In the alternate reality of Kiva's World visited during the journey through the nine worlds, Dogga appears as one of the three loyal servants known as the Armed Monsters who serve the local Kiva. He belongs to the Franken Race, a tribe of powerful beings, and is noted as being the last surviving member of his kind in this world as well. In this reality, Dogga continues to fulfill his primary function as a weapon for Kiva, responding to a special whistle call by transforming into the Demon Iron Hammer known as the Dogga Hammer, a massive fist-like war hammer that allows Kiva to switch into his powerful Dogga Form. His role in the story is closely tied to his master, the Fangire King of this world, a young man named Wataru. Unlike a typical monster, Dogga and his fellow Armed Monsters, Garulu and Basshaa, act as steadfast allies and guardians to their King. When a powerful Beetle Fangire defeats Wataru and declares himself the new King, he proceeds to dissolve the existing truce between humans and Fangires. As Dogga and the others question the legitimacy of this new ruler and his intentions, they are forcibly absorbed into the Beetle Fangire's armor, becoming power sources integrated into his breastplate and shoulder armor to fuel his own transformed state, the DoGaBaKi Form. Within the narrative of Kiva's World, Dogga does not possess a distinct separate personality, largely serving as a silent but powerful entity defined by his immense physical strength. His primary motivation is inherent to his nature as an Armed Monster: to serve the true King of the Fangires and provide his power to fight against their enemies. The character is depicted as having no special magical or energy-based abilities outside of his raw physical power, which far exceeds that of ordinary monsters. His attacks are devastatingly straightforward, and his transformed hammer state can call upon lightning, store its energy, and unleash a finishing attack known as the Dogga Thunder Slap, which manifests a giant energy duplicate of the hammer head to crush opponents.
