migrate them through palpark after you get the national pokedex.
You don't
No you don't.
Pokemon Pear [and Diamond] is located in the Sinnoh region. You will not be able to get to the Johto region unfortunately. Sorry.
You can't, only Sinnoh is available in Diamond.
You can't get to Johto region in Pokemon Diamond/ Pearl, but you start there in Heartgold/ Soulsilver.
it is not possable
I don't think you can.
Sorry No you can see some of the johto league Pokemon on Pokemon diamond and pearl if you go to the battle tower. ive seen a totodile and a cynaquil already. ;)
No because it is a sinnoh Pokemon not a kanto, johto, or hoenn
The Apricot Man (Kurt) is only in Johto. Sorry. :(
The oldest Pokemon games to feature Johto are Gold, Silver, and Crystal. FireRed and LeafGreen partially feature Johto after you beat the Elite Four. The newest games to feature Johto are HeartGold and SoulSilver.
OK I'm going to improve the answer to this question because the guy before me wants to be an a#$ about it. I don't think you can catch Pokemon from Johto in Pokemon Diamond or Pearl, but I do know they are coming out with a remake of Pokemon Silver, Gold, and Crystal. It is for the DS so you will have to trade between someone with a Silver, Gold, or Crystal version to your Diamond and Pearl game.
