Kamen Rider Zi-O

is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series. It is the twentieth and final entry of the Heisei Era, serving to commemorate its 20th Anniversary, and the thirty-third series overall. The series premiered on September 2, 2018 and joined in the Super Hero Time line-up after the finale of Kamen Rider Build. After Lupinranger VS Patranger’s conclusion, it was joined by in February 2019 and later in March 2019. 
The motif of the series is time. The series' tagline is . Much like Kamen Rider Decade, it commemorates all of the Heisei-era Kamen Riders to date.
The average rating of the series was 3.0%
==Production==
The initial plan for the 2018 season was surposed to be Kamen Riders piloting giant robots to fight each other. However, crews had stated that it shares too much similarities with Super Sentai franchise. Therefore, the brainstorm groups added a concept that those robots are able to travel in time, and makes sense if the protagonist can meet with privious Legend Rider, and put into production following this idea.https://news.mynavi.jp/article/20181229-kamenrider/
Producer Shirakura stated that like Decade, Zi-O was the culmination of the entire Heisei-era, which would end when Prince Naruhito ascended to the Japanese throne in 2019. Viewership ratings from Build were at a new low, and Shirakura noticed that those ratings were 40% higher during Decade. Shirakura was also extremely hesitant to bring back former actors as well as deal with the tricky concepts of time travel like Den-O, but his associate producers convinced him to tackle them as Shirakura was willing to give it a try.
Both Gaim and Ghost had began the idea of having multiple Riders use the same transformation belt, similar to how Super Sentai Rangers transform using the same device but in a more controlled setting. Shirakura had liked the idea, and allowed both Geiz and Tsukuyomi to use a Ziku-Driver like Sougo to transform. During the original designing stages for Zi-O's suit, Shirakura was interested in the motif of time itself he felt it symbolized the Heisei-era, so "Rider" in katakana was added to Zi-O's mask for his default form. To differentiate Zi-O's means of transportation and time travel, the Time Mazine was introduced as opposed to a train and other supernatural means.

==Notes==
*Like Kamen Rider Black RX, Kamen Rider Zi-O was broadcast through two eras of Japanese history. However, while Black RX entered the Heisei era with the death of on January 7, 1989, Zi-O entered the new Reiwa era on May 1, 2019, with the scheduled abdication of on April 30, 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 have been a "Kamen Rider Den-O 2", using the season's setting go travel across time around each Rider's era.https://www.toei.co.jp/tv/decade/story/1188606_1564.html
*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 following Kamen Rider Gaim to not have a Blu-Ray miniseries.
*On Zi-Os 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.
*An Indonesian dub premiered on RTV on March 15, 2021 https://twitter.com/langitrtv/status/1371292876949262338?s=21&t=9N6xSdDpJgYQOKuaI7wIIw. The dub was made available on YouTube in the same year. The show received an English-style logo for the ads.
