By 1947 Degaton is assisting Professor Malachi Zee, a former member of the Time Trust who is developing a time machine. Degaton plans to take the machine for himself and shoots Zee. Several times Degaton tries without success to alter the course of history for his own benefit, including thwarting the course of historical events like the Battle of Arbela between Greece and Persia in 331 B.C., thus halting technological development and allowing him and his henchmen to conquer an America of ancient technologies with modern weapons which he had left in specially-prepared caves, safe from the alterations to the time stream. The JSA stop various plans by Degaton and history reverts to normal, with everyone losing the memory of these events, due to time paradoxes inherent in Zee's time machine. The story closes with Professor Zee in his lab with Per Degaton, who seems to remember some foolishness about him dreaming that he ruled the world. The JSA is able to learn of their own success through Wonder Woman's magic sphere.
