Spider Man

The Spider Man is a kaijin created by Shocker. It was the first kaijin that fought Kamen Rider 1 and was killed by the Rider's trademark Rider Kick.

Personality
Spider Man is a loyal member of Shocker capturing Takeshi Hongo for getting more members for the organization and killing Professor Midorikawa for helping Hongo escape and defecting Shocker.

Abilites
Spider Man has heightened strength and agility, enabling him to accomplish jobs like assassinations and abductions. Like a spider, he can shoot out powerful strands of webbing to capture or strangle his victims along with shooting darts from his mouth that contain enzymes that liquefy his target on contact.

Part in Series
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 Midkorikawa 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". He was later resurrect by Tokageron as part of his Monster Army, only to die again.

Kamen Rider The First
In Kamen Rider The First, Spider Man is simply known as Spider and is a field captain in Shocker's ranks. He is responsible for covert assassination missions, and is behind several "mysterious" deaths prior to and during the course of the film. He is eventually destroyed by Kamen Rider 1's Rider Kick.

Legacy
Spider Man and fellow Shocker Inhumanoid, Bat Man have become "icons" for the first kaijin created or encountered in most Kamen Rider Series, with the kaijin being either spider or bat based.
