League of Villains
Tenko Shimura — Tomura Shigaraki
- Adaptational Intelligence: A side-effect of Argonaut and his forces slaughtering the mooks at the USJ and being forced to dust the Nomu is that Tomura begins his Character Development early, in particular displaying more of a tactical mindset even before the fic's equivalent of Hosu. He likewise is much more wary of All For One's intentions for him following his meeting with Shinigami, and begins pursuing his own investigation while keeping All For One in the dark.
- Disabled in the Adaptation: He gets his finger shot off by Kaina, requiring he get a robotic replacement specifically attuned to his Quirk so he can use it in that hand again. He later has that same hand cut off in a fight with Shinigami.
- Grew Beyond Their Programming: Played with, considering he's human. Since the day All For One met him, he has been groomed into being someone who lives off The Power of Hate, an engine of destruction and "Symbol of Terror" with an indomitable will that can steal One For All back for him before then subsuming his personality and taking his body for himself. As a result of meeting Shinigami however, Tomura has begun developing intrinsic motivation, questioning the intentions of All For One and whether he truly has Tomura's best interests at heart, unknowingly loosening the grip of hatred that had taken hold over him for so long. This prompts All For One to consider him potentially compromised and begin looking for someone else to be his Body Backup Drive.
- Has a Type: Tomura ends up having a sexual awakening at the Hero Billboard Ranking event, specifically after he sees Izumi glaring at him with a look that says she will "Rip and Tear [his] Guts!’" He later lampshades how Out of Character it may seem for him, but seeing Izumi look at him like that made him both scared and horny, and while he won't go for Izumi since she's a Hero he wants to kill, he makes clear he finds people that angry and vicious to be sexually attractive.
Kurogiri
- Adaptation Personality Change: Kurogiri was effectively Tomura's glorified caretaker in canon, programmed to look after and advise him, the only hints of personality he displayed being the remnants of Oboro Shirakumo inside him. Here, Kurogiri is more akin to a Servile Snarker, and has interests outside of Tomura such as a love for H-games. He also appears to be unaware that he is a Nomu, as when Shinigami expresses familiarity with him, then uses her "Rot" Quirk on his "Warp Gate" and comments that she thought Dr. Garaki would have "patched out" that weakness, he thinks to himself in confusion about how he has no idea who she is, and questioning how could someone "patch out" a Quirk.
- Fake Memories: Kurogiri, being unaware he's a Nomu, thinks All For One actually hired him one day rather than created him.
- Spanner in the Works: His suspicions that All For One isn't truly looking out for Tomura's best interests causes him to slip a bug on Garaki, allowing him to overhear that the two of them and The Therapist were lying to Tomura about All For One's actual condition for the sake of manipulating him. This not only briefly causes him to break his programming, but makes clear to him that All For One is not to be trusted.
All For One
- Dark Lord on Life Support: Taken to a further extent here. All Might was very thorough in killing him here, not only destroying his head entirely, but burning the corpse. While he does have an Unexplained Recovery, it's regularly noted that he's stuck undergoing procedures from Garaki and the Therapist just to stabilize his health. When Tomura finally sees him, the sight isn't pretty. At least, that's what he wants Tomura to believe, as Kurogiri overhears him admit what Tomura saw wasn't his true condition, just something meant to make him hate Toshinori even more.
- Disabled in the Adaptation: While he was already a Dark Lord on Life Support in canon, he could still go into battle if he wore a special mask that helped him breath. Not so here. The damage Toshinori did to him left a lot less for Garaki to work with when reviving him, leaving him patched up and half-dead, requiring he remain in a Healing Vat until he can find a new body. Or at least, that's the cover story he's using to manipulate Tomura into hating All Might even more.
- Grand Theft Me: All For One retains his canon desire of turning Tomura into his Body Backup Drive so he can use Tomura's indomitable will to reclaim One For All. His plans face some issues however thanks to Shinigami causing Tomura to doubt All For One's intentions for him and begin acting independently. This forces All For One to start looking for a replacement for Tomura to take the body of instead.
- Unexplained Recovery: Toshinori was a lot more thorough with his attempt at killing All For One here. Not only did he crush the entirety of his head rather than just cave in his skull, he, Mirai, Gran Torino, and Kaina made sure to incinerate the body and scatter the ashes far apart for good measure. So it's to his shock and horror when Izumi tells him she thinks he's still alive upon realizing the first user of One For All and Tomura share a surname, questioning how he could have possibly survived that. Izumi's entirely right too, as he's The Man Behind the Man for the League of Villains, his condition being "critical" and requiring regular procedures from his doctors.
