AQUAMAN, the King of the Sea! Without delay, the super hero and his underwater friends surge toward the disaster. Suddenly, out of a black plume of oil, an even greater darkness emerges. The evil Black Manta is siphoning oil into his submarine. The Sea King can't believe the villain could sink to such terrible depths! Before the gulf is destroyed, AQUAMAN must convince his enemy that a threat to the sea is a threat to them both.
