Background / History

During the Sludge Incident, All Might arrived in a frail, exhausted state but still transformed to resolve the crisis. Afterward, heat rose from his body as he recognized that his remaining time in hero form had run out. He left while keeping an eye on the unconscious Izuku Midoriya, apparently having reached an important decision regarding the boy. 6 7

He became U.A.'s Basic Heroics instructor, teaching Class A through combat exercises and emphasizing that presentation and confidence are part of a hero's work. 17

At the USJ attack, All Might rushed to the facility after encountering Tenya Iida, evacuated students from immediate danger, and took over the battle against Shigaraki Tomura's Nomu. He accepted Chiffon's intelligence that the creature possessed impact absorption, super regeneration, and strength comparable to his own. 39

Nomu's abilities exposed the limits of All Might's declining power. Chiffon freed him from Kurogiri's restraint and later gave him a Quirk Supplement, temporarily restoring his strength. 40 41

Following the USJ incident, All Might supported Chiffon during a police hearing but did not attempt to shield him from consequences for killing thirty-seven people. He instead expressed concern that Chiffon might go astray. 46

By the Sports Festival meteor crisis, All Might's previous exertion and the power he had already passed to Midoriya had left him increasingly weakened. He fought the alien creature despite severe injuries and used a Quirk Supplement supplied by Chiffon to recover temporarily. 112 114

In Kamino Ward, All Might confronted All For One in a televised battle. Although he landed a Detroit Smash, his body reached its limit; he ultimately spent every remaining trace of One For All while shielding an injured civilian, permanently becoming an ordinary person. 351 352

Appearance

All Might normally appears as a towering, broad-shouldered hero with a powerful physique and an unmistakably reassuring presence. His weakened form is drastically different: thin, frail, and skeletal, with sunken cheeks and hollow eyes. 39 352

• Often appears in a hero costume, though he wore a suit and tie when arriving at the USJ crisis. 39
• His muscular hero form can rapidly diminish when his strength is exhausted. 7 351
• His true form became publicly visible after his final battle with All For One. 351 352

Personality

All Might embodies reassurance under pressure. Even when injured or outmatched, he focuses first on protecting civilians, students, and fellow heroes. His repeated declaration that everything is all right is meant to steady those around him. 39 114

As a teacher, he cares deeply for both Midoriya and Chiffon without openly favoring either. He watches Midoriya's progress with pride, recognizes Chiffon's potential, and seeks to guide both boys rather than simply solve their problems for them. 13 39 46

He is compassionate but does not believe heroism excuses wrongdoing. During Chiffon's disciplinary case, he respected the police decision while still advocating that the student had the potential to avoid a darker path. 46

Abilities & Skills

One For All

All Might formerly wielded One For All, a power that gave him overwhelming physical strength, speed, and destructive striking force. By the later stages of the story, he had already passed the Quirk to Izuku Midoriya and was operating on its dwindling residual power. 112 351

• Defeated villains and rescued several students in the span of an instant at USJ. 39
• Could produce massive shockwaves with techniques such as Carolina Smash and Detroit Smash. 40 351
• Retained enough power to fight All For One despite his declining condition. 351
• His remaining power was fully exhausted while defending a civilian from All For One's attack. 352
• His transformation time and combat capacity had been severely limited before that final depletion. 7 112

Combat Speed and Rescue

All Might combines high-speed movement with battlefield awareness, allowing him to protect multiple people while engaging enemies.

• Carried several students, including Chiffon, to safety in a single movement during the USJ attack. 39
• Reached Chiffon in time to repel the alien creature after Midoriya delayed its attack. 114
• Prioritized evacuation and ordered the students away from battles beyond their ability to handle. 39 112

Hero Instruction

As U.A.'s Basic Heroics teacher, All Might provides practical instruction in combat and hero conduct.

• Introduced Class A to combat training and custom Quirk-based uniforms. 17
• Explained mock hero-versus-villain missions focused on capturing opponents or securing a nuclear weapon. 18
• Encouraged Midoriya's early effort to regulate One For All instead of relying on self-destructive full-power attacks. 13

Relationships

• Izuku Midoriya — Successor and mentee. All Might passed One For All to Izuku and continues to guide him, taking pride in his progress and eventual growth into an independent hero. 13 112 442
• Chiffon — Student he values highly. All Might relied on Chiffon's analysis during the USJ attack, accepted his Quirk Supplements in critical battles, and regarded him as an exceptionally gifted student. 39 41 46
• Shota Aizawa — U.A. colleague and co-instructor. Aizawa criticizes All Might for arriving late to USJ, while All Might apologizes sincerely and assists the injured teacher. 39
• All For One — Long-standing enemy. Their Kamino Ward battle ends with All Might exhausting the final remnant of One For All. 351 352
• Endeavor — Fellow top hero and rival. Endeavor repeatedly seeks to prove himself beside All Might, including during the alien-creature crisis. 113 114
• Gran Torino — Ally who intervenes during the Kamino battle and carries the exhausted All Might away from the clash. 351 354
