Shark debuted in Green Lantern #24 (October 1963). He is a tiger shark that rapidly mutated after exposure to nuclear waste. The rapid evolutionary growth ENEMY GREEN LANTERN AND AQUAMAN gives him high intelligence, a humanoid appearance, and telepathic powers, but leaves him with his bloodthirsty shark instincts.

Shark's killer instincts drive him to seek out prey that he can terrify. He eventually seeks out Green Lantern when he learns that the hero is without fear. Even though he uses his telepathy to discover Green Lantern's vulnerability to yellow, the Shark is unable to overcome the Green Lantern's will power. Green Lantern uses his ring to devolve the Shark back into his primitive form, then places him under guard at the Coast City aquarium.

Shark manages to return to his evolved state many times, and returns to fight the Green Lantern, as well as Superman and Black Condor. At one point the Shark is able to evolve into a human form; now using the name "Karshon" he manages to temporarily depose Aquaman as the ruler of Atlantis. Aquaman is able to expose Karshon and forces the Shark to devolve.

During the Crisis on Infinite Earths, the Shark joins Guy Gardner's fight against the weaponers of Qward.

Post-Crisis, the Shark returns in Green Lantern vol. 4 #5 to face Hal Jordan again. In his latest appearance, his form is more monstrous, with webbed fingers, claws, and a large fin on his back. His new appearance is caused by experiments performed on him by aliens known as the Gremlins.

Infinite Crisis[]

A further mutated Shark appears in Infinite Crisis, as part of the Secret Society of Supervillains's attack on Atlantis. Along with King Shark, he kills Neptune Perkins. The Spectre soon devastates the entire area, seemingly killing everyone in the city and around it.
