The Yellow Spot used his evil witchcraft to kill off or entrance the minds of American scientists. The Spot, who could travel as a bat, went into the home of Dr. Moore to kill him. While being stabbed, Moore somehow managed to throw the switch giving life to his Dynamic Man. The Yellow Spot's fiendish plan was put to a stop by Dynamic Man, who released the trapped minds of the other scientists. Dynamic Man then eliminated the Yellow Spot, who could only be killed in his bat form.
