As Pokémon Black & White are part of the same generation as Pokémon Black 2 & White 2, it features the most compatibility with the games. This compatibility opens up after you have earned the first badge and have received the C-Gear. Not all of the features of Pokémon Black & White can be done on Pokémon Black 2 & White 2 however. Below is a list of the features and whether or not they work

• Battles & Trades . Battles can have the new forms within them, but the forms appear as their standard forms in Black & White, keeping the stats and abilities of the new form. The new forms need to be reverted to be traded to Black & White. This is possible on all modes; IR, Local Wireless, Wi-Fi and Random Matchup
• C-Gear's InfaRed functions. All of these functions, including the Friend Code exchange and the Feeling Check
• EntraLink: Pokémon Black 2 & White 2 no longer have the EntraLink functions of Black & White, having its own Funfest Missions
• Passing By: Pokémon Black & White can pass by Black 2 & White 2 using the C-Gear feature. Messages can be exchanged and Black 2 & White 2 users will often receive Support Powers when a user has been passed by
• Xtransceiver: Users of Black & White can video chat on the DSi and 3DS system with users of Black 2 & White 2
• Battle Subway: As the Battle Subway has been untouched by changes, players of Black & White can team with players of Black 2 & White 2
• Pokémon Musical: The multiplayer aspect of Pokémon Musicals is fully compatible. Pokémon Black 2 & White 2 users cannot use the new Pokémon forms
• Join Avenue: Despite Join Avenue not being in Black & White, when Black 2 & White 2 users communicate with Black & White users, the user's avatar will appear in Join Avenue wanting to open a shop or find a specific shop
• Memory Link: Finally, the Memory Link feature allows for specific data to be transferred to Black 2 & White 2 to allow for references of the Black & White trainer and unlocking various features

Pokémon Dream Radar is a 3DS game that was released to tie in with Pokémon Black 2 & White 2. This game allows for the capture of Pokémon and obtaining of items, which can then be sent to Pokémon Black 2 & White 2 using the Unova Link feature. First send the Pokémon to the DS games in the 3DS game, then receive them in the Unova Link. They will get placed directly into the Storage Box.

The levels of the Pokémon scale based upon the amount of badges you have got scaling from Level 5 at the start of the game, all the way up to Level 60 if you have defeated the champion.

Like in Pokémon Black & White, there is full compatibility to allow for the transfer of Pokémon from the Generation IV games. This is done through the PokéTransfer feature, in the building located in Route 15. Like in Black & White, this is done via a mini-game where you have to use a bow to shoot PokéBalls at the transferrable Pokémon.

There are various restrictions to this however. Items are removed from all Pokémon and put in the Generation IV bag. You also cannot transfer Pokémon who know any of the game's HM moves or the special Spiky-eared Pichu from HeartGold/SoulSilver.
