What are the common themes in merman x reader fanfiction?

Love and acceptance are common themes. Since mermen are from a different species, there's often a plot about the reader accepting the merman's differences and falling in love despite them.

Adventure is also a big theme. Since Percy is a merman, there are often underwater adventures involved. They could be exploring sunken ships, finding lost treasures, or facing off against sea monsters. Jason, with his own set of skills, joins in these adventures, and together they make a great team. It's all about the thrill of the unknown and the challenges they overcome as a duo.

One common theme is the exploration of their relationship in a new, underwater world. Since they are mermen, it adds a different dynamic to their already complex bond.

One common theme is identity. Since Naruto is usually a human in the original series, when he becomes a merman in fanfiction, he has to figure out who he is in this new form. Another theme is acceptance, as he may face prejudice from both humans and mermen.

One common theme is self - discovery. Harry often has to figure out what it means to be a merman and how to use his new abilities. Another theme is acceptance, both from himself and from others. Since he's different now, he has to face those who might not accept him at first.

Love is a very common theme. Often, it's about a merman OC falling in love with a human or another merman. Another common theme is adventure. Merman OCs usually go on some sort of journey, whether it's exploring a new part of the ocean or trying to reach the surface world.

A sense of belonging is another big theme. The reader, who may feel like an outsider in the real world, finds a place where they belong among the mutants. There are also themes related to fighting for justice, just like the X - Men do in the original stories.

A sense of wonder and magic is also a common theme. The very existence of mermen in these stories is a magical element. When the merman saves the girl, it's not just a physical rescue but also an introduction to a world full of wonder. The merman might have special powers like controlling the sea or communicating with sea creatures, and this all adds to the sense of magic in the fanfiction.

A major theme is acceptance. The merman has to accept the human girl's way of life on land, and the girl has to accept the merman's aquatic existence. There's also the theme of sacrifice. Sometimes, either the merman or the human girl has to sacrifice something important for their relationship. For instance, the merman might have to give up his life in the sea to be with the girl on land, or the girl might have to leave her family and normal life to be with the merman in the ocean.

One common theme is adventure. Since Chekov is part of the Star Trek universe, many fanfictions involve the reader going on adventures with him through space, exploring new planets and facing various challenges.
