YMMV / Kamen Rider Build NEW WORLD: Kamen Rider Cross-Z

• Complete Monster: Killbus/Kamen Rider Killbus is the flamboyant king of the Blood Tribe and Evolto's abusive older brother who turned his own people into a faction of intergalactic exterminators to kill everything that exists in the universe, including himself, for fun. Years before the events of the show, Killbus destroyed his own home planet and ordered the rest of the Blood Tribe to begin their campaign of mass genocide to annihilate other civilizations across the universe. Searching for his brother to reclaim the Pandora Box for himself, Killbus massacres a news team and tries to kill him to finally achieve his destructive dream.
