In a Ben 10 and Rosario Vampire crossover fanfiction, there could be a plot where the technology of the Omnitrix gets combined with the magic in the Rosario Vampire world. Maybe Ben discovers a way to use alien powers to enhance the vampires' abilities or vice versa. There could also be a cultural clash aspect where Ben's human - alien experiences are very different from the human - vampire relationships in the Rosario Vampire world. This could lead to some interesting character development for both Ben and the Rosario Vampire characters as they learn from each other.
Well, a cool storyline might be that the villains from the Ben 10 universe somehow find their way to the Rosario Vampire world. And they start causing trouble by trying to take over the school or capture the vampires for their own evil purposes. Ben then has to team up with Tsukune and the other students to stop them. Or perhaps there could be a story where Ben accidentally gets turned into a vampire - like creature because of some magic in the Rosario Vampire world, and he has to figure out how to reverse it while still using his alien powers.
