Power Progression

Stage / Realm / Level Chapter Notes
Enrollment benchmark 17 399 Propels a softball approximately 705 meters with Explosion; the original measurement is later specified as 705.2 meters. His middle-school throw without Quirk use was 67 meters.
Equipment-free cannon blast demonstrated 129 Reproduces his gauntlet-assisted cannon attack without equipment, destroying Uraraka’s suspended rubble. Explains that the storage devices reduce the strain of such attacks rather than make them possible.
Howitzer Impact: Big Bang 140 Combines explosive propulsion, aerial rotation, and a charged blast at several times its usual power. Collapses from exhaustion after using it against Jilan.
Mountain-camp benchmark 399 Throws the softball 709.6 meters, only 4.4 meters farther than at enrollment. Aizawa uses the small improvement to demonstrate the need for dedicated Quirk training.
Sweat-gland conditioning 400 405 Repeatedly immerses his hands in hot water before firing explosions, training to increase their scale.
Full-body detonation used in combat 410 Detonates sweat across his entire body while trapped in Muscular’s grip. The attack breaks through the surrounding muscle but burns Bakugo extensively.

Background

Bakugo and Izuku Midoriya have been classmates since kindergarten. According to Midoriya, Bakugo could easily accomplish things other children could not and grew up surrounded by praise. This encouraged his belief that he was stronger than everyone else and should never need another person’s help 28.

During his third year of middle school, Bakugo was trapped by the Sludge Villain. He resisted for more than ten minutes while the responding Pro Heroes struggled to intervene, before All Might rescued him. Although the incident brought him public praise, Midoriya describes it as a lasting source of shame for Bakugo because he had been helpless and dependent on rescue 28 104.

Appearance

Bakugo has blond, sharply spiked hair and a fierce expression; his school uniform is initially worn loosely 12 16.

  • Combat costume: A sleeveless top, a partial eye mask, oversized green grenade-shaped arm equipment, and pointed headgear behind his hair 21.
  • Subway-pursuit appearance: A red-and-black sleeveless jacket, large grenade-shaped arm armor, black winglike head plates, and blond hair flattened with gel 207.
  • After the mountain attack: Bandaged from head to toe, with only his face exposed 422.

Personality

Bakugo is aggressive, profane, and intensely competitive. He treats Jilan’s lack of interest in winning as incompatible with becoming a hero, and openly declares his ambition to surpass All Might and become number one. His pride also makes him reject assistance, even when injured or when another person is better suited to a task 20 81 353 410.

His hostility does not mean he fights without thought. Entrance-exam evaluators describe him as bold but careful, with impressive combat skills. Aizawa likewise defends his relentless attacks against Uraraka as caution toward a capable opponent rather than contempt for her 12 129. However, his pursuit of dominance can overshadow rescue work: he receives no entrance-exam bonus points after using endangered examinees as distractions instead of helping them 12.

Despite his violent threats, Bakugo hesitates when an action would certainly kill the Nomu. His protection of Kota later challenges his belief that strength is chiefly something to display. After fighting Muscular, he acknowledges Kota’s parents as worthy Pro Heroes; afterward, he privately recognizes that his own failure to relay information contributed to the students’ difficulties 46 410 422.

Abilities & Skills

Explosion

Bakugo’s sweat glands produce a nitroglycerin-like substance that he can detonate. He normally uses his palms, but his battle with Muscular establishes that sweat elsewhere on his body is also explosive 140 410.

  • Increasing output: Longer fights produce more sweat, allowing stronger explosions as the battle continues 140.
  • Close-range offense: Combines palm explosions with punches, kicks, grabs, and rapid changes of position 23 85.
  • Large-area destruction: Can destroy building walls and shatter large quantities of arena debris 23 129.
  • Explosion resistance: His skin withstands explosions well enough for him to remain conscious after a full-body detonation, though he still suffers extensive burns 410.

Explosive Mobility

Bakugo directs blasts behind or beneath himself to accelerate, evade attacks, and maneuver through the air 18 23 409.

  • Completes the 50-meter dash in 4.13 seconds using explosive propulsion 18.
  • Maintains flight above the Sports Festival minefield instead of crossing it on foot 109.
  • Adjusts his position and rotation in midair during Howitzer Impact: Big Bang 140.
  • Uses a downward blast to rise above Muscular’s punch and attempt a close-range counterattack 409.

