A cool fanfiction idea could be Tomura getting transported to another universe where there are no quirks. He'd have to adapt to a completely different world without his powers. It would show his character in a new light as he has to rely on his wits and other skills. This could also lead to him having a different perspective on life and his actions in his own world.
One idea could be exploring Tomura's backstory in more detail. Maybe show his life before he became a villain, his family situation, and what led him to the path of destruction. Another could be a 'what if' scenario, like what if Tomura was redeemed and joined the heroes. He could use his knowledge of the villains to help the heroes take down other threats.
One idea could be exploring Tomura's past in more detail. Maybe show his childhood before he became a villain, how he was influenced by All For One. Another could be a story where Tomura tries to redeem himself, which would be a huge twist from his normal villain role.
Dabi could be a great character to pair with Tomura. They are both villains and their powers and personalities could create some interesting interactions. Maybe they could team up for a particularly difficult mission or have a power struggle within the League of Villains.
It could completely change the dynamics of the story. Maybe Deku would have a different perspective on villains and their motives.
Well, you could focus on the relationships between the characters. Write a fanfiction about a friendship that forms between two characters who initially didn't like each other. For instance, Bakugo and Midoriya could have a different kind of relationship where they become more like brothers through a series of events that force them to rely on each other. Or you could write about the teachers' lives outside of teaching at the academy. What do they do in their free time? What kind of challenges do they face that the students don't know about? You could also write a story where a new villain emerges with a quirk that is completely unexpected and throws the whole hero society into chaos.
A fanfiction focusing on the family lives of the characters can be interesting. Like, how does Bakugo's family interact when he's not around? Or what was Midoriya's father really like? By delving into these aspects, you can add more depth to the existing characters and show a different side of them that the original story might not have fully explored.
Overall, Tomura's mask in the My Hero Academia manga is designed to make him look more menacing and intimidating. It often plays a role in emphasizing his evil presence and sets him apart from other characters. The mask's details and style contribute to the overall atmosphere of the story.
How about a fanfiction where the villains and heroes have to team up? There could be a greater threat, like an alien invasion or a powerful quirk - user who is out to destroy the entire world. The heroes and villains realize that they can't defeat this threat alone, so they put aside their differences. This would lead to some really interesting character interactions, like Bakugo having to work with Shigaraki and both of them learning to respect each other's skills despite their opposing natures.
In 'hero academia sludge fanfiction', you might consider a story where the sludge is actually a misunderstood entity. It was once a normal substance but got corrupted by some evil force. A hero could try to purify the sludge instead of just fighting it. They might have to go on a quest to find the source of the corruption and in the process, learn more about the true nature of the sludge.
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.
A cool fanfiction concept could be to have a character lose their quirk and then have to find a new way to be a hero. This would show their determination and resourcefulness. Or, you could write about a new villain who has a quirk that specifically targets the heroes' weaknesses, and how the heroes would have to work together to overcome this threat.
