Also known as: 蜘蛛男
Kumo Otoko (Spider Man) is one of the monsters appearing in Kamen Rider (1st Series). True to his name, he's a monster themed around Spiders, and he was also the first opponent Kamen Rider 1 fought. He shoots spider silk and poisoned arrows from his mouth.
In the tokusatsu version, he has two arms and wears a cape, but in the manga version created by Ishinomori Shoutarou, he has four arms and does not wear a cape. He would inspire Kumo Augment 01 in Shin Kamen Rider, as well as appear in Toujima Tanzaburou Wa Kamen Rider Ni Naritai.
