I saw this ad on Pokemon.com and it said I could get Darkrai for my game. I followed the instructions and got Darkrai into my party (best thing EVER :D) but when I checked my Pokedex, it didn't say Darkrai was in my Pokedex! I really don't get it...
Do you have the National Dex? If you do, switch to it.
>After obtaining the upgrade, the player can switch the Pokédex type from the National Pokédex to the Unova Pokédex at will by simply tapping "SELECT" in the lower portion of the touch screen or by pressing the SELECT button on the DS System. -Bulbepedia
Hope This Helped :D
It was in your pokedex, you just have to switch pokedexes by pressing the select button. He is #491
hop£ this helps! :D
You need to obtain the National pokedex. Darkrai isn't in the Unova Dex.
