List of Pokémon by Johto Pokédex number: Difference between revisions

* The five Pokémon added to the New Pokédex to create this listing (Ambipom, Lickilicky, Yanmega, Tangrowth, and Mamoswine) all evolve from their previous forms (which were included in the New Pokédex) when leveled up knowing a certain move. As these moves can be learned by the Pokémon at any point in the game, and not just after the National Pokédex is obtained, these Pokémon would otherwise display their Pokédex numbers as "???" despite evolving from a Pokémon with one (as the game displays regional Pokédex numbers in the status screen before the National Pokédex is obtained). All other Pokémon related to Pokémon found in this Pokédex (both baby forms and new evolutions) require a certain item to obtain them from their Johto Pokédex relative, which is able to be restricted to areas unreachable before the National Pokédex is obtained.

** It is unknown why this was done: in FireRed and LeafGreen, a Pokémon which would evolve into a Pokémon outside of the Kanto Pokédex was automatically stopped from doing so, most notably in the examples of {{p|Golbat}} and {{p|Chansey}}, though any Pokémon which evolves into a Pokémon not introduced in Generation I will be prevented from evolving, including Generation II and Generation III Pokémon hacked into the game (Generation II Pokémon that become Generation I Pokémon by evolving, however, are still allowed to evolve). This is also possibly because FireRed and LeafGreen locked out trading with non-Kanto games and disallowed trading of non-Kanto Pokémon until the Ruby and Sapphire were collected and the National Pokédex obtained, respectively. Possibly because this was viewed by many as a cumbersome task preventing players from raising their favorite Pokémon, it was dropped from HeartGold and SoulSilver.
