Abby is a tall woman in her early twenties, with dark blonde hair (which she kept braided in a fishtail for most of her youth and early adult life), pale, freckled skin, and blue eyes.[5] While she had a fairly normal build during her time as a Firefly, her thirst for revenge led her to develop a solid and muscular build while a soldier in the WLF, which made her easily identifiable to others.
