Who? One of the first and most inventive supervillains of the Marvel U, Alexander Gentry started out as a weapons designer for the U.S. military, creating a suit modelled after the porcupine that used quills for both defence and offence, along with the odd flamethrower, chemical spray and gas canisters for good measure. Gentry was a paranoid sort and, believing that he wouldn't be adequately rewarded for his marvelous creation, decided to take the suit for himself and become the nefarious but somewhat ineffectual villain The Porcupine. Upon attempting his first bank robbery he was quickly stopped by Ant-Man and Wasp, instilling a hunger for revenge in Gentry that was never quite sated. Why Stoll Could Play Him: To be fair, anyone could likely pull off this character in costume, but outside of the suit the character needs to be a paranoid mess of neuroses, and Stoll has the "hot mess" type down to a T from his time on House Of Cards. The Porcupine would again fit the ideal criteria for a comedy supervillain: borderline ludicrous in concept, but with more than enough emotional baggage to make him a solid character and genuine threat.
