Scorpion Man (さそり男 Sasori Otoko, 3, 13, Rider vs Shocker & Super Hero Taisen) (a.k.a. Scorpion Human (さそり人間 Sasori Ningen)) - A scorpion monster, originally known as Goro Hayase (早濑 五郎 Hayase Goro) (best friend of Takeshi Hongo) who uses his old identity to approach and attack Hongo.

Character History

Goro Hayase was Hongo's rival in racing, who became entirely consumed by his rivalry. At some point, he joined Shocker and became a monster to have a chance at surpassing and killing Hongo.

As Scorpion Man, he pursued and killed people who attempted to escape from Shocker. Meanwhile, as Hayase, he approached Hongo, seemingly to help against the organization, but actually working to have his chance at revenge. However, once he revealed his identity as the very same Scorpion Man they were searching for, he couldn't defeat Kamen Rider in direct combat. He was destroyed by Kamen Rider 1's Rider Scissors attack. Monster, Scorpion Man

Scorpion Man was later resurrected by Shocker as part of the Revived Monster Army and faced Kamen Rider 1 again, but Hongo fought without hesitation and easily beat him in their second battle. He was destroyed afterward by the detonation of Tokageron's special bomb. Tokageron and the Big Monster Army Scorpion Man also made a brief return appearance in the crowd shot of the monster army of the Kamen Rider vs. Shocker movie, but did not actually have an active participation there, never actually reappearing after the initial group shot.

Super Hero Taisen

Scorpion Man was revived as part of Dai-Shocker in the Super Hero Taisen incident, led by Tsukasa Kadoya/Kamen Rider Decade, rivaling Captain Marvelous/Gokai Red and Dai-Zangyack. However, Rider Hunter Silva of Dai-Zangyack and Doktor G of Dai-Shocker overthrew their respective leaders and joined forces to destroy the Kamen Riders and Super Sentai.

During the final battle, Scorpion Man was killed by Kamen Rider OOO's finishing attack with his Medajalibur, the OOO Bash along with Hades God DagonIcon-crosswiki.png, Goaster, and Isoguin Jaguar.

Powers and Abilities

Scorpion Man has the ability to quickly burrow underground. He can roll fast enough to confuse enemies. His physical abilities were inferior to Rider 1's initial power, and after his later training and progression, he is even weaker in comparison, being completely unable to keep up with him during their later battles.


Scorpion Man controls an army of robotic scorpions that release corrosive acid and is able to use his pincer as a weapon. Monster, Scorpion Man

Behind the Scenes


to be added


  • Since the full trope of what a Rider has not been established at this point, Scorpion Man could be considered the first Rider-like character who gains power for the sake of defeating the Rider, due to modifying his body and keeping his free will other than his desire for vengeance; possibly inspiring similar actual Riders later like Kaito Kumon.
