Stephen Weems was a scientist whose experiments into molecular dissolution caused his own molecular structure to begin breaking down. He was forced to build a metal exo-skeleton in order to stop himself drifting apart completely, and joined the criminal group called the Conspiracy believing they could help him but they were defeated by Ulysses Bloodstone. Later, partnered with Killer Shrike, he seemingly attempted to stabilize his condition again but proved to be simply attempting to become a being of pure energy and incredible power, causing him to come into conflict with Spider-Man and the Beast, who were forced to cause him to dissipate. All that remained of Weems was a burned out metal shell.
Modular exo-skeleton of his own design which stopped his molecules from drifting apart.
