Sure. Some fanfictions play with the idea of villain redemption. For instance, they might create a story where a well - known villain like Shigaraki has a change of heart and tries to use his powers for good. It's an interesting take as it goes against the normal villain - hero dynamic we see in the original series.
There are also fanfictions that focus on the relationships between the teachers. For example, a story could be about the friendship or rivalry between All Might and Aizawa. Since the main focus in the original is often on the students, this gives a different view of the world of My Hero Academia.
The 'Plant Symbiosis' quirk would be a great addition to a fanfiction. The individual with this quirk can form a symbiotic relationship with plants. They can communicate with plants, make them grow rapidly, and even use plants as an extension of their body for things like creating shields or lashing out at enemies. This quirk could bring a whole new element of nature to the story.
One idea could be that a kaiju suddenly appears in the My Hero Academia world and the heroes have to figure out a new way to combat it since their usual powers might not be as effective. For example, they might have to work together in a more strategic way than ever before, combining different quirks to create a new type of attack.
A cool idea for a Dark Shadow fanfiction could be a story where Dark Shadow gets separated from Tokoyami and has to find its way back. During this journey, it discovers things about itself and the world that it never knew before.
Perhaps a plot where Mineta enters a parallel dimension where the rules of his quirk are different. He has to adapt quickly to survive and find a way back home. This could lead to some interesting character development as he faces new challenges and has to rely on himself more. He might also make new friends or enemies in this parallel dimension.
Some fanfictions explore Dabi's family relationships in unique ways. For example, there are stories that focus on his relationship with his father, Endeavor, before he became Dabi. They might imagine how things could have been different if there had been more communication or understanding between them.
A popular 'My Hero Academia Best Gamer' fanfiction is 'Gaming in the Hero World'. This fanfic stands out because it not only incorporates the gamer theme but also delves deep into the relationships between the characters from the original series. The author does a great job of showing how the gamer abilities can be used to solve problems and form alliances. It also has some exciting plot twists that keep readers hooked from start to finish.
One cool quirk idea could be 'Shadow Mimicry'. The user can blend into any shadow and move freely within the shadow realm, also being able to mimic the actions of those whose shadows they are in. It gives a lot of stealth and surprise attack possibilities in a fanfiction.
A cool concept for My Hero Academia fanfiction is to have a time - travel plot. A character could go back in time and change a significant event in the My Hero Academia world. This could lead to a completely different storyline. Or you could write a story centered around a villain redemption arc. For instance, giving a more in - depth look at how a villain like Shigaraki could potentially be redeemed and how the heroes would react to that. Additionally, fanfiction about a tournament between different hero agencies could be really exciting.
Some popular My Hero Academia fanfictions include 'UA's Secret'. This one uncovers some dark secrets within UA High School that the students and teachers have to deal with. 'The New Symbol of Peace' is also great. It imagines a different character becoming the symbol of peace instead of All Might. Additionally, 'The Quirkless Hero' is a story that follows a quirkless character's journey to become a hero in a world dominated by those with superpowers, which is really inspiring.
There are many websites where you can find clean 'My Academia Hero' fanfiction, such as Archive of Our Own (AO3). On AO3, you can use the search filters to specifically look for stories that are rated 'General Audiences' or 'Teen and Up'. These will exclude any inappropriate content. Some popular stories might be those that focus on the friendship between the main characters, like Midoriya and Bakugo, and how their relationship develops over time.
