawa and All Might both note that the experience forced Class 1-A to realize what was expected of them as heroes and not to hesitate with their powers.
- Was Once a Man: Nomu used to be a petty thug. Then All for One got ahold of him and gave him four extra Quirks, rendering him both monstrously strong and almost completely mindless.
Debut: Chapter 50 (Manga), Episode 28 (Anime)
Quirks: Absorption and Release, Muscle Growth, Tongue Web (White-skinned Nomu), Super Regeneration (Black-skinned Nomu), Pterodactyl Wings (Winged Nomu)
A trio of Nomu that Shigaraki sent to attack Hosu to show up Stain. Comprised of a white-skinned, black-skinned, and special winged Nomu.
- Adaptation Expansion: The anime showcases Endeavor's fight with the black-skinned and winged Nomu's, which was only alluded to in the manga.
- The black-skinned Nomu gets a lot of extra screen time in My Hero One's Justice's story mode. Firstly, one mission has it fighting Gran Torino during the Hosu Incident, something that never happened in the anime or manga. Secondly, it takes the Chainsaw Nomu's place during the School Trip Arc. Finally, two of it serves as the U.S.J. Nomu's assist characters in order to represent the Kamino Nomus.
- Attack Reflector: One of the white-skinned Nomu's Quirks allows it to absorb attacks and release them back at others. The attacks still hurt it though.
- The Brute: The black-skinned Nomu is similar to the USJ Nomu, as it proves the hardest to defeat and the most resilient. Endeavor begins to realize that black-skinned Nomus are unique after seeing how hard it is to take them down compared to the paler-skinned ones. Endeavor is forced to carbonize its cells beyond the point of regeneration, killing it.
- Covered in Scars: Like the USJ Nomu, the black-skinned Hosu Nomu has scars on its arms.
- Cruel and Unusual Death: Endeavor burns the black-skinned Nomu's head clean off. Stain also stunned one and stabbed its brain.
- Death by Adaptation: Downplayed in the black-skinned Nomu's case. Its fate isn't clear in the manga, but the anime show its death.
- Growing Muscles Sequence: One of the white-skinned Nomu's Quirks allows it to do this temporarily.
- Healing Factor: The black-skinned one has a regeneration Quirk, a common trait among black-skinned Nomu.
- Logical Weakness: Kill It with Fire works great against the black Nomu because to regenerate it needs something to regenerate from. Its Healing Factor doesn't work if it's been reduced to ashes.
- Overly Long Tongue: One of the white-skinned Nomu's Quirks gives it this, effectively making it tongue-web.
- Spared by the Adaptation: Ambiguous. The news report in the anime says all three were captured, which indicates all three survived. However, given that we already know the news is inaccurate given that they're reporting that Endeavor captured Stain, it's not clear if the news can be trusted on the matter. It's also possible they counted retrieving their dead bodies as "capturing", which is especially likely as Endeavor is shown killing the black-skinned Nomu.
- Sole Survivor: In the anime, the white-skinned Nomu is the only one not to be killed, and instead is captured. This may also be true in the manga, as the black-skinned Nomu's fate is ambiguous (in the anime, Endeavor kills it by searing its head off).
- Was Once a Man: All of them are this, but the Winged Nomu is notable. It's implied in the Volume 7 omake that it may have once been the kid with wings - Tsubasa - who used to hang out with Bakugo and Deku back when they were children.
- Wind from Beneath My Wings: The winged Nomu can use its wings to create blasts of air to push back foes and fan fires.
- Winged Humanoid: The winged Nomu.

Quirk: Tool Arms
A member of the Vanguard Action Squad that attacked U.A. during the School Trip Arc. Its Quirk "Tool Arms" allows it to generate six arms from its body that end in artificial tools.
- Adapted Out: It's doesn't appear in My Hero One's Justice's version of the School Trip Arc, and is instead replaced by the black Hosu Nomu.
- Advancing Boss of Doom: When it attacked, it immediately delivered a severe head injury to Yaoyorozu and all Awase could do was temporarily weld her onto himself so she wouldn't fall off and RUN. They only survived because the order went out for the League of Villains to withdraw, just after Awase collapsed from exhaustion and the Nomu was seconds from claiming two innocent students.
- Bound and Gagged: It has a reinforced metal restraint clamped inside its mouth that holds its jaw open and probably stops it from having the urge to bite. Or making tortured noises.
