The first series to have a superhero (as opposed to a costumed pilot) ride a giant robot. The success of this series led to the revival of the Sentai Series as the "Super Sentai Series." Battle Fever J (1979), the 3rd Sentai Series, was the first "Super Sentai," as the five heroes therein rode a giant robot.
This version of Spider-Man appeared in the 2015 comic book story line "Spider-verse", featuring multiple versions of spider-man from alternate universes. The robot Leopardon also appeared and played a key role in defeating the villains.
This Toei-produced TV tokusatsu version of the famous Marvel superhero was part of a deal that Marvel made with Toei: For four years, Toei could adapt any of Marvel's characters. The result was this series and Battle Fever J (1979), which was a loose adaptation of Captain America. The next two Super Sentai shows, Denshi Sentai Denziman (1980) and Taiyo Sentai Sun Vulcan (1981), featured Marvel Comics Group in the credits, but oddly enough, no Marvel characters were used in those shows.
John Semper used the idea of Spider-Man having a giant robot in the final multi-part story of his Spider-Man: The Animated Series (1994) series in which Spider-Man visits a parallel universe where his much more successful, wealthy alter-ego has one.
Producers Tôru Hirayama and Susumu Yoshikawa originally wanted to make a series faithful to the famous web-slinger's origins, but Bandai, one of the sponsors, told the studio to add a giant robot (as giant robots were all the rage in Japan). Hirayama and Yoshikawa met their demand with complete incredulity, and they reluctantly rewrote Spidey's origins completely for the show.
