One possible plot could be Harry's discovery of his unique heritage. Maybe he starts having strange time - related powers, like being able to briefly stop time to escape danger or to look into the past to find clues about Voldemort's weaknesses. Another could be his interaction with other time - related magical beings. For example, he might meet an ancient time - keeper who guides him in understanding his role as the son of the time god.
There could also be a plot where Harry has to use his time - god powers to rewrite certain events in the wizarding world. For instance, he might go back in time to prevent some of the tragedies that happened during the First Wizarding War. However, this could have unforeseen consequences, like creating alternate timelines or changing the nature of some characters. He would then have to find a way to fix these new problems while still fulfilling his destiny as the son of the time god.
Well, in some older Harry Potter time travel fanfiction, the plot might involve Harry traveling back to his own past to fix his mistakes. He might have regrets about how he treated certain people or how he made certain decisions. So, he goes back to make amends. This can lead to some really heartwarming and also tense moments as he tries to change things without causing more harm. For instance, he might go back to when he first met Hermione and be nicer to her from the start. This can then change their relationship in unexpected ways throughout the story.
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.
A plot that I find very intriguing is when a character travels back in time to prevent the death of a loved one. For example, in some fanfics, Harry travels back to save Sirius. This creates a lot of tension as he has to deal with the time - turner rules and the possible consequences of changing the past.
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.
There are also fanfictions that look at Helena Ravenclaw from the perspective of her motherly love for Hogwarts. She's like a protective spirit in these stories, and the plot might involve her guiding certain characters, like Harry or Hermione, through difficult times at Hogwarts. It's a heartwarming and different take on her character that shows her connection to the school in a more emotional way.
Well, in some fanfics, like 'The Darker Side of Redemption', Lucius is given a chance at redemption after the fall of Voldemort. Harry plays a key role in this process, either by being a reluctant helper or an unexpected friend. The plot often involves exploring the darker parts of the wizarding world that were not fully shown in the original books.
One interesting plot could be Harry using his magical skills in veterinary work. For example, he might use spells to heal injured animals quickly. Maybe he'd have to deal with magical creatures that are acting strange and he has to figure out if it's a magical illness or something else.
