Created from the brilliant mind of Goro Ibuki, Jet Jaguar represented the advancement of technology to its utmost. Working in secret in his lab, the inventor's triumphs didn't go unnoticed. Watching from a distance, agents of Seatopia awaited for their chance to capture the scientist and take hold of the marvelous robot. Lying in shrouding mystery, they awaited to spring their trap at last. Seizing hold of the man and a small boy, they sought to bring him to the undersea kingdom, until the rising Megalon revealed its ghastly face. Unknowingly setting free the humans, the insect raged into its set path, dumbly following the Seatopia controlled Jet Jaguar. Only by using his medallion with its built in override voice command, was Goro able to overthrow Seatopia's control. Witnessing the threat at hand, the inventor immediately ordered the humanoid robot to retrieve Godzilla from the devastated Monster Island. Flying at an unimaginable speed of over mach three, the machine accomplished its mission as it flew ahead of the nuclear saurian that it had summoned.
Jet Jaguar was the result of a contest Toho had in mid-to-late 1972 for fans to come up with a new hero for them to use (to capitalize on the many tokusatsu and anime superhero and super robot shows that were all the rage at the time). The winner of the contest submitted the drawing of a robot called Red Alone. The robot resembled Ultraman, Spectreman, and Mazinger Z (all of which were very popular at the time). The robot was renamed Jet Jaguar and was set to star in a film vehicle for him, titled Jet Jaguar vs. Megalon, which pitted him against Megalon (a previously unused Godzilla villain). However, Toho figured Jet Jaguar would not be able to carry the film on his own, in screen appearance or marketing value, so during pre-production, even after doing some tests and storyboards, the project was shut down for several weeks, until screenwriter Shinichi Sekizawa was called in to rewrite the script to add Godzilla and Gigan to have more marquee value. The resulting film, Godzilla vs. Megalon, paired Godzilla with Jet Jaguar against both Megalon and Gigan.
