In Poseidonis, one of the domed cities of Atlantis, Queen Berra gave birth to her baby boy, Garth, who was born with purple eyes. The Atlanteans claimed Garth had been born genetically inferior and sentenced him to death on a seabed leagues away from Atlantis. It has been speculated that with the assistance of Aquaman's father, the Atlantean sorcerer Atlan, the young Garth not only survived but thrived, learning language and survival rituals to keep the young boy from going feral as he scavenged his way through the undersea. Garth developed an intense fear of schools of fish, however, which haunted him into his teens.
