"Karma sucks. Remember that in the next life."
Andrew has a very unpredictable personality, thanks to his mutation. Most often, he is cool and collected, although the second he enters combat, his cool demeanor leaves, and he becomes a violent fighter.
Andrew was enlisted in the area's National Guard, and was participating in a live-fire exercise when he collapsed. He was rushed to the nearest hospital, and fell victim to the insidious mutation serum. When he woke, he was immediately discharged. The day afterword, he was given medical leave from his Nat. Guard post. That night, he woke next to the torn, bloody body of a person. The man's body was covered in deep cuts, but his wallet was still present. Andrew was covered in the man's blood, and was wearing the tattered rags that were once his Nat. Guard uniform. He reported the death, then requested discharge from the Nat. Guard for "Personal Reasons". His request was granted, and he left town the next day.
