Tales of Suspense #13

A scientist creates a computer so sophisticated that it can out think human beings. It hypnotizes the scientist into building it a huge robot body so that it can move and threaten human cities to conquer them. As it gets further from the scientist, the hypnosis fades, and the scientist regains his own will. He rushes Elektro, and enters the robot frame from a small door in its heel, and removes the power source, thus saving humanity.
