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 heroism. The boy usually shows great courage and self - sacrifice to save the girl, becoming a hero in the story.
One popular 'Merman Saves Girl' fanfiction could be 'The Merman's Rescued Love'. In this story, the merman discovers a girl drowning during a storm at sea. He uses his powerful tail to swim to her quickly and brings her to the safety of a hidden cove. There, they begin to form a special bond as the girl recovers.
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.
They might end up enemies. For instance, if the merman has a different view on humans after being saved. Maybe he thought humans were all bad before, but now he's conflicted because this girl saved him. Or perhaps the girl accidentally reveals the merman's existence to others, which angers the merman and his kind.
One common theme is the mystery surrounding the merman. In many fanfictions, the merman is an enigma at first, and the reader is drawn to figure out his secrets. Also, there's the theme of acceptance. The merman has to accept the human world and the reader has to accept the merman's non - human nature. Connection to nature is another theme. The relationship between the merman and the reader often reflects a deeper connection to the ocean and nature in general.
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.
Well, one possibility is that the merman becomes indebted to the girl. He might then use his merman powers, like being able to communicate with sea creatures, to help the girl in some way. For example, if the girl's village is facing a shortage of fish, the merman could guide the fish back to their shores.