- Wrong Genre Savvy: All For One still considers himself the "Demon King" that all should rightly fear, and acts as if he is the ultimate threat to the narrative. This is in spite of the fact that Avalon has routinely managed to screw over his goals either directly or indirectly, Tomura is not under his thrall anymore, and he is barely a Normal Fish in a Tiny Pond when compared to the alien threats like the Heretics.
Dr. Kyudai Garaki
- Ambiguous Situation: It's unclear whether or not his misdiagnosing Momo Yaoyorozu as Quirkless was accidental. While it is possible he simply screwed up by using a faulty x-ray machine, its also possible he had lied about her being Quirkless upon learning of her "Creation" Quirk and thinking it would be a good fit for All For One, with the cover of her being diagnosed "Quirkless" to make it less noticeable when it was stolen. It's just he made the mistake of misdiagnosing the daughter of notorious Papa Wolf Kazuma "Yaoyorozu Dragon" Yaoyorozu, who was able to bring down the full might of the Yaoyorozu family the moment they found out he screwed up.
- Mad Scientist: He's the one responsible for making the Nomu, braindead humanoid abominations with multiple Quirks made from corpses. One of whom was his own grandson, Kaito, who was made into the Winged Nomu that attacked the Ryukyu agency.
- Nice Job Fixing It, Villain: A more minor example. His misdiagnosing of Momo Yaoyorozu as Quirkless prompted her family to launch a lawsuit against him, revealing dozens of other misdiagnoses over the years, leading to "Dr Tsubasa's" medical license being revoked and forcing him to discard that identity. This actually makes it easier for Izumi to pass off her suddenly having a Quirk as her just being a "late bloomer", since it would just seem like another misdiagnosis he made.
- What Happened to the Mouse?: Invoked regarding his identity "Dr. Tsubasa". Following a lawsuit from the Yaoyorozu family for misidentifying Momo as Quirkless that cost him his medical license and led to his temporary arrest, he discarded that identity, the public eye considering him and his family to have just vanished one day.
Martin Simonsen — The Therapist
- Creator Thumbprint: A telltale sign of his involvement is that his mutants will sport green veins, with the victims of his mutations, like Tsuyu and Ibara, developing similar veins.
- Eviler than Thou: He is an absolutely vile excuse for a human being, failing to see the issue other villainous individuals have with his methods. Plenty of other villains balk at the lengths and horrors he's willing to go with mutants, particularly when his actions land just short of genocide. His actions manage to disgust even Paxton, to the point that, when he caused the Long Island Massacre unprompted, Paxton was all too happy to use that as justification to finally try and kill him.
- The Faceless: He always wore a gasmask whenever anyone saw him, meaning no one knows what he actually looks like. This posed a problem when Dr. Paxton sent his HUNTER robot to kill him, as while the robot claimed it killed him, because no one knew what he actually looked like behind the mask, they had to take the robot at it's word since no one could identify which corpse was his, allowing him to successfully fake his death.
- The Man Behind the Man: The Therapist is responsible for numerous seemingly unrelated incidents around the world involving his mutants, all of which have caused immense death and nightmarish mutations. It was only after his involvement with the USJ attack and his creation of the Nomu did the WHA manage to piece together that he was responsible for so many incidents.
- Mind Rape: His Quirk is largely unknown even to Durandal, the most he knows being that he can somehow forcibly break the minds of those he uses it on, Durandal stating the few people who "survived" his Quirk shortly after took their own lives. The one person he's shown to use it on, Mirai, is left a Laughing Mad mess that can barely form a coherent sentence, which only annoys The Therapist since he had wanted to probe Mirai's mind, but instead decides to unload an entire submachine gun into his head just to shut him up.
- Nuclear Mutant: He's a biochemist by trade, and all of his creations have involved horrific mutations in some way, such as Mutator, Dr. Necro, and the Kremlin Bombing.
- One Degree Of Seperation: He's got his thumbs in a lot of pies, but one of the more notable ones is that he was responsible for the "Wildfire Protocol" being triggered at the original McCoy Medical Institute, and the events leading up to it saw him as a coworker of one Edmund Kirschbaum, son of Dr. Elize Kirschbaum, renowned German doctor and whose Quirk, "Cat Scan", is in Izumi's possession after Nine stole it and unloaded it on Izumi, her presence allowing the Vestiges to learn The Therapist's real name.
- Renegade Splinter Faction: He's a former member of Avalon Incorporated, having been brought on by the board of directors for the sake of forming a Bio-Weapons division, despite Paxton himself heavily opposing it. Following his causing the Long Island Massacre completely unprompted, Paxton ordered his HUNTER robot kill him and everyone in the Bio-Weapons division, The Therapist managing to escape somehow and causing many more catastrophes, before eventually joining All For One, bringing with him other former Avalon agents like "The Aviator" and "The Captain".
