What are some interesting plot ideas for kamen rider dark decade fanfiction?

In a Kamen Rider Decade Crossover Fanfiction, Decade could end up in a world where the Kamen Riders are all children. He has to protect them from an evil force that wants to use their power before they fully understand it. This would involve him teaching them how to use their Rider powers in a more creative and simple way. He could also cross over with a classic monster movie world, like Godzilla's world. Decade and the Kamen Riders have to work together with the monsters to stop an even greater threat.

One interesting Kamen Rider Decade fanfiction could be about Decade traveling to different Rider worlds and teaming up with alternate versions of himself. For example, he might meet a younger version of himself in the Kuuga world and they have to work together to defeat a new, powerful enemy that is threatening all Rider worlds.

Another antagonist could be a group of Kamen Riders from different timelines who see Dark Decade as a threat to the stability of the multiverse. They might band together to stop him, even if he has good intentions in the fanfiction's plot.

A cool crossover idea in this fanfiction could be the exploration of different dimensions. Since Decade can travel through various worlds, he could take Naruto to different dimensions within the Naruto universe that are otherwise unknown or hard to access. They could discover new types of chakra or even meet alternate versions of the ninja characters. In terms of combat, Naruto could teach Decade some ninja techniques like the Rasengan, while Decade could show Naruto how to use his Rider Cards more effectively in battle. This exchange of skills would make their battles against common enemies more exciting and unpredictable.

Another plot could involve Cronus teaming up with a former enemy to face a greater threat. This would force him to re - evaluate his relationships and motives. For example, he might have to work with a Kamen Rider he once tried to destroy. It could lead to some great character development for him.

One idea could be a story where Kamen Rider Phantom has to team up with an unexpected ally from a different dimension. This ally could bring unique powers and a different perspective, creating new challenges and adventures for Phantom.

Another plot could involve Kamen Rider Gaim getting trapped in a time loop. He has to relive the same day over and over again, each time trying to figure out how to break the loop while also dealing with the day - to - day threats he usually faces. In the process, he discovers new things about his powers and the true nature of the threats in his world.

A crossover with Kamen Rider Zi - O could also be really cool. Zi - O travels through time, so he could accidentally disrupt the timeline in a way that affects Ghost's world. Ghost might have to team up with Zi - O to fix the timeline while also dealing with the enemies that are taking advantage of the time - chaos. They could encounter different versions of themselves from alternate timelines and have to figure out how to make things right.

One interesting plot idea could be Chalice crossing over with another Kamen Rider series, like Kamen Rider Decade.
