Midoriya

Biodata

Power Progression

Background / History

Midoriya and Katsuki Bakugo have been classmates since kindergarten. Midoriya grew up admiring Bakugo’s talent, even as Bakugo became increasingly unwilling to accept help from others. Despite their strained relationship, Midoriya continued to regard him as someone worth surpassing 28.

Originally Quirkless, Midoriya received a powerful Quirk from someone whose identity he promised to protect. He admitted this much to Jilan Jiyu when questioned about his unfamiliarity with his own ability 28 371. All Might later confirmed that their shared Quirk is One For All, a power that accumulates strength as it passes between successors 428.

Appearance

• Hair: Green and curly, described by Jilan as “seaweed-green” 7 12.
• Quirk activation: Early concentrated attacks make the blood vessels in the affected limb visibly surge; later whole-body enhancement produces green electrical arcs 18 19 187.

Personality

Midoriya is nervous in unfamiliar or confrontational situations. He becomes flustered around Bakugo, blushes at Uraraka’s kindness, and initially struggles with the attention of the Sports Festival crowd 6 16 103. His habit of muttering observations is conspicuous enough for Iida to reprimand him during the entrance exam briefing 7.

His hesitation rarely prevents him from trying to help. He repeatedly volunteers for work despite his physical limitations, refuses to abandon Iida to Stain, and stays behind on a supposedly bomb-rigged ship so his companions can leave safely 78 94 185. He also remembers the help others give him and remains grateful for it 28.

Midoriya’s determination can become self-destructive. Against Todoroki, he continues attacking with badly damaged fingers despite the risk of permanent injury. Yet he is also quick to look for possibilities: while recovering afterward, he briefly considers how his abnormally flexible injured arm might be useful in combat 133 135.

Abilities & Skills

One For All

A transferable Quirk that combines the ability to store power with the ability to pass that power to another person. Its accumulated strength increased through successive holders before reaching All Might and Midoriya 428.

• Enhanced strength: Can destroy a giant exam robot and produce an attack powerful enough to tear through multiple building floors 12 24.
• Wind pressure: Finger flicks generate blasts capable of shattering Todoroki’s ice and throwing Hagakure out of the arena 126 133.
• Whole-body enhancement: Improves speed, agility, and close-range movement while surrounding him with green electrical arcs 187 191.
• Early limitation: Excessive output causes severe damage to his own body. Aizawa warns that becoming immobile during an operation would also endanger teammates who tried to rescue him 18 24.
• Unexplained disturbance: While watching Jilan fight Todoroki, he briefly feels part of All Might’s power disappear before it returns 139.

Combat Analysis and Strategy

Midoriya studies opponents’ habits, Quirks, and surroundings, then uses that information to create openings 23 24 35.

• Anticipates Bakugo’s opening ambush and throws him without using his Quirk 23.
• Draws Bakugo beneath the objective room and uses a destructive upward attack to enable Uraraka’s winning move 24.
• Identifies how Aizawa’s goggles conceal whose Quirk he is erasing, preventing the villains from coordinating effectively 35.
• Recognizes inconsistencies in a staged villain incident, concludes that the enemy is All Might, and correctly bets that the threatened bombs do not exist 89 94 95.
• Develops a route through I-Island’s elevator shaft using Uraraka’s Zero Gravity and considers how to divide the group against further opposition 353.

Close Combat and Mobility

Midoriya can fight tactically even when avoiding his Quirk, though his early unenhanced strength is only slightly above that of an ordinary student 23 78.

• Grappling and evasion: Uses throws, dodges, and capture tape against Bakugo 23.
• Enhanced acrobatics: Slips beneath Stain’s blade, plants a hand on the ground, twists into a punch, and vaults away 187.
• Industrial-course movement: Overtakes Sero through agile jumps during rescue training 212.
• Terrain limitation: His jumps depend on traction; a cylindrical steel pipe causes him to slip and fall 212.
• Control training: Spars with Tiger, whose supple evasions challenge his reactions and ability to regulate output 402.

Rescue Skills

• Uses a rope to pull Asui from beneath a collapsed house while respecting the exercise’s requirement to treat her as a civilian without a usable Quirk 82.
• Carries the injured Aizawa away from the USJ battle and briefs All Might on the enemies’ abilities 45.
• Learns an aerial movement technique from an All Might documentary and applies it during the I-Island crisis 363.

Equipment / Weapons / Items

• Melissa’s gauntlet — A wristband-deployed support device that lets him deliver powerful attacks without injuring his arm. It has a three-use limit; its final use cracks, but does not open, All Might’s steel cage, after which it disintegrates 346 347 363 364.
• Bakugo’s stored-sweat gauntlet — Temporarily uses it during their practical final exam to fire a maximum-power explosion at All Might from close range 230.
• Capture tape — Attempts to bind Bakugo’s leg during indoor combat training 23.
• Steel plate — Uses it with the obstacle course’s explosive mines to propel himself toward the finish line 111.

