Ryker's Island
Bill Norris, the first Mr. Fish's similarly-mutated brother, was introduced visiting an exotic nightclub with the Walrus. He subsequently joined the Flashmob, a group of former opponents of Luke Cage, during "Shadowland". The assemblage of villains confront the new Power Man, and are remanded to Ryker's Island after being defeated by him and Iron Fist. A few members of the Flashmob, including Mr. Fish, are eventually bailed out by Big Ben Donovan.
