A/N: Time for dear old dad to make his appropriately dramatic entrance, though exactly how much of a villain is he? Read on and you'll see!
"Hey, dad…" Izuku groaned, even as Ochaco slapped him.
"Don't 'hey, dad,' him, he's a supervillain! The supervillain! Let me throw him, Deku!" she said.
"Ah, the burdens of love," Hisashi smirked. "Well, miss, you're Ochaco Uraraka, aren't you?"
"How do you know?" Ochaco said.
"Izuku wrote me messages every week," chuckled Hisashi. "A solid 60% of them mentioned you in some fashion. He's more than a little obsessed, I think."
"Wha-hey! Dad! She doesn't need to know that!" Izuku shouted.
"That's so sweet, Deku! I didn't know you'd done that!" said Ochaco.
"Oh, he's done a lot more than that." Hisashi said. "I remember him mentioning that your family was going through some… hard times, owing to lack of business. So I decided to buy it from them! Your parents now officially work for me, and they make some real money."
"Wait, that's how that happened!?" Ochaco said. "Izuku, did you know about that?"
"I hadn't realized he'd done that!" Izuku said. "But uh, back on topic about you being a supervillain…"
"Well, you were half right about All For One; I did send it over to Tomura. But I didn't come with." Hisashi said. "No, I was perfectly safe in my hideout. Still am, actually, and you are free to come here any time! It is, after all, in your name."
Izuku spluttered. "What the – where is this house!? And how does mom not know!?"
"Oh, she knows," Hisashi grinned. "She picked it out, actually, it was meant to be our vacation home! I suppose that is what I'm using it for, really. So seriously, bring your friends, we can all hang out for a weekend, really get to know each other."
"Or just punch your non-existent face in," Izuku said.
"I know that you know that I know that you know you'd never let them do that," said Hisashi. "Also, you can't exactly convict me either-"
"What? Yes I can! You don't have a face; your mugshot is right in the records!" Izuku said.
"Are you sure? A lot of it may have gotten destroyed by Tomura, after all…" Hisashi commented.
"Ah. Crap," said Izuku. "But, wait, are you serious about this weekend trip?"
"Absolutely!" Hisashi grinned. "In fact, bring your whole class, we'll do a big Golden Week vacation!"
"OK… dad… Should I tell mom?" Izuku asked.
"Of course, who do you take me for?" Hisashi asked. "Ah, right, supervillain. But seriously, mark it down! Tell your friends! You can even add that I'm a retired supervillain, since I don't exactly have a Quirk anymore, you made sure of that."
"You're still a major corporate executive," Izuku said.
"Yeah, that's worse!" Ochaco said.
"Careful now, Ochaco, I could let your parents go if you disrespect me more," Hisashi said. "I will say though, if I do end up kicking the bucket, I'm sure Izuku will be more than willing to give you all whatever you need. It's the one thing I always remembered he'd do."
The boy in question spoke up. "Uh, dad, on the subject of giving, can I ask you something?"
"What is it, son?" Hisashi asked.
"I… got your Quirk a few days ago. And mom's, actually. They're a bit slow on the activation but they're definitely your Quirks," Izuku said.
"Oh, that! Yes, well, remember over spring break I came back to talk to you? Well, I decided to add a little something… extra to that," Hisashi explained. "Your mother barely used her Quirk for anything given what it did, so I figured maybe you could have it!"
"Does she know it's gone!?" Izuku demanded.
"After I explained I could transfer Quirks around she was all too willing to let me have it," Hisashi said. "Think of it as an early birthday present. Heaven knows I haven't given you too many of those…"
"You really didn't, but uh, another question: What will you do now?" Izuku asked.
"Well, now that my active villainous machinations are over, I can finally return to be the dad you never really had!" Hisashi said. "It'll be great fun! And remember, we're having a trip during Golden Week! Bring your friends! And go to this address here!" Saying this, he wrote down an address on a small piece of paper he kept with him.
"Uh… OK dad… see you then I guess?" Izuku said. With that, Hisashi's vestige disappeared from the mindscape, leaving everyone else confused.
"What are you waiting for, kid?" Mise asked. "Go bash his head in!"
"He's my DAD! Besides, that counts as vigilante justice since I may have unintentionally prevented him from ever having charges put forward," Izuku said.
"When did that – oh right the police interview. Damn lie detectors, they never work," said Yoichi. "Well, you made this bed, now lie in it."
