(Covers information from Anderson's universe)
Pock Mark was the most frightening of a group of survivors outside Salt Lake City. He had a large mohawk and a blue jacket with blue jeans and a T-shirt with handwriting on it.
He, like Rancid, didn't use any of Alice's weapons against her, he used his own revolver. Pock Mark single-handedly opened the cages and let the Cerberus out to attack Alice.
