Los 4 Fantásticos #51

Synopsis

The Mad Thinker once again wants to tackle the F.F., though The Puppet Master at first wants nothing to do with it. Under mind-control, Ben fights Johnny while in mid-flight. However, the shock of seeing Johnny falling to his death causes The Thing to change back to Ben Grimm, freeing him from control. He rescues Johnny, then gets help from Reed. A specially-designed helmet worn by Ben causes psychic feedback. Reed hopes The Puppet Master, knowing they have a defense against him, will never strike at them again.
