when you have battled the 3 main bad guys in the mountain you can fight and capture dialga. This is ponly possible on Pokemon diamond on pearl it is something else i cant remember the name of. You can other wise trade or cheat to get it.
diagla and murkrow
in pearl palkia in diamond diagla
Yes. You can only get GLAMEOW'S in pearl and STUNKY'S in diamond. Also you can only get PALKIA in pearl and DIAGLA in Diamond
Trade for a diagla for somebody who has diamond.
Piplup is obtained as a starter in Diamond and Pearl or through trades.
Not much. Pokemon diamond and Pokemon pearl have different Pokemon. for example, in pearl you can catch a glameow but not a cranidos and in diamond you can catch a cranidos but not a gleameow. And at the end of pearl you can catch Palkia the legendary and at the end of Diamond you can catch Diagla. But the games are basically the same. And there you go.....
Palkia and Giritina can learn dragon claw.
trade it from soulsilver
They are both good but.... i have Pearl and my friend has Diamond. He says Diamond is better becuase, Dialga is Steel and Dragon which is stronger than Water and Dragon for Palkia. so i guess Diamond is a little better than Pearl. But pearl is good too :]]Actually i did some research and Water is better then steel because Steel can mold from water. that makes Palkia better then Diagla. But Diagla is more powerful. i have Diamond and Pearl and i beat Pearl all ready im working on Diamond.
Sorry, but Entei can not be obtained in Pokemon Diamond and Pearl itself, you must transfer it from old GBA games and use the Pal park in DP to catch him.
