Item Biography
Aquaman in "Crown, Crisis and Cataclysm"
Captured by Black Manta, Aquaman is brought to Atlantis to face Karshon. He then discovers that it was Karshon who framed him and stole Serum X. Karshon then transforms into his real identity, that of the one of the Green Lantern greatest enemies, the Shark. The Shark informs Aquaman that he has his family held captive. The Shark tells Aquaman that he is going to hunt him, and if he escapes alive he'll free his family. During the hunt Aquaman is wounded but manages to lure the Shark to a nuclear waste dump, where the radiation reverses the Sharks mutation, which turns him back to a real shark.
