In some sakura mermaid fanfiction, the mermaid could be on a quest to find a lost pearl that has the power to bring eternal spring to the ocean. Along the way, she meets different sea - faring characters and overcomes various challenges.
One great Merlin mermaid fanfiction is 'The Mermaid's Gift'. In this story, Merlin discovers a mermaid in a hidden cove. The mermaid has special powers that she uses to help Merlin protect Camelot from a new threat. It's a really interesting take on the Merlin universe combined with mermaid lore.
One great mermaid TF fanfiction is 'The Mermaid's Transformation'. It has an interesting plot where the main character gradually turns into a mermaid in a very magical way. The description of the underwater world and the mermaid's life is vivid.
One great Snape mermaid fanfiction is 'The Mermaid's Secret'. In this story, Snape discovers a mermaid in the Black Lake at Hogwarts. The mermaid has a special connection to the magical essence of the lake. Another one could be 'Snape and the Mermaid's Quest' where Snape is tasked with helping the mermaid solve a mystery that endangers both the underwater world and Hogwarts. And 'Mermaid's Allure for Snape' shows how the mermaid's presence affects Snape's usually stoic nature.
One good mermaid story is 'The Little Mermaid' by Hans Christian Andersen. It tells of a young mermaid who falls in love with a human prince and makes a great sacrifice to be with him. Another is 'Aquamarine' which is about two girls who find a mermaid in their swimming pool. And 'Mermaids: The Body Found' is also interesting as it presents a more scientific - yet fictional - take on the existence of mermaids.
Well, perhaps in the fanfiction, Sakura is a mermaid princess and Sasuke is a warrior from a nearby underwater kingdom. They meet during a battle between their kingdoms. Instead of fighting each other, they are intrigued by one another. Sakura's beauty and kindness make Sasuke question his loyalty to his own kingdom, and they start a secret relationship while trying to end the war between their people.
In her mermaid form, Sakura could have a very large and powerful tail. The scales on her tail could be a bright pink with a blue - green sheen to them. Her eyes might be a different color, perhaps a deep blue to match the ocean. She could have gills on the sides of her neck that are very delicate and almost look like flower petals when they open and close. And her hands could be webbed slightly to help her swim faster in the water.
One idea could be that Sakura discovers she has mermaid ancestry. Maybe she starts having strange dreams about the ocean and then one day, while at the beach, she accidentally touches a special seashell that triggers her transformation into a mermaid. She then has to learn to navigate this new part of her life while keeping it a secret from her friends in the ninja village.
In a mermaid setting, their relationship might start slowly. Sasuke could be initially hesitant as he is new to the mermaid world. Sakura, being more familiar, would help him. As time passes, they would go on adventures together, exploring the underwater caves and hidden treasures. This shared exploration would bring them closer and their relationship would gradually develop into a deep love.
One great sakura and syaoran fanfiction could be 'A New Adventure'. It might show them exploring a new magical realm together, facing challenges and growing closer. Another could be 'The Reunion' which focuses on their reunion after a long time apart and how they rekindle their relationship. And 'The Hidden Power' where they discover a new power within sakura and work together to control and use it for good.
