Provenance

Where it came from

Gastrodon (29/114) was released as part of the Pokémon Trading Card Game expansion Steam Siege, which debuted internationally in August 2016. The set focuses on the duality between Shiny Mega Gardevoir-EX and Volcanion, highlighting the unique mechanics of dual-type Pokémon. Within this context, Gastrodon serves as a Water-type representative, reflecting its origin in the Sinnoh region games where it famously possesses two distinct forms based on its habitat.

The card features an illustration by Mitsuhiro Arita, one of the most prolific and recognized artists in the history of the Pokémon TCG. Arita’s approach typically emphasizes the creature's natural environment and anatomical texture, and his depiction of Gastrodon captures its slug-like characteristics with a soft, naturalistic aesthetic. The card was received as a standard rare inclusion in the set, serving as a functional piece for collectors aiming to complete the Steam Siege expansion.
