A really cool 'Lord of the Rings' crossover fanfiction is when it crosses with the DC Universe. Superman or Wonder Woman in Middle - earth would be quite a sight. They could use their powers to fight the forces of Sauron. This kind of crossover often explores how the extraordinary powers from the DC side would impact the more medieval - style world of 'Lord of the Rings'.
One idea could be a vampire character who is drawn to the power of the One Ring. Maybe this vampire, being a creature of the night and often associated with darkness and power -hunger, sees the ring as a means to gain ultimate power in Middle - earth. For characters, you could have a half - vampire, half - elf who struggles with their dual nature while being caught in the events related to the ring.
To write a good vampire Lord of the Rings crossover fanfiction, you need to focus on character development. If you're introducing a vampire lord, make him a complex character. Give him motives that are more than just 'I want to rule the world'. Maybe he has a tragic past that led him to his current state. Also, make sure the language you use fits the tone of both worlds. The Lord of the Rings has a very specific, almost archaic style of speaking in places, and your vampire characters should also have a voice that is consistent with their nature. And don't forget about the pacing. You don't want to rush the story, especially when it comes to the big moments like battles or revelations about the ring.
One way it could work is by having Naruto characters in Middle - earth. For example, Naruto with his shadow clone jutsu could be a great asset in the battles against Sauron's forces. He could create clones to confuse the orcs and trolls. Meanwhile, characters from 'Lord of the Rings' could learn from Naruto's ninja skills. Frodo might pick up some stealth techniques from Naruto's training.
One common theme is the clash of different cultures. Buffy comes from a modern world with a certain set of values and fighting styles, while Middle - earth has its own ancient and more traditional ways. So, the stories often explore how these differences play out when she arrives there.
A possible crossover would involve Merlin's struggle with the dark forces in Middle - earth. He is used to fighting against Morgana and her minions in Camelot, but in Middle - earth, the enemies are Sauron and his armies. His skills in magic and strategy would be put to the test. He could also form an alliance with Aragorn, sharing his knowledge of leadership and magic to help Aragorn in his quest to become king.

Merlin and Frodo could have an interesting interaction. Frodo, burdened with the One Ring, might seek Merlin's advice on how to resist its power. Merlin, having dealt with dark magic before, could offer some insights.
Well, consider Naruto's relationship with Gandalf. Gandalf would be intrigued by Naruto's chakra and his ability to perform what seems like magic without a staff or a spell book. Naruto, on the other hand, would look up to Gandalf as a wise and powerful figure. The Uchiha clan members, like Sasuke, might find kinship with the elves due to their refined skills and long - lived nature. And the interactions between the Naruto characters and the dwarves could be full of banter, as the dwarves would be amused by the strange abilities of the ninjas.
The plot could involve Naruto characters in the Middle - earth. Maybe Naruto with his shadow clone jutsu could be used in battles against orcs. For example, he could send a horde of clones to confuse the enemy. And Sasuke with his Sharingan might be able to detect the hidden threats in the dark forests of Middle - earth. It would be a really interesting mix of the two universes' combat styles and magic systems.
