==Behind the Scenes==
===Rider No.===
As the leading rider protagonist of Kamen Rider Zi-O, Zi-O is labeled and .
===Etymology===
"Zi" in Zi-O's name could mean either or , representing his "watch" and "Katakana" motifs while the "O" means . It may also be for the number 20 (2 - Ji, 0 - Ō), referencing that Zi-O is the 20th Heisei Rider.
==Notes==
*10th of the Phase 2 Heisei Riders 20th of the leading Heisei Riders overall, Zi-O was first foreshadowed in the Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders guidebook page 48, represented by a space following Build marked as "NEXT RIDER?" With Emperor having abdicated in April 2019, thus closing Japan's Heisei era, Zi-O was the last Heisei Rider.
*Kamen Rider Zi-O's official design was first revealed in Kamen Rider Buttobasoul accidentally and resulted in the machines needing to undergo maintenance after the reveal.https://twitter.com/TheRealMattHunt/status/1015195530090119168?s=19 His legend forms were soon after revealed by a Chinese printing industry staff unintentionally during the making of posters for Kamen Rider Battle: Ganbarizing.https://tieba.baidu.com/p/5790921663
*Zi-O is the second Rider with a magenta & black color scheme, after Decade.
*Zi-O's suit design is based on watches.
*Zi-O's boots have the katakana for on the soles.
*The clock hands on Zi-O's face point to 10:10, which is a rough common setting of watches and a reflecting his status as the 20th Heisei Kamen Rider.
**This makes Zi-O the first Heisei Rider since Kamen Rider Decade to incorporate his number into his design (the "X" on Decade's chest refers to 10).
*Uniquely, Zi-O's forms appear as an inversion of Decade's, where the forms conform to the core design and the summoned weapons are modified to either fit the trinket designs or the aesthetics of the rider's form, instead of both forms and weapons being their normal designs.
*Zi-O is the first Rider since Decade not to have a unique name for his default form.
*The prefixes added to Zi-O's Time Break for Rider Armor finishers are all taken from the original Riders' finishers:
**BuildArmor's Vortex Time Break is taken from the Vortex Finish.
**Ex-AidArmor's Critical Time Break is taken from the Critical Strike and Critical Finish.
**GhostArmor's Omega Time Break is taken from the Omega Drive finisher.
**GaimArmor's Squash Time Break is taken from the Squash finishers.
**FourzeArmor's Limit Time Break is taken from the Limit Break.
**OOOArmor's Scanning Time Break is taken from the Scanning Charge.
**DoubleArmor's Maximum Time Break is taken from Maximum Drive.
**DecadeArmor's Attack Time Break is taken from Decade's Attack Rides.
**KivaArmor's Wake Up Time Break is taken from the Wake-Up Fuestle, which is required for Kiva's finishing attacks.
**Den-OArmor's Ore no Time Break is taken from Momotaros' various nicknames for his Full Charge, usually 
**KabutoArmor's Clock Time Break is taken from the Clock Up maneuver that all the Riders of Kamen Rider Kabuto have, even though its use in a finisher isn't always necessary.
**HibikiArmor's Ongeki Time Break is taken from Hibiki's own Ongeki Finishers.
**BladeArmor's Lightning Time Break is taken from either the Lightning Slash, the Lightning Blast, or the Lightning Sonic.

**AgitoArmor's Ground Time Break is taken from Agito's Ground Form.

**It is the only DecadeArmor form which continues to use the original suit rather than replacing its parts with the Legend Rider's suit parts.
*Interestingly, Armor forms such as Kuuga, Decade, OOO, and Fourze are the only ones wielded by Sougo that don't have shoulder pads modeled after their respective Rider's Transformation trinket, but rather something either taken from that rider's default form or something used by that rider.
**KuugaArmor's shoulder pads are taken from his Mighty Form.
**KivaArmor's shoulder pads are modeled after Kivat-Bat the 3rd.
**HibikiArmor's shoulder pads are modeled after the Onigekiko Kaentsuzumi (a drum-like weapon he can use).
