In some izuku time travel fanfiction, he travels to the future instead. There, he discovers how his actions in the present have affected the world. It could be a dystopian future where his absence led to chaos, and he has to find a way to go back and fix things.
There are also izuku time travel fanfictions where he travels to different points in time within the My Hero Academia universe randomly. Each time he arrives at a new time, he has to adapt quickly and figure out how to use his powers in that era without causing too much disruption.
In a particular Izuku Midoriya time travel fanfiction, he travels to a time when the villains were just starting to form their groups. He infiltrates their ranks secretly, using his knowledge of their future plans. By doing so, he manages to disrupt their plans from the inside out, saving many lives in the process and changing the whole hero - villain dynamic in the story.
In some izuku time skip fanfiction, Izuku could have developed his own unique fighting style during the time skip. For example, he combines his original combat training with the various quirks of One For All in unexpected ways. This makes him a more formidable hero, and his battles are not just about brute strength but also about strategic use of his abilities.
In some izuku time travel fanfics, he travels to a different point in time within the MHA world, like a time when quirks were first emerging. Here, he has the opportunity to shape the understanding and use of quirks from the very beginning. He might introduce new ways of thinking about quirks or help create a more inclusive society for quirk - users much earlier than in the original timeline.
One interesting 'izuku is a dragon' fanfiction could be about Izuku using his dragon powers to protect his friends in new and unexpected ways. For example, he might be able to breathe fire to fend off villains, or use his dragon wings to quickly reach those in need.
All Might often appears. Since he was Izuku's mentor, in time travel scenarios, he might be the one Izuku turns to for advice or assistance. Another common character is Bakugo. Their complex relationship can be explored further in time travel stories, like if Izuku goes back in time, he might try to change how Bakugo treated him in the past.
One interesting plotline could be Izuku using his time - control ability to go back in time and prevent a major villain attack before it even starts. This would show his heroic nature and how he can change the course of events for the better.
One interesting plot could be Izuku going back in time and using his future knowledge to prevent certain tragedies. For example, he might stop the initial injury that All Might received, which could change the whole course of the story. Another plot could be him going back to his own childhood and being able to train better and earlier, thus becoming an even stronger hero. He could also use his knowledge of future villains to stop them before they become a major threat.
One idea could be that Izuku's time quirk allows him to reverse time for a short period during battles. So he can correct his mistakes and outwit his opponents. For example, if he made a wrong move in a fight against a villain, he could reverse a few seconds and choose a better strategy.
One interesting 'izuku gets expelled' fanfiction could be where he gets expelled due to false accusations of cheating. In this story, villains frame him to get rid of a potential threat. Another might be a story where his quirk goes out of control during a test and the school, in a panic, expels him. There could also be a fanfic where a jealous classmate sets him up to look bad and get expelled.
One interesting story could be where Izuku gains some of Captain Marvel's powers and has to learn to control them in a world full of villains. He might struggle at first, like he did with One For All, but gradually master it.
