Part 1
in this Izuku was deemed quirkless and so his mum took him to visit his auntie in morio, at five years old Izuku got struck by the stand arrow, giving him a stand, izuku's stand is not the same as other stories about it though, going by the struggle, a humanoid stand, that at first had the power, to force someone to foresee the worst case outcomes, for its user or those it hits.
And Izuku found out about his new abilities, only two months after, in a bizarre incident, that bakugou didn't see because he was sick, a random villain attacked, this villain had some kind of resentment of kids, so when Izuku stood up to this villain, and didn't seem scared, the villain decided to attack.
In the very moment Izuku used the struggle, but found out it could use any abilities seen, including the time stop jotaro had, the villains quirk had already hit the staff, after Izuku beat the villain in seemingly no time, all the staff present seemed to turn into kids, and so did their mental state, their memories changed and their quirks did too.
One of the girls got the unlucky hand, getting a quirk that had negative effects pretty much, her quirk was dubbed lust, basics of it makes guys go, into sudden uncontrollable lust, if the user gets wet in any way, be it water from a horrible prank, to her just being rather turned on.
Anyway, Izuku also is still a fanboy, but now he also has a motive to watch, if Izuku could learn about a heroes quirk, he could add it to his arsenal of abilities, so Izuku saw the struggle as a copy stand, a copy stand has the ability to copy powers it sees, from healing abilities to something much more sinister, on top of quirks and hero notes, Izuku pieced together ways to improve and counteract weaknesses that come with the quirks.
During the first year of middle school, izuku's the struggle had quite the Arsenal, he even worked out some tricks he could use.
After izuku had found out about the struggle, the stand showed it's unique personality, of being overprotective, but not quick to anger, in fact Izuku and the struggle, aren't easy to anger and when they do get angry, it's not a case of their less rational, they become more analytical and cautious, of what's going on.
Now everyone doesn't try their luck, with attacking Izuku.
And thanks to his stand, everyone who bullied him other than bakugou, decided to drop the whole thing, and Izuku managed to copy some useful abilities, in the class, sadly there were practically three, an argumentation quirk, that allows the user, to manipulate parts of their body, however they like, a quirk that can give a sort of adrenaline effect, to its user, making them numb to pain and unfazed by most hits, and a capsulising quirk, the argumentation quirk was called change, adrenaline quirk was called rush and the capsule quirk was contain.
Now Izuku explained things to his class, when they asked about his quirk, avoiding showing it and lying about some things, or tell half-truths.
Izuku told them that his quirk, manifested a ghostlike avatar, that could use the power, to project the absolute worst case scenario, and after witnessing it, his power gained the ability to stop time, other than that, Izuku told them, that it has a set range, where his abilities can go alongside other things.
Izuku pulled out a notebook and a few pencils, drew a circle, then started to work from there, until he had completed what he was working on.
