Bomb (ボンブ, Bonbu) is Bang's older brother as well as a dojo master. He and Bang are the two greatest masters of martial arts world.[2]


Bomb, like his brother, Bang, is an aged-but-muscular individual. Appearance-wise, he is almost opposite to his younger brother. While Bang still has his hair and sports a short mustache, Bomb has a long beard and white, long hair with the top of his head being bald. He wears a classic-style green on blue martial arts robes, while Bang has a plain black shirt with white pants. He is slightly taller than Bang and he has a very strong posture, unlike Bang who often slouches when he's walking.


Bomb is a caring older brother to Bang. He also seems to be bit angry for having to dismiss all of his disciples, but is quite understanding as he believes there's a reason for letting his disciples go.

He also aware of the fact he is no longer young anymore and his prime has passed in which he laments that how old he is when he has to carry all the unconscious bodies of defeated heroes to run to safety before running out of stamina.

Bomb and Bang arrive at the scene

Bomb is first seen in his dojo in a meeting with his brother, Bang. Although he doesn't know Garou himself, he talks about how he heard that he's a threat and must be taken down. Therefore he prepared to close his dojo and say farewell to his students for their own safety. He agrees on hunting him down alongside Bang after a short conversation.[3] He later arrives with Bang to a scene where Garou badly defeats the Tank Topper Army, Mumen Rider and Charanko.[4]

Monster Association Arc Edit

After Bang and Bomb arrive at the fight between Garou and Genos, he helps his brother dispose a monster nearby by using his Whirlwind Iron Cutting Fist technique to mince a monster into pieces.

When Bang prepares to fight Garou, Bomb states that he will take care of the rest of the monsters. After clearing the majority of monsters, he appears in front of Garou and kicks him in the face to prevent him using Death Gatling's body as meat shield. Soon after, both brothers combine their martial arts against Garou.[6] As they were about to land the finishing blow, Garou surprises them with Tanktop Master's Tanktop Blow and grabs a huge tree during swings at both Bomb and Bang forcing them to back off.[7] Bang tells Garou to surrender, but was surprised when Phoenix Man came and took Garou, while calling Elder Centipede to cover their escape. He and his brother save the unconscious heroes from their demise.[8]

Bomb combines his strength with Bang and Genos and managed to significantly damage Elder Centipede, however the monster's regenerating and molting abilities only cause it to become larger, stronger and angrier. Furthermore, Genos's plan to destroy the monster from the inside failed.[9] The trio decide to retreat, but as they were getting closer to the edge of the forest Bang decided to sacrifice himself to buy time for Bomb to escape with the unconscious heroes and Genos. Fortunately, King arrives and catches Elder Centipede's attention by tricking him into believing that he brought Blast with him, as well as taunting the monster, making the monster charge toward the S-Class hero.[10]

Abilities and PowersEdit

It has been stated by Murata that Bomb is stronger than Bang.[11] As Bang's older brother and master of the Whirlwind Iron Cutting Fist, it is safe to say that Bomb's strength is on par with the S-Class heroes, even possibly surpassing some of them. However, he was knocked out by a Black Sperm clone with only a single hit, albeit this was while he was caught off guard, hinting that if he was on guard then he might have able to endure Black Sperm's attack easily. It is revealed that 60 years ago, Bomb can handle massive lethal injuries like Garou.[12] In the present, Bomb has passed his prime and he states that he does not have the stamina to carry multiple unconscious bodies for too long, especially after using a grand technique like Whirlwind Water Stream Blasting Sky Splitting Fist.[13][14]

Physical AbilitiesEdit

Immense Strength: As a master martial artist in the same regards as his younger brother, Bang, Bomb possesses incredible superhuman strength, being able to shred Mysterious Beings into pieces with his hands alone. Combining his strength with his brother, Bang, Bomb was able to damage Elder Centipede’s initial carapace armor which was able to withstand Metal Knight’s missiles and Metal Bat’s swing and send the enormous monster back.

