Plan this partner in PokéBonk

This analysis describes the Koffing League partner and its evolution line, not necessarily the current form alone.

Koffing can glide and climb while its nearby poison cloud adds steady local pressure. Weezing's cloud-and-detonation Ultimate provides a much larger clear later.

Trade-off: A short-range Smog opening and cloud positioning ask more effort before that payoff arrives.

Passive: Toxic Cloud

Ultimate progression: Explosive Cloud / Big Blast

Curated kit: Smog (Lv. 1) · Clear Smog (Lv. 2) · Self-Destruct (Lv. 4) · Explosion (Lv. 7)

Later moves become eligible offers; they are not automatically equipped.
