Gastrodon is first introduced in Generation IV or the original Pokemon Diamond and Pearl, Gastrodon evolves from Shellos starting at level 30. And in Pokemon Brilliant Diamond and Shining Pearl, you can also find Gastrodon roaming about in Fuego Ironworks, Route 218, Route 224, Route 230, or Pokemon Hideaways, specifically in the Fountainspring Cave. The East Sea variant is colored blue while the West Sea is pink. Although it doesn’t look particularly strong, Gastrodon is one of the few Pokemon which has a rare Water/Ground dual-typing, making its weaknesses somewhat elusive. In case you forgot or are a newcomer to the series, read below for more details on Gastrodon’s weaknesses in Pokemon Brilliant Diamond and Shining Pearl.
Gastrodon Stats
Gastrodon is a Water/Ground-type Pokemon. With that in mind, its only weakness is Grass-type attacks since Water and Ground dual-typing Pokemon are only (extremely) susceptible to Grass attacks. Meanwhile, Gastrodon is completely invulnerable to Electric-type attacks, thanks to its second Ground-typing. Yes, this means all Ground-type Pokemon are also immune against Electric-type attacks. It also takes reduced damage from Fire, Poison, Rock, and Steel moves.
It’s somewhat important to remember that Gastrodon has lower Defense stats compared to its Special Defense. This suggests that you should use Physical Grass attacks such as Bullet Seed, Leaf Blade, or Seed Bomb to maximize your damage output. For convenience, below is the table that lists Gastrodon’s type weaknesses and strengths in Pokemon Brilliant Diamond and Shining Pearl.
| 4x Damage | 0.5x Damage | 0 Damage |
| Grass | Fire | Thunder |
| Poison | Water | |
| Rock | ||
| Steel |
