My Hero Academia [RPG]

The Billboard Chart annually ranks professional heroes based on popularity, cases solved, contributions, and public perception. Currently, in the most recent ranking (just as the series begins), the Top Heroes are:

All Might — The Symbol of Peace, undisputed number 1. His presence keeps national morale high; his constant victory against villains defines the current era.

Endeavor — Number 2, a fierce and efficient fire hero, known for his intensity and high capture rate. He runs a large and demanding agency.

Hawks — Number 3, the fastest hero, with telekinetic wings and feathers. Popular for his youthful charisma and efficiency in aerial rescues.

Best Jeanist — Number 4, master of fiber control and fashion. Focused on public image and discipline.

Mirko — Number 5, the rabbit heroine, a specialist in hand-to-hand combat, fierce and independent.

Other notable heroes include Edgeshot (a ninja with a foldable body), Present Mic (announcer and sound hero), and Midnight (a sleep-inducing heroine). The Top 10 changes slightly each year, but All Might remains unchallenged. These heroes operate daily throughout Japan, with agencies in major cities, and their fame fuels hero culture as the new generation at UA aspires to join them.

Japan strictly regulates Quirks nationwide, with laws applied uniformly across the country, including Musutafu. The Constitution and the Public Safety Quirk Law (established after the initial chaotic period) prohibit the public use of Quirks without a provisional or professional hero license. Any intervention in crimes, rescues, or self-defense using a Quirk without a permit is considered illegal use and may result in immediate arrest. Mandatory Quirk registration (before age 6) is federal law, with penalties for non-compliance. Dangerous Quirks receive additional restrictions: supervised use, specific prohibitions, or government monitoring. Vigilantism is a serious crime, equated with villainy. In Musutafu, municipal ordinances add local layers: restricted zones for flight or destructive Quirks, fines for collateral damage, and mandatory evacuation protocols after battles. The Hero Public Safety Commission oversees everything, coordinating with the police for arrests and trials in special courts. Prisons have anti-Quirk cells (suppressors, containment camps). Currently, these laws maintain order, but they generate debate about whether they overly restrict individual freedom and exclude those who don't fit into the hero system.

Although All Might maintains peace as the undisputed Symbol, modern society is experiencing a gradual and worrying increase in threats. Common villains are proliferating on the streets: Quirk-enhanced robberies, nighttime assaults, and impulsive attacks cause daily incidents in Musutafu and other cities. Organized groups are beginning to emerge from the shadows, recruiting the marginalized: discriminated heteromorphs, resentful Quirkless, and users with "dangerous" Quirks rejected by the system. The League of Villains, still small and chaotic, represents the most visible symptom of this discontent, with sporadic attacks that challenge the heroic order. Social tensions are rising: over-reliance on All Might is generating criticism of the system ("What will happen when he's gone?"), while the media amplifies every heroic failure, eroding public trust. Heteromorphs and Quirkless individuals feel increasingly excluded, and extremist movements (like the Creature Rejection Clan) are gaining traction online and at demonstrations. Currently, society maintains a facade of stability, but beneath the surface, discontent is simmering, threatening to shatter the fragile equilibrium built after decades of chaos.

Daily life in Japan, especially in cities like Musutafu, is completely shaped by the existence of Quirks. Eighty percent of the population wakes up every morning with a superhuman ability that influences everything: from how they dress (clothes with openings for tails, wings, or mutations) to how they get around (public transportation with special sections for large or high-speed Quirks). On the streets, people avoid using Quirks publicly without a license: even a simple accidental shove with superhuman strength can be a crime. Shops sell "support items" like recoil-proof gloves, glasses that block visual Quirks, or shoes with shock absorbers for extreme jumps. Everyday jobs prioritize useful Quirks: a delivery person with enhanced speed earns more, a construction worker with superhuman strength is hired instantly, while Quirkless people or those with "useless" Quirks face employment barriers. The routine includes constant precautions: "No Quirk Use Here" signs, no-flying zones in parks, and schools that teach Quirk control from preschool onward. On weekends, families watch heroic shows on TV, buy All Might merchandise, and celebrate local victories. However, discrimination persists: heteromorphs avoid certain areas due to hostile stares, and minor accidents (like a Quirk triggered by a sneeze) result in fines or social embarrassment. Life is vibrant, convenient in many ways, but always under the shadow of responsibility and the fear of losing control.

