Bomb (ボンブ, Bonbu) is Bang's older brother as well as a dojo master.


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 martial arts robes, while Bang has a plain black shirt with white pants. He's quite tall considering his age and unlike most elderly figures he has a very strong posture, unlike Bang who is shorter than Bomb is and often slouches when he's walking.


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

Abilities and PowersEdit

Not much is known about Bomb's strength. However, 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. He was able to effortlessly shred a monster to pieces, further hinting at his superior strength. However, he was knocked out by a Black Sperm clone with only a single hit, albeit this was while he was caught off guard.

Fighting StyleEdit

Whirlwind Iron Cutting Fist (旋風鉄斬拳, Senpū Tetsuzan-ken): Bomb's martial art. This martial art style involves a powerful hand rotation technique to create a razor sharp whirlwind pressure that chops the opponent into tiny pieces.[4] The martial art then pushes the opponent back with various degrees of force depending on the proximity towards the eye of the whirlwind.[5]

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. 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.[6]
  • 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.
