XJ-Sisters



The XJ-Sisters are the protoypes of XJs created by Nora Wakeman. They are also Jenny's sisters.

History
XJ-9 is the ninth robot of the XJ series, but 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 X-J9 was conceived from each of them, she is the oldest in that sense.
