Personality

The brothers billed themselves as the union of the sharpest mind and the mightiest body, and they aimed that combination squarely at seizing control of the world.

History

After Fukegao concocted a steroid he named Biceps Brachii King, Marugori swallowed it and mutated into a giant, and together the siblings rampaged through D-City in the name of conquest. Saitama soon turned up perched on Marugori's shoulder; when Fukegao ordered his brother to swat the intruder, Marugori struck the wrong shoulder and crushed Fukegao by mistake. Saitama then put down Marugori, whose collapse caused damage to neighboring B-City. Both brothers died in the incident, ending their short-lived team.
