Ahem... these types of threads shouldn't be happening if I wasn't so lazy with continously delaying myself from updating the FRLG FAQ guide with Shadow... anyway here's part of the what should have been upgraded guide (it's still in development)
Deoxys and Its 3 Forms
(guide by Demonchaos916)
Deoxys is a genderless, Psychic type Pokemon that cannot breed and has 3 different forms(Offensive, Defensive, and Balanced) which will be explained later on. Right now in the U.S.A., Deoxys can only be obtained through using a cheating device. Until Pokemon versions FireRed(FR) and LeafGreen(LG) is released in America (or if NoA holds a special event before the release), that is the ONLY way to obtain Deoxys. Anything you heard, ranging from capturing all 200 Pokemon, getting 5 Trainer Stars, to flying to the moon, is a rumor and a lie.
In FR/LG, you can get Deoxys through the use of an Aurora Ticket to reach Island 9, which is what people are calling the island until an English name is given. The Aurora Ticket was given out through an Nintendo event, which will probably also take place in America once Fr/LG is released. You can still also just use cheats to get Deoxys like most people.
For those of you who own Deoxys in Ruby/Sapphire, you might've noticed you can only have the R/S form (Balanced) of Deoxys and not the other 2 forms. That is because Deoxys' looks, icons, and stats change depending on which version it is in. So if you traded the Deoxys you own in R/S to a FR/LG cartridge, it would change forms depending on which version it is traded into. Deoxys has more offensive stats in FR and more defensive stats in LG. It's stats are more balanced in R/S.
Here is Deoxys' base stats for all three forms. I ahve also listed for each stat's maximum with a personality, in order from left to right, that decreases it by 10%, does nothing to it, and increases it by 10%.

Just like how Deoxys' stats and looks change from version to version, what it can learn also changes. But it's ability, Pressure, stays the same throughout all of it's forms. Here is what it learns from leveling up, using TMs/HMs (these are from RS as I am not sure what the TMs/HMs in FR/LG are), and through the use of the Move Tutor from FRLG.
