Jenny Wakeman (XJ-9)

Jenny is in her room doing research and training her new combat skills.

Jenny was designed as a teenager around 16 years old (in design and mindset), but it had been 5 years since she had been created, prior to the events of I Was a Preschool Dropout (2002). As her number indicates, she had eight prototypes, which she treats like her older sisters.

Although she was designed as a teenage robot, presumably with the adolescent mind of a 16-year-old girl or older, she apparently went through a period of childhood according to the episode Humiliation 101 (2004). As revealed in the same episode, she also spent some of her early years as a crude steam-powered robot before being upgraded to a hydronium-electric power hybrid (as seen in her Master Plan blueprints).

For an uncertain period of time, she was prevented from leaving the house by her mother except for the purpose of saving the Earth, where she would not be seen by the general population. After the events of It Came From Next Door (2002), she was finally able to interact with the outside world and make human friends, namely Brad Carbunkle and his younger brother Tuck, and later enrolled at Tremorton High School, where she soon met and befriended Sheldon Lee.
