(Hey there and welcome to the very first Kirby x My Hero Academia crossover! IMMEDIATE spoilers for Kirby: Planet Robobot and EVENTUAL spoilers for My Hero Academia. You've been warned)

This is for the people of Dreamland! For the people of Popstar! For the people of the universe!

My Robobot Armor was soaring above Dreamland's atmosphere, the Halberd slowly descending behind me. Focusing only on one of the most powerful beings I've faced, I couldn't spare any time on Meta Knight, except for wishing him safety, before powering my armor's boosters, aiming straight for that insane artificial intelligence.

Raising the right arm, I changed it to it's drill form but I wasn't done yet. Channeling all of my power, I willed the drill to expand, become larger until the drill was larger than the armor itself! Closing in on Star Dream, the nova created a heart-shaped barrier with a sharp flash that emitted from it's eyes.

Getting to work, I rotated the drill arm and crashed into the barrier with force. Speeding up the drill, I smiled internally as cracks started to web out from the transparent shield, Star Dream squinting it's eyes before they shot back open again as I broke through. Rearing the drill arm back, I shot forward again, only to be stopped by another barrier. This process continued another three times but this only made me more confident as it was showing that Star Dream was being backed into a corner. After the fourth barrier broke, I shot above the nova's face and went straight for the super computer that started this.

Climbing high above, I cut the boosters and aimed them away from my objective. Activating them again, the force propelled me right at Star Dream and I slammed the drill into the conveniently screw-shaped top it had. Activating the drill, I began to spin around as Star Dream started to dig into the nova's head. Out of the corner of my eye, I saw the wing-like panels Star Dream has and six of them surrounded me, aiming while charging what seemed to be Star Dream's final attack.

Increasing the speed, Star Dream dug further in and the left outer wing broke off. The other outer wing soon joined it but a quick peek told me three of the six panels have already finished charging. Spinning the drill even faster, the cost was both of Star Dream's inner wings and two more panels finishing their charge. The last panel lit up with the same pink energy exuding from the others as I pushed the armor's capabilities to the limit, the drill reaching max speed and Star Dream now fully dug into the nova.

My heart pumped faster as the last panel finished charging and they all began to make a noise. As soon as the noise started, I let out a determined cry and the nova finally gave. Continuing my yell, I ripped apart Star Dream and drove right through the center of the nova, breaking through until I came out of the bottom. A loud metallic clang rung out and the nova seemed to stop moving completely.

I flopped into my seat and with barely enough energy to stay awake, I looked at the unmoving giant. For a second, I thought I broke through so quickly, the nova didn't even break apart until I suddenly heard an electronic voice.

-WARNING

-CRITICAL DAMAGE TO CORE

-OPENING FILE 'Warp_ '

-FILE OPENED

-ACTIVATING INSTANT MATERIAL TRANSPORT

-HOPPING TO RANDOM UNIVERSE

After that line of dialogue, the nova began to shine a bright light through the cracks my drill made. The white light flickered constantly before stopping completely but coming back with a stronger light for one second before the entire structure blew apart. The approaching shockwave was so powerful that I passed out before it even reached me. Or maybe I was just that tired from killing a nova.

Meta Knight

My ship was slowly being pulled in by Popstar's atmosphere and with literally nothing to do but wait for the ship to crash into the ocean that my men predicted we would fall in, I watched the conclusion of Kirby's battle.

Seeing the pink metal break out of the gray, I couldn't help but be amused at how many different ways Kirby has fought such dangerous threats. Alien robot armor, enhanced inhale ability, super abilities, dragons. The list could go on but I stopped as a voice uttered confusing words in an electronic tone. After it's 'speech' was over, the nova shone and blew up.

Flinching, I braced myself for the shockwave. Getting pushed back, I quickly found my stance again and searched for Kirby. Seeing the pink armor floating in space and not strewn apart in little pieces, I let out a sigh of relief. However, the space previously occupied by the nova was now replaced by the familiar shape of Star Dream but split down the middle into four sections, crackling with exposed wires. The red orb was not destroyed though, merely cracked.

Suddenly, the orb flickered before lighting up and becoming encompassed within a dark mass. The mass swirled wildly and my composure cracked as the surrounding debris was being drawn into the mass. My wings flared in panic as I saw the pink dot now seem so far away from me and so close to the expanding hole in space. In a spur of emotion, I flapped my wings once and flew towards Kirby as quick as I could, even as one of my men yelled at me to stop. But I was too late and Kirby became enveloped by the growing dark mass that I was now approaching with nothing to stop me. Realizing my foolish mistake, I turned back to face the sinking Halberd once more before turning to see my fate. I shut my eyes.

Kirby

Waking up to the glare of UV rays, I discovered that it was morning the hard way. Turning away from the source of light, I slowly opened my eyes but they still stung from the brightness. I guess fighting in the emptiness of space made things seem brighter than they were. Wait.

Where am I? It looks like I landed on a beach facing the ocean's blue horizon. Did I land back on Popstar? That answer seemed the most plausible one and so I relaxed as I took in the world that I had saved. The sensation of wind, the salty air in my mouth and the smell of... rust? And the sound of... grunting and someone hitting the sand.

I sat up and decided to investigate the last two senses. Unfortunately, when I sat up, I saw two long, weird things in front of me. I then freaked out as I found out it was attached to me. Trying to stand, I noticed the long things bend and before I knew it, I was lifted up by these weird things. Letting a confused whimper escape me, I flailed my arms in panic only to find my arms replaced by long, weird things too, except the ends of them had five things jutting out of each.

