Absolutely Kenshi too (imo).
What they did with him for his 3 gameplay variations was pretty awesome.
I wish that he could have gotten more story development in MKX aside from "dead-beat dad," though.
but this time we actually saw him in all his new evilness. its more likely than its ever been. now that they showed us the concept in game they just need the feedback from the fans. but who else can possibly fill shao kahns shoes when it comes to powerful badass final boss status
