Sleek, alluring, Jessica's dangerous beauty is yet another "gift" from her father's side, a way to make her a more perfect predator. Her milky white skin never bears the sun's warmth, alabaster and flawless. She is slender but long-limbed, with shapely legs, a narrow waist, and round hips that sway hypnotically with each sinuous movement. Her eyes are a keen, bright blue, like a summer morning, captivating in their piercing gaze. Likewise, her hair is a deep red, like the summer sky at sunset.

Jessica wears tight-fitting clothes that don't restrict her movement. As often as not, her jeans are torn and stained from a day's trials, her athletic tank top stained with dirt and blood (her own or that of the monster she hunted), her perfect body covered in scrapes and bruises that disappear by morning's light.
