Many years ago, in the city of Los Angeles, California, two villains were running from having just robbed a large casino of millions of dollars. The larger villain was multi-armed and beast-like, with two rows of teeth in his mouth. Riding atop him was a villain in a red jumpsuit, cackling like a maniac.
Already, the police and many Pro Heroes were on their tails. The villains did their best to try and avoid them, quickly jumping into civilian traffic. Before they could crush a family underneath them, they were sent flying by a massive fist flying toward them.
"Fear not citizens! Everything is fine! You're safe because I am here!"
A tall, muscular young adult man with blonde hair and shining electric blue eyes smiled as he stood proud, the two daughters of the family gazing at him in awe. Even more so when a beautiful woman in white royal-looking robes and flowing multi-colored hair floated down on wings like those of an angel.
"You certainly know how to be dramatic, Toshi."
"If I'm going to inspire people, I need a catchphrase! Something they can identify with, even if it's corny!"
This was in fact Toshinori Yagi and Amaterasu Taiyo AKA All-Might and Celestia, when they were college-age. The two were starting to make a name for themselves in America before returning to Japan.
"Who the hell do you think you are?!" The smaller villain asked angrily.
"We're just humble tourists, nothing more," Celestia said.
"Well, let me give you a proper welcome then!"
The smaller villain used his Quirk to turn his arms into rocket launchers, firing a set of missiles at the two, only for Celestia to destroy them with a simple beam of solar energy. Of course, the two villains took the time to make a break for it.
"Typical, cowards running when they realize there's someone bigger than them." Toshinori huffed.
That's when a third man, a brown-haired American, came driving in on what looked like a modified drag racer.
"You guys got ahead of yourselves."
Toshinori hopped into the car as Celestia spread her wings, ready to take flight.
"These guys are fast, Dave. Better put pedal to the metal!"
David Shield chuckled. "Does your body always move before you think?"
"Hey, that sort of attitude is what got Nimbus' attention." Celestia giggled.
"And the sort of person whom I hope to one day succeed me," Toshi added.
"One step at a time. First, you gotta become a hero in your own right." David said.
The Allmobile raced after the two villains, Celestia being the eyes in the sky as she flew above them. David directed the F-Unit, a secondary remote module for the Allmobile, to track the villains down.
"They caught up! How are they so fast?!" The Beast Villain exclaimed when he saw the three tailing him and his buddy.
"Dammit! Get off our backs!" The Red Villain snapped as he fired more rockets.
David launched a specialized missile of his own, which exploded into a spray of bubbles to contain the rockets and their blasts.
"We gotta end this quick, or we're gonna be late for the lecture!" David said.
"Luna is certainly going to get on my case if we don't make it in time!" Celestia added.
"Well, we did intend to finish this quick!" Toshinori smirked as he leaped off the front of the Allmobile. The villains were gobsmacked and tried to fire more rockets at him, but he easily dodged them, though the explosions burned his clothes, revealing his hero costume underneath.
"Let's give 'em the finisher, Tia!"
"Right!"
The two flew towards the villains, boxing them in as Celestia charged her fists with solar energy while Toshinori spiraled with a right hook.
"SUN SALUTATION!"
Celestia nailed the Red Villain right in his chin, while Toshinori nailed the Beast Villain in the middle of his face. Both were sent hurtling to the ground, going unconscious upon impact.
After helping the police and the local Pros round up the villains, Toshinori, Celestia, and David drove down the road to college.
"Amazing work, Dave. Thanks to this new costume, that was a cinch. Now we should be able to make it to class on time." Toshinori smiled.
David nodded. "I hope so, otherwise I don't know if we'll be able to pass the course."
Just then, the Allmobile's police scanner came in about a bus jacking.
"It seems we have one last little detour to make..." Celestia hummed as she spread her wings and ejected from her seat, taking flight.
"Hold the elevator, Tia!" Toshinori called out.
David chuckled and shook his head. "You're both way too reckless for good guys. Who knew being a hero would be so much work?"
He brought in the F-Unit to link with the Allmobile as Toshinori laughed, the three flying off.
"Tell you what, how about I buy you both lunch when this is over?"
Toshinori awoke from the dream, more like a fond memory, from his youth as he saw Izuku looking at him excitedly.
"We're almost at I-Island, Toshinori-Sensei!"
The rest of the Mane 6, Marco, and Celestia were also flying with the two. Pinkie had her face excitedly squished against the window, bouncing in her seat.
"There it is, the floating artificial island. Home to over 10,000 scientists." Twilight said. "Oh, I just can't wait to see what sort of scientific advancements we'll find today!"
"Easy there, my faithful student." Celestia gently said, putting a hand on Twilight's shoulder. "Let's wait until we touch down first."
