One great 'Vampire Diaries Crossover Fanfic' is 'The Vampire Diaries and Twilight: A Dark Union'. It combines the two vampire - filled universes in an interesting way. The author manages to blend the different vampire mythologies, like the way vampires are created and their powers in both series. It's a really exciting read for fans of both shows.
I really liked 'Crossed Paths'. In this fanfic, Castiel gets sent to Mystic Falls by accident. He teams up with Elena and Damon to fight off a group of rogue werewolves that are being controlled by a cross - dimensional witch. It's interesting to see how Castiel's angelic powers are perceived in the Vampire Diaries' world, and how he adapts to deal with the vampires and other supernatural beings there.
You can find 'Vampire Diaries Crossover Fanfic' on fanfiction.net. It has a large collection of fan - created stories, including many crossovers related to The Vampire Diaries.

One idea could be to cross it with another supernatural show like 'Teen Wolf'. The characters from both could team up to fight a common enemy, like an ancient and powerful vampire - werewolf hybrid. For example, Elena could use her charm and vampire skills, while Scott McCall could lead his pack in the fight.
One idea could be having Elena from 'The Vampire Diaries' meet Bella from 'Twilight'. Maybe they discover that they have more in common than they thought, like their love for vampires who are trying to resist their more primal instincts. They could team up to help their vampire boyfriends deal with some common threats in both their worlds.
Imagine if Elena Gilbert was somehow connected to an Infinity Stone. This would draw the attention of Thanos, but also the Avengers. The Vampire Diaries characters would have to protect Elena while also dealing with the fact that the Avengers are now in their small town. There could be a lot of mistrust at first, but as they learn more about each other's motives and capabilities, they form an alliance to keep the Infinity Stone out of Thanos' hands.
Alice from 'Alice in Wonderland' could be an interesting addition. Her dream - like perception of the world could contrast with the often - dark and brooding atmosphere of 'The Vampire Diaries'. Maybe she could see things that the other characters can't and help them in unexpected ways.
I really like 'A New Dawn in Mystic Falls'. This fanfic takes the story in a different direction. It has a great plot where the characters have to face new threats that are not in the original series. It's full of twists and turns that keep you hooked from start to finish.
Well, a frequent theme is the clash of different cultures. In a Vampire Diaries and Harry Potter crossover, you have the magical culture of Hogwarts clashing with the vampire - based culture of Mystic Falls. This can lead to misunderstandings and conflicts that drive the story forward. Also, survival is a big theme. In many crossovers, the characters have to find a way to survive in a new and more dangerous world created by the crossover. For instance, in a Vampire Diaries and Buffy the Vampire Slayer crossover, the vampires from Vampire Diaries might have to adapt to the slayer - filled world of Buffy or face being staked.
Yes, there are some interesting 'Naruto Vampire Diaries' crossover fanfics out there. You can find them on various fanfic websites. Some might focus on Naruto characters getting involved in the Vampire Diaries' supernatural world, like Naruto having to deal with vampires and witches. Others could be about a Vampire Diaries character ending up in the Naruto universe and trying to adapt to things like chakra and ninja skills.
