Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby.

Koffing Weakness

Ground and Psychic moves hit Koffing for super-effective damage. 5 resistances help offset the weaknesses. Levitate grants an additional Ground immunity, reshaping the matchup chart. Koffing's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
