Toxxin was the high priest of a small village outside Atlantis They had developed a symbiotic relationship with a tentacled monster named Krakor who lured in and ate all of the predators that would attack the village. Toxxin believed that it would turn on them though, and there was a prophecy that a champion would die while killing it to save his maiden. Aquaman and Mera were kidnapped to complete the prophecy, and forced to slay the Krakor thus exposing the village to attacks by more violent marine predators. Toxxin attempted to murder Aquaman so that in his mind the prophecy would be completed as foretold, although Aquaman simply knocked him out and left before having to confront any further dangers.
