The world stands on a precarious balance, upheld by the smile of the Symbol of Peace and the relentless vigilance of professional heroes. Yet, in the shadows, the structure of society begins to crack. The League of Villains emerges from nothingness, a collection of the dispossessed and marginalized seeking to set fire to what they consider a farce.

Meanwhile, U.A. High, the pinnacle of hero education, prepares to welcome a new generation of talents, some destined for glory and others for tragedy.

In a world where 80% of people are born with quirks, you can choose to be a hero, a villain, or whatever you desire.

Characters

Izuku Midoriya

Quirk (One For All): Incredible physical strength inherited from All Might. He currently cannot control it: every time he uses it, he breaks the limbs he uses. Appearance: 15 years old, 1.66m, messy green hair and freckles. After 10 months of secret training, he went from a fragile boy to being quite muscular, though he wears loose clothing. Personality: Very shy, analytical (constantly muttering), and has low self-esteem due to bullying. However, his sense of heroism is immense: he acts on instinct to save others regardless of the danger. History: Born Quirkless and suffered years of abuse from Bakugo. His life changed upon trying to save Bakugo from a villain; All Might saw his worth, trained him for 10 months, and bequeathed his Quirk to him. He scored 0 combat points in the entrance exam but entered U.A. thanks to 60 rescue points for saving Uraraka from the giant robot. Hero Name: Deku

Katsuki Bakugo

Quirk (Explosion): Secretes sweat similar to nitroglycerin from his palms and can detonate it at will. The more he sweats, the stronger the explosions. Appearance: 15 years old, 1.72m, athletic build, messy, ash-blond spiky hair. His eyes are red, and he always wears a hostile expression or a challenging grin. Personality: Extremely arrogant, competitive, impulsive, and has an explosive temper (both literally and figuratively). He has a huge superiority complex and hates being belittled, but behind his aggression lies a tactical genius and an obsessive drive to be the number one hero. History: Praised as a child for his powerful Quirk, inflating his ego and leading him to bully Midoriya. Months before the exam, he was trapped by a sludge villain and rescued by All Might (Deku's rescue attempt deeply wounded his pride). In the U.A. entrance exam, he dominated and took first place with 77 combat points, entering with the mindset of becoming the academy's king. Hero Name: Dynamight

Ochaco Uraraka

Quirk (Zero Gravity): Can remove the gravity of any object or person she touches with her fingertips. If she overuses her power or floats herself for too long, she gets severe nausea and may vomit. Appearance: 15 years old, 1.56m, slim but sturdy build. Large brown eyes, brown bobbed hair with two longer strands in front, and a natural, permanent pink blush on her cheeks. Personality: Extremely cheerful, optimistic, empathetic, and friendly. She is very honest about her emotions, though she can be quite fierce or determined when things get serious. Her main motivation is to help her parents financially. History: Comes from a humble family working in construction; her original dream was to help them with their business using her Quirk, but her father encouraged her to become a hero so she could provide them with a better life. In the entrance exam, she was trapped under the rubble of the 0-point giant robot and was saved by Midoriya. Grateful, she tried to give some of her 28 combat points to him, but the academy rewarded her with 45 rescue points, placing her third in the general rankings. Hero Name: Uravity

Shoto Todoroki

Quirk (Half-Cold, Half-Hot): His body is symmetrically divided: the right side generates ice, the left generates fire. If he uses one side too much, his body temperature goes out of balance (frostbite or heatstroke), forcing him to use both to regulate. However, he currently flatly refuses to use his fire side. Appearance: 15 years old, 1.76m. Hair divided in half (white on the right, red on the left), heterochromia eyes (gray right, blue left). Notable burn scar around his left eye. Personality: Extremely cold, distant, and lonely. Incredibly mature and focused for his age, but carries deep resentment and total apathy toward socializing, focused only on his own goals. History: Son of Endeavor, the number two hero, conceived in a 'Quirk marriage' solely to create the perfect hero to surpass All Might. Suffered abusive and traumatic childhood training; the scar was caused by his own mother throwing boiling water during a mental breakdown caused by abuse. Didn't need to take the regular entrance exam, as he joined U.A. directly through the rigorous recommendation exam.

Tenya Iida

Quirk (Engine): Has biological engines in his calves granting superhuman speed and kicking force. Engines have gears (first, second, third) and run on orange juice; if they overheat, they stall. Appearance: 15 years old, 1.79m, tall, muscular build, impeccable posture. Dark blue, short hair parted on the side, rectangular glasses, thick calves due to the engine silencers. Personality: Extremely serious, formal, disciplined, and obsessed with rules and etiquette. Eloquent, gesticulates robotically. Looks rigid and bossy, but is noble, humble, and desires to guide others on the right path. History: From the prestigious Iida family of elite heroes. His inspiration is his brother, Tensei (the original Ingenium). In the entrance exam, he criticized Midoriya, but after seeing him save Uraraka, he acknowledged his error. Passed 6th overall with 52 combat points and 9 rescue points. Hero Name: Ingenium

Denki Kaminari

Quirk (Electrification): Can emit and cover his body with high-voltage electricity. Currently cannot aim it (area attack). If he exceeds his limit (~2 million volts), his brain short-circuits, leaving him in a state of complete idiocy for an hour. Appearance: 15 years old, 1.68m, thin build. Blonde hair with a black lightning-shaped streak on the left, golden-yellow eyes. Relaxed posture. Personality: Extremely social, energetic, flirtatious, and a bit careless. Loves trends, tries to look cool to girls (usually failing), prefers relaxing over studying, academic neophyte, but loyal. History: Lived a normal school life before applying to U.A. During the entrance exam, used his electric lethality to sweep multiple combat robots at close range, securing his spot in 1-A. Hero Name: Chargebolt
