The Darkrai event in Pokémon Brilliant Diamond and Shining Pearl has finished, but does that mean it's gone forever? Darkrai is a Mythical Pokémon, which means that it can only be acquired through outside means, with the limited-time Member Card event being the main method of acquiring it in Pokémon Brilliant Diamond and Shining Pearl. Arceus and Darkrai joined Pokémon BDSP as part of post-launch events, but Darkrai's event is now done, and the path to Newmoon Island has been shut for the time being.
From April 1-31, it was possible to acquire a Member Card in Pokémon Brilliant Diamond and Shining Pearl through a Mystery Gift event. Once the player has defeated the Elite Four and the Champion, they will earn the National Dex. With the National Dex in hand, the player can use the Member Card to enter the inn in Canalave City and sleep in one of its beds. This will allow the player to travel to Newmoon Island, where they can face Darkrai in battle, and attempt to catch it.

It's unlikely that the Darkrai event will return
