pure luck or by cheating but i wouldnt cheat. it takes the fun out of the game.
out of 16,000,000 rayquaza there is only going to be one shiny. good luck. i only have a shiny koffing on pokemon crystal first try.
Yes every Pokemon can be shiny.
The only way possible, cheats, you cannot get an ordinary raquaza on pearl let alone a shiny one... ^_^
go to the Pokemon shop on mauvile then you can buy shiny cartainer buy it then give it to rayquaza
you can only do it in emerald at battle factory PC look it up on youtube I now have 50 shiny rayquazza
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
anyways its rayquazza no rayquazza does not evolve and does not evolve from anything! hope this helped :}
Rayquazza wasn't made until more than a decade after Pokemon Blue was made.
Dragon/Flying
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
groudor,rayquazza and more
It is Lugia some say it is Dialga or Rayquazza.
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!
