[quote name='KingBroly']You don't need the National Pokedex, do you?
I already have Regigigas, so...I get another one? I've never seen Shaymin though. I guess if I only need the first Pokedex, I can get 2 of each (since I own D & P)!
Also, they need to release Ho-Oh and Lugia already. And maybe Celebi, too.
EDIT: Wow...Regigigas is level 100.[/quote]
If you have Regigigas already, then you should have the National Dex. But with any concern, yes, you don't "technically" need to have the National Dex to download them.
And as Gwen said, Ho-Oh was available for catch in Pokemon Colosseum, while Lugia was available for catch in Pokemon XD. The funny thing about Celebi is, in Japan, as a pre-order bonus for Pokemon Colosseum, they gave away a special gamecube disc that had Celebi on it, while here in America, we were given the same disc, but it contained Jirachi instead, since Jirachi had never previously been released in the U.S.
I own the Jirachi disc which goes for a good amount on Ebay, and I've tried to obtain the Celebi disc, but the only auctions I've seen for it are for over $300.
