"That is... quite the story, young man," All Might said, sitting beside Midoriya, who was still in his Pyronite form. The two sat around a campfire, the dark night illuminated by the orange flames of the fire and the green flames flickering from Midoriya's body as he retold how the mysterious device had latched onto him.

"It's getting late. Mom must be so worried about me."

"Well, we can't exactly have you show up looking like... this. Your mother will have questions that we don't have answers for."

"Yeah, I guess it would be pretty bad if I showed up looking like a monster in front of her."

"You're not a monster—you're an alien," All Might corrected, though his tone was gentle. Midoriya looked confused. "I-I-I mean, just look at yourself. What else could you be? Anyway, we should focus on figuring out how to turn you back."

Midoriya immediately panicked, trying to think of a way but coming up empty.

"Well, young Midoriya, you've studied a lot about quirks. How do transformation types usually revert back?"

Midoriya put a finger to his chin, thinking through his vast knowledge of quirks. "There are generally two ways. One, there's a time limit. It can vary from 10 minutes to several hours, depending on a person's stamina and physical condition."

All Might nodded thoughtfully. "Your recent training has significantly increased your stamina. Even after training for more than three hours today, you don't seem fatigued."

Midoriya continued, "The other way is through mastery of the quirk. But usually, people revert back if they're knocked out or completely exhausted."

"It's been over an hour since you transformed, so I believe it's the latter," All Might reasoned. "At this rate, you could stay like this for several more hours."

"Hours?!" Midoriya exclaimed, panic rising in his voice. "Wh-what are we gonna do?"

"I have an idea... but it might hurt. A lot."

With a puff of smoke, All Might transformed into his hero form. Midoriya quickly realized his intentions as the pro hero cracked his knuckles.

Midoriya gulped nervously. "This is gonna hurt, isn't it?"

With a powerful smash, All Might delivered a right hook, sending the boy flying. As Izuku landed, a green flash illuminated the area. All Might looked over to see the boy knocked out, now back in his human form.

"He'll be out for about an hour... I should inform Nezu. If the Omnitrix is here, then he won't be far behind."

All Might pulled out his phone and dialed a number. After a few rings, someone answered.

"Toshinori? To what do I owe this call?"

"Nezu, we may have a problem. I recently met a quirkless boy with an incredible amount of heroic potential…"

"I see. You're planning to give this young man—"

"The boy's name is Izuku Midoriya," All Might interrupted.

On the other end, Nezu froze, his eyes widening as if he'd seen a ghost. His cup of tea slipped from his grasp.

"I see... If he's anything like him, then I believe you've made the right choice. I do miss that man—his constant muttering," Nezu mused, momentarily lost in thought. But he quickly snapped back to the present.

"Well, something extraordinary happened today. Do you remember Hisashi's last mission? I wasn't given all the details since I'm not exactly a Plumber."

"Yes, I remember," Nezu replied. "Hisashi was tasked with protecting a piece of DNA technology from Vilgax's clutches. The battle raged across the galaxy, and after Vilgax disappeared, rumors spread that the DNA technology was, in fact, the Omnitrix—the most powerful device in the universe. But no one has ever confirmed its existence."

"Well, the rumors are true. The Omnitrix does exist, and it's attached to one Izuku Midoriya."

Nezu closed his eyes, processing the information. "That's... troubling. Please bring him to U.A. tomorrow. Early morning, if you can."

"Understood."

All Might hung up, only to hear a groan from Izuku.

"All... Might?"

"Maybe I hit him a little too hard" He thought to himself as he walked over to the boy and picked him up and proceeded to the young hero's home as Midoriya snoozed away on All Mights's back.

Next day

The birds were out, and people were waking up to the start of their day. Izuku Midoriya also woke up, starting what could only be described as a strange day.

As he stared at the strange device latched onto his wrist, the events of the previous night replayed in his mind.

"Guess it wasn't a dream," Midoriya thought with curiosity, staring at the black-and-green device. He glanced around, making sure no one was watching him.

Pressing the two rings on the Omnitrix, it popped open, revealing a holographic figure of the flaming alien form from last night.

"Cool."

