- Blue and Orange Morality: Toga doesnt see anything wrong with her actions because its how she expresses love, which she considers undefinable.
- Body Horror: She manages to get to collect enough of Peter's blood off of Stain's weapons for her to transform into him. But its radioactive properties wreak havoc with her Quirk, and her face starts to melt off in the process.
- Cute and Psycho: She's a cute-looking high school girl who happens to be a serial killer obsessed with blood and consuming it to steal the identities of others.
- Depraved Bisexual: Gender doesn't matter when it comes to her affections: only how much and how frequently her newest crush is bleeding.

Chizome Akagaro - Stain
Debut: Issue #6: Power and Responsibility
The infamous "Hero Killer" who targets Heroes he deems to be "Fakes" in hopes of creating a world where there are only purely selfless heroes like All Might. His Quirk, "Bloodcurdle", allows him to paralyze people by consuming their blood, with the amount of time spent paralyzed varying based on blood type.
- '90s Anti-Hero: He sees himself as one, culling the "fake" Heroes so that "real" Heroes like All Might would take their place. The narration even lampshades the fact, given his pouch and blade-filled aesthetic, edgy name, and a power activated by consuming blood.
- Adaptational Early Appearance: He appears as early as Issue 6, a day before Izuku takes the U.A. Entrance Exam. In the manga, he doesn't appear in-person until after the Sports Festival.
- Adaptational Villainy: He's somehow worse than his canon counterpart since he's clearly more deranged and is even willing to kill on incredibly flimsy reasoning. His reason for attacking Peter is because he believes Peter's a vigilante who patterns himself after Spider-Man, which means he's a selfish fake who can't own up to his actions. Once he learns Peter is Spider-Man, he goes absolutely foaming at the mouth crazy trying to kill him.
- Ax-Crazy: He's obsessed with culling Heroes he deems to be "Fakes" and wants to murder as many as he can so more can be like All Might.
- Bad Powers, Bad People: An Ax-Crazy murderer suffering from Black and White Insanity has a Quirk that lets him paralyze others by licking their blood.
- Berserk Button:
- Hypocrisy, or more specifically, anyone who falls under a shade of gray outside of Black and White Morality. He dismisses Mount Lady genuine feelings of remorse for being unable to stop the Prowler as an attempt to save face (albeit, she was trying to improve her image) and throws a knife at the TV out of disgust. He proceeds to stomp and crush on the miniature TV for a while until he calms down.
- Spider-Man is an especially hot subject for him, as Stain blames him for normalizing the idea of a "relatable" Hero who might put his own needs before others when compared to the boy scouts embodied by previous "fictional" characters like Superman and Captain America. As such, he pins the current Hero system on Spider-Man, which spurs him to go after Peter. When he finds out that Peter is the actual Spider-Man, Stain goes ballistic and screams for him to die while blaming the world on him.
- Black and White Insanity: Stain is a moral objectivist, believing that there are only pure good and pure evil and that any semblance of grey needs to be culled. This is emphasized by the Mr. A comics lying around his apartment.
- Blood Lust: He licks up the blood of others in order to activate his Quirk. His entire fighting style and use of swords and daggers are designed to make this easier for him.
- Blood Magic: His Quirk requires him to consume blood in order to activate it.
- Bond Villain Stupidity: After he manages to paralyze Peter, Stain goes on a Motive Rant on why he kills Heroes and why he hates Spider-Man especially. Unbeknownst to him, Peter's radioactive blood let him shrug off the effects of Stain's Quirk faster, leading to a surprise sucker punch before subjecting Stain to a No-Holds-Barred Beatdown.
- Close-Range Combatant: His only ranged attacks are throwing his knives at people, as he needs to get in close to draw people's blood and lick it off his blade.
- Combat Pragmatism: His M.O. involves him ambushing unsuspecting victims and taking their blood before executing them while they're paralyzed and helpless.
- Costume Porn: The story goes into meticulous detail about his costume and as shown by the picture above, it's far more complex than most characters' outfits in the story.
- Determinator: He will not give up in his quest to purge the world of "fakers" no matter what. Even after getting his jaw fractured, the bones in his shoulder dislocated, and being pinned to a wall by webbing, he still tries to make wild swings at Peter with his free hand.
- Didn't See That Coming: He has Peter at his mercy after managing to lick his blood. Unfortunately for him, his Quirk wore off far more quickly than expected thanks to Peter's radioactive blood.
- Dramatic Irony: He mentions that he plans to keep an eye on Izuku to make sure his heroic ideals aren't "corrupted". Little does Stain know that Izuku has already decided to take up the mantle of Spider-Man, who Stain despises the most.
- Dual Wielding: He often takes a sword and a dagger out at the same time.
- Evil Counterpart: Peter unfavourably compares him to the Punisher. There's the crusade, the ultra-violence and the black-and-white morality, but at least Frank never claimed he was killing people for noble reasons instead of his own self-satisfaction.
- Glowing Eyes of Doom: Stain's red eyes seem to glow in the dark.
- Hero Killer: As shown by his title, he's killed and maimed dozens of Heroes on his own. He also manages to nearly kill Peter, a veteran superhero in his own right.
- Despite one of his Berserk Buttons being a hypocrite, he himself is a hypocrite since he despises Heroes who act in their own self-interest and his murderous crusade is ultimately born from serving his own personal gratification.
- On a meta-level he's also a fan of Steve Ditko's Mr. A, highlighting his obsessive belief in its themes of Objectivism. However he violently hates Spider-Man for being a down-to-earth Classical Antihero instead of the sterling boy scout heroes of the past. Both were creations of Steve Ditko.
