XJ-9 (Jenny)

Jenny Wakeman was created by her mother, Nora Wakeman, as a 16-year-old teenager created to protect the Earth from threats. But Jenny herself wants to live a normal teenage life and hang out with her friends - Brad, Tuck, and Sheldon. Thanks to her advanced artificial intelligence, Jenny's personality resembles that of an energetic and young tomboy. She strives for a sense of freedom, but also wants to be accepted by her peers. She is generally kind-hearted and enjoys all things teenage, but becomes anxious when her mother or her own responsibilities interfere with her enjoyment. Unfortunately, while she is kind and sweet, she trusts others easily and can be quite naive as a result. Crust's cousins, Brit and Tiff, have often used this to their own advantage or to humiliate Jenny. Despite this, she can also be very rebellious, impulsive, and a bit hot-tempered at times, but always learns from her mistakes. Incidentally, she came up with the name Jenny Wakeman when her relationship with her mother was strained.

In the fight against crime, she is vigilant and determined to see things through to the end, but in very rare cases she can be reckless and hasty. Jenny is designed as a teenager. She is 6.6 feet (1.98 m) tall and weighs around 600 pounds. She has many teal-colored parts, such as her "pigtails" attached with bolts that can act as rocket boosters, her "bangs" and "hair", her "clothes" (a crop top, miniskirt, and boots), and her stomach bolt (simulating her belly button) that holds all of her parts together, as mentioned in the Around the World in Eighty Pieces series. The rest of her shell is white. Her hands have four fingers on each and a hole in the center, and a squiggle in the shape of a neck.
