Fantastic Four #96 (1969) First Print

THE MAD THINKER AND HIS ANDROIDS OF DEATH! Once again trying to gain control of the Baxter Building, the Mad Thinker has created android duplicates of the Fantastic Four who are sent out to attack and capture the other members of the group. While Ben is knocked out at the Baxter Building itself, Johnny and Sue are subdued and replaced by their android counterparts in public.   When Reed is attacked by the android version of himself, he manages to defeat it and pose as it, enabling Reed to get back into the Baxter building and free Ben. The two heroes then bust up the Thinker's androids and capture the Thinker himself. After turning the Thinker over to the police, Reed and Ben locate the sedated Sue and Johnny at the Thinker's hideout and revive them.
