Another idea is that Harry has to face Voldemort in a new way. Since he is a Dragonborn, he can call upon dragons to aid him in the battle. The dragons could be used to attack Death Eaters or to create a distraction while Harry uses his combined wizard and Dragonborn skills to finally defeat Voldemort. Maybe the dragons are attracted to the powerful magic that Voldemort wields and see it as a threat to their territory.
A plot could also involve Harry traveling to different realms. As a Dragonborn, he has the ability to cross between the wizarding world and the world of Skyrim. He brings back knowledge and magic from Skyrim to Hogwarts, introducing new forms of magic that are not known in the wizarding world. This causes a stir among the teachers and students, and some are excited about the new possibilities, while others are fearful of the unknown magic.
Maybe the Dragonborn and Harry Potter team up. The Dragonborn teaches Harry about ancient magic that is similar to his Thu'um, and Harry teaches the Dragonborn about wizardry like Apparition. They could go on a quest to find a powerful magical artifact that is being sought by Voldemort and a powerful dragon in the fanfic world.
A third plot idea is that fem Harry Potter is actually a long - lost relative of Loki in some convoluted way. This discovery leads to a series of events where they have to work together to uncover the truth about their shared heritage. Along the way, they face opposition from both the wizarding community who fear her newfound connection and some Asgardians who don't trust an outsider.
One plot idea could be Harry using his time - controlling power to go back and prevent Voldemort from ever rising to power in the first place. He could change key events in the past that led to Voldemort's ascension, like ensuring that Tom Riddle never opened the Chamber of Secrets or that he didn't get the job at Hogwarts. Another idea is that Harry travels forward in time to see the future of the wizarding world and then comes back to make changes in the present to avoid a disastrous future, such as a war between different magical races. A third plot could involve Harry getting stuck in a time loop, and he has to figure out how to break it while also using his knowledge of the repeated events to his advantage, like saving his friends from a danger that he now knows will occur multiple times.
One interesting 'godlike dragonborn fanfiction' could be about a dragonborn with god - like powers who uses them to bring peace to a war - torn land. They might have the ability to control all elements and communicate with every creature.
A really cool plot idea could be that the OC Dragonborn has a split personality. One side is a fearless warrior, ready to take on any dragon or foe. The other side is a pacifist who tries to find non - violent solutions to problems. This internal struggle could be a major part of the fanfiction, as they deal with the challenges of being the Dragonborn in Skyrim and having these two conflicting natures.
One idea could be that the Dragonborn is forced to make a pact with a Daedra to gain power to defeat a great evil, but then has to deal with the consequences of that pact. For example, the Daedra might demand certain sacrifices or tasks in return.
Perhaps a plot where the dragonborn has to adapt to the modern world of Highschool DxD while also hiding their true nature. They might struggle with the different social norms and also have to keep their dragon powers a secret from most people, except for maybe Issei and his friends who could help them fit in.
Well, you could do a crossover where Harry has the powers of a godlike being from Japanese mythology, like Amaterasu. He could have the power of the sun, using it to vanquish evil. Maybe he could also cross with a powerful African deity and incorporate their unique magic into his existing skills, creating a whole new set of spells and abilities.
There are fanfictions where the Dragonborn's Thu'um (the power of the Voice in Skyrim) has an impact on the magic in the Harry Potter world. Maybe they use shouts to break powerful spells or to enhance their own magical abilities. In some fanfictions, the Dragonborn becomes a sort of protector of Hogwarts, using their unique skills to fend off dark wizards and creatures.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
