Dilustel Armor: Captain Atom's metallic shell, or "skin," is composed of a portion of the alien being known as Silver Shield, and is called Dilustel. Pieces of the alien's metal body were used in the Captain Atom Project, Project Major Force and similar projects thereafter. Nathaniel is able to coat himself with the metal, either partially or totally. Atom's symbiosis with the metal is such that even partially armored, he is able to access the Quantum Field.
