While Sauron controls Devil Dinosaur into attacking A-Bomb and Red Hulk, She-Hulk and Skaar find Sauron's lizardmen allies using a special drill in the super volcano. Sauron is alerted about the situation at the super volcano and commands Devil Dinosaur into finishing the job. pon 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. Sauron engages Skaar in battle as he tries to mind control him, and drains the energies of him and She-Hulk.
