You have to train latios or latias to level 67 then go to the space centre and talk
to the guy looking out the window.He will say there are 67 launches.He will ask you if you want to travel to the moon say yes and then go up the stairs on the moon
and you will find deoxys
I'm not sure if it is the right answer though.
Another Answer
My friend has a friend who did similar to the above and got a Deoxys on the moon. Apparently, you must catch all the Pokemon in Heonn, then talk to the guy in the space station and say you want to go to the moon. Then, whilst up on the moon you can find Deoxys. He is level 70 so bring strong Pokemon with you like Raquaza, Groundon/Kyorge or both, Regice, Regirock, Registeel so on so forth.
It Is Illegal!!
U can get deoxys in the starting of the game if u want..but u need to get ur game evented..or use cheats..without that..there is no way of getting deoxys..!
No you cannot. Only in Ruby,Sapphire,Firered,leafgreen,Emerald,
I found a Pokemon website called Serebii.net, and I also found out that in Ruby and Sapphire. You have to trade from Fire Red, Leaf Green, or Emerald to get Deoxys. So people who post questions about catching Deoxys in Ruby and Sapphire are the real liars. For those of you who posted answers like that. STOP MAKING LIES YOU TWITS!!!:@ :@ :@
deoxys didn't exist until generation three (ruby, sapphire, emerald) so is impossible to get in crystal, which is generation two :)
no
It is rather unfortunate that you can not get Deoxys in Emerald, however, it is possible if you go to a Nintendo Event.
You can't catch Deoxys without having gone to a Nintendo Event (which has been passed for several years now) where you get something that allows you to go to the island where you can catch Deoxys, or without cheating. It's impossible.
Unfortunately the event for Deoxys in the GBA games have passed. There's no way to get it in Sapphire without either trading for it or hacking it.
It Is Illegal!!
In Ruby and Sapphire, you cannot get Deoxys without trading it. In Emerald, FireRed and LeafGreen, you need the Aurora Ticket, which is an event item. The only way to get an Aurora Ticket now is by cheating.
get Pokemon pearler (i don't mean pearl) and you can go up against deoxys in the grass that's how i did it. but i did get the pearler game when i went on holiday.
Sorry, you can't... without cheating. But PLEASE don't try that method.
no you cant find deoxys in sapphire. but u can go to 4shared and download a game called Pokemon sharrowns.in it you can catch most of all legenderies.
Sorry But as much as i would love to catch it, you can't catch in Pokemon sapphire :(
You need to migrate it from FireRed, LeafGreen, or Emerald. But if you have a Deoxys in Pokemon Ruby or Sapphire, then you can migrate from them to Pal Park.
There are sadly no special events to catch Deoxys in Sapphire. You HAVE to trade a Deoxys caught in an event from FireRed, LeafGreen, or Emerald.
