Godzilla #21

In "The Doom Trip!", the Thing and Mr. Fantastic team up to subdue Godzilla after he escapes the shark tank, then enlist Dr. Doom’s time machine to send him back to the prehistoric past. Awakened in the Valley of Flame, Godzilla finds himself in a world of primal danger—where Devil Dinosaur sees him as a rival and the Lizard-Warriors, savage cavemen riding dinosaurs, begin their invasion. Written by D. Moench and illustrated by Herb Trimpe with colors by Ben Sean and letters by I. Watanabe, this 1979 Marvel classic features a cover by Trimpe that captures the chaos of the moment.
