Groudon (Japanese: グラードン Groudon) is a Ground-type legendary Pokémon. It is not known to evolve into or from any other Pokémon.
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 and Emerald Versions, 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 version mascot of Ruby, appearing on the boxart.
Groudon is a massive, bipedal, dinosaur-like creature with a gray underside and covered in red, segmented plates of thick skin which act as armor. There are also spikes that run along the sides of its head, body, and tail. It has four claws on each hand, four dozer-like blades on the end of its large tail, and three claws on each foot with grey coloration under its feet. Groudon also has blue marking stripes inside the seams of its armor plating which can only be seen when Groudon is glowing with power.
