Gastrodon (トリトドン) is the 61st Pokémon in the Sinnoh Pokédex. It is a Water/Ground Type, and is known as the Sea Slug Pokémon.

Gastrodon can use one of two Abilities: Sticky Hold, which prevents opponents from taking its Held Item; or Storm Drain, which draws Water-Type moves to it, nullifying any damage that would have been done to it and increasing its Special Attack by one stage. A third Ability is available to Gastrodon from the Dream World, the Sand Force Ability. This Ability grants a 33% Increase to Ground, Rock and Steel-Type moves during a Sandstorm.

Shellos can evolve into Gastrodon at Level 30.

Gastrodon is in the Egg Groups Water 1 and Amorphous, and its Egg takes approximately 5,120 Steps to hatch. It takes Gastrodon One Million Experience Points to reach Level 100.

[edit] Game Information

[edit] Original Games

Gastrodon can be found at Routes 213, 218, 224 and Fuego Ironworks in Diamond, Pearl and Platinum. Gastrodon also appears at Routes 221, 222 and 230 in Diamond and Pearl, and at Route 205, Route 212, Pastoria City, Canalave City and Valley Windworks in Platinum. The only way to obtain a Gastrodon in Heart Gold, Soul Silver, Black 2 and White 2 is to evolve a Shellos.

[edit] Spin-Off Games

West Sea Gastrodon can be found at Brine Cave B1-B9 & DPB1, while East Sea Gastrodon appear at Craggy Coast B6-B9 and Small Path B1-B5 in Explorers of Time, Explorers of Darkness and Explorers of Sky. Gastrodon appears in all three versions of Mystery Dungeon 3, appearing at Secret Archipelago, Legendary Volcanic Island, Secret Highland, Legendary Wetland, Secret Rockmountain and Legendary Mountains. The Secret-named areas feature Gastrodon on floors 18-29, while the Legendary-named areas feature Gastrodon on floors 1-25. In both areas both forms of Gastrodon appear on different floors.

Gastrodon can be found at Marine Cave and Volcano Cave in Pokémon Ranger: Shadows of Almia. In Pokémon Ranger: Guardian Signs, Gastrodon can be found at the Hot Springs on Faldera Volcano in the Present, but Gastrodon doesn't appear in the Past Missions.

Gastrodon appears at Desolated Ruins Beach 3-1 and Sunny Seashore Beach 4-3 in Pokémon Rumble Blast.

[edit] Trading Card Game

Both forms of Gastrodon are featured in the Trading Card Game twice each, with both forms being listed as Rare Cards in the Secret Wonders and Rising Rivals sets.

[edit] Anime/Manga Information

[edit] Anime

Gastrodon has only appeared with a Trainer so far in the Anime. Cynthia would use a West Sea Gastrodon in the episodes Double Team Turnover! and Aiding the Enemy. Zoey would debut a West Sea Gastrodon of her own during the Sinnoh Festival, which had evolved from her Shellos. Paul used an East Sea Gastrodon in his Sinnoh League Battle against Ash in the first part of the battle, which occurred in the episode Familiarity Breeds Strategy!. It would give Ash's Staraptor all it could handle, but Ash made the substitution to Buizel, who managed to defeat Gastrodon.

[edit] Movies

Gastrodon has yet to appear in any of the films as of writing.

[edit] Manga

Gastrodon's Manga Information is unknown as of writing.

[edit] Pokémon Information

[edit] Competitive Battling

Gastrodon found itself in the UU, or Under-Utilized Tier of Competitive Battling in Generation IV, but made the jump to the Over-Utilized and Uber Tiers of Competitive Battling in Generation V. Its high HP and good Special Defense give it staying power, and Recover allows it to survive even longer. Storm Drain also allows it to completely shut down Kyogre in the Uber Tier, but regardless where it is used, Grass-Type moves-especially from Pokémon that are faster than Gastrodon-are its biggest problem, which can easily bring it down.
