Intelligence Boost! E=mc² (Brotherhood)

AN: Rewritten Chapter (10/21/2023)

Chapter 3: Intelligence Boost! E=mc²

The overload on my small brain caused me to go unconscious for a few minutes before I was taken to the hospital where a sleepy doctor would run some tests on me.

"...Normally Quirks awaken from the age of four, however, a premature awakening is not uncommon, as is the case with your son." The doctor monotonously explains to Inko before yawning.

"Has my baby awakened his quirk? But I would have noticed if he..." She asks confused and shocked before the sleepy doctor interrupts her ramblings.

"Quirks can manifest themselves in different ways, children can develop mutations related to their parents' quirks or simply have no relationship with them... It all depends on the genetic lottery." He explains, waving his hand dismissively. "Have you noticed anything unusual about his son lately?"

"Well, he has always been a very intelligent and courteous child... He said his first word at 6 months and also learned to go to the bathroom on his own before he was 2 years old." Inko explains proudly before she is quickly interrupted by me.

"Mom!" I quickly exclaim in embarrassment as my cheeks blush lightly. That information is irrelevant! Irrelevant!

At this, the sleepy doctor snorts and focuses his attention on me. "Has the headache gone? How do you feel?" He asks, ready to write down my answers in the medical report.

"My head doesn't hurt anymore and I... How do I explain it? Heh... Do I feel a little smarter than before? Maybe." I respond with apparent confusion while scratching my head innocently.

"Possibly an intelligence boost, that could explain the headache." He murmurs monotonously, jotting down a few things in the report before yawning again. "My shift will end soon, so I'll run some routine tests on you to determine the status of your Quirk and your cognitive ability..."

"...Please answer honestly."

"Of course!"

The next day.

"Small Intelligence Boost?" Bakugo mutters, holding my recent Quirk ID record in his hands.

"Hah! So your quirk isn't as amazing as mine!" He exclaims, letting out an obvious sigh of relief. The little idiot was actually afraid that my quirk was better than his. "But, I guess with your brain you should be able to run my hero agency in the future." He declares, bragging and giving me a firm pat on the back.

"Don't say those things Kacchan, my little brother can still become a cool hero... There are many heroes who use cunning and gadgets to capture villains like Eraser Head or Sir Nighteye." Izuku quickly intervenes, grabbing my right arm and trying to pull me away from Bakugo.

"His ID says that he can only use his quirk for a short period of time before suffering headaches... So it's my duty to teach him how to fight!" Bakugo exclaims, grabbing my left arm before he and Izuku exchange a rivalry look as if they were shooting lightning bolts at each other.

Then the idiots started pulling me by my arms...

"I'll teach him to fight!"

"I'll teach him to analyze heroes and quirks!"

"Stop, you're hurting him!"

They exclaim in unison before their eyes widen in surprise and release me instantly. At least they have some common sense.

A few hours later in the privacy of my room.

"Small Intelligence Boost..." I hum, staring intently at my Quirk ID record as a small crooked smile spreads across my face.

I won't let anyone take advantage of my quirk except me!

If the Hero Public Safety Commission finds out about my quirk's true capabilities, they will do whatever it takes to wrap their claws around me.

Not to mention that All For One and Nezu would definitely take an interest in me... Whether to manipulate me or study my brain.

However, in the eyes of society, I am just an ordinary child with a small boost of intelligence that makes me a little smarter than other children my age...

...And no one would be able to suspect that behind my innocent smile hides the mastermind of what is to come... Whether for better or worse.

3 months later.

The night in the city is dark and stormy, the vast majority of the inhabitants sleep peacefully without having any idea of the dangers that lurk in the shadows of the dark streets of the city of Musutafu.

It's a perfect night to test some of my latest and possibly dangerous gadgets in a controlled environment... So I'll use some guinea pigs while I enjoy the show and gather information.

"Field test #5 begins."

I hum happily, pressing a sequence of keys on my apparent toy laptop... Which has been subtly programmed by me to perform more complex actions. So I continue pressing a careful combination of keys until finally, I press the key with the picture of a train.

🚆 "The train goes Choo~Choo!" 🚆

My toy laptop announces childishly as I hack into the security cameras in the area and infiltrate the depths of my target's cybernet.

