Rarest Pokemon in Pokemon Go 2023

Pokemon Go has over 700 Pokemon in the Pokedex, but not all of them are easy to catch. Some Pokémon are only available for one day, while others can only be found during a Raid Battle. Here are the rarest Pokémon in Pokémon Go in 2023.
There are several ways to encounter a Pokémon in Pokémon Go – in the wild, while hatching an egg, in a Raid Battle, and in Field Research. Pokémon that are commonly found in the wild are considered common.
A rare Pokemon is one that can only be found under very specific circumstances. For example during a special event or a raid battle. There are versions of Pokémon that were once available that will never return to the game.
One of the rarest Pokemon in Pokemon Go 2023 is the different versions of Pikachu. Some of the Pikachu variants are Fragment Hat Pikachu, Detective Pikachu, and 5-Year Anniversary Pikachu. These were only available for a certain period of time and will not return to the game.
Spiritomb is another rare Pokemon. It was only available during the Halloween event and it is not possible to encounter it again.
How to Encounter Rare Vivillon Patterns
Vivillon is a Bug and Flying-type Pokémon from the Kalos region. It is one of the rarest Pokemon in the game and one with the most versions. There are 20 different possible Vivillon patterns.
To obtain Vivillon, players must pin postcards from different regions. This will unlock the Vivillon from that region. Players need friends from all over the world to complete the collection.
If a friend sends you a gift, pin the postcard. After that, the game will show you that Vivillon has been unlocked for you and will appear in the wild. Once you have enough postcards in your collection, you’ll get a chance to encounter another rare Pokemon, Scatterbug.
