Strangely, this is the first MK since MK2 that I have felt comfortable with the 3 in my signature. I will probably take a crack at Ermac at some stage as he was my secondary in MK9
Kano. That means ALL variations because he's so BEAST!!! Most of the time.
Sonya. All variations.
Raiden. Displacer & Thunder God
Kenshi. All variations.
Waiting on Tanya. Wont degrade myself in picking a noob friendly Jason who is a nothing more then a $$$ grab.
Nimble Reptile, royal storm Kitana, possessed Kenshi, and gunslinger Erron. Currently been playing the hell out of possessed Kenshi. Although the weak characters are weak, I find I have more fun playing them as they require more thought to win.
