This is just going to be a short story, it may even just end up being a one shot... not sure at the moment. Just a little thought I had for My Hero Academia. This takes place after all our favorite students become Pros. I have not read the manga, but I am caught up on the anime.

...

"Kacchan!" Deku, Symbol of Peace and Pro Hero, shouts as he wrangles down one of the villains with an escaping type quirk. Kacchan, another rising Pro, grunts as he uses his explosive quirk to knock out the villain he was currently fighting. They were in downtown Tokyo working a job together on a series of heists led by an eight-man crew. Currently, the ringleader with an unknown quirk was the only one they hadn't managed to subdue. "Down the alley, one got away!"

Kacchan sprinted down the alleyway that Deku nodded to as he finally managed to get the villain he was fighting subdued. Kacchan could already hear the distant sirens of police officers flocking to the scene.

The woman villain was cornered in a back alleyway with no one to aid her.

"Give up!" Kacchan barked at the woman who scowled. Deku stepped forward to handle the talking.

"Villain, you're surrounded, surrender yourself," Deku said calmly, standing alert. His green locks swayed in the breeze. The woman with bright, violet braids and a skin-tight bodysuit remained uncooperative.

"You'll have to come and get me!" She spat defiantly. Deku frowned, calling out for her to surrender once more or she would face the consequences. The purplenette simple grinned at the two Pros. Kacchan decided enough was enough and made a mad dive for her, his palms sparking.

"Kacchan, wait!" Deku screamed as he propelled forward with One for All in time to knock Kacchan out of the line of fire as the villain shot a beam of light the encased Deku and slammed Kacchan against the brick wall, knocking him unconscious.

...

"-chan, Kacchan, Kacchan!" I groaned as I slowly came too. A squeaky voice kept calling my name... It was a familiar voice, but I couldn't place it. "Kacchan, p-please come b-back!" The voice was being choked up by unseen tears. Little hands tapped on my face as I grunted in annoyance. Deku does this every morning so we can eat together. I blinked away the blurry spots in my vision as a green lump began to take shape.

"De-ku..." I groaned as I sat up slowly.

"K-kacchan! You mi-ight have a concussion, lie back d-down," that small voice chirped through their tears. God, such a cry baby. They remind me a little of Deku back in our youth.

Deku!

I snapped to attention and began taking in my surroundings. The villain had escaped, most likely having knocked Deku unconscious with her blast, which also incapacitated me giving her the opportunity to escape. Shit! Next to me was a small child with green hair, and Deku was not... In... Sight...?

A small child? Come again?

I stare down at the child in confusion.

His hair was a thick and unruly green mess, little freckles dotted his chubby cheeks and emphasized his round, light green eyes that were filled with tears. The small boy was struggling to hold up the suit that swamped him, the hood with bunny-like ears drooped.

Deku?

"Izuku is that...?" I blinked several times, stunned. There, sitting beside me with tears streaming down his cute, little face, was my husband. As a fucking child.

"K-k-kachan!" Deku sniffled, "I-I'm scared."

"Hey!" I snapped, causing Deku to stiffen in fear. Shit, I can't raise my voice at him. I studied his further. Deku couldn't be much older than six physically, but who knew if this was six-year-old Deku or twenty-five-year-old Deku in a six-your-old Deku body. I took a deep breath, "Deku, how old are you?"

"S-six," Deku shuffled his little feet, almost falling in the process. "Why is Kacchan so big?"

"Why are you so small, idiot," I snapped back as I pushed myself up onto my feet. I knelt in front of Deku and took his hands. "Izuku, I don't know what happened, but we're gonna fix this, alright?" He nodded his head and wrapped himself around my neck. I sighed and stood up with my miniaturized husband cradled in my arms. I had only been out for a few minutes and it looked like the police had handled the criminals we left back on the main street. I approached the head detective in hopes of finding a solution.

"Ground Zero, if I could take your state-" I cut him off before he could go any further.

"Detective, this is Hero Deku in my arms right now. He was hit by the ring leader's quirk which appears to be some sort of age-reversal quirk. Currently, Deku is both physically and mentally six-years-old. I need him to be medically examined immediately," I commanded the shorter man who nodded and called for one of the officers to call for an ambulance. "Now, I need to know if the leader has been apprehended, or if she's still on the loose."

"If you didn't get her, GZ, then she's still out there," the Detective, Detective Hiro, said. "I have men on the ground searching for her as we speak."

"I'll make some calls myself to a few colleges," I frown as I hand Deku over to a paramedic.

"K-kaachan!" He whimpered, eyes watering more.

"Deku, it's going to be fine," I assured him, patting his head gently. "I have to talk with the police real quick, and while I'm doing that this nice doctor is going to make sure you're okay. I'll come to get you when I'm done." Little Izuku's lower lip trembled, but he nodded his head and went with the paramedic. I gave my statement to the officers, including a description of the criminal still at large. Once I was done I called back to Best Jeanist's office and requested a joint operation with Uravity.

Midoriya Inko passed away two years ago in a car accident. Izuku had taken it really hard then, and I don't know how he'll handle it as a child. Ururaka is my best bet on being able to console him with motherly love and whatnot.

"Alright, Ground Zero, I'm patching your location to Uravity right now," the handler on the line said once the paperwork had gone through.

"Thanks," I hung up. Ururaka will be here soon enough. It's been nearly forty minutes, and Deku's probably about to freak out. I made my way over to the ambulance that was parked behind all the police cars. As I approached I could already hear Deku's sniffles. Part of me was irritated at his babiness, the other part was... concerned. Maybe it's because we've been married for three years now, and been together for almost eight, but little Deku wasn't nearly as annoying as I remembered him as.

