Chapter Summaries

Caterpie discovered that its reflexes and physical abilities had improved after waking, but it had also forgotten how to use Psychic to fly and how to swim. Mark entered the Battle Arena with Caterpie as his first Pokemon, where Caterpie sank into the water at the start of its match against Luo Lan.

• Caterpie asked Jirachi and Mew to attack so it could test its new ability to dodge, and the three played together as Jirachi and Mew made up.
• Mark stopped Celebi from reversing the crater Jirachi had made and noticed that Caterpie could keep pace with Jirachi and Mew without using special abilities.
• Mark asked about Caterpie's Psychic, and Caterpie realized it had forgotten how to Levitate after repeatedly failing to fly, even in its transformed forms.
• With only minutes before the match, Caterpie urged Mark to head to the arena, and the tournament staff directed him to Corridor No. 4.
• Mark's Pokemon passed inspection, the Battle Arena became a flooded swimming-complex field, and Caterpie struck a pose before sinking and flailing because it had forgotten how to swim.

Mark sent Caterpie into the Ocean Battle Arena, where it appeared to struggle underwater, while Luo Lan's Dolphin Hero circled it without attacking before returning to its Poké Ball. Mark recognized that Dolphin Hero had a special mechanic, but the reason for Luo Lan's actions remained unclear.

• Mark sent Caterpie into the seawater, and the audience watched it thrash underwater as commentators questioned whether it could swim.
• Luo Lan sent out Dolphin Hero, which swam around Caterpie instead of attacking.
• Xiao An explained that Dolphin Hero was a Water-type Pokémon from the Azure Plains and noted its apparent disadvantage in strength against Caterpie.
• Luo Lan waited until Dolphin Hero nodded, then recalled it to its Poké Ball, baffling the spectators and commentators.
• Mark recognized Dolphin Hero as a Pokémon with a special mechanic.

Luo Lan’s Dolphin Hero transformed into Dolphin Hero Superman and overwhelmed Caterpie, which had forgotten how to fight using its learned moves. As Caterpie let its subconscious take over, it sensed a new technique in its bloodline: Ten Thousand Styles.

• Luo Lan recalled Hydreigon and sent Dolphin Hero back into battle, transforming it into Dolphin Hero Superman.
• Dolphin Hero Superman’s Hydro Pump appeared to blast Caterpie, but Caterpie had dodged across the arena and surfaced in midair before falling back into the water.
• Dolphin Hero Superman struck Caterpie with a powerful three-hit combo, and Caterpie countered the final attack with a headbutt.
• Caterpie realized it had forgotten how to swim, fly, enter its Activated State, and use its moves, so it fought with ordinary strikes while its subconscious took over.
• As Caterpie continued fighting and adapted its movements, it sensed a new bloodline technique called Ten Thousand Styles.

Caterpie struggled to understand the Ten Thousand Styles it had sensed in its bloodline, but Mark urged it to let its body fight by instinct. Caterpie began chaining unfamiliar techniques against Dolphin Hero Superman, ending with a fierce aerial attack as the battle continued.

• Caterpie neutralized Dolphin Hero Superman's Giga Impact with Ten Thousand Styles - See Through, then forgot how to use the technique.
• Mark told Caterpie to stop thinking about the moves and let its body act on instinct.
• Caterpie unexpectedly used Ten Thousand Styles - Teleport to appear in front of Mark, then flew back toward Dolphin Hero Superman.
• Dolphin Hero Superman struck Caterpie with Liquidation (Meteor Hammer), but Caterpie began attacking with repeated Extreme Speed and Teleport.
• Caterpie built up speed and drove Dolphin Hero Superman downward with Ten Thousand Styles - Seismic Toss, Ten Thousand Styles - Body Slam, and Ten Thousand Styles - Destructive Beam Machine Gun.

Caterpie defeated Dolphin Hero with powerful Ten Thousand Styles attacks, then healed it and celebrated before seemingly losing control of its body and abilities. Caterpie evolved through shifting black, white, and green cocoons, emerging as a winged, muscular Pokémon that immediately began posing for the crowd.

