In his vampire form, Diamond is a tall, heavily muscled man with blue-grey skin, black hair, and an ugly face with a white skull tattoo cover it.
In his human form, Diamond is a slender pretty-boy.
Diamond is highly egotistical, with an inflated view of his powers, and a skiewed view of beauty, as he calls his appearance as a hideous vampire pretty, and his pretty-boy human form ugly.
