A kamen rider double crossover fanfiction often combines different kamen rider series, creating unique and exciting storylines. It might bring together characters from various timelines or parallel universes. For example, it could merge the worlds of Kamen Rider W and Kamen Rider OOO. This allows for interesting character interactions, like how the two main riders would team up to fight a common enemy. The crossovers also introduce new forms or power - ups that are not in the original series.
In kamen rider double crossover fanfiction, a prevalent theme is the clash of different fighting styles. For example, the acrobatic and fast - paced fighting style of Kamen Rider Kabuto might contrast with the more brute - force approach of Kamen Rider Gaim. Writers use this to create exciting battle scenes. Additionally, the theme of friendship across different kamen rider worlds is also popular. Riders from different series might form unexpected friendships during the crossover.
Kamen Rider Decade would be an excellent choice. Since Decade can travel between different Kamen Rider worlds, it would be easy to create a story where he and Orga meet and team up. Another good option is Kamen Rider Kuuga. Their different fighting styles and powers could create an interesting dynamic. Also, Ultraman could be a great crossover character. The contrast between the Kamen Rider and Ultraman universes would make for a very exciting story.
One interesting storyline could be where a Kamen Rider gets trapped in the Castlevania universe. He might have to fight the classic Castlevania monsters using his Rider powers. For example, imagine Kamen Rider W facing off against a horde of skeletons and zombies. His unique fighting style and gadgets would make for an exciting battle against the supernatural foes of Castlevania.
Ruby Rose is often a popular choice. Her energetic and determined personality makes her a great candidate to interact with the Kamen Rider characters. She could be curious about their transformation abilities and might try to incorporate some of their techniques into her own combat style.
Well, if Kamen Rider and a Castlevania character combined their abilities, it could be really cool. For instance, a Kamen Rider's speed could be used to quickly dodge the attacks of Castlevania's slow - moving but powerful enemies like the Death monster. And the Castlevania character's weapon skills, say Trevor Belmont's whip skills, could be enhanced by the Kamen Rider's power - up items.
One idea could be a crossover with another Kamen Rider series. For example, Kamen Rider Orga could team up with Kamen Rider Decade. They could travel through different Rider worlds together, facing challenges unique to each world. Another plot could involve a crossover with a popular anime. Maybe Orga has to enter the world of Naruto and fight alongside the ninjas against a common enemy. Or perhaps a crossover with a superhero universe, like the Marvel Universe, where Orga has to join forces with the Avengers to stop an inter - dimensional threat.
Another possibility is Kamen Rider Decade. Decade has the ability to transform into different Kamen Riders, and his presence in a crossover with Kickhopper could bring a lot of different elements into the story. He could use his powers to help Kickhopper access new forms or abilities, or they could travel through different Kamen Rider worlds together to stop a multiverse - level threat.
Well, perhaps the fanfic could revolve around Kickhopper finding himself in an alternate universe where the rules of being a Kamen Rider are different. He has to adapt and form a crossover alliance with a local hero. They start by comparing their transformation devices and learn from each other's fighting styles to defeat a group of interdimensional thieves who are stealing important artifacts from both universes.
Another plot idea is a time - travel crossover. Zero One could be sent back in time to the era of the first Kamen Riders. There, he has to adapt to the different fighting styles and technology of that time. He might also introduce some of his own futuristic technology to the early Kamen Riders, changing the course of their battles and the development of their powers.
