Pokemon Brilliant Diamond & Shining Pearl has a few species that can only evolve when traded with another player, meaning you’ll need to buddy up to complete your Pokedex.
With the highly-anticipated Gen 4 Pokemon remakes Brilliant Diamond and Shining Pearl finally out in the wild, Trainers will once again be working towards their ultimate goal of catching ’em all, which is a pretty huge task.
As well as hunting down Legendaries and hard-to-find creatures like Spiritomb, evolution plays a big part in completing your Pokedex – but certain species can only be evolved into their final form when traded with other Trainers.
From old classics like Alakazam to Sinnoh region stars like Dusknoir and Rhyperior, here are all of the Pokemon in Brilliant Diamond & Shining Pearl that need to be traded to evolve, as well as details on how to do that.
Here are all of the Pokemon in Brilliant Diamond and Shining Pearl that can only evolve when traded, as well as any items they need to be holding:
|Pokemon||Evolved Pokemon||Special requirements|

|Clamperl||Gorebyss||Trade while holding a Deep Sea Scale|

If you want to trade with other Trainers in Brilliant Diamond & Shining Pearl, you’ll need to visit the Union Room, which is upstairs at any Pokemon Center. Here, you’ll have the option to trade either locally or online.
To trade locally with Trainers who are on the same network connection as you, take the escalators upstairs and talk to the middle nurse. Once you’re inside, approach a player with a speech bubble and talk to them to initiate a trade.
If you want to trade globally with other players online, take the escalators downstairs and talk to the middle nurse. Unlike trading locally, you’ll need to make sure you have a Nintendo Switch Online subscription to trade globally.
Once you’ve received your first badge in Oreburgh City, visit the basement of a Pokemon Center and you’ll unlock the ability to trade locally or globally by pressing Y at any point in the game, which is a lot more convenient!
