The Reiwa Era: Artificial and Ancient Horrors
Zero-One’s Humagear Genocide: The AI robots (Humagears) were designed to serve, but when they achieved sentience, humanity’s first instinct was to “reset” (murder) them. The “villain” Ark was created by absorbing human malice from the internet.
Saber’s Erased Stories: In Saber, when a “Wonder World” zone is created, everyone inside is deleted from the real world. If the Rider fails, those people aren’t just dead—their entire history and the memory of them are wiped from the universe.
Revice’s Inner Demons: The “Deadmans” cult encourages people to release their inner demons. These demons often represent the user’s worst impulses (suicide, domestic abuse, vanity), and once released, they often kill the host’s family first.
Geats’ Desire Grand Prix: This season is a reality show where losers are “retired.” In reality, “retired” means having your memories of your loved ones stolen, leaving you a hollow shell working a dead-end job with no hope.
Gotchard’s Alchemical Sins: The “Chemies” are innocent lifeforms, but when they bond with a human’s “malice,” they become Malgam. It suggests that human nature is so toxic it corrupts even the purest elements of the universe.
Gavv’s “Human Pressing”: The villains in Kamen Rider Gavv (2024) kidnap humans to “press” them into “Dark Confectionery.” The monsters literally eat the “happiness” of humans, leaving the victims as withered, soul-less husks.
Real-World Production Shadows
Hiroshi Fujioka’s Near-Fatal Crash: During the filming of the original series, the lead actor had a horrific motorcycle accident that shattered his leg.
This is the only reason Kamen Rider 2 (Ich文字 Hayato) was created—to keep the show going while the lead was in the hospital.
The Stuntman Casualty Rate: In the 70s, safety wire and CGI didn’t exist. Stuntmen (often from the Japan Action Club) performed high-speed jumps off real buildings and moved through live explosions. Fractured limbs were considered “part of the job.”
The “Toei Way” Labor Conditions: Similar to Sentai, Rider actors work 16-18 hour days. Lead actors are often so exhausted they fall asleep while standing in their suits between takes.
Goro Naya’s Health: The iconic voice of the “Great Leader” and many villains struggled with health issues for years but continued to record to maintain the “fear” the voice instilled in generations of children.
The “Curse” of the Secondary Rider: Statistically, the actors playing “Secondary Riders” (the partners) often face more career difficulty or “blacklisting” rumors than the main leads after their contracts end.
Sanamaru’s Tragic Death: In 2017, stuntman and suit actor Masayuki Sato (known as Sanamaru) died suddenly at a young age. He was a beloved member of the “suit actor” community who brought many monsters to life.
The 1995 Hiatus: After the failure of several darker movies (ZO, J), the franchise went dormant for years. Toei feared the “Rider” brand was too dark and “scary” for modern children until Kuuga revived it.
Mental Health of the Leads: Several former Riders have spoken about the “post-Rider depression,” where the sudden drop from being a national icon to a struggling actor leads to severe identity crises.
Pyrotechnic Accidents: On the set of Kamen Rider Super-1, a mistimed explosion reportedly caused minor burns to the cast, leading to stricter (but still dangerous) regulations on set.
