Chapter Summaries

Mark and Mewtwo demonstrated plasma and nuclear fusion to Rayquaza, which used the knowledge to awaken a powerful Plasma Form. Rayquaza left for the sun to continue experimenting with its new form.

• Mark failed to teach Rayquaza Aura Power and instead guided it to sense microscopic particles with its Dragon-type power.
• Rayquaza learned to perceive atoms, and Mark and Mewtwo simulated nuclear fusion with deuterium and tritium, showing Rayquaza how plasma turned into golden flames.
• Mark and Mewtwo suppressed the fusion reaction, damaging the electron microscope, while Mark considered whether he could master the Great Sun True Fire.
• Rayquaza flew above Fallen Sky Mountain and tried to create plasma by intensifying its Dragon-type power and drawing on its authority.
• Rayquaza's black scales fell away as it transformed into a silver Ampharos-like Plasma Form, ionizing the sky for hundreds of kilometers.
• Rayquaza roared and headed to the sun because it could not yet perform nuclear fusion in its new form.

After Rayquaza vanished into the sun in its new Plasma Form, Mark and the Pokémon cleared the lingering silver plasma clouds and learned how Rayquaza’s lightning worked. Mark named the persistent, self-spreading current Eternal Thunder and considered giving some to Kakuna or Multi-Magnemite.

• Jirachi, Mew, and Hoopa searched the silver plasma clouds for Rayquaza but could not find it.
• Kakuna awakened and transformed into the World Devouring Worm, while Immortal Mark used Universe in the Sleeve to absorb the clouds.
• Mark explained that Rayquaza had developed Plasma Form through its understanding of nuclear fusion and had probably returned to the sun.
• Mark demonstrated a silver current that assimilated dust and continued growing, then named it Eternal Thunder.
• Mark considered feeding Eternal Thunder to Kakuna or Qiaonong · Multi-Magnemite instead of using it to make a magical artifact.

Mark and the Pokémon traveled to the Sun to find Rayquaza and test Mark’s Immortal body, but Mark realized he was still too weak to enter the Sun’s depths or travel between stars. Rayquaza emerged battered and ecstatic after mastering Nuclear Fusion, though its version behaved like an enormous Explosion and it had no idea how to control it.

• Mark and the Pokémon used Victini’s energy and their spatial abilities to reach the Sun, where Mark sensed Rayquaza deep inside but judged that he could not safely search for it.
• A Solar Flare erupted near Rayquaza, and Mark retreated while sensing that Rayquaza had been weakened and was heading toward him.
• Rayquaza arrived with its Plasma Form gone, its black armor badly damaged, and one horn broken, then told Mark it had learned Nuclear Fusion in the Sun’s Core.
• Rayquaza explained that its first Nuclear Fusion attempt caused a massive explosion that it believed could have destroyed Earth Star.
• Mark asked whether Rayquaza could control Nuclear Fusion’s power, but Rayquaza was confused and assumed the process naturally burst out all at once.

Mark taught Rayquaza that mastering nuclear fusion meant controlling atomic nuclei directly, then explored the Sun and the Solar System’s outskirts with his Pokémon. On the way back, he checked on Kyogre at Neptune and visited Groudon on Saturn, where Groudon still had not learned to fly.

• Mark explained that Rayquaza needed to learn to split protons and neutrons to master nuclear fusion, and Rayquaza understood.
• Jirachi, Xerneas, Celebi, and the other Pokémon repaired Rayquaza’s battered body, and Mark explored the Sun with them.
• Mark, Rayquaza, and Jirachi used Victini’s Infinite Energy to reach the Solar System’s boundary and found more comets than the Radio Telescope had recorded.
• Mark visited Kyogre on Neptune, found that it had grown larger, and estimated it would master Neptune in less than a month.
• Mark traveled to Saturn to check on Groudon and found that it had mastered some of Saturn’s power but had made no progress toward flying.

Mark found a Heatran beside the two Groudons in Saturn, but could not uncover how it had appeared. He taught Groudon to fly, while the Rainbow R Organization learned its Heatran operation had failed and heard that Mark had led the successful Xerneas Revival Project.

• Mark and the Pokemon reached Saturn's core, where he discovered a third Pokemon, Heatran, beside the two Groudons.
• Groudon told Mark that Heatran had suddenly appeared while Groudon was deepening its control over Saturn and thinking about flying.
• Mark could not divine the origins of Heatran or the smaller Groudon, then enlightened Groudon and enabled it to fly as a Shiny Pokemon with wings.
• The Rainbow R Organization restricted and transferred its files on the OTZ404 Parallel Timeline after declaring it explored.
• A silver-haired young man and Doctor Rein discussed how Heatran remained alive but had sent no news, and learned that their next operation was expected in half a month.
• Doctor Rein told the silver-haired young man that Mark had led the revived Xerneas Revival Project to success.

