Izuku sat in the bar with a burner phone his father(?) gave him. Things felt like they couldn't progress until they knew for sure whether or not they were related. Sure, there were other important things to address still, like what he was going to do with his life now that he was on the run from the law, or training his quirk after suppressing it for a decade, but this took precedence.

He wished he could just call his mother and make sure, but as the friendly bartender explained, it was probably a bad idea since she was under police surveillance. So he needed to call someone that wasn't currently being watched by heroes and police that could and would track the call but still knew enough to confirm or deny.

This narrowed down his options to one person. Mitsuki Bakugou. She was his mom's confidant and the only other person he knew who had that information. He'd asked her once if his mom had told her, and her response had been "Told me?! I was there when those idiots met, but that doesn't mean I'll tell you anything you little brat. Your mom has good reason for making you wait until you're an adult."

As the phone rang he hoped he could finally get a straight answer instead of just trying to guess.

"Who the fuck is calling me at eight am, on a Saturday? If you aren't dying or worse, you're about to be."

He laughed a little, not realizing how nice it would be to hear the voice of someone he knew after all of the craziness that had happened over the last 24 hours. "Hey auntie."

There was an audible gasp over the phone. "Holy shit, is that you, Izuku? I thought you were still locked up. Which is bullshit by the way, thanks for saving my brat's life."

"Thanks auntie, um, well I was in prison, but I was broken out."

"Who did that, and where are you?"

"Well, you see, that's why I'm calling actually. I'm pretty sure the person who broke me out is my dad."

She started laughing loudly. "Ha! Yeah, that sounds like something he'd do. That man isn't really one for subtlety or small gestures. And you called me to make sure he is who he says he is?"

"Yeah, it's honestly a bit hard to believe."

He didn't want to share around the fact that his dad had serious memory issues so he didn't mention that his dad had no idea either and they were both guessing.

"Well, I can see why they didn't share your daring escape with the news then. Because if law enforcement has any idea that your dad was involved then they're gonna have to handle this very carefully. Hell, they might just ignore it completely and decide it's not worth it rather to go up against him."

Ok, so she did know how big of a deal he was in the underworld and how much of a threat he was.

"Yeah, I could imagine it would be kind of a mess if they sent heroes to arrest him."

She laughed loudly again. "Ha! 'Kind of a mess' is an understatement, but you're not wrong. Well, even if he is a bit of an idiot in my opinion, you'll be safe with him. I don't know his real name, since he's touchy about that sort of thing, but yeah, even if it's hard to believe, your dad really is All-"

The phone disintegrated as Toumura grabbed it from him. "Hey! Why'd you do that?!"

"Because you were talking with some NPC about Sensei like some sort of traitor. The heroes think he's dead, and if your little friend there starts telling people that he's very much alive, then they will start hunting him down again!"

Izuku hung his head. "I'm sorry, I didn't know."

"Where did you even get a phone? That shouldn't be in your inventory."

"Oh, uh, dad gave it to me so I could call him or Kurogiri for help in an emergency."

"And you use it instead to put everyone in danger! You must have forgotten to put any stats in intelligence, but from the looks of you, you're not exactly a fighter class either. So what good are you if you're both dumb and weak?"

The best defense he was able to muster was a mumbled "Shut up."

"Sure, you caught Sensei's attention when you killed a guy, but he just found your quirk interesting. You don't belong here and I won't let you take my place!"

"Shut up!" Izuku could feel the control on his quirk slipping. Tomura's quirk felt like swirling dust that would destroy anything it touched, and he could tell it was focused in his hands. He had gone an entire decade without using his quirk once, but now that he had, it was like Pandora's box had been opened.

"Is that all you're able to say?!"

It had become easy to ignore before the incident with the slime villain, but now that he'd given in once it was so much harder to contain that desire to take all of the cool quirks he saw. And besides, he was already considered a villain, so why should he keep holding himself back?

"SHUT UP!" And with that he made a swiping motion with his hand, as if he were snatching something out of the air.

They both went silent as they felt the quirk change owners.

"Hey! Give that back!"

"My quirk doesn't work like that, I can't give quirks, only take them."

"That's so dumb, what if you take a quirk you don't want?" At first he wasn't sure why Shigaraki wasn't more upset, but then he remembered that they had access to someone who could transfer quirks, so maybe it wasn't as big of a deal here since his dad could undo this.

"Well, your quirk can't be undone either. What happens if you destroy something you didn't want to?"

"Yeah, but I want to destroy everything, does that mean you want to take every quirk like some shitty klepto rogue?"

"Not all of them, and I don't think that I would actually want to follow through most of the time, I just think quirks are super interesting, I see a cool quirk and I just really want to try it out and experiment with it."

"Ugh, you're such a nerd." He stomped over to the television in the bar like an angry child. "Sensei, your dumb brat took my quirk."

"I am aware. I've been listening since before you entered the room, Tomura."

"I want it back!"

"I see, Kurogiri, please warp both boys to my location so we can remedy this issue."

Within moments a swirl of purple mist surrounded them and dropped them off in the room he had been in before, with the life support equipment and many monitors. The old villain waved them over to his chair, when they approached he reached out and placed a hand on each of their heads.

Even though it didn't hurt, he certainly didn't like the feeling. The closest thing he could compare it to was having a toy taken from him before he finished playing with it. He wasn't a greedy person by nature, but quirks were just so interesting and what better way to study one than to use it yourself? He still had questions and ideas for the disintegration quirk but had to give it back anyways.