• Caterpie slammed Dolphin Hero into the seawater, crushed the arena with a green-aura hill, and swept the battlefield with a Destructive Beam Machine Gun.

• Caterpie evolved through shifting black, white, and green cocoons, then emerged as a winged, muscular Pokémon and flexed in midair.

Mark sent Zapdos into the damaged Ocean Battle Arena to face Luo Lan’s mutated Goodra. Zapdos struck before Luo Lan could give a command, activated Primal Form, and ended the battle amid an electromagnetic storm that disabled the arena’s electronics.

• After examining the damaged arena, the referees ruled that Mark and Luo Lan’s match would continue there.
• Kakuna returned to Mark and retracted its muscular limbs and wings before Mark recalled Caterpie.
• Mark sent his larger, imposing Zapdos into the arena, and Luo Lan answered with his mutated Dragon- and Steel-type Goodra.
• Before Luo Lan could finish speaking, Zapdos struck Goodra with Thunder Kick · Divine Bird Charge and seized its head in its talons.
• Zapdos activated Primal Form, unleashing a lightning storm that disrupted the arena’s electronics as the battle ended.

After Mark’s Zapdos defeated Luo Lan’s Goodra, Mark’s Pokémon appeared in a lively interview and autograph event. Back at Clear Stream Gym, Jirachi woke Kakuna and discovered it could grow three Caterpie heads and six muscular arms.

• Luo Lan surrendered after Zapdos defeated Goodra, and Mark’s Pokémon greeted the spectators.
• Mark joined Xiao An’s interview and discussed Titan Caterpie and Rayquaza with Professor Zuo Lun.
• Hoopa finished preparing autographs for the studio and began writing more to attract attention.
• Mark explained to Jirachi and Mew that Kakuna was sleepy because it was preparing to evolve, then allowed Jirachi to wake it.
• Kakuna grew a Caterpie head, then two more heads, and finally four additional muscular arms at Jirachi’s request.

Jirachi’s excited requests made Kakuna grow thousands of Caterpie heads until they exploded, but Kakuna emerged unharmed. Mark investigated Kakuna’s apparent lack of pain and found that it felt pain when a piece of its flesh lost its vitality.

• Jirachi asked Kakuna to grow more heads, and Kakuna produced an ever-expanding mass of Caterpie heads that overwhelmed the room and disrupted Hoopa Confined’s abilities.
• The heads exploded and their flesh returned to Kakuna, which quickly recovered and formed a new Caterpie head.
• Jirachi apologized and used Wish and Healing Wish on Kakuna, while Kakuna said it had not been hurt by the explosion.
• Kakuna tore off its own head and regenerated it to demonstrate that it could not feel pain, and Mark explained that it had not been injured.
• Mark compressed a piece of Kakuna’s flesh with Aura and Fighting-type power until it lost vitality, and Kakuna confirmed that it felt pain.

Mark discovered that Kakuna had gained a powerful interference Ability and a new Ten Thousand Styles transformation power after evolving. Kakuna then realized its Primeval Chrysalis and Final End Chrysalis forms had evolved too, and flew outside to test its new giant form.

• Mark explained that Kakuna's new Ability could interfere with opponents' moves, and Kakuna demonstrated transformations that imitated Pokemon and simple objects.
• Mark distinguished Kakuna's shape imitation from Mew and Ditto's genetic transformation, explaining that Ten Thousand Styles expanded Caterpie's earlier Hundred Styles.
• Kakuna successfully transformed into various Pokemon and objects but failed to imitate Legendary and Mythical Pokemon, intricate electronics, and its Primeval Chrysalis and Final End Chrysalis forms.
• The Caterpie head realized those chrysalis forms had evolved after Kakuna's battle and evolution, so Kakuna flew behind Clear Stream Gym and transformed into a nearly hundred-meter-long Ten Thousand Styles World Devouring Worm.

Caterpie transformed into the World Devouring Worm, but initially lost control of its violent bloodline and threatened Clear Stream Gym. Mark and the others helped it regain control, then the little ones began exploring and pestering its enormous body.

