"well fuck. When I said I wanted to be reincarnated into Mha I didn't indicate that I wanted to be the main character" Midoriya muttered while checking himself in a mirror after he had just woken up from a car drive from the quirk hospital. But it turned out that this version of Izuku Midoriya died of heartache when he found out that he had no quirk.
That's how our MC found himself in this dangerous situation. But it wasn't without its benefits as he had gotten great boons in the form of quirks but only one of them was confidential to his mother's quirk.
His first quirk was smooth processing; which allowed him to think clearly no matter how much pressure was placed on him.
The second was hyper intelligence: which made him one of the smartest persons in the world. But also increased if he meets someone smarter than him.
The third was polarity: which allowed him to attract or repulse anything and anyone.
While the last was analytic: which meant he was extremely observant to the slightest details in anything, which often caused him to want to dissect the object of his attention. But he mostly used it to notice mechanical errors in his equipment and correct them to their full perfection.
"Izuku darling do you want us to go get your favourite ice cream? You can buy as much as you want this time" his mother, Inko Midoriya said with a soothing voice in an attempt to cheer him up. "Thanks, Mom, but I just want to go home if that's okay" he replied in a quiet but clear voice.

Ever since he had been tested quickness his mom had been stress eating which made her gain weight, but after seeing Midoriya getting fit and working hard even though he 'didn't' have any 'quirk', encouraged her to stop feeling bad for him being quirkless.
He even started requesting her to buy some supplies, components, chemicals, and circuits from a few stores that caught his interest. Then he asked her to help him purchase a small workshop across the street, then started tinkering with them which led to a few blackouts, electric shocks, and explosions which led to a lot of scolding from his mother. But after those few times, it happened less frequently till it stopped. He did get some good results out of the explosions and blackouts. Like the air shoes he made which gave him little to no friction when he wore them and also increased his relative sprinting speed which he tested out in the relatively Spacey workshop that held scrap and masterpieces alike.
He also managed to recreate the octo suit that doc-oc wore during the Spider-Verse movie( I chose them because they were retractable and looked more biomechanical than the Tobey Maguire movie) he also implanted a neural transmitter chip in his brain to Control any equipment he ever creates and to suppress the adaptive a.i in the octo-suit which he was currently wearing at the moment and using the extra appendages to lift, mix, weld and type while he was busy cold forging a few body pieces for a new project lineup called "team metal" which is a co-project to "sega blue"(it only consists of a few sonic characters) which was the biological versions of "team metal" even though they are currently still embryos.
When Midoriya was done cold forging all the necessary parts and was sure the computer coding was correct he began packing up and heading home, most of the work was done by the tentacles. Upon entering he noticed a letter on the table beside a lunchbox. 'Hello Izuku I will be out for a while, I went shopping for some more groceries and pay a few bills so don't wait' After reading the letter he smiled a bit before opening the lunchbox and began to eat the contents. After the meal and a nice cold shower, he sat in front of the tv screen with a slightly bored expression while flipping through the tv but stopped a nanosecond later on a channel that was advertising some sort of science fair convention for the best invention and the best inventor gets to go on a one month, all expense paid trip to i-island.
Right then and there Midoriya thought to himself 'we'll that's new, I guess I could show off to the noobs that want to participate then probably mess with them anyways, I'm pretty bored nowadays' before sending a tentacle to grab the phone on the kitchen counter before sailing the number he had memorized and answering a few questions about atoms and elements and chemical reaction before he finally got registered
