your right.. it's actually the secret character michael jackson in his alternate outfit.. lol it's sub-zero.. i bet the medallion gives him power but drains him.. also he could be the deceptor.. in da he put on the act for raiden.. said he was good.. but maybe he's changed.. the medallion gives him power but he's begone to go insane with the power..

I'm suprised

my guess is that they either brought in a new Sub to replace the one from MK:DA since people was complaining he looked too old or MK:D isn't a true sequel to MK:DA...only speculations though, i can't really see how else to explain it.
