Cover by Herb Trimpe and Bob McLeod. At Gamma Base in the Desert Southwest, Doc Samson continues his work to find a way to cure the Hulk. And during a break in his research, he receives a phone call from a fellow psychiatrist named Dr. Karla Sofen. She would like to come to Gamma Base and assist with treating the Hulk. Oh, how nice! Doc Samson welcomes her with open arms, but he's not aware of her true intentions. Dr. Sofen is actually there to steal components of the Gammavator for the criminal enterprise known as the Corporation. Once Karla completes her evening heist, she thinks she's home free! But on her way out of the storage vault, she runs into the Green Goliath! And then and there, the new Moonstone faces off with her first superhero -- none other than the Incredible Hulk!
