The return of Diablo! The FF's alchemy-wielding nemesis is back for revenge, but he'll have to face the new and improved team to get it! But who is the last new member of the Four?

The Inhumans come to visit the Fantastic Four and Crystal. After they leave, Diablo and his Elementals attack. One of his Elementals transmutates Crystal into a solid gold statue. Diablo uses water to fight the Human Torch and wind to keep the Thing busy. Meanwhile, an Elemental composed of the Earth's dirt defeats Mr. Fantastic and an Elemental of fire burns the oxygen out of the Invisible Woman's force field so she cannot breathe. Unfortunately for Diablo, he does not see Sharon Ventura and she hits him twice and knocks him unconscious. Reed says that Sharon has saved them just in time and Ben tells Sharon that she is going to join his Fantastic Four.
