Koffing is one of the thirteen Pokémon that can come out of a Poké Ball in this game. It uses Poison Gas as its attack. Koffing releases gas from the pores on its body. Any character, other than the summoner, who touches the gas takes damage, and if he/she is very close to Koffing, he/she becomes trapped until Koffing disappears.
Koffing's evolved form, Weezing, replaces it as the same type of attacking Pokémon in Super Smash Bros. Melee. Neither Koffing nor Weezing appear in Super Smash Bros. Brawl.
This Poison-type Pokémon's balloon-like body is filled with toxic gases. In Smash Run, it floats over to fighters and expels gas at regular intervals. If the gas touches you, the stats you've worked so hard to build up drop! Attack while it's deflated to take it down safely, and them help yourself to the many, many items it leaves behind.
