A group of outcasts from different islands might kidnap Moana. They feel that they have been wronged by the 'normal' society that Moana represents. They hope that by kidnapping her, they can get the attention they deserve and force the islands to change their ways. But Moana listens to their grievances and tries to find a way to help them while also finding a way home.
Well, it could be that pirates kidnap Moana. They have heard tales of her island's treasures. Once on their ship, Moana has to face the rough and rowdy pirates. She manages to befriend some of the more sympathetic ones among them and together they plot against the cruel captain. Eventually, she uses her knowledge of the sea to help them all when they get into trouble, and in return, they set her free.
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.
One idea could be that Moana discovers a hidden part of the ocean that has a special connection to her ancestors. The ocean could lead her there, and she might find ancient artifacts or powers that help her protect the island in a new way.
One idea could be a Moana crossover with Frozen. Moana could end up in Arendelle due to a magical storm. She teams up with Elsa and Anna to stop an approaching iceberg that is threatening both her island and Arendelle. Moana's skills in sailing and her connection with the ocean could be combined with Elsa's ice powers to find a solution.
To start writing your own Moana fanfiction, you should start by immersing yourself in the world of Moana. Listen to the soundtrack, look at the beautiful scenery in the movie. Then, think about what part of the story you want to expand on. For example, you could focus on Moana's life before she set sail. You can also take inspiration from Polynesian mythology, as the movie is based on it. Write down your ideas as they come to you, and don't be afraid to let your creativity run wild.
One possible fanfiction could be that Moana's boat gets magically transported to Ariel's underwater world. Moana is amazed by the colorful corals and strange sea creatures. Ariel shows her around and they become friends, sharing stories of their different worlds.
Perhaps the male OC is a mysterious figure who appears to Moana in her dreams before she even sets out on her journey. He seems to know a great deal about the heart of Te Fiti and the approaching darkness. When they finally meet in person, he reveals that he has a connection to an ancient power that can either help or hinder Moana's mission, and she has to figure out how to work with him.
They would become more united as they have a family now. They would have to work together to take care of the baby, so their relationship would be deeper and more responsible.
Moana would probably be very curious about Elsa's ice powers. She might ask Elsa to show her how she creates ice sculptures. Elsa, on the other hand, would be interested in Moana's fearless attitude towards the ocean. They would start by sharing their different cultures. Moana would tell Elsa about the traditions of her island and Elsa would share about the life in Arendelle.
