One great merman Harry Potter fanfiction is 'The Merman's Magic'. It has an interesting plot where Harry discovers he has a connection to the merman world. The author does a great job of blending the magical elements of the Potterverse with the unique lore of mermaids and mermen.
One possible plotline could be Harry trying to hide his merman identity while at Hogwarts. He might face challenges in the magical underwater areas of the school, like the lake. Another could be that he discovers his merman heritage and has to go on a journey to learn more about it and his new powers.
The combination of two very different concepts. Harry Potter is all about magic on land, in a school, with wizards and witches. Mermen bring in a whole new element of an underwater world full of mystery and different kinds of magic. It's like opening a new door in the already vast Potterverse.
Well, it could start with Harry being cursed by a dark spell during one of his adventures near the Black Lake. Suddenly, he starts to feel strange sensations and discovers his legs are fusing together and turning into a merman's tail. He has to adapt to this new form. Maybe he discovers he can communicate with the merfolk in a different way now and they have some secrets about the wizarding world that only he can learn in this form.
It could be a rogue wizard who wants to use Harry's new merman form for his own evil purposes. Maybe he wants to study Harry's transformation to find a way to create an army of half - human, half - merman creatures to take over the wizarding world and the underwater realm.
Yes, there are some fanfictions with the concept of Harry Potter as a merman. You can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just type in relevant keywords and you might find some interesting ones.
Friendship and acceptance is also a big theme. The merman character is usually an outsider in the Hogwarts world, and the story often focuses on how the other characters come to accept and befriend him. This is similar to how Harry Potter was an outsider at first in the wizarding world but found his place. In some fanfics, the merman might face discrimination at first because of his different appearance and abilities, but then through his actions and the kindness of others, he becomes part of the community.
Well, one unique element is the combination of two different mythologies. You have the well - known wizarding world of Harry Potter and the less explored merman lore. For example, in some fanfics, mermen might have their own type of magic that is different from what wizards use.
One idea could be that Harry discovers a hidden centaur community in the Forbidden Forest. He's initially scared but soon realizes they have a deep connection to magic that Hogwarts has not taught. He starts learning from them, about their archery skills and how they communicate with nature.
If Harry Potter becomes a Sith in fanfiction, it would be a wild departure from his original character. He'd likely trade his Gryffindor values for the dark and power - hungry ways of the Sith. His magic could take on a more menacing form, and his relationships would be severely strained. For example, his friendship with Ron and Hermione might turn into enmity as he delved deeper into the dark side.
