Chapter 1: Legendary

-Planet Vegeta, Deep Space-

On the home of the Saiyans: Planet Vegeta—named after a line of kings that took the same name—there existed a nursery full of incubation pods where many infants resided. In one such pod, there was a green haired infant with freckles on his darker tanned face, he currently slept within the incubator in a sort of homeostasis.

The pod he was in was also green and his Saiyan tail flicked around unconsciously, it's tail muscles showing through with every movement. This was Broly, the son of the Saiyan scientist Paragus.

Outside his pod, there were several scientists with the king himself, who was looking at his son's pod in pride.

"Ah, my son, one day you'll grow into a ferocious king, I'm sure of it." The man said before he noticed the green pod. "Who's son is this?" He questioned.

"His name is Broly, the son of Commander Paragus, sire. We have him here because… well." One of the scientists said.

"To put it bluntly, your majesty, his power level was well over nine thousand." A female Saiyan states. "Possibly even ten thousand, given our best estimates." She added, looking at the child.

"What is he doing in this chamber?! This is supposed to be reserved for potential assets!" King Vegeta yelled.

"Oh but young Broly could very well be an asset. In fact some of us have suspicions that he may be the… legendary super Saiyan." The third scientist said. This caused the leader of the Saiyans to stiffen.

"... I want him sent to planet Vampa." He growled.

"... Your majesty?" The first said.

"Do it. Now." The King states angrily as he walked away, his cape swishing dramatically.

(Later)

The infant Broly's pod was stuck in a ship and sent to the planet Vampa, with his father following. However, fate is rarely so predictable…

On the way to Vampa, Broly's pod collided with an asteroid and knocked it off course while destroying the on-board tracker. Paragus would never realize this as he continued to Vampa and found no trace of his son. Broly, meanwhile, would find his way to a far better world. One where he would grow into a strong fighter… A hero.

(Timeskip)

Fast forward about four years after the infant Saiyan's pod crash landed on Earth in the country of Japan and the boy was then adopted by the childless couple of Inko and Hisashi Midoriya.

In this world, everyone had superpowers known as quirks that showed up at around age four or five in the cases of late bloomers. Eighty percent of the population was superpowered, twenty percent was not.

And from the moment that the young Broly—renamed Izuku Midoriya by his new family—reached the age of four, it was clear that he was very abnormal. Even by this world's standards of the word.

First was his metabolism. The amount of food he ate was insane and hard to keep up with. To compensate, the boy's mother started up a garden so they could keep themselves supplied without much of a hassle.

Second was the tail stump that they found on him. Apparently he had a simion tail before arriving to earth that was removed and cauterized, thus preventing it from being able to grow back. The two assumed this body part was like the top knot of a samurai, and the removal of which meant that he was an outcast.

Third was his abnormal strength, stamina and overall heartiness and durability. All were at superhuman levels and as far as they knew, he didn't have a quirk. Additionally he also possessed great intelligence as well, as well as a less than beneficial temper.

Put simply, if Izuku was angry enough, he could likely shatter a mountain into rubble. Though luckily for most, he had a very gentle touch to him when he's calm, making him so approachable that wildlife would flock to him and bask in his presence.

Though he also had something else on his side, the boy also had the ability to use his life force—or Ki—as a sort of weapon or asset. Allowing him to enhance his physicality, create energy attacks, and even fly to a lesser extent.

This ability made it seem like he had a quirk, but with a lack of an actual quirk factor, many doctors still decided to classify him as quirkless. Though this did little to dampen the young boy's spirits about becoming a hero, since he already knew that he was strong on his own.

Currently, Izuku was in the woods alone with two deer fawns that he fed regularly, petting the two animals as they came up close to him. The boy smiled as he petted them, but his moment of peace was ruined when Katsuki Bakugo along with his lackeys suddenly assisted and scared them off. They laughed while Izuku looked angry.

He knew Bakugo from his grade school, but he never talked to him, or anyone else for that matter. As he seemed to learn that dealing with people led to annoyance, annoyances led to anger, and anger—at least in his case—led to things getting destroyed.

