Once upon a time, a ship crashed on a planet.

Planet Popstar, the World of Miracles. Dreamland, the Land of Peace.

The ship held naught but a baby, a little pink bundle of joy born of the Void and blessed with immeasurable power.

But with great power came great responsibility, even in the hands of the fledgeling Star Warrior.

Threats flocked to the planet. The light attracted the dark, and the dark preyed on its lazy defense.

Yet, the baby protected them all. The fledgeling warrior grew strong, grew up into a Star Warrior, with the aid of his many friends.

He loved them. He loved his home. He would protect them forever.

Until he couldn't.

Until an enemy finally overpowered him.

Until his endless reserves of strength finally depleted.

Kirby couldn't have done it forever.

But time repeated itself, and on a distant planet, in a faraway town, in another universe,

The Warrior rose again.

Kirby took a nice long deep breath. The breeze tousled his hair lightly and swayed the branches of the tree above him. Specks of light danced on the ground, leaves rustling quietly in accompaniment with the soft chirps of birds.

All was calm. All was serene. From his relaxed position, lying on the grassy hill overlooking the land, he stared up, up at the wispy spiral clouds. The fresh scent of the spring breeze carried with it the promise of peace and quiet. Kirby liked it.

Then, creeping in like an unforetold storm, the sky darkened. Kirby's eyes widened as a large red eyeball peeked out from the mass of darkness, rolling around as if stretching after a nap, then finally, landing on him. The mass of black spread far and wide, lowering, settling into and corrupting the land, the quiet natural beauty of it darkening.

"Kirby!" shouted a few voices in tandem, ever familiar, but ever distant.

But all he could do was stare up at the eyeball, the black cloud, descending on █████████ and engulfing his home—

Kirby gasped, as he sat up on his bed.

The birds were chirping, the sounds of the nearby city awakening with the small vrooms of cars rolling past reaching his ears.

Kirby arched his spine and raised his arms in a satisfying stretch, before letting them flop back down the the soft downy bed. His eyelids still drooping, he raised one hand to rub the fog away from his eyes, and hopefully wake up more fully.

It was another one of those dreams that Kirby couldn't make heads or tails of. So realistic. He could feel the soft bed of grass that padded his back but tickled his skin all the same, the small bits of sun peeking from behind the tree that warmed his skin. The horror of seeing that ominous red eyeball. He didn't know what they meant.

But then again, Kirby was never one for thinking too hard about things.

With a single smooth motion, he hopped out of his bed and landed on light feet. His eyes were wide open now, revealing deep sky blue eyes that reflected the atmosphere of a sunny day and shone with the light of a thousand galaxies in the indigo night sky.

A joyous smile perched on his lips, he made a short futile effort to pat down his puffy pink hair, before bouncing to the kitchen. Standing at the stove was none other than Meta Knight, Kirby's caretaker. His blue hair was brushed down and much more orderly, but he couldn't really say anything about Kirby being messy when he was wearing a literal blanket on his back.

Kirby noted that Meta wasn't wearing a mask today, which meant it was an off day, thankfully. Kirby would get to spend time with him! He smiled, despite knowing that the knight would probably spend half the time teaching him rather than playing with him.

"Good morning, Kirby." The stoic knight turned to face him as Kirby scrambled into his seat at the dining table. "How did you sleep last night?"

Kirby shrugged. "It was alright, I suppose. Another one of those weird dreams." He made a habit of telling Meta most things. The blue-haired knight was, after all, more knowledgeable. "This time was another red eyeball, but with a lot of black stuff? Black stuff, that sank into the ground," Kirby briefly explained.

He wasn't the most eloquent person, but Meta understood. "Hmm," Meta hummed in consideration, probably cataloguing the dream in his thoughts. Kirby was glad Meta did that for him so that he didn't have to. Meta probably had them all memorized to the T, whereas all Kirby knew was that red eyeballs appeared more often than he would've liked. They were creepy.

Other than that, Kirby recalled the appearance of a wasp, a crown, and some star-covered cape. They were odd, but Kirby felt like he had seen them before. Deja vu, perhaps.

It wasn't like villains were uncommon. In their location at Musutafu, villain attacks occurred maybe once a day at least. More, even, with the high concentration of heroes in the area. It's just… none of those villains were large red eyeballs, nor did they make massive beanstalks to worlds in the sky or machines that could rip you apart in seconds—

Scratch the last one out. That was definitely possible, Kirby thought.

He was broken out of his musings by the clinking sound of two plates being placed on the table, piles of steaming hot scrambled eggs and bacon on top.

Taking a large bite, Kirby gave Meta a thumbs up for this one. The corners of the knight's mouth turned up with a miniscule smile, and Kirby grinned.

