It could be Deku's son or daughter. They would inherit some of his amazing quirk, but also face the pressure of living up to their father's legacy. They would have to carve their own path in the hero world.
One possible plotline could be about the next generation of heroes. Maybe the children of the current heroes are starting their own hero journey at UA High. They might face new villains with even more complex quirks.
One interesting plotline could be Deku facing a new, extremely powerful villain that challenges his understanding of heroism. Maybe this villain has a quirk that can nullify all other quirks, forcing Deku to rely on his wits and physical training rather than just his One For All power.
Another possibility is that the fanfiction explores the powers of the characters in a new light. Since they are in a different time period, they might have to use their quirks in unexpected ways. Maybe some quirks are more or less effective in the past compared to the present, and this creates new challenges and strategies for the heroes as they try to change the future.
There might be a new character who is a tech - genius and uses advanced gadgets to fight crime. They don't have a traditional quirk but instead rely on their intelligence and engineering skills. This would be a fresh take on the types of characters in the story. Also, a character who has the ability to communicate with animals and enlist their help in battles could be really interesting.
Well, in some fanfictions, there might be a plot twist where the future that is being watched is actually an alternate and false future created by a powerful villain. This would completely change the characters' understanding of what they need to do to prevent it. Also, perhaps a character who has been in the background suddenly reveals a powerful and unexpected quirk that saves the day.
Uraraka is also common. Her friendship with Deku, and perhaps a budding romance in some fanfictions, can add an interesting dynamic. She could be involved in missions with Deku or be there to support him during difficult times.
Definitely Izuku Midoriya. He's the main protagonist in the original series, so he would probably play a crucial role in any 'Days of Future Past' type of story. He could be the one leading the charge to change the future.