Combat Analysis and Reflexes

Bakugo can identify weaknesses and adapt quickly despite his confrontational behavior 12 46.

  • Weak-point detection: Deduces that Kurogiri has a vulnerable physical section beneath his mist and targets the conspicuous neck armor 45 46.
  • Rapid counters: Turns and blasts Uraraka away just before she can touch him, including when she attacks through smoke 129.
  • Matchup exploitation: Forces Tokoyami to surrender by repeatedly exposing Dark Shadow to explosive flashes 139.
  • Team planning: Uses himself as a distraction while Midoriya attacks All Might from behind with a borrowed gauntlet 230.

Major Techniques

Technique Function Limitation / Result
Stored-sweat cannon blast Releases accumulated explosive material from a grenade-shaped gauntlet 23 129. Powerful enough to destroy an outer building wall; All Might threatens to end the training match if Bakugo repeats it 23.
Equipment-free cannon blast Produces a comparable cannon-like attack directly from his hand 129. Places strain on his body that the storage equipment is intended to avoid 129.
Howitzer Impact: Big Bang Uses aerial rotation and propulsion to deliver a greatly amplified blast at close range 140. Leaves him exhausted and unable to remain standing 140.
Point-blank stun grenade Briefly blinds All Might so Bakugo can escape his hold 230. Creates an opening, but does not overcome All Might’s strength 230.
Full-body detonation Explodes accumulated sweat across his body while enclosed by Muscular’s muscle fibers 410. Burns Bakugo and incapacitates Muscular only temporarily 410.

Weaknesses

  • Cold: Todoroki’s ice cools Bakugo’s hands and freezes his sweat glands, interrupting his airborne advance 109.
  • Sweat removal: The Hero Killer copycat’s slime absorbs his palm sweat and prevents immediate explosive pursuit 207.
  • Water: Kota washes away accumulated sweat and extinguishes a prepared attack, although Bakugo soon generates another explosion 404.
  • Collateral damage: Bakugo limits his attack in the subway because a full-power blast could cause severe damage 207.
  • Physical limits: Prolonged use requires rest, while powerful attacks can exhaust or injure him 140 405 410.

Equipment

  • Grenade-shaped gauntlets — Store sweat for powerful blasts while reducing bodily strain; their heavy casings can also serve as blunt weapons. Midoriya uses one during their examination against All Might 23 129 230.
  • Combat mask and pointed headgear — Distinctive parts of his hero costume 21.
  • Training radio, floor plan, and capture tape — Issued for the indoor combat exercise to support communication, navigation, and opponent capture 23.

Relationships

  • Izuku Midoriya — Childhood classmate and rival, whom Bakugo calls “Deku” and describes as his punching bag. Midoriya admires him but intends to defeat him. Bakugo later admits that he resents Midoriya for offering advice and acting independently when he believes Midoriya should be his subordinate 20 28 404.
  • Jilan Jiyu — Classmate and rival. Their conflict begins when Jilan intervenes in Bakugo’s confrontation with Midoriya, then intensifies over entrance-exam rankings and the Sports Festival final. Jilan repeatedly challenges Bakugo’s attitude toward friendship and strength 6 16 140 404.
  • Eijiro Kirishima — Friend and frequent companion in combat and social situations. Bakugo calls him over during a holiday and brings him to the I-Island party; Kirishima later defends him when Kaminari laughs at his bandages 35 156 352 422.
  • All Might — Idol, rescuer, teacher, and the standard Bakugo wants to surpass. Bakugo is shaken by the possibility that he might have seriously injured All Might during a disguised training exercise 28 81 95.
  • Shoto Todoroki — Respected competitor whom Bakugo nicknames “half-face.” They clash during the obstacle race and even compete over the cooking fire at camp 20 109 403.
  • Kota — Initially the target of Bakugo’s harsh provocations about courage and Quirks. Their relationship becomes a declared rivalry, and Bakugo risks his life protecting him from Muscular 403 404 409 410.
  • Mitsuki Bakugo — Mother. Exchanges insults with him, teases him about the Sports Festival, and urges him to settle his frustrations through a future rematch 156.
  • Masaru Bakugo — Father; Mitsuki left her biker-gang life after marrying him 156.
  • Shota Aizawa — Homeroom teacher. Restrains Bakugo when he charges Midoriya, recognizes his tactical caution, and designs his mountain-camp training 19 129 400.

