The Multiverse, a term given to the group of parallel worlds, dimensions, realities, realms, or universes. And, in one of these dimensions, known as Dimension-1218 (also known as the “Real World”), this “Multiverse Theory” has never been actually proven true. That is, until an autistic 19 year old boy named Nick Brown, who just graduated from high school a year late due to the Covid-19 Pandemic, discovers a mysterious, yet familiar-looking, pocketwatch. Now, Nick must use his newfound powers to fight enemies from other dimensions, while also traveling to these alternate worlds, as the new Defender of Worlds, and successor of the Destroyer of Worlds. And, maybe, also find a world where he’ll find a sense of belonging. He’s just a passing through Kamen Rider, remember that!

Disclaimer: I do not own Kamen Rider Decade, nor any other Kamen Riders. I also don’t own any other characters and/or series that will/may appear in this story. Also, I will be censoring any inappropriate language and context in this story.

Here, I'm going to show some important villains in this story.


Backstory: An evil organization that invades other parallel worlds with the Aurora Curtain. They can copy the powers of Kamen Rider through their advanced technology, allowing their members to transform into them. After the deaths of the Hundred Four, Hundred began to create monsters called "Another Riders". Razen formed an alliance with them to hunt Nick across the Multiverse. The Hundred Four also get revived by the Hundred Superiors to kill Nick.


Villain Name: Kamen Rider Ark-Zero/Ark-One.


Backstory: Kamen Rider-based monsters that Hundred created to serve them in invading other dimensions. They can only be destroyed by someone who can either transform into the respective Kamen Rider that the Another Rider is based on, or someone who can access a form based on the respective Kamen Rider.
