Karl
A former member of the Golden Cheesecake Pirate Armada. He was described as the "angry black man trying to get out the hood". He initially appeared in several Golden Cheesecake Pirate Armada Sidequests starting with The Newport/Hoboken Adventures. The story of how he met and joined the crew was shown in The Golden Cheesecake Pirate Armada Sequel. However, he was afraid to join the GCPA because the hood was constantly hunting him down and Karl feared they would target the GCPA to get to him. However, that intended running gag never re-emerged. Did he even have any powers?
Well in the two sidequests taking place in Newport and Hoboken he had his largest role when he entered a Johnny Rocket's and began working there, causing him to develop the superhero alterego known as Johnny Rocket. He attacked simply by offering food to the criminals he encountered. This would cause their arteries to explode decades later; Justice is patience.
Karl, whose real life counterpart seemed pretty indifferent to the GCPA anyways, was later among the many souls that the GCPA sold to Chevy Chase in order to get their new ship in Welcome to the Summer Youth Program Bitches!.
