Their infighting had even jeopardized Oa and the Guardians during a Qwardian invasion. Guy Gardner had returned to Oa to take the yellow power ring of Sinestro. Without Kilowog to guide them, the Green Lanterns were in chaos. Kreon and Boodikka came to blows when the rival Green Lantern criticized her for being an undisciplined fighter. Running out of options, Kilowog brought the two squabbling Green Lanterns to John Stewart as a "guest lecturer" in cooperation and tolerance.

Fully charged, Gardner's yellow power ring enabled him to recognize the true threat. Created in the anti-matter universe of Qward, his power ring negated the mental block of the real attackers. Gardner used his ring to free the others from their trance. Boodikka's respite would not last long. An alien race called the Ophidians had come to cleanse known space. On two occasions in their sordid past they had been nearly annihilated by alien invaders – then since confining themselves
