Rarest Pokemon in Pokemon GO are event exclusive Pokemon, sometimes with special moves as well. These events come and go, making it usually impossible to go back and get them.


However, if you keep an eye out for these events you can be sure you don't miss out. Here are the events to watch out for and some of the rarest Pokemon in Pokemon GO.


Rarest Pokemon in Pokemon GO



Community Day


Community Day is a special event where a specific Pokemon is featured. The featured Pokemon will have an increased encounter rate, as well as an increased Shiny encounter rate. The featured Pokemon will also learn a special event exclusive move when it evolves. Shiny Community Day Pokemon with the exclusive moves are among the rarest, as there is only one day you can acquire that Pokemon with the specific move.



Research Breakthrough


Research Breakthroughs will sometimes reward you with a Legendary Pokemon encounter. The list of available Legendary Pokemon cycle each month or so, making these Pokemon among the hardest to acquire. Sometimes they'll make an appearance during special Raid events, such as Entei, Raikou and Suicune.



Region Exclusives


Region exclusivity is a major theme in the Pokemon franchise, and Pokemon GO is no exception. These Pokemon are relatively common in their respective regions, but are impossible to acquire elsewhere.

Event Exclusives


There are also Pokemon that were featured in one-off events, making these particularly rare.



Armored Mewtwo


Armored Mewtwo was available in Raid Battles for a limited time in preparation for the Team Rocket Invasion event. It is unknown when we'll have another opportunity to catch this special Mewtwo.



Hat Pikachu


Pokemon GO often features collaborative events where a Pikachu with a special hat will be offered. There are also various other Hat Pikachu for in game events, such as the Festive Pikachu. There will be another chance to catch some of these Hat Pikachu for all players during Pokemon GO Fest Yokohama, so be sure to look out for these. Otherwise, they're only available for the event.



Delibird


Delibird is only available during the Holiday event, and is impossible to obtain any other way. It's the only regular Pokemon that is event exclusive.



Smeargle


Smeargle isn't particularly hard to find, but will only appear when you look at your AR Photos. It will photobomb your AR Photos, and if you spot it, you can check around you for it to spawn as a wild Pokemon. This is the only way to get Smeargle, and is entirely possible to miss if you didn't know where to look.



It might be too late to get some of these exclusive rare Pokemon, but you can keep an eye out on the Pokemon GO Twitter for updates and new events so you don't miss out in the future.
