Description
Daisaku Kusama is the young protagonist who commands the immense robot known as Giant Robo. His life was shaped by tragedy from a very early age. He is the only son of Dr. Kusama, a brilliant scientist who was forced to build Giant Robo for the criminal organization Big Fire. Daisaku’s mother died not long after his birth, and when he was only six years old, his father was executed by Big Fire. Before his death, Dr. Kusama secretly programmed the robot to respond only to Daisaku’s voice and left his son a special wristwatch containing a radio transmitter, the sole device capable of controlling the machine. This tragic inheritance thrust the young boy into a life of conflict as his father’s dying wish was for Daisaku to use Giant Robo to protect the world and stamp out the evil of Big Fire. By the age of twelve, Daisaku had become a full-fledged member of the International Police Organization, fighting alongside an elite group known as the Experts of Justice.
In terms of personality, Daisaku is a complex figure shaped by the harsh circumstances of his childhood. Having lost his family, he was forced to mature quickly and take on the immense responsibility of controlling the world’s most powerful robot. Despite this burden, he retains a degree of childish wonder, optimism, and a sometimes naive idealism. He tries his best to act mature among his fellow Experts, who are all adults, but he can occasionally come across as an impatient or precious brat. Daisaku is deeply aware of his own limitations; he possesses no superhuman powers or advanced combat training, and he sometimes feels frustrated and helpless, believing himself to be nothing without Giant Robo. This insecurity is a key part of his character, as he constantly struggles to prove his own worth beyond being merely the robot’s operator.
Daisaku’s primary motivation is to fulfill his father’s last wishes and carry on his work by keeping the world safe from the threat of Big Fire. He is driven by a strong sense of justice and a desire to see his father’s dream realized. His role in the story is central, as his command of Giant Robo makes him both the greatest weapon and the greatest weakness of the International Police Organization in their struggle against their enemies. He is the lynchpin of the Experts of Justice's power, and much of the conflict revolves around protecting him or exploiting his connection to the robot.
His relationships with others are vital to his development. Having lost his biological parents, he looks up to the other Experts of Justice as his guides, mentors, and surrogate family. He forms a particularly strong bond with Ginrei, a fellow Expert who acts as a protective older sister to him. Other senior members like Taisou serve as a wise mentor and father figure. However, his most significant relationship is with Giant Robo itself. Over years of fighting together, Daisaku has formed a deep bond and treats the immense machine not just as a weapon, but as a treasured friend and, for a time, his only family. This bond is so strong that Giant Robo is able to launch on its own and home in on Daisaku’s wristwatch signal if it senses he is in danger, demonstrating a mutual guardianship.
Daisaku experiences significant character development throughout his journey. He begins as a shielded, somewhat naive child, but the harsh realities of the world around him force him to grow quickly. He learns about the immense capacity for sacrifice that his friends have and suffers through their losses, which makes him question his own resolve. A major turning point in his development is the loss of his robot, which leaves him vulnerable and leads others to doubt him, but ultimately spurs him into action. He is confronted with the dark past of the world's clean energy source, the Shizuma Drive, which challenges his idealism. Through these trials, Daisaku matures from a protected child into a young man willing to sacrifice everything to protect the world. He ultimately comes to a profound realization of how close he came to becoming like his enemies, acknowledging that the guidance of his friends and mentors saved him from a darker path.
Despite having no remarkable natural abilities of his own, Daisaku’s strength lies in his indomitable spirit and the unique power he commands. He lacks any meaningful combat training and relies almost entirely on Giant Robo in battle. He commands the 30-meter-tall, nuclear-powered robot using the special wristwatch left to him by his father. The radio built into the watch relays his vocal commands to the robot, which is programmed to respond only to Daisaku's voice. He can also summon the robot in an emergency, as it can launch itself and home in on the watch's unique signal.
