Discord isn't just a creature of chaos, he is chaos. Holding back such lawless magic may just be the end of him.

Big Mac had always had these powers, the power to shift. The power to change who he was in the blink of an eye.

Macintosh's parents always told him that he was special. That no other pony could do what he could do. That he had a gift that he could help many ponies with. But that power didn't help him when he needed it most, and now his parents were dead. Big Mac kept his powers a secret, and withdrew into himself, hardly speaking more than one word at a time. But silence can be as loud as screaming.