Stone Crusher
- Bait-and-Switch: When first introduced, he seems like just another of the "Children of Blood" loony fans, not helped by his being easily subdued by Bunny during her debut. When he returns, he makes clear he despises the "Children of Blood" for perverting Stain's message, and is an otherwise dangerous foe who only lost to Bunny because of her Quirk.
- Early-Bird Cameo: He first appears during Bunny's debut as a Pro-Hero, initially seeming like an ordinary member of the "Children of Blood" targeting Death Arms, only to turn up later as a new recruit for the League of Villains.
- Hero Killer: He's another follower of Stain and has killed several Pro-Heroes on his own. Unlike the "Children of Blood" however, the ones he killed were active Pro-Heroes, and he actually has the skill to back up his claims.
- Non-Indicative Name: As Tomura lampshades, "Stone Crusher" isn't exactly an accurate name for him. His Quirk has nothing to do with stones, it lets him summon four ethereal arms to fight with, nor does his body look like stone outside of his grey complexion.
- Suspiciously Similar Substitute: With Shuichi not becoming "Spinner" in favor of becoming the Intern for the Wild, Wild Pussycats, Stone Crusher fills his role in the League, being a Loony Fan of Stain initially introduced having issues with a female Pro-Hero.
Nine
- Even Evil Has Standards: Psychopathic villain he may be, he is not a pedophile, and cringes when the way he phrases going after Kazuma for his "Cell Activation" Quirk makes him come off as a child predator, desperately struggling in his head to find a phrasing that doesn't make him sound like one.
- Hoist by Their Own Petard: Nine ends up depowering himself of all but his original "Weather Manipulation" Quirk and the now-empty "All For One" copy due to his own actions. He attempts to unload "Cat Scan", a Quirk he considers useless to himself in his fight with Paxton, onto Izumi so that he can steal her Quirk, thinking it a simple Quirk with multiple aspects. Since it was actually "One For All" however and would not allow itself to be stolen, he instead simply gave Izumi "Cat Scan", and Durandal's Quirk Emulator being overcharged at the time caused him to end up giving his other eight Quirks to her with it.
- In Spite of a Nail: Despite initially having different Quirks in his copy of All For One, he still ends up gaining "Hydra", "Air Wall", and "Bullet Laser" after losing his original set to Izumi.
- Revenge Before Reason: He initially prioritizes retrieving his Quirks from Izumi, before shifting to wanting to kill Izumi over retreating with the rest of the League. This results in him being defeated by Izumi and nearly captured, only escaping thanks to Kurogiri.
- Sole Survivor: The only member of his original group to survive the fight with Paxton, as Mummy and Chimera were both killed by him.
Avalon Incorporated
In General
- Bunny-Ears Lawyer: Aside from Paxton Jr., the members of Avalon are all extremely quirky and borderline childish, spending their free time building nonsensical machines for fun, goofing around, etc. Paxton at the least has his eccentricities attributed to having gone to University in "Merchanicsburg", the home of the Heterodyne Family, and picked up their crazy in the process.
- Mad Scientist: A large portion of Avalon's enforcers acted as such, none more so than their leader, Dr. Paxton. Dr. Paxton favoring robotics and psychology, "The Therapist" favoring bio-chemistry, and "The Mechanist" favoring robotics and cybernetics.
- Spell My Name with a "The": Many of the members of Avalon went by a variety of titles including "The" in them: "The Mechanist", "The Writer", "The Therapist", "The Aviator", "The Captain", "The Band", etc.
- Villain Protagonist: Much like the League of Villains, the members of Avalon frequently have their own perspectives shown and get enough fleshing out to be major characters in their own right, chief among them being Paxton and Argonaut.
- Villainous Friendship: The forces of Avalon are shown to have a good sense of comradery amidst each other once they reunite, aided by Paxton acting as a legitimate mental health expert for each of them. The only exceptions being Argonaut and "The Mechanist", the former hating the later, and "The Therapist", who left Avalon on bad terms with Paxton, namely his actions disgusting even Paxton and leading to Paxton wanting him dead, hence his working for the League of Villains rather than rejoining Avalon.
Dr. Paxton Frederick Jones
- Affably Evil: Despite being a megalomaniacal Mad Scientist, Dr. Paxton is shown to be rather polite and cordial at times, especially after The Reveal he's also Dr. Isa, as he makes clear that not all of his patients were him trying to recruit people to his cause, but just as many were him trying to genuinely help people, Izumi being a standout example, as before she discovered Durandal, he only saw her as a suicidal teenage girl that needed help.
