There are a couple of ways, you can get it by going to a Nintendo event or you can get it by transfering it over from pokmeon ranger shadows of almia by clearing the speacial mission liberate the tower on Nintendo wi-fi. You could also use action replay but i don't recommend it.
I thinkthe last boss you fight with is darkrai but im not very sure.
You got to go to iron island and at the end of it you find it
To get Darkrai in Diamond and Pearl you needed to obtain a member card from a live Nintendo event. The player was then able to encounter Darkrai on Newmoon Island.
No
Only at a Japanese event
Pokemon event.
40
yes he was an event for diamond and pearl. and possibly platinum
You have 2 Nintendo DS then send the darkrai (You have to have the mystery gift in diamond or pearl)
You cannot find the Pokemon Darkrai in Turnback Cave in the game Pokemon Diamond. Instead you can find him in Newmoon Island.
Darkrai is a dark type of Pokemon. You can catch one in Pokemon Diamond version on Newmoon Island but you need a membership card.
