NO
i reckon PLatinum. it has all the new features but doesnt allow some Pokemon to appear in the wild that do in Diamond/ pearl. but platinum also has even rarer Pokemon that don't appear in pearl/diamond. I have all three. YAY
No, Rotom is a Generation IV Pokemon (Diamond/Pearl/Platinum) and does not appear in the earlier games.
I think you're thinking of Looker, the police agent that continuously shows up in Platinum. Unfortunately, he doesn't appear in either Diamond or Pearl; only Platinum.
For most routes, the pokemon be the same. But a couple of routes will be different compared to diamond/pearl.
if it is Friday on your ds clock it will appear in velley windworks does the same thing in diamond and platinum
You can't find Palkia in Pokemon Diamond, but you can in Pokemon Platinum. After you catch Giratina, go back to Spear Pillar, and one of the two legendaries should appear. After you catch the first one, go back again to get the other one.
It is for transferring Pokemon from the GBA games to diamond/pearl/platinum. They will appear in the grass and you have to catch them with Pal Park Balls
Yes you can get Arceus if you have a Pokemon platinum,diamond,or pearl and you have giratina dialga and palkia trade them to your Soulsilver and then a mountain will appear somewhere and then Arceus will be in there
Turtwig does not appear in Pokemon Sapphire, or in Hoenn for that matter. Instead, you can find Turtwig in Generation IV (Diamond, Pearl, or Platinum).
Groudon does not appear naturally within the game. Transfer it from Diamond pearl platinum soulsilver or heartgold.
The ones that are exclusive to only pearl and platinum. The Pokemon include croagunk, glamor and purugly, and I think there's another one too
If you are asking as to why they are not there, it is because you probably haven't defeated Team Galactic on top of Mt. Coronet, they will appear at the lakes after you do. *this is for Pokemon pearl, diamond, or platinum*
