In the original series, Harry Potter was a hero with a set lifespan, but in fanfiction as an immortal, he becomes more of an eternal protector. He has the ability to safeguard the wizarding world for centuries, not just a few years as in the original story.
One role could be as a clue. In a fanfic that combines the two universes, an azalea might be the key to solving a mystery. Maybe it has a hidden message written on its petals in a language only a few can understand. In the Harry Potter side, it could be related to ancient runes, and in Supernatural, it could be a sign from an angel or demon.
In the fanfiction, Naruto's immortality could make him a key figure in resolving long - standing conflicts. He has the time and the power to study both the wizarding and ninja worlds deeply. So he could use his knowledge to find solutions to problems that have been plaguing the wizarding world for ages, like the fight between pure - bloods and half - bloods or the threat of dark wizards. His presence would bring a new dynamic to the story as he doesn't have the same limitations as the regular Harry Potter characters in terms of lifespan and the type of power he wields.
He could be a mentor. Since he's immortal, he has a vast amount of knowledge and experience. He could teach young heroes or anti - heroes about the value of life and how to use their powers responsibly. For example, he could guide Robin on how to be more strategic in combat, sharing his own experiences from fighting Voldemort.
In a lot of Harry Potter fanfiction, Cerberus can be a plot - driving element. Its presence can create tension and suspense. For example, if a group of characters need to retrieve something from a place guarded by Cerberus, they have to figure out how to get past it. This can lead to all kinds of creative solutions and adventures in the story. It might also be used as a way to show the different magical abilities of the characters as they attempt to deal with it.
Beauxbatons can play a variety of roles in fanfiction. Sometimes it's a place that provides a contrast to Hogwarts. For instance, its architecture and setting might be described as more opulent. It can also be a source of new characters who enter the main story set in the Harry Potter universe and bring new plotlines or magical knowledge.
Inspector 13 could play a detective - like role, solving magical mysteries in the fanfiction.
The mirror can also be a symbol of truth in Supernatural fanfiction. It shows things as they really are, even if the characters don't want to see it. So, if there's a spell or a mystery involved, the mirror might be the key to revealing what's really going on. Maybe it reflects the true identity of a shapeshifter or shows the location of a hidden supernatural object.
Well, in fanfiction, compared to the original books, Harry's role as champion can be a lot different. He may be involved in more complex political situations within Hogwarts. In the books, the focus was more on the tournament tasks, but in fanfiction, he could be dealing with power struggles among different groups of students or teachers while being the champion.
In fanfiction, his time in Azkaban might be more about his internal struggle and growth. He may use his time to discover new magical abilities or gain a deeper understanding of the wizarding world's politics. In the original series, he never actually experiences Azkaban, so this is a completely new scenario in fanfiction.
Autism can play a significant role in the relationships within the fanfiction. An autistic character could have a friendship with Hermione, for example. Hermione, being the studious and understanding type, could help the autistic character navigate the social and academic parts of Hogwarts while the autistic character could offer Hermione new insights into magic based on their different perspective. This kind of relationship dynamic can make for a very engaging and unique fanfiction.
