Kurobon, also called Black Bomber, stands as a prominent figure within the narrative. He operates as the "lone wolf" among the primary group of protagonists, maintaining a serious and grim demeanor distinct from his teammates. Preferring solitude, Kurobon typically intervenes during critical moments to aid his allies before departing promptly. This pattern results in comparatively fewer appearances throughout the storyline.

Kurobon demonstrates advanced age and superior combat proficiency relative to his companions. His capabilities encompass martial arts expertise, exceptional agility enabling wall-leaping maneuvers, and remarkable speed. A calm and strategic mindset allows for effective contingency planning and crisis aversion. Technical aptitude extends to proficient mecha piloting and mechanical reconstruction of damaged battle equipment. While outwardly stern, he possesses underlying compassion and concern for associates.

Genealogical connections identify Kurobon as the grandson of scientific authority Dr. Graybon. He maintains fraternal ties as the older twin brother of Jack, who later emerges as the antagonist Dark Prince. This familial relationship positions them on opposing factions during the conflict. Their divergent paths create narrative tension, particularly during confrontations.

In combat, Kurobon employs specialized mechanized armor known as B-Da Armors. The initial Black Gattlinger suit featured gatling-style projectile capabilities but proved vulnerable against high-level adversaries, ultimately destroyed fighting the Hogane Dragon. Subsequent upgrades included the capsule-cockpit equipped Black Cluster, later succeeded by the dragon-transformable Black Devaster featuring dual-barrel firepower. This final iteration could combine with other units to form the ultimate Saint Dragon configuration during decisive confrontations.

Kurobon maintains a companion B-Daron named Hiryu, a creature that facilitates essential power activation for combating antagonistic forces. During the Bakugaiden V storyline, he operates as an elite B-da Cop, earning recognition as the "uncrowned king" through accumulation of shining medals. His operational methodology persists, involving timely interventions during critical situations followed by immediate withdrawal.

Personal preferences include consumption of caffeinated beverages such as coffee and cream soda, as documented in supplementary media materials. This detail offers minor characterization depth beyond primary narrative functions.