Izuku turned the dial and was surprised to see another alien form—this one had four arms and seemed to have immense strength. He kept turning the dial, discovering a silhouette of a jellyfish and continuing through the rest, finding a total of ten different forms within the watch.

"There's a total of ten forms, and based on yesterday, they probably each have unique abilities," he muttered to himself.

Midoriya got out of bed, grabbed his phone, and found a message from All Might.

'Young Midoriya, please come to U.A. at your earliest convenience. We need to discuss the matter of the strange device. Make sure you arrive by 10:30.'

Checking the time, Midoriya's eyes widened—it was already 9:50!

"Crap!" he shouted, rushing to take a quick shower. After putting on clothes and grabbing his red shoes, he bolted out the door.

" Izuku, where are you going? You haven't had breakfast yet!" his mother called.

"Sorry, Mom! I have to meet with someone!" he shouted back, already sprinting down the street. As he ran, he checked the time again and realized he was going to be late.

"Crap! What am I going to do? I don't want to let All Might down!"

Just then, like a miracle, Kevin Levin, his best friend, pulled up in a green muscle car. Midoriya stopped in awe as Kevin grinned brightly.

"Woah! You actually fixed it?! You rebuilt it from the ground up!"

With a smug grin, Kevin nodded. "Yeah, I'm awesome. It took me two years, but all the hard work paid off. Even though I might not get into any high school, I've got a friend who's willing to give me a chance. Once I show them this high-powered baby, things will look up for me!"

Midoriya admired the car, feeling proud of Kevin's accomplishment. "It looks incredible. So, can I get a ride?"

"Yeah, wait... crap! Do you mind dropping me off at U.A.?"

Kevin raised an eyebrow. "U.A.? Why?"

"Please?!" Midoriya pleaded, clasping his hands together.

Kevin shrugged, thinking it was just one of Midoriya's odd requests. "Alright, hop in."

As they sped down the road, Midoriya held on tightly, looking panicked. "You know how to drive, right?!"

"Tch," Kevin smirked confidently. "Do I know how to drive?" he replied rhetorically, pushing the car to full speed as if to test it out.

Kevin seemed to be having the time of his life, but Midoriya looked like he was about to pass out. A few minutes later, Midoriya was foaming at the mouth, while Kevin burst into laughter.

"I thought I was going to die," Midoriya groaned.

"Oh, don't be a baby! A little thrill won't hurt ya! Now get out, I've got stuff to do!" Kevin said, still grinning.

Midoriya waved at his friend as he exited the car. Just then, a booming voice caught his attention.

"Young Midoriya, you arrived on time, just as I asked! Here, take this!" All Might called out, standing nearby with a serious look.

All Might handed Izuku a visitor pass, his eyes narrowing slightly as he glanced at Levin. "That was your friend Levin, wasn't it, Young Midoriya?"

Izuku nodded, his eyes fixed on the sleek green muscle car. "Yeah, he has an amazing Quirk – Osmosis. But he doesn't want to be a hero."

All Might's gaze lingered on Levin, a hint of suspicion in his eyes. He cleared his throat before turning back to Izuku. "Osmosis allows him to absorb anything. That's... quite a powerful ability."

Izuku's confusion deepened. "But what does it mean?"

All Might's expression turned serious, his voice low. "We'll discuss that later. For now, let's focus on your visit."

As they walked towards the UA building, All Might cast Levin a sidelong glance, his eyes clouded with concern.

Izuku, oblivious to the tension, marveled at the campus. "Incredible!"

All Might smiled, his demeanor lightening. "Hopefully, you'll become a student here soon. For now, let's head to the principal's office. We can't waste time."

A few hours later

Midoriya was subjected to hours of testing as the heroes scanned the watch and its connection to him. Recovery Girl had given him a full check-up, taking blood samples and other fluids.

Midoriya was feeling a mix of emotions—on one hand, he was ecstatic to meet two pro heroes, Power Loader and Recovery Girl, and even got their autographs. On the other hand, the tests were far from comfortable.

As Recovery Girl reviewed her notes and the data gathered, both she and Power Loader stood beside Midoriya.

"The device has completely fused with you," Recovery Girl said, her tone serious.

