Hal Jordan's enemies: Parallax (The Final Night and The Spectre)
When Hal Jordan sacrificed himself rekindling the sun, he became the Spectre, the Spirit of Vengeance. Still, Parallax remained bound to him. The Spectre explained to Jordan the truth about Parallax. At the same time, at the headquarters of the JLA, Kyle Rayner shared similar information with Green Arrow. Rayner explained that he journeyed to the edge of the universe, and on the tenth planet from the star Pagallus, the inhabitants told him that Parallax was actually a yellow demonic parasitic entity that was born at the beginning of sentience, feeding on fear, creating terror in anything it came into contact with, and causing entire civilizations to destroy themselves out of paranoia.
