The world of My Hero Academia: Vigilantes adds depth to many iconic villains, casting a new light on their origin stories and motivations. With Stain’s return as Stendhal, the door is wide open for other fierce antagonists to make their presence known in the gritty streets of Vigilantes. Fans are eager to see which foes might appear and threaten the vigilantes led by Koichi Haimawari.
Many villains featured in the main series have complex backgrounds that fit well with the earlier timeline of Vigilantes. This list explores fifteen characters whose backstories or criminal activities could drive gripping story arcs, bring tension into street-level battles, or unravel dark secrets within society’s underbelly.
15 Twice’s Early Struggles with Identity
Twice is a tragic villain whose issues with identity and loneliness made him one of the most human characters in the League of Villains. Before aligning with Shigaraki, he was already struggling to find his place in a world where he could never be sure of his own reality.
In a Vigilantes timeline, Twice’s psychological challenges and criminal tendencies could lead to unique run-ins with Koichi and his allies. His Quirk, which lets him duplicate himself and others, would be as unpredictable as his mental state. An encounter with the vigilantes could showcase his paranoia and confusion, revealing how dangerous an unstable criminal can be.
Twice’s early period before joining the League could bring emotional depth to the series. Fans could see just how isolating his life was, constantly questioning his very existence and often wishing for a sense of belonging. This would deepen the impact of his later, more notorious appearances.
His presence in Vigilantes might also highlight the way the world overlooks people like him, causing them to spiral into villainy. Twice represents those left on the margins and how society’s neglect can lead them down the darkest paths even before major events shake the hero world.
14 Moonfish’s Unchecked Bloodlust
Moonfish, remembered for his horrifying appearance and insatiable appetite for flesh, is one of the creepiest villains in My Hero Academia. His Blade-Tooth Quirk and violent tendencies made him a nightmare even among criminals.
Bringing Moonfish into Vigilantes would offer street-level horror unlike any other. His attacks on random civilians, motivated by uncontrollable urges, could shock both vigilantes and pro heroes alike. Moonfish embodies the threat of criminal insanity lurking in the shadows.
It would be fascinating to see Koichi’s squad confronted by such brutal villainy, forcing them to rethink their methods and safety. Moonfish’s rampages could be turning points in the story, showing the grim reality the vigilantes face outside the limelight of hero society.
Events featuring Moonfish could also show how even lesser-known villains drive fear into communities. Instead of grand schemes, his unpredictable violence brings home the constant danger hanging over everyday citizens in a world filled with powerful, unstable quirks.
13 Rappa’s Street Fights
Rappa, a brutal enforcer from the Shie Hassaikai, lives for combat and has little patience for anything else. His straightforward love of fighting makes him a unique force among the criminal element.
In the Vigilantes timeline, Rappa’s role as a street fighter could put him in direct conflict with Koichi’s group. His simple philosophy – to chase the thrill of battle and prove his strength – would clash with the ideals of street-level heroes, generating intense action scenes.
His willingness to challenge any opponent could also draw various vigilantes and villains into his orbit, sparking rivalries and tense alliances. Whether Koichi would try to reason with him or be forced to flee could form the heart of a memorable arc.
Adding Rappa’s chaotic approach to the mix would show the unpredictable ecosystem of crime outside the main story’s organized villain factions. He thrives on mayhem, giving a realistic glimpse of the raw violence on city streets before order breaks down even further in My Hero Academia’s main events.
If Rappa fought alongside or against the vigilantes, fans would get to see whether strength alone can decide fate in a world shaped by quirks and ambition.
12 Giran’s Underground Deals
Giran is the League of Villains’ broker – more businessman than brawler, but no less important in the criminal world. He helps connect aspiring villains with resources, safehouses, and each other.
Picking up in the Vigilantes period, Giran could be shown in the thick of recruitment and negotiation, scouting fresh talent or shuffling illegal weapons and drugs. His interactions with street-level criminals and vigilantes would reveal the invisible networks supporting villainy long before the events at UA High.
Giran’s scenes might delve into the economics of villain activity – how criminal underworlds function in a society preoccupied with flashier threats. Vigilantes trying to trace local crimes back to their source would inevitably bump up against Giran’s schemes.
The tension between the rules of heroes and the shifting rules of criminals could make Giran a recurring minor antagonist. His ability to remain hidden in plain sight, always with plausible deniability, would keep him out of the direct line of fire while pulling the strings behind the scenes.
11 Magne’s Quirk in Action
