Mister Mind directs a number of his agents (many of them civilians) to position themselves near nuclear facilities, with a view to capturing them for his own ends. Meanwhile, Mind himself, using a marine as a host, moves to a vault below the White House, containing an alien power suit recovered by Minute Man and Bullet Man in issue #36. In the suit, Mind has the physical power to take on Captain Marvel and Mary, head to head. The power suit also transforms Mind into a giant worm, while he explains that he plans to engineer a nuclear disaster to wipe mankind from the earth.

Meanwhile, heroes around the country attempt to prevent hosts possessed by Mister Mind from triggering nuclear catastrophes. Meanwhile, the battle continues and Captain Marvel realises that Mister Mind's giant form is an illusion and he is, in fact, still in his power suit. Hal Jordan and Kyle Rayner (current day Green Lanterns, albeit Hal only sort of) arrive on the scene and attack Captain Marvel, having been tricked into thinking he was Mister Mind. When they realise their mistake, the lanterns and the Marvels work together to tear apart the power suit and capture Mister Mind. Finally, Sargeant Steel arrives with the same kind of weapon that Mary used in issue #40 to kill Mister Mind, removing the last lingering threat of nuclear attack by his agents.

With that in mind, Tawny decided that they must still travel through time for help. In the hospital, Mary and Freddy are recovering but Billy's condition looks grim. While the Bromfields consult a doctor from Star Lab regarding Chain Lightning's relationship with Freddy, Lightning's id and the little girl break into the hospital to kidnap Freddy. Freddy convinces the little girl that she no longer knows what Chain Lightning wants, since they are no longer an integrated personality. This buys Freddy a little time while the girl and the id seek out the other portions of Chain Lightning's personality. Meanwhile, in the time stream, Tawny has recovered Thunder from the far future to try and help the current day Marvels. Unfortunately, their travels are interrupted by Black Adam, who casts Thunder adrift in the time stream and uses Tawny to get back to our era, purportedly at the request of Ibis.
