One common theme is adaptation. When Percy is small, he has to adapt to a whole new perspective of the world. For example, things that were once easy to reach are now out of reach, and he has to find new ways to do things.
A third theme could be self - discovery. Being small gives Percy a chance to see himself in a new light. He might discover new strengths or weaknesses. He could realize that he doesn't always need to be big and strong to be a hero, and that his intelligence and resourcefulness are just as important, if not more so.
One common theme is friendship. Percy has his friends in the railway world, and fanfictions often explore their relationships further. For example, how Percy helps his friends in tough situations or how they have fun together.
One common theme is Draco's redemption. Writers often explore how a younger or a different version of Draco can change his ways and become a better person. Another theme could be his relationships, like his friendship or even a romantic relationship with other characters in a new light, perhaps in a more innocent or unexpected way due to his'small' (again, depending on what this means in the context) state.
A common theme is self - discovery. Since Bella is now a small wolf, she has to figure out who she is in this new form. Another theme is acceptance, both of herself and by others in the fanfiction world. And there's often the theme of adventure as she navigates her new life with her wolf abilities.
A common theme could be the kitten's cuteness winning over others. In many small black kitten fanfictions, its small size and black fur make it an endearing character. People or animals who were initially hesitant or unfriendly towards it end up being charmed by its innocent and playful nature. For instance, a grumpy old cat might at first shoo the small black kitten away but later become its best friend after seeing how it tries so hard to catch a butterfly.
The theme of self - discovery is quite common too. Both Harry and Draco are on a path of self - discovery. For Harry, it might be about understanding his feelings for Draco which are different from what he expected. For Draco, it could be about finding a new identity outside of his family's expectations. And of course, friendship that turns into something more is a theme that runs through a lot of these fanfictions.
The theme of self - discovery is also quite common. As Tim grows up in the world of superheroes, he has to figure out who he is. Fanfictions often show his journey of finding his place, his values, and his own unique identity within the Bat - family and Gotham.
One common theme is friendship. Despite the harem aspect, the relationships often start as friendships. Another theme is adventure. Just like in the original Percy Jackson series, the fanfictions usually involve quests and battles.
Another theme is loyalty. The loyalty between Percy and Blackjack is unwavering, and fanfictions like to highlight this. For example, there are stories where Blackjack stays by Percy's side even in the most dangerous of situations, and Percy in turn does everything he can to protect Blackjack.
Common themes in 'Percy is a loner' fanfiction include the idea of independence. Percy has to fend for himself, which makes him more independent. There's also the theme of mystery. Because he's a loner, other characters might not know much about him, creating an air of mystery. Additionally, the theme of friendship in a different context. Sometimes, the fanfiction shows how Percy forms unique and deep friendships even though he's a loner. For example, he might meet someone who also feels like an outsider, and they form a special bond that is different from normal friendships.
One common theme is isolation. When Percy is betrayed, he often feels alone and has to face challenges by himself.
