If you have completed the whole game, you well have every Pokemon in your pokedex (Encluding the ones you get after the National Pokedex) and you will have battled everyone and completed the Pokemon Leadge.
You will also have the black Trainers Card.
It depends... What Pokemon is it? (Not that I know...)
You cant get a piplup mask on Pokemon Diamond or Pearl u can get it but i don't know how
Pokemon trainers don't know for sure.
You cant do that in Pokemon pearl or diamond but you can in platinum!! From poke-know-it-all
you mean hipopotas and i dont know
In Pokemon Diamond, I found Articuno in Safari Zone, I just don't know if it works in Pokemon pearl, (Area 1)...
Not that i know of. i dont think there is any.
From what i know you complete Pokemon diamond and pearl by getting all the gym badges, beating the elite four and completing the pokedex. But im not sure if you have to catch all the Pokemon.
there is none. that is what i know from diamond. in pearl, its probably the same. - ho-ohawesomeness
ya you can i have one on pearl!!!!!!!!!!!!!! and i did not get it by trading
Of course there is but I don't know the code. Sorry!
I don't know. But i know how to get 999. You buy a DS cheat cartridge. You then put in Pokemon pearl THEN the cheat cartridge THEN you click on Pokemon pearl/diamond and then click on Pokemon 999 Master balls.
