Aquaman in "Toxxin's Raiders"
Aquaman and Mera are captured by the high-priest Toxxin. Toxxin informs them that his village is surrounded by a plant-creature by the name of Krakor. He tells them about a prophecy that claims that a mermaid and a champion would destroy the Krakor, and that is the reason they were brought there. Aquaman and Mera then defeat the creature and are free to go home.
