Adventures of My Mad Scientist

Summary:

one day AFO decided to get a gift for his boyfr- *ahem" colleague, and happens upon a young quirkless boy. (What a great gift!) After snatching him up and taking him to the lab, Kyudai is far less than impressed, especially when the kid ESCAPES and gets lost in the underground bunker, and now they have to find the rabid thing before he breaks anything.

-OR-

Gaaaaaay mad scientist and supportive evil overlord practice too much sympathy and end up with a kid!!!!! (Or two or three)

I'll update when I feel like it, it's mostly fluff or science. They're not too gay, but they're quietly in love, kinda like in Hannibal.

(See the end of the chapter for notes.)

Chapter Text

“Frankly… It's adorable.” 

 

     “I'm a he!”

 

“Frankly, I agree.”

 

     “Are you guys ignoring me?”

 

“What do you intend to use this one for?”

 

     “Mommy said it's not nice to ignore people!”

 

“What do you mean? I brought this to you.”

 

     “You guys are so mean.”

 

“I- boss, why would you kidnap this child and risk exposing yourself to the public?”

 

     “... Are you even listening to me?”

 

“You uh mentioned that new project of yours… needing a canvas or something… so I got you one. Is it not satisfactory?”

 

     “you're ugly.”

 

“... All for one… ahem. I appreciate the gesture. This canvas is more than satisfactory. Thank you.”

 

     “this place smells.”

 

“It was no problem for me.”

 

     “oo- whats that?”

 

“of course it wasn't. Still, this gift does not negate the fact that you've risked your position! Our utmost priority is secrecy and you've completely exposed yourself! This was reckless and incompetent.”

 

 

 

“Oh hush. You would do better to show your gratitude next time. And do know that I took great care in keeping myself hidden. You should expect no less from me.”

 

 

 

“Of course sir, I just urge you to be more careful-”

 

“Doctor, you ought to know that the child is no longer in the room.”

 

“WHAT? You didn't restrain it?!”

 

“I didn't know I had to! The child was behaving fine!”

 

“... Alright, well help me find it before it gets out and compromises the lab.”

Chapter Text

 

“Your goggles are funny”

 

“They're necessary.”

 

“They don't look necessary. Why would they be green if they help you see?”

 

“They're green because I said so.” 

 

“Really- is that your quirk? You can change the color of your goggles? And it's voice activated? Or are they a support item and your quirk is something else? Either way that's so cool! Can I wear them?”

 

Kyudai barely glanced up from his work to look at the fluffy green child who was peering into the chest cavity of the body he was working on. 

“No.”

 

“Okay. Whatcha working on?”

 

The green was unfazed.

 

Garaki sighed. Loud and deliberately. “This is delicate work. I would do best with you not chattering away and risking infection. Why not sit in that chair and wait for me to be done.”

 

The child huffed. Like the child it was, and refused. “No, I'm alright.”

 

As quick and sassy as the retort was, so was it's actions. Garaki was especially grateful that the thing understood what an infection was, and pulled away from the body.

Though his heart rate was up again when the child did not go to the chair as instructed, but instead wandered in the direction of his desk.

 

His desk! With hundreds of files worth of classified information. Plans, analysis, instructions, blueprints, floor plans, profiles, data, locations, and even a perfectly organized and itemized list of All For One's personal information; from his meal plan, to allergies, to favorite foods- and worst of all, weaknesses.

 

Though Kyudai, in all his centuries of experience, couldn't remove his hands from the surgery until it was finished, or at least until he was 100% sure the canvas wouldn't die if he left for a minute.

 

He could hear the soft shuffling of the kids feet(a little habit he noticed over the past few days while the thing hid in the lab), and the rustling of papers on his desk. He knew better than to tell the child to stop, for risk of encouraging it more, so he quickly (and quite patchily) closed up the stomach and threw the tarp back over the body before tearing off his gloves and scurrying over to the desk.

