You do this l+r then select
Rayquaza is #384 in the national pokedex, and it is a Dragon-Flying type Pokemon.
Rayquaza is Pokedex number 384.
you can do a search. the pokedex 3D usually is in the apps.
You finish you Pokedex... it is hard!
You could look for the Pokemon modifier code (for the code to work, you need the national pokedex) then, type in rayquaza's pokedex number in the poketch's calculator, press L or R i think, and voilla, u've got yourself a rayquaza.
you can`t catch rayquaza on Pokemon diamond.But you can migrate it after u gat the national pokedex by smarty guy
you have to migrate from Pokemon emerald or trade in the GTS
number 1 because i saw him in pokedex 3D
The 3D Pokedex is completely free.
Rayquaza is not in Diamond only in the pokedex. You would need to migrate it from a gameboy advanced game.
Your main goal right now is to be completing the National Pokedex.
It most likely will be.
