Go to Pacifidlog town and surf east a little bit and then go north to Sky Pillar, go in and beat Mach Bike challenge, then use Ultra Balls or Master Ball on Rayquazza.
groudor,rayquazza and more
You beat the Pokemon league and then on the tv it appears that a flying Pokemon appears which is Rayquazza and its level 70 and then you find it on top of the Sky Tower and catch it
Embedded Tower after catching both Kyogre and Groudon there.
You can use a action replay to hack for it or trade it from another game.
you can't soz bro
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.
Rayquazza sits atop the Sky Pillar on Route 131. To capture him, climb to the top of Sky Pillar (a Mach Bike is needed) and save the game. Battle Rayquazza and capture him using a Master ball or many Ultra balls (or even some Timer balls). Rayquazza should then be caught. Good luck!
You can't catch Rayquaza You have to use poketransfer from emerald ruby or sapphire to diamond, pearl, platinum,heart gold, or soul silver and transfer to pokemon black
you don't get rayquazza in Pokemon diamond the only way to get rayquazza is to transfer one from Pokemon ruby Sapphire and Emerald to Pokemon diamond
When you beat the Pokemon league, travel to sky pillar. After that there will be mazes so go to the final door and catch rayquaza
You have to find steven first and the rest of it you 'll know by yourself after finding steven.HOPE THIS WORKS............
anyways its rayquazza no rayquazza does not evolve and does not evolve from anything! hope this helped :}
