Abilities and Powers
Bomb and Bang are the two greatest masters of martial arts world. It has been stated by Murata that Bomb is stronger than Bang. 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. 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.

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.

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. 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.

Fighting Style


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.
 * 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. The martial art then pushes the opponent back with various degrees of force depending on the proximity towards the eye of the whirlwind. The cylindrical pressure is also used in the martial art's kicks and is sharp enough to cut through concrete.
 * Whirlwind Water Stream Blasting Sky Splitting 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.
 * 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 Blasting Sky Splitting Fist. Both perform extremely powerful strikes at their opponent with their respective martial arts during combat.