Story Role / Major Arcs

Entrance Exam and First Classes

Bakugo introduces himself by threatening Jilan after Jilan intervenes in his confrontation with Midoriya. During the entrance exam, his efficient destruction of robots earns praise for his combat ability, but his failure to rescue others earns him zero bonus points. He leads the practical-combat results, while Jilan takes first overall 6 12 16 17.

At U.A., Bakugo’s disbelief at Midoriya possessing a Quirk leads him to charge his former classmate, forcing Aizawa to restrain him. In the indoor combat exercise, he leaves Iida defending the objective and pursues Midoriya with increasingly destructive attacks. Midoriya and Uraraka ultimately win, leaving Bakugo visibly shaken 19 22 23 24.

USJ Attack

Bakugo and Kirishima initially attack Kurogiri but fail to stop his mist. After fighting through the collapse zone, Bakugo returns to the central battle, interrupts Kurogiri’s portal, and pins him by his vulnerable neck armor 35 44 45.

He cannot bring himself to force a portal closure that would kill the Nomu. Later, he pulls Kaminari out of a bullet’s path as the confrontation ends and U.A.’s reinforcements arrive 46 47.

Rescue Exercise

Bakugo rejects Midoriya’s proposed search plan and searches from the air, damaging the unstable surroundings with his explosions. When an apparent villain appears carrying Todoroki, Bakugo attacks and urges Iida to find Midoriya 81 85 86.

He insists on fighting the opponent alone despite being outmatched. After the exercise reveals the opponent to be All Might, Bakugo angrily objects to the danger of the deception, then immediately brightens when All Might praises his performance 88 89 95.

Sports Festival

Bakugo declares that he will win regardless of his opponent. He contests the obstacle-race lead with Todoroki and retaliates against Class B after Monoma steals his cavalry-battle headband and mocks the Sludge Incident 102 109 117 120.

In the tournament, he defeats Uraraka by countering her approaches and destroying her floating-debris trap. He later forces Tokoyami’s surrender through repeated flashes before facing Jilan in the final. Pressured by Jilan’s Hamon Spring Punch, he unleashes Howitzer Impact: Big Bang and collapses from exhaustion. A later chapter identifies Bakugo as the Sports Festival champion 129 131 139 140 352.

Subway Pursuit and Final Examination

Bakugo pursues a Hero Killer copycat into a subway station but is hindered by blood-based slime that absorbs his sweat. Jilan stops the fleeing criminal. Bakugo’s supervising Pro Hero reprimands him for disobeying orders, and Bakugo reluctantly thanks Jilan 207 208.

Paired with Midoriya against All Might, Bakugo initially refuses cooperation. He eventually devises a joint gauntlet attack, though All Might catches them before they reach the exit. The exam overview lists only Kirishima–Aoyama and Ashido–Kaminari as failing groups, placing Bakugo and Midoriya among those who pass 230.

I-Island Incident

Invited to a party as Sports Festival champion, Bakugo brings Kirishima but gets lost without a phone. Beforehand, he completes an island robot challenge in 15 seconds, narrowly ahead of Midoriya’s 16 seconds. The pair encounter their classmates in an elevator and learn that terrorists have seized the venue 352.

Mountain Training Camp

Bakugo pushes through the forest test without taking the rest breaks used by his classmates. At camp, Aizawa exposes the limited growth in his raw throwing output and assigns hot-water conditioning followed by repeated explosions 399 400.

Bakugo brings Kota food, then provokes him into using his rejected Quirk and declaring that he will become stronger. Jilan subsequently challenges Bakugo to treat his own power as a source of pride rather than merely a means of showing off 403 404.

During the villain attack, Bakugo protects Kota from Muscular and refuses an invitation to join the League of Villains. He learns that Tokoyami is the intended target but cannot immediately relay the warning. After his full-body explosion fails to keep Muscular down, he prepares to remain behind while Kota escapes 409 410.

An explosive toy car ultimately incapacitates Muscular, allowing them to escape. Aizawa escorts Bakugo and Kota back to base, where Bakugo loses consciousness. Recovery Girl’s treatment regrows his damaged skin overnight; he later privately accepts some responsibility for not delivering the warning about Tokoyami sooner 422.
