Scorpion Man

Scorpion Man (voiced by Michihiro Ikemizu) is a scorpion monster, originally known as Goro Hayase (早濑 五郎 Hayase Goro) (an old friend of Takeshi Hongo) who uses his old identity to approach and attack Hongo. He controls an army of robotic scorpions that release corrosive acid. Has the ability to burrow underground, use his pincer as a weapon, and could roll fast enough to confuse enemies. He was destroyed by Kamen Rider #1's Rider Scissors.

He was later resurrected by Shocker as part of the Revived Kaijin Army and faced Kamen Rider #1 again, but Hongo fought without hesitation and easily beat him in their second battle. He was destroyed afterwards by the detonation of Tokageron's special bomb. Scorpion Man also made a brief return appearance in the monster army of the Kamen Rider vs. Shocker movie, but did not actually have an active participation there.

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. The two evil organizations united and faced off against the combined forces of the Super Sentai and Kamen Riders. During the final battle, Scorpion Man was killed by Kamen Rider OOO's finishing attack with his Medajalibur, the OOO Bash along with Hades Wise God Dagon, Ghoster, and Isoginjaguar.

Scorpion Man was one of the monsters in a Space Shocker force led by Space Spider Man which fought a group of Kamen Riders and Super Sentai teams that came to back up Kamen Rider Beast. He was attacked by Kamen Rider Hibiki, who used his Ongekibou Rekka on him.

Scorpion Man was resurrected as part of the revived Badan Empire.
