Biography
Lawrence Crock was a thug in Civic City who was in love with Paula Brooks. Paula frequently tried to convince Lawrence to end his criminal behavior to no avail. Paula eventually got pregnant with Lawrence's child, and they married. Their daughter, Artemis, was born shortly after the wedding. Lawrence cut back on his criminal ways, however his past would not go away. He owed money to several crime lords, and eventually had to return to crime in order to pay them off. He was eventually caught, and Paula left him, taking Artemis away from him.

Lawrence would eventually join the League of Shadows and become one of Ra's al Ghul's greatest students. He became a mercenary and used his skills to make a living. At one point he was hired by the Corto Maltesean militia and worked alongside Guillermo Barrera in order to capture several American soldiers to experiment on.

Lawrence became Warren White's head of security upon his departure from Roman Sionis, and secretly manipulated White to do what he wanted. He planned to take vengeance on Civic City and all of the unjust people in it for taking away his daughter.