When breakfast affairs were done and over with, they moved over to the living room, where Meta set up a workspace for Kirby, as the child watched, pouting.

Really, he wasn't a child. He was 16. His outer appearance hadn't changed since he was 12 or 13 though, giving him a much more youthful appearance— not that he complained. It was often better to be considered a child; children were more pampered. Kirby liked it when the people at Meta's hero agency would sneak him a lollipop from Meta's stash (often behind the knight's back).

Kirby wasn't the brightest tool in the shed, but if he was a good fighter, then Meta was an excellent teacher. The hero homeschooled him since he was six, and Kirby had mastered most of English and some of math.

Something about learning from the knight always just felt simple and easy. It was like Meta knew everything about Kirby, from how he thought about and conceptualized certain points to how slow or fast he could calculate something. His homeschooling curriculum had been nothing short of perfect for Kirby, and the fruits of his efforts was a Kirby that, while slow at times, had a deep understanding of the world around him.

That didn't always mean it was fun though, which is why Kirby was pouting. Today he was doing more practice on physics and engineering, something Meta always insisted was important even though Kirby had yet to find an application for it.

Learning wasn't the bad part. It was Meta Knight's drills.

"Finish this problem within the next 2 minutes," Meta commanded.

Kirby didn't.

"Drop down and give me 20 push-ups."

The boy grimaced with annoyance, but still complied. He was up and done before the minute was over without even breaking a sweat, but it was still annoying.

Kirby liked it better when Meta Knight made it a game of sorts, making him climb up trees to find a problem and solve it before jumping back down with the solution to exchange it for a treat. Those had dwindled in the past few years, sadly.

But the real fun always came when Meta Knight's phone would start beeping obnoxiously. Meta's eyes would harden from their soft white-ish yellow into a sort of sharp gold with the alert of a villain attack. His blanket over his back morphed seamlessly into a large collared cape with golden trims, and he went to gather his armor and shoulder pads.

With those equipped, a large M emblem emblazoned on his shoulder pad, he would slip on his metal mask with the chevron eye hole to complete it and be on his way.

Not before Kirby begged to go with too though. Really, more recently, he hadn't even needed to ask; Meta would just automatically assume he was coming. Which, of course, he was.

Meta would pass Kirby some silver and mahogany armor and a smaller round mask, and Kirby would join him as they jumped across the rooftops, toward their location or just scouting.

Kirby loved the feeling of flying. What they did wasn't flying, per se. It was jumping really high and landing after seconds of floating in the air. But still, the feeling of wind ruffling his hair and his floppy sleeves rumpling around as he lifted off, soaring, nothing to hold him back…

In short, it was the most amazing feeling.

His euphoria was broken when Meta landed on a flat rooftop around 4 stories tall, and pointed to a blob of green on the ground, in the middle of a narrow shopping district.

It was a villain, probably with some sort of liquefying quirk on himself. It looked more like a pile of goop with eyes than it did a man.

Kirby squinted at it from the high vantage point they had. And then jumped back when the place exploded into bright orange embers that flashed angrily.

"Be cautious, Kirby. Tempted as you may be to use Fire, remember that you still wear a mask," Meta Knight warned.

Around and nearby, Kamui Woods came on scene, as well as Backdraft. Kirby could immediately tell that Kamui Woods was being burnt as he rushed away, rescuees entangled in his wooden limbs, while Backdraft was struggling to keep the flames at bay.

Every hero had been put in a stand still, and every hero was left standing, waiting, waiting for someone with a more suitable quirk.

It was a slime villain though, so it shouldn't have been able to cause such a large pyre… Kirby's eyes widened as he realized that the slime thingy must've been possessing someone.

They widened even further when he caught a glimpse of a green-haired boy racing towards the mess, arms flailing and legs running sloppily.

To his side, Meta still muttered, having not yet seen the boy in danger. "A slime villain, likely possession. Maybe not the best idea to use a sword here, it might not have any effect on a fluid body— Kirby, wait!"

The boy didn't. He jumped before Meta Knight said anything, fully intent on acting before thinking. Meta Knight sighed. Kirby was always like this. Resigned, he hopped down from his perch as well, Galaxia drawn and poised at the ready.

As Mount Lady arrived on scene to be obstructed by the nearby buildings, so did Kirby, landing in the middle of the fray where the heroes stood, on his red boots from high in the sky with nary an impact, his mini-sword of aqua and white steel drawn.

The sounds of battle rushed into his mind. The crackling flames, shouts for aid, loud instructions, whooshing water, punches filled by the fluid form.