Midoriya looked confused and a bit worried. "Fused? You mean…?"

Power Loader chimed in, "While it looks like a watch, it's not just attached to your skin. It's latched onto your bones, your flesh, and has merged with your DNA."

Midoriya blinked in shock.

"So far, the device seems permanently attached to you," Recovery Girl added. "But it's also increased your healing abilities. Your body has changed, too—your stamina and all your physical capabilities have improved."

All Might, who had been quietly observing, asked, "How much would you say the boy has changed?"

"Hmm... He'll still need to train physically," Recovery Girl said, "but in about four months, he could reach what we consider peak human condition—or at least peak human condition for someone his age."

'Four months?"!' All Might thought to himself, surprised. 'With that, I could give him One For All much sooner than I originally planned.'

...

"Now, if all the tests are complete, I'd like to test the boy in his alien forms, if you don't mind?" A new voice spoke from the doorway. Izuku turned and saw a dog, bear, and mouse hybrid figure that he immediately recognized.

"Principal Nezu?!"

"And you must be Izuku Midoriya. It's an honor to meet you," Nezu said with a smile. "Toshinori, I'd like to speak with you in private."

All Might nodded as Nezu led him out. Before leaving, the principal turned back to Midoriya.

"Oh, and please meet us in the training room afterward. We'll be testing the Omnitrix."

Midoriya blinked in confusion. "Omnitrix?"

Nezu paused for a second, realizing his slip-up, but then smiled. "Well, that nifty watch of yours should have a name, don't you think?"

Midoriya nodded, not questioning one of the smartest beings on the planet. "R-Right!"

Nezu and All Might headed to the principal's office. When All Might entered, he noticed a man sitting inside, looking as though he desperately needed coffee. The man had long black hair and wore a scarf. All Might recognized him instantly.

"Aizawa," All Might said.

"Oh, it's you," Aizawa replied in a bored tone. "I thought this was a meeting for actual plumbers."

All Might immediately became defensive. "Hey, I may not be an official Plumber, but I've helped out in the past. And, by the way, I thought all the Plumbers retired five years ago."

Aizawa shrugged. "Yeah, they did. When Hisashi took down Vilgax, the alien threats dried up. But I've been hearing rumors that Vilgax is back. For Hisashi's family's sake, I hope it's not true."

Nezu, seated at his desk, poured himself a cup of tea. "That's exactly why we're here. Thirteen and the others couldn't make it—Phil's... off doing his own thing."

He took a sip before continuing, "I've heard the same rumors about Vilgax's return. What makes things worse is that the Omnitrix is on Earth."

Aizawa, who usually kept a neutral expression, looked shocked for a brief moment. "It's on Earth?! We need to track it down—if it falls into the wrong hands—"

Nezu interrupted. "All Might has already located it. The Omnitrix is attached to one Izuku Midoriya."

Aizawa's mouth went dry. "Midoriya? His son?"

Nezu nodded.

Aizawa quickly responded, "We need to put the kid under protection, we need to—"

"We won't be doing anything for now. I want to test the boy first. We'll observe his actions and then plan how to proceed," Nezu stated calmly.

The pros nodded in agreement.

All Might spoke up, "Speaking of which, should we tell the boy about... all of this? The Plumbers, the aliens, everything his father did?"

"No," came the immediate response from both Nezu and Aizawa. All Might looked surprised.

"What? Why not?"

Nezu fixed him with a serious look. "You want to tell the boy that his father didn't die in a car accident, but was murdered? That the same being who killed his father is coming to Earth for the device on his wrist? And that if he doesn't defeat this being, the entire world could be destroyed? You want to put that kind of responsibility on him?"

All Might remained silent, processing Nezu's words.

"We'll inform the boy when the time is right," Nezu continued. "But right now, it's far too risky. He'd panic, and that's the last thing we want."

With that, Nezu clapped his hands together, his smile returning. "Now, let's see if this boy lives up to his father."

After getting changed, Izuku exited the room and followed Power Loader to a massive gym. As they entered, Izuku noticed how vast and enclosed the space was—completely empty, perfect for a demonstration. Waiting for him were several pro heroes: Midnight, Cementoss, Aizawa, All Might, and Nezu.

