Glitch City Laboratories Archives

This project known as the TypeDex is currently a listing of all the glitch types in English Pokémon Red, Blue, and Yellow.

Some of the entries may have additional articles, with details such as which glitch Pokémon and which glitch moves have the types. These are shown in Blue.

All glitch types in Pokémon Red, Blue and Yellow have no weaknesses but glitch moves with glitch types are always 1× effective against other Pokémon.

All glitch moves beyond hex:80 have the name of the glitch move modulo 128, for example glitch type 0x81 is referred to as a Fighting-type move; which is the same name as the valid type 0x01.

Many of the names of glitch types are random or based on the RAM. For this reason all glitch types have been given sample names; which are only one example of the glitch move's name.
