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.

Gastrodon Guide
In Brilliant Diamond & Shining 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 B-Tier as a support. Earthpower with Leftovers is the standard set.
In Brilliant Diamond & Shining 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 Brilliant Diamond & Shining 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 Brilliant Diamond & Shining Pearl, Gastrodon fills the support role. It's a special attacker with base 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.
In Brilliant Diamond & Shining Pearl, run Earthpower, Muddywater, Icywind, and Ice Beam on Gastrodon. Earthpower is the most common pick at 20% usage. This set covers the support role with a mix of damage and utility.
Game Availability
Gastrodon first appeared in Diamond & Pearl and has been available in 13 games across 7 generations. Obtainable through wild encounters in most titles where it appears.
