Merrick's self-proclaimed "Demon Metamorphosis" causes a purple flame to engulf him, then change him from the weak, skinny, black-haired young Asian boy to a purple-haired, tall, muscular, and quite handsome Asian man. Even his whole outfit will change. The transformation allows him to use a purple fire, gives him a boost of strength, agility, and speed, and heightens a few of his senses, such as his hearing and sight. It also causes an unexplainable rage to "fire" up within him, and gives him an ego boost the size of the sun.
There's a mad man looking at you
and he wants to take your soul.
There's a mad man with a mad plan
and he's dancing at your door.
