MissingNo., also known as MissingNO, is the name of a glitch Pokémon that is short for "Missing Number". MissingNo. Pokémon are used as error handlers by game developer Game Freak; they appear when the game tries to access data for a Pokémon species that does not exist.

First documented by Nintendo in the May 1999 issue of Nintendo Power, encountering MissingNo. results in messed up graphics and item duplication of the player's sixth item in their inventory.