Letting out a sound of alarm, I fell to the sand as I lost my balance. Slowly lifting my head from the impact, I heard things hit the sand rhythmically and in my direction. Turning my head to face the sound and being weirded out by how my head was attached to my body rather than being the body, I saw a being that had vaguely similar body shape to a Simirror, just that he(?) stood much taller and looked nothing like one. He wore nothing but blue track pants and he had the weird things attached to him too. He had black, curly hair with green highlights on the outside and he was drenched in sweat while carrying a thick rubber tire. He dropped the tire and looked at me with caution and confusion.

"What are you doing here?"

I didn't know why he asked that or why he was carrying that thing but I'll answer anyway.

"Um, I woke up here. Isn't it ok to sleep on beaches?"

Granted, I didn't sleep here on purpose but that's fine.

"Oh, uh, usually you sleep in your house... B-but sleeping on the beach is fine! It's just at this beach, it's usually abandoned and not a fitting sleep spot. You know, Dagobah Municipal Beach Park? The trash one?" The boy said.

What is this place this guy is talking about? I've never heard of a place like this and I've travelled all of Popstar several times.

"No, I don't know. Can you tell me about it?" I asked, curious.

"Well, the currents from the ocean ended up shoring a bunch of trash and then people started using this beach as a means to their illegal trash dumping so this place basically became a landfill. Not many citizens come here. It's known pretty well so are you a foreigner?"

Foreigner?! I thought I was pretty well known around Popstar!

"Last time I checked, I wasn't. Haven't you heard of me?"

"No." He replied simply.

"Kirby? Saved Popstar several times? Oh, maybe it's because I look like this. See, I don't know how I got like this but I'm normally pink, round and none of these weird, long things were on me. I'm actually kind of short."

"Well, K-Kirby, I don't know what you're describing but it's definitely nothing I have heard of before. Also, what's Popstar?"

That made me pause. What is he talking about? This is Popstar we are on right now, right? Or maybe I got pushed from the shockwave to a different planet's pull...

"What's the name of this planet?" I asked.

Midoriya Izuku

"What's the name of this planet?" The weird guy asked.

Why's he asking for the planet's name? Literally everyone except for a few people on Earth knows that our planet's name is Earth! Maybe he has amnesia... No, wait! He said Popstar in a way that says he thought the planet was called that! Oh no, is he crazy? Either he is crazy or there's that other, impossible option that he's an alien... Ah! Stop it imagination!

"W-why do you ask? Everyone knows planet Earth."

"Earth? That's a new one..." He said to himself quietly.

So he is an alien?

"What's your name? My name is Kirby, as you know, and I'm from planet Popstar."

He is! He's being serious!

"Uh, my name is Midoriya Izuku... You don't have a surname?"

"No, I'm just Kirby. Anyways, I need to find a way back home so if you can help with that, I'd really appreciate it."

I guess he really is an alien... He doesn't look like one. Regardless, it seems he really wants to go back home but I don't know how to help him. What would a hero do?

"Kirby. I don't know if I can help you go to Popstar but as long as you're stuck here, you can stay at my house if you don't have a place to live." I offered.

"Really? Thank you! I don't know if I can give back but thank you!" Kirby said cheerily.

"Alright, um, I need to finish something here though so is it ok if you can wait a little?"

"That's fine."

Kirby

After I said that, Midoriya picked up the tire beside him and went down the beach. Getting there in little time, he went up some steps and dropped the tire in a large trash pile. He then went back to the beach and took some more trash. Bringing it back to the pile, this process continued a few more times. Looking around, I can see why he said this place wasn't really active. There was trash everywhere! Not as much as I expected but still! Was Midoriya gonna clean all of this?

"Huff, huff... Okay, I-I'm done for now. Follow me and we'll be at my house." He panted.

Oh right. There is the problem of my feet and arms being replaced by these things. How am I supposed to move! Wait, I kind of resemble him in shape so maybe if I look at how he walks, I can learn. Ok... I'm sitting with my lower weird things straight out in front of me. So I'll bend both of them and then I just have to get my upper body on top. I'll try pushing off the sand with my upper weird things. I did it slowly but I eventually balanced on my lower things and then straightened them like how Midoriya was standing. I did it! Lifting my left foot, I promptly fell on my face to the sound of Midoriya yell in surprise.

Finally! I told Midoriya of my old body and if he can help me walk in this one and after an hour, I finally got the hang of it. Turns out the lower weird things are called legs. The upper weird things are called arms but they look nothing like my old arms. And then there's my 'hands'. Midoriya taught me how to use them by having me pick up some things around the beach and I eventually got used to it. This is so weird but I can think of that later as we arrived at Midoriya's house.

"Mom?" He tentatively said.

"Izuku! You were out later than normal! Where were you? And who's this?" A woman asked who I assume is his mom.

"Oh mom, uh, his name is Kirby and I found him on the beach. He doesn't have a place to stay so I was hoping he could stay here..?"

"Oh Izuku, you're so selfless. Of course he can stay here. But why were you on the beach with no place to stay?" She turned to me.

"Oh, I was-"

"-He's an orphan a-and he didn't like the place he was at before and left to the beach!" Midoriya cut me off and lied.

He turned to me and shook his head and I think I got the idea. But why didn't he want her to know I'm not from this planet?

"Kirby, that must be rough. Come, it's time for breakfast."

Smiling, I couldn't help but beam at the prospect of food.

"Yes!" I cheered.

"'Kay mom." Midoriya added.

(Hope you guys enjoyed this! Don't know how this will turn out but I'll keep going, regardless)
