Kamen Rider Zero-One (仮面ライダーゼロワン Kamen Raidā Zerowan) is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series. It is the first series to debut during the Reiwa period and the thirtieth overall. The series premiered on September 1, 2019[1], joining Kishiryu Sentai RyusoulgerIcon-crosswiki in the Super Hero Time line-up after the finale of Kamen Rider Zi-O. After Ryusoulger's conclusion, it will be joined by Mashin Sentai KirameigerIcon-crosswiki at an unknown date.[2]

The catchphrase for the series is "There's only one strongest company president in the world! It's me! (世界最強の社長はただひとり!オレだ! Sekai saikyō no shachō wa tada hitori! Ore da!) [3]


Japan has entered a new era. Hiden Intelligence, the leading company in the field of artificial intelligence (AI) has developed a way to utilize these A.Is in human form, known as HumaGear. They're no different from humans and have become a staple in both public and private life. However a terrorist organization known as "" has hacked into several of these HumaGears and turned them against society for the sake of eliminating humanity. In an effort to combat this, the government has established the Artificial Intelligence Military Squad, or A.I.M.S., to destroy these sabotaged HumaGears.

Meanwhile, a young but failing stage comedian named Aruto Hiden has suddenly been appointed the chairman of Hiden Intelligence after his grandfather's death. Although he was initially uninterested, he witnessed firsthand of the terrorist attacks by "" and decided to fight as Kamen Rider Zero-One for the sake of keeping up appearances as chairman. From here on out, an explosive war has been ignited between Aruto, MetsubouJinrai.NET, and A.I.M.S.

Suit Actors


  • With "zero" in Japanese and "one" in Japanized-English, Zero-One can be read as Rei Wan (零 ワン) in Japanese, referencing the fact that he is the Kamen Rider of the Reiwa era.
    • The characters "zero" and "one" are known in tech, electronic and the mathematic world as Binary numbers, which is fitting for the series due to its theme of artificial intelligence.
  • Coincidentally the series' release date matches the name of the show/rider (September 1st, Zero-One/01).
Kuuga-ZeroOne Concept

From upper left to lower right, Leon, Lady, Rider 3-Changes, Mecha Rider

  • Being the first Reiwa series, the rider designs contain several elements taken from the discarded concepts of Heisei's first, Kamen Rider Kuuga. For example:
    • The main rider is based on insects (Kuuga and Zero-One), a second rider based on land creatures (Leon and Vulcan), and a third female rider (Lady and Valkyrie).
    • Three base forms of birds (eagle and falcon), tiger, shark, and a form of transforming robots.
  • The promotion video of Zero-One uses a new beginning style similar to Marvel Cinematic Universe's early introduction version.
  • Coincidentally, Zero-One shares the name with the Phone Braver from sci-fi detective series K-tai Investigator 7.
  • This series opening credits use the same font style that was used in Kamen Rider Zi-O.
  • This series marks the first time since Hibiki where Seiji Takaiwa is not the suit actor of the main protagonist's Rider form. Instead, Takaiwa portrays Kamen Rider Horobi starting in episode 4 while Yuya Nawata took on the titular role of Zero-One.[6]
  • This is the first season since Kamen Rider Kuuga to not use the (vocal/instrumental) opening for the next episode preview. Instead, they used a standalone instrumental for the next episode preview.
