Green Bomber, alias Midoribon, emerges as a minor character in the third series, introduced as a captain stationed on Planet Jupiter. Accidentally infused with Planet Energy Circuit’s power during a clash, he joins forces with White Bomber and allies to establish the Nereid Rebel Alliance, pivotal in overthrowing the Nol Arc Empire and Emperor Dark Bomber.

Promoted to sergeant in later series, he sports military-inspired attire with a bandana and beret. His personality exudes bravery and a competitive edge, often clashing with Black Bomber over tactical decisions, tinged with occasional rivalry. A steadfast bond with Red Bomber underscores mutual loyalty during missions.

He forms a dynamic partnership with Witchy, a spirited young witch who aids him zealously in combat. While Witchy’s admiration occasionally hints at deeper affection, their relationship remains rooted in sibling-like camaraderie. Joint exploits—such as masquerading as ghosts on a derelict ship—blend humor and strategy, though her growing magical prowess sometimes disrupts operations.

His arsenal includes two B-Da Armors: the Grand Greaver, wielding the "Double Metal Shot" attack, and the enhanced Crys Greaver, which unlocks the "Super Metal Double Shot." These armors later unite with others to create the legendary B-Da Calibur, a composite of four hero armors granting supreme combat strength.

Originally a Border Kingdom soldier stranded on an island, his rescue by B-Da Cops fuels his dedication to safeguarding the kingdom against foes like Devil Vader. Aligned with White Bomber and Princess Akabon, he prioritizes Akabon’s safety, even at personal risk.

Evolving from a secondary figure to a central team member, his narrative arc emphasizes adaptability, loyalty, and incremental leadership growth. Interactions with allies and enemies alike weave earnest resolve with moments of levity, reinforcing his role in maintaining cohesion across interconnected storylines.
