No, you can't. This is because Diamond is Generation 4, and Black and White are generation five. Like with all Pokemon games, Pokemon from later generations can't be traded to games from an earlier generation because the earlier generation doesn't have the new Pokemon on the Pokedex.
you can't get the pokemon off of pokemon black on diamond, but you can do it the other way around.
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.
No.
no
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 because diamond is form gen4 and black is from gen5
you cant because they gave you the orbs so if you got the pokemon on diamond or pearl you would transfer it to this game and then you give them the orb
It's actually a Pokemon from a hacked game, Pokemon chaos black. You won't get it on diamond.
you cant.
no
no you cannot
