Chapter Summaries

Yuko explained that Deoxys had trapped LaRousse City and disabled its systems, and Gary suspected it had come because of the meteorite she and Dr. Lund had studied. After gathering food and locating the captured people, the group slept in the laboratory, where a strange noise woke them the next morning.

• Yuko led Gary, Ash, and the others to Dr. Lund's laboratory and explained that Deoxys had sealed LaRousse City off and shut down its systems.
• Yuko said Deoxys had originated from a North Pole meteorite and that she and Dr. Lund had studied a related meteorite, prompting Gary to suspect it had drawn Deoxys to the city.
• Plusle, Minun, and Munchlax came through a ventilation shaft, and the group postponed investigating the meteorite to find food.
• Gary, Ash, Brock, and Shota carried a food vending machine back to the laboratory, while Arlon, Shota, and Hitomi found where Deoxys was holding people.
• The group ate, made beds on the laboratory floor, and went to sleep; a strange noise woke them the next morning.

Gary and the others escaped Deoxys's clones and reached the underground research institute, where Yuko revealed that the Crystal Body contained a second Deoxys. After Gary explained how the two Deoxys and Rayquaza came to LaRousse City, the group agreed they needed to revive the Crystal Body Deoxys, but the institute's backup power could not do it.

• Gary led the group to the underground research institute while Deoxys's clones searched the area they had left behind.
• Yuko explained that one Deoxys had been preserved inside a meteorite, and Gary sensed its life force in the Crystal Body.

• Gary explained that Rayquaza had attacked the two extraterrestrial Deoxys and that the Purple Core Deoxys had come to LaRousse City searching for its companion.
• Yuko explained that the Purple Core Deoxys had captured people and Pokémon because their Thunder Waves obstructed its vision, and Gary proposed reviving the other Deoxys to end the crisis.
• Yuko warned that the backup power supply could not revive Deoxys, and Hitomi and Arlon both said they had a way.

Gary, Ash, and their allies split up to rescue LaRousse City’s trapped residents and power the equipment needed to revive the Green Core Deoxys. After it revived, the Green Core Deoxys carried Gary, Ash, Shota, and their Pokémon toward the city outskirts, where its Purple Core companion was battling Rayquaza.

• Hitomi and Arlon proposed rescuing the trapped people and Pokémon while using Wind Power Generation to supply energy for Deoxys’s revival.
• Gary’s group encountered the Purple Core Deoxys, and Gary stayed behind with Arcanine so Ash, Arlon, Hitomi, and Shota could continue the rescue.
• Rayquaza broke through the Purple Core Deoxys’s barrier, and the two Legendary Pokémon began fighting across LaRousse City.
• Gary returned to the research institute and learned that the rescued people and Pokémon had gone to the Wind Power Station to help provide electricity.
• Yuko used the available power to revive the Green Core Deoxys, which then carried Gary, Ash, Shota, and their Pokémon through the roof and toward the outskirts of the city.

Gary, Ash, and Shota persuaded Green Core Deoxys and Rayquaza to stop their destructive battle in LaRousse City. The Deoxys returned to their home world, and Rayquaza gave Gary its Dragon Scale before the group left, with Shota able to interact with Pokémon again.

• Gary, Ash, and Shota asked Green Core Deoxys to stop Rayquaza and Purple Core Deoxys from destroying more of LaRousse City.

• Rayquaza thanked Gary, gave him a Dragon Scale that could summon its help, and flew away.
• Gary, Ash, and the others left LaRousse City, and Shota was able to interact with Pokémon again.

• Gary, May, and Hilda boarded Drake's ship.

• Gary used Electivire’s Iron Tail and Thunderbolt to pressure Drake’s Shelgon, while Drake boosted Shelgon’s defense and countered with Dragon Pulse.

• Gary sent out Pupitar and Lairon and ordered them to attack with Rock Throw and Rock Slide.
• Solrock and Lunatone dodged among the artificial planets, but Pupitar and Lairon destroyed nearly all of them, angering Tate and Liza.

Gary battled Tate and Liza as their inability to coordinate caused their attacks to fail, while Gary and his Pokémon worked together to defeat their team. The battle ended with both Lunatone and Solrock unable to continue fighting.

• Tate ordered Solrock to attack, but Gary's Pupitar blocked its Flamethrower and Lairon struck Solrock with Stone Edge.

• Tate and Liza showed Gary, Rosa, and Hilda the space center’s astronaut training machines and led them toward the room holding a meteorite.

• Gary, Rosa, and Hilda said goodbye to Tate and Liza and left Mossdeep City for the docks.

• Rosa and Hilda urged Gary to help, and he agreed, learning that Lance had told Steven about Groudon and Kyogre.
• Gary, Rosa, and Hilda changed course and flew from Mossdeep City toward the location Steven provided.

Gary, Rosa, and Hilda rushed to the island after Kyogre awakened and unleashed torrential rain. They joined Steven and Lance as Archie, controlled by the Red Orb, threatened to sink the island and the world, leaving everyone to face the crisis as someone called out to Gary and Steven.

• Rosa noticed the weather turn from sunny to dark and rainy, and Gary said Kyogre must have awakened.
• Archie used the Red Orb to command Kyogre, threatened to drown the world, and ignored Lance's warning that the orb was controlling him.

• Lance told the newcomers how the crisis had unfolded, and a shout to Gary and Steven drew everyone's attention.

Gary and the others found Ash and learned Pikachu had been possessed by the Blue Orb, while Steven Stone and Lance set out to stop Archie and recover the Red Orb. Groudon awakened on the island, and Kyogre turned its attention toward it, sending a towering wave toward Gary’s group as the two legendary Pokémon prepared to clash.

• May, Brock, and Max joined Gary, Rosa, Hilda, Steven Stone, and Lance, and Lance rescued Ash from Team Magma’s helicopter.

• Kyogre sent a massive wave toward Gary and the others on the island.

As Groudon and Kyogre’s battle unleashed devastating weather across Hoenn, Gary used a Green Scale and his Viridian Power to call for Rayquaza’s help. A dragon’s roar answered from the sky, and Rayquaza appeared before the gathered group.

Gary summoned Rayquaza to stop Groudon and Kyogre, then used the Dragon Ascent Scroll to help it Mega Evolve and reach the strength of a Tier 1 Deity. Mega Rayquaza began fighting the pair, but Groudon joined Kyogre’s attack as Gary called out to Rayquaza.

• Lance and Steven Stone recognized Rayquaza when it arrived, and Gary asked it to stop Groudon and Kyogre’s renewed battle.
• Rayquaza admitted it was too weak to face the two Tier 1 Deities, so Gary showed it the Dragon Ascent Scroll and Rayquaza agreed to fight.

• Gary directed Rayquaza to dodge Groudon and Kyogre’s attacks, then strike Kyogre with Dragon Tail and Groudon with Draco Meteor, sending both into the sea.
