Not so sure about Deathstroke

He looks cool, I like some of those moves, will give him a go.

WTF. This looks explosive!

So the according to the reviews, it's a decent fighter on it's own, not just MK with a different skin.
The biggest gripe as far as I can tell, is that humans can fight against super beings, but apparently the story sorts that out, although in a bit cheesy way. I will have to get this at some point.
