If you want offense and diversity, Palkia.
If you want defense and decent offense, Giratina.
Garatina, Dialga, Palkia, Darkarai, Shaymin,
Garatina has more hp and is better than dialga, but i dont know about palkia, ive only got garatina and dialga.
In platinum, you capture garatina 1st, then dialga, then palkia.
I'ts Palkia and you can't get them in Pokemon heart gold and soul silver sorry!
if you want more Pokemon yes because different Pokemon appear in each game apart from dialga and palkia
Garatina,Dialga,Garchomp,Dragonite,Salamance,and last but not least Palkia. Make sure you raise dialga and palkia's stats during battle-Andres Viveros
I don't think so but palkia,diagla,garatina,lucario and some other fighting type might learn it
Garatina can be found in the spring path on Route 214 after you beat the Pokemon Leauge on regular Diamond and Pearl. If you have platinum, Garatina (origin form) is found at the spear pillar when you would normally go and capture Dialga or Palkia. If you go along with what ever goes on up there, you can go through the portal to the distortion world with Cynthia to capture Garatina at the end at I think it's level 47 for all of the versions. And that's where Garatina is located. :)
You catch Garatina, Dialga,Palkiia,and all the lake Pokemon but mainly Garatina
The following Pokemon should be unlocked: Zapdos: Get him in rooms Mewtwo: Get him in rooms Mew: Get him in rooms Garatina: Exploder, Cheat, Hack, Trade Ect. Dialga: Get him in rooms Palkia: Get him in rooms
Dialga is a better Pokemon then Palkia. that's why.
