User:Pumpkinking0192/List of Pokémon that populate the same area in paired versions

This is a user subpage designed to prepare a page that may or may not be suitable for mainspacing in the eventual future.

If you like, you are welcome to make repairs to this page if anything is broken.

The purpose of this page is to try to build an equivalent to the "Counterpart Pokémon" lists that I see so often in people's userspaces (seriously, I've counted five already), but done in a plausibly mainspaceable format by stripping away all the speculation and going only by in-game availability. This was the best title I could come up with, but suggestions for alternatives are welcome.

In paired versions of the main series, there are many instances in which two Pokémon can be found in the same area at the same encounter rate but in opposite versions. These are usually version-exclusive Pokémon, but some Pokémon may still be found elsewhere in both versions.

Not all version-exclusive Pokémon are included in this article. Some, while arguably counterparts of each other, are found in different areas, and other local wild Pokémon have their encounter rates altered to accommodate a version-exclusive Pokémon. For example, in Pokémon Blue, Magmar is found with a 10% encounter rate in Pokémon Mansion, with no Red-exclusive counterpart found there. Instead, the encounter rate for wild Ponyta is 24% in Red and 14% in Blue to make room for Magmar. The Pokémon popularly considered to be a counterpart of Magmar — Electabuzz — is found with a 5% encounter rate in the Power Plant in Red. In Blue, this 5% is allocated to Raichu, which is only otherwise available in the wild in Cerulean Cave.

Third versions are not included in this article, as they frequently change Pokémon distributions and encounter rates to a large degree, making it impossible to draw a one-to-one comparison between them and their equivalent paired versions.

Generation I

The locations given are for the English Pokémon Red and Blue, which match the locations in the Japanese Pokémon Red and Green. The Japanese Pokémon Blue has different encounter rates and Pokémon distributions.
