History Characters / IfIOnlyHadAHeart

* AdaptationalIntelligence: Izuku was hardly dumb before, but this fic pushes him into absurd super-genius levels to make up for his disabilities and lack of a Quirk. At seven years old he was at the head of his class, finishing entire textbooks in a day and scoring perfectly on virtually all of his exams (to the point that a single 95 out of a 100 left him in tears). He also developed his own replacement prosthetic arm with a more functional four-fingered hand with an opposable thumb to replace his missing one after finding the one issued by the hospital (which amounts to a barely working appendage with a hook for a hand) with one that responds to his brainwaves with a headband with nothing but scrap parts. He was also fluent in both Japanese and English and was studying German before he met Aizawa. He also is a budding chemist who created darts loaded with his own unique blends of chemicals that can cause things they hit to spontaneously ignite, be shocked, or frozen in a device he calls "The Equalizer". Two years later, he chewed through countless neuroscience papers and books to develop a microtechnological implant that he injected directly into his own spine to directly link a new prosthetic arm he created, which has all of the functionality and fluid movement of a real arm, to his brain. Said implant was so technologically advanced and experimental that no doctor would perform the procedure for him. He also devised his own painkillers to help him deal with the transition process and said arm can be modified easily to accommodate weapons implants or simply his own growth. All of this, again, on a working-class budget and nothing but scraps for parts. He's still in elementary school at this time!
