Often, you'll see young, rebellious protagonists. They're usually curious about the past or future and eager to break the rules of time travel. Another common character type is the wise old time traveler who acts as a guide.
There are the scientists or inventors who accidentally stumble upon time travel technology. They might be brilliant but also a bit naive about the consequences. Then there are the time agents whose job is to police the time continuum. They are often strong - willed and dedicated to protecting the timeline from any disruptions.
Well, it could include characters like Cassie Lang. Since she has shown an interest in following in her father's (Scott Lang) footsteps. She might be a key member of the next - generation Avengers in a time travel fanfiction. Another could be Kate Bishop. She has already proven herself as a skilled archer and fighter, and her abilities would be very useful in a time - travel adventure. And there's also Riri Williams, the young genius who could build amazing technology to help with the time travel and any problems they encounter in different time periods.
The children of the original charmed ones would be obvious main characters. They could inherit some of their parents' powers and personalities. For example, if Piper had a daughter, she might have some power over freezing time like her mother, but with her own unique twist.
Boruto is very likely to be one of the main characters. As the son of Naruto, he has a strong connection to the original story and would be a natural choice for a time - traveling adventure. Sarada, being Sasuke's daughter, would also be a key character. Her skills and her relationship with Boruto could drive the story forward in many ways.
Albus Potter is another obvious choice. As Harry Potter's son, he has big shoes to fill. In a time - travel story, he might travel back to understand his father better, or to fix a mistake that was made in the past that is now affecting the present wizarding world. He could also have some unique magical abilities passed down from his father that would come in handy during the time - travel adventures.
Perhaps the main characters could include a group of the next - gen mages who are all friends. There could be the child of Gajeel and Levy, with their combined intelligence and strength. Another could be a new character who is related to one of the less - prominent members of the original Fairy Tail but has a special power that makes them important in the time - travel adventure. They all come together, driven by different motives like curiosity, a desire to save the future, or to understand their past better.
Obviously, Bolt himself is a central character. His friends like Sarada, the daughter of Sasuke and Sakura, often appear. Naruto and Hinata also show up as Bolt's parents, guiding him or being a source of his inspiration or conflict.
Often, the children of the original Big Time Rush members are popular characters. For example, if Kendall had a son in the fanfiction, he might inherit his father's charm and singing talent and be a central character.
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.
Well, time travel being a form of punishment or redemption is an interesting idea. A character might be sent back in time to relive certain events and learn from their mistakes. Or perhaps time travel is not just about moving through time, but also about traveling between parallel universes which have different rules of time. This can open up a whole new set of adventures and challenges for the characters.
One idea could be that the next - generation Avengers accidentally travel back in time and interfere with a key event in the original Avengers' history. This causes a ripple effect that changes the present in unexpected ways. For example, they might prevent Tony Stark from creating the first Iron Man suit, leading to a world where technology has developed differently. They then have to figure out how to fix the timeline while also dealing with the different threats in this new reality.