- Ambiguous Situation: No one knows what his Quirk actually is. From what Izumi could find online, his Quirk is considered the second biggest mystery out there, short of people wondering what All Might's Quirk is, as no one has ever actually seen him use it or explain it. For awhile, it seemed to be a case of Dramatic Irony since his identity of "Dr. Isa Tsuneyo" was stated to have the Quirk "Inertial Dampening", suggesting that was his actual Quirk. Izumi however eventually remembers how she really met Dr. Isa, and that the entirety of the version she believed happened, his "Quirk" included, was nothing but a lie, Dr. Isa instead having the ability to bring Izumi back to life and hypnotize her into believing his cover story. Paxton himself reveals in his fight with Nine that this is his actual Quirk, but that using it takes a year off his lifespan, and it has to be applied within an hour of the death occurring.
- Combo Platter Powers: He manages to perfect the Quirk Emulator for himself, installing it in his spine and using it to fight Nine. The perfected version can copy the Quirk of anyone with an Emitter Quirk that he touches, except for those connected to Stockpile Quirks like All For One.
- Even Evil Has Standards: Paxton may have been a horrific villain responsible for the collapse of multiple nations, but he had a lot of standards when it came to both his beliefs and his rules of engagement.
- He was a large advocate for mental health, ensuring all of his subordinates received proper mental care personally, and creating several robots to act as emotional support companions and therapy robots. It's because of this that Izumi is willing to keep Durandal when she, Inko, and Toshinori find him, figuring out he has programming for aiding in mental health and feeling he'd be a fitting substitute for the emotional support animal Dr. Isa wanted her to get, helped by the fact that Durandal was locked to Izumi's biometric data, meaning he couldn't disobey her even if he wanted to, and absolutely hates Paxton himself.
- While he did indeed wage war on multiple nations with his robots, he knows what he is, and admits not even he would trust him. This causes him to loathe those who take things too far, or try to hide behind delusions.
- The actions of "The Therapist" disgusted even him, the nuclear mutants he created and biological warfare he engaged in causing nothing but endless slaughters. It's to this end he had the Bio-Weapons division dissolved following the Long Island massacre, and ordered everyone in it killed by his HUNTER robot and all of their research destroyed, so as to make sure any knowledge of the chemical The Therapist made died with them.
- The Heroic Public Safety Commission disgusts him entirely, to the point he considers them Eviler than Thou, a notion META2012 confirms is entirely accurate
. A large part of it has to do with them, mainly their president, being willing to go to any lows they can to try and maintain their power, including using Child Soldiers and Engineered Heroics, all while hiding behind the façade of their actions being "for the good of Japan". Something he only reaffirms when he learns they revived him so he could make them a Quirk Emulator, and yet still tried claiming the moral high ground, Paxton genuinely believing them to be unbelievably stupid or flat out insane for not letting him stay dead.Paxton: I do have standards, woman. But from where I'm sitting, I don’t suppose you do. You care more about your personal reputation than protecting the lives of the civilians your heroes are supposed to protect, and creating environments to deliberately create villains for the heroes to fight.HPSC President: Of course you’d fail to understand. Everything we’ve done is for the betterment of Japan!Paxton: We can argue all day about this, and you'll always be in the wrong.
- Expy: Dr. Paxton Frederick Jones is described as the unholy combination of Dr. Ivo "The Eggman" Robotnik from Sonic the Hedgehog and Senator Steven Armstrong from Metal Gear Rising: Revengeance, with elements of Dr. Albert Wily from Mega Man (Classic).
- Eye Scream: Paxton lost his eyes to one of his own experiments shortly before his location was revealed to the US. The experiment in question? Nezu. The injuries Nezu caused left Paxton with severe scar tissue, and necessitated he replace his eyes with camera mounts, with which he uses either camera lenses when acting as himself, or false eyes when acting as "Dr. Isa Tsuneyo".
- Faking the Dead: For eleven years, the world has believed Dr. Paxton Frederick Jones died at the end of the Avalon War. After his robots and several of his old associates, including the Hero Killer Argonaut, show up at the USJ though, Nezu realizes that he's still alive. What's more, he was Hidden in Plain Sight, living incognito as Dr. Isa Tsuneyo, Izumi's very own therapist and the one who stopped her from committing suicide. Paxton proceeds to fake his death again by making everyone believe Dr. Isa was killed as he prepares to move towards Phase 2.
- Fan-Created Offspring: It's all but said that his grandfather, and the original creator of the Quirk Emulator that he would later finish, was Dr. Pietro Polendina from RWBY.
- Hated by All: Downplayed. Outside of Avalon Enterprises though, most people in the world hate Paxton, and with good reason considering the amount of death and destruction he's caused, with even people normally averse to killing making an exception for him. It's the point that Izumi, Katsuki, Ochaco, Rumi, and Durandal can all actually agree on the idea of him needing to painfully die via chainsaw enema, and at times having A Truce While We Gawk with the League of Villains just to watch Nine try and kill Paxton.
