History: 

(Tales of the Sinestro Corps: Cyborg-Superman #1 (fb)) - Henshaw's consciousness entered hyperspace, and he traveled from planet to planet, fashioning cyborg bodies for himself and terrorizing others, but failing to forget about Superman and his thirst for revenge. His wandering ended when he met Mongul, who also wanted to see Superman s annihilation.

(Superman: The Man of Steel #25) - Cyborg Superman and Mongul were targeting Metropolis as the next city they'd destroy to create a new Engine City. Superboy escaped his bonds, and left Engine City for Metropolis to expose Cyborg as a villain. Cyborg sent out a broadcast claiming the Last Son of Krypton had brainwashed Superboy, and that he was now a villain under his control.

(Superman: The Man of Steel #26) - Mongul's plans to build more Engine Cities and make Earth into a new Warworld was foiled when Superboy saved Metropolis from destruction and conversion into an Engine City. In revenge he activated Engine City so it would blast Earth out of orbit, although Cyborg disapproved of the change of plan. He left Mongul to battle Superman while he fought Steel, who found the fusion process engine that powered the city. Steel fended off Cyborg and kept Earth from going off orbit.

(Green Lantern IV #3, 13 (fb, BTS)) - Cyborg Superman became Highmaster of the Manhunters, and used captured Green lanterns thought to have died at Hal Jordan s hand to make new model Manhunters and to construct the artificial planet Biot. Grandmaster sent a Manhunter to Earth to destroy an obsolete previous model Manhunter. The Manhunters reported to Grandmaster that the Green Lantern Corps were attempting to reform, and he said he d let them, because they needed the power rings back on-line, and then no man would escape the Manhunters.

(Green Lantern IV #11-13) - Tomar-Tu escaped the Manhunters and piloted a ship towards Earth, crash-landing at Edwards Air Force base. The Corps ministered to his injuries, and Hal hoped that the other Lanterns he seemingly killed were still alive. He still felt tremendous guilt over his actions under the influence of Parallax. Hal and Guy traveled to Biot, and found the other Lanterns Hal thought he d killed being jailed by the Manhunters. Cyborg presented himself and warned Hal that he was only trying to bring order to the universe. Life entailed betrayal and pain, but by exterminating all life he could restore order. Cyborg and the Manhunters took down Guy, and used him as yet another Lantern to be incorporated into the Highmaster units. He tried to use nanotech Willhunters to subdue Hal, but Hal fought them off and revived the Lanterns he thought he d killed. He convinced them he was on their side, and they learned of the presence of more Corpsd members taken by the Manhunters for information and a connection to the Central Power Battery, including Arisia. Cyborg unleashed his Highmasters on the Lanterns, killing Kreon in the battle, and as the Lost Lanterns fought back Hal concentrated on freeing Arisia. Cyborg told Hal his connection to Oa let him see the things the Guardians were hiding from him, things that would change everything. He also revealed that he destroyed Coast City because that was his wife s home city. He could only bury his love and end his pain by destroying it. Hal and Arisia took over a Highmaster unit and used it to destroy Biot and the Manhunters, although Hal was positive the Cyborg could have survived. The Guardians were aware that Cyborg knew the secret of the 52 because he d melded with the Source Wall, and agreed to find his remains.

(Green Lantern IV #15) - A Guardian recovered the remains of Cyborg-Superman from Space Sector 3601, telling him he'd reveal everything he'd learned inside the Sector as well as his knowledge of the 52.

(Green Lantern: Sinestro Corps Special #1)   The Guardians interrogated Cyborg Superman, and found that he knew Earth was the secret to the stability of the 52 parallel universes, if it was destroyed, the entire multiverse would perish as well. They resolved that no one else learn of this, knowing full well that the Cyborg Superman would gladly destroy the multiverse to end the suffering and pain of life. Sayd feared that the Cyborg Superman was a sign that the Blackest Night would soon be upon them. Sinestro formed his Sinestro Corps and had his soldiers free Cyborg Superman and Superboy Prime from their sciencells, bringing them to Qward and introducing them to his master, the Anti-Monitor.