- Chainsaw Good: Four out of its six arms have chainsaws on them.
- Gardening-Variety Weapon: One of its arms has a claw hammer on it.
- Multi-Armed and Dangerous: Thanks to its Quirk, it has eight arms, each of which could kill you.
- Shapeshifter Weapon: What its Quirk gives it.
- Small Role, Big Impact: It has very little screen time, barely totaling a minute. But because Yaoyorozu's tracking device was merged onto it, it is an essential aspect of the the next arc. Also, in the minute it was active, it was easily the most dangerous foe out of all the villains attacking the training grounds and would have no doubt struck down Yaomomo and Awase had a withdraw order not been signaled once the League captured Bakugo. It was also the one who beat down Ragdoll, allowing All For One to take her Quirk.
- This Is a Drill: One of its arms has a drill on it.
- Uncertain Doom: It can be seen in Mount Lady's hand during the after the Pro Heros find the Nomu Factory. And it's still in her hand when All For One blows the Pros away. While it is known the pros all survived, we never see the Nomu's fate.
Debut: Chapter 88 (Manga), Episode 47 (Anime)
The Nomu deployed by All for One against the heroes and police during the raid on the League of Villains.
- Adapted Out: They don't appear in My Hero One's Justice's version of the Hideout Raid Arc, and instead are represented by the U.S.J. Nomu with two black-skinned Hosu Nomu as assists.
- Blob Monster: One of the Nomus that attacks All Might is just a mass of slime with an exposed brain sticking out of it.
- Conservation of Ninjutsu: There's at least ten of them, but none of them are as powerful as the U.S.J. Nomu or even the chainsaw Nomu.
- Creepily Long Arms: One of the ones that attacks All Might has long arms with several extra elbows.
- Immune to Bullets: They're the only Nomus who've been shot at and it did nothing.
- Losing Your Head: One of the Nomus that attacks the police has no head, with its exposed brain protruding directly from its torso where its neck should be
- Malevolent Masked Man: Several of them have masks akin to the Hosu winged Nomu, and one combines this with Eyeless Face to give it a head that's nothing but a mask and brain.
- Multi-Armed and Dangerous: One of the Nomus that attacks the police has four arms.
- Palette Swap: In the anime, most of them are just differently colored versions of the Four-Eyed Hosu Nomu
- Primal Stance: Several move on all fours.
- Skull for a Head: At least two of them have this.
- Spikes of Villainy: One of the Nomus that attacks All Might has short spines all over its body.
Debut: Chapter 222 (Manga)
A small Nomu that the Doctor keeps in his lab. His Quirk is "Warping" — the same one All For One uses — and it allows him to teleport individuals to and from his current location.
- Armless Biped: Two legs, no arms.
- Body Horror: The doctor uses several dials hooked directly into his brain to control his Quirk, a process that looks unpleasant given the expressions he makes.
- Evil Smells Bad: The black ooze produced by his Quirk is said to smell really bad as Lampshaded by the Rabbit Hero, Miriko.
- Nice Shoes: He sports some childish-sneakers as his sole article of clothing.
- No Name Given: Averted, he's the only Nomu that's given an actual name.
- Support Party Member: His Warping is a useful tool for the League of Villains, but he's useless in combat.
- Villainous Rescue: The Doctor uses him to rescue Dabi after his confrontation with Endeavor is interrupted.
- Villain Teleportation: His "Warping" Quirk. It's much grosser than Kurogiri's "Warp Gate" as it involves enveloping whoever he wants to teleport in a black ooze that pours out of the target's mouth. When using it, the ooze also pours out of his mouth, which raises some disgusting questions about the specifics of his Quirk.
Hood / "High End"
Debut: Chapter 185 (Manga)
Quirks: Muscle Augmentation, Super Regeneration, Shoulder-Mounted Jets, Transforming Arms, Power, Storage
The first High-End Nomu introduced in the series. It's much more advanced than previous Nomu, as it's capable of rudimentary speech and basic thought. The League released it into Fukuoka, Hawks' hometown, to do battle with Endeavor.
- All Your Powers Combined: It has at least six Quirks, and infers it may be gaining more. Most Nomus can barely manage two.
- Blood Knight: It really wants to fight powerful people, quickly growing bored with whichever hero it's fixated on after managing to defeat them. It actually starts musing if there are stronger heroes after disabling Endeavor by damaging his left eye. Thankfully, the hero keeps his eye but there is a horrible scar.
