Tiny Trouble! Mistress of Mayhem!

Tsuyu and I were both up rather early for our Work-Study even though we didn't have to be there until 7. I was finishing up putting on my hero costume when I felt Tsuyu's tongue slap against my back! I turned around and lowered one of my eyebrows.

"Sorry, there was a fly on your back." She told me.

"Oh, okay! I was kind of confused there for a second." I chuckled.

I sat down next to her, "So... What do you think we'll be doing today? Do you think we'll be taking down that Mistress Monsoon person?"

"I dunno, maybe? Unless Selkie's wanting us to keep looking for clues." Tsuyu replied.

I nodded at her statement, maybe today would be an easy one?

[Several Hours Later...]

We were making our way to that old cargo ship that Selkie told us about yesterday. This thing looked like it hasn't been used in dozens of years. It was kind of scary, honestly! We docked nearby the vessel and waited for Selkie's command.

"Alright everyone, we're only looking for any sign of Mistress Monsoon. If you run across her or any sort of villain, call for back up immediately." Selkie told us.

"Yes sir, Captain Selkie!" We all saluted.

Tsuyu hopped onto my back and we flew up to the ship as everyone else made their way to it through another side.

"Yuck, smells like rust." Tsuyu noted.

We made our way through the boat. It didn't look like anyone had been here in years. If someone made this place a base, there would be some sort of sign of life here. Tsuyu walked over to the right as I looked around a shipping container.

"Hmm... If I were Mistress Monsoon, where would I be?" I muttered.

I heard something creak, I turned my head and saw a figure standing on a stairwell. The hands of it started to glow and it zapped something towards Tsuyu!

I dove towards Tsuyu, "LOOK OUT!"

It zapped the both of us and I fell unconscious.

*THIRD PERSON*

"That was Leonidus! They're in danger!" Sirius exclaimed.

Selkie nodded and followed Sirius to where she heard Alyx's yelling. It took them only a few minutes to get to where they were. They looked around for the two, but couldn't find them.

"S-Selkie... Sir..." Sirius muttered.

Selkie stepped forward and saw something both adorable and scary! Leonidus and Tsuyu seemingly were children! Leonidus sat up with his extremely baggy hero costume surrounding him. He started sniffling as he looked around.

"W-WAAAAHHH!!! MOMMY! WHERE ARE YOU?!" He cried.

Sirius knelt down next to him, "H-Hey, it's okay! You're alright, we're heroes!"

Sirius wiped his eyes and held him.

"W-What...? H-Heroes...? Is that what you said? I don't understand what you're saying." Alyx replied.

"Crap... Whatever happened, it must've reverted them and their memories. Which means that... Leonidus doesn't understand Japanese!" Sirius thought to herself.

Sirius nodded at him to confirm what he asked. Leonidus hugged her tightly as he calmed down. Selkie picked Tsuyu up, she blinked a few times before ribbiting at him.

"This must've been the work of Mistress Monsoon! We'll have to head back for now, this isn't good in the slightest." Selkie announced.

Selkie and Sirius left the cargo ship. Hiding behind a shipping container was Mistress Monsoon, a smug grin appeared on her face.

[One Hour Later...]

"What? What happened?" Shota asked.

"It's a bit of a long story, trust me, we were trying to find this 'Mistress Monsoon' figure, and it seems as if she found them first. From what it looks like, they're both 7 years old." Selkie responded.

Alyx sat down in front of Tsuyu, he tilted his head at her and smiled.

"Woah, you've got really pretty eyes! Do you have a Quirk too?" He grinned.

Tsuyu stuck her tongue out and placed it on her hand. She quickly zipped it past Alyx's head to grab a fly.

"Woah... Awesome!" Leonidus giggled.

Mr. Aizawa knelt down to Alyx, "I'm assuming you don't know Japanese, right?"

"Japanese? That's the stuff my Mommy gets for dinner sometimes! Or... Was it called Chinese?" Alyx smiled.

"This is gonna be a long week, I can already tell." Sirius sighed.

Eri sat down next to Tsuyu and Leonidus. Alyx looked up at Eri and smiled at her.

"Hi! Do you wanna play with us? I dunno what she's saying though, but still! This girl is really cool!" Alyx beamed.

"Oh, her name is Tsuyu! And I'll play with you guys, do you like kitties?" Eri replied.

