One-Punch Man Wiki
I am the strongest.
— Marugori after taking Biceps Brachii King[1]

Marugori (マルゴリ, Marugori), also called Beefcake, was a human who drank the Biceps Brachii King steroid developed by Fukegao, which turned him into a mutated giant. He was killed by Saitama.[4]


As a human, Marugori was depicted as a buff young man, with a large torso and muscular arms. He had sharp eyes and a shaved head. He wore a simple tank top and plain jeans. These clothes were ripped off when he transformed into a Mysterious Being. When transforming, his veins were popping, muscles expanding and his size grew incredibly. As a giant, he resembled a giant human body without skin, steaming, with a white, bone-like armor covering his enormous muscles. Most of his skeleton and muscle tissue became visible, including his tendons. He also grew two tubes, protruding from his chest and running over his shoulders to his back.


Marugori was a very straightforward individual who was loyal to his brother and had a strong desire to become stronger. Despite the callousness he displayed while murdering thousands of people, he was truly saddened and enraged by the loss of his brother.


Introduction Saga[]

Saitama Introduction Arc[]

Marugori destroys D-City

Marugori is first seen in the lab of his scientist older brother, Fukegao. He is handed the ultimate steroid, Biceps Brachii King and drinks it, being told that it will give him the power he always wanted. Marugori yells out in pain and his body grows in size at a rapid rate. It doesn't take long before he bursts through the lab's ceiling and transforms into a severely mutated giant. He picks up his brother, puts him on his shoulder and marches for the nearby D-City. Arriving at the city, he thinks to himself that he always dreamed of becoming the world's strongest man. He swings his arm and crushes a few buildings. His brother is ecstatic about his overwhelming strength and the brothers move on to the next city.[5]

Saitama kills Marugori with a punch

As Marugori heads to B-City his brother notices someone is sitting on the shoulder opposite to the one he is sitting. His brother yells, telling Marugori to kill him. Marugori swats at the wrong shoulder and kills Fukegao by accident. In his ensuing rage Marugori grabs Saitama and throws him to the ground. Saitama starts to get up, but Marugori jumps onto him and starts to punch Saitama repeatedly, leaving a giant hole in the ground. Believing himself victorious, Marugori begins to mourn for his brother until Saitama jumps out of the hole and punches him in the face, killing him and sending him crashing onto B-City, destroying it.[6]

Abilities and Powers[]

After taking the drug Biceps Brachii King, Marugori gained massive strength and size, becoming one of the largest monsters in the series. Marugori was classified as a Demon-level threat and would have been upgraded to Dragon if it were not for Saitama stopping him.[3]

Physical Abilities[]

A demonstration of Marugori's strength

Immense Strength: Due to his massive size after mutating into a giant, Marugori possessed enormous physical strength. This was demonstrated when he generated powerful shockwaves from one of his blows to cause massive damage to an entire city. He also wielded outstanding leg strength, shown when he was able to create a large crater by stomping at the ground.[7] The hole he created by punching Saitama was 100 meters wide.[2]

Enhanced Speed: Despite his size, Marugori was able to deliver high-speed combos in a matter of seconds.

Fighting Style[]

Hand-to-Hand Combatant: Marugori appeared to only rely on his brute strength and colossal size after taking the Biceps Brachii King from his older brother, meaning he had no real martial arts experience or fighting technique.

  • Barrage of Armed Hits (豪腕の連打, Gōwan no renda): Marugori throws a barrage of punches into a concentrated point.[2]
  • Trampling (ふみつけ, Fumitsuke): Marugori stomps the ground.[2]
