Kyogre
The Sea Basin Pokémon
Type: Water
Official Registration #: 382
Entry: The ancient god of the sea, according to Hoennian legend. According to ancient Hoennian texts, Kyogre shaped the oceans by controlling the very waves themselves and bringing down torrential downpours. Interestingly, unlike many other myths concerning the creation of a world, Kyogre had a motivation behind it: namely to establish the dominance of aquatic pokémon in their fight against Groudon and its land-based followers. This means that the ocean itself exists thanks to a petty quarrel that happened eons ago, and because of this, the author is not sure whether to be impressed or to assume this explains quite a bit about the human race if this is how they say the world was formed.
Groudon
The Continent Pokémon
Type: Ground
Official Registration #: 383
Entry: The ancient god of the land, according to Hoennian legend. According to ancient Hoennian texts, Groudon had the power to raise landmasses and control magma, which one would assume were the powers it used in its quarrel against Kyogre to create the land. But no. No, reader, the power it used in its fight against Kyogre, the almighty ability that cut continents through Kyogre’s very oceans, was the ability to dispel clouds and make it especially sunny.