A nearby news reporter relayed the developments: "Rookie heroine Mount Lady has arrived on scene, as well as the number 3's masked sidekick, Mini-Knight! Meta Knight will likely be following soon."

And Kirby jumped into the fray.

The flames were everywhere, their noxious scent filling the crevices of his mask, but Kirby pushed through, hacking at pieces of slime.

There was no give. His blade slipped right through, like a knife through running water. Kirby quickly sheathed his sword on his belt and raised a foot, unleashing a powerful blast of a kick on the green sludge, which parted at the location of impact.

Kirby ran through quickly before the slime regenerated, and kept on going. The eyes were nearing. Kirby could make out the garish yellow fangs and the buggy red eyes illuminated by the rampaging fire.

There. In the middle. An untamed mane of light blond hair and wide, angry red eyes, a bed of fluffy green hair on a worried face of freckles.

"Your eyes seemed like… you were calling for help!" The green-haired boy said, tears overflowing from his eyes, as he desperately clawed at the sludge to no avail.

The sludge formed an arm, a gooey barely-held-together limb of disgusting green substance, raised menacingly in the air, poised to attack—

Kirby rushed forward, he had to do something—

Boom!

Smoke burst forth from the explosion, pouring into the street and rolling out, shouts of heroes piercing the air.

There was a moment of deathly silence.

One second.

Two seconds.

The audience watched with bated breath.

Then, the smoke lifted, faded as it floated into the air, and with a momentous burst of white light, new flame was ignited.

On top of the tiny hero's pink bed of hair was a flaming hat. The clasp on the back of his head that held his perpetually worn metal mask was absent.

The crowd gasped. Was the mini hero going to be revealed this day? Was he going to finally be unmasked?

Izuku looked at the sidekick to the number 3 hero, wide eyed. Mini-Knight, as they called him.

Even in such a perilous situation, he could remember clearly that not once had this hero been out without a mask. And now that it was gone, Izuku was staring astonishingly at the face of a child.

He couldn't have been any more than 12. The blue eyes that always glowed ominously cyan below the white metal mask were so deep, filled with emotion. Relief, worry, anger, joy, excitement, so much in so little.

With eyebrows furrowed and a small smirk of determination, the tiny hero stood.

As abruptly as the hat of fire appeared, it had disappeared, dematerialized, left with a mini burst of light.

The slime villain, Katsuki, and Izuku couldn't even see the quick motions Kirby took as he grabbed the aqua hilt of his sword, a new green pointed hat replacing the dancing flames on his head, and with a flourish, a crescent-shaped beam of energy rent through the villain's impregnable fluid body, splitting it.

Katsuki took choked gasps as the sludge villain fell away from him, it's fluids leaving his body as disgustingly as they had entered before, but leaving him this time, lungs finally free.

But as soon as the beam was gone and the smoke started fading more, the hero quickly dashed to where his mask had fallen on the ground. The green hat dispersed as well as he slipped the mask on in a single practiced motion and jumped up to the roof of a nearby building.

What… what was that?

Nobody understood.

The hushed mumbling quickly turned into cheers though, as the large muscular body of the iconic All Might appeared in the street.

The battle quickly ended with the number one hero there.

Heroes scolded Izuku while they praised Katsuki, and neither Meta Knight nor Mini-Knight were anywhere to be seen.

"Kirby," Meta started.

He already knew what was coming. "I'm sorry." His head hung in slight shame, but he looked back up, determined. "But I will not stand by as people get hurt."

The Knight sighed. "What's done is done. It's alright. You did well."

Kirby looked back up at the Knight, eyes wide with surprise. "I thought you'd be more angry."

Meta Knight was unreadable under the mask. But he rested his hand on Kirby's head, and fondly tousled his hair. Kirby nearly purred.

"I am," he said. Kirby slumped at that. "I expect 100 of each drill when I get home.

But I am also proud. And you did well today."

The boy looked up and grinned at the knight.

Later that day, Izuku took the first step towards his dream as he accepted All Might's power. Reduced to a crying mess on the ground from his gratefulness, it only occurred to him to ask much later, after All Might had explained his training regiment to him.

"All Might, do you know Mini-Knight? Number 3 hero Meta Knight's sidekick?"

The large hero looked curious, but nodded. "We've worked together once or twice. Why do you ask?"

Izuku frowned. "You know how he unmasked himself today?"

All Might nodded. "I was in the back of the crowd, yes."

"I think the only ones who saw were me and Kacchan, but… he looked so young. Younger than me," Izuku bit his thumb nail in worry. "I mean, I know he's strong, he's been around since halfway through Meta Knight's career, but has he been trained? Is it safe for him? How did he get there?"

