The final showdown between Namor and Doctor Hydro is here at last! Can the prince of the blood defend his realm from catastrophe? And the ancient legend of Atlantis continues!

This book also contains another story, the second "Tales of Atlantis." These stories relate the origins of sunken Atlantis, although this one is set in the Hyborian age between Kull and Conan, and deals with pre-Cataclysm Atlantis. It is scripted by Steve Gerber, co-plotted and penciled by Howard Chaykin, and inked by Joe Sinnott. King Kamuu and Queen Zartra are the characters in this story.
