Devil Dinosaur

Devil Dinosaur is a red dinosaur similar to a Tyranosaurus Rex that was born on an alternate Earth. He has somewhat of a telepathic link to a Neanderthal named Moon-Boy, his closest friend. For a dinosaur, Devil Dinosaur is highly intelligent and seems to understand most situations.

History
After being knocked off their jump jet, A-Bomb and Red Hulk encounter Devil Dinosaur under the control of Sauron who orders it to attack. Upon being alerted of She-Hulk and Skaar attacking his drill at the super-volcano, Sauron controls Devil Dinosaur into finishing the attack. Devil Dinosaur ends up swallowing A-Bomb as he then charges towards Hulk. Hulk and Red Hulk then fight Devil Dinosaur to get A-Bomb out of him. Upon being freed from Sauron's mind-control, Devil Dinosaur regurgitated A-Bomb as Devil Dinosaur becomes friends with A-Bomb. Devil Dinosaur helps to fight Sauron's forces and destroy the drill. Devil Dinosaur is brought back with the Agents of S.M.A.S.H. as their "pet."

Powers
A mutant dinosaur with human-level (or above) intelligence, and superhuman strength.
