Prince Namor... The overrated Sub-Mariner... Is all washed up as a power beneath the sea! And I'm the one who finished him! Me... Tiger Shark!! Now I'm ready to take on all comers for the throne of Atlantis! To the victor will go the crown... And to the vanquished... DEATH!
~ Upon singlehandedly taking over Atlantis


Tiger Shark was once Todd Arliss, a champion Olympic swimmer who took part in the Olympic Games. He later damaged his spinal cord when he rescued a drowning man who had fallen overboard from a private craft. Desperate to regain his swimming ability, Arliss willingly participated in an experiment by the scientist Dr. Lemuel Dorcas, who "cured" him by blending his DNA with that of Namor the Sub-Mariner and a tiger shark.

Although successful, the process changed Arliss both physically and mentally: he now had razor-sharp teeth and gills and had become savage and predatory, becoming one of Namor's greatest and most dangerous enemies.

This mutation has become a curse more than a blessing however, as his mind and appearance twist back and forth between a more humanoid look and a more monstrous look. Likewise, he has often aided his nemesis, the Sub-Mariner, and saved innocent lives, as a gesture of goodwill, and other times threatened them for no good reason. The man that was once Todd Arliss still lives, somewhere within...