"Attention passengers, the plane is now beginning its descent to I-Island."
"That's my cue," Toshinori said as he buffed up into his All-Might Form before taking off his clothes to reveal he was wearing his hero costume underneath.
"Honestly, I have to admire how prepared you are for this event." Rarity noted.
"You all should get changed as well," Celestia said. "I'm sure plenty of people will be happy to see the young budding heroes in person."
Izuku and the Mane 6 nodded while Marco just reclined in his chair, already technically wearing a costume since his natural carapace suited him just fine.
The Mane 6, Izuku, Marco, All-Might, and Celestia were passing through immigration when they decided to pass the time with some trivia.
"Young Midoriya, here's a trivia question; How was I-Island created?"
"It was created so that the world's brightest minds could come together to research anomalies and create new hero support items," Izuku said. "The island was designed to float and comes with an outer layer of telekill alloy, perfect for preventing villains from finding and infiltrating it. The security system is on par with Tartarus, so there's virtually no crime whatsoever."
"Easy there, Izu. Don't need you going over-analysis again." Twilight giggled as she pinched Izuku's lips shut playfully.
"Says Princess OCD." Rainbow Dash snickered as Twilight gave her a dirty look.
The scans showed everyone's IDs, including their chosen Hero Names. As they came out of the airport, Izuku and his friends gasped in amazement at all the attractions set up.
"Boy howdy, the pictures sure didn't do this place justice." Applejack whistled as she put a hand on her hat.
Toshinori nodded. "I-Island permits everyone here to use their Quirks freely, unlike in Japan. As a result, all the pavilions are jam-packed. Be sure to make some time for everything while we're here. Now, the hotel should be nearby..."
Unfortunately, All-Might was spotted by a female greeter, who ended up indirectly alerting many fans. Izuku took to the air using [Float] while Twilight and Rainbow sprouted their wings to carry their friends over the growing crowds.
"Oh dear, I don't know how I'll be able to handle that kind of publicity..." Fluttershy worriedly said.
Celestia quickly carried Toshinori as well, surprising everyone with how she could carry his musclebound form despite her slender, graceful figure.
"Sorry, autographs will have to wait, everyone!" Celestia called to the fans as they cried out for her and All-Might.
"It's a good thing we managed to lose them..." All-Might sighed as everyone had settled down. "I don't want us to be late."
"I can agree with you that it's never good to be late unless it's fashionable." Rarity said. "But what do you wish to not be late for?"
"It has to do with why me and Celestia invited you all here," Toshinori explained. "We wanted to drop in on an old friend of ours. We haven't seen him in a very long time."
"We'd be all for it! Any friend of All-Might and Celestia has to be super cool!" Pinkie beamed excitedly.
Celestia giggled. "Well, he's a bit straight-laced but he was always willing to lend a helping hand. He's aware of [One For All], but we never got around to telling him that Toshi passed it down yet."
Just then, a young woman came bounding in on what looked like a pogo stick. All-Might and Celestia quickly recognized her as she approached.
"Hey, Uncle Might! Auntie Tia! You finally made it!"
She leaped right into Toshinori's awaiting arms as he laughed and spun her around.
"Melissa! Good to see you again, my girl! You've gotten taller since the last time I saw you!"
"You've certainly blossomed into such a beautiful young woman." Celestia smiled.
"Yeah, it's been forever!" The girl, Melissa, laughed. "Did you two finally get engaged?"
Celestia blushed while All-Might chuckled bashfully.
"Not yet, I'm afraid..."
"So, where's David?" Celestia asked, wanting to quickly change the subject.
"Dad's in his lab right now. Apparently, he had to do some cleaning since he decided to shut down some research he and the board felt was too dangerous. Actually, he has no idea you're even here. I wanted it to be a surprise to cheer him up." Melissa explained.
"Well, anything I can do to put a smile on an old friend's face." All-Might beamed as he then turned to Izuku. "Oh, I almost forgot! Young Midoriya, this is Melissa Shield. She's the daughter of David Shield, the old friend I was telling you about. It was her that sent the invitation."
"N-Nice to meet you..." Izuku stuttered, blushing at how pretty Melissa was. Twilight pouted and jealously elbowed him in response.
"Always great making new friends!" Pinkie cheered as she zipped up to Melissa and shook her hand rapidly.
"A-A pleasure to meet you too!" Melissa stuttered, trying to stop her hand from shaking after Pinkie let it go.
"Well, glad to see introductions are going swimmingly." Celestia smiled. "But it's best we don't keep David waiting."
Melissa nodded as she picked up her pogo stick, which quickly morphed into a wristwatch.
"Dang fancy tech..." Applejack muttered as Melissa giggled.
