On one side, Dialga's Roar of Time overpowers Palkia's Spacial Rend. Dialga has high Defense, since Steel-types boast the highest defense against most types and immunity to Poison.
On the other hand, Palkia's only weakness against Dragon is better than Dialga's type-disadvantages of Fighting and Ground. Dialga can't learn any moves by level-up to use against Fighting or Ground Pokémon. Also, Spacial Rend has high critical-hit ratio and doesn't need to recharge, unlike Roar of Time.
Stats: HP Atk Def Sp.Atk Sp.Def Speed
Dialga: 100 120 120 150 100 90
Palkia: 90 120 100 150 120 100
Therefore, a strong-enough Sp.Atk move like Blast Burn or Palkia's Spacial Rend stands a chance against Dialga, while Outrage or Dialga's Roar of Time is effective against Palkia.
Dialga has a higher Def, while Palkia has a higher Sp.Def, so it depends if you prefer your a legendary dragon to have either a higher physical or special defense.
palkia because according to the Pokemon diamond and pearl guide book dialga and palkia have the same levl of stat s for all of them but sppeed which palkia is better at.
However, Dialga just looks better and face it, which is better, a vicious dog? or a pink cudely dinasaur!?
The real question is, which is better, Entei Suicune or Raikou??? (Entei by far!)
well... I like Palkia better so I say Palkia!
In some ways Dialga is better because of its roar of time: Roar of time is stronger then spacial rend but Roar of time you have to wait a turn but spacial rend you dont have to! And so i do think Palkia is better cause its bigger and i would personaly like to control space than time but at the same time i wouldnt want a purple dragon so i say both a great!
Dialga
Palkia is way better than that fatty dialga
I think Dialga is WAY better than palkia but.dialga's special k.o. move is roar of time and palkia's special k.o. move is spacial rend.
No Pearl Is Better because palkia and dialga are the same put palkia has 1 bar more speed. Also because dialga has roar of time palkia has spaial rend roar of time does more damage but spacial rend does over half of roar of time and roar of time has to recharge
Perhaps they think Dialga is better than Palkia, or they like the Pokemon that are exclusive to Diamond better than the ones that are exclusive to Pearl.
I think it is Palkia
Giratina will of course kill both Dialga and Palkia even if the match is 2 on 1!!!
palkia
Dialga you can barely hear palkia's.
seriously dialga is nothing against palkia belive me i have tried
palkia is waaaaaaaaaaayyyyyyyyyyy better because he/she can control time AND SPACE and dialga can only control the stinking time PALKIA IS BETTER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Palkia is way better. i aggree with the person above. Her stats are the same as dialga's except for the speed, palkia is WAY faster than dialga therefore making her a better choise. achully palkia is a boy or dialga would be g** for attacking a girl
Dialga is not as strong as palikia. Dialga is weaker against more types than palkia and palkia has a little better stats than dialga, hope this helped.
Garatina has more hp and is better than dialga, but i dont know about palkia, ive only got garatina and dialga.
Well, this depends on the stats. If palkia wants to defeat dialga, then it better have a high sp atk and dialga would need to have a low sp def. But if dialga survives the hit of palkia, then of course, roar of time will kill palkia...
dialga is not better then palkia people just say he is. really i think there the same and none of them are better.:P
Dialga is a better Pokemon then Palkia. that's why.
I think Dialga is WAY better than palkia but.dialga's special k.o. move is roar of time and palkia's special k.o. move is spacial rend.
No Pearl Is Better because palkia and dialga are the same put palkia has 1 bar more speed. Also because dialga has roar of time palkia has spaial rend roar of time does more damage but spacial rend does over half of roar of time and roar of time has to recharge
yes it is because palkia is dragon and water and dialga is dragon steel so dialgas steel moves arent very effective.
