Meteoro, known as Go Hibiki in the Japanese version, inherits the rebuilt Mach 5 racing car after his brother Ken’ichi—a motor engineer and test driver—is presumed dead during a prototype accident. Their father, Daisuke Hibiki, retrofits the vehicle with the experimental “X” engine salvaged from the crash, embedding a “Safety Seven” system to safeguard its driver. Driven to honor Ken’ichi’s legacy, Meteoro enters the professional racing circuit, confronting corporate sabotage and ruthless rivalries while striving to master the Mach 5’s limits. The car’s capabilities escalate when its speed surpasses 555 km/h, triggering the “Mirage Shot” function and propelling Meteoro into interdimensional realms. There, he allies with rebels against Handler, an alien warlord hunting fragments of the Ezekiel Wheel, a cosmic energy source dispersed across time. Racing pivots into a high-stakes mission to reclaim the Wheel’s pieces before Handler harnesses their power, intertwining breakneck competition with clashes against extraterrestrial forces. Meteoro’s crew includes Mai Kazami, a tenacious reporter aiding his investigations, and her mischievous younger brother Wataru, who mirrors the original series’ Spritle. A chimpanzee named Rocky serves as their loyal companion. His unresolved grief over Ken’ichi’s disappearance fuels his resolve to uphold his brother’s engineering legacy through the Mach 5’s advancements, while familial bonds anchor his moral compass. As Handler’s ambitions intensify, Meteoro embraces his role as Ken’ichi’s successor, wielding the Mach 5 not only as a racing machine but a temporal navigator. The Safety Seven system’s defenses face relentless trials against Handler’s armies, underscoring Meteoro’s dependence on Daisuke’s engineering and Ken’ichi’s unfinished breakthroughs. Though his efforts stabilize the timeline by the saga’s end, lingering enigmas—Ken’ichi’s fate, the Mach 5’s latent potential—echo beyond the final race, leaving horizons tantalizingly unresolved.
