A common theme is the clash of different powers. The magic from Harry Potter and the superpowers of the Avengers often collide and combine in interesting ways.
The exploration of new worlds is also a theme. Avengers get to experience the magical world of Hogwarts and vice versa. This leads to a lot of cultural and power - based exchanges. For instance, Thor might be amazed by the magic of the wizarding world while Hermione might be in awe of his god - like powers. It's about the discovery and adaptation in a crossover setting which can be really exciting for readers.
Another theme is the idea of different cultures coming together. The characters from Sunnydale have a very different upbringing and set of values compared to those in the wizarding world. This can lead to some interesting character dynamics, like Hermione trying to understand Buffy's more street - smart ways or Xander being in awe of the magical grandeur of Hogwarts.
One common theme is the clash of different power systems. In both The Vampire Diaries (TVD) and Harry Potter (HP), there are unique forms of power. In crossovers, it's interesting to see how the magic of HP and the supernatural abilities in TVD interact. For example, how would a vampire react to a Patronus charm? Another theme is the exploration of different cultures. The wizarding culture in HP and the vampire - werewolf - witch culture in TVD are very different, and crossovers often explore how characters from one world adapt to the other.
A common theme is teamwork. Since it's a crossover, different characters from different universes or groups have to work together. For example, in an Avengers and X - Men crossover, they need to combine their powers and strategies.

And of course, there's often a big bad villain that they have to defeat together.
One common theme is redemption. Loki is often portrayed as seeking redemption for his past misdeeds while working with the Avengers. Another theme is the clash of personalities. The Avengers have very different personalities from Loki, and this often leads to interesting conflicts and resolutions. For example, Thor's relationship with Loki adds an extra layer of drama.
One common theme is the clash of ideologies. Venom has a more chaotic and anti - hero approach compared to the Avengers' heroic and morally upright stance. Another theme is redemption. Sometimes Venom is on a path to redeem himself through his interactions with the Avengers.
One frequent theme is the exploration of different universes. How would the two universes of Lucifer and the Avengers coexist or interact? Some fanfictions also focus on the character relationships. For instance, how would Iron Man react to Lucifer's devil - may - care attitude? Or how would Thor, a god in his own right, interact with Lucifer? It's all about mixing the distinct personalities and story elements from both franchises. There can also be themes of redemption, where Lucifer might find a new path or purpose while interacting with the Avengers.
