Tridoron

The Tridoron (トライドロン) is a car which serves as the personal Rider Machine of Kamen Rider Drive, as well as a support mech for combat thanks to the weapons in the front of the car for him to use.

Functionality
Like the Shift Cars, it runs on Core Driviars and can bypass time distortions caused by a Roidmude. It also provides Drive with his weapons, the Handle-Ken and Door-Ju, by summoning them from the hollow section of its front portion whenever Shinnosuke calls for them. Mr. Belt can also control it remotely to assist Drive in battle when needed. Tridoron also has an ejector seat, which is done by twisting a yellow-and-black striped pull lever, then pull on it, which will send Drive flying upwards. While in standby mode or just not in battle, Tridoron's hollow section is covered with a Special Investigation Unit insignia.

It was created by Mr. Belt and Rinna after the "death" of Protodrive, with Mr. Belt wanting to have a means to fight beside the warrior he chooses as Drive.

When Drive initiates a Tire Exchange (タイヤ交換), Tridoron creates the Shift Tire (シフトタイヤ) by first drawing its left front wheel in, then forming the Shift Tire, and lastly ejecting said Shift Tire by using its left wheel to push it out so that it can attach to Drive.

Similar to Kamen Rider Double and the RevolGarry with the HardBoilder, Drive's current form and Shift Car arsenal can affect Tridoron's armaments via Tire Enhancements (タイヤ増える), which are activated when the Shift Cars are installed into Tridoron's back panel, which allows Tridoron to use the Shift Tires for attacking purposes.

History
When Shocker altered the past using the History Modifying Machine, Shinnosuke, formerly a Shocker Rider having been freed of his brainwashing, drove Tridoron to victory in the Rider Grand Prix, with the help of allied Riders and the Ride Booster Set, beating Kamen Rider 3's TriCyclone car and other past brainwashed Kamen Riders in their Rider Machines. Reunited with the Ninningers during the final battle against Shocker, Drive was given a special by, transforming Tridoron into an  which combined with  to become Shurikenjin Tridoron, destroying the Rider Robo. When Mr. Belt becomes evil and forces the Type Tridoron transformation, Shinnosuke managed to escape from the form by yanking Mr. Belt off and punching him, which caused Tridoron to be damaged.

It was fixed sometime later and after the destruction of Gold Drive and Sigma Circular, it was locked beneath the Drive Pit alongside, Ride Chaser, Ride Macher and all of Drive's arsenals.