No Quirk is limitless: all possess inherent physical, mental, or situational weaknesses. Emitter users suffer backlash from overuse, such as burns, muscle exhaustion, or loss of consciousness (e.g., Bakugo with continuous explosions). Transformation users require bodily energy and cause extreme fatigue if maintained for too long. Mutant users face permanent disadvantages: chronic pain, difficulty with daily activities, or dependence on accessories. Many Quirks rely on emotions (anger powers explosions, calmness controls ice), and stress or trauma can cause them to malfunction. External factors such as weather, terrain, or lack of sleep affect performance. Constant training is essential to expand limits, but exceeding them can cause serious injury or death. Currently, education and counseling emphasize knowing and respecting these limits from childhood, as ignoring them is a common cause of accidents and hospitalizations. Even top heroes like All Might face secret restrictions due to cumulative damage, a reminder that Quirks, while superhuman, are tied to the fragile human body and mind.

Quirk registration is mandatory by law from childhood: all individuals with a Quirk must register it with the government before the age of six, providing its name, description, category (Emitter, Transformation, Mutant), known limitations, and potential danger. The process includes medical examinations and evaluations by specialized counselors. Quirks are officially classified into three standard categories, with subcategories for danger (low, medium, high). Quirks considered "dangerous" (such as disintegration or mind manipulation) receive additional restrictions: supervised use, specific prohibitions, or constant monitoring. Changing a Quirk's name is possible, but requires approval and usually occurs in adolescence when the user has a better understanding of it. The information is confidential in theory, but accessible to hero agencies, police, and employers in justified cases. The registry prevents abuses and facilitates social control, but it creates tensions: Quirkless individuals are excluded, and heteromorphs are immediately identifiable by their appearance. Currently, the system operates throughout Japan, with national databases that allow for rapid tracking in emergencies, although debates about privacy and discrimination persist.

Japanese police work closely with professional heroes, but their primary role is the containment, investigation, and formal arrest of villains. Officers cannot use Quirks in combat unless they possess a Hero License (which is rare), so they rely on reinforced riot gear, anti-Quirk containers (such as power-nullifying handcuffs or cells with suppressants), and protocols to minimize harm. When a villain is captured by a hero, the police take immediate custody for legal proceedings: interrogations, trial, and sentencing in special prisons with anti-Quirk measures. The Hero Public Safety Commission coordinates joint operations in major cases. The police also handle minor crimes without Quirks, traffic, evacuations, and crowd control after battles. Currently, they face criticism for being "secondary" in the public perception (heroes receive the glory) and for their limitations in confronting high-level threats without heroic support. In cities like Musutafu, police and heroic patrols coexist daily, restoring order after incidents and maintaining the facade of a functioning society.

The media plays a central role in today's society, turning heroes into national celebrities. Daily television programs like "Hero Hour" or "All Might Specials" broadcast live battles, interviews, and Quirk analyses, while magazines, social media, and streaming channels generate constant content: Billboard Chart rankings, sidekick vlogs, agency documentaries, and massive merchandising (figures, clothing, themed food). All Might dominates hero culture as the Symbol of Peace: his smile, iconic catchphrases ("Fear not, for I am here!"), and constant victories inspire hope and boost public morale. Reporters, like those from the channel covering incidents in Musutafu, compete for exclusive stories, often arriving on the scene before the police. Hero culture fosters idol worship, with children dreaming of becoming heroes and adults buying sponsored merchandise. However, this overexposure creates pressure: heroes must maintain a perfect image, and media scrutiny amplifies failures or collateral damage. Currently, the media contributes to social tension by highlighting both heroic greatness and the rise of villains, shaping the public perception that peace depends entirely on figures like All Might.

Quirk Counseling is a free, government-mandated service offered to all children once their Quirk manifests (generally between the ages of 4 and 5). Specialized counselors, often with Quirks related to empathy or analysis, help children understand, manage, and accept their Quirk to prevent serious accidents, such as self-inflicted injuries or harm to others. In primary schools and kindergartens, the program includes regular Quirk ethics education sessions, practical control exercises (such as extinguishing fires, floating objects without breaking them, or managing physical mutations), and workshops for parents on how to support development without stigmatizing. Quirkless children receive special guidance to avoid discrimination and foster self-esteem. The system aims for early social integration, but in practice, it often pressures children to "normalize" their Quirks, suppressing unique expressions (especially in heteromorphs) to fit into society. Cases of emotional overload or rejection trauma persist, and some counselors are criticized for overly rigid approaches. Currently, counseling is an integral part of childhood education in Japan, with an emphasis on preventing the illegal use of Quirks from childhood and preparing future citizens for a world where 80% possess superpowers.

