Had to post this as well! "Battle of the Planets! G-Force, 5 incredible young people with superpowers. And watching over them from Center Neptune, 7-Zark-7. Watching, warning against surprise attacks by alien galaxy from beyond space. G-Force, fearless young orphans, protecting Earth's entire galaxy, always by acting as one. Dedicated, inseparable, invincible!"
