No weapons: Shadow attempts to use Chaos Control to slow down time for Mewtwo, but Mewtwo's psychic abilities prevent this from happening, in all likelihood. Mewtwo wouldn't be able to hit Shadow with an attack either, because Shadow can run at 600 mph as well as use Chaos Control to teleport himself. Tie.
Weapons: Mewtwo has no weapons to use. Shadow uses the Chaos Emeralds to go super. Shadow wins.
mewtwo can lean focas blast mewtwo would win
Mewtwo can control the minds of others mewtwo would win,and mewtwo would probably clone goku and make an army of goku's!!!!!!!!!! that is if he was a poke'mon.
they are strong characters in the game but silver and shadow are the same strength so one time shadow will win and another silver would win BTW shadow dies :(
Mewtwo would most likely win due to Ho-oh's low special defense stat.

There is no such Pokemon as "Shadow" mewtwo. There is a regular mewtwo that you can catch like any other Pokemon. It's located in the Cerulean Caves.

It really depends upon how much they are trained and which moves they know. Mewtwo is stronger but Mew is more skilled. Presumably, if Mewtwo calmed down a bit and trained more, Mewtwo would have the advantage.
