Dialga Vs Palkia

Which do you think would win?

For me, Dialga, because its faster and can hit with a dragon attack. Super effective!

Roar of Time is way better than Spacial Rend!
Definetely Dialga!

I think Palkia. Depends though on many things. Dialga's Roar makes it stop for 1 turn, whilst Spacial Rend has a high Critical hit Ratio. It would go... If we went with the Power:

Turn 1:
Roar of Time: 300 on Palkia (Super Effective)
Spacial Rend: 200 (Critical Hit) on Dialga

Turn 2:
Waiting, due to Roar of Time
Spacial Rend: 100 on Dialga.

So, it would be fairly balanced, but I prefer Palkia.

Oh so thats how it matches up....
But Dialga and its Roar of Time is still way cooler!

Opinions, so I say Spacial Rend is cooler. The name sounds so deadly, Roar of Time... Doesn't, sounds like a move that doesn't do much.

There is about 40% chance of Spacial rend for critical hit

But if it does, it is even better, and matches up. That is a 2 in 5 chance, which is nearly half, so my practicality is nearly right, and if it works, which is more than possible, it evens it up.

Well, Palkia can also learn Surf. Which would hit Dialga quite hard

Would it?
Cause Dialga is a metal type -
It is weak against Fire!

Not really. Dialga is part Dragon, making Water moves do half the damage. Metal moves do half to Palkia though, due to the Water type, but Dragon does Double, like in my approximate calculations of damage caused to both.

Palkia also learns fly(strange)but that doesnt do much

Does it? Well, it does have wings...

My Palkia knows Fly!

Palkia would win (especially if it was level 100 against a level 1 dialga.)
Palkia and Dialga are equal except that Palkia has more speed than dialga.

But Dialga has more Defense. It is down to training, and I like opinions, so Opinions as well.

Im still gonna stay with Dialga, though!

Yeah, but don't forget that they both learn Aura Sphere!

In terms of who id pick for a battle, i would pick palkia. When it came out i got D/P pearl was the first i played and although dialga looks better, palkias got better stats.

Aura sphere is a special move.
Palkia has high special Attack.
Dialga has lower speed but higher attack.
