Arc 27The Sinjoh Ruins
Roy and Cynthia uncovered a Space-Time Rift at the Ruins of Alph and entered the buried Sinjoh Ruins, where Roy met Arceus and helped transform Mimikyu into a Pokémon. They escaped the ruins but became stranded together in a vast snowfield.
- Roy arrived at the Ruins of Alph with Cynthia and Professor Carolina, who traced the murals to Ancient Sinnoh immigrants and the lost Sinjoh Ruins.
- Roy placed Golurk on the altar, and the runes and Unown opened a Space-Time Rift that led toward Johto’s northern snowfields.
- Roy and Cynthia crossed the rift and found themselves trapped among towering snow walls, then discovered the Sinjoh Ruins and a gigantic statue of Arceus.
- Arceus emerged in a Ghost-type avatar, confronted Roy about his connection to Giratina, and summoned Giratina from the Distortion World.
- Roy strengthened his Ghost Power, caught Arceus in a Luxury Ball, and empowered him, while Arceus tore open rifts, repaired the Distortion World, and warned Giratina to protect Roy.
- Roy asked Arceus to help Mimikyu, and Arceus used the Ghost Slate and her Reaper Cloth to transform her into a Pokémon.
- Roy and Cynthia left the vanished Sinjoh Ruins through a gap in the snow wall, but found themselves stranded on an unfamiliar snowfield without working navigation devices.
- After Dragapult suffered frostbite and Cynthia sprained her ankle, Roy treated them and carried Cynthia as they searched for shelter and realized they had walked in a circle.
