From Bulbapedia, the community-driven Pokémon encyclopedia.
A glitch Pokémon is a Pokémon that only exists in the games due to a programming oversight, when the game attempts to draw up data for an invalid Pokémon.
Some glitch Pokémon have characteristics derived from the game's default error handling capabilities for an invalid Pokémon, such as the name "Missingno." or "??????????". Another example of this is learn-set data for an egg Generation IV, where it learns Splash as a starting move, likely to prevent the game freezing from an invalid move from being used.
In Generation I, some glitch Pokémon may freeze the game if sent out on the opponent's side, depending on their Pokédex number and the version used, and glitch Pokémon with index numbers greater than 199 will always bring up equivalent glitch Trainers if encountered directly in the wild. These glitch Pokémon cannot be obtained via a wild battle, and must be obtained using a different glitch to the Ditto glitch or old man glitch, such as evolution from another glitch Pokémon, trading an equivalent index number glitch Pokémon to another version, or the Johto guard glitch.
Additionally, catching certain obtainable glitch Pokémon in Generation I may cause endless Pokédex data to appear. To avoid this, the player must have activated a specific flag, if this is a hybrid glitch Pokémon, the flag is activated by either seeing a specific Pokémon or owning a specific Pokémon.

Please feel free to edit this section to add missing information and complete it.
Reason: Index numbers 000, 152-250, 255 and the 39 Missingno. are currently confirmed obtainable. Needs Johto guard glitch Pokémon. In Red and Green, 251-254 should be obtainable via the Fossil conversion glitch (a select button glitch), but I don't know if Bulbapedia considers that notable? --Chickasaurus 18:48, 18 May 2011 (UTC)

Trivia
- There are 39 Missingno. with identifiers in between real Pokémon, which would add up to 190 Pokémon.
- Interestingly, recent words from Shigeki Morimoto state that there were once 190 Pokémon planned for development in Pokémon Red and Green.[1]
- This may or may not be a coincidence because the error handler MISSINGNO. is used for blank, or formatted Pokémon data. Many of its characteristics are either a translated 0 value (e.g. default Nidoran♂ cry with pitch 0), or blank data rolled over to the next logical values (e.g. base stats denoting the rosters of several burglars.)
