who wins? not just in terms of a battle, but in terms of coolness factor as well? my vote goes to the original uber, 'two. cause he rocks. here is my set for him:

T-bolt
psychic
recover
brick break

all my bases covered. he holds an amulet coin, cause i just use him to beat the whole league and get $$$.

i voted for deoxys cuz there are only a fer pokemon that could change forms and i find that cool and he wuz the first to do so

deoxys gets my vote because of it's attack form. THAT is cool. and it's speed form, defence form. "it's all good baby". Plus, with zap cannon and a few other attacks: cosmic power, counter, Psycho boost, recover, It's set for life.

Deoxys. Attack Form+Extremespeed=Ownage.

Deoxys can change forms.

I also think Deoxys would win in a battle - Choice Specs Shadow Ball hurts.

BTW KOL40, not to criticize, but you may want Ice Beam or Calm Mind on there, over Psychic. Psychic is not the best Uber attack type, because so many pokemon are resistant.
EDIT: that's assuming it's for the uber metagame

I voted Deoxys, his speed form is awesome! I also think, due to his different forms, he is more interesting battlewise.

yeah, D's forms are pretty cool, i like the one where he is big and has 2 thick club arms (i think Def.). anyone know what form he takes in PD?

Whew, hard choice. is more popular, but he learns psychic at high level. I choose .

Mewtwo definitely - Deoxys can't take a hit to save his life. Plus, Mewtwo is faster, and thus would have the edge. Combine that with a huge movepool, and you have something that wimpy form-change boy can't handle.
Something like Aura Sphere/Shadow Ball/Psychic/Recover with Wise Glasses could take down Deoxys pretty fast. (My moveset has T-Bolt instead of Shadow Ball, but then Mewtwo can't get a 2x hit on Deoxys.)

And can Mewtwo take a Shadow Ball from 180 base SpA Deoxys, with max SpA and Choice Specs/Life Orb

BTW, Deoxys has 150 base Spd, Mewtwo has 130. So Deoxys is faster.

With Mewtwo having base 90 SD, I shall enjoy testing your theory. And wth how is that stupid thing faster than the ultimate fighting machine. Now Deoxys is no longer my second favorite Pokemon.

- DNA
(We only use Ghost type moves to take down Psychics cus all the Dark special moves suck...why is that...)

is way cool than

meh forget my last post it is cool and all to change forms but rele now i think bout it deoxys replaced mewtwo in my heart
