Cunning Chang's Crafty Conniving Cultivates Crystal's Control

Chang was a lampmaker in ancient China who witnesses the arrival of a green meteorite, possessing immeasurable power. Using his skill to craft a lamp from a portion of the alien rock, Chang believed this would enable him to harness its energies and bend them to his will. However, the meteorite was a remnant of energy originating from the Starheart, and extraterrestrial entity whose radiation was spawned from a parallel universe. That realm was under the supervision of the Guardians of that Universe, tasked will protecting that dimension from evil spawned from one of their own. While the energy they encased in a globe was incompatiable in their universe, it was functional in that of the universe that contained Earth-Two, where the meteorite landed.

Given his evil agenda, the energized entity behind the meteorite struck out at Chang and his servants, however their master survived thanks to the piece of rock that the lampmaker clunk to. Embittered that he was denied his dreams, Chang was still gifted with immortality, and thus founded an order of minions known as the Green Dragon Tong that would serve him. Naturally, he was opposed by fellow Chinese of a more noble disposition, who claimed the lantern and gave it to a time displaced Alan Scott in the middle ages, as well as other worthy possessors down through the centuries.

Chang knew that in order to control the lantern, he had to corrupt the power behind it. And so, Chang lured an unsuspecting dupe in Charles Halstead, aka Psycho-Pirate. Halstead sought liberation from a debilitating mask the uncased his emotion-enducing powers originating from his facial expressions. Thinking he had stolen a powerful green globe from the old man, secretly Chang, he had in fact used his powers as the Psycho-Pirate to turn the globe's energies to his will. This freed him from the mask, and was the impetus for his next actions.

And thus, Psycho-Pirate naturally gravitated to the current weilder of that same emerald energy in Green Lantern, mentally controlling a distraught Alan Scott who was himself embittered at the loss of his previous Gotham Broadcasting Company. For a brief period, Green Lantern as well as fellow Justice Society members Flash and Batman, fought their teammates before recovering their senses. Psycho-Pirate was soon defeated by his adversaries, although his corruption of Scott and his power ring led to Chang finally gaining control over his own emerald powerstone. Soon after, Chang battled for control of the lantern with Scott, and only due to his being oblivious as to the weakness of the meteorite radiation to wood was Chang defeated forevermore. Still, Chang was far craftier than his Earth-One counterpart and fellow immortal Shann-Chi.
