well, i have a theory that you can catch rayquazai when you lower the pp for his moves. just caught rayquaza on ruby and i was using zapdos, metwo and articuno who all have the special ability that reduces pp for moves quicker. he had run out of pp for extremespeed and fly when i caught him and had low pp for his other two moves as well. think about it, if he has no pp left he cant battle you so maybe they made it so he becomes easy to catch the less pp he has for his moves. so it could work, im not sure, just an idea. might as well try it.
you continue catching the legendaries if you haven't already got them.
Go catch some other pokemons Try catching Rayquaza.
You own every trainer you meet! :)
The trick is to save your master ball.
That depends on what you have done before. Nothing special happens after you catch rayquaza. If you haven't done it yet, you can catch Latios/Latias.
You have to go to prof oak he will send u somewhere :)
In SoulSilver, you can find Rayquaza in the Embedded Tower if you have possession of the Jade Orb. EDIT: you can only get the jade orb from catching groudon and Kyogre. ~Riack~:p
Try and trade a Kyorge with a Pokemon and go to the place where you get the orb and go back to get Rayquaza.
No, there is no such thing as a 'Cheese Orb'. However, there are three orbs: the Red Orb (for catching Groudon in Soul Silver), the Blue Orb (for catching Kyogre in Heart Gold), and the Green Orb (for catching Rayquaza in both games).
Well, try beating the 8th gym and the elite four. I recommend Visiting and area near Pacifidlog town called sky pillar and catching Rayquaza at level 70.
You beat rayquaza. After that the game is tecnically over but there is a lot of stuff to do like catching all the legendarys and all of that stuff.
yes by pressing and holding 'A' when the poke ball opens
