Explosion: Katsuki Bakugo’s Quirk in My Hero Academia explained

My Hero Academia (Boku no Hero Academia) features a lot of relevant characters propelling its narrative. One of the series’ standout characters is Katsuki Bakugo, a fiercely competitive and confident young hero-in-training. 

Let’s dive deep into Bakugo’s unique Quirk, its abilities, limitations, and how it shapes his character within the story.

The Basics 

Bakugo’s Quirk is named “Explosion”. At its core, this Quirk allows him to secrete a nitroglycerin-like sweat from his palms and ignite it at will, causing powerful explosions.

The more he sweats, the stronger the potential explosion, which makes him particularly formidable in prolonged battles or under hot conditions.


Blasts: The most straightforward application of his Quirk is releasing explosive blasts. Depending on the amount of sweat and force he applies, these can range from minor detonations to large-scale, landscape-altering explosions.

He often uses this ability both offensively, to attack opponents, and defensively, to deflect incoming attacks or create smoke screens.

Propulsion: One of the more innovative ways he uses his Quirk is for movement. By detonating his explosions behind him, he can propel himself at high speeds in the air, essentially granting him a form of flight.

This ability, which he calls “Blast-Off”, allows him to quickly close distances or dodge attacks.

Concussive Force: Beyond the fiery nature of his explosions, the concussive force they produce can be just as deadly. Even if an opponent isn’t directly hit by the explosion’s flames, the sheer impact can incapacitate or heavily injure them.


Over time, Bakugo has honed his Quirk and developed several specialized techniques, showcasing his tactical prowess:

Stun Grenade: By creating a circular motion with his hands, Bakugo can release a blinding light without a loud bang. This is useful for disorienting opponents without causing extensive damage.

AP Shot: Short for “Armor-Piercing Shot”, this technique focuses his explosive power into a concentrated beam, allowing him to target specific areas or penetrate through tough defenses.

Howitzer Impact: A high-powered, spinning move where Bakugo releases a massive explosion upon landing, dealing immense damage to everything in its vicinity.

Limitations and Vulnerabilities

While Bakugo’s Quirk is undoubtedly powerful, it is not without its limitations:

Sweat Dependency: The power of Bakugo’s explosions correlates with the amount of sweat he can produce. In colder environments or situations where he’s not sweating as much, his explosions may be weaker.

Physical Strain: Using his Quirk extensively can be taxing on Bakugo’s body. Overusing it could lead to exhaustion or even injury.

Unpredictability: Larger explosions can sometimes be less controlled, posing risks not only to opponents but also to Bakugo himself and his allies.

Character Implications

Bakugo’s explosive power is an extension of his personality. He is hot-headed, aggressive, and often volatile, much like his Quirk. 

However, as the series progresses, viewers witness Bakugo’s growth, not just in mastering his Quirk, but in tempering his personality. He begins to understand the value of teamwork, strategy, and even humility. 

Beyond the sheer might of Katsuki Bakugo’s detonations, it’s his inventive applications, combined with his evolving character arc, that make him a captivating figure in the series.
