"Castaway!"
Sentenced to death by the people of Atlantis, Aquaman finds that Atlantis' sorcerers have turned the creatures of the deep against him. He finds his way to some sort of haven, where he is met by the Lady of the Lake, who longs to let the world know of her waters of truth. She chooses him as her champion, and fashions a new hand for him from life-giving waters. Later he is discovered by his old friend the Martian Manhunter.
