One-Punch Man Wiki

Heavy Kong (ヘビィコング, Hebī Kongu) is an A-Class professional hero for the Hero Association who was previously ranked 34. He is in charge of W-City.


Heavy Kong is a very muscular and tall man with a bald head, large lips and a wide nose. He has a black beard, that starts from the top of his jaw line and follows through completely, ending in a chin strip. He also has two earrings. His arms are wide and wears two metal armbands on both his arms, around his wrist and biceps. He drapes a cloth around his left shoulder, covering half of his torso, held together at his waist by a championship belt with "KONG" written on it. He also has a black metal chain hanging from his other shoulder.

Abilities and Powers[]

As an A-Class hero, Heavy King is a skilled and powerful fighter. As he is in charge of a city, the Hero Association most likely trusts in his abilities.

Fighting Style[]

Hand-to-Hand Combatant: Heavy Kong seems to prefer unarmed combat, as seen during his fight against Marshall Gorilla. Despite the latter being an armed Tiger level monster, Heavy Kong suffered only one wound to the arm after fighting him on his own for 15 minutes, implying he has a decent level of skill.


Forearm Guards: Heavy Kong's metal bracelets are durable enough to resist a knife slash from a Tiger level monster with only a nick.
