Lucifer

A millennia-old greater demon, and the inspiration behind all mythological devils.
"He was a tall man dressed in a black suit. His skin was stark white and his hair was jet black, creating a striking contrast. His right eye was a deep, dark blue and his left was a bright, burning red. His ears were slightly pointed and his cheeks slightly sunken in. He was attractive in his own way, but also terrifying in his serpentine grace."
Lucifer is ruthlessly intelligent, cunning and sly.
