Seriously, who would win?

They would work together to find both a reason why they exist & a way to bring back Maria

“why do i exist” “because”

Mewtwo: "i sense some emotional dread from inside you" Shadow: "I lost someone special to me a long time ago"

If it’s a battle of the strongest, then Super Shadow, he can freeze time, fly at the speed of light, warp reality, create energy blasts and spears, and he has a gun.

i understand super shadow, but since when can he warp reality? are you talking about the phantom ruby?

Chaos Control can freeze time and warp reality, if the Chaos Emeralds are at their peak then they can warp reality at a Universal level, maybe even at a Multiversal level.

oh.

I recently watched the Death Battle episode. Mewtwo wins
