Guess who this is. It's Eyeless Jack!
I see Eyeless Jack as sorta like Boris the Animal from Men in Black 3, what with his uncanny valley human disguise and his gnarly physiology.
*Because Injustice: Gods Among Us is a DC Comics game, his bio puts up an implication that he's thought up to be a metahuman.
*Murmur, for those who don't know, is a Flash villain and though he's not a recognizable as the rest of his rogues, he is part of the Rogues regardless. He's a former doctor turned serial killer who wears a mask and kills people.
