When the entity known as Parallax corrupted fellow Green Lantern Hal Jordan, the Guardians dispatched Ke'Haan and Laira to stop him from reaching Oa. The pair found themselves outmatched as Jordan, powered by rage and psychosis, tore through them. Surprisingly, despite his imposing figure, years of experience, and overwhelming strength, Ke'Haan was the first to fall to Jordan, while his pupil Laira, while still losing, fared much better in her attempts at stopping Jordan.[2]