- Hidden Depths: At one time, he did have more idealistic leanings and willingly followed someone he considered his predecessor, even saying he would have journeyed with them to the edge of the solar system. But then something happened involving "human greed", and he ended up going on to form Avalon Incorporated.
- Laughably Evil: When he actually takes the battlefield himself, he proves to be this. Throughout his fight with Nine, he makes various pop culture references, memes, and snarky remarks, treating the fight like he was playing a video game more than anything. At one point he actually flips off Nine, only to then fire a laser beam from said finger while its still flipping him off.
- A Lighter Shade of Black: Despite his horrific actions and causing the Avalon War, he still is nowhere near as bad as either All For One, the Heroic Public Safety Commission, or the Heretics. Not only does he have plenty of standards and has the capacity to be kind as his treatment of Izumi can attest, he isn't as evil, delusional, or vile, as the other three, all of whom have shown to care little about anything other than themselves and maintaining their power, even at the expense of everyone around them. If Paxton is a "Villain", they are the "monsters".
- Luke, I Might Be Your Father: Defied. After he rants about Mei being able to make DNA-encoded armor using Carusaurum much faster than he ever could, Jin asks if it's possible Mei could be his daughter and she inherited his intellect, something that would fall in line with Mei never having known her dad and believing he's dead, and Paxton's propensity for false identities and faking their deaths. Paxton however quickly stomps out that idea, revealing that while he did sleep with one of three women with the name "Hatsume" in his brief time in Japan, not only did he wear protection when he did so, he's also sterile, meaning she can't be born from him.
- Off with His Head!: Apostle, being a Death Dagger, decides to decapitate his comatose body rather than risk him escaping, then orders his body burnt to ashes and the ashes scattered as far as possible just to ensure he's dead this time. This did actually kill him... but only for a half hour, as the HPSC managed to revive him so they could try and get him to make them a Quirk Emulator.
- Pet the Dog: His relationship with Izumi prior to her finding Durandal was this in a nutshell. He had no plans for her at the time, he was just passing by when he saw her Driven to Suicide and managed to save her, then took her on as his patient, just seeing a girl that needed help. Even the reveal of how they really met doesn't change this, as he came across her corpse after her suicide, but still chose to revive her out of no benefit to himself. And while he did use Hypnotic Eyes on her, it's made clear he didn't like having to do so but needed her to calm down, and he only uses them to make her believe she never actually died and out of worry she'll try to take her life again.
- Skewed Priorities: He considers himself a scientist first and foremost, so when Izumi suddenly gains Nine's Quirks and enters a trance, he forgoes simply taking his leave in favor of trying to analyze the data now available to him. Even as Izumi is about to deliver the finishing blow to both him and Nine, he's more astounded by the ideas he's gaining from observing her, leading to his capture, brief death, and then imprisonment under the HPSC.
- Too Kinky to Torture: The HPSC's attempt at torturing him just ends up arousing him, to the point his near orgasmic moans the HPSC president mistakes for someone loudly watching porn, and Paxton is almost disappointed when it's ended early.
- Villain Takes an Interest: He ends up taking an interest in, and later frustration with, Mei after his spy in UA tells him that she managed to create DNA-encoded armor using Carusaurum, something that took him over a decade to figure out himself. While he recognizes that she's a Gadgeteer Genius, he is frustrated that she managed to achieve such a feat with such a rare metal in such a short amount of time. While Argonaut asks if they should kill her, he makes clear he only wants to keep an eye on her for now, but will ordered her killed if she ever manages to recreate a Quirk Emulator, later making clear only he should have the knowledge on how to build one, and would rather see it destroyed than let it fall into the wrong hands.
Grigoris Siderallis — Argonaut
- Actually a Doombot: Much to Durandal's frustration, none of the Argonaut's faced at the USJ were the real him. Two were clones made using Jin's "Double" Quirk, and one was a remote control drone modelled after the Terminator. The latter confuses Durandal just as much as it angers him, since such a tactic is more akin to the methods of "The Mechanist", who Argonaut infamously hates with a passion and wouldn't willingly work with, leading him to conclude someone else is responsible for their working together.
- Didn't Think This Through: His first immediate thought upon coming across a female robot in Paxton's lab was that it was a sexbot, and he proceeded to put his junk in it. As he later finds out, it was a breeding machine, and resulted in the creation of an opposite gender Mini-Me being born.