"Kaachan doesn't w-want me!" I could hear Izuku sobbing the closer I got. "I-I-I'm quir-r-kless -hic- l-loser." I felt my chest squeeze at the heartbrokenness in Izuku's muffled cries.

"Hey!" I barked gently, causing the little boy to jerk up, his face covered in tears and snot. "I told you I'd be back. Here I am."

"Kaachan!" Deku cried out, launching himself at me. Thankfully, I have fast reflexes. I shifted Izuku onto my hip as he buried his face in the crook of my neck. I could feel the snot and slobber soaking my shirt.

"Deku," I sigh, trying to hold onto my patience. "A friend of mine wants to meet you. Her name's Ochako Ururaka, and she's a hero."

"... Like All Might?" Deku hiccuped as he peeked up through his green curls. God, he was so fucking cute.

"Yeah, her Pro name is Uravity. She has this really cool quirk." I continued. Izuku seemed to perk up a little.

"It must be very cool if Kaachan says it's cool!" Deku declared with a bright smile. "What is it?"

"She has an Anti-Gravity quirk." I scoff at Deku's logic. His eyes began to glow excitedly.

"Woah!" He exclaimed. I felt my lips begin to rise a little at his enthusiasm.

"Yeah," I said as I leaned against the door of one of the cruisers. Little Deku sat cradled on my forearms as he straddled my stomach. His chubby cheeks were flushed, and his green eyes were red and swollen from crying. Staring at what had become of my husband, I felt conflicted. On the one hand, the one behind my back, I wanted to pinch his cheeks and cuddle with him on the couch while watching a Disney movie marathon. The other hand slaps me across the face, however, reminding me that this is my husband, not my non-existent child, and I prefer the adult Deku.

"Ground Zero!" I look up to see Uravity staring at me. Her eyes travel from me to Deku and widen comically.

"Midoriya?" She gasps. Deku perks up at the sound of his name. He studies Ururaka, then he looks up at me.

"Is that...?" He whispers loudly. Ochaka coughs to hide her giggles.

"Yeah, Deku," I sigh. "Izuku, meet Uravity, Uravity meet... Well, whatever." I grunt, scowling. Izuku smiles at Ururaka shyly, awkwardly bowing in my arms and greeting her respectfully.

"I see why you requested a team up, Ground Zero," Ururaka said as she studied Deku. Izuku blushed and pressed his face back into my neck. I swear flower seemed to explode around Ururaka as she squealed. "He's so cute! I need a picture." She whipped out her phone and began taking snapshots as if she were a professional photographer instead of a Pro Hero. "Smile, Deku!"

"Stop it, Uravity," I growl as Deku seemed to shrink further into my chest. Ururaka sighed and slipped her phone back into her utility belt. It took a minute to coax Deku out of his not-so-great hiding spot, but he finally dropped all formality with Ururaka and was asking her million-and-a-half questions about her quirk and her work as a Pro. He even let her hold him. By the time dusk fell on Tokyo, Deku was fighting sleep as his arms hung loosely around Ururaka's neck. "Lemme have him," I grunt, gently tugging Deku into my arms. His head fell onto my shoulder and he was out like a light. His light snores caused Ururka to giggle.

"You'll be a great dad, Bakugo," Ururaka smiled at me. It took everything in me to not blow her face off. I grunted softly as we began walking to the car waiting to take us to my HQ. "Why did you call me on the case, Bakugo?"

"... So far it looks like the quirk user that did this to Deku has some sort of age reversal quirk. Currently, Deku is mentally and physically his six-year-old self, meaning he has no idea who most people in his life are save for me, my family, and... His mother," Ururaka stopped walking.

"Oh..." She breathed, eyes filled with remorse. "He doesn't know..." I shook my head.

"I don't want him to know if we can avoid it. Deku's smart, even when we were kids, it took everything I had to stay ahead of him," I huffed, thinking back to kindergarten and elementary school. "He may connect the dots on his own. Or he may be too young to even consider the possibility of Inko being..." I couldn't even say it for fear of Deku waking and hearing me. "I need you to help me keep him distracted from the fact that Inko isn't here."

"I'm not sure that's a good idea, Bakugo," Ururaka replied, "Deku is already attached to you. You even said he recognized you before you regained consciousness in that alleyway. I think that maybe a small part of our Deku wasn't reversed. The part that you married. He didn't recognize me at all, and we've been friends since our first year at UA. It's best if he stays with someone he's familiar with... He'll recognize your parents!" I glanced in the rearview mirror at the booster seat where Deku was strapped in. Drool was dripping onto the new shirt that he was given after he was looked over by the EMTs. "Just tell him he's having a sleepover at your parents' house while we work the case. Maybe the whatever is affecting him will wear off within the next day or two."

"What if it doesn't," Ururaka frowned. "What if... What if my husband is permanently a child?"

"Bakugo," Ururaka placed a comforting hand on my shoulder. "We're going to get Izuku back. We're going to catch that fugitive, and we're going to do it in the next two days. I can feel it. But, I think you should stay with Izuku."

"What?" I snapped, causing Deku to jolt in his sleep. We hold our breath, and he dozes back off. "What do you mean, 'I should stay with Izuku?'"

"You're too close to this case, Bakugo," Ururaka crossed her arms, "You're emotionally compromised. If something goes wrong, that falls onto you, and Izuku will have my head if he finds out that I let you work a case like that. You know that it is a huge risk for you to continue in this case. That's why Todoroki and Iida are going to take your place. I've already texted them to set up the debriefing tomorrow." I grind my teeth together, my blood boiling under my skin. I can't argue with that logic, no matter how much I want to. I finally sigh and agree with a triumphant looking Ururaka. "Besides, this'll be great parenting practice for that future baby Izuku want."

Oh shit.
