Stats & Training
Gastrodon's spread is anchored by HP, with balanced defenses backing it up. Speed is the clear weak point. Worth 2 HP EVs per KO, and the medium-fast 1M XP curve keeps leveling painless.
It has a pliable body without any bones. If any part of its body is torn off, it grows right back.
It apparently had a huge shell for protection in ancient times. It lives in shallow tidal pools.
Gastrodon Weakness
Gastrodon's Water/Ground typing leaves it vulnerable to Grass. Grass hits land at 4x, so they're the biggest threat. It shrugs off Electric-type attacks completely. It resists 4 types, giving it decent defensive coverage. Storm Drain grants an additional Water immunity, reshaping the matchup chart. With 111 HP and balanced defenses, Gastrodon can afford to eat a neutral hit or two.
| Damage | Types |
|---|---|
| 4x (Critical) | Grass |
| 0.5x (Resist) | Fire, Poison, Rock, Steel |
| 0x (Immune) | Electric |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

Gastrodon Guide
In Diamond & Pearl, Don't let Gastrodon's 475 base stat total fool you. Storm Drain is what makes it tick. It punches way above its weight class. We rate it C-Tier as a trick room. Recover with Leftovers is the standard set.
In Diamond & Pearl, watch for Roserade (Grass) when using Gastrodon. They all hit it super-effectively with STAB. Roserade is the most dangerous since Grass moves deal 4x damage. Only 1 weakness means fewer dedicated counters to worry about. At base 39 Speed, Gastrodon won't outrun any of these threats so switching to a resist is usually the safer play.
In Diamond & Pearl, Run Storm Drain on Gastrodon. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Gastrodon also gets Sticky Hold and Sand Force, but they don't compare.
In Diamond & Pearl, Gastrodon fills the trick room role. It's a mixed attacker with base 83 Attack and 92 Sp. Atk. Base 39 Speed is low. Priority moves or Trick Room are the way to go. And it's enough bulk to take a hit or two.
For Diamond & Pearl, Gastrodon has answers, but so do you. Super-effective STAB from faster Pokemon is the simplest answer. Grass-type attackers hit hardest.
