first you need to beat the elite four then the Pokemon champ (Cynthia)then talk to cynthias grandma in celestic town she will tell you about palkia and dialga then you also need the adment orb and the lustrious orb in mt. corenent and when you've done all that you go to the sky pillar and there will be a blue portal that is where dialga is and after you capture him leave then come back there will be a pink portal and palkia is there and you capture him.note:if you accidentally beat dialga and palkia they will appear again after you beat the game.
In Diamond you can get Dialga, but you find him in the Spear Pillar after you beat Cyrus of Team Galactic. Im Pokemon pearl you find Palkia.
the legendary beasts, entei, raiku, and suicune, i am assuming You can find them all at the tower (you will get there in the plot so you'll figure out which tower) and you can get one there and then the other 2 will be roaming and you will find them randomly. after you find them the first time you can check in the pokedex and it will say where they currently are. do not fly because that will change their location.
palkia was not created until Pokemon pearl was released
Palkia you get in pearl at the spear pillar. Dialga you get in Diamond at the sear pillar. Groudon, Kyogre, and rayquaza all need action replay or use pal park.
TheSinnoh Dex Legionaries are:(Rotom),Uxie,Mespirit,Azelf,Dialgia,Palkia,(Heatran),(Regigigas),(Giratina),(Cresselia),(Phonie),(Manaphy),(Darkrai),(Shaymin),and (Arceus) (Names in ( ) are National Dex in D/P and in the Sinnoh Dex in Pokemon Platinum)
You cannot catch palkia in pokemon diamond!
The lustrous orb and the other orb are on the way to spear pillar but you have to take one different tunnel!!!!
Palkia is impossible to find in Shadows of Almia as is Dialga.
check
you cant
You can not find Palkia on Pokemon diamond unless, you use action replay that might not work or if you trade with somone that has pearl.
Yes you can. You can either find a picture of palkia in Cynthia's grandma's house (i think) or trade with someone who has Pokemon pearl and has palkia.
