Who are the most likely characters to have important roles in 'Harry Potter reborn as James Potter fanfiction'?

Harry Potter himself, of course. He has always been at the center of things in the wizarding world. His actions and decisions would likely have a great impact on any change that occurs.

Well, Lucius Malfoy could have a different role. If Harry redoes his life, he could try to turn Lucius against Voldemort by using his knowledge of Lucius's family and situation. This would change the power dynamics within the Death Eaters. Bellatrix Lestrange could also be affected. If Harry were to act differently towards her, perhaps by trying to capture her earlier or using her as a source of information, her role in Voldemort's plans would be altered. And of course, Ginny. Harry could start his relationship with Ginny in a more mature and different way, which would change their dynamic and her role in the overall story.

One character that would likely have a different role is Sirius Black. In an alternate universe, he might not have been wrongly imprisoned, and he could be a full - time mentor to Harry. Luna Lovegood could be a more powerful and influential figure in the wizarding world. And Voldemort himself could be a reformed wizard, which would turn the whole story upside down.

Obviously, Harry Potter himself would be one of the main characters. He's the central figure in the Harry Potter universe. Hermione and Ron would also likely be important, as they are Harry's closest friends. From 'F is for Family', the father figure, Frank, could be a main character as well, bringing his own brand of family values into the story.

Ron Weasley also plays a vital role. He is Harry's best friend, providing loyalty, humor, and in some cases, key insights. His family, the Weasleys, also add a lot to the story, representing the more down - to - earth and warm - hearted side of the wizarding community.

Voldemort is the main antagonist. His quest for power, his pure - blood ideology and his actions drive the entire plot of the series. He is the most feared wizard in the wizarding world and Harry's ultimate enemy. Characters like Hagrid also play important roles. Hagrid introduces Harry to the wizarding world, and his love for magical creatures and his big heart make him a beloved character in the series.

Harry Potter himself is crucial as he is the main protagonist. He is the Boy Who Lived, the one prophesied to defeat Voldemort. His journey from an orphan boy to a powerful wizard is at the heart of the story. Hermione Granger is also extremely important. She is highly intelligent and her knowledge of magic and quick thinking often save Harry and Ron. For example, in many dangerous situations in the library or during battles, her spells and research are vital.

Hermione is a very likely candidate. With her intelligence, she could easily start a business. For example, she might open a library - like establishment but with rare and restricted magical books that she has managed to collect through her research. She could charge a membership fee for witches and wizards to access these valuable resources.

Neville could be another character. He might look up to Harry even more in his dragon form, seeing him as an even more powerful protector. Hagrid would be excited to have a dragon - Harry around. He could help Harry understand his new dragon nature. And some of the Slytherins, like Draco, might be jealous or scared of Harry's new form.

Obviously, Petunia in the form of reborn Harry would be the main character. Vernon and Dudley Dursley would also be important as they are part of the family. And we can't forget about the wizarding world characters like Dumbledore. He would surely notice some changes in Petunia and might start to investigate. Also, there's a good chance that Hagrid would be involved in some way, perhaps bringing some news or event that would set the story in motion for Petunia!Harry.
