Costume Pokémon – what exactly does that mean? Well in the case of Pokémon Go this means a Pokémon that is wearing some sort of accessory giving it a slightly different visual appearance. In contrast to different Pokémon Forms, Costume Pokémon don’t receive any stat changes from the added accessory.
Over the history of Pokémon Go, there have been numerous events featuring Costumed Pokémon. Below is a running list of these Pokémon.
PRO TIP: The in-game search tool allows the use of ‘costume’ to return all Costumed Pokémon in your box.