 

“This is my desk.” He hissed, grabbing the rolly chair and pulling it away.

 

And this damn child said- “I thought so, your names on all the papers and the computer won't turn on.”

 

“I never use the computer, that's why it won't turn on”

 

“But why not? You won't have to write on paper if you use the computer.” The child said as he leaned over the edge of the chair and pushed his feet on the floor to make the chair spin.

 

The Doctor grabbed the chair to stop it's spinning.

“Because it's easier to hack into the Internet than steal from my desk, which is why you can't touch anything.

 

The kid stared for a bit, its wide green eyes blinking

as it thought.

And then- “I'm hungry.”

A sigh. “I'd assume so, you've been hiding down here for three days. If you allowed yourself to get caught sooner we would've fed you.”

 

The child fidgeted with his hands, looking anywhere but the Doctor's face. “I wasn't hiding, I got lost.”

 

The old man scoffed, almost laughed, until his watch buzzing with a notification interrupted him. The small screen showed Boss coming through the vault doors from the hospital upstairs.

 

Garaki contemplated for a second.

“Come with me, child.” He said, stepping back and holding out his hand.

 

It hopped from the chair, facing Garaki but not taking his hand- holy shit this kid was tall. Or maybe the Doctor was just short… anyway.

“Where are we going?”

 

Garaki grabbed the kid's sleeve, drawing an imaginary string around the boy's wrist and holding the loose end in his hand. “This is your leash. Don't let go.” 

He took an experimental step back, and the child took a step forward, following him as if the string were real. 

 

Garaki smiled, turning towards the door with the Green following close behind. “We're going to see Boss.”

Chapter 4: Meet the Boss

Chapter Text

 

“Who’s Boss?”

 

“He's my Boss, the tall, broody old man that brought you here.”

 

The kid tripped in his way to catch up. “I don't think he was very old looking.”

 

“Oh trust me, he's very old. Older than me.”

 

A gasp. “Older than you???”

 

Garaki pulled up his goggles before rolling his eyes. “Yes, I know I'm old.”

 

“Self awareness is good. How old are you?”

 

This kid… 

“Unimportant. We're here.”

 

Garaki sighed as they got to a tall door. They stopped a few feet away from it as he turned to the child and made a snipping motion over the imaginary string keeping them tethered. “Don't run away now.”

 

The kid nodded. “Okay.”

 

They walked forward and the door slid open, revealing a dark room with bookshelves lining the wall behind a large desk. The room was empty. Just as he heard the child open its mouth to ask another question, Kyudai walked further into the room, behind the desk to a wall that slid open as they approached.

 

The second room was completely dark as they stepped into it. Neither of them said anything for a second, and then, the rustling of fabric and something moved in the corner.

 

“Doctor? I didn't call for you. Has something happened?” A grumbly voice called from the corner.

 

Ahem. “Sir, I found the child.”

 

The man in the corner grumbled, turning away. “Take care of it on your own Kyudai, I believe in you.” The drowsy voice murmured.

 

The doctor huffed, annoyance clear in his tone. “Oh get up. You did not have an exhausting enough day out to go to sleep now.” He reached along the wall before flipping the lights on, blinding everyone for a second.

 

It was a large room, with medical equipment shoved in the back right corner, and the rest of the room set up as a bedroom. There was a corner desk in the front right corner, parallel to a TV/bed setup on the left side. In the bed though, rolled up in a burrito of blankets is the old man the little boy met that day at the market. 

 

The doctor strode to the bed, grabbing the edge of the blanket and tearing it away. He folded it and put it on the desk chair across the room as the other man complained under his breath. 

 

“How indecent of you to wake me up at such an hour as this, you incorrigible old fool.”

 

“It's four in the afternoon dumbass.” 

 

“Yeah, wake up dumbass!”

 

Both men's heads snapped to the doorway where the little boy was standing 

 

“What? Granny said it.”

 

“Do not repeat after me you little rat.”