All Might placed a spindly hand on his chin, considering it.

He hadn't seen it up close, but if what Midoriya said was true and a child was working as a hero— no, vigilante— then he needed to be reported. Heroism was not a game, and if a child was out there, then he could only think that the pro heroes must've been doing something wrong.

Though, he didn't want to discredit the hero. He had accomplished multiple feats in his time alongside Meta Knight, and to stop someone of such high potential seemed like such a waste. All Might was not lying when he said that he had worked with him once or twice. While it was always in the presence of his mentor, number 3 hero Meta Knight, he himself was also given ample time to shine.

The child— how had he not realized before? He was too ridiculously small to be considered an adult even with the variety of quirks in the world, too joyous and naive to be fighting so much crime in the world— he was still strong. He showed the same enhanced physical strength as his mentor, and a certain deftness in fighting that told of years of experience— more than he should have.

He frowned.

"—debuted 4 years ago without an official name but alongside then number 5 hero Meta Knight during a small robbery, quirk unknown but jumps high and has enhanced physical strength and endurance—but that fire hat? And the beam of energy, no one else in the vicinity had any sort of quirk so it must've been Mini-Knight's but—" Midoriya mumbled next to the number one hero.

He poked the boy, startling him out of his musings.

"Ah! Yes, what?" Midoriya jumped, hands gesticulating wildly in surprise.

"Calm down, my boy." All Might was impressed at Midoriya's thinking, but it was excessive. "I'll report it and get back to you on it."

Meta Knight picked up the phone, knowing that he had to.

He huffed. He didn't usually get called by the Hero Association unless it was concerning his pay.

"Is this Pro Hero Meta Knight?" asked the robotic-sounding person on the other end of the line.

"Yes, this is he," Meta replied. "What is this about?"

"Your undocumented sidekick, unofficially termed Mini-Knight, has been charged with underage vigilantism and illegal quirk usage. Please bring him in for a discussion of the consequences."

Meta Knight nearly swore. Of course this would happen. "He will not serve jail time, correct? Vigilantism is punishable but he has followed all other Hero guidelines," he tried to reason.

The voice on the other end of the line sighed. "We dislike this just as much as you, sir. Rest assured that he will not be imprisoned. We just need to have him authorized for duty as soon as possible."

With a click, the line died, and Meta was left contemplating the options. He pinched his nose bridge. Of course the one time Kirby revealed his face to save someone, he'd end up causing something like this. They had such a good system going, too.

"Kirby!" He shouted in his no-nonsense voice, still standing next to the phone. "Come here! We need to talk!"

Light footsteps sounded from the hallway of Kirby's bedroom as the boy rushed to where his mentor was. When Meta Knight used that voice, it was in his best interest usually to follow Meta Knight's instructions, or risk frustrating the knight even further. Kirby wanted a not-disgusting dinner tonight, thanks.

"Yes?" He breathed as he halted in front of the knight.

Oof. Meta was pinching his nose. That meant Kirby was in for it. "How many people saw you unmasked today?"

Kirby looked up, recalling the moment. It was quick, okay? He didn't really remember off the top of his head, but… "three, I'm fairly certain," he replied. "Just the blond guy, the kid with green hair, and the sludge villain."

Meta raised an eyebrow. "You're certain?"

Kirby nodded slowly, unsure where this was going. "... yes?"

Sighing, the knight pointed to the phone. "I just got a call from the Hero Association. It appears you've been reported for underage vigilantism and illegal quirk usage."

Oh, heck no. Kirby's eyes widened. "Did one of them report me?"he asked quickly. If he was stopped from going out with Meta Knight again, or there were any worse repercussions, Kirby didn't know how he'd ever do anything again.

"One would assume so, if they're the only three to have seen your face," Meta Knight reasoned, voice calm and steady as Kirby panicked. "You've been requested to meet them and discuss your punishment, though it shouldn't be anything too serious," he explained.

Oh no.

Herro! Back with yet another Kirby crossover (in gijinka form again), but don't read my other one; I'm considering deleting it. Anyways, as usual, the Kirby fandom severely lacks crossover fics, and I seek to rectify this, so here's a crossover with BNHA. I hope you read through! I assure you that it'll be pretty different from the usual 'character A joins class 1-A.' At least I hope so. I'm trying my best!

This is actually inspired by carloshbaroni's My kirby academia, which I enjoy quite a bit. The grammar is rough, but the ideas were really great, so I wanted to try something.

With all that said, thanks for reading! If you enjoyed, please leave a review, fav, and/or follow! Reviews absolutely make my day, and I'll try to respond to all of them! (^-^)
