One interesting plotline could be Harry Potter using dragons to protect Hogwarts from a new dark threat. He might train them to patrol the grounds and skies around the school. Another could be that he discovers a new breed of dragon with unique magical abilities and has to work with it to solve a mystery related to an ancient wizarding prophecy.
In some fanfictions, Harry Potter might work with dragons in a dragon - racing context. He could be training dragons for a big international dragon - racing event. This would involve him getting to know the different personalities and abilities of each dragon he works with. Along the way, he might encounter rivals who try to sabotage his dragons or steal his training techniques. And, of course, there could be a sub - plot where the dragons themselves form bonds with Harry and help him in other aspects of his wizarding life, like when he's facing challenges at Hogwarts or dealing with the Ministry of Magic.
Maybe Harry is given a dragon as a gift or as part of a special task. He then has to raise the dragon while also dealing with the challenges of his regular school life at Hogwarts. He might have to use his knowledge of magic to keep the dragon healthy and well - behaved. The dragon could also become his protector or help him in some dangerous situations. Another plotline could be that the dragon is a key to unlocking some ancient wizarding secret, and Harry's task of raising it is part of a bigger prophecy or mission.
One plotline could be that Harry discovers a hidden dragon sanctuary within Hogwarts grounds that has been long forgotten. The dragons there are in danger due to some dark magic that is slowly poisoning them. Harry, with his natural ability to communicate with magical creatures, befriends the dragons and tries to find a way to save them. He has to face many challenges like dealing with the Hogwarts authorities who don't want him to interfere and the source of the dark magic.
In some fanfictions, Dobby uses his unique magic skills to create elaborate pranks against Harry's enemies at Hogwarts, which adds a lot of humor to the story.
In some fanfictions, Muggle dragons might be hidden from the wizarding world. They could live in remote, Muggle - only areas, like deep in uncharted jungles or deserts. Maybe they have different abilities compared to wizard - known dragons, such as being able to blend in with their surroundings better to avoid detection by Muggles.
A common plotline is the culture shock. For example, a Beauxbatons student might be shocked by the more laid - back atmosphere at Hogwarts compared to the strict elegance of Beauxbatons. Another plotline could be a Beauxbatons student falling in love with a Hogwarts student and having to navigate the differences in their magical upbringing. For instance, in some fanfics, the student has to deal with the disapproval of their family or school because of this relationship.
One interesting plotline could be exploring their relationship in their early Hogwarts days more in - depth. Maybe showing how Severus first fell in love with Lily and the little moments they shared in the library or on the grounds. Another could be a what - if scenario where Lily didn't end up with James and Severus had a chance to rekindle their friendship and perhaps more. A third could be a story from Severus' perspective after Lily's death, how his memories of her still haunted and drove him in his actions within the wizarding world.
Maybe in this fanfiction, they are raised together and form a pact to end the long - standing feud between Gryffindor and Slytherin houses in Hogwarts. They work towards bringing unity among the students through various magical projects and initiatives.
One possible plotline could be Harry finding a way to break free from the cycle of abuse by relying on his friendships. For example, Hermione and Ron could discover what's going on and use their magic skills and wits to protect Harry. They might create a safe haven for him within Hogwarts, using protective spells and charms.
One possible plotline could be Harry struggling to hide his Tourettes symptoms at Hogwarts in the beginning. He might be afraid of being judged by his classmates. For example, during a Potions class, his tics could cause him to accidentally add the wrong ingredient, leading to a minor magical mishap. Another plotline could involve Harry using his magical abilities to find a way to manage his Tourettes better. He could go on a quest to find a rare magical herb or spell that helps him control his tics. Also, his friends like Hermione and Ron could play a big role in supporting him, learning about Tourettes, and standing up for him when others are unkind.
One interesting plotline could be Harry discovers a hidden alchemy book in the Room of Requirement. He then starts to experiment with alchemy to create powerful potions that have unique effects not found in normal magic.
