Well, one interesting plot point is the clash of the different vampire abilities. In Twilight, vampires have certain powers like super speed and strength, and in TVD, vampires have different powers like compulsion. When combined in fanfiction, seeing how these powers interact or conflict can be really exciting. For example, if a Twilight vampire tries to use their speed against a TVD vampire who can compel them, it creates a whole new dynamic.
One interesting plot point is the clash of different supernatural powers. For example, the vampires' strength and speed in Twilight against the various abilities of the hunters in Supernatural like exorcising demons. Another is the cultural shock between the two universes. The vampires in Twilight have their own society and rules which are very different from the world of Supernatural.
Character relationships are also a big draw. Imagine Hermione Granger trying to study the biology of Twilight vampires or Edward Cullen being intrigued by the concept of magic wands. The way characters from the two universes form friendships, rivalries, or romances can be really engaging. For example, a love triangle between a Hogwarts student, a Twilight vampire, and a wizard can create a lot of drama and tension in the story.
Another plot point could be a love triangle. Imagine if one of the Cullen boys, like Edward, starts to develop feelings for Miley, while Jacob also has an interest in her. This would create a complex dynamic, different from the usual Twilight love stories. And Miley would be torn between two very different kinds of guys - a mysterious vampire and a warm - hearted werewolf.
One idea could be that a vampire from TVD ends up in Riverdale. Maybe Damon Salvatore finds himself in the small town for some mysterious reason. He could get involved with the mystery-solving that the Riverdale gang is always up to. He might use his vampire charm and powers to help or sometimes complicate things. Another plot could be that a character from Riverdale discovers the existence of vampires and werewolves like in TVD. For example, Jughead could be intrigued by these supernatural beings and start writing a story about them, which then draws the attention of the TVD characters.
The combination of their powers is also a great plot point. For example, Luffy's Gum - Gum Pistol combined with Naruto's Rasengan. Writers often come up with creative ways for them to use these powers together in battle against new and powerful enemies that neither could face alone. This creates really exciting action sequences in the fanfiction.
In seme Naruto crossover fanfiction, the adaptation of Naruto's character to a new world is always fascinating. He might have to learn new rules, magic systems, or ways of fighting. The seme relationships that develop can be a great plot point. For instance, if he crosses into a world with a strict hierarchy, his relationship with a high - ranking character could be full of conflict. He might challenge the norms of that world while also falling for that character in a seme relationship. This can lead to a story full of drama and character growth.
One of the coolest plot points is the cultural clash. The samurai - like code of honor in Bleach meeting the showmanship and bravado of the WWE world. Characters from Bleach might be confused by the over - the - top personalities in WWE, and vice versa. This can lead to some really humorous and also deep moments in the fanfiction. Another interesting aspect is when the WWE championships take on a new meaning in the context of Bleach's world. Maybe a championship belt becomes a symbol of power that both Bleach and WWE characters fight over, adding a new layer of significance to the WWE belts.
One interesting plot point is the clash of the two different worlds' technologies and magic. For example, in some fanfics, the Digimon's digital abilities interact strangely with the magic of Equestria. Another is the cultural exchange. Ponies are used to a very different social structure compared to the Digimon. So seeing how they learn from each other, like the Digimon learning about friendship in the MLP way, is fascinating.
A really interesting plot point is when the different skill sets of the characters are combined. For example, Buffy's combat skills against the supernatural and Gibbs' detective skills in the criminal world. In some fics, they use these skills to take on enemies that are both criminal and supernatural.
One interesting plot point is when Naruto uses his Rasengan in Middle - earth battles. It's a completely different world from his own, and seeing how this powerful ninja technique fares against the likes of goblins and trolls is exciting.
