Definitely. There are many creative fanfictions. One type of story could be where the Avengers are transported to the world of Kamen Rider and have to learn the rules and powers there to get back home. Another could be a reverse situation. The stories often play with the different powers, personalities, and storylines of both franchises, creating new and engaging plots for fans to enjoy.
One idea could be that the Avengers are transported to the world of Kamen Rider Build. They team up with Build to fight a common enemy that has the power to disrupt both universes. For example, a villain who can manipulate matter like Build's powers but on a much larger scale, threatening Earth in the Avengers' world and Build's city in his world.
Often, Iron Man from the Avengers and Kamen Rider Decade are popular. Iron Man's high - tech gadgets and intelligence make for interesting interactions with the unique powers of Kamen Rider Decade. They can both be seen as leaders in their respective groups, so seeing them work together or clash in fanfiction can be really engaging.
Yes, there might be some out there. You can start by looking on fanfiction websites. Some writers might combine the ideals of communism with the heroic and super - powered world of the Avengers in creative ways. However, it's not as common as other types of fanfiction.
There are indeed a few. However, they might not be as mainstream as other Kamen Rider media such as the TV shows or movies. You can try searching on specialized Japanese game or doujinshi (self - published works) websites. Some of them are in Japanese though, so you may need to use translation tools if you're not fluent in Japanese.
Not that I'm aware of. I haven't come across any Kamen Rider visual novels so far.
I really like 'Kabuto in the Hidden Leaf'. In this fanfiction, Kamen Rider Kabuto's character is inserted into the Naruto universe. He has to deal with the politics and challenges of the ninja villages. The author does a great job of showing how Kabuto's powers and his way of thinking contrast with the traditional ninja ways. It's a fresh take on both franchises.
One interesting Kiva fanfiction could be about a new rider who teams up with Kiva to fight an ancient evil that has resurfaced. They might have to combine their powers in unique ways to defeat the powerful foe.
One idea could be creating an OC (Original Character) who is a time - traveling kamen rider. They could go back in time to prevent certain disasters in the kamen rider universe. Another idea is an OC that has a unique transformation device, like a kamen rider who transforms using music notes. For example, their henshin (transformation) sequence could be accompanied by a symphony.
One interesting kamen rider girls fanfiction could be about their training adventures. Maybe they are in a special training camp where they learn new combat skills and also face some challenges within the group. For example, there could be a story where two of the kamen rider girls have a friendly competition to see who can master a new technique first.
One interesting kamen rider reaction fanfiction could be where the characters react to a new and powerful villain. For example, they might be shocked at the villain's unique abilities and have to quickly come up with a new strategy to defeat them.