- Even Evil Has Standards: He's fully aware he's a psychopathic Hero Killer, and even calls himself a monster. For the most part, he doesn't really mind. After he accidentally ends up using a breeding machine thinking it was a sexbot and it ends up conceiving a daughter, he immediately decides it would be better if she was put up for adoption, not because he doesn't want her, but because he knows having him for a father would be horrible for her.
- Hero Killer: Argonaut is responsible for the deaths of hundreds of heroes worldwide. He doesn't kill for any higher purpose or reasoning, but solely for the enjoyment of killing. Very few have survived an encounter with him, as most die quickly when he sets his sights on them. Anan Kurose/Thirteen is added to his resume when he first invades the USJ, and Nejire would have joined her had Durandal not managed to heal her.
- Ironic Name: He is named after the famous group of Greek heroes, the crew of the Argo under Jason who, even at their worst, still performed many heroic acts, and served as the Ur-Example of the Super Team. Argonaut meanwhile is as unheroic as you can get, being a Hero Killer who kills just for the satisfaction of killing, has almost no low he won't stoop to, and regularly fights alone.
- Weaksauce Weakness: Argonaut's opinion on certain aspects of his Quirk, "Enhanced Reflexes". Argonaut's Quirk allows him to immediately dodge anything he is aware of such as gunfire, and is most useful in an open field, as the Quirk will automatically direct him towards the most effective means of survival, in said situation being the destruction of the threat. In more enclosed spaces however like a forest, his Quirk will override his conscious thoughts and force him to take cover, leaving him incapable of fighting back and put him at risk of anything his Quirk fails to recognize. He carries a pair of Quirk Suppression Bracelets to counteract this should it occur, but using them turns off his entire Quirk, leaving him just as vulnerable as anyone else.
Hilala
- Green-Skinned Space Babe: Aesthetically, as she possesses vibrant green skin, is very tall and muscular, and regularly dresses in Leia's slave outfit. She's fully human though, even if her Quirk would suggest otherwise. Played completely straight with the reveal she's actually an alien, her aesthetics, outfit included, being commonplace amidst her race, the Cardrians.
- I'm a Humanitarian: She's a maneater, and has devoured people to the bone via her swarm.
- The Man Behind the Man: Discussed and Played with. Durandal knows full well that Paxton was the brains and leader of Avalon, but is fully aware that Hilala was someone he had a unique relationship with, being someone with intellect to rival his. After learning about the existence of aliens however and that she's likely part of the "Cardrian" race and how they are leagues more technologically advanced than humanity, Durandal theorizes that she is the reason Avalon has access to so much advanced technology, having approached Paxton at some point and offered him access to her knowledge, allowing him to innovate it and establish Avalon.
- Royal "We": She refers to herself as such, implicitly of her being a living swarm of insects. This is later shown to be a trait her entire species, the "Cardrian", share.
- The Swarm: Her Quirk, "Swarm", allows her to divide herself into millions of microscopic insects, said insects capable of stripping her victims to the bone in a matter of seconds, all controlled via a Hive Mind. It's later revealed that's not actually a Quirk, but rather her natural biology as a "Cardrian", being a swarm of bugs who make up a single mind rather than the standard multiple minds forming a single Hive Mind.
Jin Bubaigawara — Twice
- Adaptational Heroism: Subverted. While he does receive help as a result of meeting Dr. Isa and in turn doesn't have the incentive to join the League of Villains, this just leaves him free for Isa's true identity, Dr. Paxton, to recruit him to Avalon instead.
- Amazon Chaser: He apparently is attracted to Hilala, as he ends up admitting during one of his contradictory moments that he wants her to crush his head with her thighs.
- Bunny-Ears Lawyer: He's mentally unstable and a cloudcuckoolander on a normal basis, with Argonaut even wondering why they recruited him in the first place. As Paxton points out though, "Double" is an extremely powerful and useful Quirk, and it's usefulness is well worth entertaining his eccentricities.
- Mood-Swinger: He retains his canon habit of immediately self-contradicting whatever he says, making him come across as one.
- Small Role, Big Impact: While he isn't actually present at Argonaut's invasion of the USJ, it was his "Double" Quirk that created the Argonaut clones, one of which was responsible for killing Anan/Thirteen.
- Unrelated in the Adaptation: Jin lacks any connection to the League of Villains or Himiko here as a result of receiving therapy from Dr. Isa, instead becoming an agent of Avalon Incorporated.
Tesla
- Ascended Extra: Tesla has a much bigger role here, thanks to his dad being an Avalon scientist. This makes it easy for Paxton to recruit him as a full time agent of Avalon, have him briefly infiltrate the League of Villains, and disable the temporal jammers at the USJ, leading to Argonaut's invasion.
- Only Sane Man: Amidst the members of the rebuilt Avalon, he's the only one without any notable eccentricities, and in turn tends to play the Straight Man to the others quirky behavior.
