In-Depth Analysis
Koffing's 340 base stat total marks it as a balanced Pokémon with a flexible stat spread. Defense (95) carries most matchups, but a low Speed stat of 35 means careful positioning matters.
Defensively, the Poison combination gives Koffing 5 resistances and 2 weaknesses to plan around. Notably, it carries no 4× weaknesses, which makes it harder to punish. Offensively it pressures 2 types with super-effective STAB coverage.
With a catch rate of 190, Koffing is comparatively easy to catch in the wild. It levels on the Medium experience curve. Defeating it grants Defense +1 EVs, which is worth remembering when EV-training your own team.
