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.
No, Deoxys is only in Emerald, and you need to migrate it to can catch it. As for Celebi and Mew, you need a cheat code for them.
you need a gameshark code
no trade it from emerald ruby or Sapphire
no gameshark code is legit
yes there is
The only way to get a Deoxys in Pokemon Heart Gold is to either trade it from another Pokemon game that has it, or use an action replay code.
you can't catch it with out an action replay. i do not know the code.
yes but you have to catch one at a time
To catch Deoxys (without cheating) you have to get the Aurora Ticket from a Nintendo event. You can then go to Birth Island, where you will find Deoxys. there's a cheat code to get to birth islands ! you have to enable the code and then enter any place like a house or poke center or mart... ok the cheat code to birth islands is E5AC0043 E1C4C8F0 (use game shark)

There is a gameshark code for Pokemon Emerald that lets you battle Deoxys anywhere, I think you find it at www.gameshark.com. Otherwise, you need to go to Birth Island.
you have to have an all Pokemon shiny code from an action replay(different person) Oorr if your playing emerald on your GAMEBOY and NOT computer if you get deoxys WITHOUT hax, it becomes black when you see him. IT DOES NOT BECOME BLACK IF YOU ALREADY HAVE IT. IT ONLY BECOMES BLACK AFTER YOU GET DEOXYS AND IF YOU HAVE NOT CAUGHT HIM, GO CATCH HIM.THANK YOU
