Summary
Like most things, Izuku didn’t particularly want to start his career as a vigilante. In the same way he didn’t want to go to school every day to quirkist teachers, or how he didn’t want to be the victim of bullying and assault daily, oh, and he especially didn’t want his mom to run off and abandon him.
But, there are laws and there are legalities, and in this day and age in Japan, his quirk status leaves more wiggle room than should be allowed.
vigilantism had a similar situation. The laws stating something along the lines of: ‘a person, or persons, who is caught practicing unauthorized quirk usage for heroic acts, disregarding self-defense, will be prosecuted and may be fined up to-‘. Yeah, yeah, blah blah, the important part there is ‘quirk usage’, and fortunately (or unfortunately) that didn’t apply to Izuku.
.
Or, an author who’s tired of unrealistic fics where a teenage vigilante is trying to keep too many secrets, and decided to write one for themselves.

Summary
Katsuki was confident that he remembered the exact moment knew he was trans, one day he just woke up and knew he wasn’t a girl. It wasn’t anything long and drawn out over a couple of months, it just happened.
It was like any other morning, truthfully, except as he passed by his bedroom mirror on his way down to the kitchen, he froze. Only for a moment, just a split second to analyze his uniform and decide he absolutely hated it.
.
OR! The idea I had that started my friend group and led to the found family trope irl <3

Summary
Izuku Midoriya was well aware he had some not-great habits. If you asked his teachers, they’d probably tell you that he had a habit of getting into trouble with villains and breaking his bones. If you asked his friends some of them might bring up his mumbling, or maybe his inability to accept compliments. If you asked Shinso he’d bring up Izuku’s poor sleeping habits.
But if you asked Izuku himself about his bad habits? Well, he certainly had worse ones than that.

Summary
(This fic is the original version. Check out part 1 of the series for the new version.) Izuku Midoriya, the cinnamon roll of class 1A. To the class, he was the sweet, shy boy who blushed at any passing compliment. To Shōta Aizawa, he was the number one problem child. As much as he tried to deny it, Izuku was Shōta's problem child. What happens when a grumpy teacher is thrust into a new role as his problem child asks for his help? Chaos. That's what his new found son brought to his life. Pure, unfiltered chaos, but he wouldn't change it for the world as Shōta never thought that he would have a son; any child that happened upon him was usually either afraid of him or annoyed him to no end but not Izuku Midoriya, his number one problem child is now his son.
