The main characters are likely to be Neville, Luna, and Ginny as they are known as the Silver Trio in the Harry Potter universe.
Since it's a fanfic, it might take a different spin on the characters. It could show the Silver Trio facing some unique threats that were not part of the original series. It might also explore their friendships in more depth, like how they support each other through difficult times. There could be a love triangle among them or some other complex relationship dynamics that the author has created to make the story more engaging and different from the canonical Harry Potter tales.
The characters in the 'dark trio' in the fanfiction are likely to be those who have a propensity for the dark arts or have some sort of malicious intent. It could be that the author takes minor characters from the original series and gives them more prominent roles within this dark context. For example, Crabbe and Goyle could be developed further into more menacing characters, or perhaps some of the Death Eaters that were not as well - explored in the original books could be part of this trio.
It really depends on the specific fanfic. In some, it could be an original character created by the fanfic author who has the silver tongue ability. In others, it might be a well - known character like Hermione, but with a new twist where she suddenly develops a silver tongue and uses it in her adventures.
Neville Longbottom is a wonderful character to add. He has grown so much throughout the series and can be a great support to the trio. Dumbledore, even if in a ghost - like or memory form, can offer his great wisdom. Also, Draco Malfoy can be included in an interesting way. Maybe in fanfiction, he has a change of heart and teams up with the trio against a greater evil.
Obviously, Harry is a main character. His friends like Hermione and Ron might also be important as they could help him understand and control his silver magic. There could also be a new character, perhaps a wise old wizard who has some knowledge about this rare type of magic and guides Harry in his journey with it.
Fred and George Weasley could be really fun to include. Their prank - loving nature and inventiveness could add some humor and unexpected solutions to the problems the Golden Trio might face in fanfiction. Additionally, Remus Lupin would be a great fit. His knowledge of dark creatures and his kind heart could make him a valuable ally for the trio.
One common theme is loyalty. The death trio has complex relationships, and loyalty within the group and towards other characters is often explored. Another theme is power. How they gain, use, or are corrupted by power is a frequent topic.
I don't know for sure as I haven't read this particular fanfic. But it could have the main character be an original creation with the 'lionheart' trait, or it might center around a well - known Harry Potter character like Harry himself with some new 'lionheart' - inspired story arc.
Well, in many Harry Potter fanfics, even those named 'the change', the main characters often include Harry, Hermione, and Ron. However, depending on what the 'change' is about, new characters could be introduced or existing minor characters could be promoted to main character status. For example, if the change is about the Slytherin house becoming more inclusive, we might see Draco Malfoy taking on a more central role in the story, along with the usual trio.
It could be a Muggle - born protega. This character would face unique challenges as they try to protect the wizarding world while also dealing with their own identity issues. They might have friends among the Hogwarts students, and together they form a group to counter a new evil force that targets both Muggles and wizards.
