Kyogre

Kyogre (Japanese: カイオーガ Kyogre) is a Water-type Legendary Pokémon introduced in Generation III.

While it is not known to evolve into or from any other Pokémon, it can undergo Primal Reversion and become Primal Kyogre if it holds the Blue Orb.

Kyogre possesses the ability to expand the oceans. In ancient times, it came into conflict with Groudon, a Pokémon with the ability to expand continents. In Pokémon Sapphire, Emerald, and Alpha Sapphire, Kyogre is sought after by Team Aqua as part of their plot to create more habitats for aquatic Pokémon by raising the sea level.

Kyogre is the game mascot of Pokémon Sapphire and its remake, Pokémon Alpha Sapphire, with Kyogre appearing on the box art of Sapphire and Primal Kyogre appearing on the box art of Alpha Sapphire.

Along with Groudon and Rayquaza, Kyogre is a part of the weather trio.
