Koffing, the Poison Gas Pokémon, is a spherical, purple creature known for its perpetually grinning face and the skull and crossbones symbol on its body, signifying its toxic nature. Introduced in Generation I, Koffing is a pure Poison-type Pokémon. It evolves into Weezing starting at level 35. Koffing is often found in polluted areas, abandoned factories, and cities, thriving on gases and garbage. Its diet consists of various toxic fumes and waste, which it absorbs and converts into its own poisonous gases. In the Pokémon anime, Koffing is famously associated with James of Team Rocket, evolving into Weezing and becoming a recurring antagonist alongside Jessie's Ekans/Arbok. Its role in the games often involves being an early-game Poison-type that can be quite useful against Grass and Fairy types. The skull and crossbones symbol on its body is a clear visual cue to its dangerous properties, making it instantly recognizable and a classic symbol of the Poison type. Its design perfectly encapsulates its toxic essence, making it a memorable Pokémon from the original 151.