"Well, in light of all that, I have to say, young Midoriya," Toshinori began. "You really should get your father to buy you a new house. The apartment is decent, but he's a rather well-off corporate executive, I'm sure he's got some cash to spend!"
"I'm not positive on this but I think I may have written a clause in my will that says any of my assets go to Nao and her kids, or barring that, Inko, so, that should include my house…" Nana said.
"…About that," commented Toshinori, tears welling up. "Tenko completely obliterated it. When I'd heard, I came as soon as I could, but he was… gone. The only thing I saw was a pile of rubble… and a crying face split into three separate chunks. I think it may have been Hana."
"I-I… really? That's what happened?" Nana asked. "Why!?"
"His father hated you for abandoning him. That turned into hate for all heroes, like so many others," Toshinori said solemnly. "Tenko wanted to be like you, but his father wouldn't have it. And when his Quirk activated… well, reportedly the last one of them to go was Kotaro. And his head was completely gone. I… I think Tenko had always wanted to do that, deep down."
"God…" Nana said. "I… I had no clue. I think I can find him here, at least, so… maybe I can talk to him?"
Izuku shook his head. "I'd give it time. That's about the only reason that Tenko saw me as a friend, I think: he'd spent time talking with my dad's voice in his head. Hated it all the way, because it was just another father figure trying to control him. When he realized he had family left, he latched onto it and didn't let go, and I think that's what really saved him."
"When did you get so wise?" Nana asked.
"Deku was Quirkless before, you know," Ochaco explained. "He knew what it was like to be stuck in a hole where no one comes to save you. It gave him the right perspective, I think."
"It really did…" Izuku said. "And y'know, I think for once my dad might learn that lesson too. He doesn't have his Quirk anymore, so maybe he'll mellow out."
"Only you would be supportive of a supervillain, though I guess he is family," said Ochaco.
"Yeah, yeah he is," said Izuku. "And there's no way I'd leave my family behind."
"Hey, kid, speaking of family," Daigoro cut in. "Seems like you and gravity girl over there are probably gonna get hitched sooner or later. Now I know normally your parents would be asking about it, but when do you think you guys are having kids?"
"Wha- hey! We're minors! Dammit Mr. Banjo, stop being weird!" Izuku groaned. "As for your question, though, I have had a few ideas as to what might happen…"
"One of his potential kids' Quirks could literally suck out all the oxygen in someone's body!" Ochaco shouted. "When combined with me, that is! GAH! He has an entire notebook of that stuff and what's worse is he wrote it in 30 minutes!"
"Young Midoriya, is that true!?" Toshinori shouted, baffled.
"Uh, yes Mr. Yagi…" Izuku said. "It's just, well, it's a really cool Quirk and I thought it'd be really cool if it passed on so that there would always be someone with it and they could be the next Symbol of Peace, or Hope, or whatever and, well – OW!"
"Quit muttering, Deku!" Ochaco shouted. "And having more of you wouldn't be cool, it'd be a NIGHTMARE! You nearly killed yourself when you went fake vigilante, and that was just because you didn't want us to get hurt that badly! Can you imagine your kids!?"
"I don't see what's wrong with that…" Izuku said.
"There's a line between selflessness and masochism. Everyone here agrees you're a masochist." Nami deadpanned. "Rein it in before you toss yourself into the sun or something."
"Alright, alright, I get it," said Izuku. "But now… I AM NOT HERE!" With that, he and Ochaco exited the mindscape, staring back at the lit up path to 2-A's dorm.
"'I am not here?' Really?" Ochaco said. "Well, anyway, let's get to bed."
"Hey, Ochaco, what was it like in there?" asked Mina.
"Dark, weird, and there were a lot of chairs. It was nice talking to the ghosts though! Although Deku's dad showed up," said Ochaco.
"Why would Midoriya-chan's dad show up? Kero." Tsuyu asked. "He's not a user, was he?"
"Uh, no, he was way worse." Izuku said.
"Hey, why the past tense?" Kyoka asked.
"Yes, that's rather unusual," Momo added.
"Well, y'see… My dad used to be All For One." Izuku explained.
"WHAT!?" everyone else shouted.
"He isn't now! He… actually can't be, since he doesn't have his Quirk anymore." Izuku added. "Oh, and he told me to tell you all that he's inviting all of class 2-A to his vacation home for Golden Week. I understand if you don't want to come, but…"
"Are you kidding!? Your dad's a supervillain! You'll need all the backup you can get!" Mina said.