Izuku, feeling the weight of their presence, bowed deeply in respect. "I-It's an honor to meet you all!"

Midnight chuckled. "Oh, you're quite energetic, aren't you?"

"Greetings, young man," Cementoss added with a nod.

Aizawa, less enthused, sighed. "Let's just get this over with."

Nezu, ever composed, turned to Izuku. "Now, Midoriya, if you could activate your quirk?"

Izuku swallowed hard, nerves gripping him. He was about to show them the Omnitrix for the first time. With trembling hands, he pressed the Omnitrix, a holographic figure appearing from the dial. He cycled through the forms before slamming down on the device. A bright green flash exploded in the room, forcing everyone to shield their eyes.

When the light faded, Izuku was gone.

In his place stood a new alien form, blue-furred and muscular.

"Hey, hey, where did the kid go?" Present Mic asked, looking around in confusion.

Midoriya, now the alien, examined himself with wide eyes, curious about the blue fur covering his body.

"Aw, I was hoping for the fire guy," the alien muttered in slight disappointment, his voice deep and unfamiliar.

"You're still learning to control these forms, correct?"Nezu inquired, observing him closely.

The alien nodded. "Yeah, these powers just showed up yesterday. I'm not sure what they all do yet."

"Interesting,"Nezu mused." Why don't you try running? See how fast you can go."

The word "run" seemed to trigger something deep within the alien. His instincts screamed at him, pushing him into a runner's stance before he could think. Then, without warning, he took off.

The effect was immediate.

A massive gust of wind blasted through the gym, strong enough that Midnight struggled to keep her glasses on. Present Mic's jaw dropped, and his sunglasses shattered as they hit the floor. Clothes were ruffled, hair was blown askew, and several items were knocked over by the force of Izuku's speed.

Izuku had become a blur—a blue blur racing through the room at incredible speed. Even All Might couldn't keep up with the alien's movements, as Midoriya zipped from one side of the gym to the other, leaving only a whirlwind in his wake.

When he finally came to a stop, his momentum carried him a bit too far. Not used to his newfound speed, he stumbled and crashed into the wall with a loud thud. Despite the impact, he managed to say,

"Woah," his eyes wide with amazement at the sheer power he had just experienced.

The gym was dead silent as the teachers stared, their expressions a mix of shock and amusement. Midoriya looked around sheepishly, taking in the chaos he had caused: teachers with ruffled hair, misplaced glasses, and slightly disheveled clothing.

The boy immediately bowed in and apologized. " I'm so sorry! I'm so sorry!"

...

The teachers quickly ruffled their hair back to normal.

"Don't worry, kid. Your speed is truly something. I could barely track you moving that fast," All Might said, a grin on his face.

"Indeed, young man, your speed is remarkable," Cementoss agreed, nodding.

"That kind of speed may be a displeasure to most women," Midnight added with a teasing tone.

"Midnight," All Might and Aizawa warned in unison. "We talked about this," All Might continued.

"Hey, he's not my student, so I have free rein," she retorted defensively.

Midoriya turned red with embarrassment as Nezu spoke up. "So, Mr. Midoriya, there are 12 flying drones. I want to see what you can do. Try your best to disable them. You will have a minimum of 5 minutes."

"Hey, whoa! Isn't that a little too much for the boy?" All Might interjected with concern.

"All Might, you know what's out there. We shouldn't coddle the boy, should we?"!" Nezu replied.

All Might glanced at the principal before turning to his pupil. "! "Only if he agrees to it. Young Midoriya?"

Izuku gave an unsure nod, clearly nervous. As the 12 drones flew from the ground and began to surround him, the teachers stepped back, watching in concern.

The alien gulped, the beeping of the drones filling the room as the countdown began. As the drones activated, they immediately started firing. Izuku's legs trembled, fear evident on his face. He had never been in a fight before; Kevin usually handled everything for him. Even when Izuku tried to help, he often ended up beaten with a single punch.

As the alien braced himself for impact, preparing to be shot down like a trapped animal, he suddenly realized that the bullets hadn't hit him yet. He opened his eyes to see them approaching in slow motion.

