Ideas for a Moana crossover fanfiction?

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.

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.

Imagine a fanfiction where Moana and the Little Mermaid embark on an adventure to a mysterious island in the middle of the ocean. This island is said to hold the key to a powerful magic that can heal any damage to the ocean. Moana would be excited to explore the island, while Ariel would be a bit more hesitant as she is used to the underwater world. But once they land, they discover that the island is full of strange and wonderful things. They meet creatures that are part - plant, part - animal, and they have to solve puzzles to get closer to the magic. Their different perspectives and skills would make this a thrilling and unique adventure.

It could be about Naruto somehow ending up in Moana's world. Maybe he uses his ninja skills to help Moana on her journey to save her island. For example, Naruto could use his shadow clone jutsu to do multiple tasks at once like helping to repair damaged parts of the island while Moana focuses on finding the heart of Te Fiti.

One idea could be that they go on adventures together to explore new islands. Maui could use his strength and Moana her navigation skills.

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.

In this fanfic, Moana is on a new voyage and gets lost in a mysterious part of the ocean. She ends up near Ariel's territory. Ariel, who has always been interested in humans, approaches Moana. At first, Moana is a bit startled by a mermaid but soon realizes they share a common love for the ocean. They start to exchange knowledge. Ariel shows Moana some of the amazing underwater wonders she has never seen before, and Moana teaches Ariel about the stars that help her navigate. Together, they face a sea monster that is causing trouble in both their areas of the ocean.

One idea could be a story about Moana's journey during her pregnancy. It could focus on how she still tries to maintain her connection with the ocean and her village. Maybe she teaches the children about the importance of nature even while she's expecting.

It could be Orochimaru. Imagine he discovers the power of the ocean in Moana's world and wants to use it for his own dark experiments. He could start corrupting the sea creatures and causing chaos on Moana's island. Naruto, having faced Orochimaru before, would know his weaknesses and team up with Moana to stop him.

A cool plot could be that a dark force from Naruto's world has found a way into Moana's world. Naruto, with his knowledge of fighting evil, and Moana, with her knowledge of the local terrain and the ocean, must work together. Naruto might be a bit clumsy at first with the whole sailing thing, but his combat skills are invaluable. Moana, on the other hand, can communicate with the ocean to get them out of tight spots, and together they defeat the dark force.