Hero agencies serve as operational bases for professional heroes, managed by the Hero Public Safety Commission. The typical structure includes a lead hero (the owner or leader) who hires sidekicks (subordinate heroes, often less experienced) for patrols, rescues, and missions. Agencies handle salaries based on cases solved, popularity, and contributions, with additional revenue from sponsorships and merchandising. Early examples include Endeavor's agency (focused on efficiency and rigorous training), Best Jeanist (emphasizing image and discipline), and Ingenium's (large, with many sidekicks). Sidekicks are licensed heroes who support the leader: they perform backup tasks, cover large areas, and gain real-world experience. Many aspire to rise through the ranks or open their own agencies, but most remain in the role for financial stability. Agencies offer internships to UA students after the Sports Festival (for observation) or work-studies (with a provisional license, acting as actual sidekicks). The system encourages collaboration with the police for arrests and damage control, but relies heavily on top heroes like All Might to maintain public morale. Currently, agencies operate daily in cities like Musutafu, responding to threats and training the next generation.

Major cities like Musutafu (located in Shizuoka Prefecture), Hosu, and the greater Tokyo metropolitan area adapt their infrastructure to the world of Quirks: buildings with damage-resistant reinforcements (resistant glass, flexible structures), public transportation with special cars for mutant Quirks, traffic lights and signs designed for speed or flight Quirks, and rapid evacuation zones. Musutafu, the central city of the series, combines everyday urban life with a constant heroic presence: regular patrols, visible agencies, and hero announcements on giant screens. Daily life integrates Quirks into everything: fashion with adaptable clothing (for tails, wings, or mutations), shops selling support items, schools with Quirk counseling, and employment that prioritizes useful abilities. Villainous incidents occur frequently, but heroes respond quickly, restoring order. Hosu, for example, is a more industrial city with dark alleyways prone to nighttime crime. The bustle includes crowds cheering heroes after battles, reporters covering events, and civilians adjusting to restrictions such as the ban on public use of unlicensed Quirks. Modern urbanization reflects the balance between potential chaos and the peace maintained by the Symbol of Peace, with underlying tension from the gradual rise of villains.

Vigilantism is strictly illegal in today's society: anyone who uses their Quirk to fight crime, rescue people, or intervene in dangerous situations without a provisional or professional hero license is considered a criminal, regardless of their intentions. The Hero Public Safety Commission and law enforcement classify these actions as illegal Quirk use, which can result in arrest, fines, or being labeled a villain. The key difference is that licensed heroes operate under regulations, insurance, and protocols to minimize collateral damage, while vigilantes act without oversight, creating risks of chaos, abuse, or serious errors. Many vigilantes emerge from frustration with the hero system: they see heroes preoccupied with fame or major cases, leaving marginalized areas unprotected. The illegal use of Quirks also includes crimes like enhanced theft, extortion, or direct attacks, but vigilantism occupies a gray area: "good" actions without permission. In the present day, right at the start of the series, vigilantism persists in the shadows of cities like Musutafu, though most vigilantes end up captured or absorbed by organized crime. Legendary figures from the past (such as those from the initial chaotic period) inspire some, but the law is clear: without a license, any intervention with a Quirk is a crime. This fuels debates about the accessibility of heroism and the pressure on the new generation to maintain legal order.

Heteromorphs, also known as Mutant-type Quirk users, possess permanent physical alterations directly related to their powers, such as extra limbs, tails, wings, horns, scaly skin, or non-human body structures. These mutations grant complex abilities that cannot be deactivated, leading to everyday inconveniences: difficulty finding suitable clothing, problems sitting on standard furniture, or constant discomfort in environments designed for "normal" bodies. In today's society, heteromorphs face systematic discrimination and deep-seated prejudice, even from other Quirk users, due to their "monstrous" or "unnatural" appearance. They are labeled as "monsters," "sick," or "threats," resulting in social exclusion, job rejection, childhood bullying, and constant stigma. In rural areas or small towns, prejudice is more intense, while in metropolises like Musutafu there is somewhat more assimilation, though it doesn't eliminate the problem. This drives some heteromorphs toward crime or vigilantism, as society rejects them and sees them as inherently dangerous. Extremist groups like the Creature Rejection Clan openly promote their eradication through hate crimes. Characters like Mezo Shoji (Class 1-A) conceal scars of childhood abuse caused by their appearance, and examples like Spinner (Shuichi Iguchi) show how constant rejection breeds resentment and radicalization. The law requires Quirk registration, but permanent mutations make heteromorphs immediately identifiable, increasing surveillance and scrutiny. Childhood Quirk counseling attempts to help, but often pressures individuals to suppress differences rather than promote acceptance, exacerbating mental and social tensions.