Immense Durability: According to Bomb himself, he has a lot of durability, which enables him to endure massive damage and still standing. However, he states that he does not have the the same durability he used to have 60 years ago. Despite being knocked back by Elder Centipede, he and Bang took minimal damage.[15]

Immense Speed and Reflexes: Bomb has incredible speed as in a split second he shredded a monster into pieces with his hands in a circular motion before it could even react.[16] The speed of his attacks are so fast that the monster's body had take a few moments to fall apart after Bomb completed his attack on it. Moreover, he was quick enough to protect unconcious A-Class heroes from falling debris created by Elder Centipede.[17]

Fighting StyleEdit

Whirlwind Iron Cutting Fist

Bomb performs the Whirlwind Iron Cutting Fist to shred a monster to pieces.

Master Martial Artist: As Bang's older brother and a dojo master himself, Bomb possesses great mastery over martial arts as like his younger brother, he invented his own unique style and techniques from decades of martial arts training. A testament of his skills and strength is that Bang came to him for help in stopping Garou when his former disciple began hunting heroes. Garou himself acknowledges Bomb’s prowess to being the greatest in the world rivaled only by his brother, Bang, himself.

  • Whirlwind Iron Cutting Fist (旋風鉄斬拳, Senpū Tetsuzan-ken): Bomb's martial art. Whirlwind Iron Cutting Fist revolves around manipulating the air. This martial art style involves a powerful hand rotation technique to create a razor sharp whirlwind pressure that chops the opponent into tiny pieces.[18] The martial art then pushes the opponent back with various degrees of force depending on the proximity towards the eye of the whirlwind.[19] The cutting pressure is also used in the martial art's kicks and is sharp enough to cut through stone.[20] His fists are flexed differently for more direct attacks, with the first knuckles being extended, similar to leopard fist, implying that the Whirlwind Iron Cutting Fist parallels real-life Leopard Kung Fu.
  • Bang and Bomb combine their fist to perform the Whirlwind Water Stream Roaring Aura Sky Ripping Fist.
  • Bang and Bomb combine their fist to perform the Whirlwind Water Stream Roaring Aura Sky Ripping Fist.
  • Whirlwind Water Stream Roaring Aura Sky Ripping Fist (旋風流水 轟気空裂拳, Senpū Ryūsui Gōki Kūretsu-ken): A advanced technique than combining both Whirlwind Iron Cutting Fist and Water Stream Rock Smashing Fist. In order to perform the technique, both Bang and Bomb stand together side-by-side and rotating both one of each of their hands into one fist and unleashing the massive wave of air streams that resembles their respective martial arts (flowing air wave for the Water Stream Rock Smashing Fist and whirlwind air wave for the Whirlwind Iron Cutting Fist) toward an opponent with their fists standing side-by-side. The technique is powerful enough to knock back Elder Centipede during its rush towards them and causes the monster's carapace to become brittle from the shockwave of the air streams. However, it is stated by both Bang and Bomb, they can only do this technique once in an occasion since both of them have passed their prime.[21] Traditionally when the technique connects, the shockwaves created will spread through the victim's entire body, which ultimately reduces the victim to dust.[22]
    • Secret Combination: Cross Fang Dragon Slayer Fist (連携奧義 交牙竜殺拳, Renkei Ōgi: Kōga Ryūsatsu-ken): A combination of the martial arts of Bomb and Bang, even more powerful than Whirlwind Water Stream Roaring Aura Sky Ripping Fist. Both perform extremely powerful strikes at their opponent with their respective martial arts during combat.


Bang's students

Bomb cameo

  • Bomb made a cameo appearance in an OVA, standing behind Bang's students.[23]
  • Bomb's fighting style can be considered to based on the Nanto Sei Ken martial art from the Fist of the North Star series since it involves cutting opponents into pieces with bare hands. In detail, Bomb's style is based on the character Huey, who uses the Gosha Fūretsu Ken (五車風裂拳, Five Chariots Wind Split Fist) to shred an opponent into pieces using wind pressure.
  • According to Murata, Bomb is even stronger than Bang.[24]
