What would be the plot of a 'Harry Potter turned into a merman' fanfiction?

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.

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.

In a fanfiction where Harry Potter is turned into a wraith, his magic would likely change too. He might be able to use his wraith form to access places that were previously inaccessible. Maybe he could enter the Forbidden Forest without being detected by the creatures there. But on the downside, he'd be in a constant state of being not quite alive and not quite dead. This could mess with his mind, and he'd have to struggle to hold on to his identity while dealing with his new form.

Well, he'd probably have to deal with a whole new set of powers and weaknesses. He might be able to move faster and have enhanced strength like regular vampires. But he'd also have to face the thirst for blood, which would be a huge struggle considering his moral code. And his relationships with his friends would change. They might be scared of him at first, or he might have to keep his new condition a secret from them to protect them.

In such a fanfiction, Harry might gain the physical abilities of a basilisk. He could have its incredible strength and speed. Maybe he would also inherit the basilisk's venomous nature, which could be both a weapon and a danger to those around him. Also, his appearance would change drastically, with the snake - like body and menacing eyes.

If Harry Potter became a vampire in fanfiction, his relationships would change a great deal. His friends might be scared of him at first. Hermione would probably be researching like crazy to find a way to reverse it or at least help him manage. Ron might be more hesitant to be around him, but still loyal in his own way.

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.

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.

In the 'Harry Potter gets turned into a cat' fanfiction, there could be a lot of comical situations. Imagine Harry trying to attend classes as a cat. He might jump on desks, knock over ink bottles, and cause chaos in the classroom. His professors would be very confused about this strange cat's behavior. And when it comes to fighting Voldemort, it would be a very different scenario. He might use his cat - like agility to dodge spells, but also have to find a way to cast his own magic in this new form.

Maybe Harry is the only merman in a world where mermaids are common. He faces discrimination at first but then uses his unique abilities to save the underwater kingdom from a great danger. For example, he might have a special power to purify poisoned waters that the mermaids don't have.
