i would try the two methods recommended for getting a black charizard on diamond but if you do not have an emerald game or a diamond game then i have no answer
Raquaza isn't in either Pokemon Diamond or Pearl.
You can't get a raquaza in Pokemon Diamond.
he isn't
You need to trade Raquaza's game (Emerald or Ruby) To Fire red. Then go to pal Park.
Migrate it into Pal Park.
when you get to raquaza save then fight him if he is not black restart the game until he is
Impossible without transferring it from your other games. ~Sherry
You can't unless you have an Action Replay Ds
Nowhere, you can't find it in-game.
depending on the game there r certain Pokemon u cannot catch like say on emerald u cant catch palkia or dialga so on diamond u cant catch raquaza sorry
Shiny Rayquaza cannot be caught on Pokémon Diamond unless you cheat.
you can't get the pokemon off of pokemon black on diamond, but you can do it the other way around.
