One hundred years prior to the events of the movie, a Hoopa appeared in Dahara City and often battled other Pokémon summoned through its rings and defeated them in order to showcase its strength to the people in town. As it soon became more arrogant, it soon summoned Legendary Pokémon to showdown with to further showcase its strength and powers. At first, Kyogre was summoned along with Groudon, and engaged in a three-way showdown between it, Hoopa, and Groudon. It was soon driven into Hoopa's rings and defeated along with Groudon.
When Hoopa's rage over having its power sealed for so long manifested as a shadow, the shadow Hoopa summoned another Kyogre, in its Primal form, along with Primal Groudon, Dialga, Palkia, Giratina, and Kyurem and was controlled by Hoopa to fight Mega Rayquaza, Mega Latias, and Mega Latios. It was psychically controlled to fly around town, and frequently attacked the three with Origin Pulse while quickly flying around, causing major destruction in the process. Later, when Hoopa's power was tamed, Kyogre was freed from the Shadow's control. However, due to the violent clash between Legendary Pokémon, time and space were warped and slowly began to consume Dahara City. While Hoopa helped the townspeople escape, Kyogre joined the other legendaries in attacking the space-time distortion while everyone escaped. Once all had been saved, Kyogre returned to its home along with Groudon.
