Nuclear radiation led to the mutation of a humanoid monster known as "The Shark". The Shark has increased intelligence and psionic powers as a result of this mutation, but retained his species' primal predatory cravings. He can survive on the psyches of enemies as well as their flesh. The Shark continues his sinister mutations evolving into a more vicious creature with every transformation. He recently joined the reconstituted Secret Society of Supervillains for an attack on Atlantis.
