Trivia

 * Another term used in Pokémon GO players community to describe Pokémon groups from each region is Generations. Which also is valid but it wasn't officially referred in game nor by its creators on official social-media and information channels.
 * Therefore Kanto is Generation I, Johto is Generation II, Hoenn is Generation III and so on.
 * More about generations you can find here.
 * Common thing for Pokémon, that are not available with main release of each region Pokémon, is that those Pokémon either are legendary and/or mythical or have certain, special moves like Ditto, Delibird or Smeargle.

 * There has been Pokémon species from Hoenn added to game code since update 0.71.0.
