Weeks passed by since his hospitalization and the revelation of his new power.
And he'd come to know the consequences of possessing such a power and drive.
No, not a drive.
The Need.
The need to Tinker, the need to shape and mold and to create and to -!
"...!" he flinched when he saw an elderly man walk below him in the streets, and immediately, plans and ideas about how to improve the elderly man's spine and cartilages flooded into his mind, making him twitch more than once. His fingers curled as they itched to grab a sharp implement and get to work!
Izuku kept on trying, and he really kept on trying to hold back.
"Is it getting worse?"
Izuku looked up with tired eyes at the gleaming figure of All Might staring down at him worriedly.
He knew better than to say that he was alright, not when it would always show up to bite him in the ass.
"No," he replied with a sigh. "The urge is getting worse."
All Might frowned. "Midoriya-shounen, if it really is too much, then I am sure you and some hospitals should be able to work something out," he replied. "I can vouch for you…"
All Might vouching for him would be great, but what if he failed? He'd already had more than one accident where the urges got the better of him. But with his other powers, not using his power would also be a bad idea. Eventually, the urge would become too much. He would lose his mind and act upon them, twisting some poor person into a monstrosity.
"It's probably for the best," he answered remorsefully.
A hero, Izuku wanted to be.
A crippled and impulsive danger, he'd become.
He gritted his teeth before he followed quickly after All Might to the next crime-in-occurrence.
-VB-
The very next day, Izuku found himself in a local lab with all of the tools he could have possibly needed with meat from various different farm animals. They were all arrayed out before him like a gallery of all the things he could ever need. In fact, tweezers alone were mind-boggling in their variety.
Bonesaw in him was all too giddy and ramped up his Tinker drive into a fugue. He tried to resist the urge to dive in and revel in the materials available to him.
Izuku never had made things while completely in control of himself, but he began to wonder if this was what a master craftsman would feel with the perfect material in front of them. The urge to create sending shivers down the spine and tinkles down the fingers.
His hands reached out.
And then he blinked.
When he opened his eyes, his arms felt tired, he had a cotton ball mouth, his eyes were drooping, his back was slouched, and there was a bloody mess in front of him, literally. He looked around groggily. He looked up to look at the clock, except there was no clock. The clock he had seen before was missing from where it had been. He looked around, only to realize that that there were pieces of the broken clock on the table. He realized that he must have taken it down to use its components for whatever tinkertech he made, and facepalmed. Izuku looked around again, and this time, he finally noticed what he made.
Hanging on the ceiling, an eight legged drone hung looking down at him with … was that a camera?
Izuku looked towards where there should have been a security camera, which was meant to be used by doctors and scientists to observe him indirectly, and saw that one of the four cameras had been ripped away.
He looked back to the camera-spider-drone, and noticed that most of the spider-drone was … organic.
Izuku shivered a little, thinking about how bad it could have been if he had gone into a fugue with a barely living body in front of him. The horrors that would come out of that particular kind of fugue would be … catastrophic.
"I-I guess I'm done?" he said, looking to one of the three remaining cameras.
It didn't take long before someone came through to communicate, though not through the door and only through the announcement speaker.
"{Is that thing safe, Midoriya-san?}" someone asked. Izuku frowned, narrowing his eyes as he tried to remember whose voice that was. Then he remembered that it was Doctor Ichinoya.
Izuku looked to the giant spider drone, and let his power tell him things about him.
Scout, acid spit, surgery aide, voice programmed.
"Um, I think?" he replied. "It's a scout… thingy. But it also spits out acid."
"{I see. I will stay on this side of the wall.}"
Izuku couldn't help the stuttering laughter that escaped his lips.
'They think it's dangerous!' he wailed internally. It didn't help that Doctor Ichinoya had introduced himself before the Tinker fugue as a military contractor.
"I-It's really not dangerous-" he stuttered out before the spider jumped down and landed on the metal table. The force of its landing put dents where its eight legs landed. Then it screeched a bit, sending spittles of acids in the general direction of the announcement speaker. Those spittles landed on the ground, table, and more, and ate away at everything with sizzling hiss.
There was a moment of silence after the
"{I am putting under recommendation that your new power be registered as 'environmentally unfriendly' as well as 'biological hazard.'}"
Izuku turned and glared at his new tinkertech drone. The drone seemed to understand, or at least acknowledge, that it did something bad, and cowered from his gaze, jumping down to the floor - and cracking the floor underneath its legs - and hiding underneath the table. Unfortunately, it was about the size of a really large dog; it really couldn't hide.
