Battle Of The Power Rings! After Green Lantern's power ring fails on him fighting crimes on Earth, Hal figures there is something wrong with the charge and returns to the Ferris Aircraft Company to recharge his ring. He falls right into a trap laid out by Sinestro, who has a power ring of his own and uses it to freeze Hal in place. Sinestro explains that he made the ring -- which siphons power off power ring energy, before Green Lantern imprisoned him during their last battle and used it to escape the prison he was placed into. Trapping Hal in a energy cage, Sinestro then uses his ring to change his appearance to look like Green Lantern, as part of a plot to destroy the Guardians of the Universe.
Infiltrating a meeting of Green Lanterns from various sectors of space, the fake "Hal Jordan" creates a menace for them to destroy with their power rings, little knowing that their "ally" is siphoning the energy from their power rings that he needs to attack the guardians. With his mission a success Sinestro leaves, dropping his disguise, to attack the Guardians on Oa.
