More research is needed for this article.
Reason given: Document more effects of it. Can a Glitch Pokémon evolve if its sprite and name are "stable" enough? Are there many glitch cries available for Glitch Pokémon? List Glitch Type Sprites that could cause interesting effects. Study the causes and effects of the corruption of the PC Pokémon Selection in Fr/Lg. Test again the effect of Pokédex entries of Glitch Pokémon.
This article is a list of glitch Pokémon, with transcribed names.
Feel free to add more glitch Pokémon (of any language) to this list.
