Pokemon Platinum because you can catch more legendaries!
I have one in Pokemon platinum one in Pokemon diamond and one in Pokemon crystal
No, Bibarel's are one of the worst wild pokemon there are in pokemon platinum pearl or diamond
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.
You should use it on one of the 'roaming' pokemon, like Cresselia in Diamond/Pearl/Platinum.
You will have to trade to get one. It is only available in Pokemon Diamond.
No. You would have to get one from a friend with diamond or pearl.
You will have to trade it from Diamond, Pearl or Platinum to get one.
you can get one in Pokemon Platinum or in Pokemon Pearl then trade it to diamond
In Diamond and Pearl, you can find one in the Honey tree near Valley Windworks. As for Platinum, I don't have it.
you will have to transfer one from Pokemon diamond, pearl,platinum,soulsilver,and heartgold
For Pokemon platinum, you have to beat the game, then get an adamant orb from Pokemon diamond. It's at level 70. For Pokemon diamond, it's part of the story. For Pokemon pearl, you have to get one from diamond.
Well this is one way you will need two Nintendo ds's and a platinm and diamond or pearl or platinum, just get a starter Pokemon in diamond in pearl or diamond and trade it into platinum, repeat this until you have all starters! If you have an action replay though, You can go to trainers who have the Pokemon, battle them, then capture their Pokemon!
