(Green Lantern III #14-18) - Mosaic World, John Stewart tried to clear his head by playing jazz and ragtime on a piano, but was soon called to action when the Horde started an expansionist war against the human communities on the Mosaic. He used his power ring to isolate the Horde, and asked the Guardians to remove them from the Mosaic. They refused, they wanted to see how John would deal with the situation. After the Horde sprung a second attack on the humans John erected a giant mountain as a barrier between communities. The humans were angry with John because he refused to kill the aliens to ensure their safety. John was impressed with Rose Hardin, Hal Jordan's old friend, who saved an injured Horde member from being executed by her fellow humans. He took her back to his home, and over coffee they talked about their disparate backgrounds. John still didn't have a permanent solution to cease the Horde hostilities, but he refused to consider killing because he was still haunted by the deaths he caused on Xanshi. The humans of Hope Springs attacked Tomar-Tu and his delegation of peaceful alien races, resulting in the Xudarians declaring war on Hope Springs. John was sick of it all and erected giant barriers separating all the communities on the Mosaic. John started to hear the voice of the Old Timer in his head, and realized he'd inherited all of the Old Timer's memories because he was mind-linked to John when he died. John drifted toward madness when the Mosaic communities started tearing down his barriers and attacking each other. He snapped out of his madness, and with the help of Hal Jordan, Brik and Chaselon he quelled the revolt. He decided to build roads and find other ways to bring the races together. The Old Timer's memories gave him insights into the Guardians' plans for Mosaic. He suspected that while they could send the individual communities home they would not because they viewed it as an experiment. He talked to the Guardians and confirmed what he was thinking, but told him they would continue the Mosaic experiment regardless of whether or not John was there, so he might as well stay around to serve as Mosaic's protector.

John and Kyle tracked down Fatality, and John managed to blast her with green energy, a remnant of power he had from when Hal Jordan cured his body. Fatality went off planet and Kyle followed her, leaving John behind. Kyle defeated her and learned her vendetta against Lanterns started when her home planet Xanshi was destroyed because of the poor decision John Stewart made during the Cosmic Odyssey.

(JLA #77) - Mnemon, a synthetic lifeform that recorded history by draining the memories of others, landed on the moon and John Stewart and the JLA investigated. Atom entered Mnemon, who was quick to start eating the memories of the JLA. Mnemon’s actions always led to planetwide destruction, which it considered its’ own form of art. With Atom’s guidance Superman destroyed the magnetic field that kept it cohesive with his heat vision, but this freed the miniature black hole that powered Mnemon. Through great force of will Superman held Mnemon and the black hole in his hands long enough to fly into space and toss it into a wormhole.

(JLA #78, 79) - A large mass of Mirror Matter, previously thought to be only theoretical, was headed toward Earth, and John Stewart and the JLA disposed of it by having Firestorm transform it into marshmallow fluff. The JLA received an extraterrestrial video feed from Kylaq sent to them by Green Lantern Kyle Rayner, who was in deep space. The Peacemaker and his Paciforce deceed that Kylaq would join his forcesor perish. The JLA debated handling a political situation so far from Earth that they didn’t know all the details about. Wonder Woman said the JLA had a responsibility to nay innocents in danger, and Superman said that handling the Peacemaker was a preemptive measure, because he could eventually target Earth, so the JLA traveled to Kylaq. On Kylaq the JLA defeated the Paciforce and arranged peace talks between the Kylaq and the Peacemaker. The Kylaq introduced the JLA to their minister of defense Kanjar Ro. Peace talks broke down and the JLA fended off another assault by the Paciforce, but the JLA had to deal with the ruthless Kanjar Ro’s plan to enact a coup. They spread video footage of him torturing captured Paciforce members, and the Kylaq rejected his place in their government. The JLA sent Kanjar offworld.

(JLA #80-82) - The commune Safe Haven, an organization protected by metahumans, was at a standoff with government forces A.T.F. and D.E.O. that wanted to investigate the commune when the JLA intervened.

This went south when tensions led Haven members and government agents to fire at each other. An explosion seemingly killed everyone at the Haven, and the JLA were blamed. Superman, Major Disaster and Faith were all convinced that they were responsible, but Batman later examined the scene and found that no one had died. Axis America, led by Shepherd, aka Ubermensch, appeared to battle the JLA and revealed themselves as agents of Mr. Manson, the government operative behind Safe Haven who sacrificed it and used the metahuman the Mouth to convince the JLA they were responsible for hundreds of deaths. All this was so Manson could reclaim Faith for the U.S. government. Faith recognized the setup and forced Manson to leave her alone for the time being, and Axis America retreated.

