Kamen Rider Hacker

> We will destroy you all.
>
> Hacker's first words, Kamen Rider Proto Zero-One

**Kamen Rider MetsubouJinrai** is a central character of the *Proto Zero-One Others* series. It is a collective yet mindless fusion of the four members of Hacker.net (**Herobe**, **Saki**, **Jen**, and **Hamakaze**) as a result of their corruption by the **Massbrain System**.

## Components

Hacker was a product of the Massbrain System. Initially, the Massbrain System only consisted of Sold Humagears. However, because of Sold0/Jen's connection with the rest of Hacker.net, all four of them managed to connect to the system and override it with their unified will, hence creating the new Rider. The rest of the Solds played a passive role in Hacker's functioning, which was reduced to zero when it severed their Massbrain Zetsumerisekeys from their arms, ejecting them from the Massbrain System.

## History

### Background

The Massbrain System was created by GAIA Enterprise under Daiki Kaido's supervision. It served as the network system of the Sold Humagear, removing them with free will and cannot act outside of their derivative unless forcibly disconnected from the Massbrain System. When Jen was destroyed by Azuma Suzuki for the first time, his data was secretly backed up into the Massbrain System. Daiki Kaido intended the Massbrain System and Sold Humagear to be expendable tools that could easily be mass-produced for war purposes.

### Proto Zero-One Others: Kamen Rider Hacker

Through the Hacker Driver and Massbrain Zetsumerisekey, Daiki Kaido instigated the the four members of Hacker.net into the Massbrain System for his own agenda. Because of Jen's heart for justice, he along with Herobe, Saki, and Hamakaze were able to temporarily override the Massbrain System's derivatives to unite as Kamen Rider Hacker. Despite them defeating the Sold Mester, the group lost control of their free will during the battle against Kamen Rider Gaia, only to dematerializes back into its mental components before any further harm is done.

The four members of Hacker.nett later resolve themselves to fuse again to liberate the Solds from the Massbrain System. However, the form engulfed all four's consciousnesses and seemingly deleted them. Kamen Rider Hacker violently turns hostile against Daiki Kaido and slained him in battle. While Izumi Kaishi angrily demanded why they would do this, Hacker.net proceeds to destroy its original selves' bodies before destroying the GAIA Enterprise Japan building. Kamen Rider Hacker is last seen in the rubble of GAIA Japan's headquarters, where the consciousnesses of Jen, Herobe, Saki, and Hamakaze started breathing heavily, and scream in agony over their helpless situation.

### Proto Zero-One Others: Kamen Rider Vulcan & Valkyrie

Following the destruction of GAIA Enterprise Japan, Kamen Rider Hacker proceeds to target Sakura Mottai. While Kamen Riders Vulcan and Valkyrie engage the runaway Rider, it destroys Kaishi's Shotriser in battle. Forced with no other option, Mottai uses the Serval Tiger Zetsumerisekey and assumes Valkyrie Justice Serval to fight Hacker as it enters B.I.M.S. base. While she succeeds to damage the power unit in the Hacker Driver, Sakura's Shotriser is damaged and Mottai is put in critical condition. Kamen Rider Hacker heads to the old Hacker hideout to repair the belt and fixes the damage Sakura did to the power unit.

On the way, it encounters Izumi Kaishi in Daybreak Town, who takes responsibility in stopping it as he uses the Suzuki Zero-One Driver and Dire Wolf Zetsumerisekey. Kamen Rider Hacker would battle Vulcan Lone Wolf in a fierce battle. As their finishing Rider Kicks collided, Kamen Rider Hacker was completely destroyed, vaporizing the data the four Hacker.net members in the process. Following Hacker's death, the Solds remained released from the Massbrain System's influence.

## Personality

> (Enemy name) will be extinct!
>
> Hacker's proclamation, Kamen Rider Proto Zero-One

Due to the Massbrain Zetsumerisekey uniting the consciousness of all four Hacker.net members into a single feral mass, the resulting Rider does not contain any of the personality traits of its components. Upon its recreation, it has manifested some form of a savior complex, believing that mutual destruction of both Hacker.net and GAIA Enterprise will ultimately save the world, despite the extreme collateral damage that it'll inflict onto society in the process.

According to Daiki, Kamen Rider Hacker represents what the group was, rather than what they're now: the highly destructive terrorists that seek to exterminate humanity for the prosperity of A.I. It demonstrates this through its destructive agenda, refusing to give its four users any say in the matter.

Although it rarely speaks, its main system interface is in English, possibly due to the Massbrain System having been developed at GAIA's United States branch. Humorously, it has a tendency to point at their enemies when speaking.

**Kamen Rider Hacker** is the fusion form of Kamen Riders Herobe, Saki, Jen, and Hamakaze, accessed when all four members insert Massbrain Zetsumerisekeys into each of their Hacker Drivers within Massbrain, with the physical Zetsumerisekey and Driver being worn by Jen. The transformation will then disable all four Humagears and materialize the Rider from their minds.

Due to the nature of the Massbrain Zetsumerisekey, this form is uncontrollable as the fusion creates a singular entity with a unique personality that takes control over the body and quickly suppresses the minds of all four of its users.

This form has two finishers:

* **Massbrain Impact**: Magenta energy wires appear in front of Hacker and transfer to their arm, which is then covered in purple energy while a purple wire diagram appears behind them. Hacker then delivers a punch to the enemy, with more energy wires appearing upon impact.
* **MetsubouJinrai Impact**: This finisher has three variations:
	+ Hacker performs a flying kick covered in purple energy that produces a sonic boom and leaves behind sections of emblem. When the kick strikes the target, the pieces line up, forming the full image.
	+ Hacker charges their fist with with purple energy before delivering an uppercut to the opponent that produces separated pieces of the Hacker.net emblem upon impact
	+ Hacker leaps into the air and performs a downward flying kick covered in purple energy that produces a sonic boom while the MestibouJinrai.net emblem trails behind them. The kick strikes the enemy's Driver, causing it to crack before breaking apart.

## Behind the Scenes

### Portrayal

Kamen Rider Hacker is dual-voiced by both Marvin and Jeff Dickson, who had voiced Proto Zero-One's equipment (except the Ark Driver and Ark-One Progrisekey). Secondary, the Rider was voiced in some scenes and towards the end of the films by Jeremy Perez, Jimmy Hart, Joe Harris, and Noah Carter, who portrayed the four members of Hacker.net that were "absorbed" by the Rider through vocalizations & grunts. Its suit actor is Ryutaro Sakado, who served as suit actor for the titular rider and Kamen Rider Veal-One in the series.
