- Main article: N's Pokémon
After witnessing the "Meeting Friends, Saying Good-Bye" event, players can encounter several of N's Pokémon from Pokémon Black and White. However, in order to encounter such Pokémon, the player must have defeated the main storyline from Black and White.
There are several special aspects of N's Pokémon:
- N's Pokémon may not be renamed
- It is under the ownership of N with the ID number of 00002
- When in battle, the Pokémon will glitter, similar to encountering Shiny Pokémon
Players can send props from Pokémon Black and White over to Pokémon Black 2 and White 2. After listening to the Pokémon Musical owner in the "Farewell, Beloved Sister" event, he will give the player the option to accept the prop case or deny it. Accepting the prop case, the player will obtain any props from Black and White, receiving props the player has yet to obtain in Black 2 and White 2.
There are other effects of Memory Link. One is the mentioning of the name of the protagonist from Pokémon Black and White. Usually, before using Memory Link, the protagonist is only referred to as "a trainer." However, after using the link, several characters, such as N, Bianca, and Cheren, will say the protagonist's name.
Another is the protagonist's room from Black and White. Any certificates obtained from completion of the Pokédex, as well as trophies from the Battle Subway, will appear in the protagonist's room.
