A common plot also involves a dragon being the key to a mystery. For example, a dragon might be guarding a secret passage between the wizarding world of Harry Potter and the Middle - earth of The Hobbit. Characters from both universes would then have to work together to either befriend the dragon or find a way around it to uncover the mystery. This often leads to interesting character interactions and the exploration of different magical cultures.
One popular plot is the discovery of a dragon egg. In fanfiction, it could be a situation where a character from either universe stumbles upon a dragon egg. If it's a Hogwarts student, they might try to hide it from the teachers and figure out how to hatch it, while also dealing with the potential danger it poses. If it's a character from The Hobbit, they might see it as a great treasure or a sign of something more significant.
Many fanfictions explore the idea of a dragon - rider. A character, perhaps a brave Hogwarts student or a fearless Hobbit - like character, forms a bond with a dragon and rides it. This can be used to show the character's growth in power and confidence. They could then use the dragon to travel between the two fictional worlds, facing various challenges along the way and becoming a sort of legend in both universes.
There are also fanfics with a plot where Harry discovers a lost dragon species that has special powers related to time or space. This discovery leads him on a journey to understand these powers and how they can be used to rewrite the history of the wizarding world, or perhaps even prevent some of the tragedies that have occurred in the past. It's a very creative and engaging plot idea that takes the Harry Potter universe in a new direction.
Well, a common plot involves the characters swapping places. Luffy ending up in Hogwarts and having to deal with magic lessons while Harry finds himself on the Thousand Sunny. Also, there are plots where they team up to solve a common threat that endangers both their worlds, like a new dark magic that spreads to the One Piece world.
In some fanfiction, dragons in the Harry Potter and Hobbit universes might be combined in terms of their magical abilities. For example, a dragon in a crossover fanfic could have the intelligence of a Hobbit - dragon like Smaug but also be able to use magic like the dragons in Harry Potter. They could be used as powerful plot devices, perhaps guarding a powerful magical artifact that both wizards from Harry Potter and characters from The Hobbit are after.
There are also plots where different dimensions are on the verge of colliding. This creates a sense of danger and urgency as the characters have to prevent the collision which could have catastrophic consequences for both their world and the other dimensions. In some fanfictions, a villain might be trying to use the power of different dimensions to take over the wizarding world.
One popular plot is the redemption of werewolves. In these fanfictions, Harry Potter or other characters use their control methods to help werewolves integrate into wizarding society.

One popular plot is Gohan's power - up journey. Fans love to see him reach new levels of strength. This could be through a new form or by unlocking hidden potential. For instance, he might discover a way to combine his human and Saiyan genetics in a unique way to gain a power boost.
A common plot is that Malfoy spreads false rumors about Harry in the wizarding world. This causes problems for Harry, like making some students avoid him or look at him with suspicion. When Harry finds out that Malfoy is the source of these rumors, he gets angry and beats him up. There are also fanfictions where Malfoy tries to get Harry expelled from Hogwarts by framing him for something he didn't do. Harry, being the brave character he is, doesn't take this lying down and gives Malfoy a good thrashing.
Some fanfictions explore the concept of Sebastian being a sort of protector or mentor to Harry. This could be a very different take on Harry's growth compared to what we see in the original books. With Sebastian's knowledge and skills, he could help Harry in ways that Dumbledore or other characters couldn't. It could also lead to some really interesting character dynamics as Harry tries to balance his Gryffindor values with Sebastian's more morally ambiguous ways.
One popular plot is where a female Harry Potter becomes an apprentice of Newt Scamander. They go on adventures together, exploring the magical creatures' world.

There's also the plot where the two are forced to fight because of a spell or a curse that makes them see each other as enemies.
