(Green Lantern: Rebirth #3 (fb)) - Parallax was awakened inside the Central Power Battery by Sinestro and infected himself on the soul of Hal Jordan.

(Green Lantern III #48-50 (BTS), Green Lantern: Rebirth #3 (fb)) - The destruction of Coast City allowed Parallax to further his control over Hal. After the Guardians forbid him from rebuilding the city they placed a number of Lanterns in his way as he made his way to Oa and he maimed or seemingly killed all of them, including Kreon, Tomar-Tu and Kilowog. He claimed each defeated Lantern's ring as his own, and his brutality increased with each encounter. He reached Oa and prepared to drain the central power battery when the Guardians released Sinestro from the battery to battle him. Hal defeated him and broke his neck. Hal blamed the Guardians for his actions because they refused to restore Coast City, but told them he was so far gone he couldn't stop now. He absorbed the power battery, freeing Parallax and allowing him free reign over Hal. Hal / Parallax killed the Guardians, though he was unaware that Ganthet survived the attack.

Hal took on the identity of Parallax. With Extant at his side he tried to remake all of space-time, but was foiled by Earth's heroes.

(Green Lantern III #105, 106 (BTS)) (During Zero Hour #4) - Parallax sensed a disturbance in the timestream. He knew his past self from 10 years ago was stuck in the near future, so Parallax went into the future to return himself to his own time. He wrecked Warriors and battled Guy Gardner and John Stewart to learn the location of his past self, and flew off to the JLA Watchtower to retrieve him. He was confronted by Green Lantern Kyle Rayner and his past self, and he took them back in time to the moment before Coast City's destruction and tried to convince his past self that his quest to remake the universe was just. The younger Hal told Parallax he was destroying everything he'd worked for as a hero and they fought. Kyle Rayner told them that they both had to return to their own times, because Hal had to become Parallax so Parallax could soon give up his life to reignite Earth's son. Parallax was disturbed with the news of his inevitable fate, but agreed. Parallax and Hal used their power rings in conjunction with Kyle's to erase their memories of this time jaunt and return themselves to their own times.

(Green Lantern III #0 (BTS)) - When the universe was recreated Waverider created a rift to reenter reality and Parallax tagged along and brought Kyle with him. Parralax then brought Kyle to Oa and tried to absorb the green energy of the planet itself. Kyle and Parallax fought, but Parallax moved Kyle with his plea that he could make everything in the universe right again by recreating it. Kyle handed over his ring to Parallax but immediately regretted it and after a brief fight took it back. Parallax created a power ring duplicate of Kyle's dead girlfriend Alex DeWitt and promised to restore her to life when he remade the universe, but Kyle stood firm. He knew the only way to deal with Parallax was to cut off the source of his power, so he overloaded Oa with emerald energy until it exploded.

(Green Lantern III #63, 64 (BTS)) - Parallax came to Kyle Rayner's apartment and asked for his power ring back, telling him no one could replace him as Green Lantern and that it was time his life got back to normal. Kyle refused, and after a long fight Parallax defeated Kyle. Just as he reclaimed the ring Ganthet appeared with former JLAers Aquaman, Flash III, Green Arrow, Hawkman and Martian Manhunter. Parrallax defeated the heroes and when Ganthet summoned Superman Parallax bested him too. Kyle finally talked Parallax down, and Parallax realized he could never go back to being Green Lantern and he gave up the ring. Ganthet then merged with Parallax and they flew off.

(Final Night #4 (BTS)) - Hal / Parallax appeared to Earth's heroes and told them he was ready to save the Earth from the Sun-Eater. He needed to redeem himself, so he sacrificed his life to absorb the Sun-Eater and reignite Earth's sun.

(Day of Judgment #5 (BTS)) - The Spectre-Force merged with Parallax and Hal Jordan’s soul. The Spectre chose Hal as the new spirit of vengeance but also wanted to keep Parallax under wraps.

(Green Lantern: Rebirth #0, Green Lantern Secret Files and Origins 2005) - Hal argued with the Spectre-Force, who wanted him to forget his mission of redemption, and start exacting vengeance by killing killers. Hal refused, and the Spectre-force manifested Parallax as a separate entity, who briefly fought Hal before re-merging with him. The Spectre-Force told Hal that he, Hal and Parallax were all combined not only for Hal's own good, but also for the safety of the universe.

(Green Lantern: Rebirth #1 (BTS), 2 (BTS), 3-6) - Parallax sent Hal to the reconstructed Coast City where he appeared as a separate identity, told him he’db uilt up the city without Hal being aware of it and offered him the chance to completely rebuild the city and have Carol Ferris back as his own. The Spectre fought Parallax and revealed it hoped to burn Parallax from Hal’s soul but had failed. Parallax overcame both Hal and the Spectre, asserting dominance over both of them. Parallax took over the wills of Kilowog, Guy Gardner and John Stewart using their power rings and had them attack Guardian Ganthet, but Ganthet freed them from Parallax. Ganthet assembled some of Earth’s greatest heroes to combat Parallax, weakening him enough for Hal to fight his control. The Spectre separated Parallax from Hal’s soul, but it was divine will that he then chose to separate himself from Hal and abandon their conflict. Hal’s soul was called to the afterlife, but he knew he still had work to do, and his soul returned to his body, which Kyle Rayner had retrieved from the heart of the sun. Parallax took over Ganthet’s body, and prepared to spread fear throughout the universe. Hal and the other Green Lanterns combined their forces to drive Parallax from Ganthet’s body and trap Parallax in the Central Power Battery.

(Green Lantern: Sinestro Corps Special #1) - Sinestro and the Sinestro Corps brought Kyle Rayner to Qward and extracted Ion from him. After imprisoning Ion they infected Kyle with Parallax. Parallax enjoyed his new body and was eager to kill Hal Jordan. Sinestro promised him his time would come and led him to the Corps guardian, the Anti-Monitor, and they prostrated themselves before their master. 

(Green Lantern IV #21) - When Hal Jordan tried to recharge his ring using the Central Power Battery he found that the Sinestro Corps had booby trapped it. He was sent to Qward and confronted by Parallax / Kyle Rayner, who made Hal relive his father’s death, confronting the one fear he’d never faced. Parallax / Kyle told Hal that he’d always been cooler than him; he’d made the costume cool, the mantle cool. Hal knew Parallax was speaking as a parody of his friend, but Kyle prepared to engage him in battle. 

(Tales of the Sinestro Corps: Parallax #1) - Kyle paced inside the prison of his head, a prison he’d decided to have resemble his mother’s house, and he gazed at a painting he used to love as a child. His mother always told him she’d gotten it from a flea market, and it depicted a lost boy in the woods. He remembered how he and his mother used to make up stories about the lost boy, but right now he felt like that boy. He watched on helplessly as Parallax used his infected body to commit horrible deeds, and Parallax sent himself inside Kyle’s mind to reinforce his dominance over him. He saw that Kyle had made a series of portraits of his old flames, and Parallax taunted him because both Alex and Jade were dead, and he could have tried harder and saved them. They fought in Kyle’s mindscape, and Parallax dominated Kyle, convinced that he lacked the will to overcome his fear. Parallax promised the broken Kyle that after the Sinestro Corps prevailed against the GLC he’d find and kill everyone that Kyle cared about and make him watch. In a fit of rebellion Kyle used a pencil to stab Parallax in the eye. Parallax was stunned that he still had fight in in, but vowed that Kyle would stay under his control. After Parallax left Kyle;’s mind he turned over the painting and saw his mother’s signature, and realized she’d always meant it as a gift for him. Kyle was inspired to keep fighting against the parasite Parallax.
