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.
no
impossible without cheating
You can't without cheating.
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.
It is rather unfortunate that you can not get Deoxys in Emerald, however, it is possible if you go to a Nintendo Event.
i don't know but i heard you get it at stone pillar if you have 8 gym badges.
You can get Bulbasaur by trading from FireRed or LeafGreen. Deoxys and Mew are only available through trading with others and special Nintendo Events.
Sorry, you can't... without cheating. But PLEASE don't try that method.
You can't get it without action replay or any other source of cheating, but I don't really know.
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.
Besides cheating and Nintendo Events, there are no known ways of getting Deoxys.
no deoxys cannot be caught in the game. The only way to get it is by trading from someone who has one, getting deoxys from an event or by using a cheating device such as action replay
