“The Doom Trip!”
The Thing knocks Godzilla out of the huge shark tank and Mr. Fantastic then smothers him with his pliable body rendering him unconscious. It's decided that the best thing to do is use Dr. Doom's time machine to send Godzilla back into the prehistoric past to be with his kind. The deed is done and Godzilla awakens in the Valley of Flame (domain of Devil Dinosaur and Moon Boy). Devil Dinosaur attacks Godzilla and a fierce battle ensues until Moon Boy discovers that the valley is being invaded by the Lizard-Warriors; cavemen wearing dinosaur hides for clothes and riding on dinosaurs as mounts.
