Another theme is the exploration of good and evil. Esdeath is often seen as a morally ambiguous character from 'Akame ga Kill', and in the Harry Potter universe, she is placed in a new context of good and evil. So, fanfictions usually deal with how she either adapts to the more clearly defined good - vs - evil concept in Harry Potter or challenges it.
The theme of adaptation is also quite common. Esdeath is suddenly in a completely different world, and fanfictions often show how she tries to make sense of the new rules, cultures, and social structures in the Harry Potter world. This can range from her trying to understand the House system at Hogwarts to dealing with the Ministry of Magic.
One common theme is the struggle with their different personalities. Tatsumi is often portrayed as more kind - hearted, while Esdeath is cruel. So when she becomes pregnant, there might be a theme of her learning to be more empathetic. Another theme could be the protection of the unborn child, with Tatsumi taking on a more protective role.
One common theme is the idea of redemption. Often, the OC tries to bring out a softer side of Esdeath, as if redeeming her from her cruel ways. Another theme is the power dynamic. Since Esdeath is a powerful character, the relationship with the OC often explores how power affects their interactions.
Well, it could be a very interesting mix. Esdeath is a rather strong and somewhat cruel character from 'Akame ga Kill!'. If she raised Harry Potter, he might grow up to be much more of a fighter in a different sense. Maybe he'd be more ruthless in dealing with his enemies at Hogwarts, instead of just using magic for defense and the occasional prank. He could be trained in combat skills along with magic, making him a very formidable wizard.
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.
One common theme is adventure. Combining the action - packed world of 007 with the magical adventures of Harry Potter makes for some thrilling stories.
A lesser - known but really interesting one is 'When Esdeath Meets the Marauders'. It's set in the past of the Harry Potter universe, and Esdeath's encounter with the Marauders - James, Sirius, Remus, and Peter - leads to some very unexpected events and alliances. Her cold - blooded nature clashes and also meshes with the more mischievous nature of the Marauders.
Love is a very common theme. Their relationship, from the initial attraction to the deep, abiding love they share as a married couple. Another theme is family. Fanfictions often explore how they raise their children and the Potter family values.
Common themes include the exploration of Hogwarts in different eras. Since James was at Hogwarts before Harry, fanfictions might compare and contrast the two times. For example, the different social dynamics among students, the teaching methods of the professors. Friendship is also a big theme. James had his group of friends, the Marauders, and Harry had his own friends. Fanfictions may show how these friendships are similar or different. Additionally, the fight against the Dark Arts is a common theme. Both James and Harry faced dark wizards, and fanfictions can explore their different approaches to this fight.
One common theme could be family bonds. Since they both have the Potter name, exploring their family connection and how it affects their relationship in the wizarding world. Another might be the continuation of the Potter legacy, like how they uphold or change the family's reputation.
A major theme is the exploration of the past. Harry never really got to know his father properly. So in fanfiction, writers often take the opportunity to delve into James Potter's life. This could include his time at Hogwarts, his relationship with Lily, and how all of that shaped Harry. It's also common to see themes of redemption, especially if the fanfiction takes a different turn on James' character, perhaps showing him making amends for any mistakes he made in his youth.
