For prompts: Todoroki using every single Toshi-Izuku interaction to add to his "Izuku is All Might's secret love child' conspiracy board
Tfw its been like two to three days but Many Things have happened in that time. Oops
Uh, anyways–
"Dude. What. The. Fuck."
Sero, Kirishima, and Yaoyorozu stared, wide-eyed and nearly slack-jawed from the futon they currently sat at. Across from them, hanging off the wall was a large pinboard, polaroid pictures and newspapers articles with certain words and pictures circled in with bright red marker tacked onto different places, red string connecting each and every single one of those pictures together.
And in front of that pinboard stood Todoroki Shouto, one of the most powerful students at UA, son of the current Number One Hero, wide-eyed and wild-haired and probably, by definition, out of his fucking mind.
"Listen. I'm not crazy–"
"Literally everything that's happening now is providing evidence to the contrary."
"–but All Might is Midoriya's father."
"That's." Kirishima blinked, once, his brain attempting to process what his classmate was saying. "What?"
"All Might. Is. Midoriya's. Father," Todoroki said, slower, like he was trying to explain quantum physics to a toddler. Or to anyone.
"Todoroki, All Might's never been in a public relationship before," Yaoyorozu replied, slower. Of all of Todoroki's eccentricities, this had to be the weirdest one yet. "Not to mention, all of All Might's speculated relationships have been with men."
"Then at least one of his partners is trans, or he's trans!"
"They don't even look the same!"
"Then Midoriya gets his looks from his mother! They have the same quirk! They practically act the same!" Todoroki threw his hands up in exasperation, frost creeping on the side of his fingers. "I'm still right!"
"Bro, you've met Midoriya's mother."
"Artificial insemination! Adoption! Again, secret love child!"
Todoroki slapped his hand on the board, slightly burning the edges of one of the newspaper clippings. "Look, see here," he said, pointing to the clipping. Kirishima tentatively walked up, squinting at the headline. "Read this."
"'Mystery Samaritans Found Cleaning Up Takoba Beach.'" Kirishima frowned. "So?"
Sero's eyes brightened. "Oh, I remember that! I used to go to the beach all the time with my family," he said. "What's that gotta do with anything?"
"Look at this photo!"
Kirishima turned his eyes towards the photo, frowning. His eyes widened in shock.
"Holy shit, is that Midoriya?"
"Huh, so it is," Yaoyorozu said. "And...is that...?"
"YES!" Todoroki exclaimed, once again slapping his hand on the pinboard and startling his friends. "All Might, as he currently looks now, and Midoriya found at Takoba beach a full year before the school year starts. That means they knew each other before the school year started!"
"You repeated yourself."
"I know I know I know but why," Todoroki pressed, taking a deep breath, "why would All Might, in his weakened state before Kamino, be seen with Midoriya unless...unless that was his secret son."
He clapped his hands together just as he was finishing his point, clearly pleased by his argument. The three stared back at him, slightly alarmed.
"Or...maybe he just met him recently and they decided to clean the beach together," Yaoyorozu said tentatively. "It could happen."
"Or, or they decided to train for Midoriya's UA Exam together by lifting appliances at the beach! Or working out around the beach a year before!" he protested. "My father used to make me train by lifting up heavy objects ten times my size and pushing my quirk before the UA exam too!"
Sero frowned. "Todo, I know good parenting is a foreign concept to you, but comparing your relationship with your dad to Midoriya and All Might maybe isn't the best of ideas."
"I'm pretty sure Iida used to train with his hero brother in a very normal way," Todoroki nearly fucking pouted. The guy was really fired up– metaphorically and a little bit literally, judging by his floor. "But, but anyway, what I'm trying to say was that All Might, trying to make sure Midoriya would be strong enough for the entrance exam, made him clean up the beach because he was helping to train his son!"
Kirishima stared at him. "Bro."
"I'm right! Not to mention, why would he be in his thinner state around Midoriya if he wasn't his son?!"
"Maybe he told him about the weakened form back then by accident?" Sero said. "Todoroki, seriously. You're looking too deep into this."
"I agree," Yaoyorozu said. She loved her friend, truly, but as good as it was for Todoroki to exhibit any other emotion besides confusion and rage, this couldn't be healthy for him.
Todoroki groaned. "Okay, okay, fine. Exhibit B!" He pointed to a picture of All Might and Midoriya walking into All Might's office. "They eat lunch together! Who does that with a teacher?!"
Kirishima hummed. "Okay, I'll give you that one," he said, looking back at the others. "You gotta admit, that is a little suspicious."
"You forget, Midoriya broke his bones a lot at the beginning of the year just by activating his quirk," Yaoyorozu said, calmly. "As the Heroics teacher, All Might would want to make sure they can find a way for Midoriya to improve his quirk use without breaking his bones, so it would make sense for All Might to meet up with Midoriya out of class."
"But why continuously?!" Todoroki pressed. "Even after Midoriya got a handle of his quirk?!"
Yaoyorozu frowned. "Well, Bakugo meets with them now. Is Bakugo All Might's son too?"
"Details, details," Todoroki said with a wave of his hand. "Bakugo's practically Midoirya's boyfriend anyways. All Might probably wants to vet him or something."
"Somehow I believe that less than your 'All Might is Midoriya's dad' theory."
"They're going to get together, just you wait," Todoroki said. "Anyways, back to business. It's not just at school too! Even now that we're in the dorms, lately All Might will eat with Midoriya, alone, just the two of them!"
