;Rider Statistics
*Rider Height: 196.0 cm
*Rider Weight: 122.4 kg
;Ability Parameters
*Punching Power: 47.6 t
*Kicking Power: 96.3 t
*Maximum Jump Height: 73.1 m
*Maximum Running Speed: 100 m per 0.8 seconds
Upon being fully revived, the Ark can possess a Humagear host and transform into Kamen Rider Ark-Zero by using the Ark Driver-Zero alone.
Overall, Ark-Zero's stats surpass all Kamen Riders up at the time of his appearance, though Zero-One MetalCluster Hopper still has a higher jump height and his kicking power is also slightly lower than RampageVulcan.
In addition to his own abilities, Ark-Zero can also access the abilities of his host, such as exploiting Ikazuchi's connection with Zea. As revealed in Episode 40, the Ark doesn't need a host to stay in this form, as he maintained his Rider form after Zero-Two ejected him from Ikazuchi. However, this makes him vulnerable to being destroyed without his attacker having to worry about destroying the host as well.
Kamen Rider Ark-Zero is composed of the following parts:
* - The helmet.
**: The face armor. It is equipped with an ultra-high-performance antenna and a visual/auditory device that are premised on AI processing. As for the shape, the minimum elements as a Kamen Rider are extracted based on statistical data, and rearranged efficiently.
**: The visual device on the right side. 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 image information collection device on the left side. By invading 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 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 Humagear by entering the network. By filtering the collected data, any sound can be extracted and heard.
**: The single antennae. The directionality is changed according to the environment, and a smart antenna that can simultaneously send and receive multiple types of enormous information, such as communication with various electronic devices and radar function, is adopted. In addition to hacking various electronic devices from here, human control is performed using special interference waves that manipulate brain waves.
**: The red gem on the forehead, which serves as the control device for the Ark-Zero system. The forced interruption program checks the operating efficiency and malfunctions by intervening in the control system of the Humagear under control, and makes adjustments as necessary to bring out the limits of the functions.
*: The chest armor. It possesses the and the that can penetrate into various devices with excellent penetrating power, allowing it to create a bypass path with a controlled Humagear. As a result, the efficiency of information transmission and the energy flow rate can be increased to enhance the function of the Humagear from the inside.
*: The powered bodysuit. Similar to Kamen Rider Zero-One's MetalCluster Hopper "Amalgamate Tector", the Zero Tector is formed by enclosing the target with liquid metal released from the Ark Driver-Zero. The special metal possesses excellent toughness and wear resistance is filled with fluid metal as it is, and functions as armor while maintaining flexibility.
*: The shoulder armor. One miniaturized particle accelerator is mounted on each shoulder. Each group shares the nuclei and electrons, accelerates to sublight speed, and supplies them to the "zero hand gear" of the hand part to form a part of the heavy charged particle cannon.
*: The arms. It possesses the power cable from the Zero Tector is stretched around like a human nerve, and forcibly controls the arm of the Humagear from the outside. As a result, it becomes possible to exhibit high motility that exceeds the potential of the Humagear placed under control.
*: The gloves. The sharp armor of the fingertips has the function of generating attractive force by partially reversing the barrier deployed from the "Zero Thigh Gear" of the thigh, and strongly adsorbing all objects. Also, the irradiation shaping machine is equipped on the palm, and various data such as attach weapons are materialized by modeling beam. In addition, this irradiation port can be used as a part of a heavy charged particle cannon that emits in a beam shape by synthesizing electrons and nuclei supplied from the Zero Shoulder Gear.
*: The thigh armor. An energy barrier generator 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.
*: The legs. The power cable "M-string" of the powered suit "Zero Tector" is stretched around like a human nerve, and forcibly controls the leg of the Humagear from the outside. This makes it possible to activate a special move that boasts an astonishing destructive power that exceeds the potential of the Humagear placed under control.
*: The shin armor. The internal energy condenser has the role of temporarily storing the energy supplied from Ark Driver-Zero when activating a special move, and discharging a large amount of energy at once.
*: The boots. When the Special Move is activated, the anti-annihilation field can be expanded to convert the substance that becomes a resistance or obstacle into energy. This invalidates the physical defenses and at the same time improves the destructive power of the kick.
Kamen Rider Ark-Zero's finisher is the , which has eight variations:
*Ark-Zero delivers an upward kick covered in red energy.
*Ark-Zero channels red and black energy into his fist and punches the opponent.
*Ark-Zero leaps into the air before channeling red and black energy into his leg and delivering a flying kick to the opponent. 
*Ark-Zero paralyzes the opponent with malicious kanji before telekinetically raising them into the air within tendrils of liquid metal. He then raises his arm and closes his fist, causing the liquid metal to explode along with the opponent.
*Ark-Zero leaps into the air before channeling red and black energy into his leg and delivering a flying side kick to the opponent.
*Ark-Zero paralyzes the opponent with malicious kanji before channeling red and black energy into his his leg and delivering a flying kick to the opponent.
*Ark-Zero raises his arm and forms a large sphere of red and black energy, which he throws at the opponent.
*Ark-Zero stomps on a opponent lying on the ground, before channeling red energy into his his leg, the energy paralyzes the opponent with malicious kanji while the opponent stands up, he then delivering a slash with ZAIA Slashriser that covered in red and black energy to the opponent, before flew over them and land on the ground.

==Notes==
*Ark-Zero's design is heavily modified from Zero-One Rising Hopper.
*During its appearance in Kamen Rider Outsiders and in Kamen Rider Gotchard, Ark-Zero's undersuit and leg armor is reused from Kamen Rider Lucifer, except with the white lines on the thigh armor removed. This is due to the original undersuit being used for Kamen Rider Thousand Ark in the same series. The lower arms, meanwhile, have retained their coloring from when they were repainted for Kamen Rider Zaia, while the original boots are retained too.
