Just how hardcore is Data?

[MetalHead]

Watching clips from TNG's "The Most Toys" got me thinking.

Just how violent could Data potentially be?

His Android strength is obviously significant considering the way in TNG and in a few of the movies he hurls other humanoids around. I wonder just how hard he could strike something in terms of pounds of force and mph of the impact? I dont think he could be as flexible as a biological being, he's sitll a machine, and components usually don't stretch (thats just pure speculation though). So if was taught martial arts per say, how well would that work for him?

And weapons? Data could probablly fire the fastest (and with the most accuracy) with any kind of weapon, be a sniper from any range really.

But the real question is can he kill? Sure in "The Most Toys" something took over and he decided that the guy was to evil to remain alive, but in general (before his Emotion Chip), could Data Kill? I can't think of any examples. All question.s I know.