(Superman / Batman #1, 3, 4) - President Luthor informed a number of heroes, including John Stewart, that a kryptonite asteroid was on a collision course with Earth. Luthor told them Superman was at fault and sent them to place Superman in federal custody. They battled, but Katana and Power Girl switched sides against their teammates. The fight led to Tokyo, which was nearly destroyed when Major Force exploded, and the explosion knocked out Luthor's team.

(JLA #84-89) - A wave of fear and remorse washed over the inmates of Arkham Asylum, the prisoners of Blackgate and President Luthor. John Stewart and the JLA investigated, and when Martian Manhunter, who’d rejoined the team after Scorch healed him of his fear of fire, tried to fix Luthor’s mind, he was assaulted by a powerful psychic force. Hostile nations and hate groups started feeling remorse and killing themselves. Firestorm’s powers were taken away, and realizing it was connected to world events, Manitou Raven guided the JLA to Vandal Savage’s mountain stronghold. Vandal recognized the world events as the attack of the Burning, a Martian he killed 20,000 years ago. He presented the Burning’s head to the JLA, and they brought Savage and the head to the Watchtower, only to discover Superman, who’d been attacked and bonded to the JLA meeting table. They freed Superman, but the revived Burning defeated the JLA and would have killed them if Major Disaster didn’t use evac protocols to teleport them to Superman’s Fortress of Solitude. Superman suspected that the Burning was actually Martian Manhunter, and in preparation of combating him they entered the Phantom Zone to ask the White Martians for aid. The Burning was already in the Zone and had slaughtered the Martians. The Burning again defeated the JLA, but they were saved and spirited away by Green Lantern John Stewart, who’d been briefed on the Burning and how to deal with it by the Guardians of the Universe. The Burning was a dangerous, chaotic race that the Guardians genetically modified to become Martians, and gave them an innate fear of fire so they couldn’t acess the powers of the Burning. When Manhunter overcame his fear of fire, his race memory turned him into the Burning, who needed fear and fire in multitude to asexually reproduce. Batman contacted the amnesiac Plas as his backup plan and convinced him to confront the Burning while Manitou contacted Martian Manhunter on the spiritual plane and found his soul dominated by the Burning. Burning unleashed nuclear attack to create the chaos and flames he’d need to asexually reproduce, but the JLA stopped the bombs, exceptfor one that hit Chongjin, North Korea, but Flash evacuated the population. Plas fought Burning to a deadlock because his mind was non-organic and not vulnerable to telepathy. Thanks to Manitou Martian Manhunter separated himself from the Burning, and Scorch sacrificed herself to sap the Burning’s flame. Manhunter confronted the Burning and destroyed him with his Martian-vision.

(JLA #91-93) - A meteor storm ripped holes in the JLA Watchtower, and Plas plugged the holes with his body as a stopgap until John Stewart and the JLA arrived to make repairs. The storm was caused by a rip in spacetime when an alien ship arrived near the moon. The JLA investigated and met the alien Pe-Paey, who told them he monitored Earth’s progress from time to time and needed to locate specimens of the silver-masked monkey. The JLA traveled with Pe-Paey to South America, but found a construction crew demolishing the monkey’s last habitat for grazing land. Superman spotted a silver-mask and tried to save it, but the crew’s explosives were already set and the blast killed the monkey, probably the last of its species. Pe-Paey was upset; his people’s Book of Lol predicted the silver-masks would become Earth’s dominant species. He asked to see all of Earth, and the JLA obliged, taking him to monuments, museums, an in the interest of full disclosure, and at Superman’s request, strife ridden countries like Santa Prisca and Minglia. The JLA foiled insurgents and terrorists in Minglia, and asked Pe-Paey what he thought. Pe-Paey assured them the silver-masks should have been the dominant species, and that humanity was choosing to become extinct, so he would help. He used his ship to bring meteors crashing toward Earth, but the JLA stopped any damage and told him their race was confused, not suicidal. Disheartened by the inaccuracies in the Book of Lol, the only thing he believed in, Pe-Paey returned to his ship and blew it up, killing himself.

