Supaidāman (スパイダーマン) aired in Japan for one season from 1978-1979. Spider’s suit is familiar, but in this series his main power is that he, um, pilots a transforming robot named Leopardon. From Wikipedia:
Although the show’s story was criticized for bearing almost no resemblance to the Marvel version, the staff at Marvel Comics, including Spider-Man’s co-creator Stan Lee, praised the show for its special effects and stunt work, especially the spider-like movement of the character himself.[5] While it is said that Marvel initially opposed the addition of Leopardon, the robot was viewed as a necessary gimmick to attract younger viewers and was ultimately kept. The show’s mechanical designer, Katsushi Murakami (a toy designer at the time), expressed concern about Toei’s capability to market Spider-Man to Japanese audiences and was given permission by producer Yoshinori Watanabe to take whatever liberties he deemed necessary. Murakami came up with the idea of giving Spider-Man an extraterrestrial origin, as well as a spider-like spacecraft that could transform into a giant robot (due to the popularity of the giant robot shows in Japan at the time).
