|Debut:||Hoopa and the Clash of Ages|
Regigigas was among the many Legendary Pokémon summoned by Hoopa to Dahara City in ancient times in order for Hoopa to demonstrate its strength. Due to being drunk with its own power, Hoopa summoned Regigigas, Zekrom, and Reshiram all at the same time. The three attempted to defeat Hoopa but were themselves overcome, with Hoopa opening one of its rings beneath Regigigas' feet to send it back from whence it had come.
