Aruto can transform into Kamen Rider Ark-One by using the Ark-One Progrisekey in the Ark Driver-Zero, converting it into the Ark Driver-One.https://news.tokunation.com/2020/06/29/introducing-kamen-rider-ark-one-67649 Though Ark-One is primarily the final form of Ark-Zero, it is also classified as a corrupted form of Zero-One.https://www.kamen-rider-official.com/zukan/kamen_rider_members/197 Horobi only used this form in one of Izu's simulations.
Ark-One is still statistically outclassed by Zero-Two by a large margin, as well as Horobi Ark Scorpion. However. his reflexes are heightened, allowing him to dodge and parry multiple attacks, and he possesses some of Zero-One Rising Hopper's agility. He also has unique abilities that Zero-One does not possess, enabling Aruto to defeat all of his former allies. Ark-One is able to produce shockwaves of malicious energy from his hand, immobilizing multiple opponents, as well as excrete dark liquid from his feet that melts whatever it touches. He can also reprogram A.I-based technology, allowing him to disable the chips implanted in Isamu and Yua that they require to transform.
Technically while Aruto is using a form connected to the Ark, it carries the risk of making him more aggressive and unable to control his rage. However Ark-One is directly powered by his personal longing to avenge Is's death, causing him to willingly align with the Ark and access As's offer to become Ark-One. The malicious aura that came with the powers constantly keeps Aruto in pain, reflected by his grief and cries; and can even be forced out of his transformation should he use too much power. In later episodes, Aruto shows less strain when using this form, now presumably being able to control it, but the aforementioned mental fallout still affects him. In addition, Ark-One indirectly caused Zero-Two, a form that is linked to There, to gain a tiny fraction of its malicious power. Aruto no longer has this weakness, as his Ark Driver and Ark-One Progrisekey was destroyed by Horobi, returning him to his former glory.
While Ark-One normally fights while unarmed, he briefly wielded the Progrise Hopper Blade during his final fight with Horobi, as well as the numerous Attache Blades scattered around the battlefield.
Kamen Rider Ark-One consists of the following parts:
*: The head.
**: Ark-One's face armor. It is equipped with an ultra-high-performance antenna and a visual/auditory device that are premised on AI processing. The shape is designed and constructed based on the prediction of psychological effects on the person facing the person.
**: The voice information collection device. In addition to the auditory sensor that boasts a sound collection range of 10 km in radius, it will collect voice data from communication devices such as mobile phones and AI-equipped devices such as Huma Gear by entering the network. By filtering the collected data, any sound can be extracted and heard.
**: The right compound eye. It is a collection of image sensors of different methods in a compound eye shape. By combining with image processing, various information such as thermography and X-ray photography can be extracted.
**: The video information collection left eye. By infiltrating the network, it collects video data from reconnaissance satellites, security cameras in the facility, AI-equipped devices such as Humagear. As a result, every place can have its own field of view.
**: The antenna. The smart antenna that changes the directivity according to the environment and can simultaneously send and receive a huge amount of multiple types of information, such as communication with various electronic devices and radar functions, is adopted. Hacking to various electronic devices is executed from here.
**: The control device for the Ark-One system. By manipulating the EEG, the wearer's non-malicious feelings are calmed down, and the consciousness is focused. In addition, the operating efficiency and malfunctions of the wearer's body are checked, and adjustments are made as needed to bring out the limits of functionality.
*: Ark-One's chest armor. It has the function of converting the malicious intent of the wearer into force and generating the wave of malicious intent. Spite negatives cause explosive destruction by emanating from the red line across the front.
*: Ark-One's suit. The liquid metal released from the Ark Driver-One is formed by wrapping up the wearer. Fluid metal is enclosed in a special fabric with excellent toughness and wear resistance, and it functions as armor while maintaining flexibility.
*: Ark-One's upper-arm armor. The fluid metal, which is the main material for the armor, transforms into a sharp shape called by temporarily increasing hardness and density and becomes a piercing weapon.
*: Ark-One's arms. The power cable of the powered suit "Shredding Tector" is stretched around like a human nerve, and reinforces the movement of the wearer from the outside. At the same time, by injecting the energy supplied from the Ark Driver-One, the wearer is given the power to destroy the target.
*: Ark-One's hand and forearm armor. The sharp armor of the fingertips uses the barrier developed from the Ark-One Cuis on the thigh, and manipulates the repulsive force and attractive force on the target to deprive everything of freedom. In addition, the irradiation shaping machine is equipped on the palm, and in addition to materializing various data such as attach weapons with a modeling beam, it also functions as an irradiation port for the "Spite Nega".
*: Ark-One's thigh armor. The is built in and forms a coulomb barrier generated by manipulating electric charges on the armored surface of the whole body. This allows the physical attack to be dispelled by repulsive force.
*: Ark-One's shin armor. By using the barrier developed from the Ark-One Cuisses on the thighs, the repulsive force and attractive force applied to itself can be manipulated to enable floating in the air and maneuver speed.
*: Ark-One's boots. When the Special Move is activated, by expanding the anti-annihilation field, it is possible to convert the substance that becomes a resistance or obstacle into energy. This nullifies the physical defenses and at the same time improves the destructive power of the kick.
Ark Driver finishers:
*:
**: Ark-One's body is surrounded by malicious kanji and yellow electricity before generating two large "wings" of crimson energy. Ark-One then absorbs the energy into his body and projects a red energy field around him. Finally, an explosion destroys anything within the bounds of the energy field and damages anyone nearby.
**: Ark-One jumps into the air and delivers a flying kick covered in red and black energy. Additional black energy is then channeled into his foot just before he strikes the enemy.
Progrise Hopper Blade finishers:
*: Ark-One swings the Progrise Hopper Blade, launching a jagged construct of Cluster Cells at the enemy.
Appearances: Zero-One Episodes 42-45, Gotchard Episodes 34-35

==Notes==
*Ark-One's chest resembles the ZAIA Spec, and by extension the Ark Spec found in the Ark-One Progrisekey.
*While Aruto would become Ark-One, early promotional pictures featured in the Televi-Kun magazine had edited several stock pictures of Kamen Rider Zero-Two to make it appear as if he was fighting Ark-One as well. In Ganbarizing, Ark-Zero was seen transforming directly into Ark-One, while doing a pose similar to As' signature one and lacks voice clips.
**This may have been in line with the original plans of the series, where Ark-One was initially planned to be a separate entity, until changes in the production resulted in Ark-One's identity being changed to Aruto himself.
**Eventually, the physical battle between Ark-One and Zero-Two would be featured in episode 34 of Kamen Rider Gotchard, though both with different users. The process of directly transform from Ark-Zero into Ark-One also have televised debut in Gotchard.
*The undersuit for Ark-Zero and Ark-One was repurposed into Kamen Rider Zaia and later Kamen Rider Thousand Ark in Kamen Rider Outsiders. Likewise, Ark-One's suit in Kamen Rider Gotchard retains the suit modifications from the Kamen Rider Thousand Ark suit, and also retains the black line above the right eye from Kamen Rider Ark-Zero-One.
