A little idea I had for a new OC. Besides, Vicky told me a while ago that I need more human OC's
I'll try and construct osme kind of backstory for him.
At one time he was a normal human, physically speaking. His brain doesn't produce the chemicals it should, he doesn't experience the emotions regular people do. The only emotions he has period come when he murders and kills, and kill he did, he became an infamous serial killer, frankly not caring who his victims were, but he was caught, put on trial, and given a death sentence.
Demonix, seeing the opportunity for a little experiment, rescued him from the authorities and offered him a chance to continue doing the thing he loves, only with a purpose and some direction. He readily agreed.
He has machines built into his body to pump adrenaline into his body. When activated, they make him not feel pain, they amplify his strength, they keep him from tiring, and they give him berzerker characteristics. He also has an artificial heart so that excess adrenaline doesn't kill him. His armor is lightweight and durable, and the blades on those knives on his belt are made of dark matter; stronger than diamonds and capable of harming Jadow. He is swift, agile, efficient, and deeply skilled at the martial arts. He rarely talks, unless speaking to his master, and he follows Demonix's orders to the end.
I was thinking of naming him Nobody, but that kinda' sux. Any other suggestions?
