Superhero characters also make their way into time control fanfiction. Take Doctor Strange for example. His magical abilities already deal with otherworldly concepts, and time control can be added to his repertoire easily. He can use his powers to manipulate time to save the world or solve personal issues within the fanfiction.
Definitely Kakashi. He's already very intelligent and has a wide range of skills. Time control could be an addition to his arsenal, and he could use it in creative ways in battle or for teaching purposes. Also, Madara Uchiha could be a likely character. He was always seeking more power, and time control would be a very powerful ability for him to have in fanfiction.
Naruto himself is often very popular. Fans like to write about him exploring the concept of chaos control, perhaps using it to become an even more powerful ninja. His positive attitude and determination can be interesting to explore in the context of this new power.
Harry Potter himself is often involved. Writers might explore what would happen if he had more control over his powers from the start. Hermione Granger is also popular. She's known for her intelligence and control over her studies, so in fanfiction, she could be given even more control over magical knowledge or spells. Another one is Draco Malfoy. Fanfic writers might give him the ability to control his family's dark legacy and turn it into something positive, or he could be given control over some new form of magic.
Farah is also quite popular. Her relationship with the Prince, whether it's a romantic one or a strong friendship, is a common theme in fanfiction. Writers like to explore her character more, her backstory and her role in the overall story.
Well, in 'Stains of Time Fanfiction', the main character's best friend is often quite popular. Writers might use this character to add some comic relief or as a sounding board for the main character's thoughts and feelings. Also, any mysterious character in the original 'Stains of Time' tends to be popular in fanfiction. People are intrigued by their unknown backstories and motives, so fanfiction writers take the opportunity to create elaborate backstories for them. And then there are the characters with special abilities. In the fanfiction, these abilities can be enhanced or new ones can be added, which makes these characters very appealing to readers.
Sasuke is also quite popular. In time - based fanfictions, he might be involved in time - traveling scenarios where he is either trying to find a way to restore his clan in a different time or he's on a mission to change the past so that certain tragedies don't occur.
In some time - travel based superhero fanfiction, characters like Flash might be popular. His super - speed allows him to move through time in some versions, and so writers can explore different timelines and how his actions in the past or future affect the overall story.
There could be a mysterious elder Guardian who has a lot of hidden knowledge. In fanfictions, this character is often used to reveal secrets about the Guardians' past or to provide crucial advice during a crisis.
Sometimes, there are original characters created specifically for the fanfiction. These could be companions of the time traveler, like a local from a particular time period who joins him on his travels. They add new perspectives and relationships to the story.
I'm not entirely sure, but Naruto himself might be one of the main characters. Given his central role in the Naruto series, it's likely he'd be involved in any story related to time control in that universe.
