You can only get deoxis in earlier versions of Pokemon; emerald ruby sapphire. The event for deoxis ended years agao.
PS: Its April 2009 when wrote
You'll have to go to Birth Island.
you can catch deoxis on the moon you can get to the moon by talking to the scientist he will tell you it has been successful space launch whatever when it reaches 68 or more he will ask you if you want to go to the moon
you can't catch him on saphire. you need to trade it with pearl.
The only way now is to use a gameshark becaus ethe only other way is no longer available which was an event.

you must receive the aoror ticket. The ticket will take you to birth island. when you get to birth island, you go past the sign. there will be a triangle you must then keep walking up to it until deoxis appears. Deoxis at level 30 at the time.
202 including Deoxis and Jirachi
If you got the Birth Island event then you can get it.
You have to transfer it into Pokemon Black or White, or you can also trade for it.
i know how to get nearly every Pokemon without a cheating device. do you know how to get Deoxis on emerald Or is there a way to get Darkrai on diamond without cheats?
you cant you have to transfer it from emerald,sapphire or ruby