☆ *** Security Breach! *** ☆

*** Remote access to ATM B-422... Executing commands.... ***

*** Full Access Granted! ***

My Quirk really is terrifying and fantastic.

"That message on our phones was real! This will definitely be our biggest robbery!" Guinea Pig #1 exclaims in shock, as the ATM I hacked rains money on him and his small group of accomplices.

They have taken the bait.

"Quickly, let's take all the money we can and get out of here!" Guinea Pig #2 exclaims nervously, quickly picking up as much money as he can off the ground as a deranged grin spreads across his face.

"This is too easy... Something is not right." Guinea Pig #3 murmurs suspiciously, focusing his attention on a curious stuffed bear lying on the floor next to the ATM.

At this, the teddy bear's chilling red eyes light up, as I activate the intercom hidden inside. "Exactly, Superstar!" I exclaim in a slightly robotic and childlike tone thanks to a small tweak to the intercom as their shocked gazes quickly focus on the teddy bear.

"In exchange for this wonderful loot, you have all become my guinea pigs! That is why you guys must try my toys or you'll go to jail! It's the law of equivalent exchange!" I exclaim happily as they tense up.

"This isn't a fucking game!" Guinea Pig #3 exclaims angrily, forcefully kicking the teddy bear into a nearby wall.

"Oh really?" I hum as a parachute box descends in front of them... Inside the box were three very peculiar gadgets. "By the way, the police will arrive in 3... 2..." I turn off the intercom as the teddy bear's eyes return to normal.

Immediately afterward, the sound of police sirens in the distance alerts my guinea pigs before a pair of police cruisers turn a corner and come into view.

All this while my guinea pigs proceed to grab the gadgets from inside the box with completely panicked looks on their faces. After all, they are ex-convicts whose quirks are not suitable for combat... The result was obvious to me from the beginning.

Show time.

"Unit 15 reporting, suspects are in sight."

"Copied, unit 16 will be behind you... Proceed with caution the anonymous call mentioned that these guys had chaos weapons... Whatever that means."

A small toy radio strapped to my belt tunes in to some of the police radio transmissions not far from my position while I eat popcorn and observe the situation with interest from the top of a building.

"I'm not going back to jail!" Guinea Pig #3 exclaims completely angrily, holding one of my weapon prototypes in his hands before pointing it at the police patrol and pulling the trigger.

"What the hell is that?!"

"Unit 15 get out of the way!"

Then an incredible explosion of confetti hits the first police car hard, shattering the driver's window and causing him to lose control of the vehicle before crashing into a light pole.

"This is incredible!" Guinea Pig #3 exclaims with a vicious smile, now pointing at the remaining patrol. "I feel so...!" It's all he can exclaim before the gun fails and explodes in his hands, engulfing him in an explosion of confetti and causing him to fall to the ground unconscious with some painful burns.

Prototype R-004 Failure after the first shot... Possible overheating.

"We have to get away from here at any cost!" Guinea Pig #2 exclaims in panic, quickly putting on some boxing gloves with no other options as the remaining police cruiser comes to an abrupt stop in front of him before a pair of police officers quickly descend from the vehicle holding their police batons tightly.

"Die!" Guinea Pig #2 exclaims, pressing a button and activating my weapon prototype, causing an electrical current to epically envelop his boxing gloves before charging towards the police officers with a loud battle cry.

Immediately afterward, a police baton crashes hard into his stomach, leaving him breathless as he falls to the ground. "Surrender villain!" The police officer responsible for that exclaims, swinging his police baton in the air before suddenly a current of electricity spreads from his right leg to his entire body.

"I caught you." Guinea Pig #2 whispers ominously, holding his opponent's leg tightly before a short circuit causes him to be affected by the electricity as well.

⚡️ "AHHHHH!" ⚡️

Those affected exclaim in unison before the batteries that powered the rudimentary power source run out and they are left unconscious under the horrified gaze of Guinea Pig #1 and the remaining police officer.

Prototype H-001 Overloaded... The poor quality of materials severely affects performance.

"Don't try anything strange!" The remaining police officer exclaims in alarm, drawing his weapon as his breathing becomes erratic.

"Damn!" Guinea Pig #1 exclaims, forcefully kicking a strange soccer ball towards the police officer, causing this prototype to burst into smoke, quickly engulfing the entire area in thick white smoke.

