GrimerBrilliant Stars #84 Pokémon Card

Grimer is a Poison-type Pokémon first introduced in Generation I, making its debut in the Kanto region. Known as the Sludge Pokémon, Grimer is literally a living pile of toxic sludge, formed from the waste products of factories. Its natural habitat is typically polluted areas like sewers, industrial zones, and contaminated waterways, where it thrives on garbage and toxic waste. Grimer's behavior is often depicted as mischievous and playful, despite its dangerous composition; it enjoys lurking in murky waters and surprising unsuspecting individuals. Its diet consists entirely of industrial waste and dirty sludge, which is essential for its survival and growth. Grimer evolves into Muk, another formidable Poison-type, at level 38. In the games, it's a common encounter in polluted areas, and in the anime, Grimer often appears as a troublesome but sometimes endearing antagonist, notably belonging to Team Rocket's James at one point. Its existence serves as a poignant commentary on environmental pollution, making it a culturally significant Pokémon that highlights ecological concerns within the franchise. Type matchups see Grimer weak to Ground and Psychic types, resistant to Fighting, Poison, Bug, Grass, and Fairy types, and it takes neutral damage from other types, reflecting its toxic nature.
