Atoman NPC For a Survive This!! Vigilante City campaign set in a Public Domain Super Heroes (PDSH) version of New York City

 Atoman is a formidable, high-powered NPC for Survive This!! Vigilante City RPG, classified as a "MegaHuman" with substantial energy-based powers, reflecting his origin as a being of raw atomic energy.

While working as a nuclear scientist at the "Atomic Institute," Barry Dale absorbs the "power of the atom" through unconscious exposure to nuclear materials and gains superpowers as a result. As described by Barry himself: "Evidently my body is so geared as a result of working on radium and uranium that it can explode atoms and give me atomic strength." He uses his new abilities -- such as super strength, flight, speed, invulnerability, "atomic vision," and the ability to heat his body so that he can weld metal with his hands -- to fight crime.
