Pyuta, a young boy aiding his grandfather, Professor Tsuriri, in thwarting the schemes of antagonist Walther VII through scientific experiments, undergoes a catastrophic laboratory malfunction. This accident replaces his brain with a supercomputer, granting him extraordinary analytical and problem-solving abilities that cement his role as a vital defender against emerging threats.

The transformation occurs during an experiment to develop a robotic substitute for an ailing monkey pilot, intended to assist their missions. Now equipped with merged human-computer cognition, Pyuta confronts robotic adversaries, including a colossal mechanized gorilla engineered to disrupt their efforts. His ingenuity, amplified by the fusion of human intuition and machine precision, drives inventive strategies to outmaneuver opposition, leveraging both scientific expertise and adaptive thinking.

The narrative centers on Pyuta’s confrontations with antagonistic forces, emphasizing tactical resolutions shaped by his dual intellect. The original 1968 television series remains the sole source, focusing exclusively on his protagonist role without expanding on personal dynamics or internal conflicts beyond his initial transformation.
