EV Love

This is a list of Pokémon by number of regional Pokédex appearances. It takes into account only the most expanded forms of each region's Pokédex, as three of the six have been added to in some way (Johto, Sinnoh, and Unova). No expansion has ever resulted in the removal of a Pokémon. This also considers the Kanto Pokédex separate from the National Pokédex and the three categories of the Kalos Pokédex as a single listing. Although numbered, Pokémon after #202 in the Hoenn Pokédex are not considered part of it.
