Global Robotic Response Unit XJ9 is just like any other robot designed to defend the planet. She's powerful, confident, clever, brave...oh yeah, and she's gotta be home by 9! Jenny, as XJ9 likes to be called, is spunky, dramatic and prone to major mood swings (sound familiar?). She's also obsessed with pop stars, teen magazines and fitting in with the cool kids. Just like a regular teenager, right? Well, yeah...if regular teenagers were 6 feet tall and made of metal! XJ9's creator (a.k.a. mom) is constantly reminding her of her planetary responsibilities, but Jenny's tired of saving the world and just wants to hang out with her friends. What's a teenage robot to do?