"Yeah, all this, and we're still behind on getting space travel officially underway. Come on, follow me!"
Meanwhile, a group of shady men in concealing coats were coming out of the airport. The leader made a call from his smartphone.
"We successfully infiltrated the expo without a problem. When do the goods arrive?"
"3 PM. You'll find them at Gate 66."
"Okay, we'll be waiting," the leader said before making another call on his phone.
"Hello, welcome to McDonald's, can I take your order?"
"Uh, can I get a Diet Coke?" Asked one of the men from behind.
"Spicy Chicken McSandwich, a McRib, four Large Fries, three Quarter Pounders, one without any pickles, two Big Macs, 20 piece Chicken McNuggets, three Egg McMuffins, a Large Dr. Pepper, a Large Sprite, and a Large Coca-Cola."
"And a Diet Coke!" The same guy from behind called, making the leader sigh.
"And a Small Diet Coke."
"Awwww..."
David Shield was checking his tablet for anything that might have been missed as he stood in the empty research lab.
"Professor Shield?," a middle-aged man asked, "I finished putting the equipment away like you asked."
David smiled. "Thanks, Sam. Guess we can both take a break now."
Samuel Abraham nodded. "Are you sure about this? The research you created..."
"I know, Sam. I wanted to use it to help All-Might but Celestia helped me realize that it'd be terrible if any villains got their hands on it."
"I see," Sam said sadly. "Well, maybe you should get some lunch with Melissa."
"Oh, she's busy with independent research. That girl just cannot stop doing everything she can to learn." David chuckled. "She got it from her mother, after all."
"I'm as much your daughter as I was hers, you know."
David and Sam turned to see Melissa in the doorway.
"Well, here's a surprise. What are you doing here all of a sudden?"
"Well, since you had to scrap your last project, which you poured so much time and effort into," Melissa said. "I thought it would be nice to cheer you up with a special surprise guest. Two of them, to be exact!"
David was curious about what his daughter meant until he saw two very familiar figures he hadn't seen in a long time and beamed.
"I AM HERE! SHAKING WITH EMOTION FOR OUR HEARTFELT REUNION!" All-Might called out.
"How have you been, Dave?" Celestia smiled warmly.
"Toshi! Tia!" David laughed as the three got into a group hug. Sam awkwardly decided to see himself out to give them privacy.
"What are you two doing here?"
"We came all the way here just to see you, old chum!" All-Might laughed. "Melissa sent us an invite for the expo and we just had to come over!"
"I'm glad she did," David said before frowning. "How's Luna doing...did you find her?"
Celestia sadly shook her head. "No, but we haven't stopped looking. I know we'll find her eventually."
"Well, let's not dwell on it for right now," David said. "I missed you guys."
"On that note, we've also brought in our faithful students," Celestia said as she gestured for Izuku, the Mane 6, and Marco to come in.
"Oh my god, David Shield!" Izuku excitedly called out. "A top scientist in the field of Quirk Research, and All-Might's sidekick during the early years of his hero career! He was the one who designed all of All-Might's most notable costumes! I never thought I'd get to meet him in real life!"
"Guess introductions aren't needed, huh?" David asked as Melissa giggled at Izuku's enthusiasm.
"Yeah, he does that a lot when he's excited," Twilight said. "My name is Twilight Sparkle, I'm Celestia's personal protege and he's Izuku Midoriya. These are our friends; Rainbow Dash, Applejack, Rarity, Fluttershy, Pinkie Pie, and Marco Nui."
"Don't forget Click!" Marco pointed out, his companion chirping on his shoulder.
"David, I feel like you might have already guessed but Young Midoriya here..." All-Might began but David nodded, his eyes solemn.
"He's the one, isn't he? The one you chose?"
"He certainly proved himself worthy. You should have seen it, old friend." Celestia smiled.
"Uh, should we be discussing that with Melissa here?" Rainbow Dash asked. "Not to be rude or anything, but..."
"Oh, I actually already know." Melissa clarified. "Dad told me when I was growing up."
"Well, ain't that handy!" Applejack said.
"Oh thank goodness, that saved a lot of awkward conversations from happening for sure..." Fluttershy sighed in relief.
David chuckled. "Listen, I'd like to get the chance to catch up with Toshi and Tia. How about you kids go and enjoy the expo?"
"Oh boy! I'm looking forward to seeing what technology this world has to offer!" Marco cheered.
The kids all left together as Toshinori deflated back to his regular form, sighing in relief as he stretched his back out.
"Phew... Sometimes it can be tiring to keep my Quirk up for extended periods. Not like when we were younger."
David nodded. "Maybe we should have you examined, just to be safe."
I figured it'd be easier on my psyche to separate this into parts.