"If you give me the address, my parents should be able to have the location analyzed," Momo added.
"Yeah, and we'll be right with you, Kero," said Tsuyu.
"He's still got ears, right?" Kyoka asked, earning a nod. "Well in that case, he'll face this music!"
"I offered to throw his vestige in the mindscape!" Ochaco grinned. Then she frowned. "Deku said no, though. Which I still thought was weird."
"He's not currently a supervillain!" Izuku said. "Prisoners get let off on good behavior, and for the past… 6 months he's done literally nothing remotely villainous! Well, except maybe taking my mom's Quirk, but she was OK with that, so…"
"Wait, is that where your new Quirks came from!?" exclaimed Kyoka.
"Apparently," said Izuku. "He said they were an 'early birthday present,' which I guess is nice."
"For being a supervillain-" Momo began.
"Former supervillain," Izuku corrected.
"Former supervillain, apologies," Momo continued, "He is being rather courteous. I can't say a proper vacation isn't in order for all of us."
"So, we're all going?" Izuku asked.
"I shall inform Iida-san, and you can make the announcement tomorrow," said Momo.
"Gotcha, Yaoyorozu-san," said Izuku. "Anyway, it's pretty late, so…"
"Yeah, I'm pooped!" said Mina. "Let's all get some shuteye!"
And with that, they went right ahead and did that.
The next day, Izuku went ahead and announced that Hisashi Midoriya had in fact had and been All For One, though after his Quirk disappeared he was no longer an active villain. He then went on to mention the Golden Week trip, and everyone said they would go. When asked if other parents could come, Izuku decided he might as well call his dad and ask.
"Hey, dad, about that trip next month…" he said.
"Ah, yes, what is it?" Hisashi asked.
"Well, some of my classmates want to know if my parents can come." Izuku explained.
"Of course they can! I'm currently in one house, but really it's actually a resort a 'friend' of mine owns, so there's plenty of space," said Izuku's dad.
"Alright, got it dad. See you then! Love you!" Izuku said. Turning back to the class, he said, "Your parents can come, he's got loads of space there."
"Woah, woah, back up, did you say you loved him!?" shouted Denki.
"Uh, yeah, why? He's my dad." Izuku said.
"Bro, he was a supervillain," added Eijiro.
"Again, was. He isn't anymore!" Izuku said.
"He's like 200 or something!" shouted Sero. "And he doesn't have a face!"
"That's discriminatory!" Izuku retorted. "And besides, if he does cause issues, he doesn't have his Quirk anymore, so…"
"Yeah, he'll be just like Deku when he was a kid!" added Katsuki.
"I never thought I'd say this, but thank you, Kacchan, for the first-hand experience." Izuku muttered.
"Don't fucking mention it," grumbled Katsuki.
With that, class 2-A was decided: They'd head over to the resort Hisashi Midoriya's 'friend' owned for Golden Week. But if anything suspicious happened, they declared, they'd be on the man in an instant.
Soon enough the day came, and Class 2-A was all packed and ready to leave for the resort, though it had been something of a close thing indeed: Endeavor had not taken kindly to their supposed 'abandonment' of UA's campus, especially not Shoto's, but about a day later he'd gotten a call from one Hisashi Midoriya. The businessman had said, in no uncertain terms, that should Endeavor not allow this trip to take place, his hero license would be immediately and irrevocably destroyed. Considering that Endeavor was already on atom-thin ice with the Hero Commission and the general public for the Dabi scandal, he very wisely shut up.
"It has come to my attention that my heroics license is at stake should your 'trip' not take place," he stated simply to the class the morning after. "As such, I am clearing you to leave. However, unless specifically requested or ordered by another Pro Hero, you are not to engage in any hero-related activities. Doing so will be considered vigilantism and you will be punished as adults accordingly."
While Endeavor's reputation was somewhere in subbasement 5, his threats were clear, and so the entire class, save Midoriya, visibly deflated. Midoriya, for his part, seemed… relieved. After their homeroom session was over, Endeavor pulled his son aside for a discussion.
"Shoto, I should not have to tell you this again. Do not disobey this order," he commanded. "It will not be my reputation on the line in that case, it will be yours. From my understanding this Hisashi Midoriya has some very powerful allies in the Hero Commission. You will not upset him."
Shoto nodded, then very quietly whispered, "Hisashi Midoriya is All For One." As he headed to his next class, he added, "Make of that what you will."