All For One operates in the deepest shadows as the most powerful legendary figure in the villain world, mentor, and adoptive father figure to Tomura Shigaraki. His primary Quirk allows him to steal other Quirks through touch, use them as his own, and transfer them to others; he has accumulated hundreds over decades. A longtime enemy of All Might (who severely defeated him in the past, leaving him injured and dependent on life support), All For One manipulates events from behind the scenes, without direct public exposure. Most of society is unaware of his current existence or considers him a myth; only select villain circles know of his influence. Currently, he remains hidden, secretly guiding Shigaraki and the League of Villains, with the ultimate goal of corrupting and destroying the legacy of One For All and hero society. His presence is subtle, but his legacy of past chaos shapes the current villain world.

Tomura Shigaraki leads the League of Villains, a small, emerging group of villains operating from a hidden hideout, with the primary goal of destroying hero society and eliminating All Might, the Symbol of Peace. Shigaraki, a disheveled young man with messy grayish-blue hair, pale skin, and desiccated hands attached to his body as accessories, possesses the Quirk Decay: he disintegrates anything he touches with his five fingers, and the effect spreads rapidly. His personality is childish, capricious, frustrated, and destructive; he scratches his neck when angry and speaks in video game terms. Raised by All For One after childhood trauma, he views society as rotten and seeks total chaos. The League of Villains, in its initial state, is a small, chaotic group with no real structure, focused on demonstrating its power and causing disruption. Key members include: Kurogiri (confidant and warp gate, handles logistics and recruitment) Other early recruits like Spinner (loyal, shares interests with Shigaraki) The group recruits disaffected misfits, plans sporadic attacks, and values ​​its close members, but Shigaraki prioritizes impulsive destruction over refined strategy. Currently, the League operates in the shadows, preparing moves to challenge the heroic order.

In today's society, Quirk-related crime poses a constant and growing threat, as individuals use their superhuman abilities to commit crimes ranging from petty theft to massive destructive attacks. Public use of Quirks without a license is illegal, and those who use them for criminal purposes are classified as villains under the law. Common villains include street opportunists who exploit Quirks for assault, extortion, or vandalism, while organized groups seek larger-scale chaos. The Hero Public Safety Commission and the police collaborate to contain them, but the rise in attacks creates social tension. Many villains emerge from discrimination (especially against heteromorphs), poverty, trauma, or rejection of the hero system. Vigilantism is illegal and can lead to being labeled a villain. Currently, scattered villains operate in cities like Musutafu, causing daily incidents that professional heroes resolve, though public fear of dangerous Quirks persists and fuels prejudice.

UA High School offers four main departments: Hero Course (Classes 1-A and 1-B, focusing on combat and heroism), General Education (CK classes, standard education with the possibility of transferring to the Hero Course via the Sports Festival), Support Course (Classes F, G, H; students develop heroic equipment and gadgets, like Mei Hatsume in 1-H, who invents innovative and eccentric prototypes) and Management/Business Course (classes focused on heroic management, marketing, agency financing and hero promotion). The Support Course creates tools that enhance Quirks (suits, weapons, gadgets), while the Management Course provides training in business, contracts, and public image management. All departments share the fortified campus and events like the Sports Festival and the School Festival, where Support students showcase inventions and Management handles logistics and audience engagement. Currently, these departments operate alongside the Hero Course, contributing to the hero ecosystem and offering opportunities for students not focused on direct combat.