(JLA #95-99) - Batman investigated a number of child abductions and murders that seemed to have a common perpetrator, and got the JLA involved. Manitou Raven had already learned that the Tenth Circle was responsible, so they spirited him away with vampire bats. Atom examined his telling stones at microscopic size looking for clues about where Manitou went, but soon after disappeared. They learned that most of the missing children possessed the metagene and could be powerful as a collective. Superman found children being taken into a van in Metropolis, and intervened, but the metahuman Nudge took control of his mind, and took him to her master Crucifer. Crucifer bit Superman, bringing him under his control, and sent him after his teammates. After defeating and abducting Faith Crucifer sent him back to the JLA Watchtower. Wonder Woman, in her research of the Amazon archives, matched a symbol found at the abductions to the Tenth Circle, a cult of vampires defeated by the Amazons in the early days of Greece. Superman surreptitiously destroyed the archives because they described how the Circle could be defeated, and lured Wonder Woman to Castle Crucifer. Superman attacked Wonder Woman, and Nudge, rebelling against Crucifer, tried to influence the battle, but when Superman briefly regained his senses Crucifer stabbed Wonder Woman with a sword. Crucifer dumped Wonder Woman on a highway, with the Tenth Circle calling card on her, a challenge for the JLA to oppose him. Batman didn’t want the team walking into a trap, and considered it misdirection. John Stewart had encountered the Doom Patrol while battling Tenth Circle members abducting more young metahumans, and the DP told him the Circle was their responsibility. Batman and the JLA went to the DP’s Key Mordaz hq to compare notes. Chief’s tech was able to find Atom in the telling stones, he’d found a side-door dimension that Crucifer used for transporting his cultists. The JLA and DP teamed up and confronted Crucifer in Barnes, Saskatchewan, where he prepared to transfer the souls of his vampire lords into the metahuman children he’d collected. The heroes drove him off, and Atom destroyed the vessel containing Crucifer’s heart he had stored in the side-door dimension. Crucifer was weakened enough for Superman to break Crucifer’s hold over him and destroy him.

(Flash II #208, 209) - John Stewart and the JLA summoned Flash to the JLA Watchtower, demanding to know why they no longer remembered his secret identity.

Larry Trainor restrained his Negative Man, Wormhole died fleeing from the JLA and being exposed to sunlight, and the JLA destroyed Crucifer’s mansion, which contained extradimensional doorways.

(JLA #100) - Manitou Raven sensed a disturbance in the Earth, and there were several volcanic eruptions, the hole in the ozone layer opened further, and other geothermal events signaled an extinction level event. Gaea, speaking through the earth-powered Major Disaster damned humanity for their abuse of her and their failure to get along. Sister Superior of the Elite v.2 had also realized that Gaea was ready to destroy humanity, and proposed a plan to John Stewart and the JLA, and although they doubted her trustworthiness they agreed. The Elite stormed Washington, demanded all governments dissolve and declared themselves rulers of Earth because humanity had proved themselves unfit to rule. After UN meetings and a staged defeat of the JLA by the Elite, every nation on Earth put aside their differences to tackle the Eelite. Gaea once again believed in humanity, seeing them unite against a common enemy, and held back her wrath.

(JLA #103) - John Stewart heard two calls for help from two apartments. He chose one and stopped a man from beating a woman, but when he responded to the second call he found the woman who yelled dead at the hands of her stalker. Stewart snapped and beat the man to death. His wrong decision reminded him of the planet he let die, and he worked nonstop fighting crime around the city, until he passed out from exhaustion. The JLA was there for him and he finally saw reason in Superman's argument that heroes did the best they could but weren't infallible.

(JLA #104) - Manhunter resumed his John Jones identity, taking a job at the Kennedy detective Agency. he was considered an excellent employee except for the fact that he was distant and made his co-workers uncomfortable. His boss had Detective Loony Linda try to learn more about them. John found her to be an intellectual, and she was interested in him despite his efforts to push her away. He gave his identity away by reverting to Martian Manhunter to save a woman from her abusive husband. John Stewart and the JLA, who were worried about Manhunter, visited his apartment, as did Linda. They all agreed that Manhunter pushed people away not because he felt uncomfortable, but because he had a hard time when he felt comfortable and friendly with people. Manhunter admitted that the wounds of his families death opened any time he felt anything for anyone.

(Enginehead #6) - Bones and the DEO were tracking new unpredictable metahuman Enginehead, who continually slipped away from them.

She went to Superman, and told him she remembered her mortality, and was in fear for her life, so Superman comforted her. They looked in on Joey, son of the superhero that died on Superman's watch and saw him demonstrating superpowers, tossing around playground bullies. The JLA met with Mrs. Abernathy and discovered her whole family gained super powers from a meteor during a fishing trip. She wanted the JLA to leave them alone, but they soon discovered she was using vigilante methods to uncover the improprieties that led to the destruction of the apartment building where her husband died. She was ready to kill the landlord when the JLA talked her down, making her realize that if she killed him she'd go to jail and her children would have lost both parents.

