Lagoon boy was created by Erik Larsen and Eric Battle. Lagoon Boy first appeared in Aquaman #50(1998).

Lagoon Boy attended the marriage of King Orin and Queen Mera. There, Lagoon Boy befriended Sheeva, a beautiful mermaid, and Blubber,a whale with a genius IQ. In Aquaman #54,they called themselves "The Landlubbers". They built a TV and a computer that could work underwater. "The Landlubbers" were so curious about the surface that they went up to it. Their appearances frightened the civilians. Aquaman later rescued them and brought the three back to Atlantis.

Lagoon Boy helped Robin, Superboy and Impulse defeat Kobra Prime during the No Man's Land period. Later on, Lagoon Boy joined Young Justice as a reserve member,as did Changeling, Flamebird, Captain Marvel Jr. and Batgirl. Their only battle was with Klarion and Lil' Lobo. Lagoon Boy was seen helping out in Young Justice:Sins of Youth in which he was aged to adulthood and Aquaman became a kid. They faced off against Klarion the witch boy and Black Manta, helping the JSA, JLA, the Titans and Young Justice. In Young Justice #50, Lagoon Boy was shown controlling humpback whales, aiding Young Justice in the capture of the evil dictator of the nation called Zandia.

Lagoon Boy discovered a conch shell that could call out his pet Spotty, a monstrous sea creature from the Devil's Deep. Unfortunately it called out another vicious creature, which wreaked havoc upon the harbor of Gotham. Lagoon Boy teamed up with Robin to tame it and bring it back to the oceans in Robin #83-84.

Lagoon Boy was also shown in Infinite Crisis #4 in which the Spectre was attacking Atlantis. Lagoon Boy appeared battling it along with his fellow colleagues.

Lagoon Boy later returns for the Titans East Special#1.
