- The Sea Slug Pokemon. Gastrodon is #423 in the National Pokedex.
- First English card. Secret Wonders, November 1, 2007.

- Size. 0.9m (2ft 11in) and 29.9kg (66lb).

Prices are pricecharting.com's price guide value for an ungraded copy, read August 31, 2026. A guide value is computed across the sales PriceCharting tracks, which is a wider set of venues than any one marketplace. 2 cards of the 5,396 priced here are not listed by PriceCharting and keep their TCGplayer market price via TCGdex instead. Where a card comes as a normal, holo and reverse holo at different prices, the figure is the priciest of them. Prices move daily, so treat these as a ballpark. Search every card.

In the video games
What beats Gastrodon
Damage taken by a Water / Ground Pokemon, computed from the type chart. Everything not listed does normal damage.
- x4Grass, double weakness
- ½xFire, Poison, Rock and Steel
- 0xElectric, no effect at all
This is the video game chart, not the card game. The Pokemon TCG has eleven types and no type chart at all: Weakness and Resistance are printed on each individual card, and two cards of the same Pokemon can print different ones.
