Not much is notable about the lecherous Ataru Moroboshi, but his extraordinary bad luck sticks out like the horns in an alien's head. When Earth is threatened by a fleet of alien invaders known as the Oni, Ataru is selected to represent humanity in a duel against one of them. It's a stroke of rare luck for Ataru that the duel is in fact a game of tag, and that his opponent is Lum, daughter of the Oni's leader, who places her personal dignity above victory—as Ataru finds out by seizing Lum's bikini top and with it, victory. However, misfortune kicks in again when Lum mistakes Ataru's promise to marry his girlfriend, Shinobu Miyake, as the desire to wed Lum herself, and decides she rather likes the idea. Wielding her influence as an alien princess, she moves in with him. Forced to deal with the consequences of his womanizing ways, Ataru must balance his crumbling relationship with Shinobu while keeping Lum happy, all the while flirting with every woman he meets.

It is the Correct Century, two millennia after a devastating conflict which left the world broken. Earth is now mostly uninhabitable, and thus a remnant of humanity has resided on the Moon while the Earth and its few survivors recover. For years, the "Moonrace," the people of the Moon, have continued to check if Earth is fit for resettlement. A boy named Rolan Cehack and two others are sent down to Earth for a reconnaissance mission. Rolan ends up spending a year on the planet working for the Heim Family, aristocrats living in a Victorian-like society. This family, like others of similar wealthy status, celebrates one's coming of age with a ceremony involving a giant stone statue known as the "White Doll." To Rolan's surprise, the Moonrace suddenly touches down on Earth with the intent of taking it by force. During the attack, the White Doll is broken apart, revealing a mobile suit called the "Turn A Gundam" inside. With Rolan in its cockpit, the Turn A causes a standoff between the forces of Earth and Moon. The young pilot, along with the people of both sides, must keep the peace and avoid another all-out, catastrophic war. [Written by MAL Rewrite]