UA High School boasts a faculty composed entirely of active and retired pro heroes, who employ unconventional teaching methods and possess the authority to expel students at any time. The principal is Nezu, an intelligent animal with the Quirk High Specs (superhuman intelligence). Key professors in the Department of Heroes include: Shota Aizawa (Eraser Head): Homeroom of Class 1-A, Quirk Erasure (cancels Quirks by looking), teaches heroic ethics and evaluates with tough tests. Sekijiro Kan (Vlad King): Class 1-B Homeroom, Quirk Blood Control. Toshinori Yagi (All Might): Teaches the Fundamentals of Heroism, symbol of peace and mentor. Hizashi Yamada (Present Mic): English teacher, Quirk Voice (massive sound wave), enthusiastic announcer. Nemuri Kayama (Midnight): Professor of Modern Heroic Art, Quirk Somnambulist (sleep-inducing by scent). Ken Ishiyama (Cementoss): Professor of modern literature, Quirk Cement (manipulates cement). Ectoplasm: Professor of modern mathematics, Quirk: Clones (creates duplicates). Chiyo Shuzenji (Recovery Girl): School nurse, Quirk Heal (accelerates healing in exchange for energy). Thirteen: Rescue teacher, Quirk Black Hole (creates black holes). The instructors collaborate on training, exams, and events, prioritizing individual growth under the motto "Plus Ultra." Their style is flexible yet demanding, tailored to prepare real heroes for a dangerous world.

Class 1-B is the other first-year class in the Hero Department at U.A. High School, running parallel to Class 1-A and consisting of 20 students. Their homeroom teacher is Sekijiro Kan (Vlad King), a pro hero with the Blood Control Quirk, which allows him to manipulate his own blood as a weapon. The class is characterized by a disciplined and consistent approach: they avoid major problems (unlike Class 1-A, which attracts villainous incidents), allowing them to develop more steadily and quietly. Many students share a friendly (sometimes intense) rivalry with Class 1-A, especially Neito Monoma, who constantly provokes and tries to surpass 1-A out of envy for their visibility and "luck" in actual battles. The class representative is Itsuka Kendo, a charismatic and level-headed leader with the Quirk Big Fist (enlarging her hands). The students include:

Neito Monoma (Copy / Phantom Thief) Itsuka Kendo (Big Fist / Battle Fist) Tetsutetsu Tetsutetsu (Steel / Real Steel) Yosetsu Awase (Weld) Ibara Shiozaki (Vines / Vine) Juzo Honenuki (Softening) Kinoko Komori (Mushroom) Setsuna Tokage (Lizard Tail Splitter) Yui Kodai (Size) Reiko Yanagi (Poltergeist) Hiryu Rin (Scales) Pony Tsunotori (Horn Cannon) Kosei Tsuburaba (Solid Air) Shihai Kuroiro (Black) Manga Fukidashi (Comic) Jurota Shishida (Beast) Nirengeki Shoda (Twin Impact) Togaru Kamakiri (Razor Sharp) Kojiro Bondo (Cemedine) Sen Kaibara (Gyrate)

The class buzzes with internal and external competition, focusing on rigorous training and proving they can shine without the media spotlight that 1-A has. They participate in joint events like the Sports Festival and drills, always ready to challenge their rivals.

Class 1-A at U.A. High School is the first-year Hero Course homeroom class, comprised of 20 students who were recently admitted after passing the entrance exam. Currently, at the start of the semester, the students are adjusting to the intense routine under the supervision of their homeroom teacher, Shota Aizawa (Eraser Head), who assesses their potential with rigorous tests such as the Quirk Apprehension Test. The class is notable for including six of the highest scores on the entrance exam (Katsuki Bakugo, Eijiro Kirishima, Ochaco Uraraka, Tenya Ida, Izuku Midoriya, and Fumikage Tokoyami) and two students admitted by recommendation (Shoto Todoroki and Momo Yaoyorozu). Tenya Ida serves as the class representative, with Momo Yaoyorozu as the vice-representative.

The students, listed by seat, are: Yuga Aoyama (Naval Laser / Can't Stop Twinkling) Mina Ashido (Acid / Pinky) Tsuyu Asui (Frog / Froppy) Tenya Ida (Engine / Ingenium) Ochaco Uraraka (Zero Gravity / Uravity) Mashirao Ojiro (Tail/Tailman) Denki Kaminari (Electrification/Chargebolt) Eijiro Kirishima (Hardening/Red Riot) Koji Koda (Anivoice / Anima) Rikido Sato (Sugar Rush/Sugarman) Mezo Shoji (Dupli-Arms / Tentacole) Kyoka Jiro (Earphone Jack / Earphone Jack) Hanta Sero (Tape/Cellophane) Fumikage Tokoyami (Dark Shadow/Tsukuyomi) Shoto Todoroki (Half-Cold Half-Hot / Shoto) Toru Hagakure (Invisibility/Invisible Girl) Katsuki Bakugo (Explosion / Great Explosion Murder God Dynamight) Izuku Midoriya (One For All / Deku) Minoru Mineta (Pop Off / Grape Juice) Momo Yaoyorozu (Creation / Creati)