• Mark used Analysis and identified the transformed giant insect as a Bug- and Dark-type World Devouring Worm, though he could learn little else about it.
• The World Devouring Worm rampaged, so Mewtwo Z raised mental barriers to protect the area; Victini and Jirachi reinforced the defenses.
• Mark touched the World Devouring Worm's forehead, helping it calm down and gain initial control over its violent bloodline.
• The World Devouring Worm explained that its transformation had left it dazed and driven to rampage, and Mark told it to keep strengthening its control.
• Jirachi and Mew slid and played across the World Devouring Worm while Jirachi dragged Leafeon into its mouth for an expedition, and little Mew gnawed on one of its feet.

Mew unconsciously ate the World Devouring Worm’s armor and transformed into a smaller copy, while Kakuna tested its control over the worm form. Rayquaza appeared over Clear Stream Village and issued a territorial warning, then attacked Jirachi in Fallen Sky Forest, where Jirachi shielded Leafeon.

• Mark discovered Mew chewing through the World Devouring Worm’s foot armor, and Mew ate its flesh and transformed into a smaller World Devouring Worm.
• Mark asked Kakuna about its worm form, and Kakuna said it could transform into a Final End Chrysalis form only after returning to Kakuna.
• Rayquaza appeared above Clear Stream Village as Kakuna prepared to transform, and the two Pokémon gathered energy before Rayquaza flew away.
• Kakuna told Mark that Rayquaza had warned them that the sky was its territory, and Mark realized Jirachi and Leafeon were missing.
• Mark found Jirachi dazed in Fallen Sky Forest beside a tearful Leafeon, and realized Rayquaza’s attack had targeted them while Jirachi shielded Leafeon.

After Rayquaza attacked Jirachi, Mark realized their group was now strong enough to fight back and decided to capture Rayquaza after the World Youth Trainer Competition. He returned to Clear Stream Village with Jirachi, Mew, and Leafeon, where Kakuna had transformed and two familiar figures appeared in the sky.

• Mew woke Jirachi, and Mark healed Jirachi after Rayquaza's attack while explaining that Rayquaza had already left.
• Jirachi recalled that Rayquaza's Lock-On had prevented it from dodging, but its body had mostly recovered from the attack.
• Mark concluded that their group could withstand Rayquaza's attacks and decided to capture it after the World Youth Trainer Competition, promising not to force Jirachi to fight.
• Mark summoned Venusaur to restore the damaged forest, then flew back to Clear Stream Village with Jirachi, Mew, and Leafeon.
• Mark found that Kakuna had completed its transformation into the Final End Chrysalis form, while two familiar figures appeared in the sky.

Kakuna transformed into the World Destroying Worm, a mechanical silver form that appeared after Rayquaza confronted its World Devouring Worm form. After explaining the transformation to Mark, Kakuna reverted to its cocoon and fell asleep, while Doctor Zhou Tong asked Mark about Rayquaza and the connection between Jirachi and the Draconids.

• Mark identified Kakuna's new silver form as the Bug- and Psychic-type World Destroying Worm, while Jirachi and Mew climbed over it.
• The World Destroying Worm told Mark that it had regained control of its body after transforming and described the changes to Butterfree, who had trained with Cresselia.
• Cresselia avoided Mark's questions about what Butterfree had helped her with, then returned to the Dream World with Butterfree.
• After briefly describing its new body, the World Destroying Worm collapsed into fragments that gathered back into Kakuna, which began snoring despite appearing lifeless.
• Doctor Zhou Tong asked Mark about Kakuna's transformations and Rayquaza's appearance, and Mark suggested Rayquaza had been defending its territory.
• Doctor Zhou Tong said he knew of no connection between Jirachi and Rayquaza, but said Rayquaza's secret was rumored to involve the Draconids near Sky Pillar Mountain.

Mark discussed the Draconids and the Chaos Space near Sky Pillar Mountain with Doctor Zhou Tong, then revealed that he planned to capture Rayquaza after the World Youth Championship. He demonstrated that he could fly beyond the atmosphere unaided, leaving Doctor Zhou Tong stunned.

