Jennifer "Jenny" Wakeman (or XJ-9) is the main character of the Nickelodeon animated series My Life as a Teenage Robot. She is a robot with the personality of a teenage girl, created by her strict adopted mother, Dr. Nora Wakeman to protect the planet Earth. However, Jenny desires to live the life of a normal teenager.

In the series' Christmas episode, "A Robot for All Seasons", Jenny agrees to spend Christmas with a miserable little boy named Todd Sweeny. But Todd overrides her primary programming (to protect the Earth) and reprograms her to seek revenge on Tremorton by ruining all of the city's holiday celebrations.
