Trivia

 * Weezing is much heavier than its pre-evolution, Koffing.
 * While two Koffing are said to fuse into Weezing, the anime and games simply have a single Koffing evolve into Weezing.
 * Weezing and its pre-evolution, Koffing, were originally going to have part -type Alolan Forms in Sun and Moon.
 * In Super Smash Bros., Weezing is one of the Pokémon that can be freed from Poké Balls. During this time, it uses the move Smog.

Origin
Weezing is based on air pollution and smog. Appeearance-wise it resembles a cloud or a naval mine. The tumor-like growth of its second head may be a reference to how pollution can cause cancer and mutations.

Etymology

 * The name "Weezing" is a homophone for "wheezing."
