Century King Sun Driver

The https://twitter.com/bandai_ridertoy/status/1580487296130121728 is the transformation device used by Kotaro Minami to become the Black Locust Kaijin and later Kamen Rider Black Sun.
==Design==
The Century King Sun Driver is composed of the following parts:https://www.kamen-rider-official.com/zukan/items/2164 
*: The belt. It creates a special magnetic field around the abdomen to raise the output of the driver.
*: Special biological circuits formed inside the Century King Sun Driver. It optimizes the flow of , the root of life in the bodies of all living things, and rapidly amplifying that power. The process of Kaijin transformation incorporates the Vital Circuits of other creatures into the human body to drastically alter the structure of the creature. What is needed in this process is the Vital Photon crystals extracted from other living creatures, and the Kingstones were only high-purity crystals extracted from two special Locust Kaijin several decades ago and transformed under the special conditions of an eclipse.
*: A special material that makes up all parts of the Century King Sun Driver. It is a type of artificial cell capable of complex mechanical shape memory, and when not in combat, it is scattered around the body as cell fragments. When transformed, they are reconfigured according to a pre-installed blueprint and functions as a belt-shaped external organ that controls the Vital Photons. The external meters are remnants of the earliest driver designs, and were used by researchers of the time to collect data.
*: The central unit. Located at the center of the Vital Circuit, it functions as a detonator and reactor that generates the power necessary for transformation and battle. If the Kingstone is present inside, the output will increased and it is possible to manifest a peculiar power.
==Functionality ==
===Transformation===
Initially, Kotaro transforms into the Black Locust Kaijin via automatic bodily suggestion like the other Kaijin. To transform, Kotaro starts concentrating, his voice becoming more distorted and monstrous as the Sun Driver forms on his waist as a mass of black fibers before it condenses into the form of the belt. Steam then starts to come off of his body as the mechanical parts of the driver then close up automatically (although this is hardly ever shown on-screen) as Kotaro screams in pain, his body rearranging itself into a mass of black fibers as the exoskeleton plating closes over his body to complete his transformation into the Black Locust Kaijin. On some occasions, his grasshopper legs materialize from his back before the rest of his body changes.
After his rage against Bilgenia for turning Aoi Izumi into the Mantis Kaijin unlocks a new dormant power in his metamorphic biology, Kotaro is able to evolve further from the form of the Black Locust Kaijin into Kamen Rider Black Sun. To do this, Kotaro crouches and clenches his fists, concentrating as the Century King Sun Driver forms on his waist and steam starts to come off of his body. He then crosses his arms individually in the air before circling his arms into a pose. The driver's main body lights up with a shade of brilliant red before the parts surrounding the core slide into a circle before the covers on the top and bottom close up. Once the Driver closes up, the core then shines with a bright red as Kotaro is surrounded in a bright red light which changes into green as he transforms into his Kaijin Form. A transparent outline of his Rider Form then materializes over the Black Locust Kaijin before the eyes and lines start glowing and complete his metamorphosis in a bright flash of orange light that comes from the lines on Black Sun's body. The glow then dies down and the red eyes fade to black, completing the transformation.
===Finisher===
Although not showcased until the final showdown between Black Sun and Shadowmoon, the Century King Sun Driver is capable of amplifying the Kingstone's energy to power finishers. 
* Kingstone Flash: Black Sun gets into a stance and concentrates, slowly lowering his hands over the sides of the Sun Driver as the lines on his body start glowing. The core of the Sun Driver then begins to let off excess energy in the form of glowing red mist, with Black Sun's eyes starting to glow red. This charge grants Black Sun a temporary increase in power.
* Rider Kick: After performing the Kingstone Flash, Black Sun runs towards the enemy and jumps into the air, covering his foot with red energy from the Driver's core and performing a powerful Flying Side Kick on the enemy.
* Rider Punch: Black Sun performs an uppercut punch enhanced by the Red Kingstone's energies.
==Notes==
*The Century King Sun Driver is one of the two first commercially available Driver toys collectible to have fully automated motorized parts, the other being the Century King Moon Driver, a feature previously seen in a prototype driver that was first displayed at the The Henshin event in 2019.
**Although the toy was originally released on the CSM-level, a cheaper and more affordable version for the DX-line was announced in September 2023, making the Driver the first to have a toy whose DX version was released after the CSM.https://twitter.com/bandai_ridertoy/status/1699981154718560728
