Definitely Ginny Weasley. She has her own growth story, and in fanfiction, it can be elaborated. She goes from being Harry's love interest to a strong, independent witch. Seamus Finnigan could also be a focus. He has a bit of a fiery personality, and fanfiction can show how he matures. And Fred and George Weasley. Their pranks and how they grow into more responsible but still fun - loving wizards can be great to write about.
I think Cho Chang is an interesting character for coming - of age fanfiction. She has a complex relationship with Harry, and in fanfiction, her own story of growing past heartbreak and finding her place in the wizarding world can be told. Then there's Hagrid. He's like a big kid at heart, but fanfiction can explore how he helps the younger students come of age. And Dobby the house - elf. His loyalty and how he might influence the young wizards' growth can be a fascinating aspect to focus on.
Definitely Snape. His complex character with his love for Lily and his role as a double agent has so much potential for exploration through memories. Harry himself is also interesting as his memories can uncover more about his family and his own growth. And Dumbledore, his past is full of mystery and his memories could reveal many secrets about his actions and motives.
There's also 'Dust' which is a more unique take on the coming - of - age theme in the Harry Potter universe. It follows a character who has been on the outskirts of the main story but gradually finds their place and purpose. It's a story about self - discovery, acceptance, and growing into one's power.
Leonidas from '300' would be a great character to focus on. Imagine his reaction to the magic of the Harry Potter world. He's a fearless leader, and seeing him interact with wizards and magical creatures would be fascinating. He might see the magic as a new weapon or a strange form of sorcery that he has to either embrace or fight against.
Luna Lovegood is an interesting choice. She has such a unique perspective on the world, and in the post - war era, she could be involved in exploring the more hidden and strange aspects of the wizarding world that were overlooked during the war. Maybe she discovers new magical creatures or lost spells.
One popular theme is friendship. In fanfiction, it often delves deeper into the friendships between Harry, Ron, and Hermione. For example, how they support each other during difficult times at Hogwarts. Another theme is self - discovery. As the characters come of age, they learn more about their own strengths and weaknesses. For instance, Harry might discover new magical abilities or aspects of his personality. Magic exploration is also a theme. Fanfiction authors may create new spells or magical creatures that the characters interact with as they grow up in the wizarding world.
The Weasley twins are always fun to write about. Their pranks could be taken to a whole new level in fanfiction. For instance, they could create a prank that accidentally affects the entire academy, like a spell that makes everyone's robes change colors every time they sneeze. And then they have to find a way to reverse it before they get into too much trouble.
Harry Potter, of course. He has the most potential for character development in time travel scenarios. He can interact with his parents, for example, which would be a very emotional and interesting aspect. Then there's Sirius Black. He was a beloved character who died in the original series. In time travel fanfictions, he could be saved or have a different story. And Voldemort is also an interesting character to focus on. We could see how his rise to power might be affected if Harry were to travel back in time and interfere.
It could also include some of the Hogwarts professors as main characters. For example, Professor McGonagall, who has always been like a mother figure to Harry. Her wisdom and guidance would be crucial for Harry as he comes home to Hogwarts or the wizarding world in general. And Dumbledore, even if he's passed away, his influence could still be felt strongly throughout the fanfiction.
Seamus Finnigan could be a great focus. He's often seen as just a side character, but in fanfiction, he could have his own moment. Maybe he discovers a new spell related to the Triwizard Tournament tasks that no one else knows about. He could use this spell to either help Harry or get himself into trouble while trying to prove himself.
Hermione is a great character to focus on. If reborn in the Harry Potter world, one could explore how she would be different if she had some extra knowledge or skills from her past life. Maybe she could be even more brilliant in magic and solve problems faster, or she could use her modern - day knowledge to make changes in the wizarding world like introducing new study methods.
