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.
Its whole body is sticky with mucus. In the past, this form of Gastrodon was by far the more numerous one.
It appears on beaches where the waters are shallow. Once it catches prey, it will slowly melt them with its mucus before slurping them up.
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 Scarlet & Violet, 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 trick room. Recover with Rocky Helmet is the standard set.
In Scarlet & Violet, 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 Scarlet & Violet, 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 Scarlet & Violet, Gastrodon fills the trick room role. It's leaning toward the special side (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 Scarlet & Violet, run Recover, Earthpower, Ice Beam, and Spikes on Gastrodon. Recover is the most common pick at 21% usage. This set covers the trick room role with a mix of damage and utility.
