One common theme is redemption. When Harry returns from the dead, he often has a chance to right the wrongs that happened before his death. For example, he might try to save a character who died in the original series.
It could mean that in the fanfiction, there's a concept of the dead returning in a more metaphorical sense. Maybe the memories or the influence of dead characters return to haunt or guide the living ones. For example, the ghosts of Harry's parents could play a more active role in the story than they do in the original books, coming back in a way that affects Harry's decisions and the overall plot.
The return of the dead can also cause conflict among the characters. Some might be skeptical or even afraid of the resurrected character. They could think it's some sort of dark magic at play. Take Hermione for instance. She might be initially cautious and want to investigate how and why the character has returned, which could lead to tension within the group of friends.
Harry Potter himself would most likely be one of the main characters. Since it's related to the Harry Potter universe, he would be at the center of things. Hermione and Ron would also probably be involved, as they are his closest friends. Additionally, characters like Dumbledore might make an appearance, even if he was dead in the original series. His wisdom could be crucial in dealing with the situation of the dead returning.
One possible interesting plotline could be how the return of the dead affects the existing relationships in the wizarding world. For example, if a beloved character who died in the original series returns, how do their friends and family react? Do they hold grudges for being left behind? Another plotline might involve the power dynamics. Maybe the returned dead have some new powers or knowledge that they bring back, which could disrupt the balance between good and evil in the wizarding world.
One interesting plot could be that after Harry's death, his friends find a powerful ancient spell in the Room of Requirement. This spell was created long ago by a powerful wizard who also faced death unfairly. They manage to perform the spell and it brings Harry back. But he returns with some new powers that he has to learn to control. He also has a connection to the spirit world now, which helps him in his new battles against the remaining dark forces.
The main difference is the addition of Dead Apostles. In regular Harry Potter fanfiction, the focus is usually on the existing elements of the wizarding world like Hogwarts, the Ministry of Magic, and the well - known magical creatures. But in 'Harry Potter Dead Apostle fanfiction', Dead Apostles bring in a whole new kind of threat. They often have different powers and motives compared to the regular villains in the Potterverse.
His friends might be overjoyed at first. But then, they could also feel a bit of unease. For example, Hermione might be worried about the implications of his return and how it fits into the laws of magic they know. Ron, on the other hand, might be more focused on just having his friend back and want to jump right back into their old adventures.
The original series has very strict rules about life and death. In the original, the dead are not to be controlled. But in this fanfiction, Harry having such a power is a huge deviation. It allows for a much darker and more complex exploration of magic. In the original, Harry's power comes from his own skills, courage, and the help of his living friends and mentors. Here, he's tapping into a power that is considered taboo.
One interesting 'Harry Potter return from dead' fanfiction could be 'The Resurrected Boy'. In this fic, Harry comes back with newfound powers and a deeper understanding of the wizarding world's secrets. It's a great read for those who love to explore alternate storylines.
