Argent was sort-of the Captain America of my old Proteus campaign. She was a cop in Puerto Rico who was blown up and horribly injured; Doctor Vanderen rebuilt her, giving her advanced bionics and artificial skin that was possessed of incredible defensive properties. When these properties were active, it turned metallic silver, hence her alias.
