A common Harry Potter crossover in adult fanfiction is with the Discworld series. The satirical and complex world of Discworld can create some really unique storylines when combined with Harry Potter. In these crossovers, the rules of magic from both universes often collide and create new and exciting plot developments. Some also explore the crossover with the Buffy the Vampire Slayer universe, where the fight against dark forces takes on new dimensions.
Well, some might include a crossover with the Star Wars universe. Picture Jedi in Hogwarts or Harry Potter characters using lightsabers. Also, a crossover with the Chronicles of Narnia could be interesting. The magical creatures and different worlds in Narnia could blend well with the wizarding world of Harry Potter. However, it's important to note that adult fanfiction might contain more complex and mature themes that not all readers may enjoy.
