Some interesting concepts can be exploring the backstories of the characters more deeply. For example, what Kenai was like as a child before the events of the movie. Another concept could be alternative endings, like if Kenai had not been turned into a bear and how that would have changed the relationships in the story.
In Brother Bear fanfiction, a cool concept is exploring the relationships between the bears in more detail. How they communicate, their social hierarchies, and how Kenai fits into all of that as a human - turned - bear. Some stories might also focus on the changing seasons and how it affects the bears' lives, adding a touch of realism to the fictional world.
Well, one concept is the expansion of the spirit world aspect. Fanfiction might delve into different spirits and their roles in the lives of the characters. Also, there could be crossovers with other similar-themed stories, which would bring in new elements and interactions. It could make the world of Brother Bear even more complex and fascinating.
One idea could be a crossover with 'Frozen'. Brother Bear's Kenai could meet Elsa and they could learn from each other's experiences with magic and transformation. Elsa could help Kenai understand his own new form better, and Kenai could teach Elsa about the spirits in his world.
One idea could be exploring Nita's life before she met Kenai in more detail. Maybe her relationship with her family and how it shaped her. Another could be a fanfic where Nita has an adventure on her own, facing challenges that test her courage and wisdom. For example, she could be on a journey to find a special herb to heal a sick animal in the forest.
Well, one interesting concept could be the unique relationships that the little brother character forms within the RWBY universe. It might add a new dynamic to the pre - existing teams and friendships.
One interesting storyline could be the bears going on a big adventure in the forest. Maybe they discover a hidden cave full of ancient bear artifacts. Brother Bear could be the brave one leading the way, while Sister Bear uses her wits to solve puzzles they encounter.
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.
Well, in prey fanfiction, a cool concept is the creation of new powers or abilities for the characters. For example, the protagonist could gain some sort of psychic ability related to the alien technology. Some fanfics also delve into the idea of different endings to the Prey story, like a more positive or more tragic end compared to the original. And then there's the concept of crossovers, where Prey characters interact with characters from other science - fiction universes.
In ppg fanfiction, a cool concept is the idea of the Powerpuff Girls forming alliances with other characters from different shows or universes. This could lead to some really exciting crossovers and new storylines. Also, some fanfictions might focus on the origin story of the villains in the Powerpuff Girls world, like how Mojo Jojo became the way he is. And there could be fanfictions that explore the relationship between the Powerpuff Girls and their creator, Professor Utonium, in more depth, like how they feel about being created in a lab.
One interesting concept could be exploring the moral dilemmas that characters face during the purge. For example, a character might have to decide whether to save a stranger or protect their own family. Another concept could be how different social classes experience the purge. The rich might have more resources to protect themselves, while the poor are more vulnerable.
One interesting concept could be alternate universes where the slendytubbies have different powers or characteristics. For example, they might be able to communicate with humans in a friendly way instead of being menacing.
In the sentinel fanfiction, an interesting concept is the world - building. Authors often create a universe where Sentinels and Guides are part of a society that has its own rules and hierarchies. There could be a whole system of training for Sentinels and Guides, and fanfiction may explore how this system works. Also, the relationship between Sentinels and Guides can be seen in different ways, like some stories might focus on the romantic aspect, while others on the platonic or a more mentor - mentee type of bond.
