[PPGZ/MHA Crossover]

Musutafu, Dagobah beach

"Come on, Young Midoriya!" A muscular blonde commonly referred to as All Might (real name: Toshinori Yagi), the world's number one pro hero, shouted to a green haired teenager, Izuku Midoriya, hauling heavy boxes full of junk across the beach they were on. "If you want to be given this power then prove you are ready for it! Prove you are worthy and make your body ready!"

"Can't worthiness include a two-minute break?!" Izuku called out to his mentor, who just let out a loud boisterous laugh. The teen was wearing a simple blue T-shirt, red shoes and a pair of cargo shorts while the blonde was in his class green jeans and white shirt combo.

"NONSENSE! A true hero never rests, my boy! Ahaha!"

"I'm pretty sure that would actually be illegal in any other profession." The greenette grumbled, grabbing a gargantuan pile of garbage and going to drop it into the back of a nearby truck. "And I thought you said I was worthy anyways? Even if my body isn't ready."

"Ah, well what can I say, I really get into this whole motivation coach thing." All Might said with a chuckle, turning and pointing to a set of lockers nearby. "A true hero earns their powers by doing what is right with their own skills! Like you will earn your powers by clearing this beach of this unsightly trash. Come one now, we may still have three months to go but there is also still a lot of trash left! Those lockers won't move themselves across the beach, ahaha!"

"I'm going!" The teen grumbled, hurrying over as his face was lined with sweat. All Might smirked however, happy to see that while he was clearly working hard he wasn't overworking himself. 'Guess he gets the importance of not overdoing it now. Probably still has the bruises from that tumble he took.'

"Alright, keep at it, young Midoriya! Just remember, hard work is much nobler than natural talent even if neither are things to sneeze at, ahaha! After all, It's not like your powers are going to just fall out of the sky!"

When they both looked back on this day in future, they would both be unable to avoid laughing at how fate would slap the blonde across his smiling face.

For now though, he would just continue to laugh as he watched his successor trip over his own feet and hit the dirt… sand?

Either way, for the greenette it hurt and the blonde just laughed all the while.

Elsewhere, deep in space

"So… cold…."

In the inky void of infinite nothingness that was space, deep in it's coldest depths travelled six bright white lights, within them trapping several dark purple orbs slowly but surely shrinking and dissipating.

White and black Z-rays.

The black orbs glowed as a weak, once jovial but now just dying voice called out, no one able to hear it's cries.

"So…. Cold…. Have to…. Escape….."

They glowed brighter for a moment, as the black orbs radiated with a power only for the white lights around them to glow in turn.

"Last… chance…"

Suddenly, had sound been able to travel, all anyone in the nearby planets would of heard was a blood chilling shriek of fear, the orbs trying to push the white ones away violently.

Three white lights moved forward, and the purple ones became even more erratic and violent, as if scared.

A desperate attempt to survive. A futile attempt to keep on existing.

"POWER…PUFF BRATS…. LEAVE….. AHHHHHHHHHHH!"

The orbs exploded suddenly, the three white lights being blasted out along with a few much smaller black ones, hurtling across the cosmos and the remaining three white lights quickly smothered the majority of the black orbs, as they shrank before finally dissipating, leaving naught but the white orbs behind.

An ancient terror had died a pitiful death, and no one would even know.

However, he had not died without one final event set into motion. As the three white Z-rays and small black orbs hurtled further and further through space, a bright flash engulfed them all and they disappeared.

And reappeared in the same spot, yet still a different place, as they continued on a course towards a blue and green planet.

Earth.

Musutafu, Dagobah Beach, several hours later

"Haha! You look terrible, my boy." The skinny, almost skeletal secret form of All Might laughed as he walked alongside his successor, who was drenched head to toe in sweat and walking hunched over.

"I mean…. You kinda… turned up the training out of nowhere today. It's intense but… not this much usually." The boy said, with heavy sighs.

"You wouldn't have this issue if you hadn't overworked yourself, my boy." The blonde sighed, pulling out his phone and pulling up his contacts. He had a taxi service he kept on call for when he needed to return home after training the greenette.

"Says the man who's only all skinny right now because he pushed his muscle form for no reason while I was working my butt off." Izuku grumbled aloud, making the skinny man roll his eyes. It was rare to hear such comments from Midoriya usually but when he was tired his more sarcastic side had a tendency to come out. They reached the crossing in the road the two would usually part at, though this time the greenette stopped and smiled tiredly at something in the distance. "Man I miss being a kid, before powers started developing and that."

Following his gaze, Toshinori soon felt a small fond smile of his own grow on his face at the scene before them. Two children, presumably siblings where engaged in a water gun fight, playing on their little street corner and gardens.

It was quaint, wholesome and just a small joy in the world, children able to have fun. A nice scene to leave with positive thoughts… or at least that's what it would have been on any other day.

