The identities of the package Pokémon confirmed! Their names are Primal Groudon and Primal Kyogre! In the Hoenn region, it is believed that there are two great Legendary Pokémon: Groudon, who created the land, and Kyogre, who created the seas.
Their existence was told in a famous Hoenn legend:
Long, long ago, there appeared in Hoenn two Pokémon of fearsome power. These two became known, in later times, as Groudon and Kyogre. When Groudon howled, the earth swelled and the land grew wide. The sun blazed overhead, and all the world around the creature was enveloped in incandescent heat. When Kyogre roared, water poured forth and the seas spread outward. Dark clouds enshrouded the world, and the deluge fell upon all...
The legend told in Hoenn did not end there, however.
It was a primal age, early in the world’s history. The natural world was overflowing with energy. That energy granted Groudon and Kyogre an overwhelming power. Seeking ever more of that energy for themselves, the two clashed again and again, and their battles cast the people and Pokémon of Hoenn into great danger. Brimming with the overwhelming power granted to them by nature’s energy, their transformation was named "Primal Reversion" by later people. And the people called their tormentors Primal Groudon and Primal Kyogre...
The Pokémon that appear on these titles’ packaging are indeed Primal Groudon and Primal Kyogre, the Primal Reversion forms that have reclaimed their original power!
With an Ability that can control the weather and a high Attack and Defense, the powerful Pokémon Groudon obtains even greater power upon Primal Reversion. When Groudon undergoes Primal Reversion, it becomes Primal Groudon.
Through Primal Reversion, Groudon's powerful Attack grows even greater. It also gains the Fire type, raising the power of the Fire-type moves it can learn. And it appears that its Ability might get a boost! Look forward to more details about the power hidden within Primal Groudon!
