Animal or Human (X-Men)

Sally Alieantha is not a normal human. She is what people call a mutant; her genes being more enhanced then others. She has had a hard past, and the only good is the X-men who have saved her from death. Yet the one thing she is afraid of, the one thing she can't fight, is now coming back on her. The past is coming, bringing the monster out in the Animal. Now she must come in terms with the nature that is in her, from figuring out if she is a human or if she is an animal at heart.
