Arceus and Darkrai are coming to Pokémon Brilliant Diamond and Shining Pearl
The Pokémon Company is adding two new Legendary Pokémon to Pokémon Brilliant Diamond and Shining Pearl. Arceus is currently available in both games, Darkrai is coming soon.
To meet Arceus, you need a save file in Pokémon Legends: Arceus, on which all the main quests have been completed. Once you’ve been inducted into the Hall of Fame in Pokémon Brilliant Diamond or Shining Pearl and received the National Pokédex, you can get the Azure Flute from there, which you used to summon Arceus to the Pillar of the Spear.
Darkrai is obtained with a Mysterious Gift. Available from April 1 to April 30. After being inducted into the Hall of Fame, receiving the National Pokédex, and completing an in-game event for Cresselia, you can seek Darkrai on Newmoon Island.