"Uh huh! I have a cat! Or at least I think I still do. Hey, Tsuyu, do you have a cat?" Leonidus bubbled.

Tsuyu ribbited and Alyx nodded at her. The three headed into the dorms to play. Mr. Aizawa sighed and shook his head.

"Yeah, this is gonna be one long damn day." He agreed.

[Several Hours Later...]

The rest of Class 3-A returned to the dormitory to giggles of children. Mr. Aizawa stood in the Common Room with the T.V. turned on to children's programming.

"Woah, you watch this stuff, Mr. Aizawa?" Sero wondered.

"No, you guys have a lot of work on your hands. You've been studying your English, right?" Shota told them.

"Yes, why? What's going on?" Izuku chimed in.

Flying around the corner came Leonidus, Eri and Tsuyu. Tsuyu and Eri flew by the others but Alyx stopped in his tracks. His eyes widened with wonder as he looked at them.

"W-Woah... Are you guys Pro Heroes?!" He exclaimed.

Mina gasped with delight, "O.M.G! HE'S SO FREAKIN' ADORABLE!!"

Mina picked Alyx up and hugged him. The other members were confused at what was going on.

"They've been hit by a villain's Quirk; we aren't entirely sure what it is or how long it'll last for. The villain goes by the name Mistress Monsoon, we don't have her motives, neither do we have what she looks like." Aizawa explained.

Everyone surrounded Alyx and looked at him. He no longer had the scar on his left eye. Alyx looked around the room at the different faces of his peers until he stumbled upon a very familiar one.

"L-Laura!" He squealed.

He broke out of Mina's grasp and jumped into Laura's arms. He looked at her and placed his tiny hands on her face.

"Wow, how'd you get so old? Is this what cooties does to you?" Alyx questioned.

Laura hugged him, "You're so stinkin' cute! I could just eat you up! Oh yes I can!"

Momo glared at Laura, she made eye contact with Yaoyorozu and nervously laughed as she sat him down on the floor. Momo approached Alyx and knelt down to him.

"You're really pretty! Can I give you a hug?" Alyx grinned.

"Sure thing, darling." Momo smiled.

Alyx gave her a hug, he looked over her shoulder and saw Kirishima standing behind her. His eyes widened, the same with his smile. He stopped hugging Yaoyorozu and hurried over to Kirishima.

"Hey! You look really really strong! Do you wanna fight me?!" Alyx exulted.

Kirishima picked him up and placed him on his arm, "Still got that eager attitude! Yep, this is definitely Alyx alright!"

"No way... A bird! Do you eat seeds?" Alyx burst out.

Tokoyami shook his head and sighed, "We definitely ARE in for a treat, aren't we all?"

Aizawa nodded and left the dorms with Eri. They all sat down with Leonidus and Tsuyu in the Common Room.

"Alright, so, how about we introduce ourselves. My name is Izuku Midoriya!" He grinned.

"Izuku... Midoriya...? That's a weird name, I like it!" Leonidus chuckled.

Everyone reintroduced themselves to Leonidus and Asui. They showed them their Quirks and what they could do with it. Alyx showed off Gear One of his Overdrive. To their relief, it was still in its awoken state.

"Hey, Alyx, come here." Bakugo spoke up.

Leonidus walked forward and Bakugo whispered something into his ear.

"Kacchan, what are you-" Midoriya tried to ask.

"Fuck!" Leonidus beamed with his arms up.

Everyone looked and tried not to laugh, meanwhile, Bakugo was dying of laughter. Jiro's earphone jack smacked the side of Katsuki's face.

"H-Hey, what the fuck!?" Bakugo growled.

"Bakugo, language!" Momo scolded.

"What the fuck!" Alyx giggled.

Kaminari looked over at him, "Alyx!"

"Fuck." Tsuyu repeated.

"Tsu!" Uraraka gasped.

"Great, now they're both saying it. Leave it to Bakugo to fuck things up." Shinso muttered.

[Later That Night...]

Alyx laid in his bed with newly bought pajamas. He sat up in a bed much bigger than what he's used to. He puffed his cheeks out in thought.

"Mmm... I don't like it here. This place is way too lonely." He muttered.

He slipped out of bed and left his room. He made his way down the hallway, looking at the signs on each door.

"These look weird, is this what Japanese is?" Alyx thought to himself.