Tycho
- Just a Machine: Whereas Durandal is a fully sapient A.I. with a sense of identity on par with a humans, Tycho was built to be much less "human", it's voice described as cold and unempathetic, while acting more in the capacity of an assistant to Paxton who does as he's ordered.
- Kill and Replace: Discussed. Paxton's original plan for Izumi after seeing her during the UA Entrance Exam was to have Tycho eliminate and covertly replace Durandal, allowing Paxton another spy inside UA. Upon learning Izumi now had a Quirk however and mistakenly believing she's a spy for All For One, Paxton scrapped that plan so that AFO wouldn't learn he's alive still, but kept developing Tycho for other uses.
- Superior Successor: Tycho was built to be Durandal's superior in every way, including his Quirk Emulator being a perfected version of the prototype Durandal took.
The Hacker
- Accidental Pervert: His escape method was to teleport to the closest Avalon member possible, which just so happened to be Hilala... as she was in the middle of a shower. She throws him through a door as a result.
- Adaptational Job Change: In canon, he was a mercenary under Wolfram working to steal the Quirk Amplifier to sell to the highest bidder. Here, he's an ex-Avalon scientist who signed on to work with Wolfram to cross "hacking into the I-Island security systems" off his bucket list, and quickly rejoins Avalon when given the chance.
- Ascended Extra: Gone from a nameless grunt in his movie of origin to the only member of Wolfram's group to escape I-Island, rejoining Avalon in the process.
- Contrived Coincidence: He manages to hack into and steal backup data on the I-Island servers right as Hilala, Tesla, and Jin had come to I-Island to do the same thing, sparing them the effort when he meets up with them.
- Hired Guns: Unlike the rest of Wolfram's group, he's not an ex-RAFT agent, but instead an ex-Avalon hacker hired to break into I-Islands security, taking the job to knock it off his bucket list.
SPOILER CHARACTER
Paxton Frederick Jones Jr.
- Clones Are People, Too: Played with since he makes clear he's not truly a clone. While he was created to serve as a backup incase something were to happen to Paxton Sr., he implores the rest of Avalon to treat him as his own person, rather than just a younger Paxton.
- Crazy-Prepared: The result of Paxton Sr. being such. Paxton decided, in the event anything ever happened to him while rebuilding Avalon, he'd need someone just like himself to keep it running. So he decided to create a Mini-Me to act in his stead.
- Mini-Me: Explicitly namedropped as one in reference to Austin Powers. Jr. is essentially Paxton when he was sixteen years old, having all of his memories, but their experiences diverging from the point of memory implantation onward. He elaborates however that, physically, he is not a clone, describing himself as more akin to a Hollow Child, making him more akin to an android copy.
- Surrounded by Idiots: "Children" more accurately, but he questions how so many of Avalon's forces can be so childish off the clock, expressing exasperation at their antics like Argonaut mistaking the robot that gave birth to him for a sexbot. He seems to not realize his father is just as insane and goofy as the rest of them.
Children of Blood
In General
- Big Bad Wannabe: The "Children of Blood", more specifically their leader the "Scion of Blood", like to see themselves as the "disciples" of the Hero Killer Stain destined to bring an end to the "false heroes", and sought to use the League of Villains as a means to an end for their planned attack on multiple Pro-Hero agencies. Not only are they all amateurs though, their only confirmed victims are those that they either caught off guard with sheer numbers, or retired Pro-Heroes Stain had already hospitalized but chose to spare, most of them barely knowing how to wield their weapons. So when they launch their attack, it lasts all of ten minutes before it ends, and while they caused some destruction of public property thanks to crashing trucks into agencies and being loaned Nomu by the League, the only actual fatalities to occur were their own members. Didn't help that their "plan" was to go Leeroy Jenkins on each agency they targeted, one of their targets was "Apostle", a Pro-Hero with close ties to the JSDF, whose agency is right next door to a JSDF base, and is one of Japan's certified Death Daggers with no issue killing them, and the Scion went after Endeavor who, 0% Approval Rating aside, had once been the Number 2 ranked Pro-Hero solely due to his work ethic. Needless to say, their asses were easily handed to them.Seriously, you don’t attack a Death Dagger and expect to live.
- Cult of Personality: They're a group of Stain fanatics numbering over 400 who have fully ascribed to his dogma of corrupt heroes, but take it further than even he ever did. For one thing, Stain only believed in killing the genuinely corrupt, only crippling those he saw as having the potential to atone for what they did. His "followers" however believe that all heroes are corrupt, and kill not only the innocent, but track down and kill the ones he spared. Their leader, the "Scion of Blood", believes Stain didn't take his crusade far enough and seeks to organize their forces into a united front, using the League of Villains as a means to an end, his overall attitude heavily reminiscent of a cult leader. Chizome, for his part, doesn't approve of their actions, feeling they merely pervert his message, and upon being made aware of how everyone thinks they are genuinely his followers, he laments not taking care of them himself.
