Years of political tension and mistrust between the two rival nations of Zafran and Revillia escalate to the point of war. Each nations solution: to gain possession of Decimators, the same ancient robots of war that nearly ended all life on the planet 200 years before. As the war ensues and the leaders of both nations become reluctant to surrender, only the desperate plan of Lean, a young cadet, and Nataruma, a psychically gifted young woman, to alter the timeline of events 200 years before stands the chance between humanity's survival or absolute destruction.

Gohan Son and Piccolo are peacefully playing when they sense a powerful entity approaching Earth. It soon reaches everyone's ears that this entity is in fact a small planet on a deadly collision course with Earth. Gokuu Son and Kuririn attempt to change the small planet's path with a Kamehameha, but the attack fails and the two warriors are blown away. However, after coming very close to Earth's surface, the object changes direction on its own and explodes soon after.

The small planet reveals itself to be a vehicle for what seems to be a castle. A large army emerges out of the structure and declares that the planet is now in possession of Slug, king of the universe. While defending the city against the invaders' attack, Gohan loses his Dragon Ball, allowing Slug to take it. After reading Bulma's mind and stealing her Dragon Radar, Slug commands his army to collect the wish-granting relics. With the Dragon Balls in his possession, he uses them to wish his youth back. Now young, wise, and very powerful, Slug commences world domination.

Years ago, Zong Shuai from the Middle State, Wanyan Zang from the Northern Land, and Wen Taiji from the Southern Territory suffered great loss during their fight for the hegemony of the world. As a result, a 20-year truce was established. Now, with the deal coming to an end, conflicts are brewing in the ostensible peace. In hatred and suspicion, the three families set up their respective Blood Orders, listing the names of the most important people of the hostile families and swearing to hunt them down. A breathtaking war is about to commence.

Ever since they encountered aliens on the moon, humanity's technology has developed by leaps and bounds. Half a century later, even though most have it easy, Robby Yaji and Hacchi Kita cannot seem to catch a break in this advanced society. Robby—a man perpetually struck by misfortune—owes large sums of money to debt collectors due to his poor investments in shady get-rich-quick schemes, and Hacchi finds it difficult to get over the boredom of his mundane life. The two end up on an adventure of a lifetime when loan shark boss Yang sends Hacchi to collect the money Robby owes. Rather than pay up, Robby blasts off into space and heads to Isekandar, a planet that supposedly brings happiness to anyone who visits. Seeing a chance for some much needed excitement, Hacchi tags along with Robby on this journey filled with alien encounters, giant robot battles, and all sorts of troublemaking—all the while avoiding Yang and his cronies who are desperately combing the universe to find them.
