No, sadly it doesnt but it does unlock groudon.
Hope this helped!
It is not possible to get a blue orb in Pokemon Soul Silver however, you can transfer Kyogre from Heart Gold to Soul Silver to get the green orb in order to catch Rayquaza.
you can't get it. trust me I've tried it. but you can get the red and jade orb. red for groudon jade for rayquaza
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
You must have a soul silver in order to get a red orb. There is no actual need to get the red orb on the game, just trade the Groudon from the Silver and talk to Oak with both. He'll give you the green orb and you can then get Rayquaza.
You don't need to go anywhere with Rayquaza. You needed Groudon and Kyogre to get the Jade Orb to get Rayquaza, but you don't need Rayquaza for anything, It is just another legendary you can have.
The jade orb makes rayquaza appear in hgss after you get kyogre and groudon go to embbered tower to get rayquaza! I recomed to use dusk or ulta balls! Hope I help!
it is the object to summon rayquaza. take it to the embeded tower in Pokemon heart gold or soul silver
Try to trade for a heartgold Kyogre so you can get the jade orb, and find rayquaza.
Try and trade a Kyorge with a Pokemon and go to the place where you get the orb and go back to get Rayquaza.
You can try to get the other kind of orb which will get you kyogre and after you get kyogre you can go back there and get rayquaza.
if you want to get rayquaza get kyorge from heart gold through trade or get growdon from soul-silver, then go to profeser.oak and he will give you the jade orb then go to embedded tower and rayquaza is there
Once you have a Blue Orb and a Red Orb (From Kyogre and Groudon), take them to Mr. Pokemon and he'll give you a Jade Orb. Go back to Embedded Tower and Rayquaza will appear.
