The XJ-Sisters are the sisters of Jenny Wakeman when she discovers something downstairs in the basement, she finally realizes she has 8 "sisters," which are actually prototypes. XJ-9 is referred to as the oldest, despite being made last. As the idea of XJ-9 was conceived from each of them, she is the oldest in that sense.