"This is my chance... I must escape... Cough, cough..." He begins to cough violently along with the police officer before eventually, the indisputable sound of two bodies hitting the concrete reaches my ears.

Prototype K-007 Successful failure... The chemical combination of the smoke still needs to be refined to avoid poisoning and unconsciousness. A gas mask will be very useful to me in the future.

"Field Test #5 ends!"

I exclaim happily, satisfied with the results obtained as I put my toy laptop in my backpack and begin to return home. It would be really troublesome if Inko or Izuku found out that I sneaked out of my room window.

I still have many things to improve and implement in future prototypes, but good quality material is a frustrating limitation. Until now, most of my prototypes have been built with scrap metal that I found on Dagobah Beach.

If I really want to implement my most complex plans, I need a lot of money... An amount that is simply impossible for a child to reach without raising suspicions.

I need connections... But I have to be very careful, one wrong step and everything will end very badly.

The future will definitely be fantastic!

"Hahaha!"

POV Third person.

A couple of hours later at the police station.

Police Detective Naomasa Tsukauchi was tired and very frustrated, pacing back and forth in his office while some of his subordinates watched him worriedly from a distance.

"It was supposed to be a perfect, peaceful night... I had just finished my paperwork and was ready to return home where I planned to sleep peacefully for a few hours. But everything fell apart because of that mysterious anonymous call." He mutters irritably as he focuses his attention on a new and enormous mountain of paperwork piled up on his desk.

"Tamakawa, do we have new information regarding the origin of the anonymous call?" He asks, focusing his gaze now on his loyal subordinate Sansa Tamakawa, who lies obediently by the door to his office holding a curious teddy bear as part of the evidence.

"It was impossible to determine the origin of the call, detective. However, it appears that the call gave notice of the ATM robbery even minutes before it occurred." Tamakawa murmurs with a slight hint of concern before a serious expression spreads across his feline face. "It was premeditated."

"I thought so." Naomasa huffs as he tries to tie up the loose ends. "As a result, a police patrol was rendered inoperative, three police officers were injured, and the small-time villains responsible were no better off." He murmurs, approaching the window with his hands behind his back as he gazes at the seemingly peaceful night sky of the city.

"Detective, I must highlight that the strange weapons found at the crime scene appear to have been handcrafted while the security cameras in the area only captured static." Tamakawa says calmly as he comes to an inevitable conclusion. "This just means that..."

"It means we'll need more coffee."

Naomasa states seriously as a sinking feeling spreads throughout his body. "The masterminds of a crime who hide their tracks very well always tend to be the most dangerous."

Without anyone noticing, the red eyes of the teddy bear in Tamakawa's hands glowed menacingly for a small fraction of a second.

A few days later, a newly formed company called Cognito Inc. launched a video game for sale in the main application stores of many electronic devices, taking children, young people, and some adults by surprise.

After all, it was something never seen before in this world... Therefore, the success of the video game was immediate.

Meanwhile, inside a gloomy bar, Kurogiri watched his young master with concern...

"HAAA!" Tomura Shigaraki exclaims in alarm, dissolving another gamepad in his hands as his heart beats rapidly. "Damn... This time the energy ran out and that thing killed me." He mutters quickly as a crooked smile spreads across his face, staring at a static-filled screen in front of him.

"Maybe if I buy all the limited edition items in the store..." He mutters reflexively, scratching his neck in frustration before his eyes light up. "Kurogiri, I need another gamepad and one of Sensei's credit cards!"

"Young Shigaraki, I think you should get some rest... That strange game seems to be affecting you..." Kurogiri intervenes politely before being interrupted by Tomura.

"Shut up, Kurogiri, you wouldn't understand! But this video game is art! ART!" Tomura exclaims with a vicious grin before a determined look spreads across his face.

"Kurogiri, don't interfere and give him everything he wants... It's the first time I've felt his determination burn like this." A thick voice hummed with interest through a small transmitter next to Kurogiri. "Let's consider this as part of his training."

"Definitely... I will definitely survive the fifth night!"

The name of the video game was... Five Nights at Freddy's.

"The fundraising for my evil plans is progressing satisfactorily as estimated." Isamu Midoriya hums happily, watching in fascination as the number of sales increases. "But this is only the beginning."

"The bait has been placed."
