You can't. The only ways you can get a DEOXYS in Diamond are you hack, use an action replay or game shark, or you migrate one from Hoenn and catch it in pal park. Good day to you.
No, you can't catch Deoxys on Pokemon Diamond & Pearl unless you have cheats. You can transfer it from your GBA to Pokemon Diamond and Pearl though
No
in Pokemon pearl or diamond, you cannot find a legit deoxys. you can only get one in Pokemon emerald, firered, leaf green by visiting birth island.
action replay
Migrate from emerrald
Not in the wild; you must trade it from FR/LG/E.You can obtain Deoxys in Pokemon Diamond by:CheatingTradingEvent
sadly you can't.
You don't get a Shiny Deoxys from a man. You'll need to get Deoxys in Pokemon FireRed, LeafGreen, or Emerald. It is extremely hard to get a Shiny Deoxys.
No you can't catch deoxys by using cheats
493 including mew deoxys arcues
there is no spaceship area but if you are wanting to change the form of your Deoxys it is at veilstone city . Just have your Deoxys in your party and click a on them. I hoped this helps if you have or will ever have a Deoxys in Pokemon diamond pearl OR platinum :D
What for? I already have one.