"Hey, they're moving so slowly!" he exclaimed, momentarily surprised.

But despite this realization, his legs still shook uncontrollably, paralyzing him with fear. He was terrified.

'Even though I have a quirk, I'm still this weak, quirkless wimp! I can dodge bullets, but I'm just standing here?! Why?!'

Memories of being put down flooded his mind—how everyone had called him "Deku," how they labeled him weak, wimp, and other hurtful names that chipped away at his already fragile pride and self-confidence.

As he teetered on the verge of giving up, a few words echoed in his mind, a sentence from the man himself: "You too can be a hero."

Izuku opened his eyes, and they glowed green like emeralds. Suddenly, he blasted off like a bullet, dodging the barrage of attacks aimed at his previous location. The teachers watched in awe as Izuku faced the 12 drones, which began firing relentlessly.

With incredible agility, Izuku dodged every attack, leaping off walls and backflipping to avoid the hail of bullets. Not a single shot grazed him.

The teachers were stunned, but Aizawa and Nezu wore disappointed expressions.

"He's only dodging," Aizawa said, his voice tinged with disappointment. "As fast as he is, he's merely evading attacks. Time's running out."

Nezu checked the timer: 2 minutes and 50 seconds remained.

Determined to test Izuku's limits, the principal increased the drones' firepower, equipping them with missiles.

"Are you just going to keep running?" Aizawa asked, his eye glowing with intensity, his floating scarf billowing.

"For 3 minutes and 10 seconds, you've been running and dodging. Nezu gave you 5 minutes to take down these drones, and you've wasted over half that time."

The teachers' words cut deep.

"All Might says you're special, but I think you're just a kid with too much power and no potential," Aizawa said, frustration etched on his face. "You can't become a hero, Midoriya."

A missile launched, catching Izuku off guard. He stumbled backward as the blast hit the ground.

The harsh words stung, and Izuku struggled to get back up. Everyone saw his struggle.

Aizawa turned away, dismissing Izuku as a waste of time.

But then...

"No..." Izuku panted, standing up, his resolve etched on his face.

Aizawa halted, his gaze snapping back to Izuku.

"I do have potential. I will be a hero!" the alien shouted with passion and fiery spirit, his words resonating with those around him, reminding them of a familiar pro hero and an old friend.

The speedster stood up as the missiles armed themselves. He wiped some blood from his cheek, and everyone watched in confusion.

"Why isn't he running away?" Midnight asked, concerned.

Even All Might looked ready to step in. "Kid, run away!"

As the drones closed in and launched their missiles, instead of fleeing, the boy crouched into a running pose. With a sudden blast, he took off with a sonic boom, causing everyone to cover their ears. He charged towards the missile, leaped into the air, grabbed it, and threw it back toward the drone, destroying it in an explosion.

Everyone watched in awe as the boy faced the remaining drones. Without hesitation, he sprinted at top speed, grabbing another drone and using it as both a shield and a weapon. As two more drones opened rapid fire, he dashed forward, using the captured drone to block the bullets. He rammed into them at full force, leaping onto one drone before slamming it into another, destroying both with precision.

The speedster didn't stop for a second. More bullets came from a nearby drone, but he used the damaged drone as a shield again. Two other drones approached from opposite sides, both ready to gun him down. Acting quickly, the boy threw the broken drone like a frisbee at the drone ahead of him, then backflipped out of the way just as the two remaining drones shot each other down.

Breathing heavily, the boy saw there were four drones left.

"C'mon, Izuku! Think! I've studied every hero, especially those with speed quirks! I need to figure this out, I need to..."

"Am I fast enough? Only one way to find out!" the boy shouted, determination surging through him.

Izuku bolted forward, rapidly closing the distance between him and the drones. As he picked up speed, a powerful current of wind formed in his wake. Faster and faster he ran, forcing the drones together. The sheer velocity began pulling them into each other as they smashed and collided. The boy pushed even harder, his speed creating a swirling vortex, the force of which kicked up dust and debris, forcing the teachers to shield themselves.

The windstorm caused by his speed roared through the room, making it nearly impossible to see anything clearly.

