you cant.
Yes, it is possible to trade your UK Pokemon from Diamond into the Japanese Pokemon Black version. However, you need to beat the whole game in Pokemon Black & White to be able to trade Pokemon from the other generations.
I can answer all sorts of question for Black, White, Pearl, and Diamond Versions of the Ds games. I can also tell you when or how to evolve certain Pokemon.
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
Yes you can but you can't trade from black to pearl or white to diamond because the games are not compatible with each other because the Pokemon in black and white will come up as ? in the pokedex's of the other games. But you just can't trade to pearl from black or white sorry. However you can trade between black and white using infrared connection. (the other games don't have infrared that's why the game cancels the trade between pearl and black or diamond to black).
As far as I know, Pokemon on Pokemon Black and White have to stay on those games, as for Pokemon HeartGold and SoulSilver, you can not only migrate Pokemon from earlier generations of games, you can also trade with Pokemon Platinum and Diamond and Pearl. Still, the Pokemon on Pokemon Black and White look cooler! :)
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.
Eelektrik does
no
They are Pokemon in Pokemon black and white versions and they are in the 13th Pokemon movie
You cannot trade between the new games of Pokémon Black and Pokémon White and the previous games of Pokémon Diamond and Pokémon Pearl and there is no way for you to trade Pokémon from "Pokémon Black or Pokémon White" over to Pokémon Diamond or Pokémon Pearl. But you can transfer any Pokemon from the old ds games TO black or white .
