==History==
===Background ===
Goro Hayase was Hongo's best friend and racing rival. Hongo always ended up beating Hayase by a small margin in races, although Hayase still considered Hongo as a friend, he was slowly getting carried away by the jealousy he felt for never being able to win. At some point, Hayase was kidnapped by Shocker but ended up joining voluntarily when he saw the opportunity to become a cyborg and beat Hongo.https://www.kamen-rider-official.com/zukan/character/1438
===Operation M1===
After joining Shocker, Hayase was turned into Scorpion Man and went to test his powers on Shocker slaves who were no longer able to work. He purposely lets Ito (one of the slaves) escape because he knew he would be a bait to lure Takeshi Hongo during Operation M1.https://www.kamen-rider-official.com/dictionaries/keywords_search?utf8=%E2%9C%93&search_dictionaries_form%5Bkeyword_for_title%5D=M1%E5%8F%B7
He followed Hongo, Ito and Ruriko and approached them saying he would help in the fight against Shocker, but it was all a lie to hand over Hongo's location and get Shocker to attack the location. While Takeshi was busy fighting off Shocker Combatmen, Ito was killed by one of Hayase's scorpions and Ruriko was kidnapped and taken to Scorpion Man's base.
After the attack, Hongo and Hayase went to save Ruriko, after arriving at the base they are attacked by more Shocker Combatmen and then Hayase reveals his true intentions in front of Hongo and transforms into the Scorpion Man. Hongo initially refuses to hurt his best friend, causing him to end up at a disadvantage in battle. However, he finally accepts reality and fights Scorpion Man, the Shocker mutant was not able to match Kamen Rider in the fight even with several Combatmen helping him and was easily killed with a Rider Scissors.
===Creation of Gebacondor===
A portrait of Scorpion Man appeared lining a wall with those of the other original four monsters (Man Spider, Bat Man, and Sarracenian), in a Shocker base where Gebacondor was created with the strongest traits of the past monsters defeated by Kamen Rider.
===Resurrection and attack on Toyo Atomic Energy Research Laboratory===
Scorpion Man was resurrected by Shocker as part of the Revived Monster Army, a team made up of all monsters that were previously killed by Kamen Rider, he went to attack the Toyo Atomic Energy Research Laboratory alongside Bat Man so they could steal the laboratory's resources and increase the power of Shocker's Japanese branch (which was weak near the North American and European branch), but both were impeded by a force-field that protected the site, they returned to base and warned the Great Leader that they weren't able to completing the invasion, the Great Leader was furious and ordered the Shocker scientists to build the Barrier Destruction Ball, a bomb strong enough to break the force-field, however, this bomb would need a very strong monster to be hurled from a safe distance, causing the Great Leader to order the capture of a human qualified to be turned into that monster, that human was Ken Nemoto, a soccer player who was captured by Shinigami Chameleon and Man Spider and was turned into Tokageron.
During a second invasion of the Toyo Atomic Energy Research Laboratory, Scorpion Man alongside the members of the Revived Monster Army and Tokageron faced Kamen Rider, but they were easily defeated and killed in the explosion of the Barrier Destruction Ball.

==Notes==
*Scorpion Man was featured in the "monster gallery" accompanying the opening narration, following the opening sequence, from episodes 5 to 13.
*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.