Finally, Izuku stopped, stumbling slightly as dizziness overtook him. As he came to a halt, the remains of the drones clattered to the ground like coins being dropped, their destruction complete.

A loud beeping came from the Omnitrix, and a flash of green light engulfed the alien form, returning Izuku to his human self. The boy collapsed to the ground, breathing heavily, but he managed to push himself back to his feet.

Nezu clicked the stopwatch, glancing down with a smile. "50 seconds remaining."

"This kid," Aizawa muttered, a rare grin spreading across his face.

"Young Midoriya… when did he get so cool?!" All Might thought, astonished.

Izuku, still feeling dizzy, asked, "How did I do?"

"Excellent," Nezu said, smiling brightly. "And with time to spare."

The small mammal then turned to All Might. "Now then, young Midoriya, since the device is stuck to your wrist, All Might, it will be your responsibility to teach the boy."

Everyone's eyes widened in surprise.

"You'll have plenty of time," Nezu continued. "Think of this as a testing ground. How you train young Midoriya over the next seven months will determine the results during the exams."

Aizawa nodded. "Seems logical. We won't have much time because of our responsibilities, but All Might, considering your injury and everything, you'll have plenty of free time."

Midnight chimed in, "Didn't you expel your whole class, Aizawa?"

Midoriya's eyes widened in terror. "He expelled his whole class?!"

Aizawa shrugged. "I still have my duties as a teacher, like the rest of you. And I'm a pro hero; I've got other stuff to handle, too," he said. Then, with a grin, he added, "Besides, if the kid fails, it'll reflect on All Might as a teacher. Wouldn't want a teacher with such incompetence working here, would we?"

All Might, however, remained calm. "I can assure you that young Midoriya will pass the entrance exam with flying colors! But until then, I'll need to help him learn fast. The UA entrance exam is in seven months, so we need to prepare."

One of the Plumbers in the room added ominously, "And prepare for what's coming. Vilgax."

Midoriya gave a nervous smile before suddenly realizing something. "Hey, I turned back to normal!"

"You seem surprised," Cementoss remarked.

"Well, yesterday I stayed in alien form for like an hour, until All Might knocked me out," Izuku admitted.

"HE DID WHAT?!" Everyone turned to All Might, who was fidgeting awkwardly, his fingers pressed together guiltily.

"It was the only solution we could think of! We couldn't let him show up at home as a giant bonfire," All Might said defensively.

"And your first thought was to knock him out?" Aizawa asked, visibly annoyed.

Nezu, his aura suddenly menacing, added, "Please find a better method of turning back to human form that doesn't involve All Might knocking you out."

Both All Might and Midoriya shivered. "Y-Yes, sir," they stammered in unison.

Midoriya then perked up, sounding excited. "But this confirms something important! Each transformation seems to be linked to me. If I'm unwell, the transformation is too. If I'm fatigued, I revert back to human."

...

As the day came to a close, Midoriya and All Might stood on the beach, wrapping up their training session. Midoriya had noticed that moving the trash had become much easier—his stamina, strength, and speed had all noticeably improved.

"Alright, young Midoriya, that's enough for today," All Might said, wiping some sweat off his brow. "Now, we should focus on figuring out how you can transform back. Do you know any quirk users who specialize in transformation?"

Midoriya hesitated before answering. "Not really..." he said, but it wasn't entirely true. "I do know a few people in my class, but they want nothing to do with me."

All Might thought for a moment. "Have you tried tapping the faceplate when you're transformed?"

"That's literally the first thing I tried!" Midoriya replied with frustration.

"Well, until we figure it out, it might be best to avoid transforming unless necessary. You definitely don't want your mother to find you in the form of, uh, Heatblast!"

"Heatblast?" Midoriya raised an eyebrow.

"Yes, your fire transformation. You should give them names to help distinguish between them."

"That...makes sense, I guess," Midoriya nodded.

All Might continued, "Tomorrow, let's start categorizing all of your transformations and testing their abilities, alright?"

Midoriya nodded eagerly, a bright smile spreading across his face. For some reason, a phrase suddenly came to him—a cosmic, powerful feeling that felt both unfamiliar and strangely fitting.

"It's hero time!"
