- Crash, lightning! Roar, thunder! You can't hurt me!
- -- Master Man src
When Master Man was a weak, scrawny boy, a wise old doctor gave him a magic capsule, full of vitamins, containing every source of energy known to man: the Vitacap. He grew up to become the strongest man on Earth, and built himself a stone castle atop the highest mountain, and from there he sees all evil in the world, and races to destroy it instantly.
- This version of Master Man, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