Magne stood out in the League of Villains, not just for her magnetic personality, but for her distinctive Magnetism Quirk. This power allowed her to manipulate the polarity of others, creating unpredictable combat situations.
Vigilantes could make good use of Magne’s abilities during robberies or criminal operations, showing how a strategic Quirk brings new challenges for Koichi’s squad. Her arc could include moments of camaraderie and tension with other villains, and more room for her character to grow than in the main anime.
More than just battles, Magne’s story could spotlight issues of acceptance in both the criminal and hero communities. Bringing her personality and struggles forward would round out the cast and touch on how people with non-traditional powers or identities find their way in a judgmental world.
Vigilantes would benefit from having to think creatively when facing a villain who doesn’t rely purely on violence. Magne’s emotional moments in Vigilantes could leave a direct and powerful impact on viewers and the vigilante team alike.
10 Gentle Criminal’s Solo Schemes
Gentle Criminal’s early attempts to make a name with online stunts and minor crimes put him squarely in the spotlight as an unconventional antagonist. His Elasticity Quirk allows for inventive criminal activities, but his goals focus more on fame than destruction.
Before meeting La Brava, Gentle’s solo career could intersect with the Vigilantes, either as a rival or as a wildcard who unintentionally creates chaos for both sides. His passion for being recognized would collide with the need to avoid capture, driving tense chases through city streets.
Showcasing Gentle’s willingness to risk it all for a viral moment, the series could deliver some of the most entertaining sequences while still capturing the sadness behind his need to be seen. The vigilantes would face a criminal who is not evil, just determined to be unforgettable.
His escapades could provide a lighter yet thought-provoking contrast to more violent villains – reminding viewers that not every antagonist is purely malicious. Gentle’s journey before becoming infamous enriches the Vigilantes storyline with both action and character depth.
If Vigilantes lets fans witness his lonelier days, his character’s future redemption becomes even more meaningful in the main series.
9 Mimic’s Hideouts
Mimic, real name Joi Irinaka, was one of the most loyal and dangerous members of the Shie Hassaikai. His Quirk allows him to control entire buildings or inanimate objects, making him a threat during confrontations in urban areas.
Having Mimic operate secret hideouts or bases during the Vigilantes timeline could introduce suspenseful infiltration arcs. The vigilantes might find themselves lost or helpless inside a home or warehouse that’s actually fighting back, raising the stakes without needing hundreds of enemies.
Mimic’s volatility and deep-seated loyalty to Overhaul would add layers of tension, especially as the vigilantes try to uncover the hidden networks connecting various criminal groups. His power makes even routine investigations potentially life-threatening.
Unlike many brawlers, Mimic tests the hero’s ability to work under pressure and improvise. Encounters with him would reward strategy over brute force, letting both sides show off their quick thinking and adaptability during high-stress situations.
8 Kurogiri’s Shadowy Missions
Kurogiri’s Warp Gate Quirk makes him the League of Villains’ ultimate support character, shuttling allies across the city and escaping trouble in an instant. In Vigilantes, Kurogiri could appear orchestrating covert operations with surgical precision.
He might help villains slip past hero patrols, transport stolen goods, or even evacuate underworld figures on the verge of exposure. For Koichi’s team, every confrontation with Kurogiri would feel like a chess game where one wrong move means instant defeat or disappearance.
Kurogiri’s scenes would push the Vigilantes to train harder and develop better teamwork, aware that their own safety is never guaranteed while he’s on the scene. The mystery shrouding Kurogiri’s true identity and motives would only add to the tension.
Fans would be excited to watch early glimpses of Kurogiri’s strict professionalism – never grandstanding, always focused on his mission, and often two steps ahead of both the heroes and his peers.
7 Overhaul’s Rise in the Yakuza
Overhaul, also known as Kai Chisaki, led the Shie Hassaikai during a time of decline, with ambitions to return the Yakuza to its former power. His Overhaul Quirk can dismantle and reconstruct anything he touches, making him one of Vigilantes’ most dangerous possible foes.
In this period, Overhaul might be seen building influence, perfecting his operation, or ruthlessly acquiring resources and new subordinates. His rise would intersect with other criminals and government agents, showing the dark partnerships keeping crime alive beneath society’s surface.
Stories centered on Overhaul could reveal how close vigilante groups sometimes came to crossing paths with major villain organizations lined with unpredictable alliances. The constant threat of Chisaki’s violent methods would make any encounter high stakes and dangerous.
Exploring Overhaul’s background before Eri’s arrival helps flesh out his motivations, allowing viewers to see how trauma and loyalty to “family” war with his ruthless ambition. Vigilantes facing Overhaul would realize there are still lines even villains refuse to cross, making them question their own methods and assumptions.