He stopped at a random door after wandering the dorms for a bit. He slowly opened it and peered inside.

"Ooh, this room looks fancy!" Alyx noted in his head.

He entered the room and quietly closed the door. Alyx walked over to the bed and climbed on top of it. He sat on his knees as he saw whose room this was.

"Wait, this is the Pretty Lady's room? What was her name again...?" He muttered aside.

He inched his way over to her pillow, Alyx moved himself under the blanket and faced Momo. She was wide awake, facing him, which startled Leonidus.

"G-Geez! I-I didn't think you were awake!" Alyx sputtered.

"It's fine, I'm assuming you can't sleep?" Momo reassured him.

He shook his head, "No, I can't. Could I sleep with you? I'm kinda scared."

"Of course! I don't mind it." She softly smiled.

Leonidus scooted closer to her and held her arm. He shut his eyes tightly as he tried to fall asleep. Momo put her arm around him and cuddled him.

"Nee hee hee! Your pillows are soft, they're softer than my Papa's whenever I fall asleep on him!" Alyx giggled.

Momo opened her eyes and slightly narrowed them.

"P-Pillows?" Momo questioned.

"Isn't that what they are? Like these ones!" Alyx confirmed.

His little hand popped up and patted the pillow that Momo's head rested on. Her eyes widened as he then patted her breasts.

"See! They feel exactly like those! Why don't you just sleep on those instead? Can't you just take 'em off and do that? You could get rid of these fluffy pillows, they kind of make my head itchy." Alyx babbled.

"Alyx, they're attached to my body, dear." Momo replied.

"W-WHAT?! You've got to-go pillows?! That's super cool! I wish I had to-go pillows; I could fall asleep anywhere!" He marveled.

Momo shook her head and smiled, "Good grief... You need to go to bed."

"Okay!" Alyx smiled.

Leonidus cuddled up next to Yaoyorozu, within a couple minutes, he was fast asleep.

"You really must've been a handful, darling." Momo lightly giggled.

[The Next Morning...]

"So, what exactly am I supposed to be doing? Watching kids at the Third-Year dormitory? Why?" All Might wondered.

"Because none of us can watch them, that's why. Plus, I'm sure they'll like you." Shota explained.

"Well, alright. As long as these kids aren't troublesome..." All Might replied.

All Might hung up his phone and entered the dorms. He saw two familiar looking kids sitting next to each other on the couch in the Common Room.

"Hey, Tsuyu, do you like pancakes? They're really good, especially when my sister makes them." Leonidus bubbled.

"Y-Young Leonidus?! Young Asui?! What in the world happened?" He thought to himself.

Alyx looked over and saw All Might. He tilted his head at him before smiling.

"Are you that babysitter that the Pretty Lady told us about? Or was it that Scarf Man? Tsuyu, do you remember?" Alyx chattered.

"Ribbit." Tsuyu responded.

"Well, you'd be correct, children! I am here!" All Might smiled proudly.

They both blinked a few times, Alyx heard a voice that startled him.

"Heya! You need something, Alyx?" Hatsume asked.

"Woah, there's a lady talking to me! All Might, do I have another Quirk?!" Leonidus beamed.

"Huh? Hold on..." Hatsume muttered.

The Interface Mode stopped and Alyx shook his head quickly. Alyx tapped his head and waited for something to happen.

"That must've been Hatsume, she can contact you because she made these contact lenses for you, Leonidus." All Might explained.

"Contact... Lenses? What are those? Are those like glasses?" He asked.

There was a knock at the doors, All Might opened it and saw Hatsume. She walked in and made eye contact with Alyx. Her eyes widened with delight and confusion as she saw that him and Tsuyu. Hatsume rushed over to him and lifted him up into the air.

"Oh my goodness! He's so small how did this even happen did they get hit by a Quirk or something All Might you've gotta have some sort of answer for this right or maybe these are just illusions and I'm dreaming all of this up wouldn't that be wacky?!" Hatsume rattled off.

"You're really crazy! I like you a lot!" Alyx laughed.

Hatsume's head darted towards where All Might was, "HE IS A BALL OF PURE DAMN SUNSHINE!!"

She held out Alyx in front of her towards All Might. Alyx blinked a couple times as he stared at him. He gave All Might a warm feeling smile.

"Good heavens, you're right!" All Might chuckled.

She held Leonidus close to her, Alyx licked his finger and rubbed it on Hatsume's face.

