After Coast City is destroyed by Mongul and the Cyborg Superman, Hal Jordan tries to recreate it. Even if it means destroying everything he believes in and killing his friends.
It begins with Hal in the center of what used to be Coast City, clutching the remains of a doll. In a moment of pure anguish, Hal uses his power ring to re-create Coast City, down to the people who had previously died, including his father. When his ring’s energy runs out, one of the Guardians of the Universe contacts him via a holographic projection to tell him he has violated the principle rules of the Green Lantern Corps, which forbids Lanterns from using their rings for personal gain. Enraged, Hal siphons off the energy from the projection and starts his journey to the planet Oa, with the intent of using energy from the Central Power Battery of Oa in order to permanently re-create Coast City.
The Guardians send fellow Green Lanterns to stop Hal Jordan. Jordan can’t be reasoned with and continues head on destroying and killing anybody that stand in his way. The first to fall, and certainly not the last, was Tomar-Tu. The most notorious casualties included Jack T. Chance, Boodikka, Kreon, Ke’Haan, Graf Toren, Honnu, and Laira.
When Jordan arrives on Oa, he is forced to battle the renegade Green Lantern Sinestro, who had been freed from the Central Power Battery by the Guardians. Jordan kills Sinestro, as well as his fellow Green Lantern Kilowog. With no one left to defend them, the Guardians, having realized that their cause was lost, gave all their remaining energy to the Guardian Ganthet (who became the sole Guardian). This energy transference resulted in the death of the Guardians. Hal takes all the energy in the Central Power Battery, and when he emerges from it, he has a new costume and takes the name Parallax.
