Well, a great plot idea could be that the male with wings is a messenger from the gods. He has to deliver important prophecies to the different holds in Skyrim. However, many of the Jarls don't believe him at first because of his strange appearance. His wings also make him a target for bandits who want to capture him and sell him to some sort of dark magic user. As he travels, he meets a group of adventurers who help him on his mission.
Maybe the male with wings is part of an experiment gone wrong by a mad wizard. He escapes the wizard's lair and now tries to blend into Skyrim society. But his wings keep getting in the way. He could start off as a loner, but as he gets involved in local events, like helping a village deal with a plague of giant spiders, he gradually earns the respect and friendship of the people. His wings end up being an advantage as he can scout from above and warn of approaching threats.
One idea could be that the male vampire dragonborn struggles with his dual nature. He has the power of the dragonborn but also the thirst for blood as a vampire. For example, he might face a moral dilemma when using his dragon shouts to save a village that is afraid of his vampiric side. Another plot could involve him seeking a cure for his vampirism while still trying to fulfill his destiny as the dragonborn. He could travel to ancient ruins in search of a lost spell or artifact that might reverse his condition.
Maybe Harry gets involved in the civil war in Skyrim. He could use his Hogwarts-taught dueling skills to fight in battles, and his knowledge of magic could be used to solve some of the political intrigues. He might also try to find a way to bring peace to Skyrim using his unique perspective on magic.
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 from Skyrim somehow gets transported to the post - apocalyptic world of Fallout 4. Maybe they have to deal with the new threats like the raiders and mutants using their dragon - slaying skills. Another plot could involve the Sole Survivor from Fallout 4 finding a way into Skyrim and getting caught up in the civil war there, having to choose a side while also trying to find a way back home. Or perhaps a magical artifact from Skyrim ends up in Fallout 4 and causes all kinds of chaos as different factions fight over it.
A cool plot could be that a powerful artifact in Skyrim is causing chaos and the Fairy Tail members are summoned to find and secure it. Along the way, they meet up with the Dragonborn. Some members might befriend the Dragonborn and help in their battles, while others might be a bit more skeptical and think the Dragonborn is a threat to their own power within the group.
One idea could be that the Master Chief is somehow transported to Skyrim. He might use his advanced combat skills and technology to deal with the dragons. For example, his energy shields could protect him from dragon fire. Another plot could involve the races in Skyrim getting access to Halo's weaponry and having to figure out how to use it. Maybe the Dwemer could reverse - engineer Covenant weapons.
A time - traveling dragonborn could be sent back to the era when dragons first arrived in Skyrim. They would have to use their dragonborn powers in a different context, maybe even having to learn new ways to control their abilities. They could also try to change the relationship between dragons and humans from the very beginning.
One idea could be a character from Fallout finding themselves in Skyrim. Maybe they bring their advanced weaponry, like a laser pistol, into Skyrim's medieval - like world. This would cause quite a stir among the locals, who have never seen such technology. The character could then get involved in Skyrim's political intrigue, using their unique skills to help or hinder different factions. Another plot could involve a Skyrim mage traveling to the Fallout wasteland. They would be amazed by the strange, post - apocalyptic magic (technology) there and try to learn about it, while also using their own magic to survive against the mutated creatures.
One idea could be a Hobbit finding their way into Skyrim. Maybe they get mistaken for a child at first due to their small stature. They could bring their Hobbit - like skills of stealth and a love for food. For example, they might start a small cooking business in one of Skyrim's towns, using unique Hobbit recipes and ingredients they manage to find in Skyrim. This could attract all kinds of characters, from the local Nords to the wandering adventurers.
One idea could be that Percy Jackson finds himself magically transported to Skyrim. He could use his water - bending abilities in the frozen landscapes, perhaps to help deal with frost trolls by using water to freeze their legs or something. Another plot could involve Annabeth Chase coming to Skyrim and using her strategic mind to navigate the political intrigues of the different holds. And maybe a demigod from PJO teams up with a Dragonborn in Skyrim to fight a common enemy like an ancient evil that threatens both their worlds.
