Well, a great plot could involve a magical experiment gone wrong that links the two universes. Dracula Untold's vampires start to appear in Hogwarts. The students are in panic. Harry, being the brave one, decides to seek help from the old vampires in Dracula Untold's world. He hopes to find a way to send them back and in the process, discovers some ancient magic that is common to both worlds.
One possible interesting plot could be that Dracula is somehow transported to the wizarding world of Harry Potter. Maybe the Ministry of Magic mistakes him for a dark wizard at first. But then they realize he has unique powers that could be used either for good or bad. Harry and his friends might initially be scared of him but then try to understand him and his vampiric nature.
Perhaps in the fanfiction, Voldemort tries to make an alliance with Dracula. He thinks that Dracula's immortality and his vampire army could help him in his quest to take over the wizarding world. But Dracula has his own motives. Harry and his friends find out about this alliance and have to not only fight against Voldemort but also figure out a way to stop Dracula from using the wizarding world for his own vampiric desires. They might learn new spells and potions to combat the vampires.
