Koffing

#113 in the Omega Ruby and Alpha Sapphire Pokédex • Poison Gas Pokémon

Omega Ruby

If Koffing becomes agitated, it raises the toxicity of its internal gases and jets them out from all over its body. This Pokémon may also overinflate its round body, then explode.

Alpha Sapphire

Koffing embodies toxic substances. It mixes the toxins with raw garbage to set off a chemical reaction that results in a terribly powerful poison gas. The higher the temperature, the more gas is concocted by this Pokémon.
