OVA
Description
Go is a central protagonist who emerges from a capsule with no memory of his past, stepping into a leadership role within the new Getter Team after the original team disbanded. His origin is rooted in tragedy and scientific ambition, as he is later revealed to be an artificial human. He was created by Doctor Saotome using the scientist's own genes combined with those of his daughter Michiru, all through the powerful and mysterious Getter Rays. This genesis was not an accident but a deliberate act to engineer a pilot capable of controlling the immense power of the Shin Getter Robo and the Shin Dragon.

Physically, Go appears as a young man of average height and build, characterized by his distinctly short green hair. His typical attire evolves from an initial red jumpsuit to a white pilot suit accented with red, marking his transition into a formal member of the Getter Team. In some sources, this incarnation of Go is also known as Go Saotome, reflecting his genetic connection to his creator.

In terms of personality, Go initially presents as remarkably calm and displays an almost emotionless, apathetic demeanor. He is a being searching for purpose, largely defined by a powerful, instinctual drive to protect a young woman named Kei. This desire is not born from conscious emotion but is revealed to be a built-in genetic instinct, as Kei is actually Genki Saotome, the younger daughter of Doctor Saotome. The genes he inherited from Michiru are the source of this powerful need to safeguard her sister. As the narrative progresses, Go begins to evolve beyond his programmed instincts. He gradually develops real emotions, and his bond with Kei deepens into genuine friendship, an affection he also extends to his other teammate, Gai. While he maintains a reserved relationship with the original Getter pilots, he demonstrates a clear and respectable regard for their experience and abilities.

Go's primary motivation is intrinsically linked to his creation and his connection to Kei. He is driven to fulfill his purpose of piloting Shin Getter Robo to combat the Invaders, the alien threat that plagues the world. Simultaneously, his actions are heavily guided by his instinct to protect Kei, a mission that becomes the catalyst for his emotional awakening. The activation of the Shin Dragon is directly tied to his ability to gain these emotions, making his personal development a key component of the story's larger conflict.

His role in the story is pivotal as the lead pilot of Shin Getter-1, the primary defender of Earth in the aftermath of a global catastrophe that decimated the human population. Following a devastating explosion that wiped out ninety-nine percent of humanity, Go emerges from the ruins as the main hope for survival, piloting the powerful Shin Getter Robo alongside his co-pilots Kei and Gai. He is a central figure in the new Getter Team, and his existence is a living testament to Doctor Saotome's complex and dangerous legacy.

Key relationships define Go's journey. His most significant bond is with Kei, starting as a programmed directive to protect and evolving into a true emotional connection. His relationship with Gai develops into a steadfast friendship built on mutual respect and shared experience. Although he is the pilot of the Shin Getter, he also shares a dynamic with the surviving members of the original Getter Team, like Ryoma Nagare, who pilots the Black Getter, showing them deference while forging his own path.

Throughout the story, Go undergoes significant development. He begins as a near-blank slate, an artificial being with no memories and little emotion. His arc is one of self-discovery and acquiring humanity. Through his interactions and his protective instincts towards Kei, he learns to feel, to form bonds, and to act not just on programming but on genuine emotion, which is ultimately what allows his full power as a pilot to manifest.

Go possesses several notable abilities that set him apart from a typical human pilot. As a being born from Getter Rays, he has a unique, almost psychic connection to the Getter machines. He is able to pilot the Shin Getter Robo and the Shin Dragon without any formal training or equipment, and on occasion, he can even control these colossal robots remotely without being inside a cockpit. He is also a formidable physical combatant, capable of grappling with the monstrous Invaders unassisted. Furthermore, his connection to the Getter Rays grants him an extraordinary ability to communicate with the spirits of the deceased, as demonstrated when he summoned the spirits of Michiru and Musashi to aid the original Getter Team in battle. He also does not appear to age, remaining physically unchanged in the thirteen-year gap between the initial disaster and the main story.
