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.
Groudon is a massive, bipedal, dinosaur-like Pokémon covered in red, segmented plates of thick skin that act as armor. It has a gray underside and large white spikes that run along the sides of its head, body, and tail. Groudon has four claws on each hand, four dozer-like blades on the end of its large tail, and three claws on each foot with gray markings under its feet. It also has blue stripes inside the seams of its armor plating which can only be seen when Groudon is glowing with power.
As Primal Groudon, its appearance is similar to Groudon, but larger in size. Its skin color changes from dark red to deep crimson with its underside, spikes, and teeth turning black. The blades on its tail are more separated from one another. The Ω symbol is now shown on its arms. Its eyes, the inside of its mouth, and the now-enlarged openings between its armor plating glow bright yellow, and its irises are now red. The energy that fills Primal Groudon pours forth as magma, and it burns with such an extreme temperature that its body is always shimmering with the haze of its heat. In the anime, Primal Groudon is said to create new land with every step it takes.
Groudon is an immensely powerful Pokémon, having the ability to summon intense droughts and cause volcanic eruptions. The droughts it can cause allow it to evaporate water, while the volcanic eruptions it can summon enable it to create land. It sleeps underground in large magma chambers. If it encounters its rival, Kyogre, they will engage in a cataclysmic battle. Groudon is the only known Pokémon capable of learning the move Precipice Blades.
In the beginning of Hoopa and the Clash of Ages, a Groudon was summoned by Hoopa to defeat it in the past. A Primal Groudon was later one of six Legendary Pokémon summoned and hypnotized by the shadow Hoopa Unbound as its reinforcements. It and its teammates engaged in a battle against the Latios, Latias, and ShinyRayquaza summoned to protect the real Hoopa in Dahara City. Eventually, after the shadow Hoopa was sealed in a Prison Bottle, the hypnosis on Primal Groudon and the other Legendary Pokémon was lifted, and Primal Groudon departed for its home.
Groudon debuted in the opening sequence of Jirachi: Wish Maker, where it was seen rising out of the lava in a volcanic area while being monitored by Team Magma.
In The Vision, Courtney had a vision in which a Primal Groudon destroyed a chain of islands before attacking Maxie and Tabitha. While she was puzzled by the vision's meaning, this ultimately did not deter her from carrying on Team Magma's plans.
A Groudon briefly appeared as a silhouette in GOTCHA!.
Groudon's first appearance was in Assaulted by Pelipper I. Awakening Groudon was the main mission of Team Magma, so they could expand the land. Groudon was finally awakened when Team Magma and Aqua formed a temporary truce to be able to go underwater. Wallace, Brawly, and Roxanne tried to stop the Pokémon's advance but failed due to the interventions of Blaise, Courtney, and Tabitha. Eventually, it reaches its destination: Sootopolis City, to battle Kyogre, which it did for days on end until Ruby, with the aid of a reformed Courtney and his own, Rayquaza-controlling father, managed to quell it. Afterwards, it cut its ties with Kyogre and went to resume its slumber at the bottom of Mt. Chimney. It is shown afterwards that this restored the volcanic activities that Team Aqua had earlier annulled.
Groudon is obtainable as a Poké Ball Pokémon. It uses Overheat to immolate itself in a fiery aura, causing anyone (except the summoner) who comes into contact with it to be knocked back and receive damage, similar to the attack of Moltres, though it lasts longer. Due to its tremendous size, it takes up a lot of the stage, making its attack almost inescapable. However, Groudon's attack is significantly weaker than Moltres', as it deals less knockback and damage; making it very hard to directly KO an opponent until they reach a very high damage percentage.
"A Continent Pokémon. In ancient times, it brought down droughts to save people who had suffered from floods. It is normally found in the profound depths of the earth, where it slumbers in magma. With a mighty roar, it uses Earthquake to mow down enemies. In battle, it summons sunlight to bathe the area. It once had an epic battle with Kyogre."
NA: Groudon is called the Continent Pokémon, and that's not just because it lives on them. Legend has it that Groudon actually created the continents. It has a rivalry with Kyogre, said to have created the oceans, and they apparently had an epic battle long ago. Perhaps our world was born from this great battle between land and sea.
PAL: Groudon is called the Continent Pokémon, and that's not just because it lives on them. Legend has it that Groudon actually created the continents. It has a rivalry with Kyogre, said to have created the oceans, and they apparently had an epic battle long ago. Perhaps it was this battle of land and sea that created the world as we know it.
Both Groudon and Primal Groudon appear as Spirits.
Pokémon Pinball: Ruby & Sapphire: Groudon is the focus of the second Bonus Field on the Ruby Field. Groudon will throw rocks down from the ceiling to add obstacles to the field and create an eruption to surround itself in pillars of fire. The rocks take three hits to break while the fire pillars take four hits to break. During this time, Groudon will also throw fireballs at the Poké Ball to stall it further. The eruption does break any rocks still on the field. Groudon must be hit 15 times in three minutes to win. After beating the round twice, Groudon will be captured.
In its early design, Groudon's eyes were shaped differently, with the positioning of the spikes on its body being slightly different. Its head details became much more elongated in the final version, and the super-ancient Pokémon's signature body patterns are not present.
Groudon may be modeled after the Earth's land and volcanoes and may be a personification of the land. Its conflict with Kyogre is similar to that of Behemoth and Leviathan of Hebrew legend, who at the end of time would start a battle that would kill them both.
Groudon may be a combination of ground and don (Spanish for lord). It may also incorporate -don (common suffix in names of dinosaurs), which is derived from ὀδών odṓn (Ancient Greek for tooth). It may also involve 土 do (ground) or ドン don (onomatopoeia for a very loud crashing noise).
