Well, it depends on the specific ghost story. Barty might be a malevolent ghost, a helpful spirit guide, or someone related to the haunted place. Without knowing the details of the story, it's difficult to give a precise answer.
Sirius Black would be an interesting character to put in the fanfiction. He has his own history with the dark arts and could offer a different perspective on Barty's actions. And Neville could also be included. His growth and courage could inspire both Harry and Barty in different ways. Neville might stand up to Barty in a situation where others might not, showing his new - found confidence.
One common theme is redemption. Barty Crouch Jr. was a dark character, and many fanfictions explore the idea of him being redeemed through his interactions with Hermione. For example, in some stories, Hermione's kindness and wisdom make him question his evil ways.
One common theme is the clash of good and evil. Hermione represents the side of good and Barty Crouch Jr. is typically associated with the dark side. Their interactions often explore how Hermione might try to redeem him or at least understand his actions.
Perhaps a fanfiction where Barty, after being exposed, somehow has a chance at redemption and forms an unlikely alliance with Harry to fight a greater evil that threatens the wizarding world. They could learn from each other's strengths and weaknesses. For example, Harry's pure heart could influence Barty to turn away from his dark past.
The person who killed Barty Crouch in fanfiction is highly unpredictable. It could be a dark wizard who emerges from the shadows or a close ally with a hidden agenda.
There's also 'A Different Encounter' which delves into how Hermione's intelligence might both intrigue and confound Barty Crouch Jr. In this fanfiction, their meetings are filled with tense exchanges as Hermione tries to figure out his true motives. The story takes some interesting twists and turns as it progresses.
One common theme is redemption. Since Barty Crouch Jr was a Death Eater with a lot of wrongdoings, many fanfics explore the idea of him finding redemption through his connection with Harry Potter. Harry is often seen as a symbol of hope and goodness, so it makes sense that he could be the catalyst for Barty's change.
One major plot change could be Hermione's attitude towards the Ministry. Since Barty Crouch is associated with the Ministry, she might have a more complex view of it. Maybe she'd be more involved in Ministry affairs earlier on.
Yes, there are some interesting ones. You can check out fanfiction platforms like Fanfiction.net or Archive of Our Own. Some of these fics might explore unique storylines where Hermione is Barty Crouch's daughter, such as how it would change her relationships in the wizarding world, her role at Hogwarts, and her connection to the events related to Barty Crouch in the original series.
