One of the well - known characters is Sirius Black. In rebellious fanfiction, he might return in a more powerful way and help Harry in his rebellious endeavors. His knowledge of the dark side of the wizarding world and his own experiences as an outcast could be very useful. Neville Longbottom can also be a prominent figure. He could grow into a strong ally of Harry's rebellion, using his new - found confidence to stand up against the things that are wrong in the wizarding world. And Luna Lovegood, with her unique perspective on the wizarding world, could inspire Harry to think outside the box and rebel in more creative ways.
Definitely Ginny Weasley. She is often portrayed as a strong - willed character in fanfiction. She could be right beside Harry in his rebellions, using her own charm and magic skills. Fred and George Weasley are also important. Their pranks could take on a more political or rebellious slant in fanfiction. They could use their creativity to disrupt the systems that they think are unfair. And Severus Snape, in some cases, might be a complex character in rebellious fanfiction. He could have a change of heart and support Harry's rebellious actions, despite their past differences.
I think Dobby could be an important character. Since Harry is raising himself, Dobby might take it upon himself to secretly help Harry. He could provide some food and small comforts when Harry is all alone. Another character could be Hedwig. She would be more than just a pet; she could be Harry's only true companion, helping him in small ways like delivering messages or even warning him of danger.
Neville could be in it too. He might be initially shocked to see Harry in such a state but then tries to help by using some of his herbology knowledge to make a potion to counteract the drunkenness. And Malfoy could show up, taking the opportunity to mock Harry until Harry, in his drunken craziness, does something that scares Malfoy off. Also, Hagrid would surely be around, being concerned about Harry and trying to get him to rest in his hut.
Hermione would most likely be one of the main characters. She's always observant and caring towards Harry. So when she notices something is off with Harry, she would do everything in her power to figure out what's wrong and help him. She might use her extensive knowledge of magic to find a solution to his emotional distress.
One interesting character could be an ancient magical creature that befriends Harry Crow. This creature could have its own set of powers and knowledge that helps Harry Crow in his adventures. Another could be a new student from a far - off land who has different magical traditions. Their interactions with Harry Crow would be fascinating as they introduce new ideas and ways of using magic into the story.
The dragon, of course, is a major character. It could be named something unique like 'Fyrstorm'. There might also be Hermione and Ron. Hermione would probably be worried about the legality and danger of raising a dragon, while Ron might be both scared and a bit excited about it.
Hermione is often a common character. In these fanfictions, she might play a different role. For example, she could be the one to discover Harry's unique upbringing and help him understand how it makes him different from other wizards. Ron could also be there, and his friendship with Harry might develop in new ways. Maybe he's a bit more in awe of Harry's magic since he was raised by more powerful magic sources.
Hermione would surely be involved. She could be Harry's research partner, helping him find relevant medical information in books and scrolls. Her intelligence and thirst for knowledge would be very useful in exploring new areas of medical magic. Another character could be Madam Pomfrey. She could be Harry's mentor, teaching him the basics of wizarding medicine and guiding him in his new role as a medic.
Hermione is often a common character. Since she is Harry's closest friend, she usually plays an important role in helping Harry navigate the past. She might use her vast knowledge of magic and history to figure out why Harry was summoned and what they need to do next.
Hermione is often in these fanfictions. She might help Harry understand the more complex magical aspects related to his broomstick. For example, she could research ancient spells that were once used to enhance broomstick speed and try to apply them to Harry's broom.
Hermione is often a key character. She might stand by Harry's side, using her intelligence and loyalty to help him through the tough times. She could be the one to encourage him to keep going and not let the disownment break him.
