Fantastic Four Vol1 #326

Frightful Four appearance in "The Illusion"

Mr. Fantastic stops by Four Freedoms Plaza to see how the FF are progressing, and then he tries to help the Human Torch flame off. Meanwhile, the Wizard has assembled a new Frightful Four: Klaw, Titania, Hydroman and himself. The Frightful Four attack at the exact time Reed is experimenting on Johnny! A desperate battle rages as the Invisible Woman, Ms. Marvel, and the Thing fight to repel the invaders.
