Emerald Twilight

In Green Lantern #46, as part of the "Reign of the Supermen!" storyline, the extraterrestrial villain Mongul teams up with a Cyborg Superman that had been passing himself off as the real Superman. They use a series of bombs to destroy Hal Jordan's home city of Coast City with the intention of using the area as one of four way-stations for a giant engine that would ultimately transform Earth into the massive spaceship Warworld. Hal Jordan returns to the city to find a massive fortress-engine standing in the ruins of his home and furiously attacks, hearing the voices of those killed crying out in his mind. The voices fall silent when Jordan defeats Mongul in battle. Hal also witnesses the return of Superman, who has defeated the Cyborg elsewhere in the city.

In issue #47, he teamed up with Green Arrow for a completely different mission, and at the end of the issue, his thoughts once again turn to Coast City.

Issue #48 began with Hal in the center of what used to be Coast City, clutching the remains of a doll—the only physical evidence of the seven million people who once lived there. 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 is in violation of one of the principal rules of the Green Lantern Corps, which forbids Lanterns from using their rings for personal gain. Enraged at their apathy, Hal siphons off the energy from the projection and makes his way to the Guardians' planet Oa, with the intent of bleeding off all the energy from the Main Power Battery in order to permanently re-create Coast City.

Issue #49 saw him going up against various members of the Green Lantern Corps, each of whom fell against Hal, until he got to Oa. Hal steals the rings from each defeated colleague and leaves them for dead.

Issue #50 sees Hal battle the renegade former Green Lantern Sinestro on Oa, who had been previously imprisoned in the Main Battery, but released by the Guardians to stop Jordan. Jordan then proceeds to kill Sinestro, as well as his fellow Green Lantern Kilowog. The Guardians, having realized that their cause was lost, had given all their remaining energy to the Guardian named Ganthet, who became the sole Guardian after this energy transference resulted in the death of the rest of them. Hal takes all the energy in the Central Power Battery, and when he emerged from it, he has a new costume and takes the name Parallax.[1]

Ganthet travels to Earth and finds an illustrator named Kyle Rayner (who had been briefly introduced at the end of issue #48 when he saw Hal fly off and mistook his green flight streak for a shooting star). Ganthet gives Kyle the last remaining power ring, thus making Kyle the last Green Lantern.[1] As Parallax, Hal Jordan became a recurring villain in the DC Universe.

In "Emerald Fallout", which takes place in issues #18–21 of Guy Gardner: Warrior, Guy Gardner receives a vision of the events of "Emerald Twilight". Guy, along with Wonder Woman, Alan Scott, Arisia, Darkstar Ferrin Colos, the Martian Manhunter, Captain Atom and the Ray go to what was left of Oa. He challenges Hal and is defeated when Hal melts his yellow power ring.

The character played a central role during the Zero Hour storyline. Later Hal displays his final act of heroism, sacrificing his life to reignite the Sun at the conclusion of The Final Night storyline. Redeemed in the eyes of many of his fellow heroes, he received a hero's funeral. Not fit either for Heaven or Hell, Jordan's soul was destined for Purgatory, until he became the newest host for the spirit of God's vengeance known as the Spectre, at the end of the Day of Judgment limited series.[1]

During the events of Green Lantern: Rebirth, Hal Jordan's murderous actions were revealed to be the result of being under the influence of the fear entity Parallax. Parallax chose Hal at the behest of Sinestro (who was puppeteering a hard-light duplicate of himself in the battery during their battle on Oa). Jordan is eventually resurrected and returns as a Green Lantern once more, as well as resuming his career as a Captain within the United States Air Force. His and the Guardians' return signify the rebirth of the Green Lantern Corps.

Originally "Emerald Twilight" was scripted by Gerard Jones and according to Previews Vol. III #8 (Aug 1993) and the November 1993 Comics Scoreboard, was to involve two sets of the extraterrestrial altruists known as the Guardians and Hal Jordan, a member of their intergalactic police force, the Green Lanterns, having to choose which set was real. DC Editorial did not think this idea was interesting enough to draw new readers so then-publisher Paul Levitz, along with senior group editors Mike Carlin, Dennis O'Neil, and Archie Goodwin, and Green Lantern editor Kevin Dooley plotted the "Emerald Twilight" story. It was given to Ron Marz to write.[2]

• "Emerald Twilight" was to be adapted into a video game for the Super NES by developer Ocean Software. The game would have allowed players to assume the role of Kyle Rayner and take on Hal Jordan. The game was cancelled.[3]
