Another plot might be about a merman who has a connection to the wizarding world's secrets. He could be an outcast in the merman society because of his interest in magic. He meets Harry Potter and together they try to uncover a mystery that links the underwater world of mermen and the wizarding world above. For example, they might discover an ancient magic that was lost between the two worlds.
One interesting plot could be a merman helping Harry Potter in his underwater challenges. Maybe in a Triwizard Tournament task that involves the Black Lake, a merman uses his unique abilities to guide Harry through dangerous underwater mazes or fend off dangerous creatures.
Well, in some fanfictions, the female werewolf might be on a quest to find a cure for her condition. This could lead her to encounter various magical creatures and ancient spells. Or perhaps she is part of a secret werewolf community within the wizarding world that has its own rules and politics. Her story could then be about trying to change the way werewolves are treated in that community and in the wider wizarding society.
One interesting plot could be Myrtle helping Harry in a way that only she can, like using her knowledge of the castle's secrets. Since she haunts the girls' bathroom, she might know about some hidden passages or magical items there that could assist Harry in his adventures.
Well, in some of these fanfictions, a plot could revolve around a forbidden relationship between a wizard and a magical creature. For example, a mermaid and a wizard falling in love. This would bring about all sorts of complications, like how they would communicate and interact in different environments. Or perhaps a story where a phoenix chooses a very unlikely wizard as its companion, and they go on adventures that are not part of the traditional Hogwarts curriculum. It's these unique twists on the relationship between humans and magical creatures that can be really captivating.
In Harry Potter fanfiction about pureblood politics, it often delves into the power struggles within the wizarding world. Pureblood families like the Malfoys believe in their own superiority. Fanfictions may explore how they try to maintain their status, for example, by influencing Hogwarts' policies or wizarding government. It can also show the conflicts between purebloods and half - bloods or Muggle - borns in a more detailed and creative way than in the original books.
The plot where Murtagh teaches Harry some of his unique magic techniques is really cool. It shows how different magical systems can interact. For example, in a fanfic I read, Murtagh showed Harry how to use a spell that was common in his world but unheard of in Hogwarts.
One interesting storyline could be a hybrid character struggling to find their place in the wizarding world. They might be shunned by both vampires and werewolves, yet possess unique powers that could be useful in the fight against dark magic. For example, their vampire side could give them enhanced speed and strength, while their werewolf side might offer a connection to nature that helps in certain spells or potions. Another could be a love triangle between a vampire - werewolf hybrid, a pure - blood wizard, and a Muggle - born witch, exploring themes of prejudice and acceptance in the magical community.
In 'The Mysterious Bond between Harry and Grindelwald', the plot focuses on a strange, unspoken bond that seems to exist between the two. This bond affects their decisions and actions throughout the story. It's a unique take on their relationship and makes for a very engaging read.
One of the most interesting plots could be Snape having to protect Harry in a very unexpected way. For example, in a fanfic where dark magic has been unleashed in a different form and it targets Harry specifically. Snape, despite his initial reluctance, realizes that Harry is the key to stopping it and has to put aside their differences. Another plot could involve Snape and Harry being transported to an alternate magical realm where they have to rely on each other to survive. They slowly start to understand each other's past traumas and develop a grudging respect. A third plot might be that Snape discovers a long - lost prophecy about Harry that changes his perception of him completely and he becomes his secret mentor in a much more involved way than in the original books.
In some fanfics, the plot might involve Harry using his snake form to spy on the Death Eaters. For example, he could slither into their secret meetings undetected. Another interesting plot could be that his snake form is somehow connected to Salazar Slytherin. Maybe he discovers that his ability to turn into a snake is part of an ancient bloodline magic.
A common plot in 'Harry Potter Dolores Umbridge Fanfiction' is her getting a taste of her own medicine. For example, in some stories, she is put through the same strict and cruel rules she imposes on others. It's a satisfying plot for those who dislike her character in the original books.
