In my opinion, Remus Lupin can be an interesting character in Harry and Lily Potter fanfiction. He could play a role in helping Harry understand his mother better, perhaps by sharing stories about their time at Hogwarts. Also, Bellatrix Lestrange could be an interesting addition. Imagine her being involved in a plot that somehow involves Lily and Harry, adding a new level of danger and conflict. And don't forget Dumbledore. His wisdom and guidance could be portrayed in new ways in relation to Harry and Lily.
Well, obviously Harry and Lily themselves are very interesting. Harry because we get to see a different side of him when interacting with his mother. Lily is interesting as we can learn more about her personality and her life before Harry was born. Then there's James Potter. In fanfiction, we might see more of his relationship with Lily and how he influenced Harry even from the afterlife. And Snape, his complex relationship with Lily can be further explored in the context of these fanfictions.
One interesting plotline is when Lily is given the chance to change the future. In some fanfictions, she has the power to go back in time and make different choices, like whether to marry James or not. Another is when she discovers hidden magic within herself that no one else knew about. This often leads to her having to face new challenges and enemies.
James Potter often makes an appearance. Since he was Lily's husband, his relationship with both Harry and Lily is explored in different ways. For example, in some fanfictions, Harry gets to see a side of his father through Lily's memories that he didn't know before.
One of the most interesting characters can be the shifter protagonist themselves. They bring a new dynamic to the story. For example, a shifter who can turn into a phoenix might have the power of rebirth and be a symbol of hope. Another interesting character could be a wizard who befriends the shifter and helps them navigate the wizarding world, like a young Hermione - type character using her intelligence to understand the shifters' unique situation.
In many 'harry potter ma fanfiction', Luna Lovegood remains a very interesting character. Her unique perspective and rather odd yet endearing personality make her a great focus. She often gets involved in adventures that showcase her wisdom and bravery in ways the original series only hinted at. Another interesting one is Sirius Black. Fanfiction can explore more of his life before Azkaban and his relationships with other characters like James Potter more deeply. And of course, the Marauders as a group are always fascinating in fanfiction, with their pranks and close - knit friendship being expanded upon.
Snape is an extremely interesting secondary character for fanfiction. His double - agent role and his complex feelings towards Lily Potter can be explored from different angles. There are fanfictions that focus on his early years at Hogwarts, his relationship with the Marauders, and how all of that shaped him into the man he became. Another character is Cho Chang. Her relationship with Harry can be re - examined and extended in fanfiction, and she can also be given more depth and backstory outside of just her romantic connection to Harry.
There's a character in some fanfictions called Lyra, a half - veela who has the power to control emotions. She becomes Harry's love interest and her powers often come in handy during battles. Another interesting one is Orion, a powerful wizard who was once a student at Hogwarts but was banished for trying to expose a dark secret within the school. He returns to help Harry in his fight against Voldemort.
Definitely Harry Potter himself. He's always at the center of the action and in fanfiction, he can have new and unexpected powers. Also, Luna Lovegood can be really interesting as she often has unique insights and can use her strange but effective magic in battles.
Luna Lovegood might be a great character in this fanfiction. Her own family situation is a bit different and she has a very open - minded view of the world. She could be a source of comfort or inspiration for characters dealing with family trouble, and her quirkiness could add a new dimension to the story.
Harry Potter himself can be very interesting in these fanfictions. Authors might explore his true power in ways that J.K. Rowling didn't fully cover. For example, they could give him an ability to communicate with all magical creatures without the need for spells. Hermione is also a great character in fanfiction. She could be shown as having a hidden power related to ancient magic that she discovers through her research. Ron might also have a more significant role, like having a power to boost the morale of those around him in a magical way during battles.
Well, Sirius Black can be quite interesting in 'Harry Potter goes dark fanfiction'. If Harry goes dark, Sirius, who has always been a protector figure, might have to make some very difficult choices. He could either try to save Harry from the darkness or be forced to oppose him. Dumbledore is another character that stands out. His wisdom and manipulations would be under a new light in a dark fanfiction. And the Weasley family, especially Ron. His friendship with Harry would be severely tested if Harry goes dark, and his own character development could take some very different paths.
