I would be Palkia go to celesitc town go in the biggest house and talk to the elder she will show you palkia in your pokedex for all 150 good luck
your rival will have one and so will you. A trainer will have the last one.
Palkia, the one on the cover of Pearl.
There already is one in japan Pokemon platinum I don't know when it will come to Canada though.
It is impossable to get one in Pokemon diamond,but there might be one in Pokemon platinom...... hope that helped!
Diamond is not a Pokemon but i think Arceus is one of the strongest Pokemon ever.
There is only one region in Pokemon diamond.
It is not possible to get Mismagius by yourself in Pokemon Diamond. The only way to get a Mismagius in Pokemon Diamond is to trade one from Pokemon Pearl.
Which one?
No you can not have more than one login in Pokemon diamond.
Have two Nintendo DS one have the Pokemon Ranger and one with the Pokemon Diamond. Then go to check egg. Then you have it.
Umm... sorry if this sounds rude, but of course there are Pokemon in Pokemon Diamond! It's one of the Pokemon games!
You should say the Pokemon's numbers, otherwise nobody can tell which Pokemon are the "last two Pokemon". My friend hardly ever battled trainers, so his last Pokemon he had to see were a Wormadam and a Luminion. Actually, I might be taking your question the wrong way. If it will help...wait one second! I just checked my Dex, and it only has 150 pokes in it. No.149 is Dialga, and No.150 is Palkia. I know that in Platinium there are 151 pokes in the pokedex, so you might be thinking of the wrong game. I hope this helped, even though it probably didn't. Sorry. :(
