The theme of change is also prevalent. Whether it's a change in the professor's teaching style, their view of the world, or the overall environment of the school due to the professor's presence. It makes for an interesting exploration of how one character can have a significant impact on the fictional setting.
One common theme is the professor's backstory. Writers often explore what made the professor who they are.
Another theme is redemption. Sometimes Magneto, who is often seen as the more radical one, is shown on a path of redemption, with Professor X guiding him in some way. It could be through understanding and forgiveness, like in some stories where Magneto realizes the error of his more extreme ways.
One common theme is the exploration of madness. Professor Pyg is a symbol of insanity, and fanfictions often show how Batman copes with such extreme madness. Another theme is the protection of Gotham's innocent. Batman is always trying to save the people from Professor Pyg's evil plans.
Another theme is the combination of different mythologies. Since Percy Jackson's world already has a rich base in Greek mythology, fanfictions often bring in other mythologies. For instance, some might incorporate Norse mythology, creating a more diverse and complex world for Percy to navigate as a professor.
One common theme is friendship. Ash and Professor Kukui often form a strong bond in these fanfictions. Another theme is adventure. They usually go on some sort of Pokémon - related adventure together.
Power dynamics is another theme. Hermione as a professor has a certain amount of power and authority, and Malfoy, coming from a once - powerful pure - blood family, has to adjust to this new situation. Their interactions are shaped by these power dynamics, like in some fics where Hermione uses her power to put Malfoy in his place or to help him grow.
Another theme is family legacy. Draco comes from a well - known pure - blood family. Fanfictions might explore how he deals with the expectations of his family name while being a professor. He could be trying to break free from some of the more archaic family traditions or uphold the positive aspects of his family's magical heritage.
The theme of competition is often seen. There are other junior professors or even senior ones who might see Ash as a threat or a rival. He has to compete for research grants, for the best students, and for recognition within the institution. Also, the exploration of different academic fields is a theme. Ash might start in one area but then get drawn into other related or even completely different fields, which broadens his perspective and the scope of the story.
Another theme could be his interactions with trainers. Writers might show how he helps or guides young trainers in their Pokemon journey, providing them with valuable knowledge and advice.
One common theme could be the exploration of a forbidden relationship. Since Hermione is a student and Professor Lemon (assuming it's a made - up professor in the fanfiction world) is in a position of authority, the idea of crossing that line is often explored.
