you are unable to send any items from the past games to pokemon black/ white
you can't get the pokemon off of pokemon black on diamond, but you can do it the other way around.
No.
Migrate from Pokemon Sapphire to Diamond then Diamond to Black/White
No you can't trade with black to diamond but you can trade from diamond to black using the poketransfer lab. (you will have to have beaten the game before you can use the poketransfer lab). Hope I helped this is luke127 signing off.
you cant.
>You can send 6 pokémon from diamond to black(but not back!). On route 15 of Unova there's a building. Go inside and talk to the man. You can connect to diamond and send six pokémon each time you want (it's not really trading but sending).
You can't, because Pokemon black was made after Pokemon diamond, Pokemon diamond wouldn't be able to recognise any of the new Pokemon. So to solve this problem they stopped all trading from black to any other game apart from white. You can however get your Pokemon from diamond to black by using the poke transfer, yet you need to have won the league for the first time to be able to do this.
no
I don't think you can because Pokemon Diamond didn't have the new Pokemon that only appear in the Unova region. But, once you have completed the Pokemon League on Pokemon Black/White you can go to a science lab in route 15 and transfer Pokemon from Pokemon Diamond/Pearl, Pokemon Platinum, Pokemon Heart Gold/Soul Silver to your game.
Dawn never was on pokemon black and white she was only on pokemon diamond and pearl.
you have to transfer from diamond, pearl, or platinum or trade with a friend
It's actually a Pokemon from a hacked game, Pokemon chaos black. You won't get it on diamond.
