What I don't get about legit pokemon is this:
In the wireless trade corner, people trade starter eggs and such, in the rules it says "no hacked pokemon". So, how do people get chikorita eggs and such like when they have not featured in any of the gba games? surely they would be illegit?
You're right, Chikorita wasn't featured in any of the GBA games, but it was avaliable through both GameCube games [I THINK it was in XD too...]
Or at least, Bayleef was. So don't be afraid to trade for a Johto starter, chances are, it's perfectly legit. :]
Actually Chikorita was featured in R/S/E. Once you finished the Hoenn dex, you'd get a choice of one of the Johto starters to have from Prof. Birch meaning you can get it via a legit method.
Actually, I think, that it is only in Emerald. I've searched and people only say Emerarld.
Oh right, ok that clears up my doubts. But, how do people get loads of Plakias to trade? When people say they are trading rare legendaries, they usually have like three Palkias/Dialgas/Whatevers to give away?
