Wow..something VERY wierd..

I think the creators intended to do that.Maybe when Deoxys changes form to defense or attack it's DNA changes.

Well this may all be true but think of this it may be just a coincidence i mean different types of deoxys would need different stats [1 out of 6]and the fact that there was the original [normal as deoxy55 put it], then one with a defense bias and one with an attack bias means that it just so happens that it turned out with these stats initials.
In the end this is really caused by the fact that defense - D, Orginal - N, Attack -A just so happens to spell DNA.

SAND? That is just wrong.

I think this "DNA" thing is not intended because of the speed form.

 

[Pincushion]

Most likely a coincedence...I doubt they intended it to be that, but its a cool find anyhow!

DNA is actually for: DeoxyriboNucleicAcid
Well Mewtwo's is DNA (more of Genetic) and what does it have to do with Attack, Normal, Defense???!!! It is just a coincidence!
