* Niku
* Ark-Zero

**Niku** (憎, *lit. Hatred*) formerly known as **Kagayaku** (輝く, *lit. Sparkle*) is a member of MetsubouJinrai.net and is the co-leader of a squad of Humagears as **Kamen Rider Niku** (仮面ライダー憎, *Kamen Raidā Niku*, lit. Masked Rider Hatred). However, his disloyal allegiance to the Ark was exploited by the satellite, who possessed and used Niku's body as a host of **Kamen Rider Ark-Zero** (仮面ライダーアークゼロ, **Kamen Raidā Āku Zero**).

## History

### Origin

Niku was originally a Janitor-Type HumaGear named Kagayaku who was suppose to be used by LimeSoft Studios before getting taken by Horobi. During the Daybreak Town Accident, Miku, alongside Kura, Ita, Ensa, Gokusha and Besshi, was hacked by the newly activated Ark; he thus became a member of MetsubouJinrai.net, with their goal to wiping out humanity aligning with the Ark's own.

### First Move

Niku starts to act after the death of Korenosuke Hiden. He starts to collect materials to provide Zetsumerisekeys.

### Syncnet's Bidding

Kura and his team were tasked to work with Syncnet despite his disapproval of the organization.

## Movies and other events

### Dream Riders x Dream Sentai: New Generation

Niku is one of participating Kamen Riders as part of the All Riders fighting for his own and everyone's existence. Dream Riders x Dream Sentai: New Generation

## Abilities

* **Cognitive Learning**: Instead of powering up his Rider Form to catch up to his foes, Horobi can learn his opponents' fighting patterns and adapt it to his own skills, allowing him to (at least) weaken or defeat opponents with the likes of Thouser and Zero-One Shining Hopper. However, this skill still has its limits, as Thouser can retaliate back.

Niku transforms into Kamen Rider Ark-Zero using the Ark Driver-Zero after being possessed by the Ark.

In this form, Ark-Zero's stats surpasses all Kamen Riders up till his appearance, but Zero-One MetalCluster Hopper still outclassed him in terms of maximum jump height. In addition, his kicking power is also slightly lower than RampageVulcan. Compared to his fellow followers, he is the strongest among them.

It is weaker compared to when he possessed Horobi at the moment, but is as strong as its original host an episode later. However, due to Niku's willpower, it can make Ark-Zero paralyzed for a short while.

Kamen Rider Ark-Zero is composed of the following parts:

* **Ark-Zero Head** (アークゼロヘッド, *Āku Zero Heddo*) - The helmet.
	+ **Zero Face** (ゼロフェイス, *Zero Feisu*): 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.
	+ **Eclipse Eye** (エクリプスアイ, *Ekuripusu Ai*): 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.
	+ **Zero Face Vision** (ゼロフェイスビジョン, *Zero Feisu Bijon*): 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.
	+ **Zero Face Ear** (ゼロフェイスイヤー, *Zero Feisu Iyā*): 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.
	+ **Zero Face Antennae** (ゼロフェイスアンテナ, *Zero Feisu Antena*): 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.
	+ **Ark Signal Zero** (アークシグナル ゼロ, *Āku Shigunaru Zero*): The red gem on the forehead. A control device for the Ark-Zero system. The forced interruption program **"Prisonment Chain"** (プリズメントチェイン, *Purizumento Chein*) checks the operating efficiency and malfunctions by intervening in the control system of the human gear under control, and makes adjustments as necessary to bring out the limits of the functions.
* **Zero Chest Gear** (ゼロチェストギア, *Zero Chesuto Gia*): The chest armor. It possesses the **Worm Terminal** (ワームターミナル, *Wāmu Tāminaru*) and the **Restraint Cable** (リストレントケーブル, *Risutorento Kēburu*) 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 human gear from the inside.
* **Zero Tector** (ゼロテクター, *Zero Tekutā*): 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 Arc 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.
* **Zero Shoulder Gear** (ゼロショルダーギア, *Zero Shorudā Gia*): 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.
* **Marchinis Arm** (マーキニースアーム, *Mākinīsu Āmu*): The arms. It possesses the power cable **"M string"** (Mストリング, *M Sutoringu*) from the Zero Tector is stretched around like a human nerve, and forcibly controls the arm of Huma Gear from the outside. As a result, it becomes possible to exhibit high motility that exceeds the potential of the human gear placed under control.
* **Zero Hand Gear** (ゼロハンドギア, *Zero Hando Gia*): The gloves. The sharp armor of the fingertips **"Spite Nail"** (スパイトネイル, *Supaito Neiuru*) 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 **"Beam Equipper"** (ビームエクイッパー, *Bīmu Ekuippā*) 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.
* **Zero Thigh Gear** (ゼロサイギア, *Zero Saigia*): The thigh armor. An energy barrier generator **"Coulomb Generator"** (クーロンジェネレーター, *Kūron Jenerētā*) 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.
* **Marchinis Leg** (マーキニースレッグ, *Mākinīsu Reggu*): 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 human gear from the outside. This makes it possible to activate a special move that boasts an astonishing destructive power that exceeds the potential of Huma Gear placed under control.
* **Zero Shin Gear** (ゼロシンギア, *Zero Shin Gia*): The shin armor. The internal energy condenser **“Zero Annihilator”** (ゼロアナイアレイター, *Zero Anaiareitā*) has the role of temporarily storing the energy supplied from Arc Driver-Zero when activating a special move, and discharging a large amount of energy at once.
* **Zero Foot Gear** (アークゼロヘッド, *Zero Futto Gia*): 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 **All Extinction** (オールエクスティンクション, *Ōru Ekusutinkushon*):

* 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.