6 Spinner’s Disillusionment
Spinner, whose real name is Shuichi Iguchi, is marked by his strong sense of rejection by society due to his heteromorphic appearance. His Gecko Quirk and clear discontent with society’s unfair standards gave him a powerful motivation for eventually joining the League of Villains.
During the Vigilantes timeline, Spinner would most likely be younger, watching the world from the fringes and dealing with constant discrimination. His transformation from a shut-in to an active member of the villain community could be highlighted, showing the subtle and overt ways in which society’s bitterness shapes future threats.
Stories focusing on Spinner reveal how some villains are shaped not just by ambition, but by pain and exclusion. His slow, sometimes reluctant steps toward violence ring true for many who feel left behind, providing an important perspective on why villainy spreads among the disenfranchised.
Spinner’s eventual determination to rally others and rebel becomes even more meaningful if viewers witness the earlier disillusionment that pushes him beyond the edge.

5 Mr. Compress’s Rivalries
Mr. Compress is best known for his showmanship and clever use of the Compress Quirk, making him more unpredictable and challenging than most straightforward villains. His entertainer’s mind means he’s always two steps ahead, using theatrics to disorient both heroes and vigilantes.
In Vigilantes, Mr. Compress could be a wildcard: neither a fully committed ally nor a direct enemy, but always a complication. His clever thefts, illusions, and ability to disappear could put him at odds with various factions, including the vigilantes or even less patient villains.
The ongoing game of cat and mouse would allow for intense action while giving the safe-cracking, riddle-loving villain opportunities to interact with key players in creative ways. His character gives writers an excuse to put the vigilante squad in tough, nearly unsolvable predicaments.
Additionally, Mr. Compress’s flashes of mercy, especially when dealing with non-combatants, would provide subtle insight into why not all criminals are monsters, even in a world packed with them.

4 Dabi’s Turbulent Beginnings
Dabi is arguably one of the most mysterious villains in the franchise. His journey from Toya Todoroki to infamous arsonist is a tragic tale shaped by loss, pain, and eventual rage against the hero society. Fans remain drawn to his blue flames and chilling demeanor.
Within the Vigilantes context, Dabi’s presence would focus on his period of transformation – when he’s not yet the feared criminal, but not Toya anymore either. This era is marked by self-doubt and new realizations about what he wants and who he could become.
Episodes exploring Dabi’s struggles with his own power would resonate deeply, especially as he witnesses firsthand the flaws of both heroes and villains. The constant threat of burning everything around him would force dramatic interactions with both vigilantes and bystanders.

Watching this volatile phase of Dabi’s life gives context to his later ambition and the origins of his grudge against the hero society – and especially his father. It would also raise the stakes for the vigilantes, who would meet a villain as unpredictable as the flames he controls.
3 All For One’s Hidden Hand
All For One is the shadow that looms over both hero and villain society. Even before the events of Deku’s story, he manipulates events and individuals to ensure his power endures. His network of contacts and his Quirk make him a puppet master in every sense.
During the Vigilantes period, All For One’s influence could be felt almost everywhere, as smaller villains orbit his sphere of control, whether they know it or not. He could be shown pulling strings by recruiting, funding, or protecting promising criminals – keeping distance while maintaining dominance.
Though he might not appear in direct conflict, his rare cameos would evoke tension and shape the story’s direction. Vigilantes might hunt minor criminals, only to find out months later that they were mere pawns in a bigger plot.

2 Muscular’s Unstoppable Rampage
Muscular stands out as one of the most terrifying villains because of his overwhelming power and love of destruction. His Pump Up Quirk makes him nearly unbeatable in close combat, and he’s always searching for a real challenge.
Introducing Muscular into Vigilantes would focus on raw, devastating violence – a villain who destroys everything in his path and gives Koichi’s group a real sense of danger. His very presence could fundamentally change the tone of any arc, forcing outmatched vigilantes to use strategy and teamwork to survive.
His early career could show what happens when muscle alone disrupts both the criminal underworld and the daily life of civilians. Muscular’s willingness to fight anyone at any time poses a direct threat that neither the pro heroes nor vigilantes can ignore.

1 Shigaraki’s First Steps Toward Infamy
Tomura Shigaraki is destined to become the symbol of villainy in the My Hero Academia world. His Quirk, which can disintegrate anything he touches, is as frightening as his leadership is unstable. Early on, Shigaraki is impulsive, hungry to prove himself, yet often out of control.
Vigilantes could explore the months or years where Shigaraki first began asserting his will and piecing together his moral code (or the lack thereof). These stories would flesh out his relationship with mentor All For One, as well as his initial failures and dangerous experiments in criminality.
His earliest acts of aggression and destruction would put the vigilantes or even pro heroes in conflict with an antagonist who is raw, driven by a mix of vengeance and confusion. Shigaraki’s presence on the streets would foreshadow the calamities to come, giving every encounter stakes far beyond a simple fight.
The slow revelation of his goals, coupled with the emotional fallout from his beginnings, would turn each confrontation into something fraught with danger and meaning. Fans would finally get to witness the full path from troubled youth to one of anime’s most notorious villains.
