S01E01 Magnetic Menace
Two musicians working for Umbra use their music to summon a Magnetic Monster on Earth. The Orbots must unite to stop it before it destroys the planet.
Deciding that Mighty Orbots is too powerful for his agents to defeat, Umbra has his agent Metanllis, who has the power to control minds, lure them to the planet Evilon with a stolen defense satellite. There, its prehistoric monsters will surely destroy the robot heroes. Meanwhile, a giant meteor is flying toward Earth, which will be devastated with both the defense satellite and Mighty Orbots unable to stop it!
Earth: the 23rd century. A time of robots and aliens. And of destruction and terror! Can the Galactic Patrol, defender of the United Planets, stop the evil computer Umbra? You bet they can!
