Sorry in R/S/E you cant to change forme you would have to migrate to D/P or Platinum and put it in your party, then press A in front of the Veilstone meteors.
Well, you can't change the asteroids but you can change deoxys's forms by having it in your party and walking up to an asteroid and pressing the action button or by the action button i mean "A".
you touch one of the meteors in veilstone city with deoxys as your party leader
They change deoxys form
The meteorites cannot be broken. they are only used for deoxys. if you have deoxys in your party and press a in front of one it (deoxys) will change formssource(s): game experience
You have to Migrate from Fire Red, Leaf Green or Emerald. Or you can use the Action Replay Modifier Code. Also by touching the Meteorites' at the South East of Veilstone City with Deoxys in your Party you can change Deoxys into 4 new forms. Below are the forms. Top Meteorite- Speed Deoxys Middle Meteorite- Change Back to Normal Deoxys Bottom left Meteorite- Attack Deoxys Bottom Right Meteorite- Defense Deoxys
You cannot find Deoxys in Pokemon HeartGold. Deoxys has to be traded from another game to get into HeartGold. The rocks to the east of Pewter City are used to change Deoxys' forms, but you have to transfer one using Pal Park, first.
use it to change deoxys's form
if u are asking how to change its form then go to veilstone city and go to those rocks but u have to have a deoxys in the party
go to Narcene City Museum and on the left there is a meteor press the A button on your DS it will change Deoxys form
There are meteors in between pewter city and mt.moon that can change deoxys form
Veilstone City.
Go to Pewter City and there are meteorites there. Check it and I think Deoxys will change form. (There are 4 rocks: for each of the 4 forms.)
