List of Pokémon by generation

This is a complete list of the Pokémon which appear in the National Pokédex as of Pokémon Diamond and Pearl. This list is the most-complete numbered list appearing in the games, covering all of the Pokémon. Each region in the games uses its own modified Pokédex, but this single, unified list has appeared in every game to date.

For convienience the page has been edited to break the list into four parts, each representing a different set of released Pokémon over the years. In each game the newest starting Pokémon hold the position of 001 in each game's regional Pokédex. For example, in Pokémon Gold and Silver Chikorita is the first Pokémon listed while in Pokémon Ruby and Sapphire this position is held by Treecko.
