With Diamond & Pearl being on the DS which contains a slot for GBA games, there is an extra feature utilising this. When you have certain Pokémon games in your GBA slot after obtaining the National Dex, some new Wild Pokémon appear in certain areas for the period of having the respective game in the GBA Slot. However these areas do not appear in the Pokédex so this page will be used to help you with the Pokémon Locations for each of the games. These Pokémon and their evolutions are only available with this method:

Ruby | Sapphire | Emerald | FireRed | LeafGreen | All
