The Pokémon Company has announced that as of now, you can get the legendary Pokémon Arceus and Darkrai – from Pokémon Legends: Arceus – in Pokémon Brilliant Diamond and Pokémon Shining Pearl.You’ll need to own a copy of either remake as well as a copy of Pokémon Legends: Arceus.
Furthermore, the games must be up to date with version 1.3.0, which was released on March 15.Getting Arceus requires you to complete the game of the same name, or at least have the main missions done.
In Brilliant Diamond or Shining Pearl you’ll need to have entered the Hall of Fame and obtained the National Pokédex.When that’s all done, simply return to your room in Diamond or Pearl and you will get an item called the Azure Flute.
After that, you need to go to the Spear Pillar at the top of Mount Coronet, whereby Arceus will show up, and you’ll have to battle the legendary Pokémon to capture it.It’s a similar situation with Darkrai, only you’ll need to use the Mystery Gift feature in Diamond or Pearl, which The Pokémon Company explains is “available between the new moons”.
