There are several Pokémon that you can find by playing Pokémon Go. Many of them only appear in specific ways or at certain times of the year. You may also find a unique form of a Pokémon you've already caught, such as a Pokémon Go from Alola or a form of Galar. If you are looking for a Mr. Mime of Galar, you will need to be quick. But what are the chances of a brilliant Mr. Mime from Galar? Here's what you need to know about catching a shiny Mr. Mime from Galar in Pokémon Go.
While the original form of Mr. Mime has a glossy form, the Galarian form of Mr. Mime does not. If you encounter this Pokémon by completing special activities or timed research or appearing in the wild during an event, there is no chance of encountering a brilliant version of Galarian Mr. Mime. Only a handful of Galar's Pokémon have their brilliant versions added to the game. The glossy version of a Pokémon typically appears alongside more significant events, so we may see it in the future.
Galarian Mr. Mime was introduced through a special research ticket in 2020. So the glossy version for Pokémon may be available during the upcoming holiday season in 2022, but we don't really know. However, it would make sense to release a brilliant version of Galarian Mr. Mime for the Winter Holiday 2021 Part 2 event.
