Groudon

Groudon (Japanese: グラードン Groudon) is a Ground-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 Groudon if it holds the Red Orb.

Groudon possesses the ability to expand continents. In ancient times it came in conflict with Kyogre, a Pokémon with the ability to expand the oceans. In Pokémon Ruby, Emerald, and Omega Ruby, Groudon is sought after by Team Magma as a major part of their plot to create more habitats for land Pokémon by lowering the sea level. Groudon is the game mascot of Pokémon Ruby and its remake Pokémon Omega Ruby, with Groudon appearing on the box art of Ruby and Primal Groudon appearing on the box art of Omega Ruby.

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