There could be new characters created specifically for this fanfiction that are central to the merging concept. For example, a character who has the ability to control the merged magic or someone who is the key to uniting different groups of wizards that were brought together in this fan - made story.
It might be a fanfiction that merges different time periods of the Harry Potter world. For example, it could blend the events of the first wizarding war with the time of Harry Potter's schooling. This would create a whole new set of plot twists and character developments as characters from different eras interact.
I'm not sure specifically as there could be many different 'merging Harry Potter fanfics'. Generally, it might be about combining different elements from the Harry Potter universe, like different storylines, characters from various parts of the series, or different fan-created concepts within the wizarding world.
The main characters are usually James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. James is the confident and sometimes arrogant leader of the group. Sirius is the rebellious and loyal friend. Remus, the werewolf, is often the more reserved and intelligent one. Peter is the follower, though his character can be explored in different ways in fanfiction.
Hermione could also be a main character in this fanfiction. Her intelligence combined with the new element of wings could lead to some really interesting plot developments. She might study the magic behind the wings and find ways to use it to help her friends.
There could also be other characters from the 'Harry Potter' universe like Hermione Granger and Ron Weasley. Hermione might help Harry and Kasanoda with her vast knowledge of magic and books. Ron could add his loyalty and humor to the story. They might be involved in the plot, either helping Harry and Kasanoda or causing some comical misunderstandings.
I'm not sure specifically as it depends on how the fanfiction is written. But surely Harry Potter would be one of the main characters. There might also be a character related to the 'walker' concept who could be a central figure, perhaps someone who has a special connection to this 'walker' identity and interacts closely with Harry and his friends.
It's possible that new characters are introduced in the 'harry potter and the vella fanfiction' as well. They could be characters from other magical regions or families that have a connection to the main plot. Maybe there's a mysterious new student who arrives at Hogwarts with a strange power or a hidden agenda. This new character could interact with Harry and his friends in various ways, either as an ally or an adversary, adding more depth and complexity to the story.
It's likely that Harry Potter himself remains a main character. Since it's a fanfiction related to the Harry Potter series, he would probably be at the center of the story, dealing with the devil - related elements. Hermione and Ron might also be main characters, as they are Harry's closest friends in the original series and would likely be involved in whatever strange events are happening in this fanfiction.
There could be a character who is a half - Ogron, half - wizard. This unique character could have a complex identity, not fully accepted by either the Ogron community or the wizarding world. They could become an important part of the story, perhaps being the key to resolving a conflict between the two groups. Their struggle with their identity and their place in the world could be a central theme in the fanfiction.
Well, Harry Potter himself could still be a main character. He might be leading the revolution, using his fame and experience to inspire others. Hermione would also be important as she could be the brains behind the strategic planning, coming up with ideas on how to change the system.
