Deoxys: After you get the Aurora Ticket use the ferry in Vermilion City to Birth Island, also known as Nine Island. Then you go through a puzzle which finally leads you to the DNA Pokemon Deoxys!! I have 2. Before you go to Birth Island stock up some ultra balls or a Masterball, because it's not going to be easy to catch him. And bring level 70s or he'll thump your precious Pokemon!!
You need a Secret Slab or Mystery Part, I believe. Deoxys appears on the 5th, 6th, and 7th floors of Temporal Spire, in Speed, Defense, and Attack Formes, respectively. In order to recruit Deoxys, however, it needs to be in its Normal Forme, which can be found on the 17th floor of Shimmer Hill. Keep in mind that even if the conditions for Deoxys appearing are met, it may not appear every time you go there.
its kinda complcated. first it can only happen MIDNIGHT on MONDAYS(i changer my time on my ds to midnight so i did it around 3 in real time (:) you got to mt.moon and go to the small square lake. when you get there a group of clefairy will be dancing around the lake. they will dance for about 30 second and the one will see you and tell the rest and then they will run but one will drop a moon stone. pick it up. then in the lake a reflection of the moon will be on it. surf out to the middle and the battle should start.
Once again rookies there's no deoxy's in this game unless you trade it to your game!!
You can't really get Deoxys in Pokemon Ruby and Sapphire the only way to get it into your game is to transfer it from Firered and Leafgreen and Deoxys is located in Birth Island in Firered and Leafgreen.

No. Deoxys did not exist until third generation of Pokemon. Third generation consisted of the games Ruby, Sapphire, Emerald, FireRed, and LeafGreen. Entei, Raikou, Suicune, Ho-Oh, and Lugia were available in the Pokemon Crystal game.
you can only get it by using a game shark and get a ticket to go to the moon then look around and then randomly he will pop up
Leaf Green is the Gameboy Advance game that goes with FireRed. Insert it in the bottom of your DS to get extra Pokemon, such as Vulpix.
