Lore

Why it matters

As a psychic-type card, this Grimer represents a notable shift in how the creature is classified compared to its more traditional appearances. Despite its common rarity, collectors prize these early instances of type-shifting for the unique perspective they offer on the evolving mechanics of the game.

Provenance

Where it came from

The Grimer card from the HS—Undaunted expansion was released in 2010 as part of the HeartGold & SoulSilver series of the Pokémon Trading Card Game. This set was notable for its emphasis on the Johto region, featuring mechanics that highlighted the synergy between Pokémon and their trainers. Grimer, a Generation I Poison-type Pokémon, was rendered in a style consistent with the game’s aesthetic, designed to emphasize its sludge-like composition and unsettling nature.

The artwork for this particular card was illustrated by Mitsuhiro Arita, one of the most prolific and recognized artists in the history of the Pokémon TCG. Arita’s approach typically balances the creature's canonical lore with a textured, painterly style that brings a sense of depth to otherwise common cards. Within the context of the Undaunted set, this common-rarity card functioned as a staple for players building decks around the game's evolving mechanics, and it remains a point of interest for collectors focusing on Arita's extensive body of work.
