How to obtain Darkrai in Kanto

Obtaining Darkrai

To obtain Darkrai, you must first obtain Cresselia. Build a full party of Dark-type Pokémon that know the move Rest.

Once you meet these conditions, go to the S. S. Anne and enter the first door from the entrance, where you will find a girl and a bed. Interact with the bed to sleep; Darkrai will appear during the nightmare.
