Summary
“There’s really not much that can be done about it except wait for the quirk to wear off.”
Taishirou stares down at the two children standing before him instead of the woman talking to him. One smiles up at him, arms raised as if asking to be picked up, while the other is biting nervously on his thumb and looking as if he’s about to start crying.
“And how long will that be?” Taishirou picks up the younger of the duo, and grins wide at the cheerful giggle it earns him.

He didn’t know what he expected when he rounded the corner, cat treats in hand and ready to tell them they were leaving, but it was not a very uncomfortable Todoroki stood with a sobbing green haired toddler at his feet, of whom was wearing a grey shirt like a nightgown.
No, wait, that was a very familiar green haired toddler.
That was Midoriya?!
“It wasn’t me.”
“Yeah, I gathered you didn’t turn Midoriya into a toddler, Todoroki, what happened?”

Summary
It should have been an easy mission. The League had gone to meet up with some possible new recruits, and while Hawks couldn't accompany them due to a secret assignment ordered by the Commission, he had left them all with some of his feathers with the note to destroy them in an emergency. They were still wary of Hawks, understandably not trusting the Number 2 Hero, but still accepted the gesture. Unbeknownst to them, Hawks had also left some feathers following them, settled in a warehouse nearby in case they needed it.
That's not to say he ever expected anything to go south drastically enough to call for him.
------
Or, the League of Villains ask call Hawks for help when they're cornered. He goes to their rescue and gets hit with a quirk, becoming de-aged in the process.

“Is that why the old hag mentioned accomodations?”
Izuku choked on his spit, drawing an unfortunate parallel between Yagi and Kacchan. Well… At least this showed there was some hope for his childhood friend still…
“It’s mostly because of the paparazzi, really.”
Yagi raised the phone pointedly. “I don’t exist-”
“Not under your civilian name,” Izuku agreed.

Summary
Young Izuku nods. He’s still pale, with a careful blankness to his face, and his shoulders tremble slightly when he moves. In a small, sure voice, he says, “I’ve thought about what you told me, and what I’ve seen. And there’s only one explanation: I’m dead.”
“Ah,” says Mirio.
Izuku rubs his forehead with the heel of his hand. “We should probably just call Mr. Aizawa.”

There are versions of himself that Izuku wishes he could bury.

Summary
Never liked how Hawks never actually found a support system after all the implied stuff he went through, this is basically an angst/comfort fic for me. Feel free to comment any fics similar to Navpike's! Or just comment in general I'm an attention whore. Anyways please read the tags there's some pretty heavy stuff in here even if it's just implied.

Several heroes find their histories brought forward, and things may not be as they should - in the past or the present. How much can a child be saved, when their next six years have already occured?
(Aizawa would like a nap. He did not intend "problem children" to become even more apt, but when has he ever gotten what he wants?)
