Zenon

Zenon Kar is a trouble-prone 13-year-old girl who lives on a space station with her family in the year 2049 AD. When she runs afoul of the station's owner, Parker Windom, she is judged to be "incorrigible" and punished by being exiled to the worst place imaginable: the planet Earth. After several painful weeks of adjustment to her new surroundings, Zenon enlists the aid of her earthbound pals to return to her "real" home with evidence that the "respectable" Mr. Windom is up to no good.

In 2015, Zenon Kar is 2 years older but no wiser about the dangers of meddling, but when she shows Nebula how to play a new game, she inadvertently empties out Commander Plank's office and is assigned work detail in the Alien Patrol lab. Worse: the space station is now under command of the military, and General Hammond is assigned to command the station and boots Commander Plank out of his office. Even worse: he assigns Zenon to look after his daughter, who turns out to be her demanding old nemesis Margie, who threatens to have her dad kick Zenon and her family off the space station if Zenon doesn't obey her. Zenon then discovers that her space station is being decommissioned due to damage from Windom and Lutz's plot, so she sneaks down to Earth to try to stop it after she gets a message from aliens who seem to want to meet with Proto Zoa. Margie wants to go too, so she sneaks down to Earth as well but makes it look like Zenon forced her to go with her. With Aunt Judy's help, the girls track down Proto Zoa, who has gone into hiding during a dry spell, and convince him to join them. With Margie, Aunt Judy, Nebula, Orion (the Alien Patrol lab guy), Proto Zoa, and her mom, Zenon goes to meet with the aliens near the moon. Unfortunately, their ship runs out of fuel and they nearly crash to their deaths on the moon, but the aliens show up and rescue them. They turn out to be friendly; communicating with Zenon telepathically, they reveal that they've been lost on space for 3 years and need the ship's navigation charts to get home--just taking them would be rude. When they have the charts they tow the ship back to the space station, where General Hammond refuses to relent, saying the space station is too badly damaged and must be destroyed. Margie stands up to him for once, but it isn't enough until the aliens return and repair the space station as a thank-you gift for helping them. With the space station saved, Commander Plank and General Hammond are assigned to command it together, Aunt Judy marries Plank, and Proto Zoa plays at their wedding, dedicating his new song to Zenon, having been revitalized by the whole experience. The aliens had actually been trying to communicate with Zenon, not Proto Zoa, using the transmission of his old concert to do so. Margie convinces her dad to let her stay, she and Zenon become friends, and attraction builds between Zenon and Orion.

In the third installment of the hit Zenon trilogy, it's 2054 and Zenon Kar is 17 and competing to win the Galactic Teen Supreme contest--against handsome competitor Bronley Hale--and celebrate at the Moonstock Festival. She also reunites with Moon preservation activist Sage Borealis, who is desperate to keep the Moon from being colonized and exploited and wants Zenon's help. Meanwhile, Commander Edward Plank and Aunt Judy Cling's new foster daughter Dasha is starstruck by Zenon and finds staying out of trouble difficult. During the last competition for the Galactic Teen Supreme contest, moon goddess Selene appears and threatens to destroy the Earth, and Zenon must save everyone from this angry deity. It's up to Zenon to save everyone from this angry deity. In the end, Zenon, Sage, Bronley, and Dasha and her friends Margie and Cassie team up to evacuate everyone in Protozoa's tour bus and try to remove the Moon Dome, with each taking a hover pod. Unfortunately, the dome is too heavy until Commander Plank and Aunt Judy show up looking for Dasha. They're able to help lift the dome and send it drifting into space. Selene then destroys the rest of the base and waves goodbye as the friends return to Earth. Selene stops the wild weather she caused, Zenon and Sage kiss, and Protozoa's band Microbe and the new hit band Cosmic Blush hold a concert.
