Kinda wanted to submit this for halloween, as Crane is a very creepy guy and I figured his attire is well suited for the occasion.
This idea was basically a what if scenario, if the infection from Left 4 Dead had crossed over into the world of Batman and hit Gotham City. While the origins of the infection in L4D are rather mysterious, I decided Scarecrow could possibly be the instigator of the virus in this scenario, infecting individuals with a powerful new chemical, spreading insanity, chaos and most of all - fear.
Although this is all just a random idea, I guess his new chemical strain would have severe effects on certain individuals, who in turn go through mutations like the Boomer, Witch, etc.
