Harriet is a dark-skinned young woman with platinum blonde and brown hair shaved on the sides and violet eyes.
She wears a very short-sleeved Atlesian Specialist uniform that consists of a sleeveless white vest, a rolled-up blue shirt, a red tie and white shorts. There are also dark blue strips connecting from the sides of vest down to the silver greaves on her knees, exposing the inner part of the thighs and the back of her calves. She also wears blue fingerless gloves and silver shoes. The blond portions of her hair rest in a pattern that resembles a rabbit's ears.
Harriet is competitive and quick-witted in nature.
