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 Deoxys first of all. Use W.T.W to find the Form Transformers.
Im not sure about this but I once went underground and found a fossil with one of those tentacle things that Deoxys had but the wall colapsed before i could get it but i think you need a fossil to get Deoxys.
I know this doesn't help, but you need an AR, or a cheat/glitch that you can get online.
you need a action replay and get the infinity master ball cheat start the game (you also need the pokedex and nationaldex 100% compleat cheat) then take you pokedex to professor Rowen he says its complete then professor oak comes and switches your pokedex with the nationaldex after that look up deoxys in your nationaldex look at its number and minis it from your infinite master balls (you may need paper to do the math) then toss the amount of master balls that equal your math answer then walk in tall grass while holding L button and and once you do that your deoxys will with what ever level Pokemon are in that area. (for level 99 put on those cheats + the level 99 Pokemon cheat and do all that is typed down here and there is your deoxys) There is no way to get a level 100 deoxys with cheat so train your level 99 deoxys until it levels up.
No, as of 2014 there is not a listed cheat to get Deoxys in Pokemon Emerald for Visual Boy Advance. The Deoxys does not evolve into any other type of Pokemon.
you get an action replay and cheat
There was a deoxys event at Gamestop that already passed, so you have to get it from someone who went to the event, get it from someone who did cheat, or if you got it on emerald, you can migrate it to diamond from there.
Use this gameshark cheat code Deoxys 8C5DE8C8A33E9D88 or C5946A0E65BE02B0 or FBC061A9072FC320
you have to get Deoxys through cheat code, action replay, transfer from GBA game, or Nintendo event
