What if... Staring Captain America's shield
I was re-reading Road of the Patriarch and after reading the part where Artemis release all the mechanical energy he absorbed into some unsuspecting orc (causing him to virtually explode) I started wondering about a similar situation involving Cap's shield.
What if Captain America's shield had a limit to amount of energy in could absorb (like Vibranium) and having suddenly reached it's limited exploded with out warning, releasing all the energy it had absorb over the years in one awesome burst. How much damage would it cause? Would it destroy the Earth? Would it knock Thor on his ass if he was anywhere near? You tell me.
