|This article is about a/an transformation device in Kamen Rider Zi-O.|
When equipped with the Quiz Topper, the Mirai Driver belonging to Kamen Rider Quiz becomes the Quiz Driver (クイズドライバー Kuizu Doraibā). Before use, it is summoned from the Question Pendant (クエスチョンペンダント Kuesuchon Pendanto), a question mark-shaped pendant Mondo Douan wears around his neck.
The Quiz Driver consists of the following parts:
- Prodigy Engine (プロディジーエンジン Purodijī Enjin) - The Quiz Driver's main power source. It is built on both sides of the Quiz Driver and supplies electricity when sufficient power generation is impossible or when dealing with deathblows.
- RB Vibration (RBバイブレーション RB Baiburēshon) - The vibration generator in the front that takes the form of red and blue question marks. The question marks are converters that convert the surface's vibrations into energy via piezoelectric means. Although the energy made is small, Kamen Rider Quiz's suit has the ability to drastically raise the amount of electricity, nullifying this problem.
- Quiz Topper (クイズトッパー Kuizu Toppā) - The main command key. It slots onto the middle of the Quiz Driver, enabling transformation. The Quiz Topper changes its shape depending on what useful purpose it is needed for. To transform, the Quiz Topper takes a question mark-like form called Question Mode (クエスチョンモード Kuesuchon Mōdo). To activate deathblows, the Quiz Topper takes an exclamation mark-like form called Symbolic Mode (シンボリックモード Shinborikku Mōdo).
To transform into Kamen Rider Quiz, Mondo inserts the Quiz Topper into the Quiz Driver in Question Mode.
To initiate a finisher, Mondo removes the Quiz Topper and changes it into Symbolic Mode before re-inserting it.
- Final Quiz Flash (ファイナルクイズフラッシュ Fainaru Kuizu Furasshu): After asking a true/false question, Quiz jumps in the air only to be hidden by a giant sign with two panels marked "O" and "X" respectively. He then breaks through the correct answer's panel with his foot and hits the enemy with a spinning kick carrying projections of both symbols and an "!" on impact.