He sighed. "Alright, come o-"
The camera-spider-drone-thing came rushing out from underneath the table and jumped him. Surprised by the swiftness of something as big as a dog, Izuku yelped as it glomped him with its eight legs and licked his face with its acid-dripping tongue.
…
But it didn't burn.
His power was quick to provide the answer.
Surgery aide. Can act as narrow space tunneler and rescuer. "It's … a rescue unit?" Izuku said out loud in surprise.
"{Can you repeat that, Midoriya-san?}" Dr. Ichinoya asked.
"It's a rescue unit," he repeated. "The acid doesn't hurt human flesh. Wait, then why is it a surgery aide?"
Bonesaw was quick to respond.
The front two legs have hidden blades within to cut and hold human flesh while another more medically inclined human works on fixing issue at hand. Voice programmed to help guide the cutting and holding of human flesh. Can perform emergency first-aid treatment.
But Tattletale was also quick to point out issues.
[The drone cannot differentiate commands unless upgraded to include voice recognition system either organically or digitally. It would allow for malevolent individuals to give it bad commands.]
"Ah. Apparently, it can also help with one-man surgeries. Its two forelegs have surgical blades and grapplers to help with emergency surgeries, and it even has its own disinfectants. It can also understand human speech to a degree, making it on par with rescue animals as well, but one that can do more than just find disaster victims but also perform on-spot emergency treatments. It would be useful in any rescue missions where the number of personnel involved are limited, and each medical personnel might be forced to work alone. You can also use this unit to burrow into narrow spaces. It's actually made for that kind of work where normal humans would have a hard time moving-"
"{How much would it cost you to make one of these?}"
Izuku startled out of his muttering analysis. "H-huh?" he uttered incoherently.
"{If half of what you stated was true, then having these on stock to use for future emergencies will be great. Of course, I expect tests will be performed to ensure that it is safe to use and can -}"
"{Dr. Ichinoya, you know that the military won't find much use out of Midoriya-kun's drones. I think hero agencies should be given priority because it is the heroes who encounter more disasters than the military.}"
That was a new person that Izuku didn't recognize. Unlike Dr. Ichinoya's military disciplined direct and formal method of speech, this new voice was a little bit nasally and smug. It was the voice that Izuku expected to hear from someone advocating for the removal of hero influence or less oversight from the government, and yet here was this voice, suggesting that a new hardware should be supplied to heroes first rather than the military.
There was a prolonged pause after that.
[They're arguing over who should have the first dibs on buying your drone,] Tattletale droned on.
Izuku frowned. 'I guess I better start on the voice recognition system…' he thought to himself. 'I think an organ will do better.'
-VB-
By the time they finally contacted him after arguing over themselves, Izuku finished a prototype auditory organ, installed it, and voice programmed a rudimentary command software using components from another camera he broke apart.
"{Midoryia-san.}" It was Dr. Ichinoya again.
[Doctor Ichinoya won the argument. The military will be granted permission to buy the first hundred units.]
Huh.
"Yes?" he asked.
"How many can you make if we provide you all of the materials?"
Izuku tittered with the answer for a moment. Tinkertech wasn't something he could replicate readily, and tinkertech needed a lot of maintenance. Should he just say that?
… He should.
"B-But my tech requires a lot of maintenance and it's hard to replicate…"
That brought about a pause.
"{What do you mean?}" someone else asked through the speaker.
"My power is…" Izuku explained it.
Hours later, he was on his way out of the hospital lab with his new pet(?) with no contracts forced upon him by either hero agencies or the military. The two institutions considered the inability to mass produce his tinkertech a bad thing.
Izuku was just happy to get away from the hungry hyenas.
All Might was glad, after he heard about how everyone had bickered over who would get a piece of Izuku, that no one got him.
"So what are you going to do with it now?" All Might asked him while the two of them had a moment of peace. Now that Izuku's tinker itch had been settled, they had gone back to their ordinary routine of arresting criminals and helping regular citizens.
Izuku blinked and then stared down at his pet(?).
"I think I'm going to name it."
"It's going to be your pet?" All Might deadpanned.
"I read that people had tigers for pets, too."
"But those are tigers. They are exotic."
"My Brain Spider is exotic too!" Izuku snipped before he snapped his mouth shut. He meant to say 'spider drone' but Bonesaw decided to intervene, pushing everything it had for a split second to force those words out.
"... Brain spider?"
All Might looked rather pale.
Izuku realized what a "brain spider" might sound like.
And then he had ideas…
'Damn it, Bonesaw! Stop it!'
And so the days continued with Izuku completely unaware of the fact that there was a bear-mouse-thing that wanted Izuku's help with his school...
