Raiden seems overdone. Scorpion was a little underdone I think.
No, just a wraith resurrected by one.
Except for Sonya, I don't really see what's so wrong with the rest of the characters.
There's nothing wrong with how Scorpion looks, but the "EXTREME DEMON BLOOD!" thing in his bio is stupid. Raidens clothing and hat are both ridiculous. And since when is Kano half terminator? It's trying way too hard to be serious and gritty, two things that MK is totally not. It's cartoonish, and full of violence that's like a gory 3 Stooges, not "WE ARE ALL SO DARK AND TORTURED! OH GOD, LOOK AT ALL THE SPIKES ON MY GLOVE! I'M FIGHTING IN MY PANTIES!!!!"
