Hermione is also a prime candidate. Her inquisitive nature and her thirst for knowledge could lead her to accidentally stumble upon a time - traveling mechanism. Once in the past, she could use her intelligence to interact with historical figures and gain new insights into magic that she could bring back to the present.
There were a few manga novels about accidental transmigration that he could recommend. The first was " The Tokyo Avengers," a manga about delinquents, gangs, and brotherhood. It involved twelve years of conspiracy and consciousness transmigration. The manga had already announced that it would shoot a live-action movie this autumn. In addition," The Ship of Thesius " was a story about a person who returned to the time before he was born to save his village and family. It involved physical transmigration and multiple transmigration. In addition," Falling in Love with You a Hundred Times " was a story about a person who went back to the past countless times to save his lover. It belonged to the category of consciousness transmigration. For readers who liked anime, they could also try " The Witcher in Detective World ". This was a story about a wizard in the world of Conan. The protagonist solved the crime through the means of a wizard. These novels all provided plots of accidental transmigration into the anime world to satisfy the readers 'interest.
Ron and Hermione are also quite likely. They have that bickering - but - secretly - in - love dynamic. A spell could go wrong during one of their arguments and accidentally marry them. They'd have to deal with their own complex feelings and also the reactions of their friends and family, like how Mrs. Weasley would react to their sudden marriage.
One interesting plot could be that Harry accidentally travels back to the time when his parents were at Hogwarts. He gets to see them in their youth, and maybe even interacts with them in a way that doesn't disrupt the timeline too much. For example, he could help his father with a prank that was a big part of his father's Hogwarts story.
Time - turners are important in time travel in the Harry Potter universe, and so the characters associated with them could be involved. For example, Hermione, who was given a Time - Turner in the original story. But also, characters like Fred and George Weasley could be interesting inclusions. They are creative and mischievous, and they might come up with unique ways to use time travel to fix things. Maybe they could use their Weasley's Wizard Wheezes products in conjunction with time travel to make things right.
Batman himself is a likely candidate. Given his intelligence and determination, he might stumble upon a time - traveling device or technology while investigating some strange phenomenon. He would be driven by his need to protect Gotham, perhaps by preventing a future catastrophe that he has foreseen.
Ban could be another one. He has his own backstory related to the sins and his immortality. He might time travel to find a way to break free from his immortality curse or to go back and correct a mistake he made when he was under the influence of one of the sins, like greed when he stole something important in the past.
Star - Lord is a likely candidate. He's always been a bit of a risk - taker and his curiosity might lead him to experiment with time travel technology.
I think Fundy would be likely to time travel. He has a complex relationship with his family and the SMP. Time travel could be a means for him to understand his father better or change the way his family relationships developed. GeorgeNotFound could also be a candidate. He's often in the background but has a strong connection to Dream. Time travel might be his way of getting more involved in the SMP's events and helping Dream in a different way. Lastly, Niki could be a time traveler. She has been through a lot of changes on the SMP, and time travel could be her opportunity to go back and make the SMP a more inclusive and friendly place from the start, especially for those who have been marginalized.
It could be an older version of Orochimaru who has found a way to manipulate time as well. He might try to stop Naruto from changing the past in a way that would undo his own evil plans in the future.
Harry Potter himself is often a central character in these fanfictions. His journey through time to fix things or gain more knowledge is a common plot. Hermione is also popular as she's the brains and could potentially figure out the complex mechanics of time travel. Another popular character is Draco Malfoy. Writers like to explore his character in different scenarios, especially if time travel allows him to have a different relationship with the other characters.
