Spider Man is the first kaijin created by Shocker to appear and an antagonist in the original 1971 Kamen Rider series.
He later reappears as Space Spider Man and a major antagonist in the film Kamen Rider x Super Sentai x Space Sheriff: Super Hero Taisen Z.
Spider Man abducted Takeshi Hongo and brought him to Shocker to go through the process of being converted into the first Kamen Rider. After Takeshi Hongo escaped along with ex-Shocker scientist Professor Midorikawa, Spider Man was sent to track him down.
He killed Midorikawa and pinned his death on Hongo before abducting the professor's daughter Ruriko. He was later killed by Kamen Rider 1 with his Rider Kick.
Spider Man later reappeared as a part of the Revived Kaijin Army. He was destroyed by Tokageron's special bomb.
