Deoxys is changed into speed form by trading it to Pokemon emerald or by walking up to a meteorite in veilstone city in Pokemon diamond/pearl and pressing A while it is in your party (first slot).
You can't get all of the forms of deoxs in Pokemon emerald that's what I heard from my freind.You can only get the speed form of deoxs.If this isn't true then I'm very sorry.
No, you cannot. Only if you have an action replay, and have the code to get deoxs. If you get the code go into the grass (in the game) while holding select and you get deoxs.
In which game?
Get the aurora ticket.
Deoxys is Phychic type. It has four forms: Normal, Speed, Attack and Defence, which can all be changed by having it in your party and touching the meteorites in Veilstone City.
In Meteor cave, you can get there after recruiting Lugia
action replay or transfer machine
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.
when you decrease or increase speed you are losing or gaining kinetic energy respectively
Acceleration refers to the rate of change in velocity. It can be in the form of an increase or decrease in speed, or a change in direction.
Go to Veilstone City and interact with 1 of the meteorites there, that'll change Deoxys' form into Attack, Defense, Speed or Normal Forme.
In veilstone city at the east there will be four meteorits that each have the ability to change the form of deoxys that are: (attack form), (defense form), (speed form), (normal form).
