You can't catch Deoxys on Five Island, you can only get it on Birth Island from a Nintendo Event.
Deoxy IS IN ISLAND 9 AFTER YOU BEAT THE ELITE FOUR
Birth Island, but you will have needed to get the Pass to get there first which is an expired event.
there's no deoxy in Pokemon sapphire, if you want it you must have a friend that playpokemon emerald ,ask him that can you trade a deoxy with him or not.good luck! good luck...that Pokemon is super rare...to catch
no you would have to cheat or trade
i dunno if there are but im 95% sure there isn't. Ppl say u can catch deoxy at mt moon but i dont think so. You can only catch deoxy in emerald i think.
You must get a ticket from a Nintendo Event to go to Birth Island.
nope u have to pass it from the gba games, action replay or gts
i think the only ways are to migrate from emerald ruby or sapphire or action replay
in faraway island you also need a cheat use gameshark email me on jasongalak@gmail.com
After getting the national dex you can find national Pokemon around one island, two island, three island, four island, five island, six island and seven island.
you need the wifi evet item to get deoxy
If you are referring to Staryu, you can catch them in Pallet Town, Vermillion City, One Island, and Five Island by fishing using the Super Rod. Starmie can only be obtained by evolving Staryu.
