His Body Made Of Iron, His Heart Of Glass

Anger usually spawns from sorrow. Sorrow usually spawns from the loss of hope. And hope usually spawns from the belief in a hero. The Avatar, at first, takes the trauma and core of someone and gives them their identity. This is a place where no human can lie to their selves. But humans always end up changing. And so shall their avatars. *OC's, non-canon, AU*
