Koffing is a two-button character that uses the (A) and (B) buttons to fight. It has many similarities to Mighty Akuma's Evil Gastly, in that it can't jump, block, or crouch. It also has a similarity to the Charmander made by an unknown creator, as well as Omega Clarens' Chikorita, in that it can't get up if it suffers a Hard Knockdown.
The ReadMe file gets a few things wrong, such as stating that its thick fog and smoke screen are activated by pressing +(A) and +(A) respectively, when they are actually activated by pressing (B) and (A)+(B).
Though the creator promised that he/she would increase the quality of the character and that he/she would make more Pokémon characters, Koffing hasn't been updated since nor did Moyashi ever follow up on his/her Pokémon idea.
Hovering the mouse cursor over the Command Input icons will display text that refers to the inputs set in M.U.G.E.N's Key Config.
Icons encased in square brackets [ ] require the respective button(s) to be held down. Hovering the mouse cursor over the gap displays the hold duration if applicable.