He then heard his father laughing. "Oh, I know that expression, but I've never seen it from the outside before. Giving back quirks is never as much fun as taking them, is it?"

Izuku simply shook his head, feeling embarrassed at being called out. "Um, how can you see me? Is it a quirk?"

The man smiled. "We can discuss that in a moment. Tomura, Kurogiri can bring you back to the bar now unless you wish to join our conversation on quirk applications?"

"Ugh, yeah, I'll go."

With another swirl of purple mist they were alone again. "So. Unless I misheard your conversation in the bar, you've confirmed that you truly are my son."

Izuku nodded. "Yeah, I was talking to my mom's best friend. Apparently she knew you as well."

"In the future I would have preferred that you talk to me before doing something like that. As Tomura already stated, it could have put us in danger, but in this case I believe it was warranted."

"Yeah, that makes sense."

"Do not look so guilty, there is no shame in such a simple mistake, simply talk to me first next time, if it were that dire I would have intervened. Now, with that out of the way, let's talk about more interesting things. The main way I see is with a quirk that is called 'Surveillance', it lets me hack into cameras and look through them as if they were my own eyes."

"Ohhhh. So that's why you always have that monitor on in the bar! You use the camera on it to see what is going on."

"Correct, it allows me to go about my day without too much issue. I also use an infrared quirk that allows me to sense heat signatures. Those two along with enhanced hearing prevent me from being hampered or weakened by not having eyes."

Izuku's face had lit up with joy as he contemplated all the ways those quirks could work together. "Can you sense heat signatures through the cameras you hack into, or do the quirks have to function separately? Would it be possible to regrow your eyes through a regeneration quirk? Nevermind, that wouldn't work unless you had the quirk prior to your injury since it would only ever heal you to the state you were in when you got the quirk."

His father's smile matched his own. "You're correct on both counts. A regeneration quirk wouldn't help and I can use the infrared quirk through the cameras, even if they aren't equipped with infrared capabilities. Now, I have something for you to look through."

He handed a book to Izuku that was filled with laminated pockets for cards to be stored in. As he looked through it he found that every single card had the name and description of a quirk.

"These are all quirks you have?"

"Yep, I store the information like that so it's easy to keep track of what I do and don't have. I'm glad I wrote it down instead of relying on my memory. The last thing I needed was trying to figure out all of my quirks through trial and error."

Izuku nodded slowly and spoke softly. "You really forgot that much?"

"Yes. I'm over one hundred and fifty years old, and there are entire decades that are just missing. I never kept a journal or anything, and I kept myself out of any public records, so it's likely that I'll never actually know about large portions of my life. All because that bastard All Might took it from me."

"You really hate him, don't you?"

"How could I not? Could you imagine the pain of finding out that you had a child and a woman you loved, but can't remember a single thing about them? Do I have other children? Other past lovers over the years that I've forgotten existed? He took my loved ones from me in a way I hope you never have to understand. I raised Tomura since he was barely four years old, and when I woke up from being put back together I barely recognized him."

"Oh God, that's awful."

"That man has not exactly been kind to either of us." He sighed briefly before composing himself. "Let's not worry about that for now, we can focus on making new memories instead of grieving the ones lost. The reason I wanted you to look through that is there are plenty of quirks I can't use anymore, as I mentioned before. Since I've been trying to stay under the radar the last few years I haven't had a way to get rid of them without gaining attention, so I've simply held onto them. So, anything with a black x at the bottom that you want is free for the taking."

He chuckled to himself, "Even if it isn't marked, I'm sure I can part with a few quirks that you find particularly interesting. Consider it a replacement for the many birthdays I've missed."

Izuku was ecstatic, there must have been hundreds, maybe even thousands of cards in the book, each of them a unique quirk. He was like a kid in a candy shop as he analysed every single one in the book and threw question after question at his father.

"I know you're having fun but you need to take a break."

"What? How come?"

"Well, you've been sitting on the floor flipping back and forth between those pages for about four hours and it's lunch time."

"What? No way, it hasn't been that long…" he looked over at the clock on the wall and found that it in fact had been that long.

"Oh, oops. I just got distracted."

"It's fine, nothing wrong with it. But I'll have Kurogiri warp over a sandwich for you."

"Um, what about you? Wouldn't we have lunch together?"

"I haven't eaten food in quite a while. I have a photosynthesis quirk, as long as I drink water and get enough sun from the skylight I put in, then I don't need to eat." he looked down at the green haired boy who nodded but seemed a little disappointed. "But you make a fair point, even if it's less convenient, I think it would be lovely to have a lunch together."

Only a few hours away, a very stressed Inko paced back and forth in her living room. Mitsuki sat on her couch, having thought she was bringing good news.

"What do you mean he's with his father?!"

"It's like I just told you, he called me to make sure the guy he was with was really his dad and I confirmed that his dad was All Might."

"Did he explicitly say he was with All Might?"

She thought for a second. "No, I don't think he did, but it really seemed like we were talking about the same guy. What's the issue Inko, we're clearly not on the same page."

"The issue is that All Might isn't with Izuku, he's hiding in the kitchen because you intimidate him. Which leaves me to wonder, who the hell has my son?!"

I did my best to try and humanize All for One a bit, but that won't change the fact that he is a man who has/will do terrible and evil things.

It was so much fun writing the Mitsuki phone call and just finding more and more ways to refer to all might/all for one in ways that could be either of them.

anyways, hope you all enjoyed this chapter, please comment any thoughts or questions you have.
