Tales to Astonish, Vol. 1

Alex Gentry is tired of creating military weapons with little or no compensation. He designs a combat suit inspired by the porcupine, and uses it to easily rob an "unrobbable" bank, depending on security measures Henry Pym designed. (This is probably why Dr. Pym is a famous biochemist, and not a famous engineer.) Ant-Man and the Wasp track Porcupine to his hideout and stop his current crime spree, but are unable to capture him.
