Green Lantern: Rebirth was a six-issue monthly American comic book limited series written by Geoff Johns and illustrated by Ethan Van Sciver. Published by DC Comics between October 2004 and May 2005, the series featured characters from throughout the sixty-year history of Green Lantern comics. The storyline follows the "rebirth" of the Silver Age Green Lantern Hal Jordan as he overcomes fear itself in the form of the cosmic entity Parallax. The series starred various members of the intergalactic police force known as the Green Lantern Corps, Kyle Rayner, John Stewart and Guy Gardner. It revived elements of the Green Lantern mythos including the Guardians of the Universe, Kilowog and the villain Sinestro, while introducing new concepts such as the emotional spectrum. In addition, the GLC power ring's flaw of being unable to directly affect the color yellow is significantly weakened, allowing experienced Corps members to overcome it if they can conquer their fear. Background In 1994, DC Comics decided to do away with Hal Jordan, who had been the primary Green Lantern of Earth since his first DC Comics appearance in 1959, and replace him with a new character to carry on the Green Lantern legacy, Kyle Rayner. The storyline, Emerald Twilight, which began in Green Lantern (vol. 3) #48 (January 1994), involved Hal Jordan descending into madness following the complete destruction of his home town, Coast City, by the villain the Cyborg Superman. This caused Jordan to become the villain Parallax. Jordan went on a rampage on the planet Oa, the planetary citadel of the Guardians of the Universe, who oversee and administer the Green Lantern Corps. He killed some fellow Green Lanterns who opposed him and all the Guardians save for one, Ganthet. He also destroyed the Central Power Battery, with which all Green Lanterns recharge their power rings, and even killed the renegade former GL, Sinestro, whom Jordan himself had exposed as a criminal who used his power ring to enslave his planet and whom the Guardians apparently freed from his imprisonment in their Central Power Battery in a failed attempt to stop Jordan. Jordan then attempted to destroy all of existence so that he could recreate it to his liking in the 1994 miniseries and crossover storyline, Zero Hour. "Emerald Twilight", as scripted by Ron Marz, provoked severe outrage amongst many Green Lantern fans. While retaining Kyle Rayner as the sole remaining Green Lantern, DC
