Arc 5Giratina’s Challenge
Roy investigated Meteor Village with Steven, helped Dreepy say farewell to its dying Dragonite, and found valuable crystals and stones in Meteor Cave. After strengthening his Ghost Power and training his Pokémon, Roy was taken by Giratina to fight Deoxys, then returned to Agatha, who warned him to keep his abilities secret and questioned his unusual Pokéblocks.
- Roy helped Alai investigate a shadow stealing food in Meteor Village, and he and Steven followed Dreepy into Meteor Cave, where they met the elderly Dragonite it had been caring for.
- Dragonite passed its life energy to Dreepy and died, leaving Dreepy to travel with Roy, while Roy and Steven collected Mystery Crystals, Key Stones, and a Golurk Mega Stone from the cave.
- Roy returned to the Academy, improved his Ghost Power, and trained his Pokémon with new Technical Machines and custom Pokéblocks, helping Primeape master Fire Punch, Ice Punch, and more Rage Fists.
- Giratina pulled Roy and Primeape into the Distortion World, took them into outer space, and challenged Deoxys while Primeape repeatedly attacked Giratina to prove his strength.
- Roy lent Giratina his Ghost Power, and Giratina defeated Deoxys with a massive Shadow Ball as Rayquaza watched before retreating.
- Roy returned through a spatial rift and told Agatha about the battle, but she gave him a hundred lashes for neglecting training and warned him to keep his abilities secret.
- Agatha questioned Roy about his Ghost-type Pokémon and his Pokéblocks, then became curious about how he had safely used Fire Stone Shards and accepted his offer to demonstrate their preparation.
