Explosion ( (ばく) () Bakuha?) is the Quirk used by Katsuki Bakugo.


Explosion allows the user to excrete nitroglycerin-like sweat from their palms and ignite it at will to create explosions of various sizes.

Katsuki using Explosion's brightness to subdue Fumikage Tokoyami and Dark Shadow.

Through either one of his palms, Katsuki creates fiery shock waves that are highly powerful and destructive, often burning and/or shattering whatever they hit, with Katsuki himself being immune to them, save for some recoil. Because this Quirk generates light, it's a natural counter to Dark Shadow, which thrives in the dark.

The more Katsuki sweats, the more powerful the explosions become.[1] This essentially means that Katsuki's blast gradually grows in power the longer he combats since he will naturally sweat more through ongoing physical activity.


During cold weather, the nitroglycerin-like sweat requires a slightly longer time to detonate, as opposed to warm weather, where conditions are optimal for ignition.

Repeated explosions, particularly large ones, eventually result in throbbing pain to Katsuki's arms and shoulders.[2][3] Additionally, creating explosions with both arms at the same time causes their overall strength to disperse between both limbs, leading to individually weaker blasts.

Due to him being limited to producing explosions from only his hands, which are also where his Quirk Factor is, Katsuki will be unable to utilize his Quirk if he loses the said limbs.


Katsuki intimidating Izuku with his Quirk.

Katsuki is very proud of his Quirk. Throughout his life, people frequently commended Explosion, leading Katsuki to develop unrealistic expectations of himself, which he wasn't able to live up to. As a result, he acted arrogant and condescending to others to cope with his painful feelings of inferiority. Before getting into U.A. High School, Katsuki had the habit of using Explosion as a means of threatening and bullying Izuku Midoriya, and while he has dropped that practice for the most part in the present, he still likes to use his Quirk to intimidate foes during fights, usually by creating miniature explosions around both his palms.

Katsuki using Explosion for speeding up, dodging, slowing down and attacking.

Katsuki is able to use Explosion to propel himself through mid-air, blind opponents, and release long-range blasts, among other applications. Explosion is a versatile Quirk, especially for battle situations as the recoil caused by the blasts can be exploited for mobility purposes. When coupled with his fighting talent and intelligence, Katsuki can come up with new moves with little difficulty, even having a few ready by the time he started U.A. High School's school year. Thanks to Katsuki's battle ingenuity and natural aggression, Explosion tends to be a very overwhelming Quirk for others to face off against.

In battle, Katsuki prefers all-out offense, using his Quirk's propulsive abilities to close the distance between him and his opponents, followed by a bombardment of close-range attacks that are often started with a powerful right hook. Despite having great mastery over his Quirk, Katsuki tends to recklessly cause unnecessary damage to his surroundings, which is a common issue with hero work, as it may jeopardize missions that require more careful approaches.

As mentioned by Katsuki himself, the Grenadier Bracers from his costume serve to reduce the risk of physical strain caused by overusing his Quirk.[3] These bracers store part of his explosive sweat, with Katsuki being capable of igniting all of it at once by triggering one of the bracers' firing pins, releasing a massive blast that, while devastating, tolls the shoulder of whoever uses it, although Katsuki seems to be completely unfazed by this due to his superior physical ability. Katsuki also carries around grenade-like containers that can be filled with his sweat, allowing him or someone else to use them as actual explosives.

Named Super Moves

Explosive Speed.gif Explosive Speed ( (ばく) (そく) ターボ Bakusoku Tābo?): Katsuki throws his hands back and then causes an explosion in his palms to propel himself forward. This move can also be used to achieve a pseudo form of flight, as Katsuki used this move to fly over the giant robots during the Obstacle Race during the U.A. Sports Festival.
Stun Grenade.gif Stun Grenade (閃光弾 (スタングレネード) Sutan Gurenēdo?): Katsuki creates a sphere of light with his hands. The sphere of light implodes, causing an explosion around Katsuki, blinding anything in Katsuki's vicinity.[4]
Point-Blank Stun Grenade (ゼロ (きょ) () 閃光弾 (スタングレネード) Zero Kyori Sutan Gurenēdo?): A variation where Katsuki fires off his Stun Grenade at point-blank range of the opponent to immediately stun and immobilize them with little lasting damage. This variation was first used against Setsuna in the fourth round of the Joint Training Battle. Point-Blank Stun Grenade.gif
Howitzer Impact.gif Howitzer Impact (榴弾砲着弾 (ハウザーインパクト) Hauzā Inpakuto?): Katsuki dashes into the air and creates two Explosions in his hands. While in the air, Katsuki spins himself around, building up momentum for his Explosions. After spinning himself around and gathering momentum for his Explosions, Katsuki fires an Explosive tornado at his opponent.[5]
AP Shot.gif AP Shot (徹甲弾 (A・P・ショット) Ē-Pī Shotto?, literal meaning "Armor-Piercing Shot"): Katsuki stretches out one of his hands and uses his other hand to form a circle on the palm of his outstretched hand. By focusing his the path of his explosions into a single point instead of around his whole palm, Katsuki creates a concentrated blast with reduced area of impact, but with enough power to successfully pierce even solid concrete.[6]
AP Shot: Auto-Cannon (徹甲弾 (A・P・ショット) 機関銃 (オートカノン) Ē-Pī Shotto Ōtokanon?, literal meaning "Armor-Piercing Shot: Autocannon"): A scattershot version of his AP Shot technique, the explosion power is reduced in order to avoid dealing severe damage to human targets.[7] AP Shot Auto-Cannon.gif
AP Machine-Gun (徹甲機銃 ((A・P・マシンガン) Ē-Pī Mashingan?): A stronger version of his AP Shot: Auto-Cannon where Bakugo fires larger, rapid fire explosions. This technique was first used against Tomura Shigaraki in the Paranormal Liberation War Arc. AP Machine-Gun.png
Explode-A-Pult.gif Explode-A-Pult (爆破式 (エクス) カタパルト Ekusu Kataparuto?): While in mid-air, Katsuki grabs an opponent with one of his arms, then fires an explosion with his free arm, causing both him and his opponent to spin. Katsuki then forcefully throws his opponent with the aid of a second explosion. He first used this technique against Togaru Kamakiri in the fourth round of the Joint Training Battle.[8]
Land Mine Blast.png Land Mine Blast ( (ばく) (ふう) () (らい) Bakufū Jirai?): Katsuki places his Grenadier Bracer on the ground and lets of a massive explosion into the ground, blowing back any obstacles surrounding him. This technique was first used to dissipate Mahoro Shimano's Hologram,[9] and later used to dispel Izuku Midoriya's Smokescreen.[10]
Blasting Speed Turbo Cluster.png Cluster (クラスター Kurasutā?): Katsuki positions his hands backwards, using explosions to quickly propel him forward, only this time, he condenses them to become stronger and faster, resulting in a flurry of bursts that blast him forward at incredible speeds.[11] This technique was first used during the Paranormal Liberation War to save Izuku from Tomura's Rivet Stab attack,[12] and used it again to assist the Heroes against the Near High-End Nomus.[11] He later used this ability in a group effort to retrieve Izuku.[13]
