This is a list of characters from the Nickelodeon animated series My Life as a Teenage Robot.
Jennifer "Jenny" Wakeman (XJ-9) (voiced by Janice Kawaye) is the protagonist and the "teenage robot" to which the title refers, a state-of-the-art sentient gynoid automaton daughter created by Dr. Noreen Wakeman five years prior to the series. Though XJ-9 was designed to be Earth's protector, armed to the teeth with a wide range of weapons, devices, and transformations, she desires to live the life of a normal teenager and often makes this desire quite apparent to her friends and creator.
Jenny's personality is often kind, friendly and optimistic, though this also comes with being rather naive as to her surroundings. Often, people like the Crust Cousins and Vexus take advantage of Jenny's friendliness to further their own goals, though she usually catches on and comes out victorious in the end. Jenny can also be somewhat of a sucker for trends, even when her mechanical designs prevent her from using them, as evidenced when she wanted to pierce her ears at one point despite not having any ears (Ear No Evil). Though capable of human emotions, having human facial expressions and possessing fully functional tear ducts, Jenny does not seem to possess the ability to dream or experience physical sensations; though there were two episode segments where she received those abilities, in the case of the sense of touch it caused more harm than good and was removed by the end of the episode. She is also able to speak Japanese through a language OS (in actuality it's because her voice actress, Janice Kawaye, is of Japanese descent and can speak near fluent Japanese).
Jenny stands at 6.5 feet (1.98 m) tall (according to her mother, Nora Wakeman in Raggedy Android) and weighs roughly 600 lbs. (revealed by Jenny herself in Historionics). She has blue pigtails, with bolts connecting them to her head, blue hair, white skin, blue "clothes" (a tank top and a miniskirt), a belly bolt (a bolt that simulates a belly button), hands with 4 fingers each and center holes, and a "false nose". Her body processes are carried out by a fully functioning metallic brain, to which her eyes are connected (Mind Over Matter). Her body also contains several access ports for downloading, charging, and other purposes.
