Glitch Pokémon family

"Hybrid" redirects here, for other uses outside of Pokémon glitches see Wikipedia's disambiguation page.

The term Hybrid Glitch Pokémon refers to the numerous amount of glitch Pokémon which closely share some of the characteristics of a legitimate Pokémon, or sometimes a placeholder glitch Pokémon. Hybrids may share similar base stats of other Pokémon, have the same picture of that Pokémon, or on rare occassions share the same cry.

Hybrid glitch Pokémon have appeared in the Pokémon series ever since Generation I. For example, LM4 is a hybrid of Poliwrath and the variety of MISSINGNO. with a hexadecimal identifier of 1F is arguably a hybrid of 'M.

In Generation IV

Hybrid Glitch Pokémon in Generation IV or sometimes "DP hybrids" exist in Pokémon Diamond and Pearl and unlike the hybrid glitch Pokémon in Generation I these Pokémon are relatively in a sensible order with a hybrid of the glitch Pokémon with an index number of 0000 starting at a hexadecimal identifier of 8000 (32769 in decimal) and ending with a hybrid of Arceus with a hexadecimal identifier of 81ED (33261 in decimal).

Originally these Pokémon were thought to be 'pure glitch', in the sense that such Pokémon were completely unique, however further research has shown that all of these Pokémon share the same moveset including a relatively newly discovered glitch move, which possibly suggests that the game is reading the information from the same group of bytes, which possibly might be the game's attempt of reading information from other related variables such as the cries of other Pokémon.

It is notable that in these games the byte which manages what species the player encounters is unsigned. 8000 (32769) is actually half of FFFF (65535) which may suggest that some of the signed information about Pokémon with an identifier less than 8000 is read as a positive integer, and that some of the signed information about Pokémon with an identifier greater than 8000 is read as a negative integer.
