Devil Dinosaur #4

A huge spaceship lands in the Valley of Flame. The occupants are large gold and blue humanoid robots with flamethrower arms. They begin to ransack the Valley, killing and capturing Dinosaurs and cavemen alike including Moon Boy. Meanwhile Stone-Hand and White-Hair, two members of the Hill-Folk (gray furred cavemen), see Devil Dinosaur attacking one of the robots that was battling a \"Thunder-Horn\" (Triceratops). Stone-Hand helps Devil Dinosaur destroy the robot winning his trust and becoming allies with him. The threesome then plan on how to defeat the aliens.