Mi Yang ordered the Rainbow Guard to recruit Mark and Red Fire, reprimanded Black for demanding Ideal Land’s newly bred Xerneas, and arranged compatibility-testing slots through Doctor Noah. After hearing an update about the Star Alliance and Groudon, Mi Yang received news that prompted him to open his Spirit Control Panel.

• Mi Yang told Doctor Rein to offer Mark a top-tier researcher position and access to Guard research, while ordering Red Fire recruited as an elite member.
• Mi Yang summoned Black, slapped him for trying to seize Ideal Land’s Xerneas, and let him keep his badge after warning him not to repeat the offense.
• Mi Yang asked Doctor Rein to contact Doctor Noah and arrange Xerneas compatibility-testing slots for Rainbow Guard members.
• A subordinate told Mi Yang that Blue Enchantress had joined the Star Alliance and that the group planned to search for Groudon in a Parallel Time-Space.
• A researcher whispered news to Mi Yang, who opened his Spirit Control Panel.

Mi Yang approved Corey’s plan to establish a base in the OTZ404 Parallel Timeline’s Ultra Space and use Necrozma to help retrieve Groudon and Kyogre. As Corey began the operation, Mark enlightened Calyrex and Zacian on Mars, and Zacian asked when Mark became an immortal.

• Mi Yang learned that the cheat-panel countdowns might return to normal in about three days, then heard Corey propose a new plan for the OTZ404 Parallel Timeline.
• Corey presented a detection report showing that the timeline’s Ultra Space was stable and Necrozma was dormant, and explained how new technology had let him obtain it.
• Corey proposed building a base in Ultra Space and temporarily controlling Necrozma to help retrieve Groudon and Kyogre, and Mi Yang entrusted the operation to him.
• Corey gathered personnel and set out for the OTZ404 Parallel Timeline while Mark arrived at Calyrex’s Coffee Garden on Mars.
• Mark enlightened Calyrex and Zacian, and Zacian asked when Mark had become an immortal.

Mark demonstrated his sage power to Zacian and learned more about Fairy-type power while helping Calyrex grow coffee on Mars. Calyrex urged Zacian to confront its lingering desire to defeat Eternatus, and Zacian became Mark's Pokemon so it could train; as they prepared to return, Mark sensed something unexpected.

• Mark showed Zacian his sage power, gaining new insight into Zacian's and Calyrex's abilities.
• Calyrex revealed its plan to spread life across Mars and showed Zacian an animation of it defeating Eternatus, explaining that it hoped Zacian would find happiness by facing its old enemy.
• Zacian admitted it still wanted to defeat Eternatus and asked to train with Mark, who captured it in a Pokeball.
• Groudon tried to offer Zacian flying lessons, but Zacian floated into the air on its own, prompting Groudon to fly away in frustration.
• Mark called the Pokemon to return and suddenly sensed something unexpected.

Mark discovered that Butterfree had become a Legendary Pokemon with the power to travel through long-distance Dream Channels, enabling plans for interstellar exploration. Meanwhile, Corey’s team prepared to control Necrozma in Ultra Space, but Necrozma awakened ahead of schedule as the tournament countdown vanished.

• Butterfree emerged from a dream entrance after absorbing dream power and became a Legendary Pokemon with Dream Channel authority.
• Mark realized Butterfree could establish dream coordinates and chose Proxima Centauri as the first destination for his interstellar journey.
• Corey and more than a dozen Rainbow Guard members established a base in Ultra Space, gained the residents’ trust, and located sleeping Necrozma.
• Corey delayed controlling Necrozma until after the annual transmigrator competition, while he and his team watched their cheat-panel countdown reach its final seconds.
• The countdown disappeared, and a researcher reported that Necrozma had awakened ahead of schedule.

Corey investigated Necrozma’s rising energy and found that it had awakened only partially, with at least two hours before it fully awakened. After learning the Guard could no longer access the cheat-panel league, he sent his team to suppress the Crystalline Cores and secure Ultra Megalopolis.

• Corey hurried to the monitoring station after a researcher reported that Necrozma had awakened early.
• Corey checked the readings and determined Necrozma had not fully awakened, though it would do so in about two hours.
• The Rainbow Guard members asked about the missing league countdown, and Corey told them the Guard had lost access to the competition.
• Corey ordered Qin Chuan, Beta, Nothman, and Zhao Guan to suppress the Crystalline Cores at their assigned locations.
• Corey told Zheng Zheng to accompany him and sent the other nine Guard members toward Ultra Megalopolis to keep people away when Necrozma rampaged.

