What are some interesting plot ideas for 'Crisis on Earth X Crossover Fanfiction'?

Well, in some fanfictions, there might be a plot twist where the portals between the different Earths malfunction in a new way. Instead of just allowing the heroes and villains to cross over, they start merging certain parts of the different Earths. So you might have a city on Earth - 1 that suddenly has a section that looks like it's from Earth - X. This would create all sorts of chaos and new challenges for the characters to deal with. It also gives an opportunity for different versions of the characters to interact in unexpected ways, like a more peaceful version of a villain from one Earth having to face off against their more malevolent counterpart from another Earth that has now invaded their space.

One idea could be that the Ranma characters get transported to the Bubblegum Crisis world. Ranma could be confused by the high - tech setting and the existence of Boomers. Maybe he would initially try to use his martial arts against them, thinking they are just some strange opponents. Another plot could involve the Knight Sabers somehow getting involved in a martial arts tournament in the Ranma world. They would have to adapt to the different fighting styles and rules there.

One idea could be Jedi coming to Earth to train a select group of humans with Force - like abilities. Another could be a Sith Lord arriving on Earth and causing chaos, and Earth's heroes have to team up with Star Wars characters to stop him. Maybe there's a discovery of a hidden Star Wars - related artifact on Earth that has the power to change the balance of the Force.

One idea could be a crossover of characters from different Arrowverse shows on Earth X. For example, having Barry Allen from 'The Flash' team up with Kara Danvers from 'Supergirl' to fight against the evil regime on Earth X. They could use their super - speed and super - strength respectively to take on the powerful foes there.

A great plot idea would be a crossover with 'Game of Thrones'. The political intrigue in both worlds could be merged. Maybe Talion could find himself in the middle of the power struggle between the different houses in Westeros. He could use his skills to either side with a particular house or try to stay neutral while still achieving his own goals in Middle Earth which are now somehow intertwined with the events in Westeros.

A crossover with a modern - day setting could also be really cool. Picture Talion and Celebrimbor suddenly appearing in a big city. They would have to adapt to modern technology while also dealing with an evil force that has followed them through some sort of magical portal. The contrast between their medieval - style combat skills and the high - tech environment would make for some really interesting scenarios.

One idea could be that Godzilla Earth teams up with a group of humans who have developed advanced technology to fight off an alien invasion. The humans initially fear Godzilla but soon realize they need his power.

Perhaps in this fanfiction, Naruto discovers a hidden ability that was passed down from Kushina. They go on a journey together to learn more about this power and how to control it. This would involve a lot of training sessions and some heart - to - heart conversations between mother and son.

One idea could be that Naruto and Hinata end up in an alternate universe where their roles are reversed. Hinata is the loud and confident one, while Naruto is more shy. Another could be a time - travel plot where they go back in time and have to work together to change an important event in the ninja world. They might also find themselves in a world where all the ninja clans have different powers, and they must combine their skills to survive.

One idea could be that Ichigo and Rukia find themselves in an alternate universe where their roles are reversed. Rukia could be the one with the Shinigami powers from the start in Karakura Town, and Ichigo is a normal human who gradually discovers his own latent spiritual abilities to help her. Another could be that they are sent on a special mission together to a realm neither has been to before, like a dimension full of lost souls. There, they have to rely on each other more than ever to find their way back and complete their task.