Katsuki smirked as he punched his palm, causing a small explosion. "Hey! Izuku Midoriya, right? This your hangout spot?" The blonde questioned as the boy glared at him and got up, showing that he was at least two or three heads taller than the explosion user.

"Yes, and you scared my friends away." The green haired boy replied as his Ki powered up. "You're making me angry, Katsuki. You won't like me when I'm angry." Izuku growled. The Pomeranian just grinned.

"Show me." He challenged. Glancing at a tree, he walked over to it, grabbed it… and ripped it out of the ground before he crushed it… with one hand. The display was intended to intimidate the blonde, but it just made his smirk widen into a full on smile. "Now we're talking!" The boy said as he and his cronies charged at Izuku, clashing with him.

(Later)

After half an hour of cutting loose on each other, Katsuki and Izuku finished out the fight by slamming their heads together over and over again, causing small shockwaves until the last collision sent them flying into two trees, making them collapse in exhaustion. Covered in various injuries.

"Head… Hurts." The Saiyan groaned.

"Oh, mom's gonna… kill me…" Katsuki groaned as he held his throbbing head. If he didn't get CTE from this fight, it would be astonishing.

His lackies were also out cold in the decimated forest, and as the kids laid there, the two fawns from before walked up to the two and started licking their cheeks.

Izuku looked at them and smiled slightly. "Good deer." He smiled warmly, stroking its head.

(Timeskip)

Twelve years later, the same boy was now walking to school at age sixteen. His body now much more muscular than when he was a kid, his hair was a bit longer and he also was now a staggering six foot eleven inches, pushing an even seven feet. He was a very large kid and he was still growing. As he walked, the sound of commotion caught his attention, causing him to look up and see that a giant villain was attacking the train station.

"How many times have villains stopped the commute this month?" A person asked.

"Seventh, I think." Another replied.

"Oh joy…" Izuku groaned as he looked around. Pulling out a notebook he had with him, he decided to analyze what he was seeing.

As he looked around, he saw Death Arms keeping debris from hitting civilians while Backdraft made a water barrier to keep the onlookers back. Kamui Woods, meanwhile, was taking on the villain in question. Izuku watched as he leapt around the larger foe's attacks before getting his finishing move ready.

"Can't really say that I think that's gonna work…" The Saiyan said as the hero made his move, only for a massive woman to come crashing out of nowhere with a flying kick to the villain's side.

"No need to worry about this bum anymore, boys!" The woman said with a smile, causing Izuku to facepalm.

"I'm just gonna go ahead to school." He said in exasperation before walking off. As he reached his classroom, he soon fell victim to the door frame—which was not tall enough for him—causing himself to hit his head on said frame. This was something of a regular occurrence with the boy. "Ow…" The Saiyan said flatly.

A few people chuckled lightly, but he didn't pay them any mind as he sat down at his desk. "You really gotta learn to duck, man." One of the kids in his class who hung out with him and Katsuki on occasion said.

"Tried already. It's too difficult." The gentle giant stated. He wasn't wrong, every time he tried to duck before he hid the frame, he got a crick in his neck.

"Oh. Right." The same kid remembered.

"Alright, settle down kids!" Their teacher exclaimed as class began. "Now, as third year students it's important to start thinking of your futures and what you want to do with your lives." He continued, taking a stack of papers. "Now, I could pass out these career aptitude tests. But why bother?" He continued before tossing the papers into the air. "I know all of you want to join the hero track!" The man added.

Everyone started cheering, their quirks on full display. Izuku just sat at his desk with a bored expression. Katsuki, meanwhile, scoffed.

"Yes yes, you all have powerful quirks, but no power use in class!" The teacher stated.

"Oi! Don't lump me with the rest of these extras! I'm the real deal but these guys will probably only get jobs as sidekicks to some busted D-lister, ha!" He yelled, causing the other students to yell at him.

"Ah yes, Katsuki Bakugo. You're applying to UA, right?" The teacher noted. "You've got impressive test results, maybe you will get into UA." He added.

"He's going to try for the National School?" A girl asked.

"But it's next to impossible to get in there!" Another kid added.

"That's why it's the only place worthy of me. I aced all the mock tests and I have the best chance of getting in." The blonde stated. "I'll end up more popular than All Might himself, and be the richest hero of all time! The whole world will know my name, and it all starts with U.A. High!" He added proudly as he hopped on his desk.

