GTS in Jublife City or Pokemon center to trade with a friend.
You can't but if you have Pokemon Pearl, you catch Palkia and Giratina and trade Dialga in Diamond. Same for Diamond, just Trade Palkia to Diamond. In PlatinumCatch Giratina, Uxie, Mesprit and Azelf. Go to Celectic Town Ruins and press A at the painting. Cynthia will talk to you. Speak to the elder and read the book, go to Spear Pillar and Dialga and Palkia's Portals will be there.
In Diamond you get Dialga at the spear pillar, after defeating Cyrus. In pearl you have to trade. In platinum, it's behind Giratina, standing next to Palkia.
in dimond/pearl you go back to spear pillar to get them then you give them to palkia/dialga depending on which game youre playing (dialga in diamond/palkia in pearl). in platinum you use them to summon palkia AND dialga to spear pillar.
You can't unless you go to the trade center and offer dialga or any legendary Pokemon. or you can find a friend with Pokemon pearl and ask to trade. hope this helps
I'm sorry, but you can't. but if you want to catch it for your pokedex, you can ask a friend to trade dialga for palkia and then trade it back. if you want to see it you can go to celestic town and in a house there is an older lady who will show you a book whit a picture of palkia.
you have to go to hearthome and gain dialga or palkia
you go to spear pillar to catch dialga/palkia
you capure palkia at the spear pillar in mt.cornet, if you want to capure dialga you go to the same place in Pokemon diamond version.
yes you can you have to get arceus in a link trade then go to the ruins of alph and talk to the manager there and he will take you down to the ruins and then you will disapeare and go to the sinnoh ruins and then you have to choose between Palkia, Dialga and Giratina.
You have to catch Dialga if you have Diamond or catch Palkia if you have Pearl and then go to the the lake shore near Pastoria City and go down the road on the right and that guy that doesn't let you in until you catch a Dialga or Palkia will let you through. Then just ride on and go to Sunyshore City! :D
According to my gaming 'professional' son, you have to trade with someone that has Pokemon Diamond to get Dialga. To get Palkia, you have to go through the storyline until you get to Spear Pillar. Then, battle Cyrus for the last time and you will have one opportunity to catch Palkia. If you miss him, then you'll have to reload or start over so be sure to save just before the battle with Cyrus.
If you have already caught Palkia or Dialga (Palkia-Pearl Dialga-Diamond) then that means that you have already defeated Team Galactic, and you can go to the Pal Park, try to find more legendaries, or anything you want to do, but if not then you have to go to the place where you will catch either Palkia or Dialga and right before you catch them you will encounter Cyrus, the leader of Team Galactic. If you want to know where to find Palkia or Dialga and encounter Cyrus try looking up something like "where do you catch Palkia or Dialga?" or something like that.
