Trade with someone that has a Palkia. Its as simple as that :)
you cant
You can't catch Palkia in Pokemon Diamond, you'll have to trade with Pokemon Pearl
no, unless u trade
Spear Pillar.
dalaga(dimond) or palkia(pearl) and azlef mesprit and uxi(sorry about the spelling)
You need to fight Dialga and palkia where u fought them in dimond and pearl and then after u defeat them you get sucked into the reverse world.
Palkia is in a cave, but when you reach the end, Palkia will be somehow outside.
i think its charizard (if choose) kyogre,groundon or rayquaza and dialga or palkia from dimond or pearl
Pokemon to be exact dimond and pearl version on a ds
Use it on Palkia.
You cant get palkia in diamond if you play diamond and you trade you STILL cant get palkia only in pearl you can get palkia
