I thought about this kind of discussion, but I don't recall seeing anything like this before. Correct me if I'm wrong if there was a thread like this before.

My Deoxys is almost as powerful, even more, than my Mewtwo! But I don't know who would win in a battle. (If Mewtwo was a lower level as Deoxys. Or if Deoxys had higher stats...)

My Deoxys is at Lv40, and has NOT been trained with a Macho Brace before. It is totally unbeatable against my other Pokemon. Their stats are nothing compared to its raw power!

But, compared to my current Mewtwo, it's almost as strong (if Mewtwo were at Lv40). My Mewtwo is at Lv100, and it's on my Ruby as well. I sharked an egg as a Mewtwo (just like one of my friends did), and raised it from Lv5 to Lv100. This Mewtwo of mine has a ultimately, raw brute strength. It has been trained with a Macho Brace 100% fully. I got the egg and hatched it on Sapphire, and traded Mewtwo to Ruby.

It's strength is this:

Mewtwo, Lv100
Nature: Quirky
ABILITY: Pressure
HP: 386
ATTACK: 363
DEFENSE: 250
SP. ATK.: 416
SP. DEF.: 253
SPEED: 382
MOVES: (adapted from Pokemon Stadium, except for Rest)
Thunderbolt
Psychic
Blizzard
Recover

Here's Deoxys, so far:

Deoxys, Lv40
Nature: Relaxed
ABILITY: Pressure
HP: 101
ATTACK: 145
DEFENSE: 68
SP. ATK.: 136
SP. DEF.: 50
SPEED: 130
MOVES: (vs.: Dark and Ghost)
Shadow Ball
Psychic
Brick Break
Cosmic Power

What do you think is more powerful? Will my Deoxys become just as powerful?

This is also a discussion. Think which is more powerful yourself.
