Stats & Training
Defense and Attack carry most of Koffing's stat budget. Speed's the obvious dump stat. Common in the wild and yields 1 Defense EV. Follows a medium-fast 1M XP curve.
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.
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.
Koffing Weakness
Ground and Psychic moves hit Koffing for super-effective damage. 4 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.

Moves
Without breeding, Koffing misses out on Destiny Bond and Pain Split. That's 6 egg moves adding depth that the base kit lacks. STAB comes from Sludge Bomb and Sludge, with Normal and Fire coverage and more rounding things out.
