Trimorphos

The Trimorphos is a car which serves as the personal Rider Machine of Kamen Rider Fast Racing, as well as a support mech for combat thanks to the weapons in the front of the car for him to use. Like the Riders, it can bypass the time distortions caused by an Maldroid. When present at the scene, it also provides Kamen Rider fast racing with his weapons, the Wheel Saber and Door Blaster, by summoning them from the hollow section of its front portion whenever Dash calls for them. It can be controlled remotely to assist kamen Rider fast racing in battle when needed.

When kamen Rider fast racing activates a Tire Change, if the Trimorphos is at the scene, it creates the Tire by first drawing its left front wheel in, then forming the Tire, and lastly ejecting the Tire by using its left wheel to push it out so that it can attach to kamen Rider fast racing

Similar to Duo Rider and the Revol Carrier with the Duo Cycle, Auto Rider's current form and Auto Charger arsenal can affect Trimorpho's armaments via Tire Enhancements, which are activated when the shift cars are installed into Trimorpho's back panel, which allows the Trimorphos to use the shift cars Tire Modules for attacking purposes.

Modes
Like fast racing, Trimorphos has three alternate modes that it can transform into during battle.

Speed form
Speed Form is Auto Cruiser's default sports car-based mode.
 * Length: 4.9m
 * Weight: 1450kg
 * Hp: 3000ps (2206kw)
 * Maximum speed: 560km/h

This mode is Trimorpho's most balanced form. On the paved roads of the city, it can go the fastest of all the forms, making it suited for high-speed chases or getaways.

In combat, aside from Tire Enhancements, Trimorphos can perform the Cruiser Blast attack, where it fires lasers from the car's built-in cannons on the front.

In one episode, Trimorphos briefly changed into Technic Form to combat the dash Cycle while in possession of Mech Warrior by ejecting the cabin portion to strike it with the claws in order to forcibly disengage the combination.

Wild Form
Wild Form is Auto Cruiser's dune buggy-based mode.
 * Length: 4.9m
 * Weight: 1450kg
 * Hp: 3000ps (2206kw)
 * Maximum speed: 239km/h

Just like fast racing's transformation into Wild Form, Auto Cruiser is much slower in this mode. But in exchange, it has much more power and maneuverability, bouncing around the battlefield with its buoyant wheels and ramming giant Attack-Bots with ease.

In combat, aside from Tire Enhancements, Trimorphos can perform the Cruiser Crush attack, where its wheels enlarge in order to allow the buggy to run over an enemy.

Technic Form
Technic Form is Auto Cruiser's garbage truck-based mode.
 * Length: 4.3m
 * Weight: 1450kg
 * Hp: 3000ps (2206kw)
 * Maximum speed: 219km/h

This transformation is Trimorpho's slowest mode. However, it is one of the most versatile like fast racingr's own Technic Form, thanks to the claw-like manipulator arms it has, allowing it to directly interact with the surroundings. It is also able to travel up building sides.

In combat, aside from Tire Enhancements, Auto Cruiser can perform the Cruiser Smash attack, where its claws allow the truck to cut through enemies with ease.
