if you mean once you have one, to get more of the same one, you can do a few things. first you can breed them with a ditto, (if you use this method, you won't be able to breed a ditto, or a legendary) second you can use the duplication cheat in action replay (you can Google this one) I hope I have been of help, good luck
To multiply items on Pokemon Diamond/Pearl, you need the action replay. Unfortunately, if you have the DSi, the action replay won't work. It only works for the DS. If you want to 'multiply' Pokemon, breed them by leaving a male and female Pokemon in Solocean Town Daycare Center. Possibly, they could lay an egg!
do you mean reproduce you can do that by giving your Pokemon with a ditto to the day care......
