you can not use the pokemons unless you have wifi you can put in offer a realy good Pokemon like lucario or a regi and some one is going to trade the Pokemon you want for the one you put in offer and woala .but you can not have the pokemons from the pokedex.
No.
The Pokemon you see do not go in your pokedex.
you can get a suicune on diamond and pearl by transferring it from a game like fire red and leaf green i think after you beat the E4 and get lots of Pokemon on the pokedex. i hear it's wise to have a master ball because it can flee battle. however you need a certain starter Pokemon. getting suicune, Entei, and Raiku is supposed to differ by choice of starter Pokemon i hear. (I'm currently trying this one out for one of them but it'll take a bit)
go to the vally windworks trade for it or battle someone who has it
AnswerThere is an action replay cheat to fill your pokedex or battle flint in the elite 4
Pokemon number 150 is Palkia, you can get it on the pokedex by trading, battle a friend or seeing the old lady in the library who shows you a picture of Palkia which is then added to your pokedex.
You can't obtain suicune in Pokemon Diamond. You have to migrate it from your Pokemon Firered or Leafgreen. To find suicune in either Firered or Leafgreen you must have the National Dex, and you should have chosen charmander as your starter. Suicune will appear anywhere (except for caves) in Kanto - similar to catching Latias/Latios in Pokemon Ruby and Sapphire.
No, unless you have a National Pokedex you might find a trainer who has one in the Battle Tower.
You have to get the National Pokedex and go past the battle tower and on your way there you will find a cave with Groundon in it.
you can't. You might find one in the battle frontier, but it won't register in your pokedex...
None You just need the NATIONAL POKEDEX!(-:]
you cannot ever beat the battle tower. but if you have completed the sinnoh pokedex then the battle tower will help you complete it. you can battle at the battle tower as long as you want.
