A hard metallic alloy that was invented in the late 1980's by musical pop-star
Adam Ant.
It is often melted down and applied as a type of
hair mousse amongst image conscious musicians to produce a "big hair" look that is not only functional but is also completely resistant to moisture, heat, radiation, acid,
hurricane force winds and small arms fire.
Hey
Rogue,
how do you get your hair to do that?
I put
adamantium in it.
