Professor Hajime Akebono, grandfather of Akira Akebono, is a visionary battle robot engineer who crafted Team Akira’s robotic arsenal. He pioneered the Cluster System, merging Ryugu and Daigu into the formidable Daigunder, embedding discreet authorship stickers within each creation. Early partnerships with Professor Maelstrom (previously Professor Daikun) yielded DragoBurst, DragonFlame, and DragonFreezer—machines that revolted upon uncovering Maelstrom’s plot to weaponize them for global conquest.

Post-betrayal, Hajime independently engineered the Dino Unit (Bonerex, Despector, Trihorn) and Animal Unit (Blion, his inaugural combat robot, Eaglearrow, Drimorg), later incorporated into Team Akira’s forces. Though initially aligned with DragoBurst, the abandoned DragonFlame and DragonFreezer eventually allied with Akira, underscoring Hajime’s lasting impact.

His innovations include Metamorphic Fusion and Armor Fusion systems, enabling hybrid forms like Daigullion (Daigu + Blion) and Daigurex (Daigu + Bonerex). A perpetual traveler, Hajime’s nomadic existence parallels his legacy as a trailblazer in combat robotics, prioritizing adaptive design and tactical prowess. Daigunder stands as his crowning synthesis of strategic flexibility and unbridled strength.