• Doctor Zhou Tong told Mark that the Draconids likely lived in a Chaos Space near Sky Pillar Mountain in every Parallel Time-Space, and that the Draconids or the Rainbow R Organization's archives might hold clues about Rayquaza and Jirachi.
• Mark asked Celebi whether it had traveled through time near Sky Pillar Mountain, and Celebi said it knew neither the Draconids nor Sky Pillar Mountain.
• Mark said he planned to find the Chaos Space with Rayquaza and capture Rayquaza after the World Youth Championship through a battle, while Victini, Mew, Zapdos, and Mewtwo showed their fighting spirit.
• Doctor Zhou Tong worried about how Mark would survive a battle with Rayquaza in outer space, and Mark shot into the sky before returning to demonstrate that he could stay outside the atmosphere for hours without breathing.
• Mark acknowledged that Rayquaza would have an advantage in zero gravity and said he needed a strategy, while Doctor Zhou Tong stared at him in disbelief.

Mark learned about upcoming Legendary Pokemon crises and the plans he needed to make, then returned to Bere City for the World Pokemon Alliance Youth Trainer Competition semifinals.

• Mark fought Mewtwo, and Doctor Zhou Tong realized Mark's inhuman strength explained why Ling Huan's ambush had failed.
• Mark questioned Doctor Zhou Tong about Legendary Pokemon and learned about the awakenings of Groudon, Kyogre, the Black and White Dragons, and other Legendary Pokemon.

• Mark rested overnight, returned to Bere City, and arrived at the Giant Shell Battle Arena as the semifinals were about to begin.

Mark and Aya began their semifinal at the World Pokemon Alliance Youth Trainer Competition, where Aya requested a specific opening matchup to train her Lucario. The chapter left them preparing to battle, with Aya still confident that her other Pokemon could win a round.

• Commentator Xiao An introduced Mark and Aya’s semifinal and explained their shared ties to the Hia Kingdom, Hack Pokemon Academy, and Clear Stream Gym.
• Dean Cao joined Xiao An’s commentary and recalled how a defeat by Amon had nearly made him give up being a Trainer.
• The arena screen revealed that Mark would use his six remaining tournament Pokemon, while Aya’s team included her newly evolved Blastoise.
• Aya approached Mark before the match and asked to send out Lucario against Golisopod instead of Victini.
• Mark questioned why Aya wanted Lucario to face Golisopod, and Aya said the matchup would provide better training while her other Pokemon might still win.

Aya challenged Mark to a battle between her Lucario and his Golisopod, declaring that she would defeat one of his Pokémon. Their opening exchange featured Aura clashes, feints, and Substitutes, and the chapter ended as both Pokémon began Bond Evolution.

• Mark and Aya's rainbow light bands appeared as Golisopod and Lucario began Bond Evolution.

Aya’s Lucario and Mark’s Golisopod underwent Bond Evolution and fought at such speed that spectators and commentators could barely follow the battle. Just as Dean Cao released Dragonite to judge their evenly matched fight, a flash of Aura revealed that the two Pokémon had decided the victor.

• Lucario and Golisopod underwent Bond Evolution, taking on new forms equipped with weapons.
• The two Pokémon exchanged attacks across the Battle Arena, leaving spectators unsure who had the advantage.

• Dean Cao released Dragonite to assess the battle, but a flash of Aura appeared before it could report back.

Mark’s team defeated Aya’s team in the semifinal, advancing to the finals after Golisopod narrowly beat Lucario and the remaining matches ended in Mark’s favor. The chapter left Mark and his Pokemon celebrating in Bere City as they waited for the final in two days.

• Mark sent out Victini, which defeated Aya’s Mega Gyarados with a V-Create Infinite despite the type disadvantage.
• Vikavolt Multi-Magnemite defeated Raichu, Nihilego beat Gyarados, and Spectrier defeated Charizard after Glastrier took a Blast Burn (Storm).
