Another concept might be alternate universes. Maybe a Zootopia where predators and prey have completely different social dynamics. They could be living in a more equal yet chaotic world where the roles are not as clearly defined as in the original movie.
One interesting concept could be the exploration of power dynamics in a darker Zootopia. For example, how different species might abuse their power or be oppressed in a more sinister version of the city. It might also delve into the seedy underbelly of the animal society that was only hinted at in the original movie, like illegal activities among certain groups.
One interesting story could be about a new character who comes to Zootopia from a far - off land and has to adapt to the city's unique culture. This new character might bring in new ideas and skills that change the way some of the existing characters view their world.
Perhaps the fanfiction explores different meeting scenarios that were not shown in the original movie. It could show the first meetings of the main characters in a different context, like instead of Judy meeting Nick at the ice cream parlor, they meet during a big city - wide event where there's chaos and they have to rely on each other from the start. This would change the dynamic of their relationship development.
Another interesting concept is an OC that is a street artist in Zootopia. This character could use their art to bring different species together, or perhaps their art is a form of protest against some of the underlying prejudices in the city. They could interact with the known characters like Judy Hopps and Nick Wilde, adding a new dimension to the story.
Some dark zootopia fanfiction might also focus on the psychological toll of living in a society that seems so perfect on the surface but has hidden problems. Characters could struggle with depression or anxiety, like Judy Hopps realizing that her dream job isn't all she thought it would be and having to deal with the corruption and darkness she discovers within the Zootopia Police Department.
A great Zootopia crossover fanfiction idea is with the world of Avatar. The animals could visit Pandora and interact with the Na'vi. The Na'vi might be fascinated by the talking animals from Zootopia. Or a crossover with the Incredibles. The super - powered family could team up with Judy and Nick to solve a crime in Zootopia that involves some super - villainous animal. Also, a crossover with Toy Story where the Zootopia toys come to life and have their own adventures within the city would be really fun.
One interesting Zootopia human fanfiction could be about a human detective who has to solve a mystery in a world where animals have human - like intelligence and society. He might face challenges in understanding their unique cultures and ways of communication.
A great abdl zootopia fanfiction could be centered around an older animal taking care of a younger one with abdl traits. In Zootopia, with all its different species and cultures, this could be a really heartwarming story about the bond between the two characters, and how they grow together while also showing the diversity and inclusiveness of the Zootopia world.
A human journalist could visit Zootopia to write a story about the city. But during their stay, they uncover a conspiracy that threatens the harmony between the different species. The journalist then teams up with a fox like Nick Wilde to expose the truth. This would be a great way to explore the politics and social structure of Zootopia from a human's perspective.
Maybe a wolf OC who is a teacher in Zootopia. This wolf could teach self - defense classes to smaller animals, but has to deal with the fear and prejudice some of the students' parents have. It could be about how the wolf overcomes these obstacles and builds trust within the community.
