The theme of family also plays a big role. Even though Hadrian may be a bamf (bad - ass mother - f*cker), he still has to deal with his family legacy, whether it's the Potter name or other family ties. This can create interesting storylines about how he honors or overcomes his family's past.
I also like 'Bamf Hadrian Potter and the Lost Prophecy'. It presents Hadrian in a really cool way. He is not only strong magically but also very intelligent. The story weaves an interesting narrative around him trying to solve the mystery of a lost prophecy and his journey in doing so.
One common theme is acceptance. The characters often have to come to terms with the mpreg situation which is not the norm in the wizarding world. Another theme is the strength of the 'bamf' characters. They usually show great resilience in the face of the challenges that come with mpreg, like dealing with the reactions of others.
One major theme is family legacy. Hadrian has to deal with the great reputation and secrets of the Peverell family. Adventure is also quite common. He often goes on quests or travels to different places in the magical world. There's also the theme of friendship. He forms bonds with other characters as he navigates his new life.
One common theme is family legacy. Since Hadrian is related to the Black family, many fanfictions explore how the family's past actions, reputation, and secrets impact him. Another theme is self - discovery. Hadrian often has to figure out who he really is in relation to his newfound family ties.
One common theme is empowerment. Since it's about a female Harry, there's often a focus on her being strong and in control. Another theme is changing the status quo of the wizarding world. A female Harry might not follow the same rules or traditions as the male Harry did.
Power - up is a very common theme. Xander goes from being the 'normal' one in the group to having some extraordinary powers or skills. Also, friendship is often explored. His relationships with Buffy, Willow, and the others are either strengthened or tested as he becomes a bamf. In some stories, his newfound status makes his friends see him in a whole new light, which can be both positive and negative for their friendships.
One common theme is Merlin's hidden power being revealed to the knights. For example, in many fanfictions, Merlin shows his magical abilities in a big way to save the knights from a dangerous situation, like a powerful enemy attack.
One common theme is the clash of cultures. For example, when Naruto crosses into a different universe like the Star Wars universe, his ninja culture and the Jedi culture can be very different. This creates interesting conflicts and also opportunities for Naruto to learn and grow.
One common theme is redemption. Since Percy had his issues in the original series, many fanfictions focus on him redeeming himself in a bamf way, like standing up to powerful enemies or making up for past wrongs.
One common theme is his acrobatic skills. Fanfics often showcase how he uses his agility in combat. Another theme is his loyalty to Gotham. He's always there to protect the city.
