He is the protagonist of Toei's 1978 Spider-Man television series, subsequently reappearing as a supporting character in the 2014–2015 Spider-Verse and 2018 Spider-Geddon comic storylines.

The success of Yamashiro and his giant mecha robot Leopardon made Toei adapt the concept to their Super Sentai franchise in Battle Fever J, ultimately making the character the narrative forefather of the Power Rangers.

The Takuya Yamashiro incarnation of Spider-Man is different from the traditional Marvel Comics version, with the former sharing the same name, costume, and primary superpowers.

His sister, Shinko and girlfriend, Hitomi Sakuma asked for his assistance in investigating the crashed Leopardon but Takuya refused as he had a race to compete in.

Back at his house, Garia told Takuya of his new costume and abilities and tested them out, before discovering the Iron Cross Army had kidnapped Professor Fujita.

As soon as the group arrived in their former safe zone, Earth-13, Takuya, who was already piloting the Leopardon, faced off against Solus, but the villain made quick work of the giant robot.
