You will need to migrate from Pokemon Ruby/Sapphire/Emerald.
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 get Rayquaza on Pokemon Pearl. You have to MIGRATE it
Migrate it.
you cant find rayquaza on diamond or pearl its from Emreld
there are 150 kinds of Pokemon that you can see and/or obtain. Unless you have friend trade you Pokemon that you can only get in pearl to you, you'll never obtain them all. In Pokemon diamond and pearl all you have to do is see the Pokemon and you get its data unlike the older versions where you have to obtain them.
darkrai and arcus
you can not get rayquaza in dimond, pearl, platinum, black, and wite. you can get it in gold, silver, heart gold, soulsilver and emereld
Milktank is located in route 209 and 210 in both Diamond and Pearl.
You actually cant physically catch a rayquazza in diamond or pearl. If you have diamond or pearl and you want a rayquazza you need to get pokemon emerald capture it on there and then migrate it onto your peral or diamond game. Cheers boiz and gyrls.
No, you do not need diamond and pearl to obtain all the Pokemon in the national pokedex. You either need to have a friend who has all the older Pokemon, or you could transfer the Pokemon yourself from older games.
IT IS NOT IN POKEMON DIAMOND OR PEARL BECAUSE IT IS ONE OF THE STARTING POKEMON IN LEAFGREEN!!!!! Migrate one from firered or leafgreen.
No sadly there is no way to catch Rayquaza in Pokemon pearl diamond or platinum except use action replay, migrate it of your gba (if you have it) or use the world trade center thingy in jublife (if you have internet)
