Additional Notes and Trivia

  • Koffing's English name was originally going to be Ny, referring to New York's polluted air.
  • The skull-and-crossbones pattern was placed above Koffing's eyes in the US Red and Blue versions as well as the Japanese Blue version, but was moved below his mouth from Yellow version onwards. It's unknown whether this was just a sprite error as the original Japanese Red and Green versions showed the pattern below his mouth also.
  • Koffing is Ryan Davis & Jeff Gerstmann's favourite Pokémon.
