Fourze Driver

"(after naming the activated Switches) Limit Break!"

- Finisher announcement

The Fourze Driver (フォーゼドライバ) is Kamen Rider Fourze's transformation belt that was given to Gentaro by Kengo Utahoshi. To transform into Fourze, Gentaro places four Astroswitches into the Switch Sockets (スイッチソケット), flips the red switches down to begin the countdown, then pushes the Enter Lever (エンターレバー) on the side of the belt, says "Henshin" (変換), and raise his right arm in the air.

By switching on a correspondent Astroswitch, or a combination of Astroswitches, before pushing the Enter Lever again, Fourze can perform a Limit Break (リミットブレイク) finishing attack.

While executing a Double Limit Break is possible, it is risky as it would completely drain an Astroswitch's power for a while, rendering one of them useless until they are completely recharged.

History
The Fourze Driver was invented by the father of Kengo Utahoshi, based on his research in Cosmic Energy. The Circle, Cross, Triangle, and Square Basement designs were based off of the pillars in Kyoto, where Utahoshi and his team researched the Hole over the city.

5 years later
5 years later, Gentaro tries his best to pursue Sanagiman into redeeming himself even destroying the belt by throwing it on the molten lava at a factory as a sign of truce. He later borrows the Fourze Driver from his present day self to fight alongside Wizard. After the future Gentaro returns to his own time, Haruto gives the Driver back to the Gentaro of the present.