"Oh, Midoriya. I see you're applying to UA too." The teacher noted, causing Bakugo to go rigid.

"I am. I hope there's no problem with that." Izuku nodded calmly. This caused everyone to look at him nervously.

"You sure that's a good idea? I mean you're strong as hell but it's not like they'd accept someone without a quirk." One kid said.

"Actually that rule's been removed so it's fair game. Plus I've been training constantly, so I should be able to at least get a passing grade." The Saiyan stated.

"You think you can beat me, Deku?!" Katsuki yelled at the boy, who didn't even react.

"I never said that, Kacchan. I don't have any intention of competing with you, so I honestly don't see the problem." Izuku stated calmly, but his grip on his pencil subconsciously tightened.

"You think UA is gonna accept a quirkless giant like you?! You don't even like fighting people!" The red eyed boy scoffed. "Face it, Deku! You don't have what it takes to-!" He started to bellow before Izuku's pencil snapped, cutting him off. The tall boy then stood up, towering over him while he looked down straight into his eyes.

"I may not like fighting people, but I am willing to cast that aside to defend the innocent if need be." Izuku stated calmly. "If I am to become a hero, I must learn to do such things. Is that a problem, little Katsuki?" He questioned with a firm tone that seemed hard as stone. The rest of the class was shocked at how blatantly charismatic the gentle giant was right now. It was like he had become a whole other person.

As the two stared each other down, the Pomeranian let out a tsk as he looked to the side. "Whatever. If you wanna make yourself my rival, then fine. Just don't get in my way." He retorted.

"I think that's the most level headed thing you've said all day." The green haired boy said, his softer demeanor returning as if nothing ever happened. Which made Katsuki roll his eyes as they both sat down.

"Whatever." He sighed as their class continued.

(Later)

As Izuku was packing up his backpack to head home after school, Katsuki walked up to him and waved a slip of paper in his face.

"What's that?" Izuku asked as he looked at the paper.

"A ticket to the gym I go to. If you're gonna be my rival, I want you to train like I do." The exploder explained.

"Why? Maybe the way you train doesn't work for me." The boy retorted, only for the blonde to give it to him.

"Just take it, ya damn nerd." Katsuki states. "I go there every Thursday, Friday and Saturday. Be there, or be square." He added as he walked away.

'Hm… Well, even if it doesn't work for me, it is nice to have options.' Izuku mused as he pocketed the ticket before beginning his walk home.

As he walked, he continued to look through his notebook to drum up ideas for special moves, but was pulled from his thoughts as he felt someone bump into him.

"Oof! Sorry about… that." A female voice apologized before becoming slightly surprised, causing Izuku to look up from his notebook and see two girls in front of him. One was a brunette with a perma-blush on her cheeks with a cute round face and an attractive figure.

The other was a blond girl with two messy hair buns, cat-like yellow eyes and actual fangs. She also happened to have an equally attractive figure, and she was also the one who hastened to apologize to him. As she looked up at him, she accidentally fell backwards in surprise.

As soon as this happened, the boy's instinctual desire to help kicked in. So he quickly knelt down and held out his hand to her.

"Are you okay?" He asked her softly.

"Uh, yeah. I'm fine." The blondie replied as she accepted the offered hand—which completely pulled her petite hand in—and was pulled to her feet. "Who are you?" She asked as she looked up at him.

"Izuku Midoriya." The Saiyan replied. "And you two?" He asked.

"Ochako Uraraka." The brunette replied.

"Himiko Toga." The cat-like blondie added. Both girls were also blushing a bit, particularly because of how muscular the boy was.

'Oh my god, those neck muscles look like they could cut diamonds!' They thought in unison, while also wondering how his uniform was able to contain such a physique.

"Are you two heading to the train station?" The gentle giant asked.

"Uh, yeah, we were just headed there." Himiko nodded.

"Do you know where we need to turn to get there?" Ochako asked.

"You just need to head south and take a right turn before making a left and heading straight from there. The train station will be two blocks away after that." The giant replied.

