Standing at 5'2, Aubrey has naturally light blonde hair. She has blue eyes and tanned skin.
Aubrey was naturally loving and affection person before the end of the world. She believed the best in people. After the end of the world, Aubrey became harder. But when she tried to test her cure, she was selfless and used it on herself rather than another. She also shows that the world around her still affects her when her camp is overrun with Zs and she escapes with a bus full of children only to have a Z be on the bus and attack them. Becoming somewhat catatonic after the attack, Aubrey went with the group to the school.