Because on any other day, Izuku's eyes wouldn't have turned skyward.

On any other day, there wouldn't be three bright white lights barrelling right towards the children, black beams separating off in other directions.

But what would happen on any other day just the same as that one, even as the blonde was rendered practically useless due to his power having been used up, Izuku didn't hesitate for even a second.

"YOUNG MIDORIYA!"

As the skinny pro reached out his hand his successor was already several steps ahead, launching himself forward at the girl about to be hit and shielding her with his body.

Toshinori's breathe hitched, heart constricting and eyes narrowing. For the briefest moment he feared the worst as he saw Izuku's body became completely coated in a pure white glow, his silhouette barely visible.

The little girl fell back, her brother pulling her away, toy lost somewhere. Then something unexpected happened.

After all, the number one pro had seen many, many things in his long career. He's be heartbroken but not surprised if the greenette has disintegrated, dying from the blast.

He wouldn't have been surprised if the teen teleported. Hell, even if he inexplicably started a perfect dance routine, he wouldn't have managed to surprise or shock All Might, as he knew to expect anything...

And yet, he couldn't expect this. In fact, what did shock him was something really rather simple in comparison to the other 'options' it could have been.

Izuku's feet landed on the ground, his body still moving and keeping All Might's satisfied his student was alive, but his glow turned from white to a light pink, then baby blue before settling on a brilliant emerald green.

The boy's form changed and to his surprise, a cry came from Izuku into the heavens themselves that at the time the blonde had no hope of understanding.

"BUTTERCUP!"

Finally, the light faded and the greenette came into view once more.

"H-huh? W-WHAT THE?!"

Toshinori hunched forward quietly, arms dropping forward as his jaw dropped and his entire being filled with endless confusion at what he was seeing.

If you asked Izuku what he'd been thinking when he jumped in front of that ray of light, the only answer would be nothing.

Well that wasn't entirely true, he was pretty sure the word 'protect' may have flashed by his mind as his arms had wrapped around the girl, a warm sensation hitting his back for just a moment.

Then, before he could even understand why, his body was moving on it's own at speeds he was fairly certain wasn't normally, everything around him gone into a green light he couldn't see past.

He felt a device in his hand and instinctively swiped at it, before he felt things around him start to change. His legs got colder, he felt something tight cling to his body. Fabric formed around him and hard solid lumps of metal felt as though they had formed on his wrists and ankles.

And then, a huge weight came into his hands that somehow, even despite his awareness of the objects weight, he was able to lift up with a single hand without a problem.

A cry escaped from his throat as an instinct he didn't understand.

"BUTTERCUP!"

And finally, the light faded away, the world coming back to normal. The very first thing he noticed is that his entire form felt… light. Much lighter than the human body had any right to be.

The second thing he noticed was that his clothes felt much different, so he looked down and his eyes widened in shock and confusion.

His outfit had changed completely. Instead of his red shoes he had one's that were green and solid metal, with massively oversized white soles making them look somewhat futuristic. His ankles and wrists had oversized metal bands with green, pink and blue trims.

His hands were now wearing fingerless gloves, the left of which also had three rings on his pointer, middle and ring finger, each with a light on top with the letter P visible inside them. They each also had the three colours, the green one on his ring finger lit up while the other two, pink on his middle finger and blue on his pointer finger, were dim.

Around his neck, he could feel the pressure of a solid black choker with another P engraved in it, though how he knew without seeing he wasn't quite sure. He also felt small white pearl earrings in his ears, despite the fact he'd never gotten piercings in his life. He even felt two diamond shaped hair clips in his hair.

Next came the parts that had him really confused. For reasons far beyond his comprehension, his old clothes had been replaced by what was essentially a tight green swimsuit, with the top having a large black trim and thin straps. Protecting his modesty at least was a long also green skirt with black trim. However, that also left the question, WHY THE HELL WAS HE IN A SKIRT?!

There was yet even more to this outfit however, as around his upper waist he felt a rather small varsity jacket of some type hugging his body. The collar and basque were both the same green as the rest of his new outfit, but with white lines circling around them, his rather tiny sleeves that only reached to his shoulders really were pure green and the main body was a light yellow colour that went well with the rest of the outfit. It also had a bright green P emblazoned on the left breast. Finally, there were two darker green lines that stretched around to the back and formed something of a heart shape, the inside of said shape completely white.

The final accessory completing the whole bizarre ensemble was a white belt with a tricolour detachable round communicator in the middle. It had three lights to the side, and several small gold accents around it.

"H-huh?! WHAT THE?!" He cried out in surprise, swinging around the massive item in his hand he didn't even realize he had. He turned, eyes wide and came face to face with his mentor. His face flushed red at the fact his mentor was seeing him in what was most definitely not an outfit meant for guys, but choose to focus more on the fact that it came out of nowhere. "A-All might? What's going on?!"