Although she found peace Joey still blamed Superman for his dad's death.

(JLA #111-114) - The Crime Syndicate of Amerika, who’d been posing as the JLA, revealed themselves and attacked the heroes. John Stewart and the JLA were battered and forced to retreat. The essential differences between the anti and positive-matter universes that prevented the Crime Syndicate from ever being victorious on the JLA’s Earth no longer applied after Krona tampered with the universe, meaning Earth was theirs for the taking. The JLA knew there only advantage was that the Syndicate was small because they had a tendency for in-fighting and back-stabbing, so the JLA would raise all their reserve members. Qwardians traveled to the positive-matter universe and blamed Earth for the reality altering wave Krona unleashed. They prepared to attck Earth with the doomsday weapon Erdammeru. The JLA and their reserves split into threee teams, one to fight the Qwardians, one to battle the Syndicate, and one to travel to the anti-matter universe to shake up the Syndicate’s Earth. Stewart was on the team that battled the Qwardians, and after fighting them to a standstill, the Syndicate, who’d been temporarily driven off Earth, arrived to pick off the weakened loser. Diataria Lysis was afraid of Qwardian leader Roval’s insatiable bloodlust, and brokered peace between Qward and Earth. The JLA informed the Qwardians that Krona was responsible for Qward’s destruction, and had been defeated by the JLA. The Qwardians returned to the anti-matter universe, but vowed to destroy the Crime Syndicate’s Earth for having dared try to invade their planet. Batman had planned for this to happen, and set his team on the anti-matter Earth into motion. The rest of the JLA entered the anti-matter universe, and forced the Syndicate to ask them for a favor, help in defeating the Qwardians. The Construct, who’d become an integrated being and was grateful to the JLA, contacted Flash and promised it could communicate with Erdammeru, the Qwardian doomsday weapon. Erdammeru still didn’t understand the concept of other and refused to make peace with the Construct, but their connection enabled John Stewart to absorb the weapon into his power ring, defanging the Qwardians. This was broadcast to the populace of anti-matter Earth, and when the people saw that the Syndicate was not invincible and began to rise up against them.

His savagery was winning the day until Martian Manhunter reappeared and flooded his brain with his own loss, the death of the entire Martian species.

(Green Lantern IV #14, 16, 17) - Hunger Dog contacted Loragg, telling him he was hot on Hal's trail, and asked him to call off the other bounty hunters. Loragg refused, and unbeknownst to John Stewart the Faceless Hunters that were also after Hal had sent him on a wild goose chase in hopes of collecting the bounty themselves. Hunger Dog eventually caught up to Hal, weak and exhausted after battles with the Faceless Hunters and Dominators, and after revealing himself to Hal put on a convincing show of taking his bounty. Amon Sur had him bring Hal to the southern California desert where Hal had buried his father. Amon ranted and raved until Hal baited him by calling him a coward. They fought, and Stewart dropped his pretense, joining the battle. At that moment Amon was teleported away by a yellow power ring sent by the Sinestro Corps, and Hal wondered exactly what Sinestro was doing with a Corps 

(Green Lantern IV #21) - The Corps began picking up the pieces after the assault on Oa, and Salakk realized that the Sinestro Corps were picking off Lanterns across the universe, leaving over 50 dead.  Stewart wanted the Guardians to come see them, figuring they at least owed them a pep talk.

(Green Lantern IV #24) - Sinestro communicated with Hal, Guy and John via his power ring as the Sinestro Corps invaded Earth.

He intended to makes saves of the Earthlings, and execute anyone who did not submit. Hal split from Guy and John to battle Parallax, who was attacking Coast City. As they fought Hal contacted Guy and John, asking them to find a painting done by Kyle’s mother that always made him feel close to her, hoping the sight of it would help him fight off the Parallax infection. Hal’s power ring ran out of energy, and he was absorbed into Parallax’s body, but this gave him a chance to talk to Kyle face to face. Hal’s support, coupled with the sight of his mother’s painting helped Kyle reject the Parallax infection. Parallax was ready to try and possess him again when Ganthet and Sayd appeared and split his essence into four pieces, imprisoning each one in a GL lantern. Guy, John, and Hal were now responsible for containing Parallax’s essence, and after Kyle stepped down as torchbearer and accepted a GL ring he was given the fourth GL lantern. The Sinestro Corps invasion of Earth was momentarily being fended off by Earth’s superheroes, but the GLC arrived on Earth to even the odds.