"Thanks." Ochako said before grabbing Himiko's arm. "Come on Himiko! We're gonna miss the train!" She said.

"Hang on." The blonde said before she took a pen and wrote something on Izuku's hand. "Here are our numbers. Give us a call sometime when you're free, Okay big guy?" She told him with a smile.

"Um… Okay?" Izuku responded in minor confusion as he looked at the numbers written on his hand while the girls made their way to the train station. The boy scratched his head as he walked home.

He never really was popular with the ladies when he was little or now. Not to say they didn't find him attractive—far from it—it's just that most preferred not to date him because his imposing size scared them, or it was because his gentle nature made him seem too pure to be dated just yet.

So for him to get two numbers from a pair of girls like this, it was definitely a good confidence booster for him. 'This is… new to me.' He mused inwardly, though his musings were soon interrupted when he passed under a bridge and a slime villain popped out of the sewers behind him.

"A meatsuit. Perfect timing." He gurgled as he grabbed the Saiyan, only for him to flare his Ki and force him back. "What the-!" He exclaimed in shock.

"You almost got slime on my uniform." Izuku stated, attempting to keep his voice level as his ki flared. "That makes me angry, you shouldn't make me angry." He continued as his ki turned green. "You wouldn't like me when I'm angry." He added.

"You think that scares me?! I'll overtake you and make you my meatsuit! I still gotta escape!" The sludge villain exclaimed. It was at that moment, the manhole cover was knocked off of its position, causing both to look at it.

"It's alright, everything's fine." A deep voice said. "Now that I'm here that is." The figure who spoke added, and as soon as he saw the man, Izuku instantly recognized him.

"All Might." He uttered in amazement.

"No… not now…!" The sludge man uttered in fear.

"Texas SMASH!" The hero yelled as he reared his fist back and threw it forward, sending a wave of pure force at the sludge villain and scattering his body everywhere. Izuku managed to hold his ground and avoid getting knocked off his feet, albeit with a small amount of effort.

Though the ordeal did leave the boy a bit dizzy as he tried to get his footing back while All Might gathered up the villain in a soda bottle. "Whoa… Dizzy." The boy groaned as he fell on his backside.

(A few minutes later)

Izuku's eyes blinked open as he felt someone lightly slapping his face. Looking up, he saw All Might trying to wake him up.

"Hey, wake up, young man." He said as he kept delivering light slaps.

"Ngh, okay, I'm awake. You can stop now." The Saiyan groaned as he got up.

"Thought we lost you there! Sorry about that, I didn't mean to get you caught up in my justicing." All Might told him. "Usually I'm much more careful, but as it turns out this city's sewer system is pretty difficult to navigate! Ha ha ha ha!" He added with an awkward laugh.

"Right…" Izuku said flatly before taking out his notebook. "Anyway, could you-" He started to ask as he opened his notebook and saw that it had already been signed. "... Well okay, then." He said with a blink.

"If you don't mind my asking, Young Man, What is your quirk exactly? It looked like an augmentation type from where I was standing." The man asked.

"Technically speaking, I'm quirkless." The boy replied, causing the Symbol of Peace to do a double take.

"Then what was that you did?!" He asked in disbelief.

"To be honest, I have no concrete answer. I've had this power for as long as I can remember. Its origins are unknown to me." Izuku explained. "Though I do have a theory, or two… but I won't bore you with the details." He added.

All Might seemed taken aback by this and seemed lost in thought, before something pulled him out of it. 'That can wait, for now I need to go. I'm running out of time!' He thought before he quickly said goodbye and jumped away.

Izuku watched him leave and remembered something important. "Crap! I forgot to ask him that!" He said before he used his Ki and leapt into the air after him.

All Might, hearing something behind him, turned and was shocked when he saw Izuku straight up flying!

"Okay, now that's just ridiculous!" He exclaimed over the winds.

"I'm sorry for inconveniencing you, but I really need to ask you something important!" The Saiyan exclaimed over the winds as he flew.

"Can it at least wait until we've landed?!" The man questioned.

"Of course! I'm determined, not crazy!" The boy called back as the two landed on a roof and the Saiyan doing a bit of a tuck and roll. "Well, that was better than last time." He shrugged as he dusted himself off.

