Horobi

Horobi (滅) is a rogue Humagear and the leader of the terrorist group MetsubouJinrai.net which, hacks HumaGears and transforms them into Magia with the goal of causing humanity's extinction. Jin carries out his orders.

He transforms into Kamen Rider Horobi (仮面ライダー滅) using the MetsubouJinrai ForceRiser.

History
Horobi is believed to be responsible for the Daybreak Town incident, having caused the town's Humagears to go berserk. As a Kamen Rider, he sent a terrorist video to one of the town's main power plants, revealing the existence of MetsubouJinrai.NET and declaring his war on humanity. In the following years, Horobi set up a base inside the ruins of the town.

Twelve years later, after Korenosuke Hiden's passing, Horobi restarts his crusade against humanity. Horobi seeks Humagears with a near singularity status and forcibly transforms them into Magias with the help of his partner Jin and Zetsumerise Keys.

Horobi resumed MetsubouJinrai.net's activities by sending Jin to hack into Gut Buster Taro, leading to havoc across the amusement park the HumaGear worked at, forcing Aruto Hiden to transformn into Kamen Rider Zero-One to fight the Magia.

When a new Singularity was awakening in Okureru he gave Jin a ZetsumeRise Key to hack into the HumaGear and collect data.

After MetsubouJinrai.net's presence has been made public Horobi showed no concern about Zero-One or A.I.M.S. when questioned by Jin, instead just deciding to focus on the Ark.

When Isamu Fuwa ventured into Daybreak Town and found proof regaring MetsubouJinrai.net's involvement in the accident of twelve years ago, Horobi appeared as Kamen Rider Horobi and destroyed the Trilobite Magia who managed to somehow fight back their hacking, burning the evidence and keeping the Ark's existence hiden.

Back at Daybreak Town, after witnessing Horobi's Kamen Rider form, Jin tells him that he wants a Progrise Key, but is told that what they want is human extinction before Horobi sends him to hack into another HumaGear. After the Vicarya Magia is destroyed he tells Jin to not pursue the Progrise Keys, leading Jin to believe he is just an assistant, however, Horobi reveals that he is Jin's father.

After the revelation Horobi is questioned by Jin about their parent-child dynamic. Horobi explains that he is Jin's father and that children should listen to what their parents say as he grants Jin permission to go after the Progrise Keys.

When Jin returns with the Flying Falcon Progrise Key and questions Horobi about parents needing to protect their children, Horobi is quick to dismiss it and say that Jin is already strong and doesn't need protection, pointing out that their family dynamic isn't a regular one before sending Jin to gather more of Zero-One's Progrise Keys.

When Jin becomes conflicted and shows remorse towards hacking a HumaGear, Horobi appears before him and Zero-One. Initially unintentionally leading Jin to believe he came to protect him, Horobi dismisses it and reveals that Jin is actualy a HumaGear he created, that being the reason he calls him son. Ordering Jin to do what he says Horobi uses the MetsubouJinrai ForceRiser to hack him and override his personality with MetsubouJinrai.net's protocol, forcing him to use the Flying Falcon Progrise Key to transform into Kamen Rider Jin. As the fight starts, Horobi leaves the scene and returns to Daybreak Town, later praising Jin for his good work upon his return.

Horobi stops taking Zero-One lightly after the incident with Jin and introduces a Assassin-Type Humagear, a new Magia capable of becoming stronger as he learns. Horobi gives him the Dodo Zetsumerise Key and orders him to target Zero-One.

Personality
The commanding terrorist leader of MetsubouJinrai.net, Horobi believes that AI systems surpass humanity in every way. He views the destruction of humanity as a crusade, and is focused on a project he refers to as "the Ark". He considers Aruto, who makes laughter his policy, his rival. Quiet and calm, he is ruthless in the lengths he will go to protect his plans.

Unlike Jin, Horobi seems to prefer working in the shadows.

Horobi shows concern towards Jin's safety, initially talking him out of wanting a Progrise Key to transform and eventually telling him to stop pursuing them, saying that he is more valuable than a mere assistant right before revealing himself to be Jin's father.