Relationships

• All Might — Idol, teacher, and predecessor as One For All’s holder. Midoriya knows that All Might’s endurance is limited and repeatedly worries about him during battle. All Might brings him to I-Island as his invited companion 45 230 329 428.
• Jilan Jiyu — Friend and classmate who intervenes against Bakugo, heals Midoriya’s injured finger, and questions him out of concern about his Quirk. Jilan also challenges his reckless attempts to help when his body cannot safely support them 6 19 28 35 78.
• Katsuki Bakugo — Childhood classmate, admired rival, and frequent aggressor. Midoriya calls him “Kacchan” and wants to defeat him despite continuing to worry about his safety. They eventually cooperate against All Might during their final exam 28 89 230.
• Ochaco Uraraka — Close friend and frequent teammate. She supports his decision to help All Might, reassures him before facing Todoroki, and describes him as the first friend she made after moving to Tokyo 22 45 131 391.
• Tenya Iida — Classmate who initially scolds him during the entrance exam, then apologizes for underestimating him. Midoriya later saves him from Stain; Iida subsequently joins the Tokoyami rescue group to restrain its members from acting rashly 7 16 185 426.
• Shoto Todoroki — Sports Festival opponent whose refusal to use fire Midoriya challenges. They later fight Stain and join the plan to search for Tokoyami 131 133 188 426.
• Gran Torino — Mentor during the Work-Study Program 185 427.
• Tsuyu Asui — Classmate and rescue partner. Midoriya frees her during an exercise; she later rescues him from the ship after his confrontation with Amadeus Mask 82 94.
• Melissa — Support-equipment inventor who gives him the gauntlet he values above the other equipment available in I-Island’s storage room 346 347.
• Tomura Shigaraki — Enemy who holds him by the neck and threatens bystanders to force a conversation about Stain and All Might 234.

Story Role / Major Arcs

Entrance Exam and Early U.A. Training

Jilan first meets Midoriya outside U.A., stopping Bakugo from striking him. Midoriya thanks Jilan but insists that Bakugo’s hostility comes from concern about his admission prospects 6. During the practical exam, Midoriya defeats the giant robot, suffers extensive injuries, and receives sixty bonus points 12 24.

USJ Attack and Rescue Exercise

• At USJ, initially wants to help Aizawa fight, but accepts Jilan’s argument that the students should withdraw rather than become additional burdens 35.
• Survives Nomu’s attack after Jilan pushes him and Mineta underwater; Asui helps pull the group to safety 41.
• Warns All Might about the villains’ abilities and later rushes to intervene when he sees All Might in danger. Bakugo intercepts Kurogiri’s Warp Gate before Midoriya punches into it 45.
• During a later rescue exercise, blames himself for Kaminari’s apparent capture and goes to the flood-zone ship to save him 82 88.
• Correctly deduces that the crisis is a school exercise. He challenges Amadeus Mask’s bomb threat, remains aboard until the deadline, and is rescued by Asui when no explosion occurs 94 95.

U.A. Sports Festival

Hero Name, Stain, and Final Exams

• Chooses Deku as his hero name despite Kirishima warning that it can be read as “useless” 168.
• Interrupts Stain’s attempted killing of Iida and refuses an offer to leave with another injured hero while abandoning his classmate 185.
• Demonstrates his new whole-body enhancement against Stain, though a graze to his foot later leaves him immobilized 187 188.
• Faces All Might alongside Bakugo in the practical final exam. Their initial disagreement gives way to a coordinated explosion-and-escape plan, but All Might catches them and overwhelms both students 226 230.

Shigaraki’s Mall Encounter

• Shigaraki forces Midoriya to sit with him by threatening nearby civilians 234.
• Midoriya distinguishes Stain’s pursuit of ideals from Shigaraki’s destruction, helping Shigaraki identify All Might as the focus of his resentment 234.
• After Uraraka interrupts and Shigaraki releases him, Midoriya tells her to call the police and questions Shigaraki about All For One’s goal 234.

I-Island Crisis

• Accompanies All Might to I-Island and completes its robot-destruction attraction in sixteen seconds, just one second behind Bakugo 329 352.
• Uses Melissa’s gauntlet to breach the fiftieth-floor storage room and later helps the group pursue David while Melissa restores the security system 346 358.
• Expends the gauntlet’s final use trying to free All Might from a steel cage. The punch cracks the cage but fails to open it, and Jilan catches Midoriya as the recoil sends him away 363 364.
• Later reflects on the powerful attacks he used on I-Island and wonders when he will be able to reproduce that strength without outside assistance 391.

Forest Training Camp and Tokoyami Rescue Preparations

• Trains against Tiger to improve reaction speed and output control 402.
• During the League’s retreat, punches Dabi and pursues Magician to recover Tokoyami, but strikes a mud-like substitute as the abductors escape 417.
• Apologizes for failing to prevent the abduction and explains the circumstances of Tokoyami’s loss of control 417.
• Plans a search with Todoroki and Kirishima. The group departs with Yaoyorozu’s tracker, joined by Iida and Hagakure as restraints against reckless action; Jilan follows in disguise 426.
