I have Pkmn Diamond, and im just wondering, how i see all 150 pokemons? Also Palkia, how i see it? Thanks :)?

Question

Yeah. How i see them all? I search someone with Pokemon Pearl and change Leges. and then again back?

Answer 1

Just Battle all the trainers and if u miss one try and buy pearl and trade the ones you cant find and if you can't afford it then find a friend and both of you can get the ones you both cant see.

Answer 2

To see Palkia, you need to talk to an old lady in Celestic Town. She'll show you a picture for your Pokedex.

As for the others, you'll see them if you battle every trainer in the game.
