|This article is about a/an transformation device in Kamen Rider Zi-O.|
The Ohma Zi-O Driver is composed of the following parts:
- Ohma Creator (オーマクリエイザー Ōma Kurieizā) - A golden device located on the left of the Ohma Zi-O Driver. It manages suit creation. It contains information on each of the Heisei Kamen Riders' creation (absorbed from every Ridewatch), and creates Ohma Zi-O based on this information. Additionally, it is an input device that works in tandem with the Ohma Destruser to allow transformation and finishing attacks.
- Ohma On Ruser (オーマオンリューザー Ōma On Ryūzā) - The button on top. Locks the Ohma Ziku Circular in place.
- Ohma Ziku Matrix (オーマジクウマトリクス Ōma Jikū Matorikusu) - The red circular sections on the Ohma Creator and the Ohma Destruser. Responsible for materialising Ohma Zi-O's suit and armor.
- Site Window (ザイトウインドー Zaito Uindō) - The central display. In addition to displaying Ohma Zi-O's original time co-ordinates, it displays characters corresponding to ability activation.
- Ohma Ziku Circular (オーマジクウサーキュラー Ōma Jikū Sākyurā) - The main unit. When rotated at high speeds, data from the Ohma Creator and Ohma Destruser are expanded and loaded into the Ohma Ziku Circular in a concentric manner. Additionally, the energy generated by the rotation is accelerated and amplified, allowing transformation and deathblows.
- Ohma Destruser (オーマデストリューザー Ōma Desutoryūzā) - A golden device located on the right of the Ohma Zi-O Driver. It manages the destructive power of deathblows. The history of each Heisei Kamen Riders' destruction is archived here, and Ohma Zi-O is formed according to this information. Additionally, it is an input device that works in tandem with the Ohma Creator to allow transformation and finishing attacks.
All of the Ohma Zi-O Driver's functions are accessed using the Ohma Creator and Ohma Destruser. Pressing them simultaneously activates either transformation into Ohma Zi-O or a desired finisher.

|Sougo Tokiwa/Sougo Tokiwa (previous timeline)|| || Pre-Series (2068 version)
Due to Geiz's sacrifice in protecting Sougo from Swartz's attack, Sougo's grief (combined with Tsukuyomi's supposed betrayal and the fact he was being manipulated by Swartz this whole time) became a catalyst, resulting in his Ziku Driver transforming into the Ohma Zi-O Driver. As a result, Sougo's destiny about becoming Ohma Zi-O was ultimately fulfilled. After the battle ended which resulted in both Tsukuyomi and Swartz's deaths, Sougo decided to use his new-found power to undo the damage Swartz inflicted upon both his and the other Heisei Riders' timelines. After this, the Ohma Zi-O Driver disappears from existence.
