OPM Manga Chapter 3 starts with a scientist named “Oldface” experimenting on a drug that enhances muscle power. He gave his experimental steroids, known as the “Biceps King”, to his body-building brother, Beefcake, who wants to become the strongest….
After drinking one test tube of the drug, Beefcake becomes a giant taller than mountains with considerable strength. His body is covered in thick muscles, too, almost like the armored titan in AOT.
He then picks up his scientist brother and puts him on his shoulder, forming the team, “the brains and the brawns”. They plan on conquering the world and reigning as kings!
Panic ensued in the city as the giant monster started destroying buildings that looked like miniature toys to him due to his overwhelming size. In just one swing of his fist, the whole city was annihilated.
The next city panicked as the giant started approaching them. Disaster Level Demon was then raised, and evacuation started in B-City ASAP.
As the scientist’s brother was celebrating, he was surprised that another person was on the other shoulder of his brother. this time, it was our hero, the caped baldy!
The giant immediately tapped his right shoulder but began panicking after realizing he crushed his scientist brother. Because of this, he grabbed the caped hero, threw him on the ground, and stepped on him with all his anger and might.
After leaving a huge hole in the ground, he realized he felt empty even after becoming the strongest.
Our hero suddenly bounced back from the huge hole and delivered a normal punch, hitting the face of the giant, thereby crushing his jaws and knocking him down to the ground.
The ground where he got knocked out was B-City, which was completely annihilated.
