Moyashi's version (1999)



Koffing is a Poison-type Pokémon from the Pokémon series. It evolves into Weezing, and appears at #109 in both the Kanto and National Pokédexes.

It stores gasses in its body, making it unstable and liable to explode at any moment. Its gasses have such a repugnant smell, that it can cause teary eyes. It has a thin, balloon like body, and it breathes poison when it's angry.

In M.U.G.E.N, Koffing has been made once by Moyashi. The character dates back to November 10th 1999, making it one of the oldest M.U.G.E.N creations, and it appears to use custom sprites.

Moyashi's version


This Koffing being released in the same year as M.U.G.E.N itself makes it the oldest known Pokémon character created for the engine, so the character's lack of moveset options and the inherently obvious bugs typically associated with DOS-era characters shouldn't come off as too much of a surprise. While Koffing is unable to perform basic actions like jumping, crouching or blocking, it has the benefit of permanent grab invulnerability.
