"We will destroy you all."
―MetsubouJinrai's first words[src]

Kamen Rider MetsubouJinrai (仮面ライダー滅亡迅雷, Kamen Raidā MetsubōJinrai) is a central character of Zero-One Others. It is the fusion of the four members of MetsubouJinrai.net (Horobi, Naki, Jin, and Ikazuchi) as a result of their corruption by the Massbrain System (マスブレインシステム, Masuburein Shisutemu).

Components[]

MetsubouJinrai was a product of the Massbrain System. Initially, the Massbrain System only consisted of Sold Humagears. However, because of Sold0/Jin's connection with the rest of MetsubouJinrai.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 MetsubouJinrai'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 developed by ZAIA Enterprise under the direction of Lyon Arkland. It served as the primary network system of the Sold Humagears, which removed them them of their free will. As such, they were not allowed to act outside of their original derivatives unless they were forcibly disconnected from it. After Jin was destroyed by Aruto Hiden for the first time, his data was secretly backed-up into the Massbrain System. Lyon intended for the Massbrain System and the Sold Humagear to be expendable tools that could be easily mass-produced for military warfare.

MetsubouJinrai Birth

The birth of Kamen Rider MetsubouJinrai

Through the MetsubouJinrai Driver and Massbrain Zetsumerisekey, Lyon Arkland instigated the the four members of MetsubouJinrai.net into the Massbrain System for his own agenda. Because of Jin's heart for justice, he along with Horobi, Naki, and Ikazuchi were able to temporarily override the Massbrain System's derivatives to unite as Kamen Rider MetsubouJinrai. Despite them defeating the Sold Magia, the group lost control of their free will during the battle against Kamen Rider Zaia, only to dematerialize back into its mental components before any further harm is done.

The four members of MetsubouJinrai later resolved themselves to fuse again to liberate the Solds from the Massbrain System. However, the form engulfed all four's consciousnesses and seemingly deleted them. As a result, Kamen Rider MetsubouJinrai violently turned hostile against Lyon Arkland and slew him in battle. While Isamu Fuwa angrily demanded why they would do this, MetsubouJinrai proceeded to destroy its original selves' bodies before destroying the ZAIA Enterprise Japan building. Kamen Rider MetsubouJinrai was last seen in the rubble of ZAIA Japan's headquarters, where the consciousnesses of Jin, Horobi, Naki, and Ikazuchi started breathing heavily, and screamed in agony over their helpless situation.

Zero-One Others: Kamen Rider Vulcan & Valkyrie[]

Following the destruction of ZAIA Enterprise Japan, Kamen Rider MetsubouJinrai proceeded to target Yua Yaiba. While Kamen Riders Vulcan and Valkyrie engaged the runaway Rider, it destroyed Fuwa's Shotriser in battle. Forced with no other option, Yaiba used the Serval Tiger Zetsumerisekey and assumed Valkyrie Justice Serval to fight MetsubouJinrai as it entered A.I.M.S. base. While she succeeded in damaging the power unit in the MetsubouJinrai Driver, Yua's Shotriser was damaged and she herself was put in critical condition. Kamen Rider MetsubouJinrai then headed to the old MetsubouJinrai hideout to repair its belt and repair the damage inflicted by Yua onto its power unit.

On the way, it encountered Isamu Fuwa in Daybreak Town, who took responsibility in stopping it as he used the Hiden Zero-One Driver and Dire Wolf Zetsumerisekey. Kamen Rider MetsubouJinrai engaged Kamen Rider Vulcan Lone Wolf in a fierce battle, with its conclusion resulting in Kamen Rider MetsubouJinrai's destruction, which vaporized the data of the MetsubouJinrai.net members in the process. Following MetsubouJinrai's death, the remaining Solds were freed from the Massbrain System's influence.

Personality[]

Due to the Massbrain Zetsumerisekey uniting the consciousness of all four MetsubouJinrai.net members into a single feral mass, the resulting collective entity contains no trace of any of its components' personality traits. Instead, it has manifested some form of savior complex, believing that mutual destruction of both MetsubouJinrai.net and ZAIA Enterprise will ultimately save the world, despite the extreme collateral damage it will inflict onto society in the process.

According to Lyon Arkland, Kamen Rider MetsubouJinrai 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.

"(Enemy name) will be extinct!"
―MetsubouJinrai's proclamation[src]
ZAIA will be extinct

"ZAIA will be extinct!"

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

Its dialogue is also accompanied by stylized Japanese translations. For example: ZAIA will be extinct. (ザイアは滅亡する, Zaia wa metsubou suru)

Kamen Rider MetsubouJinrai (仮面ライダー滅亡迅雷, Kamen Raidā MetsubōJinrai) is the fusion form of Kamen Riders Horobi, Naki, Jin, and Ikazuchi, accessed when all four members insert Massbrain Zetsumerisekeys into each of their MetsubouJinrai Drivers within Massbrain, with the physical Zetsumerisekey and Driver being worn by Jin. 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. As the collective entity formed from all four members of MetsubouJinrai.net, the Rider form can access their arsenal, including Horobi's Attache Arrow and Naki's Nihon Ookaminotsume.

This form has two finishers:

  • Massbrain Impact (マスブレインインパクト, Masuburein Inpakuto): Magenta energy wires appear in front of MetsubouJinrai and transfer to their arm, which is then covered in purple energy while a purple wire diagram appears behind them. MetsubouJinrai then delivers a punch to the enemy, with more energy wires appearing upon impact.
  • MetsubouJinrai Impact (滅亡迅雷インパクト, MetsubōJinrai Inpakuto): This finisher has three variations:
    • MetsubouJinrai performs a flying kick covered in purple energy that produces a sonic boom and leaves behind sections of MetsubouJinrai.net's emblem. When the kick strikes the target, the pieces line up, forming the full image.
    • MetsubouJinrai charges their fist with with purple energy before delivering an uppercut to the opponent that produces separated pieces of the MetsubouJinrai.net emblem upon impact
    • MetsubouJinrai 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.

Its suit actor is Yuya Nawata, who served as suit actor for the titular rider and Kamen Rider Ark-One in the series.
