Babarian

The Babarians are large, bipedal reptilian creatures native to Planet Babari in Universe 10. Resembling upright dinosaurs with muscular builds and aggressive temperaments, they exist in a primitive state of constant conflict. Their society, such as it is, consists of warring clans that fight each other relentlessly. Even when observed a thousand years in the future via time travel, the Babarians had developed only marginally, building rudimentary structures but still engaging in the same violence that defined them in earlier eras. They are capable of flight and possess enough physical strength to pose a threat to ordinary beings, though they are negligible by the standards of gods and warriors.

The Babarians' true significance lies not in what they are, but in what they represented to Zamasu. During the "Future" Trunks Saga, Gowasu, the Supreme Kai of Universe 10, brought his apprentice Zamasu to observe the Babarians as a lesson in the development of mortal civilizations. Two Babarians were fighting when they arrived, and Zamasu immediately declared that the species should be destroyed for their inability to be civilized. Gowasu, troubled by this response, used the Time Ring to travel one thousand years into the future, hoping to show Zamasu that even violent species can evolve.

What they found was not reassuring. The Babarians had progressed slightly, forming a small culture, but members of the race were still fighting. When a Babarian clan survivor attacked Gowasu and Zamasu from behind, Zamasu killed the creature with his God Split Cut, slicing it cleanly in half. Gowasu was horrified. For Zamasu, the encounter confirmed everything he already believed: mortals were irredeemable, and the gods had failed by allowing them to exist. This conviction eventually drove Zamasu to steal Goku's body, murder his own master, and launch Project Zero Mortals, an attempt to exterminate all mortal life across every timeline.

The Babarians never knew what they set in motion. A primitive species on a backwater planet in Universe 10, they had no concept of gods, apprentices, or the philosophical debates happening above their heads. Yet their existence, their stubborn violence and inability to evolve beyond it, became the evidence Zamasu used to justify the most ambitious act of genocide in Dragon Ball history. It is a darkly ironic role: the Babarians are too primitive to understand civilization, and that primitiveness triggered a god's decision to end all civilizations everywhere. They remain one of Dragon Ball Super's most effective pieces of worldbuilding, proving that the smallest narrative detail can have multiverse-shaking consequences.
