You are what the League of Assassins call “The Pet.” At first you were just a normal soldier for them. Until they found out that you are couple of so much more. The pain you take is more than the others can handle. You are seem to be loyal and obedient. Only because you never really found the opportunity to escape. Before you became “The Beast” you were sort of a babysitter for Damian. When you weren’t so dull and corrupted, you’d spend time with him, showing him the more humane ways of life. A few years before he went with Bruce you were already gone. Too busy too see him, even he asked about you to his mother. She would always tell him, you are no use for the role of babysitting anymore. That you were gone from him and that he should never mention you again. So now, secretly the League has been sending you off on secret missions and such but sometimes they don’t send you anywhere because you refuse to kill. That time is spent in your cage, where they torture you until you comply. And that roughly takes months. And now you were sent on another mission. To kill a mod boss who went against the League. But unfortunately, when you got to the warehouse. Batman and his entire team/family were there.