"I'm sorry, 'last time'?" All Might questioned with a raised eyebrow.

"Crashed in my neighbor's house, glass went everywhere, had to help fix it. And it took me weeks to get all the glass out of my skin." Izuku explained.

"... Okaaaay… What did you wanna ask me?" The No. 1 Hero asked awkwardly, trying to move things along.

"I've been gifted with great strength and power since birth, but I never developed a quirk. But I also know that in the world of heroes, there will probably be villains out there who are stronger than I am even with this strength at my disposal." The Saiyan explained. "So, All Might, I want to know…" He continued as the hero's body began smoking unbeknownst to him. "Do you think it would be possible for me to become a hero with my strength alone?" He asked.

'Dammit… Not now…!' All Might thought as his form was consumed by smoke. Izuku turned and blinked upon seeing the smoke, but when it cleared and revealed a skeletal man in the hero's place, he was equal parts shocked and confused.

"Um… What?" Was all the gentle giant could say.

"Most people would be shocked by what they just saw." The lanky man commented.

"Confused is more like it." Izuku clarified.

"Fair enough. But yeah, this is what I really look like. You know those fat guys at the pool who pretend to be buff? I'm like that." The skinny hero explained.

"How did this happen?" The Saiyan questioned. He got an answer in the form of a very nasty looking scar on the hero's torso.

"... How?" The boy questioned as he sat down, a mixture of shock and slight anger making him do so.

"A fight I had five years back. My lungs were basically destroyed, and my stomach had a huge hole in it. The surgery to fix it made it where I can't eat as much. Hence my appearance." He explained.

"Was it Toxic Chainsaw? Or some other guy?" The kid asked.

"You certainly know your stuff, but no. He got a few hits in, but none of them did this to me." All Might explained with a shake of his head. "No, this was from an even more intense fight. This one had to be kept under wraps so no one would know the Symbol of Peace was so badly injured." He continued.

'Who could possibly be strong enough to do this to All Might?' Izuku thought, his eyes narrowed. "Right…" He nodded.

"You sure are quiet, aren't ya kid?" The man said. "But to answer your question. To be honest, I don't really have an answer for you. I'm sorry." He continued. "I think it's just something you'll have to find out for yourself."

Izuku seemed to take this in for a few seconds before looking down at his shoes. "Oh." Was all he could muster. He couldn't put his finger on why, but for some reason he thought All Might would have an answer for him. Apparently he was wrong.

"That being said." The hero nodded once more. "I think that you should be grateful that you have such a strong body, despite being quirkless. Who knows? Maybe you could become a hero." He added as the two of them parted ways to head to their respective destinations. Leaving Izuku with a lot of thinking to do.

'Even though I didn't get a definitive answer, I'd say today wasn't a total loss. He did say it could be possible.' Izuku thought as he jumped away.

'Note to self though, keep that kid in mind as a candidate for One for All.' All Might thought as he walked down some stairs, before noticing that the bottle containing the sludge villain was gone. "Oh no…" He gasped.

(Elsewhere)

Meanwhile in another part of town, Himiko and Ochako were walking to the same train station that Izuku was at that morning. However as they continued to walk, the bottle containing the slime villain burst open and the creature started grabbing both girls.

"What the hell?!" Himiko shouted. Acting quick, she pushed her best friend away. "Ochako, sound the ala-!" She tried to say before being cut off.

"HIMIKO!" The girl screamed as her friend started to get swallowed by the slime, and she herself was still in its grip when her screams caught the attention of the nearby heroes.

As stated before, fate—it seems—is rarely predictable.

Dragon Emperor0: This story sure took a dark turn didn't it? A poor innocent girl just got swallowed by a slime monster straight out of a shitty hentai.

ThermalsniperN7: No shit. Anyway, welcome readers to our Dragon Ball-MHA story where Izuku is Broly.

Dragon Emperor0: This one's probably gonna be the oddest to write due to a few things that will be new territory for us. But I think it'll be fun. Also guys, should we have Class 1-A find the dragon balls? And if so, what should it be used for?

ThermalsniperN7: Let us know if you think this should actually happen. Anyway, see you next time!
