In a Naruto and the Little Mermaid crossover, Naruto could be transported to the underwater kingdom. There, he meets Ariel who is fascinated by his strange powers. Together, they could team up to find a way to stop an evil force that is threatening both the surface world (where Naruto is from) and the underwater world. Naruto's ability to make clones could be used in interesting ways underwater, like creating distractions for the bad guys.
Maybe a new character, a powerful sea witch who has been influenced by the power - hungry ways of some of Naruto's villains. She wants to rule both the underwater world and the land world above. She would use her magic to create chaos and try to stop Naruto and Ariel from uniting their forces.
One possible plot could be that Sora and his friends land in the underwater world of The Little Mermaid. Ariel could be in trouble, perhaps captured by the Heartless. Sora, with his Keyblade, would fight to free her. Donald and Goofy could help by using their magic and strength respectively. They would then have to find a way to restore the underwater kingdom's heart which has been affected by the Heartless presence.
Sora would likely be very protective of Ariel. He would see her as someone in need of help, just like he does with many characters in different worlds. Ariel, on the other hand, would be fascinated by Sora's world and his Keyblade. She might ask him a lot of questions. Donald could get frustrated with Ariel's overly curious nature at times, while Goofy would just be friendly and go along with whatever is happening.
In a fanfiction, Serena as a mermaid might be part of a mermaid kingdom that has a long - standing feud with a group of sea - dwelling Pokemon. Serena, being kind - hearted, tries to bridge the gap between the two sides. She uses her charm and the skills she has learned in the Pokemon world to negotiate peace, all while looking stunning with her mermaid tail and long flowing hair.
In this fanfiction, Triton, the powerful sea king, discovers a hidden cove in his vast ocean realm. This cove has a unique magic that shows him visions of the future of his daughters. He sees Ariel's continued fascination with the human world and realizes that his strict rules may be pushing her away. Triton decides to have a heart - to - heart with Ariel, opening up about his own past experiences with humans. He tells her of a time when he was young and saved a human sailor from a storm, and how that encounter both intrigued and scared him. This new understanding between them begins to heal the rift in their relationship.
It's the new and exciting characters that make this fanfiction appealing. Octavious, for instance, might bring a fresh perspective to the familiar Little Mermaid setting. He could be a rebel among the mermaids, challenging the old traditions and ways of life underwater.
Maybe it could be about the little mermaid's new adventure in an undiscovered underwater kingdom. She might meet new friends or face new enemies there.
Adventure is a big theme too. Many 'little mermaid fanfiction' stories take the characters on exciting journeys, whether it's exploring uncharted parts of the ocean, or traveling to far - off lands on the surface. These adventures often test the characters' courage and loyalty.
