Fred and George Weasley! Imagine them traveling back in time. They'd surely come up with all sorts of pranks using the knowledge of the future and the magic of the past. They could introduce modern - day joke products to the wizarding world of the past and create chaos. And Sirius Black, if he traveled back in time, could use his charm and mischievousness to get into all kinds of adventures. He might even try to change some events related to his own family's dark past in a humorous way.
Neville Longbottom could have an interesting role. If he time - travels, his new - found confidence from the later years could be a contrast to his more timid self in the past. He could use his knowledge of plants from the future to amaze or terrify the wizards in the past. Also, Professor McGonagall. If Harry or someone travels back in time and has to deal with a young McGonagall, her strict yet fair nature could lead to some really comical situations, especially if they break the rules in front of her.
Hermione would be a great character in a time travel scenario. Her vast knowledge of magic and history could either be a huge help or cause some really funny mix - ups. For example, she might try to correct historical inaccuracies she finds during her time travels, but end up changing things in unexpected ways. Dumbledore is another character. If Harry were to travel back in time and meet a young Dumbledore, Dumbledore's wisdom and his own mysterious past could lead to some really interesting and humorous interactions.
Goku would be really interesting. His naivete in a time - travel situation could lead to all sorts of unexpected events. He might not fully understand the implications of changing the past and end up doing things just because they seem fun at the moment. Sanzo is also a great choice. His no - nonsense attitude in a different time period could create a lot of conflict, especially if he has to deal with the different cultural and social norms of the past. Another interesting character is Hakkai. His intelligence and ability to adapt would make for some really engaging time - travel stories as he tries to figure out how to use his skills in a new and unfamiliar time.
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.
A scenario could be that Lily travels back to her Hogwarts days and tries to change the way she treated Snape. This could have a huge impact on Snape's future actions and loyalties. Maybe she could have been more understanding of his difficult situation, which might have led to him not being so easily swayed by the Dark Arts.
Hermione Granger could be one. Her intelligence and thirst for knowledge might make her interested in a time - traveling character. Ginny Weasley is also a likely candidate. She's brave and has her own charm. And Luna Lovegood, with her unique view of the world, would probably be drawn to the mystery of time travel. Another potential character could be Pansy Parkinson. Her strong - willed nature might lead her to be part of the harem in a different way compared to the others.
Daniel LaRusso would also be great. Imagine him traveling back to the time when Mr. Miyagi was teaching him as a young boy. He could relive those moments and maybe learn something new that he can apply to his current situation in the series. He might also use his knowledge of the future to prevent some bad things from happening to his family.
One idea could be Harry traveling back to the time of the founders of Hogwarts. He could interact with Godric Gryffindor, learn from him, and maybe even influence the way the houses are initially set up. Another plot could involve Harry going back to the time when Voldemort was a student at Hogwarts. He could try to understand what made Voldemort turn so evil and perhaps prevent some of the early events that led to his dark path.
For Logan in a time - travel fanfiction, keep his core traits intact. His gruffness, loyalty, and his inner struggle with his past should still be there. But add new layers based on the time - travel experience. For example, if he travels to the past, he might be more cautious as he knows the future consequences.
Obviously, Harry Potter himself would be central. But also, Dumbledore could play a big role. Maybe Harry travels back in time and meets a young Dumbledore, and they work together to solve some mystery or change an event that Dumbledore later regretted. Hermione would also be a key character. Her intelligence and love for research could be very useful in exploring the implications of time travel and immortality in the wizarding world.
Harry Potter, of course. He has the most potential for character development in time travel scenarios. He can interact with his parents, for example, which would be a very emotional and interesting aspect. Then there's Sirius Black. He was a beloved character who died in the original series. In time travel fanfictions, he could be saved or have a different story. And Voldemort is also an interesting character to focus on. We could see how his rise to power might be affected if Harry were to travel back in time and interfere.
Voldemort could still be the antagonist even if they travel back in time. If they go back to a time when he was already active, like when he was at Hogwarts as Tom Riddle, he could oppose their attempts to change the future or disrupt his plans. He might sense their presence and try to eliminate them.