(Green Lantern IV #21) - Sinestro sent out and a number of his corpsmen across the space sectors to pick off Green Lanterns one by one, killing dozens. He promised Superboy Prime and Cyborg Superman that they would both get everything they desired, that fear would deliver it to them.

(Green Lantern IV #22) - As the Sinestro Corps waged war against the Green lanterns Cyborg prepared the completion of new Warworld and informed the Anti-Monitor that they would soon find his new home. He reflected that the Guardians had no idea of his true motives, and waxed poetic about the pain of life, and his belief that all life was only fear and loss. The Anti-Monitor soothed him, and promised him that if he fulfilled his wishes he would kill him. The Cyborg-Superman shed tears in gratitude.

(Green Lantern IV #23) - Cyborg announced to Sinestro that Warworld was ready, and waiting to attack the Sinestro Corps next target...Earth.

(Tales of the Sinestro Corps: Cyborg-Superman #1, Green Lantern IV #24) - Warworld approached Earth, and Sinestro laid out his plan of disabling the JlofA to Cyborg-Superman, and tried to get a rise out of him by mentioning the possibility of an encounter with Superman. Cyborg just mused that he was long past taunts, or wanting revenge, and he looked forward to pursuing his agenda of the end of all life and betraying Sinestro. Cyborg and his Manhunters entered Earth s orbit, but before making their play on the JlofA satellite he allowed himself a brief time to be alone and go over his past. He visited Earth and his wife s grave, thinking that he still yearned to be with her, not in reunion, but in oblivion so he could finally forget his pain. He dug up Terri s corpse and ripped it to pieces before returning to space. Cyborg and the Manhunters disabled the JlofA satellite by hooking into their defense systems, and Warworld made its way to Earth. Superman attacked the Cyborg, and their battle spilled over onto Earth. Cyborg said that he d be happy if he took Superman out before his life ended, but he would be equally pleased if Superman was the agent of destruction the Anti-Monitor promised him. The Sinestro Corps and the Anti-Monitor arrived on Earth, and began wrecking havoc.

(Tales of the Sinestro Corps: Superman-Prime #1) - Cyborg Superman was defeated by Superman. A blow flung him into the arms of Superboy-Prime, and he apologized for losing to his nemesis.

(Green Lantern IV #25) - The Sinestro Corps continued to wage war on Earth while Hal and Kyle went to Coast City to protect it from Sinestro, and Hal issued a radio broadcast asking the residents to flee. Not a soul left, everyone had faith Hal would save them from Sinestro. Sinestro and a number of his soldiers engaged Hal and Kyle, and Sinestro told them he d already won the war. His actions made the Guardians rewrite the Book of Oa, and now that the GLC could use lethal force they would be feared. Sinestro always wanted the GLC to be a more totalitarian police force to bring order to the universe, and he d succeeded. Sinestro and Hal s rings were both drained of power when they used inactive Manhunter power batteries against each other, and they squared off in hand-to-hand combat. Hal won, and told Sinestro he was under arrest. In NYC the Anti-Monitor tapped into Earth s energy and prepared to unleash an anti-matter wave to consume Earth. The GLC ruptured the heart of Anti-Monitor s Warworld, the Sinestro Corps central power battery, and created a shield around Warworld, Cyborg-Superman and the Monitor. Cyborg realized what was about to happen, and thanked the heroes for giving him a way to end his life. The ensuing blast nearly destroyed the Anti-Monitor, and he was finished off by Superman-Prime, who betrayed him for having destroyed his home, Earth-Prime. The Manhunters were deactivated with the destruction of Warworld, and Cyborg-Superman s remains were blasted into space. With the Anti-Monitor destroyed, Sinestro vanquished, and having no way of recharging their rings the Sinestro Corps fled Earth to lick their wounds. Manhunters found Cyborg s remains in deep-space, and requiring a Grandmaster, they reactivated him. Cyborg shed a tear when he realized he was still alive.
