You need Arceus to get Palkia in SoulSilver.
Go to Ruins of Alph take Arceus with you then go inside all the doors and one of them will make The Sinniohn Champion appear then you will be able to chose between Giratina, Dialga and Plakia.
They will all be a level one.
This only works if you open the wall in the fake/tourist ruin in the Ruins of Alph.
Palkia doesn't evolve according to level in Pokémon Platinum because it's not capable of evolving.
If you want to get it in Diamond, Pearl, or Platinum... It is hidden behind the Dialga/Palkia statue in Enerna City, or the Underground. If you want to get it in Heartgold or Soulsilver... You can get it from the S.S. Aqua captain.
if palkia has low helth then yah because palkia is like all the other Pokemon but there is only one of palkia so try not to faint palkia
After Palkia you get Dialga
It is impossible to get Palkia to have an egg, because Palkia is genderless and cannot be bred.
in the ruins of Alph
Yes
With a Poke Ball
in MT.Mortar
get an arceus and take it to ruins alph
its when you get a dialga palkia or giratina egg
Unfortinutlly you can not legitly catch Palkia in that particular game, you can migrate/trade it from pearl or get it on the GE.
Trade from Pearl or HeartGold/SoulSilver (Arceus event)
nothing, you just have three legendary Pokemon
You can't GET them, you have to trade them from pearl, diamond or platinum.
You use it to get a baby Palkia, Dialga, or Giratina in an event in HeartGold/SoulSilver
You can get a lv1 Palkia, Dialga, or Giratini (Origin forme) through the arceus event.
