Sitting on the opposite side of the reaver, Zero struggled to answer. Was it the killing that motivates him? Not really, life and death was the same for him, the act of killing would not give him any satisfaction. The process, the illusion that separates life and death, that was what he was after...
"The hunt... is what I am after... The chase... the battle. I am part of this equation between life and death. I can not care if my prey is dead or alive after I caught it."
He added, "Besides... I have to eat. All I can do is to fly and fight... nothing else. I have got nothing else... I might as well not exist, otherwise."
