Action Comics #519 Comic Book

Aquaman backup story.

Superman tries to prevent an alien hunter from destroying a monster which he soon learns destroyed the alien’s planet. Cal Durham learn the strange history of Aquamans mother: that Atlanna was a survivor of the original Atlantis, thanks to her taking a serum of her own invention that made her amphibious and nearly immortal; that her sister, Atlena, was a priestess of the Delphius Oracle, which proclaimed that a savior would be born to become king of sea and land people; that Atlanna did not really die in Aquamans childhood, but was merely rendered comatose.
