Zero

Zero is the main protagonist of Rider Zero-One: Prologue and Kamen Rider: Fake

## Biography

Zero is described as a mechanized cyberframe, essentially a cyborg, that resides within the year of 2021. His main role within the series is to assist the hacker, Mayumi/One, to track down any nearby Shells within cyberspace and destroy them, preventing them from causing a huge disruption in the real world.

## History

### Rider Zero-One: Prologue

At an unspecified point in time, Zero was once a human. However, due to unknown circumstances, his body was in need of medical aid. He would soon be found by Mayumi, who would patch him up, giving him a copy of her own mind. Ever since he was saved, he has no recollection of his past life as a human.

**Kamen Rider: Fake**

Zero returns as the protagonist of Kamen Rider: Fake. An unspecified amount of time has passed for Zero, now older and able to use the Zero-One Driver, he refers to himself as a failure, having failed to protect someone (presumably Mayumi). however, one Shell he encounters retains it's sentience like he did, albeit without a body.

## Personality

Zero is a curious individual who observes and analyzes the things around him. One of the most prevalent things he analyzes are the many facets of the human mind. Many examples include why humans harm one another, what causes conflict, etc. To satisfy his curiosity, he usually asks Mayumi questions. According to himself, Mayumi is one of the most intelligent humans he has ever met.

Despite being half machine, Zero has demonstrated traits of compassion, optimism, and courage. He always expresses worry when Mayumi coughs during their hunts for Shells, advising her to take her medication. There has been a few times when Zero had found himself in conflict with his operator. In times like this, he questions the other if an argument has started or apologizes for not understanding her words, according to his own analysis in Episode 02. Other times, like in Episode 03, he becomes clueless and confused as to why his operator had gone offline in a rage.

During the last two episodes, despite being injured, he refuses to back down from battle as just like any other hero, he cares for the lives of the many.

In Kamen Rider: Fake, Zero is a lot more cynical and nihilistic, constantly referring to himself as a "failure". when a dying shell called him a "Kamen Rider", the human AI, Rose asked him if that's what he was, to which Zero replied: -

"No, I'm a fake."

He helps Rose gain a body of her own, by temporarily letting her control his so they can get a Shell body to use.

At the end of Fake, Zero presumably dies, proving his own points.
