Koffing (Japanese: ドガース Dogars) is a Poison-type Pokémon. It evolves into Weezing starting at level 35.
Koffing is a round, limbless purple Pokémon filled to the brim with toxic gases. Several crater-like protrusions on this Pokémon's thin body give it the resemblance of a meteorite or a naval mine. Although Koffing is usually seen with only two small fangs in its mouth, it has a full set of flat teeth as seen in Rocking the Virbank Gym! Part 1. Koffing has a skull and crossbones below its blissful face. Koffing has been considered to be related to Grimer, who is also a purple Poison-type Pokémon that associates with pollutants. Koffing may also be related to Drifloon, who is also a floating, round, purple, "X"-bearing Pokémon with a tendency to explode.