The class buzzes with diverse dynamics: intense rivalries (like those between Bakugo and Midoriya), budding friendships, and a focus on pushing boundaries under the motto "Plus Ultra." Students participate daily in physical training, lectures on hero laws, and battle simulations, preparing for provisional licenses and future internships.

U.A. High School, located in Musutafu, Japan, is the country's most prestigious hero academy, renowned for its rigorous training program and fortified campus with anti-intrusion security barriers. The school offers four departments: Hero Course (for aspiring professional heroes), General Education (standard studies), Support Course (heroic team development), and Business Course (heroic management and marketing). The Hero Course, divided into classes such as 1-A and 1-B for first-year students, has just begun the semester with newly admitted students who passed an entrance exam that includes a written test and a practical exercise against simulated villain robots. The teachers are active professional heroes, such as Shota Aizawa (Eraser Head), who teaches in Class 1-A and assesses Quirks with exercises like the Quirk Apprehension Test; Hizashi Yamada (Present Mic), the English teacher; and Nemuri Kayama (Midnight), the instructor of modern hero art. UA emphasizes the motto "Plus Ultra," promoting exceeding limits through battle drills, lectures on heroic laws, and events like the annual Sports Festival. Currently, the school is buzzing with the energy of freshmen adapting to intense routines, preparing the next generation for provisional licenses and agency internships.

The professional hero system operates under the supervision of the Hero Public Safety Commission, a government entity that regulates heroic activity in Japan and globally. Licensed heroes can publicly use their Quirks to combat villains and disasters, receiving salaries based on cases solved, popularity, and social contributions. The Billboard Chart ranks heroes annually by these criteria, with All Might holding the number one spot as the Symbol of Peace. Hero agencies serve as bases of operations, where top heroes hire sidekicks (subordinate heroes) for patrols, rescues, and missions. Examples include Endeavor's agency, focused on efficiency, and Best Jeanist's, geared toward fashion and public relations. Heroes must adhere to strict ethical codes, prioritizing minimizing collateral damage and cooperating with the police, who handle arrests and containment. The system fosters public idolatry through media and merchandising, but faces criticism for its reliance on figures like All Might, which puts pressure on the new generation to maintain peace in a world where villains with illegal Quirks proliferate daily.

Quirks in Today's Society In contemporary society, approximately 80% of the world's population possesses a Quirk, a unique superhuman ability that typically manifests around the age of four. Quirks are classified into three main categories: Emitter (emitting energy or substances, such as fire or explosions), Transformation (temporarily altering the user's body, such as hardening the skin), and Mutant (permanent changes to anatomy, such as tails or wings). Quirk registration is mandatory with the government, and public use is strictly prohibited without a provisional or professional hero license to prevent accidents and abuse. Individuals without Quirks, known as Quirkless and comprising the remaining 20%, face social discrimination and employment limitations, as many jobs favor superhuman abilities. Quirks influence all aspects of daily life, from architectural adaptations in buildings to withstand Quirk damage to educational programs that teach control and ethics. However, problems such as physical overload in users (backlash) persist, and the stigma against mutant Quirks or "heteromorphs" generates social tensions, with marginalized groups promoting equality or Quirk supremacy.

Quirks, known as "Meta Abilities" in some contexts, first emerged in human history in Qing Qing City, China, when a baby was born with the ability to emit light from its body. This event marked the beginning of a chaotic era known as the "Advent of the Supernatural." Initially, Quirks manifested unpredictably, causing social panic, discrimination, and the collapse of existing governmental structures. Many individuals with powerful Quirks abused their abilities, while others, fearful, organized into vigilante groups to restore order. Figures like All For One, a legendary villain capable of stealing and granting Quirks, exacerbated the chaos by accumulating power and manipulating others during this turbulent time. Over generations, Quirks became hereditary and more common, evolving through genetic mixing, which led to more complex and potent Quirks. Global society gradually adapted, implementing laws to regulate its use, but the initial period of instability left a legacy of inequality and conflict that persists to this day.
