Goro Kanbara, alias Ururu, emerges as the central antagonist in the opening story arc, commanding the resurrected dinosaur forces under the extraterrestrial Dinosaur Satan Gottes of the Black Nebula. Tasked with reclaiming Earth’s surface for his overlord, he orchestrates coordinated assaults on humanity from the dinosaurs’ subterranean empire. His forces consist of evolved dinosaur species, some mutated into hybrid monstrosities for heightened devastation, alongside repurposed kaiju from other Tsuburaya Productions franchises, showcasing his multifaceted warfare strategies.

A Tyrannosaurus-derived warlord, Ururu’s reign culminates in episode 19, though subsequent antagonists continue the conflict. The 2021 spin-off *Dinosaur Great War Izenborg: The Dinosaur Army* further enriches the series’ lore, though Goro Kanbara’s specific role within this expanded narrative remains unrecorded in publicly accessible materials. His background and post-series evolution are not explored in additional official media beyond the original storyline and the aforementioned comic.
