First, you need to fight the 7 Gym(Not the 8th Gym)then travel to route 128. Go to the Seafloor Cavern and you will sea a Submarine. Go up and then beat the aqua team and find the place where Kyogre is. Talk to the leader and he will led out the Red orb power.
Rayquaza is not in Diamond only in the pokedex. You would need to migrate it from a gameboy advanced game.
This means that your Pokemon probably has learned fly. This move is not allowed to be transfered from game to game by migrating. You should take rayquaza to the move deleter and have fly deleted and then you can migrate it to diamond and teach it fly then.
The National Dex number for Dark or Shiny Rayquaza is 384 which is the same number that the regular Rayquaza has.
How the heck should i know?!?!?!?!?!?!?
you must import it for one of the gameboy advance games that has a rayquaza on it. to do this, put the game with rayquaza ( make sure you have 5 other Pokemon) in the gba slot. now beat the game and get the national dex on pearl or diamond. then, go to sandgem and surf to pal park. save and go to the main menu. select import gba Pokemon or whatever its called. now in the PC, select your 6 Pokemon and there you go.
You can only get Rayquaza in Pokemon Diamond by trading it from Ruby, Sapphire, and Emerald. The Rayquaza is a very powerful flying dragon type Pokemon.
You can't find Rayquaza it in pokemon diamond, pearl, and platinum. You just migrate it in Pokemon Emerald, ruby and saphirer
you can't
Rayquaza is not in Diamond only in the pokedex. You would need to migrate it from a gameboy advanced game.

You will need to migrate from Pokemon Ruby/Sapphire/Emerald.
You can trade it from Pokemon Emerald. In Pokemon Emerald, when you find Rayquaza, there is a small chance that it is shiny when you find it. Save the game right before you fight him and keep trying until it turns black. Then catch it and trade it to Pokemon Diamond.
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 transfer it through pal park with Pokemon ruby,sapphire,and emerald.
if you want a rayquaza go to your PC (in Pokemon) before that use the R4 or action replay put hoenn legends
