Oldface
Oldface was a brilliant scientist best known for creating the Biceps Brachii King steroid, an experimental drug that transformed his brother into the massive, hulking creature known as Beefcake. The formula worked exactly as intended—maybe too well—turning an ordinary person into something far beyond human limits.
The tragic irony is that Oldface was killed by his own creation. Beefcake, now a towering mutant with a distorted sense of reality, mistook him for Saitama during a confrontation and struck him down without hesitation. It's one of those dark moments that defines what happens when scientific ambition goes unchecked and family bonds get caught in the crossfire.
