A really interesting plot could be that Naruto is mistaken for a powerful wizard. He gets involved in the battle against Sauron. His Rasengan could be a powerful weapon against the orcs and other dark creatures. Also, his friendship with the characters in Middle - earth would grow as they see his loyalty and determination, much like how his friends in the Naruto world value him.
Well, in 'lord of the rings crossover fanfic', the idea of mixing different species from other fictional works can be really engaging. For example, a crossover with the world of 'Game of Thrones'. The political intrigue of the Seven Kingdoms combined with the epic quest of the One Ring. Characters like Tyrion Lannister could meet Frodo and have some really interesting exchanges about power and survival. Or a crossover with the 'Star Wars' universe. The Force could interact with the magic in Middle - earth in a very unique way, and Jedi could potentially have their own take on the One Ring's power.
One possible plot could be Sasuke finding himself in Middle - earth. He might be mistaken for an elf at first due to his appearance. He could then get involved in the fight against Sauron. Maybe he uses his Sharingan to detect the presence of orcs or other dark forces. His ninja skills would be quite useful in battles, like his speed and ability to move stealthily.
Definitely Legolas. His archery skills and elven grace make him a standout character in crossovers. He could easily be part of a team in a superhero - like crossover, using his skills to fight alongside other powerful characters. Another popular one is Gollum. His complex personality and his obsession with the One Ring can add a lot of depth to crossovers. In a crossover with a psychological thriller - type of world, Gollum's internal struggle could be explored even further. And Sauron, as the big bad, can be a great antagonist in crossovers with other powerful villains from different fictional universes.
Well, often there's the element of the vampires being outsiders in Middle - earth. They usually have their own powers and motives that are different from the normal LOTR characters. For example, they might be interested in the power of the One Ring for their own reasons, like using it to enhance their vampiric abilities or gain more control over other beings.
In this crossover fanfiction, Dracula might be a lord in Middle - earth. He rules over a land that is feared by all, but he is intrigued by the power of the One Ring. He sends his minions to find it, but they cross paths with Frodo and his companions. This leads to a series of battles and negotiations. Dracula could be tempted by the power of the Ring, but also realizes that it could bring about his own downfall if he were to claim it.
In fanfiction, Hermione could find herself in a situation where she has to deal with the One Ring. Given her strong will, she might be able to resist its power for a longer time than most. However, she would also be aware of the danger it poses and try to find a way to destroy it, perhaps using a combination of her magic and the knowledge of the lore in Middle - earth.
I think Naruto and Aragorn would interact well. Aragorn is a natural leader, and Naruto has leadership qualities too. They could share their experiences in leading their respective groups. Also, Aragorn could be impressed by Naruto's combat skills and his never - give - up attitude.
One interesting 'Lord of the Rings crossover vampire fanfic' could be 'The Blood - Ring Alliance'. In this fic, the vampires are from a different realm and find themselves in Middle - earth during the events of 'Lord of the Rings'. They initially try to stay out of the main conflict but end up getting involved in unexpected ways. It has some great character development for both the LOTR characters and the vampires.
One common theme is the clash of different cultures. For example, when Middle - earth characters meet those from other fictional worlds, there are often misunderstandings at first due to different values and ways of life.
