Haven't got that far yet but you need to have caught both Groudon and Kyogre (which is only possible if you trade one of them) and then you show them to professor Oak. He will then give you the Jade orb, then you return to where you caught either Groudon or Kyogre and Raquazza will be there!
Migrate raquaza
first, you have to get both Groudon and Kyogre in your party. then, go professor oak and he will give you an orb. go to the embedded tower in the ruins off of Cianwood. Raquaza should be there. ps. Raquaza won't be there if you traded Kyogre or Groudon from Ruby or Sapphire. they have to be from Soulsilver or Heartgold.
It is virtually impossible. (Unless there is some cheat code I don't know of.) You have to get the Blue and Red orbs in Heartgold/Soulsilver. (Trust me. I'm a complete Pokemon Master. And Raquaza is spelled Rayquaza.)
get heartgold beat it get kyogyre and get RAQUAZA
Once you get Groudon, you have to get Kyogre from a Heartgold game and then talk to Professor Oak. The Rayquaza event will happen after that.
You get it at the burnt tower in ecuteak city. However, you must have both groudon and kyogre in ypur party when you talk to professer oak.
After you caught Groudon from the Hidden Tower talk to Mr. Pokemon (First you have to have heartgold to) Youhave to have kygro in heartgold make that person in heartgold trade, And when your soulsilver person has kygro then talk to Mr. pokemon he gives you a green orb and then go back to the hidden tower. go inside and there is rayquaza! You have to have a pokemon higer then lv. 50.
If they weren't in the original gold and silver, they probably won't be in those ones.
raquaza is a master legendary Pokemon in emerald ruby and Sapphire. his is most likely to be the best Pokemon in the series (Case in point)
no
Raquaza isn't in either Pokemon Diamond or Pearl.
yes but u have to get groundon from soulsilver and kyogre from heartgold
