You'd have to trade with someone who has Pearl to get Palkia in Diamond.
Arceus' event was never run, there's no legitimate way to obtain him, though you can use a cheat device to trigger the event.
Dialga (Diamond Version) Palkia (Pearl Version) Uxie, Mesprit, Azelf Darkrai, Arceus, Shaymin

With event but it passed. So trade from Diamond,Pearl or Platinum.
Sorry to say, but no, you cannot catch a Palkia on Diamond version. You catch a Dialga on diamond, and Palkia on pearl. You would have to trade to get one.
It would be Arceus but since Arceus is not available yet in any game, it would have to be Dialga and Palkia.
Palkia, (Dialga for diamond) Arceus, and Spiritomb are some of the best.
where is arceuse in Pokemon platinum version whe you chach giritina,palkia,and diagla
no but can be traded from pearl
Yes you can get Arceus if you have a Pokemon platinum,diamond,or pearl and you have giratina dialga and palkia trade them to your Soulsilver and then a mountain will appear somewhere and then Arceus will be in there
Arceus,Giratina,Dialga,Palkia,Heatran,and Mewtwo
the legendary Pokemon in diamond and pearl are dialga and palkia.