- Insane Troll Logic: One of the reasons he thinks Peter is a "faker" is because he dodged a trash can, believing that a true hero would've just taken the hit because "What if there was a civilian who just used the side exit for a quick smoke?"
- Loony Fan: He's a crazed fan of All Might, attacking, maiming, and murdering Heroes he believes failed to live up to All Might's standard of heroism.
- Made of Iron: He's amazingly tough despite not having a Quirk related to his durability, managing to fight Peter on even ground. This is what convinces Peter to finally cut loose and whale on Stain, who could actually take one of his hits and not die. By the end, Stain is still alive after getting multiple bones broken, his jaw dislocated, his cheek torn open, and having his wrist crushed by Peter.
- Knife Nut: He carries knives constantly, including one he uses to destroy a small television set.
- Oh, Crap!: He finally shows panic when he realizes that he's going to be put in jail by the one Hero he despises the most: Spider-Man.
- Reverse Grip: He makes gratuitous use of this while fighting Peter.
- Serial Killer: Stain targets any Hero he deems a "Fake", meaning anyone who isn't as selfless and altruistic as All Might. Given how lofty that goal is, it's rare for Stain to approve of anyone.
- Sleeves Are for Wimps: His outfit doesn't have sleeves and he nearly manages to kill Peter.
- Villainous Breakdown: He completely loses his cool after getting his jaw broken. Shortly after accepting Stain's criticisms, Peter reveals that he's the real Spider-Man and not some imitator before giving him a "The Reason You Suck" Speech about Stain's short-sighted motives. As Peter moves in to knock him out, Stain starts flipping his shit about how only All Might is allowed to defeat him before Peter shuts him up. Unlike his badass final stand in canon, this Stain is more of a pathetic rabid dog.
- Villain Has a Point: Downplayed. Stain rants and raves about how Heroes aren't as selfless as they used to be. He's justified by Mirko and Mount Lady bickering over who gets credit for beating the Rhino and picks apart Peter's own faults. By the end of their fight, Peter admits that Stain is right, but that doesn't justify killing less straightforwardly good Heroes as they have families and are still out there helping people.
- Villain Takes an Interest: He's interested in Izuku's selflessness and willingness to risk his own life for an (apparently) complete stranger after seeing the incident unfold on TV. He takes note of Izuku and declares that he'll monitor him to prevent his "corruption".
- What the Hell, Hero?: He calls Peter out on not stopping to think about the people who would get caught in the crossfire when he took to the streets to flee from Prowler.
- You Will Be Spared: He decides that Izuku won't be on his hit list after watching him run at the Prowler on television. Peter on the other hand...
Rocket Racer Gang
Debut: Issue #6: Power and Responsibility
A gang of aspiring Villains riding around on rocket-powered vehicles. They're among the many upshot Villains who are taking inspiration from Marvel rogues with the tech they acquired from Mysterio. They're tearing up the streets of Musutafu while Izuku is busy training to get into U.A.
- Cool Board: The leader, Number One, has a rocket-powered skateboard.
- Fingore: Number One's hand is left a broken and bloody mess after Peter tricks him into ramming it into a concrete wall.
- Hoist by His Own Petard: Number One's reckless use of the rocket-powered equipment he used to assault and steal from others ends up horribly mangling his hand when he punches a concrete wall at 60 miles an hour.
- Laser-Guided Karma: Number One gloats when he brutally punches out a police officer while riding his rocket-powered skateboard. While he's initially able to get the drop on Peter when he was blinded by One's visor, Peter manages to goad One into trying to Rocket Punch him while Peter stood next to a wall, only to jump away at the last second, letting Newton's Third Law mangle the villain's hand.
- Legacy Character: They're the unofficial successors to the original Rocket Racer, who began as a D-list supervillain before becoming a D-list superhero and retiring altogether.
- Mythology Gag: They hide their identities by wearing masks of popular Heroes, including Ingenium, All Might, Endeavor, and Spider-Man. Then Peter arrives to stop them while quipping, "You lost weight, All Might!"
- Red Is Violent: A team of six red-wearing hellions who happily wreak havoc in Musutafu, causing grievous injury and looting whoever they can. Himiko is this epitome of this, slashing random people for no reason just to see their blood. The scooter-riding members also have rocket launchers built into their gear that fragment into shrapnel, heavily injuring Manual and several bystanders despite his best efforts.
- Rocket Punch: Invoked. Number One has rockets on his gloves that he uses to quickly close the distance on an officer and punch him hard enough to rip open the skin on his face and knock out several teeth. He shouts, "Aw yeah! Hows that for a Rocket Punch?!" while speeding away.
- Rollerblade Good: Himiko and two other guys roll around on four-wheeled roller skates.
- Stuffed into a Trashcan: Peter tosses the Gang Orca Rocket Racer into a dumpster with a web before tying down the lid with another web.
- Unskilled, but Strong: Their equipment makes them a menace, but none of them are especially skilled. Number One is shaking his hand after punching Peter several times, tipping Peter off to the Rocket Racer's lack of Super Toughness and his inexperience in a fight.
Debut: Issue #8: Super Hero School
A group of Villains who used the equipment of Abner Jenkins. They're brutally murdered by the Enforcers after failing to pay their dues.
- Cruel and Unusual Death: Clash kills one of them by emitting a powerful noise that made him bleed from his eyes, nose, and ears. Vulture kills another one by somehow riddling his body with holes and obliterating half of his face.
- Powered Armor: They used a version of the armor used by the original Beetle, which grants superhuman strength, speed, and durability.
- We Hardly Knew Ye: Offed as soon as they were introduced to demonstrate the lethality of the Enforcers.
