Yes
You can't.You can only get to it on Pokemon explorers of time/darkness.But you can still get Dialga on MT.Coronet,by getting its orb and going to the peak of the cliff.You do the same with Palkia.
Palkia and Dialga don't evolve. This is very true. they don't evolve because put together they are the seconed strongest legendary Pokemon you have to get the marine resort to evolve
Giratina created Dialga and Palkia.But still arceus is a little stronger than Dialga but not than Giratina.
I wouldn't consider it a bad thing, just not the best descision. Because there are still many legendary Pokemon that are much harder to catch then Palkia/Dialga. I would have recommended bringing ultra balls instead.
Well it really depends on what you are doing and what moves they have. At the moment I have a level 100 Palkia (Moves- Surf, Spatial Rend, Aura Sphere, Earth Power) that is my favourite and the better due to the fact Dialga's level is 88 and the moves i taught are mostly crap (moves- roar of time, earth power, cut, strength). They both do a good job of smashing other Pokemon. I'll get dialga up to level 100 (teach it some good moves) and vs Palkia. I'll get back to you on this one. Yeah I did this and Palkia SMASHED Dialga. But I think it still doesn't matter because you will rarely be versing hard Pokemon.
Yes. Its basically the same game but with a different format. Like the gyms and the background in battles and also the cities (although they still have the same name.)
you need to capture/kill palkia/dialga at mt cornet and go to team galactic base in veilstone city
If you beat Dialga and Dialga faints, you can no longer catch it.
No, you cannot go to Hoenn in Pokemon SoulSilver, but you can still get the Hoenn legendaries. Pokemon SoulSilver is a copy of Pokemon Silver, and you can only go to Johto and Kanto.
u have 2 go 2 the top of mt. coronet[spear pillar], and battle commander mars and Jupiter then boss. diamond is dialga, pearl is palkia. u can't heal ur Pokemon, so i suggest using a master ball right away if u still have it
He only unblocks you when you either catch Giratina/Dialga/Palkia for Platinum Diamond and Pearl respectively, or beat them in a battle. He won't let you cross until you do so.
it holds dialga still so team galactic could have dialga's power
