Dialga needs to be traded in from Diamond, Pearl, Platinum, Heartgold or Soulsilver.
You canot a dialga egg in pokemon black and white.
you have to transfer from diamond, pearl, or platinum or trade with a friend
No.you can oly get them if you transfer them from pokemon platnum,pearl,or dimond9the pokemon transfer building is around black city if you have pokemon black or white forest in pokemon white,
PokéTransfer or Dream World, none in Black. Or White. :|
you get zekrom in Pokemon white version and resheriham in Pokemon black.(in my oppinion, it should be the other way around, zekrom in Pokemon black, and resheriham in Pokemon white version) IT IS JUST LIKE PUTTING DIALGA IN POKEMON PEARL AND PALKIA IN POKEMON DIAMOND.
You can't catch Dialga in Pokemon White. After you beat the the Elite 4, you can use the PokeTransfer to receive a Dialga from Pokemon Diamond, or Platnium.
You can transfer your Dialga, Palkia, and Giratina to your Pokemon black or white version game (NOTE: ONCE YOU HAVE DECIDED TO TRANSFER THE POKEMON TO THE POKEMON TRANSFER LAB IN POKEMON BLACK OR WHITE VERSION, THE POKEMON THAT YOU SENT ARE UNABLE TO RETURN TO YOUR PREVIOUS GAME) or you may just use cheat codes on your AR to find any Pokemon that you desire whether it is a shiny Darkri to an average Pikachu. Have fun!
Trade with someone who has Black 2 or White 2, or transfer it from a Generation IV game.
Transfering it from a previous game is the only way you can legally obtain it.
link trade a pokemon from kanto hoen,etc for dialga
You can't catch Dialga in Pokemon Black. You need to trade for it or transfer it from the older Pokemon DS games.
Sorry, you can't catch dialga in Pokemon black. You need to trade with a friend from an earlier game.
