Spider Man is a kaijin created by Shocker. It was the first kaijin to fiht Kamen Rider 1 and was killed by the Rider's trademark Rider Kick.
Spider Man abducted Hongo and brought him to Shocker where he went through the process and became the very first Kamen Rider. Chasing after Hongo and Professor Midorikawa after they escaped Shocker's lab, Spider Man bugged Ruriko Midorikawa in hopes she would lead him to her father, killing the man with Hongo taking the blame. After abducting Ruriko, Spider Man would be killed by Kamen Rider 1 with his "Rider Kick". Spider Man is later resurrected by Shocker as part of the Revived Kaijin Army before being destroyed by Tokageron's special bomb.
In Kamen Rider The First, Spider Man is reconned as "Spider" and assumes the identity of a taxi driver.
