A time - travel based concept in disney princess crossover fanfiction is really exciting. Let's say Aurora is sent into the future and meets Rapunzel in her tower. Aurora could be amazed by Rapunzel's long hair and Rapunzel could be in awe of Aurora's enchanted sleep story. Or, a crossover where the princesses swap kingdoms for a day. Mulan would have to deal with the courtly manners in Ariel's underwater kingdom, while Ariel would have to face the challenges of leading an army in Mulan's world.
One interesting concept could be a crossover where the princesses from different eras meet. For example, Snow White from the earliest Disney princess era meeting Moana. They could exchange their stories of courage. Snow White could learn about Moana's journey across the ocean, and Moana could be inspired by Snow White's kindness in the face of danger. Another concept might be a magic - related crossover. Like all the princesses coming together to solve a magical mystery that threatens their kingdoms. They could combine their unique magical abilities, such as Cinderella's fairy godmother - like transformation magic and Elsa's ice magic to overcome the problem.
One interesting concept could be the Cars characters interacting with characters from other Disney movies. For example, Lightning McQueen meeting Mickey Mouse. It would be a really fun and unexpected crossover. Maybe they could have a race together, with Mickey cheering on Lightning McQueen from the sidelines.
Well, a great concept might be the appearance of Star Wars' iconic spaceships in the Disney universe. Imagine the Millennium Falcon flying over the landscapes of a Disney - like fantasy world. It would be a sight to behold. And also, the characters from both universes could embark on adventures together, like Han Solo and Mickey Mouse teaming up to save both their worlds from a common threat.
One interesting concept could be how the reincarnated OC retains some of their past life's memories. For example, they might remember a certain Disney character they were related to in their previous life and use that knowledge to navigate the new Disney - inspired world. It adds an element of mystery and connection to the Disney universe.
Some fanfictions play with the idea of the princesses being villains themselves. Belle could use her intelligence to manipulate those around her instead of being the kind - hearted book - lover. And Jasmine might be a power - hungry princess who will stop at nothing to gain more control over her kingdom, rather than just wanting to escape the arranged marriage.
One interesting concept could be the clash of different mythologies. For example, if Nyarlathotep were to cross over with Norse mythology, the chaos he represents could disrupt the order of the Nine Worlds. Another concept might be the interaction between Nyarlathotep and modern-day characters. It could explore how an ordinary person would react to the presence of such a malevolent entity from Lovecraftian lore. Also, the idea of Nyarlathotep influencing different historical events in a crossover fanfiction can add a new layer of depth, like how he might have affected the fall of the Roman Empire in a fictional scenario.
One interesting concept could be the combination of different alien species from various sci - fi universes with the Space 1999 setting. For example, mixing the Goa'uld from Stargate with the Moonbase Alpha crew. It could create really unique power dynamics and storylines.
One interesting concept could be Momonga in a different game world, like being transported to a fantasy RPG world. He might use his unique skills from the original setting to survive and thrive there.
One interesting concept is the collision of different character personalities. For example, when a heroic character from one universe meets a morally ambiguous one from another. Another is the exploration of different power systems. How would a magic - based character fare against a technology - driven one? Also, the cultural clashes can be fascinating. Different universes might have unique social norms and values, and seeing how characters adapt or react to these differences can create engaging storylines.
In Avatar 2009 crossover fanfiction, a cool idea is a crossover with a post - apocalyptic setting. The Na'vi could be faced with the challenges of a world destroyed by humans in a different way. They might have to deal with new threats and also learn from the survivors of the apocalypse. Also, a crossover with a superhero universe could be fascinating. Picture the Na'vi getting superpowers or having to deal with superheroes coming to Pandora.
One interesting concept could be a crossover with the Men in Black. Imagine the Ghostbusters teaming up with the MIB agents to deal with paranormal entities that are also of alien origin. They would have to combine their different technologies and ways of handling the supernatural and extraterrestrial.
