Marvel Monsters: Devil Dinosaur #1

Two Celestials, Gamiel and Devron, witnessing Earth's evolution observe that a small, peaceful species, with the help of a dinosaur, is dominating a larger, more combative species; however, this disrupts Gamiel's theory that the strong will survive. To offset the dominance of the dinosaur, Gamiel summons the Hulk from the future to fight the dinosaur. Devron counteracts Gamiel's interference which results in unwanted consequences.
