How do you duplicate Pokemon in Pokemon heartgold?

In Platinum you can get the Pokemon ditto and duplicate it cause that's what I did and now I got 3 Palkias!

hey

the guy above is talking crap. using a ditto it is possible to breed different types of Pokemon, either to get the multiple evolutions such as eevee or to get pre evolutions etc. you cant breed legendary Pokemon (which is why idiot above is lying) the only way to duplicate legendary Pokemon is through Action Replay. End Of.

When gamemakers made platinum, they fixed that glitch :O You can't breed legendaries!

You cant :) Goodluck though...
