OK. Here's something to clear all this up. Palkia and Dialga are both good. But everyone asks "Which is better?" I, however have the answer. Many say Dialga, but I say Palkia. No, I am not just saying this because I have Pearl. Because I have Diamond. Palkia is resistant to more types than Dialga, being two types that aren't sub-typed to each other. (A sub-type is something that is much simalar in weaknesses, moves, and resistances. Example: Ice and Water; Flying and Dragon; Steel and Rock.) Dragon and Steel, are sub-typed. Fire, normally being weak against Dragon, is now stronger to Dialga, because it has steel as a type, which is resistant to Fire. Roar of Time, Dialga's main move, is also weaker than Spacial Rend (Or whatever Palkia's move is called)
ya i say Palkia just because Dialga looks cooler doesnt mean it's better. also to support my reason is because Palkia has resistances and just plain better stats (more speed, rest of them are same) but i still go with Mewtwo lol
The reason Palkia faints and Dialga doesn't is that Palkia is weak to dragon types and dragon only has regular effectiveness on Dialga. However, I still say Dialga's better. I owe my awesomeness to him. Besides, Palkia is this super-powerful legendary, and it is pink. Sad.
Dialga, was able to hurt Palkia when they fought in Pokemon The Rise Of Darkrai. BTW the movie, is excellent. Besides, Dialga is steel, and Palkia is water, so doesn't Dialga have the upper hand? Either one of them's pretty powerful, but Arceus can destroy them. To me, Dialga's better, who do you think?
