While on a visit in northern Italy under his secret identity, Earth-One's Flash witnessed the strange appearance of a stunning alien. Fire-Lord was brazenly transforming various people into duplicates of itself, with the intent of exercising his control over all around him. This was so that he could claim rulership on planet Appellax!
Another fiery madman desiring control of the Earth-Two, was Mazda the Great who wore an asbestos suit as had his minions while operating an experimental steam machine. When Hawkman was tipped off to the villain's goal of world domination, the Winged Warrior alongside girlfriend Sheila Sanders faced him.
Both Fire-Lord and Mazda the Great found their flames snuffed out by the pair of planetary protectors. Yet how would a combined Justice League of America handle the Wood-King, and how would his threat be mirrored by mad scientist Doctor Faversham?
