Go to birth island and push the triangle over and over again. Eventually Deoxys will appear.
You can't.
Unfortunately, you cannot catch Deoxys without the Nintendo Event. This event has been over for a while.
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.
From what I understand, Yes!! I think it's a glitch, but you CAN'T catch deoxys normally in Pokemon FireRed. and in Pokemon ranbow (only in japan,and internet. even on mars
mystery gift
Birth Island, but you will have needed to get the Pass to get there first which is an expired event.
You can't catch Deoxys in the wild or a special place. But if you got it in Pokemon FireRed, LeafGreen, Sapphire, Ruby, or Emerald you can migrate Deoxys in the Pal Park in the Kanto region in Fuchsia City.You cannot obtain Deoxys legitimately in Pokémon SoulSilver. You must take advantage of an Event in Pokémon Emerald, FireRed, or LeafGreen to go to Birth Island using an Aurora Ticket, and catch it there, then use the Pal Park to transfer it to SoulSilver. Alternatively, you can cheat.
DEOXYS!! im pretty sure it disguised as a tree near Navel rock
You can't catch it (well you can but you have to do this poke wifi thing that isn't avalible) or use gameshark
you can get deoxys at birth island
There is no deoxys
You would need to use an Action Replay or transfer it from Pokemon Emerald, FireRed, or LeafGreen, for it is impossible to catch Deoxys in any location in Pokemon Diamond, Pearl, and Platinum.
