Arigabari - A giant anteater monster. Able to insert a poison called "Amazon's curse" that could even melt the human body, and had in one hand a retractable tentacle and in another a large claw. Was strong enough to shrug off Rider #2's Rider Kick and defeat him in direct combat. A member of Shocker Amazon, not the Japanese division, sent to Japan to work under Colonel Zol. Initially, easily defeated Kamen Rider #2, however, Hayato trained and developed a new finishing technique. In their rematch, he was destroyed by Kamen Rider #2's Rider Swirling Kick.