- Hero Killer: They're a Cult of Personality devoted to Stain, with even less scruples than him, believing there are no true heroes. And while Stain had spared certain heroes thinking they could change for the better once they healed, these fanatics instead proceed to track down the ones he spared and "finish the job". It's later revealed their victims largely comprised of either those they caught off guard with sheer numbers, or already retired Heroes.
- Zerg Rush: Downplayed. What they lack in skills they make up for in sheer numbers. The majority of the members are amateurish, demonstrating poor grips of their weapons and poor trigger discipline. However, as Tomura finds out after he has Kurogiri assemble all the members from across Japan, their membership totals at 428, making them a small army that could attack and overwhelm people through their sheer size. Their other weakness however, their overzealousness, leads them to also be poor planners and acting like Leeroy Jenkins, meaning they're easily taken out by the more experienced Pro-Heroes, and are only successful at surprise attacks.
The Scion of Blood
- Loony Fan: He claims to have been Stain's disciple and constantly rants about Stain's magnificence. As Stain himself however never took any disciples, he's more accurately just another of Stain's psychotic fanboys. It doesn't help that, as Tomura finds out after first meeting him, not only does he never blink due his Quirk, he won't shut up, going on a ten minute long speech when Tomura asked him a simple yes or no question. As Tomura later finds out after doing some research on him, he was legitimately insane, having been locked in a mental institution before becoming obsessed with Stain and breaking out, and even before then had been a delusional and inadequate instructor at Shiketsu who cared more about defeating his students so they'd consider him the "best trainer they ever had". Learning all this makes Tomura happy they didn't waste any actual resources supporting him.
- Suspiciously Similar Substitute: With Dabi/Toya Todoroki being an Adaptational Nice Guy and the original Todoroki subplot being excised, the "Scion" instead fulfills his canon role, being a fanatical and zealous follower of the Hero Killer Stain who takes their belief in "false heroes" even further by claiming there are no true heroes, and fully intends on using the League of Villains as a means to an end for fulfilling Stain's "mission".
The Master of Blood: Scourge
- Body Horror: While his Quirk is unknown, what he does to his victims has lead to the belief he has a bone or muscle manipulation Quirk, his victims found with their bodies contorted in unnatural ways, described as "bent" in some cases.
- Superior Successor: Following the Scion's defeat and most of the groups arrest, "Scourge" appeared, recruiting the remaining members and militarizing them, making them far more competent than the original group. It helped that Scourge alone had already destroyed three Hero Agencies, killing everyone in them, Heroes and Staff alike.
Heroic Public Safety Commission
RAFT
In General
- 0% Approval Rating: Absolutely no one likes the organization, due to their corruption, their practice of Quirk marriages, and the fact that they pretend to be heroes of the Avalon war despite not doing much other than protecting a few power plants. The fact that they work with the equally corrupt HPSC doesn't help matters either.
- An Offer You Can't Refuse: They seem to believe in this, as if someone refuses to work with them no matter what they offer, they are not above killing them via bombing, choosing to get rid of them if they can't get them under control (as shown with the attempted assassination of Endeavor).
- Chosen Conception Partner: They practice Quirk marriages, effectively turning their partners into breeding slaves to create stronger Quirks.
- Hated by All: It goes without saying that no one likes them.
Other Villains
Kai Chisaki — Overhaul
- Big Bad Wannabe: He views himself as the man who will bring the yakuza back to prominence with his Quirk-destroying bullets, and is built up as an enemy that the heroes will need to face one day. Instead he gets unceremoniously Killed Offscreen the day before the heroes got to him.
- Death by Adaptation: Unlike in canon, here he is Killed Offscreen by a Sematick for unknown reasons.
- Hated by All: Anyone not a part of his yakuza organization positively hates his guts for what he did to Eri. In fact, it became a Running Gag where once people were informed about how he tore out Eri's vocal cords, they expressed the desire to kill him in various gruesome ways.
- Killed Offscreen: He gets killed by an unknown Sematick shortly after his men failed their ambush attempt to get Eri back.
- Ludicrous Gibs: All that's left of him by the time the heroes got to him is a bloody mess that was once a person.
- Would Hurt a Child: Considering he was willing to torture Eri to harvest her DNA for his Quirk-destroying bullets, in addition to cutting out her vocal cords so he wouldn't hear her crying anymore, he's more than willing to hurt kids. He even planned for his men to kill UA students to get Eri back.
