One common theme is the mermaid's struggle between two worlds. For example, their life in the ocean and their newfound connection to the supernatural world on land. This creates a lot of internal conflict for the mermaid characters.
A frequent theme is the exploration of new powers. As a mermaid, Harry would have different abilities like swimming super - fast or communicating with sea creatures. This often leads to adventures where he uses these powers to solve problems or discover new things. Also, there's the theme of the relationship between the land and the sea. How Harry bridges the gap between the two worlds he now belongs to is an important part of many such fanfictions. He may have to bring the two cultures together to overcome a common enemy or achieve a common goal.
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.
The theme of discovery is also common. The mermaid herself might be discovering new powers or abilities related to her pregnancy. And there could be a discovery by the human world or other sea creatures about the pregnant mermaid. This could lead to all sorts of adventures and interactions, like the mermaid trying to hide her pregnancy or having to face the consequences of it being revealed.
One common theme is transformation. Characters often transform into mermaids or gain mermaid - like abilities, which brings about a whole new set of adventures. Another theme is the discovery of new powers, like the miraculous powers in a mermaid - centered world.
Love and relationships are also prevalent. For example, in 'Bella and the Mermaid Prince', there's a romantic relationship between Bella and a mermaid prince, which adds a lot of drama and emotional depth to the story. And sometimes there are also complex friendships formed within the mermaid community in different fanfictions.
Love is a very common theme. Usually, a mermaid and a human fall in love despite their differences. Another theme is the struggle between two different worlds. The mermaid belongs to the underwater world and the human to the land world, and they have to find a way to be together.
In 'supernatural fanfiction', a frequent theme is the alternate universes. Writers like to imagine different versions of the 'Supernatural' world, where things happened differently. Romance is also a big theme, whether it's between the main characters or new characters introduced in the fanfic. Also, the origin stories of the supernatural beings are often explored, giving more background and depth to the existing lore.
Friendship is a very common theme. Just like in the original My Little Pony and The Little Mermaid stories, the fanfictions often focus on characters from both universes forming strong bonds of friendship. For example, Ariel might make friends with Fluttershy, and they help each other overcome their fears.
Many 'Pokemon Dawn Mermaid' fanfictions have the theme of protecting the underwater world. Dawn, as someone with a connection to both the Pokemon world and the underwater mermaid world, has to fight against threats to the underwater ecosystem. This could be from villains who want to pollute the water or capture rare Pokemon. It's a way to combine the environmental aspect of Pokemon with the fantasy of the mermaid world.
One common theme is the exploration of Bella's identity. Since she's a mermaid in these fanfictions, it often looks at how she reconciles her new mermaid self with her human side. Another theme is the relationship changes. Her being a mermaid can greatly impact her relationships with Edward, Jacob and others.
