Another plot could be a 'what - if' scenario. What if Moana had the ability to see the spirits like in Coco? How would that change her story? Maybe she would have to deal with some angry spirits on her journey that she could only see and communicate with because of this new ability. This would add a whole new layer of conflict and adventure to her original story.
One common plot idea could be a crossover where characters from Coco end up in the world of Moana. For example, Miguel could meet Moana and they could go on an adventure together, perhaps using Miguel's music skills and Moana's sailing expertise to solve a new problem in Moana's world.
One idea could be an OC who is a long - lost relative of Moana. This OC could have been separated from the family during a great storm years ago. They could have unique skills, like being able to communicate with a different type of sea creature that Moana has never encountered. This would bring new adventures as Moana and the OC try to figure out how this new discovery could help their island.
Maybe the OC is from a different island and Keoni helps her adjust to life on Moana's island. Along the way, they fall in love. There could be cultural clashes and misunderstandings at first, but as they get to know each other better, they bridge the gaps between their two cultures.
One idea could be that Ruby and Coco team up for a special mission in a dangerous, uncharted part of Remnant. They face new Grimm and have to rely on each other's unique skills to survive. Coco's fashion - sense - related weaponry could combine with Ruby's speed and scythe skills in interesting combat sequences.
Another concept could be a crossover where some of Naruto's friends like Sasuke or Sakura also end up in Moana's world. They all form a team with Moana and her friends to fight against a dark force that is trying to take over the ocean and the land.
One popular trope is the 'What If' scenario. For example, what if Maui didn't leave Moana at some point in their journey? Another is the 'Hidden Relationship' trope, like Moana having a secret connection to another character from her island's past. And the 'Character Development Expansion' is also common, where a writer delves deeper into Maui's backstory, perhaps exploring his early days as a demigod and how he became the Maui we know in the movie. Fanfictions often play with these ideas to create new and interesting stories within the Moana universe.
You can try fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just search for 'Moana' in their search bars and you might find some great Coco - Moana crossovers or Moana - centered fanfictions.
Another plot could be about a magical encounter. Since Coco has elements of the afterlife and magic, baby Miguel could have a brief encounter with a spirit from the Land of the Dead. This spirit could bestow a special gift upon him, like the ability to see music in colors, which is unique to him and shapes his view of music as he grows.
Well, you could write a fan fiction where Moana discovers a hidden underwater civilization. This civilization has its own unique culture and powers. She could learn from them and bring new knowledge back to her own people. Also, a story about Moana teaching others in her village how to sail better and explore farther could be really cool. And there's always the idea of Moana going on a journey to find a long - lost relative who was also an adventurer.
One interesting plot could be Hermione's struggle with identity in a world that has different expectations of a black witch. She might face unique forms of discrimination within Hogwarts and use her intelligence to fight against it. For example, she could form a club to promote equality among different races in the wizarding world.
One interesting RWBY Fox and Coco fanfiction could be about their adventures before joining Beacon. Maybe they were on a mission to stop a small - scale Grimm invasion in a remote village. They had to rely on each other's skills, with Fox's enhanced senses and Coco's weaponry expertise. Another could be a story where they get lost in a mysterious forest during a training exercise and have to find their way out while facing unexpected challenges.