Corey tricked Zheng Zheng into helping him unleash a hidden Necrozma and restore its power by feeding it another Necrozma, Solgaleo, and Lunala. The empowered Necrozma sensed an even greater source of light and raced through space, leaving Corey to pursue it into the Chaos Space in the Desert of No Return.

• Corey sent the Rainbow Guard members away and secretly took control of Zheng Zheng with a mechanical helmet, then prepared Lunala’s Pokeball.
• Corey released his hidden Necrozma and directed it to draw out and devour the sleeping Necrozma underground.
• The awakened Necrozma absorbed Solgaleo and Lunala, briefly transformed into Ultra Necrozma, and regained some of its lost strength.
• Necrozma sensed a powerful light and tore through space, briefly confronting Eternatus before it fled.
• Corey pursued Necrozma on Lugia and followed it into the Chaos Space in the Desert of No Return northwest of Xia.

Corey followed Necrozma through the scorching, empty Chaos Space as it pursued a mysterious light, then a devastating blast struck them. The chapter ended with Corey blown away by the shockwave, injured and barely conscious.

• Corey found the Chaos Space unusually hot and devoid of Pokemon.
• Necrozma ignored Corey and walked toward a light it wanted to consume, breaking through Lugia’s ice wall.
• Corey used the Ultra Beast Control Instrument on Necrozma but could not stop it, so he followed it deeper into the Chaos Space.
• Corey noticed the ground had turned into ceramic as the temperature rose above one hundred degrees.
• A blinding flash and mushroom cloud appeared on the horizon, and Corey recognized them as signs of an atomic bomb.
• The shockwave tore through Corey’s protective suit and hurled him away before he could protect himself with Lugia.

After an atomic blast freed Lugia from Corey's control, Jirachi rescued the battered human and told Lugia about Rayquaza's hydrogen bomb experiments and its clashes with Eternatus. The two returned to the Chaos Space, where a strange Pokémon resembling a fusion of Rayquaza and another Pokémon appeared.

• The explosion damaged Corey's Mind Control Device, freeing Lugia, who chose to leave Corey alive and fly away.
• Jirachi found Lugia and warned him about Eternatus, but Lugia flew into Eternatus's territory before Jirachi brought him back to the Chaos Space.
• Jirachi told Lugia that Rayquaza had been practicing hydrogen bomb explosions and had repeatedly driven Eternatus away.
• Jirachi asked Lugia about Corey, but a clear Dragon Roar interrupted them.
• Jirachi and Lugia saw a strange Dragon-type Pokémon resembling a fusion of Rayquaza and another Pokémon circling overhead.

Lugia recognized the golden, crystal-armored Pokémon in the sky as Necrozma, which had devoured Rayquaza and taken a new form. The apparent threat vanished, and Rayquaza emerged in a smaller body, while Jirachi focused on posing for a photo and hiding their secret training from Mark.

• Lugia explained to Jirachi that Necrozma had devoured Solgaleo, Lunala, and Rayquaza, becoming Necrozma, Light of Rayquaza.
• Lugia tried to leave with Jirachi, but Jirachi praised the new form's name, and a voice from behind agreed.
• Lugia turned and saw a small, golden, crystal-armored Rayquaza as the giant Necrozma in the sky disappeared.
• Jirachi summoned a mirror, posed with Rayquaza, and persuaded Lugia to take their picture.
• Jirachi decided not to send the photo to Mark because it might reveal that Rayquaza had been secretly practicing Hydrogen Bomb Explosion near Clear Stream Village.

Jirachi and Rayquaza confronted the crazed Necrozma, and Rayquaza battered it until it released Solgaleo and Lunala. Jirachi healed Necrozma, which calmed down when Rayquaza returned, and Jirachi ended by asking Lugia whether Necrozma could merge with it too.

• Jirachi failed to send a photo because Rayquaza's Hydrogen Bomb Explosion had destroyed the Desert of No Return's communication base stations, so it used Small Wish to send it instead.
• Rayquaza removed the Crystal Armor, revealing Necrozma, which became fixated on Rayquaza's Eternal Light and lunged at him.
• Rayquaza transformed into Mega Rayquaza and struck Necrozma repeatedly with Dragon Ascent: Rainstorm, forcing it to release Solgaleo and Lunala.
• Jirachi moved Lugia and the unconscious Corey to safety, then used Wish to heal Necrozma, which absorbed Solgaleo and Lunala again.
• Necrozma calmed down when Rayquaza returned, and Jirachi asked Lugia whether Necrozma could merge with Jirachi.

