Groudon is a companion Pokémon, which merges with Gary after it is placed under mind control. 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.Along with Kyogre and Rayquaza, Groudon is a part of the weather trio 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. Slow, stoic, and heavy (2094 pounds), this super-heavyweight created the land, according to Hoenn legend. It sleeps underground in large magma chambers, and causes volcanoes to erupt when it awakens. It is said to appear before those with shining silver spirits. If it encounters its rival Kyogre, Groudon will engage Kyogre in a fight to the death. Groudon sleeps miles below the ground (occasionally in deep, hot magma pockets), and is therefore nearly impossible to find in the wild without awakening it.
