After completing the post-game puzzle on Birth Island, the Base Form of Deoxys appears and can be battled. However, the Pokemon you actually catch will be version-specific, with the Attack Form being exclusive to FireRed and the Defense Form exclusive to LeafGreen.

The Base Form itself cannot be obtained in Pokemon FireRed and LeafGreen, even via trading, as it is locked to Pokemon Ruby and Sapphire.

Can You Change Forms?

Form Is Locked to Your Game

Once caught, Deoxys remains in its version-specific form. There’s no in-game way to switch between Attack, Defense, or Base Form, so each save file will only ever have the form tied to that version.
