Versatile Mage: Rayquaza Captures the Black Dragon Emperor at the Beginning

I just went to Italy to find my mother, but unexpectedly awakened independently at the age of 14, summoned the dead, and was accompanied by a magic tool [Poké Ball]! There are no restrictions on summoning skills or realms. You can summon any Pokémon you want! Yin Hong was a little confused, and then decided to go to the Tyrant Mountains to do something big! But when he arrived at the Tyrant Mountains, with a shake of his hand, he summoned the enemies Groudon and Kyogre! Groudon and Kyogre started fighting as soon as they came out, and the Black Dragon Emperor, who was already severely injured, was even more confused. Seeing that the Tyrant Mountain Range had been split in half, Yin Hong hurriedly summoned Sky Overlord Rayquaza again. Rayquaza was too yin, and it had been stacking dragon dance as soon as it was summoned. By the time it flew on top of Groudon and Kyogre, it had already stacked six layers. With the finishing touch, Groudon and Kyogre ran away, and even the Black Dragon Emperor was knocked unconscious. While there was no one around, Yin Hong quietly contracted the Black Dragon Emperor and ran away. Unexpectedly, it was sensed that the power of disaster was still there, and he was wanted by the Holy City. Yin Hong said, I am just incorporating an emperor-level combat force into mankind. Am I wrong?
