In many BNHA fanfictions where Izuku meets All Might early, it often changes the entire trajectory of Izuku's development. For example, he might gain confidence much sooner. Early meetings can also lead to a more in - depth mentorship that might deviate from the original storyline. This could result in Izuku getting special training earlier and potentially unlocking his Quirk in a different way.
One consequence could be a faster growth in Izuku's power. With All Might's early guidance, Izuku may master his Quirk more quickly. Another is that his relationships with other characters might change. For example, Bakugo could become more jealous or, on the contrary, might be inspired to work harder.
Villains who want to use her as a bargaining chip against All Might could be main antagonists. They might think that by capturing her, they can force All Might to do their bidding.
One interesting plotline could be her struggle to live up to her father's legacy. Since All Might is such a great hero, she might constantly feel the pressure to be as good as him. Another could be her dealing with the attention she gets because of her relation to All Might, whether it's positive or negative attention from the public or other heroes.
A character who could be the stalker is Gentle Criminal. He has that sort of flamboyant and devious nature that could lead him to stalk All Might out of some strange admiration or to prove himself as a worthy 'opponent'.
One idea could be that the stalker is a villain who wants to expose All Might's secrets to undermine his heroic image. Another could be a misguided fan who thinks they are protecting All Might but their actions are actually causing trouble. Maybe the stalker has some sort of connection to All Might's past that they are trying to uncover.
I think Dwayne Johnson would be a great choice to play All Might. He has the physique and the charisma that would fit the role perfectly. His presence alone can command a room, just like All Might in the BNHA series.
The Bnha universe's reaction would be mixed. Those who are into complex stories, like Todoroki, might study the relationships in Hamilton fanfiction. But others, like Mineta, might not be interested at all because it doesn't have much to do with his usual interests. Overall, it would depend on the individual characters' personalities and interests.
Mineta could react with a mixture of embarrassment and defiance. He's a proud character in his own way. So when All Might yells at him, he might try to put on a brave face and argue back a little. But deep down, he knows he's in the wrong. Eventually, he'll break down and start crying, realizing that he has disappointed not only All Might but also his classmates who are all striving to be heroes.
The world would be in shock. The media would be filled with reports of his death. Civilians who had always seen him as a symbol of safety would feel vulnerable. There would be mass mourning in the cities he had protected.
