first of all there are four forms of deoxys they are normal, speed, defence, and sp. attack and you are probably wondering how to get them but sadly i don't know sorry.
Update:the forms are Normal, Defense, Attack and Speed. If you want to change deoxys to any of these forms you have to touch one of the four meteorites to the east just outside Pewter City (Heart gold and Soul silver) or one of the four meteorites in Veilstone City (Diamond, Pearl amd Platinum) .
There is one Pokemon with different forms: deoxys- speed, attack, normal, and defense.
you touch one of the meteors in veilstone city with deoxys as your party leader
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.
Deoxys is a legendary Pokemon which has various different forms. To find one in FireRed version, you need to have an Aurora Ticket.
You need Deoxys first of all. Use W.T.W to find the Form Transformers.
Just like any other pokemon, you battle with it. You can change its forms on the route East of Pewter City

Deoxys does not evolve from any Pokémon; it is a unique Pokémon with different forms that can be changed through specific methods. It has four forms: Normal, Attack, Defense, and Speed, which affect its stats and abilities. Deoxys was introduced in Generation III and is known for its extraterrestrial origins.
Deoxys doesn't come from a fossil, and can only be found through events from generation 3 games. If you want Deoxys in Diamond, you will have to migrate one through the pal park after you beat the Pokemon league.
Deoxys...
Deoxys Can't Breed!!
