Editing Pokédex (section)

==National Mode==
National Mode is a mode that was officially added in the third generation since in Pokémon Gold, Silver, and Crystal it was not the national Pokédex (It was already made to obtain data on Pokémon from Kanto without the need for any additions). This Mode allows you to obtain data on a Pokémon that is not actually from that region or that is not in the initial Pokédex.

These are the various methods to obtain the National Pokédex differs between the games:
