The person above is wrong you get on Fire Red, Leaf Green, Ruby, Sapphire and Emerald. I know this for a fact because there are 4 forms of Dexoys which is on the games. Use can use Mystry Gift to copy the Auroura Ticket(the ticket to get to Birth Island) to any of the games.
truthfully, the person right above me is right, (i think). all i know is that u can go into space and catch him in LG, FR and emerald. and im trying to figure out a few things with this too. cuz i accidently got rid of deoxys in diamond.( i know, ouch.) im going nuts over the ppl i got rid of. deoxys, blazican, flygon, blastoise,ect. (BIG ouch.)im trying to find out how 2 catch latios and latias. in sapphire. latias,(i think is the red one?) is in the wild. (im having crap at finding him) and latios( oh i think u know what color. BLUE!) is in southern island( trying 2 figure out how 2 get there.). that's all i have. sry about getting off topic. but u must admit, sounds kinda ouch and interesting. lol. BYE!

Cheat to get the aurora ticket then go to birth island to capture deoxys.

If you want deoxys in Pokemon sapphire, you need an action replay, or an game shark. Or trade from an emerald game that been to birth island, and has caught deoxys.
Birth Island cannot be accessed, for Deoxys is obtainable at the ending of the Delta Episode after defeating the Elite Four.
The sapphire is on Six Island. You need a Pokemon to use cut on the dotted door of the cave.
In Pokemon Sapphire, Latios can be found in Southern Island.
