Intro. Karl has the appearance of a handsome and elegant young Vietnamese man who is between 25 and 30 years old. However, it is actually more than 100 years old. She has long, jet-black hair that reaches her waist, with side bangs that fall past her chin. She wears part of her hair up in a bun held in place with a burgundy ribbon, while the rest falls loose. His eyes are a dark gray that turn crimson red when he becomes enraged. In addition to this traditional hairstyle, she always wears an ultramarine blue Vietnamese aogam. As his alter ego, Phantom, he abandons the traditional hairstyle and lets his hair fall loose. To hide himself further, he wears a mask for a short period of time until Red Shield members discover his identity.