- Body Horror: Its vertebrae are massive and poke through its skin, giving it a pronounced hunch. While its exposed brain is harder to see than other Nomus, it's still quite horrifying. Bits of its neck's muscle peak through it and its head seems to be INSIDE its neck, with only its eyes being visible.
- Enemy Summoner: Has a Quirk that allows it to either spawn weaker Nomus or stores them inside its body to be release later.
- Everyone Calls Him "Barkeep": It's referred to as High-End like it's his actual name. Later on it's shown that this is actually an appellation for all of the advanced Nomus, and it's proper name is "Hood".
- The Faceless: Its face is hidden, with only its eyes are visible. Even the reveal of what it looks like under it's hood counts as this since its entire head is an exposed brain with eyes and a massive fanged mouth that takes up the rest of the head's space.
- Flight: Is able to achieve this with a "Shoulder Jet" Quirk.
- Fluffy the Terrible: Daruma Ujiko calls him Hood-chan, despite being a deranged monster that caused mass destruction. Note the -chan honorific, which is used for things the speaker finds endearing, like babies or cute animals.
- Healing Factor: It possesses the "Super Regeneration" Quirk, like the U.S.J. Nomu. It's even able to survive after tearing off its own neck and head to dodge Endeavor's fire blast.
- History Repeats: It's the second Nomu to put a scar on a pro hero, after Aizawa got his head bashed into the pavement so many times by the U.S.J. Nomu it left a deep gash on his cheek.
- In the Hood: Its most notable feature is the "hood" formed from the skin of its neck being stretched up and over its head.
- It Can Think: Different than its predecessors, it's a sentient and thinking being, capable of speech and thought.
- Kill It with Fire: How it ultimately dies, thanks to Endeavor releasing his full power at point-blank range with no time for it to remove its head like before.
- Knight of Cerebus: Before it showed up, Nomus were generally expected to be mindless muscle, and the good guys learned to beat them. Then this one brutally injures the new number one pro hero and rips apart a whole side of his face and an eye.
- Life-or-Limb Decision: Tears its own neck and head off to avoid being incinerated by Endeavor's fire blast, trusting its "Super Regneration" Quirk to restore its body before Endeavor can recover. It works, but Endeavor doesn't give it a chance to do it again by making sure he's holding it by the head as he unleashes another blast.
- Lightning Bruiser: It's fast enough to nearly ambush Endeavor and Hawks, tough enough to take direct hits from Endeavor, and powerful enough to slice through a huge chunk of a high-rise building.
- Muscles Are Meaningful: Like Muscular, it has the "Muscle Augmentation" Quirk which can increase its physical strength.
- No Name Given: "High-End", what it's referred to throughout the Pro Hero Arc, is a moniker for his kin overall, not a distinctive label for him as an individual. It's just an indicator of what it is to other Nomus. It's later revealed that its name is "Hood".
- Oh, Crap!: When Endeavor and Hawks manage to catch it off guard with a combo-attack, the shock in his non-existent face is clear as day while he can only watch as Endeavor's flaming fists comes straight for it with no time to dodge.
- Shape Shifter Weapon: Has a Quirk that allows it to transform its arms to create powerful, elastic attacks.
- Spirited Competitor: It's fixated on finding a strong opponent. It unleashes its weaker Nomu brethren specifically to keep Hawks and other heroes from interfering with its one-on-one battle with Endeavor.
- Verbal Tic: Because its mind is just barely intact as the first Nomu to successfully retain a bit of thought, it has a very hard time speaking and its voice stammers up and repeats several words like a glitching computer.
- Villainous Breakdown: As the fight against Endeavor and Hawks goes against it, it becomes more and more unhinged. Eventually its fragile sanity seems to snap altogether, its stops speaking, and starts acting like a feral beast, including biting Endeavor.
- Wake-Up Call Boss: Serves as one to the heroes. Its intelligence, increased strength, and flight speed are a huge hindrance. The other problem is the fight with this Nomu demonstrates just how far Endeavor will have to go to fill All Might's shoes.
- Winged Humanoid: Due to possessing a "Shapeshifting Arm" Quirk, it can transform its arms into large wings to fly along with the "Shoulder Jet" Quirk.
- Wham Line: The quote above. The simple fact it can speak is shocking, since it shows that it is much more intelligent than any Nomu seen before it.