Endeavor stood for a moment, stunned at his son's utter certainty of that fact. He resolved to have a meeting with the other staff to discuss their options.
In the meantime, 2-A was on the train with some of their family members acting as chaperones; Inko Midoriya was naturally coming, as was Masaru Bakugo, (his wife Mitsuki didn't want to be anywhere near Hisashi at the moment) and Ochaco's father, Chiso Uraraka was coming as well. (Chiso had explained that part of it was from the fact that Hisashi was his new boss) Tenya's brother Tensei had also offered, and Shoto's sister Fuyumi was more than willing to come too. Mika Jiro, Kyoka's mother, was also with them, and the group's last member was Eiji Yaoyorozu, Momo's extremely well-known and rather overprotective father.
Eventually, the train reached the closest stop, and they found a large coach bus waiting for them on arrival, the words "Midoriya Enterprises," as well as a green planet logo, painted on the sides. Izuku found himself grumbling. "Honestly, I could've probably had a mansion growing up, but no, just a crappy apartment…"
Inko sighed. "I tried to get your father to buy one before you were born but he wasn't as successful as he was now…" she then chuckled, and with a wink, she added, "This resort is under your name, Izuku."
Izuku blinked, then remembered his conversation in the mindscape. "Oh, right it is… Huh."
Kirishima shouted, "Yo, bro, you own this place!?"
Izuku shrugged. "I guess? I didn't know until like a month ago, so…"
Eiji smiled. "Well, Midoriya, I'd heard of your father's corporation before, but I must say, I hadn't realized its rise to prominence was that meteoric."
Chiso grinned, then reached out for a handshake with the corporate magnate. Eiji obliged it heartily. "Chiso Uraraka, Mr. Yaoyorozu. My construction business currently works under the Midoriya umbrella, and thanks to Izuku over there, we've landed a very stable contract with Might Agency. That may explain some things."
"Might Agency?" asked Masaru. "I'd heard from Katsuki that he and Izuku knew All Might fairly well, but I hadn't realized he'd gone that far."
"If it helps, my daughter Ochaco is dating Izuku," Chiso said. "That's probably our in."
At this Tensei had to laugh. "Huh, guess a lot of us are actually pretty well-known now! I mean, I'm a pro hero, Midoriya's dad is a CEO, as are you, Mr. Yaoyorozu. Mr. Uraraka, you're Might Agency's personal contractors now, I've seen Mr. Bakugo's fashion line before, Mrs. Jiro, well, I think everyone here's heard your music, and Shoto, Fuyumi, you two are Endeavor's kids, as much as that means to you…"
Shoto sighed. "That man almost didn't want me on this bus. I'd overheard from Fuyumi that a little 'discussion' took place between him and Midoriya's father that convinced him."
Mika placed a hand on Shoto's shoulder. "Glad that worked out for you, young man." Facing the rest of the group, she pulled out a flash drive and asked, "Mind if I…?" Everyone shook their heads, and she gave the driver the flash drive to plug in and play some new tracks.
As it turned out, one of the tracks was 'Hero Too,' leading to some minor embarrassment from Kyoka, but Mika simply smiled and said, "I know you've always wanted to be a hero, but feel free to stop by and record whenever you like, Kyoka!"
"Th-thanks mom," Kyoka murmured, cheeks still red from blushing.
Eventually, the coach finally stopped in front of the main building of the resort, and what a place it was: it faced the ocean, with several houses stretching across the beach, and the main building itself was a 6 story complex with a massive penthouse and a ludicrously enviable view. Behind the waterfront properties were several apartments, presumably used by other beachgoers whenever they stayed, and there was also an upscale restaurant and fully stocked outdoor bar. "Damn, Midoriya, you own all of this?" Mina said. "I'm so jealous!"
"Alright, time to hit the beach!" shouted Sero, but before he could race off, Hisashi Midoriya stepped out of the building to greet them.
"Ah, welcome! Hisashi Midoriya, at your service." he said warmly, "I hope the trip over went well?"
"You really didn't have to buy all of our tickets, Hisashi," said Masaru.
"Nonsense! It was my plan, it's my son's resort, of course I'd pay!" Hisashi grinned. "Anyway, I imagine most of you are craving some lunch? Come with me, I'll show you where the restaurant is."
Soon enough all 29 people were seated at a massive mashup of several other tables, and all manner of dishes began arriving. Belatedly, the students noted that every single one of them had something they knew they would enjoy every bite of. Eventually, Momo asked why.
