There could be a new character who has a quirk that is a combination of two very different powers. For example, the ability to turn into a liquid and also have telepathic powers while in that form.

And a villain with a quirk that can steal other people's quirks for a short period of time, which would create a lot of chaos and a big challenge for the heroes.
A character with a quirk that allows them to manipulate time on a small scale, like being able to slow down time for a few seconds in a small area. This could add a new dynamic to battles.

There could also be a villain whose quirk is to create illusions so real that they can even affect a person's sense of touch.
One potential new character could be a tech - savvy hero - in - training. Their quirk could be related to hacking into any technological device just by touching it.

She could use this to gather information or create barriers using overgrown plants. And a new villain with a quirk that makes him invisible to all types of detection, including quirks that sense danger or presence, would be a great addition.
A new character could be a family member of All Might. Maybe he has a long - lost nephew who discovers his relation to All Might and decides to follow in his footsteps, but has to overcome his own insecurities and lack of experience. Or a family member of Todoroki Shoto who has a quirk that combines both fire and ice in a unique way, and they come to help Todoroki understand and master his own dual - natured quirk better.
Stain could be considered as an anti - hero in fanfiction. His extreme views on heroes, while not entirely acceptable, could be delved into deeper.

A cool plot for My Hero Academia Heroes of Tomorrow fanfiction could be that there's a quirk - based disease that starts affecting heroes and students. The main characters then have to find a cure while still maintaining order in the hero society.

They would have to figure out how to get back while also dealing with this new and strange world.
A group of nomadic mice. They have different skills and traditions compared to the Redwall mice.
