Koffing

Koffing is a Poison-type Pokémon introduced in Generation I, known for its spherical body filled with noxious gases. This Pokémon is often found in urban areas, particularly around garbage dumps and polluted environments, where it feeds on the toxic fumes and decaying matter. Koffing evolves into Weezing starting at level 35. In the Pokémon anime, Koffing is famously one of James's original Pokémon in Team Rocket, often seen alongside Jessie's Ekans (later Arbok), contributing to their recurring comedic villainy. Its simple yet distinctive design, featuring a skull and crossbones-like symbol on its body, makes it instantly recognizable. Koffing's ability to float and its constant emission of gas are central to its character, highlighting its toxic nature. As a pure Poison type, it is weak to Ground and Psychic-type moves, resistant to Fighting, Poison, Bug, and Grass, and takes neutral damage from other types. Its role in the games often involves being an early-game Poison-type option, and its evolution, Weezing, sometimes sees competitive play due to its abilities and bulk.
