In Toei's Spider-Man series, Spider-Man's civilian identity is Takuya Yamashiro (山城 拓也, Yamashiro Takuya), a 22-year-old motocross racer. Takuya assumes the identity of Spider-Man when he dons the protective suit known as the Spider-Protector. He is genetically altered as a result of the Spider-Extract injected into his body by Garia, gaining spider-like abilities such as being able to stick to and climb up walls. Spider-Man spends most of the series fighting off Ninders (the Iron Cross Army's foot soldiers). He rarely finishes the Machine BEMs by himself, as they usually turn giant, forcing Spider-Man to summon Leopardon. Spider-Man thus occupies a peculiar position in the Japanese superhero genre of having no signature finishing move or weapon, such as Kamen Rider's Rider Kick or Kikaider's Denji End.
