|This article is a summary page for variations of certain glitches or phenomena such as Pokémon Cloning, glitch myths, beta elements, or a collective term for variations of glitch Pokémon which share similar names, sprites or other information.
This article is about Glitch Pokémon; the result for when the game attempts to manage values in the species byte for Pokémon, which were never defined by the game developers. For Pokémon with "glitch-like" properties, see glitchy.
The term Glitch Pokémon refers to Pokémon that were not intentionally coded into the game. These Pokémon arise as a result of the game trying to interpret some other type of data as a Pokémon and have identifiers that fall outside the normal range for Pokémon. They can be accessed by a glitch or by using a cheating device. Glitch Pokémon in the first two generations do not have true sprites and their "images" consist of scrambled data, with the exceptions of some hybrids, and have names that consist of glitch text. In the third generation, Decamarks all have the "unknown Pokémon" sprite seen in the Pokédex and are named ??????????, but not all Glitch Pokémon in Generation III are named "??????????" as other Pokémon may be named "?" or shortened versions of move names such as "RBOLT". Most Glitch Pokémon can learn glitch moves. A comprehensive list of Glitch Pokémon from the first and second generations can be located on the GlitchDex.
