Impervium

Impervium is a unique “living metal” created by ASTRO Labs. Not only incredibly hard and durable, Impervium also has a remarkable ability to “heal” damage over time. It also “remembers” its original shape enough to regenerate or replace damaged parts, making it incredibly useful in situations where wear and tear are concerns.
The process and materials to produce Impervium are expensive, making the metal far too costly for common use or public consumption. Still, some government facilities make use of Impervium armor and the Blackstone prison uses Impervium cells and restraints. ASTRO Labs also has a number of Impervium-related research projects underway. Security around the formula and materials is tight, particularly ever since the renegade robot Talos attempted to steal them.
