Sherlock Holmes in a fanfiction could change his strategy. Instead of being so aloof and solitary in his investigations, he could start collaborating more with the police force. He might share his deductions earlier and work with the constables to gather evidence in a more coordinated way, which could lead to quicker solutions to the mysteries.
In a Harry Potter fanfiction, Hermione could change her study strategy. Instead of always being so focused on textbooks and traditional magic learning, she could start exploring more of the hidden and forgotten magic in Hogwarts. This would involve her seeking out old spells from the restricted section, talking to ghosts about ancient magic, and using this new knowledge to help Harry in the fight against Voldemort.
One possible plot could be a character in a fantasy world who has always been a lone wolf suddenly decides to join a guild. This change in strategy forces them to learn to work with others, deal with different personalities, and face new challenges as part of a team instead of on their own.
A young alien with a special gift for sensing the changes could be a main character. This alien could be from a species that has been living in harmony with the universe for a long time but now has to face the new, unexpected changes. Another option could be a rogue adventurer who has been traveling through different parts of the universe and has seen a lot of the changes first - hand. They could be a bit of a loner but end up having to team up with others to deal with the overarching issues of the changing universe.
A lost princess could be the main character. She was supposed to marry a cruel prince as part of her pre - arranged destiny, but she rebels. She disguises herself, travels the land, and meets different people who help her change her destiny from being a trapped royal to a strong and independent leader of her people.
It could be a minor character from the original story. For instance, a servant who has always been in the background but suddenly gets thrust into the center of events and has to change their own destiny as well as those around them.
The protagonist from the original work can be a main character. For instance, if it's a fanfiction based on a superhero story, the superhero could be the main character who changes their tactics. Maybe they stop relying on their superpowers all the time and start using their intelligence more. Another potential main character could be a sidekick who steps up and changes their tactics to fill in when the hero is incapacitated. For example, they might start using some of the hero's gadgets in a different way than the hero does.
It's hard to say without actually reading the fanfiction. It could be the underdog character who is seeking a new start in life. Maybe it's a young adventurer who has been down on their luck and this chance to change fate is what sets them on a new path.
Most likely, the main characters would include Bilbo Baggins. Since it's a Hobbit - centered fanfiction, he's bound to play a significant role. He might be the one whose fate is changing or the catalyst for the change in others' fates.
