Meh, I can call the MK guys superheroes. I mean, Sub Zero is probably Batman's equal Hand to Hand *and* he's a cryomancer. Scorpion/Shang Tsung/Shao Kahn have the whole magic thing going, and we all know how much Superman hates that.
And so on, most of them would be classified as some sort of Meta-Human in DC, if they were there.
Catwoman is a fucking waste, though.
Also: No Kenshi OR Bo Rai Cho? Fuck that.
