King Shark is a DC Comics supervillain. The character was introduced in Superboy (vol. 4) #0 (October 1994).
Born in Hawaii, Nanaue is a humanoid shark. His father is "The King of all Sharks"—also known as the Shark God. Other characters, such as special agent Sam Makoa, have dismissed this as superstition and referred to Nanaue as a "savage mutation" with no mystical nature. Given the reality of magic within the DC Universe, either origin is equally possible. It has also been implied he was one of the "Wild Men", evolved animals based on those in Kamandi: The Last Boy on Earth. The now-ended Aquaman: Sword of Atlantis series, however, seems to have put an end to the controversy by firmly establishing him as the Shark God's son.
King Shark was responsible for several missing persons several years before Superboy arrived in Hawaii. Sam Makoa was responsible for bringing him in and bore the scars forever after. King Shark is freed by the Silicon Dragons who plan on hiring him. Nanaue is not interested, however, and kills his liberators before heading to his mother's house. His mother allows him to bite her arm off to feed. Superboy managed to take him down by firing a point blank blast of heat vision from his "X-Ray specs." When Superboy and Makoa were assigned to the Suicide Squad to destroy the Silicon Dragons, King Shark was forced to help. An explosive belt was strapped to his waist, set to detonate if anything happened to Makoa. Other members of the Squad included Knockout and Squad veterans Deadshot and Captain Boomerang.
Nanuae was a crazed fighting machine, shredding legions of the Dragons (and killing Sidearm too, when he betrays the team). Despite the belt detonating, King Shark survived the blast and the destruction of the lair.
