To get Deoxys in any of the games, you would have needed to go to an event. Unfortunately, these events are already over.
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
There is no deoxys
buy one of eBay
yes with a deoxis
mag pakito ka
202 including Deoxis and Jirachi
If you got the Birth Island event then you can get it.
in a island to get there you need mistery gift
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 have to migrate from a previous game
You'll have to go to Birth Island.
i think you have to have an avent done at gamestop or somewhere for it
