You can't. But there is probably an Action Replay Code for that.
pokesav.org, make your own pokemon! Works with the AR
I don't think you can make your own Pokemon and put them onto the ds, it wouldn't be compatible...
you can put them in a day-care it can have an egg.
pokesav.org has a program that helps you write codes. You can make your own pokemon.
No, you can't make new Pokemon on Pokemon diamond...
mew three is a fake Pokemon and doesnt exist in the Pokemon world... -ok then, thanks:) but is there a code to make your own Pokemon?-
nope but you can on Pokemon platinum
No, you have to either find TMs, or buy TMs.
Shaymin does not evolve in Pokemon Diamond.
You cant!!!!!!!!!!!!!!!!!!!!!!!
No you can not. Unless you draw a picture that the Pokemon game creators like alot and they make it a Pokemon which probobly wont happen. Other wise no sorry.
No, there isn't. You'll need to make your own Pokemon hack and input the Pokemon you have created into the game. It's not possible with just an Action Replay code.
