This article is about a/an series entry (the 29th) in the Kamen Rider Series.
For the series' main character, Zi-O, see Sougo Tokiwa.

Kamen Rider Zi-O (仮面ライダージオウ Kamen Raidā Jiō) is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series. It is the twentieth and final series in the Heisei period run, the first series to be produced around the Reiwa period, and the twenty-ninth series overall. The series started on September 2, 2018, joining Kaitou Sentai Lupinranger VS Keisatsu Sentai PatrangerIcon-crosswiki in the Super Hero Time line-up after the finale of Kamen Rider Build. After Lupinranger VS Patranger’s conclusion, it was joined by 4 Week Continuous Special Super Sentai Strongest Battle!!Icon-crosswiki in February 2019 and later Kishiryu Sentai RyusoulgerIcon-crosswiki in March 2019. After the finale of Kamen Rider Zi-O, Ryusoulger would air alongside Kamen Rider Zero-One in a Super Hero Time block.

The show tagline is "Go beyond space-time!" (時空を超えろ! Jikū wo koero!). Much like Kamen Rider Decade, it commemorates all of the Heisei-era Kamen Riders to date.

The average ratings of the series was 3.0%.

She presents Sougo with an ominous warning "You will become the king of all time, Kamen Rider Zi-O, a demonic king destined to rule the world.”. Sougo takes up the mantle as Kamen Rider Zi-O to stop the Time Jackers from destroying the very fabric of space-time while protecting the legacy of the Heisei Kamen Riders that came before him. During his journey alongside Geiz Myokoin, a Kamen Rider from Tsukuyomi's future, and the mysterious prophet Woz who reminds Sougo of his demonic destiny, they will meet their esteemed predecessors who they must gain their trust and powers from in order to create a new future for the Kamen Riders and mankind itself. This is the story of a Kamen Rider who would be king, who will fight to save the past, present, and future, encountering the various Heisei Kamen Riders throughout space-time.

Main article: Kamen Rider Zi-O Episodes

Each episode title of Kamen Rider Zi-O is written in either katakana or hiragana, and includes the year relevant to that particular episode, often the premiere year of the original Legend Rider in the case of tribute episodes. Starting with episode 30, this format is reversed, starting with the year first, then the title. Similar to the previous two Rider series, many episodes still use the English language in most of their parts of the episode’s title, though there are exceptions.

As the show pays tribute to the Heisei period Kamen Riders, each episode title consists of a short phrase related to a particular Heisei Rider series and a year relevant to it. In every arcs, Decade's tribute is mostly involved in specific two episodes of three first arcs' respective Kamen Rider tribute, and plays more important roles in all episodes of the last arc. "*" denotes for Decade's tribute involvement on certain Kamen Rider tribute's episodes.

This series is divided into 4 arcs:

  • Episode 1-16: Birth of Zi-O arc: This arc introduces most of the main characters and the plot. It also pays tribute to Build, Ex-Aid, Fourze, Faiz, Wizard, OOO, Gaim and Ghost*.
  • Episode 17-30: Oma’s Day arc: This arc features White Woz who seeks to create GeizRevive, the 3 riders of the future, and the preparation of Oma’s Day. It also features tribute to Ryuki and Blade*. It also shows Sougo’s past and how he became to dream about being king.
  • Episode 31-40: Road to the King: This arc deals with Tsukuyomi’s past as she regains her memories. It also features tribute to Agito, Hibiki, Kiva, Kabuto* and Den-O.
  • Episode 41-49: Final Battle arc: This deals with Swartz’s real plan to become king and Sougo becoming Ohma Zi-O. It also features tribute to Drive and the Movie Riders.

Future Riders










  • Chase (チェイス Cheisu, 47-48): Taiko Katono (上遠野 太洸 Katōno Taikō)



  • Following only Kamen Rider Black RX before it, the final Showa era series, Zi-O will be broadcast through two eras of Japanese history. However, while Black RX entered the Heisei era with the death of Emperor Hirohito on January 7, 1989, Zi-O shall enter the new Reiwa era on May 1, 2019, with the scheduled abdication of Emperor Akihito on April 30 in 2019.
  • This season's concept of traveling across time through the previous installments is akin to an idea during the early development stages of Kamen Rider Decade, one of which would've been a "Kamen Rider Den-O 2", using the season's setting go travel across time around each rider's era.[2]
  • This is the first series since Fourze to have the titular rider only appear at the predecessor's summer film while OOO is the first have the transformation device appearing at the predecessor's series only.
  • This is the first series since Kamen Rider Gaim to not have a Blu-Ray miniseries.
  • On Zi-O's official Twitter page, there is an error on the banner that shows Ryuki wearing the Decadriver. This error was fixed as the banner have several Riders covering Ryuki's lower body. However, the image of Ryuki wearing the Decadriver remains on the banner.
    • Incidentally, Decade would appear in the series as well as changing into Ryuki. However, he does not use the original Decadriver and instead uses the Neo Decaderiver.
  • This is the first series since:
    • Ghost to feature secondary writers plotting the episodes.
    • Den-O to not have spring film in production during the series run.
  • The actors of the three Future Riders' are Super Sentai alumni.
    • Interestingly, they all starred in the 2010s Super Sentai series.
      • Although the first two played Sentai Rangers, the third played a Sentai Villain.
    • The fourth Future Rider's (voice) actor also voiced Sentai Monsters of the week.
  • Not counting Rider Troops, this series has the highest number of unnamed identity Riders, being (currently) 38 people.
  • Currently, Kamen Rider Zi-O has the highest number of returning Legend Riders, being 65 at present (including stand-in and suit-only appearances).
    • When including those Legend Riders who did not appear transformed and so are counted as returning allies, this number is further increased to 69.
    • Including the Legacy Riders and Another World Legend Riders further increases the count to 87.
    • Legend Riders in Kamen Rider Decade and Kamen Rider Ex-Aid are not counted since they were merely alternate versions.
    • Zi-O also has the highest number of returning cast from the previous series, with 47 actors, 7 actresses and 8 voice actors (including some who returned but portrayed/voiced new character).
      • Minority unique of Zi-O for returning characters are:
        • Rina Akiyama returned to portray as Mana Kazaya from Kamen Rider Agito.
        • Yuichi Nakamura portrays two characters from two different series. So far, there is no Kamen Rider series to have one actor to portray two different characters from different series (not counting Kohtaro Minami for being a character with two series)
  • Aside from Kamen Rider Heisei Generations FOREVER, the series does not have a tribute episode to both Kamen Rider Kuuga and Kamen Rider W.
    • Although the series feature Katsumi Daido from the W series, no characters from Kuuga have appeared in this series at all.
