How to obtain Darkrai in Johto

Obtaining Darkrai

To obtain Darkrai, you must first capture or defeat Cresselia in Johto. Then build a full party of six Pokémon and make sure every member is asleep.

With the entire party asleep, go to New Bark Town and interact with your bed to enter the nightmare. Once inside, head to Dark Cave through the Route 45 entrance below Blackthorn City to find Darkrai.
