One common theme is self - discovery. Since Abraham Potter is a character in a magical world, many fanfictions focus on him finding out more about his own powers and identity. Another theme is friendship. Writers often explore the friendships he could form with other characters in the wizarding world.
Growth is another theme. The characters usually develop over the course of the fanfiction, learning from their experiences with each other. This could be personal growth, like becoming more confident, or growth in their relationship, such as learning to communicate better.
Redemption can also be a theme. Maybe one of them has made a mistake in the past, and through their relationship with the other, they find a way to redeem themselves. This adds an interesting layer to their characters and the story, as it shows their growth and the power of their connection.
The theme of perseverance also shows up. Lincoln faced many setbacks and challenges during his life and presidency, and fanfictions can tell stories of how he overcame these difficulties, whether it was political opposition or personal tragedies.
A common theme is his leadership during the Civil War. Fanfics often explore how he made difficult decisions.
One more theme that can be found is the battle between good and evil. Given the Potter family's history of being involved in the fight against dark magic, Dorea may find herself in situations where she has to choose the right side. This can lead to some really intense and exciting storylines, with her facing off against dark wizards or having to make difficult moral decisions.
Common themes include the power of love and loyalty. In some fanfictions, Snape's love for Lily extends to his relationship with Potter in unexpected ways. Another theme is the struggle between good and evil within their own characters. Potter has his own inner demons to face, and Snape is often seen as a morally grey character. And there's the theme of family, as Potter is an orphan and Snape has his own complicated family history, which can be explored in relation to their relationship.
Love and relationships are often explored as well. It could be romantic love, or the love between friends and family. Some fanfictions focus on how Alexandra's relationships develop over time and how they shape her character. Also, the struggle between good and evil is a common thread, with Alexandra usually on the side of good, fighting against various forms of malevolence in the wizarding world.
One common theme is self - discovery. Audrey often has to figure out her own identity and powers. For example, in many stories she realizes she has a special connection to a certain type of magic.
Love and sacrifice are also prevalent themes. We see how the love of Lily Potter saved Harry in the original series, and fanfiction often expands on this idea of love being a powerful force. There are also fanfictions that explore the idea of redemption for characters like Draco Malfoy, showing that even those on the wrong side can have a chance at changing and making amends.
Another theme is exploration. Many fanfictions have Potter exploring new places, either within the wizarding world or even outside it. For example, he might discover hidden magical realms. This adds an element of adventure to the stories.