"Geez, you've got a pretty dirty face, lady! Has anyone ever said that?" Alyx remarked.

Leonidus looked up and started to laugh. Tsuyu was sitting on top of Hatsume's head!

"How'd you get up there, Tsuyu?" Leonidus giggled.

"Ribbit." Tsuyu responded.

"How about some breakfast? I'm sure you younglings are quite hungry!" All Might announced.

Both Alyx and Tsuyu nodded at him. Alyx looked over at Tsuyu with amazement.

"You actually understood that, Tsuyu? Awesome!" Alyx beamed.

[A Couple Hours Later...]

Alyx poked Tsuyu and leaned towards her ear, "Hey, Tsuyu, let's see if we can find the other big people!"

"Wouldn't that be scary, Alyx? What if we get lost?" Tsuyu worried.

"Don't worry! I've got a pretty loud scream, if we get lost, I'll just call for help!" He reassured.

Tsuyu nodded at him and the two got off of the couch. All Might was fast asleep, Alyx and Asui quietly made their way to the dorm doors. Tsuyu hopped onto Alyx's shoulders and turned the door knob. They slowly opened the door, they left the dorms and quietly closed the door. The two ran off the porch and towards U.A.

"Oo! What about that big building right there? That's gotta be where they're at!" Alyx pointed.

The two made their way into U.A. They stood in the main entryway and looked around.

"Wow, this place is huge." Tsuyu noted.

"Hmm... If they were big people, they'd be as old as my sister, so would they be on the last floor?" Alyx wondered.

The two found a stairwell and took it all the way to the 3rd floor. They looked at the classrooms and stopped at the 3-A door.

"This has to be it! It's a big letter, so it's gotta have big people it in!" Alyx theorized.

Tsuyu nodded and hopped back onto his shoulders. She grabbed the handle and tried to pull, but it wouldn't budge. Tsuyu moved her head to the left and Alyx started moving left. It slid open as they moved, everyone's attention turned to the door that looked as if it was opening on its own!

"H-Holy hell! Is this place haunted?!" Kaminari exclaimed.

Leonidus and Tsuyu peered around the corner, Leonidus' eyes widened with glee as his theory was correct. They both rushed into the room, Leonidus found Yaoyorozu and stood by her. He held his arms out up to her and she smiled at him.

"Goodness gracious, I'm sure you've scared All Might half to death by now." Momo chuckled.

She picked Leonidus up and sat him in her lap. He sat there with the biggest smile on his face as he looked at Midnight.

"Well, now that we've got little guests in the room, let's continue the lesson. I'm sure they'll learn something as well." Midnight giggled.

Midnight continued with the lesson with the introduction of the little former students. Meanwhile, Aizawa had gotten a call from Selkie with information regarding Mistress Monsoon.

"So, whatever they've been hit by, it can only be reversed by Monsoon herself. No Rewind Quirk or healing one can reverse its effects, neither can it be something they can wait out." Selkie told him.

"What about Monsoon herself? Have you narrowed down her location?" Aizawa asked.

"We've been keeping track of that old cargo ship; she hasn't left since she attacked Leonidus and Froppy." Selkie informed him.

"Alright, I've got a couple more calls to make. Thank you, I'll let you know what we'll do next." He replied.

He hung up and dialed up another number. He made sure to write it down after seeing it in Alyx's phone. It picked up after a few seconds.

"Kariya Leonidus, this is Eraser Head, we need to talk." Shota announced.

AUTHOR'S NOTE:

Heya everyone! This is more of a look into the future (or well, a look into the next Arc after this one), I'm planning on doing more of an extremely early 1 Million Views Celebration set of chapters featuring a whole bunch of OCs from different people! It'll draw inspiration from "Super Dragon Ball Heroes"/ "Super Dragon Ball Heroes: World Mission", but on somewhat of a grander scale. I've gotten one person on board with the idea already (@chandelier_osore on Instagram), but I'd like to get as many people as I can! I plan on making these quite a bit of chapters, instead of just 2 or 3 chapters. This MIGHT BE a DBZ World Tournament Style event, but I think I'll do something else, being that I've gotten 3 or 4 tournament arcs already lol. BUT, if you do have a MHA OC and are interested, let me know right here! If it's not a MHA OC, I'm fairly certain I can find a way to write them in!
