What are some changes to the narrative you'd make to make it satisfying in your fic.
I just watched an hour long video essay on the entire series and the narratives. And they're actually pretty good a lot of the time. Deku and Shiggy and the 'reaching out', All for One being the man dying to go back to his prime where everything he took was, vs All Might, the dying man making his new prime thanks to everyone he taught, etc.
But things change in fanfiction. One example I could make is Stain. He's Iida's big bad, the one moment where he strays from rules and regulations, but outside of Tensei being crippled, not a lot of things to contrast. What I'd do is maybe change it with Ochako. Her storyline with her wanting to support her parents never goes anywhere, so that could be an interesting angle.
Other could be Toga. I'm going to be the first to admit I'm a Toga Hater, but that's because of her attitude, her character still has some good things about it. So maybe instead of being Ochako's villain, she could replace Muscular and be one of Izuku's recurring villains. Everyone knows about the part of the quirk nerd and all, but what I'm imagining is that if Toga was quirkless, her life would have been MUCH better, and since OFA was revealed eventually, seeing someone fight so much to be 'normal', which is opposite of Toga's ideology could be interesting.
Or maybe smaller narratives, maybe the Culture Festival, instead of being about Jirou and her being shy about what makes her special, could be about Iida and his inability to be chill, needing to learn to relax appropriately.