Jirachi explained her theory that she could merge with Necrozma, then played with Mew while Rayquaza kept Necrozma under control. Lugia remained confused and ended up signing autographs after Hoopa told him it could boost his popularity.

• Jirachi told Lugia that she was a Cosmic Pokemon who represented comets and might be able to merge with Necrozma.
• Hoopa and Mew tried to inspect Necrozma, then Jirachi and Mew began a powerful bout of playful fighting.
• Necrozma grew greedy after sensing Jirachi's light, but Rayquaza arrived and kept him subdued.
• Hoopa wrote autographs to become more popular and gave Lugia a pen and paper to sign.
• Lugia wrote two autographs before wondering what he was doing.

Lugia watched Jirachi and the others conduct increasingly bizarre fusion experiments with Necrozma, eventually seeing Jirachi fuse successfully before he tried again with Nihilego nearby. The experiments stopped when Jirachi invited Lugia to watch Pikachu Agent 007 and warned him not to tell Mark about their activities or the sleeping Corey.

• Lugia watched Jirachi and Mew repeatedly fight and make up, then saw Jirachi assemble borrowed arms and an unconscious Super Jirachi for failed fusion attempts with Necrozma.
• Jirachi finally fused with Necrozma alone, forming Necrozma - Dream Shine, but ended the fusion because he could not control it and disliked its appearance.
• Jirachi began another fusion experiment with a Nihilego carrying two Cosmoem and a Zygarde Core, while Mew handed the three Pokémon to Lugia.
• Rayquaza restrained Necrozma as Jirachi's collisions cracked its Crystal, released Solgaleo, and briefly revealed Lunala before Jirachi repaired Necrozma with Wish.
• Jirachi stopped the experiments and invited Lugia to watch Pikachu Agent 007, then warned him not to tell Mark about the fusion tests or the Hydrogen Bomb Explosion practice.
• Jirachi pointed out the sleeping Corey and suggested leaving him at the gym until they were exposed.

Lugia arrived in the main world expecting a dangerous landscape, but found Fallen Sky Forest and a peaceful town where Pokémon were commonplace. As it followed Jirachi and the others through Clear Stream Village's night market, it saw Hoopa Confined fail to get itself banned from an ice cream shop.

• Lugia emerged from the Chaos Space and learned from Jirachi that Groudon had recently learned to fly and was streaking across the sky.
• Jirachi showed Lugia Calyrex's coffee garden through an astronomical telescope, then led the Pokémon toward Clear Stream Village.
• Lugia entered the busy night market and saw vendors warmly serving Jirachi and Mew, while an ice cream shop displayed signs banning both of them.
• Hoopa Confined approached the ice cream shop and prepared to smash its glass, but the bearded shopkeeper's glare drove it away.
• Mew explained that Hoopa Confined wanted to get onto the shop's banned list, though its previous attempts had failed.

Lugia joined Jirachi and the others at Clear Stream Gym, where they explained their admiration for Pikachu 007 and interrogated Corey about the Rainbow R Organization. Meanwhile, Sun Jun returned to Clear Stream Town after failing to find Groudon, only for Groudon to appear right in front of him.

• Shaymin collected one of Lugia’s shed feathers and buried it to save for a future meal.
• Lugia followed the Pokémon to Clear Stream Gym and watched Pikachu Agent 007 with them, then asked why they admired the character.
• Jirachi explained that the Pokémon trained to manage their weaknesses, invited Lugia to train, and forced Corey to drink Memory Potion during an interrogation.
• Sun Jun recalled how he and his companions failed to locate Groudon, the Star Alliance abducted Lan Sanji, and he escaped with Shi Xiaoling’s help.
• Groudon descended into the Garbage Dump and asked the startled Sun Jun whether he needed something.

Sun Jun encountered the Shiny, winged Primal Reversion Groudon in Clear Stream Village, then learned from Shaymin that Groudon had been on Saturn and that the Rainbow R Organization’s Ancient Revival Plan was already documented. Sun Jun realized Shaymin and Clear Stream Gym likely knew far more about the conspiracy than he did, and he broke down crying.

• Sun Jun watched Groudon fly away and regretted missing the chance to photograph it, then wondered whether the Rainbow R Organization’s Ancient Revival Plan had succeeded.
• Shaymin appeared beside an unconscious person and explained that Groudon had been flying around Clear Stream Village since returning from Saturn.
• Sun Jun learned from Shaymin that Groudon had been on Saturn, then prepared Shaymin a muddy drink.
• Sun Jun asked Shaymin about the Ancient Revival Plan, and Shaymin described the plan and showed him the Rainbow R Organization’s detailed report.
• Sun Jun asked whether Clear Stream Gym knew about the plan, and Shaymin said they probably did before noticing Sun Jun was crying.