He pointed to another picture of Midoriya and All Might eating meat buns on a bench, no one else in sight, lightly chatting. "See! It would make sense if All Might ate with any one of us, or if there was a bigger crowd, but it's just those two! That's a normal parenting thing, right?"
"Dude how did you even get that picture."
"Irrelevant."
Yaoyorozu ran her eyes over the full board again, wincing internally. As...off-putting as her friend's efforts were, he did have a point. All Might's actions towards Midoriya were unprecedented of a teacher, Aizawa would certainly never be caught dead with any of them. And sure, they simply could be good friends who met a little before the Takoba news article picture, friends could be of all ages after all, but with the way All Might treated Midoriya daily, it was getting more and more likely that Todoroki's theory was correct. Which had some very interesting implications and also a media shitstorm on its way if it was true.
"And," Todoroki continued, now rambling as fast as Midoriya was, "did you know that All Might visited the Midoriya's to talk about the dorm system alone?"
Kirishima's mouth dropped. "Seriously?"
Todoroki nodded, eyes wide and a small smile on his face. "Aizawa-sensei told us himself back when he asked my father if I could stay in the dorms! My father asked where All Might was and Aizawa-sensei told him that they split up right before the Midoriya's!"
Sero's eyes widened. "Okay, I will admit that that's weird."
"I know right?!" Todoroki exclaimed, out of breath and restlessly pacing the floor. "Not only that, but All Might was one of the first people Midoriya texted right after he got his hero license. And Midoriya ended up interning with a hero who All Might knows directly and worked with Nighteye during his work-study who's All Might's only sidekick! And then Midoriya was invited personally to I-Island by All Might! And–"
Knock knock.
The group froze.
"Young Todoroki? Can I speak with you?"
Fuck.
Todoroki tentatively walked over to his door, opening it just enough to find All Might standing behind it, a worried expression on his face. "Are you all alright? The kids downstairs reported a lot of yelling, and I think you may have frozen and burnt through your floor?"
Todoroki looked back at his floor, which now looked slightly more like the training room back home than it did his dorm room. "Right. I can pay for that."
"No need my boy, just make sure it doesn't happen again or I think Aizawa'll have all of our heads," All Might chuckled. He then frowned, slightly opening the door more. "What on Earth is that?"
His eyes were pointed directly behind Todoroki, to the pinboard the high schooler had been deliriously gesturing towards for the past few minutes. Kirishima, Sero, and Yaoyorozu stared at each other awkwardly, shuffling their feet.
"Um...well, y'see–"
"All Might, is Midoriya your illegitimate child?"
The air paused. Everyone turned their eyes to the teen.
All Might blinked. "I'm sorry...what?"
WHAT THE FUCK, TODOROKI?!
"Todoroki, bro, you can't just ask shit like that!" Kirishima exclaimed, who now, like the many people around him, was going through all the stages of grief. "That's not one of those things you can just ask people!"
Todoroki tilted his head. "I asked Midoriya."
"YOU ASKED MIDORIYA?!"
"I–"
The kids now directed their attention back to All Might, who had managed to shake himself out of his stupor and somehow made his way to the pinboard. "I'm not...young Todoroki, believe me when I say I'm 100% sure I'm not Midoriya's biological father," he said, rapidly glancing back and forth from the board to Todoroki. "As...creepily impressive as this is," he continued, gesturing to the entirety of the board, "I've never had a child, and besides, young Midoriya's biological father works overseas, in America."
He pointed to the slightly burnt newspaper clipping of Takoba beach, looking back at Todoroki. "Is this about the Takoba beach cleaning?"
Todoroki nodded.
"Huh." All Might turned to the clipping, a strange, soft, thoughtful look on his face. "I didn't know they did a report about it." He turned back to Todoroki. "May I keep this?"
Todoroki nodded again, even slower, and a delighted smile appeared on All Might's face. The four students watched with wide eyes as he took the newspaper clipping in one hand and the pin in between his other fingers, gently lifting the pin from where it had been embedded in the pin board, lifting the newspaper clipping from its place, and placing the pin back where he had found it. Seconds passed. All Might rubbing his thumb over the picture in the newspaper with a soft chuckle. He then gently folded it, each crease careful not to tear the newspaper apart, before placing it in the pocket of his tracksuit.
Then, as if he remembered that there were other people in the room, he turned to Todoroki. "Ah, Aizawa-kun said that you had redecorated your room yourself, yes?"
Todoroki nodded, still stunned. "Perfect! The bots will be up here in a few minutes or so to repair your floor, and then refurbish your room any way you see fit." All Might clapped his hands together, a bright smile on his face. "Just try not to do it as much, alright? And please stop stalking young Midoriya and I. I don't know how many times I can catch you in the act before telling him that one of his best friend's have been stalking us to obtain proof of our non-existant biological relationship."
"You saw me?"
"Young Todoroki, I've been the number one hero for three and a half decades."
"Oh." Todoroki frowned. "Sorry."
"Just don't let it happen again, please." All Might took a heavy sigh before finally addressing the others in the room. "Young Kirishima, Yaoyorozu, and Sero, I'll be seeing you in class tomorrow. Plus Ultra!"
"See you!"
"See you tomorrow All Might!"
All Might left the room, closing the door behind him, leaving Todoroki, Kirishima, Sero, and Yaoyorozu in the room, waiting for the repair bots to arrive, silent and bewildered with what had just transpired in the past ten minutes. The four of them couldn't move, only the sound of breathing being proof that any of them were even alive. After what felt like several, long, painstaking seconds, Todoroki turned to his friends.
"Y'know, All Might worked in America for a while."
"FOR GOD'S SAKE, TODOROKI."
