It's finally possible to capture Darkrai in Pokémon Brilliant Diamond and Shining Pearl. After only a few months after the game's official release, the event-exclusive legendary Pokémon are finally making their way to the game. It's currently possible to find and capture a Shaymin by using a Mystery Gift item. This is one of the three-event Pokémon that were exclusive to Pokémon Diamond and Pearl on the Nintendo DS. Trainers had to wait until Game Freak officially released these events to capture these Pokémon, although certain players have used cheat codes to access them early.
In the case of Darkrai, it acts as the polar opposite of Cresselia. While Cresselia is known to bless people's dreams with the feelings of light, Darkrai consumes their dreams and turns them into nightmares. It's only possible to obtain this Pokémon after obtaining the National Dex. This can be done by defeating the Elite Four and becoming the Champion of the Sinnoh region. Once that's done, the player will just need to wait until April 1st to collect it.
To obtain Darkrai in Pokémon Brilliant Diamond and Shining Pearl, trainers will need to claim the Member Card. This is an item that will be distributed through the game's Mystery Gift mechanic from April 1st to April 31st. Mystery Gift is the way for Game Freak to give content to new players over the internet. Head over to the inn in Canalave City with the Member Card and use it to open the door, upon entering there will be a bed for the player to sleep in.
Finding and Capturing Darkrai in Pokémon Brilliant Diamond and Shining Pearl
After sleeping in the bed, the player will wake up to a dairy in the room. Reading it will reveal the location of Darkrai. Now, head over to the sailor on the western side of Canalava City and he will take the player to Darkrai's location. Upon arriving on the island, make sure to save before interacting with Darkrai. Approach the dream-eating Pokémon and the battle will begin.
If it's anything like the original Pokémon Diamond and Pearl, Darkrai will be level 40 in this encounter. Arceus is also available in Pokémon Brilliant Diamond and Shining Pearl through a postgame update. Although, the player will need to have a completed Pokémon Legends: Arceus save file in order to access it. Arceus was never officially distributed during Diamond and Pearl's official run outside of a small movie promotion. It might be the only time to capture it legitimately outside of Pokémon Legends: Arceus. Shaymin, Darkrai, and Arceus are all part of the event Pokémon from this generation.
Pokémon Brilliant Diamond and Shining Pearl are available now on Nintendo Switch.