"Young Midoriya?! Is that really you?" The blonde asked, making the greenette tilt his head in confusion. "You look so different, If I didn't see it with my own two eyes I wouldn't even realize it was you! But… why are you in a skirt?!"

'My clothes changed, nothing else though? Also-' "Good question? I mean it was definitely whatever those white lights were at fault but… why this?! Why change clothe for one and why to this of all things?!"

"And there's also the question of the mallet." Toshinori added, confusing the greenette before his eyes turned to the item in his hand and his jaw dropped again. Somehow he was holding up what could only be described as a gigantic double sided mallet that had to hit harder most pro's could. Not to mention the… energy it was overflowing with. 'Wait, how did I ….'

"I… I don't get it." Izuku said with a confused sigh as he began moving forward. It felt easier than normal for some reason and he missed his mentor's stunned face, as he continued to move around in circles. "So that wasn't just someone with a clothes changing quirk playing a prank? It feels like more than that. Maybe I should go see a doctor-"

"Young Midoriya…. Come to me." All might commanded simply, voice serious and the greenette obeyed confused. "You absolutely, certainly, most definitely do not have a quirk right? No lies?"

"Yes! Why would I lie about that?!" The greenette exclaimed, raising a brow. The skinny man just pointed down and following his gaze, izuku's eyes widened once more. "O-oh… oh my god."

His feet weren't on the ground. He was hovering in the air… he was flying through the air! Confused, and wanting answers he focused on the idea of raising higher into the air and despite all the confusion, he couldn't help the smile that came onto his face as he raised higher into the sky.

"I CAN FLY?!" He asked excitedly, before looking around to the end of the street. "Can I fly fast?!"

"Wait, young man-"

It was too late though, Izuku blasted off into a blur of green light, quickly ending up at the end of the street and coming back in what felt like no time.

It also didn't escape Toshinori's notice that the greenette seemed rejuvenated entirely, somehow nowhere near as tired looking as before.

"MIDORIYA!" All Might shouted, quickly bringing his student's attention back to him, sheepish look on the greenette's face. "Focus please! We have no idea what has just occurred and if it's dangerous or just some oddly done prank to put you in a skirt…"

"Oh god, I forgot about that." Izuku's face quickly went back to being a blushing mess as he remembered, making the blonde raise a brow.

"How did you forget?"

"I found out I could fly. Kinda distracting."

"…Fair point." The number one pro conceded, taking a moment to try to think of what on earth they should do. Did Izuku really have powers now? Just like that? "I want you to punch me."

"Excuse me?! But-"

Steam rolled off Toshinori as his muscles grew and his familiar muscle form towered over the still hovering greenette. "My boy, we must know what we are dealing with. I do not want to stay as this longer than necessary, so please just hurry up punch me while I block."

Seeing his mentor hold his arms out in a cross guard, Izuku sighed and put down the mallet in his grasp. He wasn't expecting anything to happen, his strength didn't feel any different.

Oh boy was he wrong about that, as his fist came down towards the man's wrists, the blonde quickly ended up skidding back across the street, making the teen's eyes go wide. "Did… did I do that?!"

"Yes, yes you did." All Might said, shrinking back into his skinny form with a frown and a contemplative look in his eyes. "We need to get you to a doctor right away."

"All Might?"

"Whatever this is…. It would appear you have powers now. Whether temporary or permanent, and whether they are safe is the question we need to ask now."

His green eyes went wide, and he looked down to his gloved hands. "I… have powers now? WHY DID NO ONE TELL ME I JUST NEEDED TO PUT ON A SKIRT?"

All Might let out a sigh, as he once more pulled out his phone and called a taxi, this time intending for both of them to go to the hospital. "I don't think that is how it works, young Midoriya."

After a few moments, the taxi was booked and on it's way and the two could only wait for them to arrive. All Might smirked.

"So, you're definitely going to be able to handle going into a public crowd wearing that?"

"I- WHY WOULD YOU POINT THAT OUT?! NOW I WON't!"

"Hm, well consider it revenge for you hitting me."

"YOU TOLD ME TOO!"

"Did I? I don't recall that." The skinny pro couldn't help but smirk, as their ride rounded the corner. He wasn't going to admit it to his successor but that strike had actually hurt, especially in his weakened state.

"Oh, and young Midoriya?"

"Yes?" Izuku asked irritably.

"Is there anything you need to talk with me about, regarding… this." He gestured over Izuku's interesting new attire. The greenette's glare became much harsher as he picked up the nearby hammer.

"I can, and will hit you with this."

"See, that's not a no."

When the greenette lifted the hammer up with a look of malicious intent in his eyes, the blonde finally relented and escaped into the safety of the Taxi.

as they rode quietly to the local hospital, both had the same thought running through their mind.

'Weirdest ending to training ever….'
