Well, time - travel is a fairly common theme. Writers like to send characters back in time to change certain events in the wizarding world's history. It can be really interesting to see how one small change can have a huge impact on the future. Friendship is also explored in different ways. There are fanfictions that show how the relationships between the main trio could have developed differently. And of course, the discovery of new magic is a theme. Fanfic authors often come up with their own unique spells and magical artifacts for their stories.
Some popular themes are vampire - hunter relationships. This can be a love - hate relationship where the hunter is initially out to kill the vampire but then things change. There's also the theme of vampire families. How they interact with each other, raise their young (if vampires can have young in the fanfic), and pass on their traditions. Additionally, the theme of the vampire's powers and how they use or abuse them in different situations is often explored in vampire verse fanfiction.
One popular theme is the complex relationships between Alphas, Betas, and Omegas. For example, the power dynamics in Alpha - Omega relationships, where Alphas are often seen as dominant. Another theme is the exploration of the unique biology and instincts of each type. Like how Omegas go into heat and how Alphas respond to that. Also, the struggle for equality among the different types in a society that often discriminates based on ABO status is a common theme.
One popular theme is the 'what - if' scenarios. For example, what if Harry had been sorted into Slytherin instead of Gryffindor? Another common theme is romance, like Harry and Hermione getting together instead of Ron and Hermione. There are also a lot of fanfictions that explore the backstories of minor characters in more detail.