Hisashi smiled. "It's thanks to my son, Izuku, over there! I'm sure you've noticed his habit of taking notes and muttering incessantly?" Everyone nodded as Izuku groaned. "Well, at some point he gathered a list of all your favorite foods, so all I had to do was ask him."
"Rather considerate of you, Izuku!" Inko said.
"Thanks mom…" Izuku sighed. "Hey, dad, obviously this is a beach, but what else is there to do?"
"Glad you asked, son," Hisashi said. "There's boats of all makes and models for anyone who wants to take a ride, hiking trails in the surrounding hills, and the river that runs out to this beach has some rapids open for rafting if anyone wants to go. Oh, and of course, power and Wi-Fi for those who need it."
Mineta smirked at this last statement, but out of nowhere he realized Hisashi was glaring at him. "Uh, Mr. Midoriya, sir?"
"I'm onto you, Mineta," the CEO said ominously. "My company manages this resort, including all connections in and out. If one of them catches you… you're going straight back home." Suddenly he smirked. "Besides, why go virtual when the real thing will be right there?"
At this Inko slapped him hard. "HISASHI! THAT IS A TEENAGER!"
"S-sorry… Inko…" Hisashi groaned.
Kaminari laughed. "Huh, Midoriya, didn't realize your dad was like that!"
Izuku shrugged. "Might be from his past, y'know…" Suddenly he stopped, realizing what he'd said. Before he could explain further…
"His past?" Tensei asked, years of hero work seeming to tell him that something was off about the elder Midoriya. "What do you mean?"
Hisashi quickly jumped in to explain. "Ah, it's nothing, Tensei, just that I… well I went on a lot of business trips overseas, didn't leave much time for my family, it… earns a reputation."
Tensei groaned. "Yeah, I've seen it happen. I met Captain Celebrity, y'know?"
"I did not know that!" said Hisashi. "Wait, was that what all that Sky Egg business was about? I'd heard about that all over the news at the time."
"Yep," said Tensei. "He was here for a big conference or something and some explosive villains showed up. Ended up hoisting the Sky Egg for nearly an hour, I think."
Izuku and Hisashi both tuned out the conversation, shouting at each other in the mindscape. "Son, do not blow my cover right now!"
"What cover is there to blow!?" Izuku demanded. "It's not like you do anything villainous anymore and besides, if anyone tries anything we'll get thrown in adult prison."
"That's something I put in, by the way," said Hisashi. "Don't make me have to invoke it."
"I won't, dad," Izuku said.
"Good," Hisashi nodded. "Now, can we have a good vacation?"
With that the two exited the mindscape and tuned back in.
The Midoriyas came back into the conversation just as Kaminari mentioned he'd gotten some exclusive backstage access to one of Kyotoku Jiro's own concerts due to… reasons. Reasons he wouldn't mention, aside from a not-so-subtle nod to Kyoka, prompting a laugh from Mika. Tenya had been a bit livid at this considering it would "significantly cut into his lackluster studies" as he put it, but Izuku added, hey, it was Kaminari's choice to fail his own midterms.
Of course, Kaminari took offense to that, but then Hisashi managed to cut in with, "You know, Tenya, I do believe you have experience with people with 'lackluster studies' as you put it, who are not Denki over there. Does the Crawler ring a bell?"
Tenya froze. "I don't know what you mean, Midoriya-san… I have heard of him, yes, but certainly not…"
"You kidding me?" Tensei asked. "Haimawari and his friends are Idaten's Naruhata branch, have been ever since I got them all hero licenses a few years before Tenya got into UA."
"Wait, you know the Crawler!?" Izuku shouted. "Oh my God his Quirk is so cool! I mean he can fling around, stick to everything, fire off repulsors, honestly he can do a lot-"
"Oi, Deku, shut it with the rambling!" Katsuki hollered. Izuku did so, and eventually the conversation steered in a different direction, before everyone left to head down to the beach.
For a while, everything was going perfectly well; no one had tried to end Hisashi and generally they were all having a great time; Mineta had needed several slaps and at one point Izuku had gone beet red after seeing Ochaco in a swimsuit, but other than that, it was a normal vacation.
Unfortunately, all that would come crashing down, when someone showed up at the gate on day 4. After answering the call to the resort's lobby, they roared, "Which one of you is Hisashi Midoriya!?"
A/N: Place your bets who's at the door, because things are about to get messy! Not for Hisashi Midoriya, obviously, but literally everyone else. Because he's fun like that.
