Fan Casting ''The Survivor'' in Injustice: Avenged

In the Mid-Credits Scene for the film, we cut to a tavern located far underground, we see a civilization comprising of the mutants that served Batman's Regime living a life for themselves, before we cut to a dark tunnel in the cave, where one of the mutants is finished conducting surgery. The surgeon then asks the patient, ''What do we do now, Commander?'' to which the patient replies, saying, ''We wait. We wait until I say the time to strike has came. For as long as Kal-El has dominion over the world, The Injustice Wars rage on...'' before he stands up and leaves the cave to greet his new army outside the dark room in the cave.
