Crabmeat was an ordinary crab before being altered by Dr Piranoid. But before he could get to work on his mind, the crab went on a rampage and busted out. After regaining his composure, the crab began to wander Fission City and began to target criminals and stop them, catching the eye of the Street Sharks. Upon meeting them, he assumed they were Seaviates and began to attack. After the Sharks explained that they were also enemies of Piranoid, Crabmeat decided to join them as their ally. A rough-around-the-edges character, he is always itching for a fight, but nonetheless is a good guy.
