Well it just depends on opinion,but I think Palkia is stronger.
Palkia is better
Palkia of course!
well it doesn't really matter because they are both the same strength me personly i like diagla better because its looks cooler but there the same strength so there is no bother fighting over who is stronger i love diagla's roar of time its better then palkia's
with palkia
diagla is stronger because it can use roar of time on palkia and kill it in one hit. But palkia can use special rend and kill diagla in one hit right? WRONG!!! Diagla is also a steel time which dragon moves aren't good against. It all doesn't matter on the moves It matters on the stats
diagla is a steel dragon and palkia is a water dragon
in pearl palkia in diamond diagla
not both you can only get one of them
They are both good but.... i have Pearl and my friend has Diamond. He says Diamond is better becuase, Dialga is Steel and Dragon which is stronger than Water and Dragon for Palkia. so i guess Diamond is a little better than Pearl. But pearl is good too :]]Actually i did some research and Water is better then steel because Steel can mold from water. that makes Palkia better then Diagla. But Diagla is more powerful. i have Diamond and Pearl and i beat Pearl all ready im working on Diamond.
yes, at the spear pillar
No, they´re like symbiotic Pokemon
if you have pearl, Palkia. Diamond, you get Diagla. Platinum, you get giratina
