Who could be the main character in a 'Harry Potter Dark Time Travel Fanfic'?

A descendant of one of the original founders of Hogwarts. They might have some special connection or mission related to the school and the wider wizarding world. They would travel around to uncover secrets about their family's past and the history of the magical places.

Scorpius Malfoy is another likely main character. His family's history and his own inquisitive nature would make him an interesting addition. He might be the one who discovers the time - travel mechanism. His relationship with Albus Potter could also be explored further as they embark on this time - traveling adventure together, and his views on his family's past actions could change during the journey.

Another possible antagonist could be some of the Hogwarts faculty who were either secretly supporting Voldemort or were too cowardly to oppose him. In a time - travel revenge fanfic, Harry might uncover their true natures and take revenge on them for not doing more to protect the students and the wizarding world from Voldemort's rise.

Harry Potter himself could be the main character. Imagine him stumbling upon a dark keyblade and having to grapple with its power. He would have to decide whether to use it to fight Voldemort or risk being corrupted by its dark influence.

Lily Luna Potter might also be a main character. She has a strong personality and her own set of skills. Her presence in the time - travel plot could bring a different perspective, especially when it comes to interacting with the female characters from the past.

It could be a new character, like a young Auror who has been assigned as an inspector. He would be fresh out of training and eager to prove himself at Hogwarts. He might be a bit naive at first but quickly learns the ropes and uncovers some interesting things about the school.

It could be a young witch who is just starting to explore her magical abilities outside of Hogwarts. She takes on a babysitting job to earn some extra money and ends up having all sorts of magical adventures with the kids she babysits.

A new character could be the main character. For instance, a Saiyan who has been transported to the Harry Potter universe. This character would have to navigate the strange new world of magic while also dealing with their own Saiyan instincts and powers.

It might also be a descendant of one of the well - known characters from the Harry Potter series. For example, a grandchild of Sirius Black who inherits his rebellious spirit and uses it to fight against the new dark forces as the 'darkslayer'.

A new student at Hogwarts could be the main character. They might be a bit of an outcast and find solace in the graveyard. There, they stumble upon a mystery that no one else has noticed before, and it becomes their mission to solve it. This would be a great way to introduce a fresh perspective to the Harry Potter fanfic world.
