“In brightest day, in blackest night, no evil shall escape my sight. Let those who worship evil’s might beware my power…Green Lantern’s light!”

Those are the words of the ancient oath that every member of the Green Lantern Corps, the most elite institution the universe has ever known, must speak aloud before doing their sacred duty and charging up their emerald power rings—the most powerful weapons in the universe. The members of this intergalactic police force come from every known sentient species in the cosmos, each a fearless warrior with indomitable willpower.
