Sure. There are also fanfictions that delve into their family relationships. Maybe Draco has a change of heart and starts to see Harry and Neville as true brothers, and they all support each other through difficult times, like dealing with the aftermath of the war.
One common theme is redemption. Draco often has a chance to redeem himself and form a closer bond with Harry and Neville. Another theme is friendship across house divides. Since they are from different houses, their growing friendship is a popular plot point.
Yes, there are quite a few interesting ones. You can start by looking on fanfiction.net. Some of them explore how their relationship as brothers would change the story's dynamics, like in adventures at Hogwarts or during the fight against Voldemort.
One main theme is family. It shows how their brotherly bond can be a source of strength. Another is the impact on the wizarding war. Their combined efforts could change the outcome.
The popularity also comes from the fact that both Harry and Neville are well - loved characters. Combining them in fanfiction allows for new and exciting storylines. For example, they could go on adventures together that were not part of the main plot, or support each other in ways that are unique to their new relationship.
One great 'Harry Potter' fanfiction with Neville and Draco is 'The Unlikely Bond'. In it, they are forced to work together on a school project. At first, they clash due to their different personalities and house loyalties. Draco is his usual snobbish self, while Neville is shy but determined. As the story progresses, they start to understand each other better. Neville shows Draco the importance of kindness and hard work, and Draco helps Neville become more confident in standing up for himself.
I really like 'The New Alliance'. In this fanfiction, Neville and Draco team up to fight against a new dark force that emerges in the wizarding world. Their partnership is unexpected but it works really well. Draco uses his family's resources and Neville uses his Gryffindor courage. It's a fast - paced story full of action and adventure.
One great 'Harry Neville Brothers' fanfiction is 'The Bond Beyond Houses'. It explores their friendship in a post - Hogwarts world, showing how they support each other in rebuilding the wizarding community.
In many of these fanfictions, Draco often starts as a more guarded character. But as Neville's pregnancy progresses, he becomes more protective and caring. For example, in 'The Unlikely Bond', he gradually sheds his Slytherin cold - exterior. Neville, on the other hand, grows in confidence. His pregnancy makes him more assertive about his relationship with Draco.
I really like 'Draco's Redemption and Neville's Forgiveness'. In this fanfic, Draco is trying to make up for his past wrongs during the war, and Neville is the one who helps him through it. It delves deep into their emotions and how they grow as characters through their interactions.
