Waking up naked and in the middle of nowhere was not exactly the best thing that's happened to him, but it wouldn't be the first time. Senku Ishigami was a genius high schooler who ended up leading humanity back from the ground up after the petrification beam turned all of the human race to stone, reviving only 3 700 years after said event, he proceeded to make humanity the top of the food chain once again all through the power of science. And after a series of unfortunate events, he got petrified... Again. And now here he is, once again free after another long 5000 years in a superpowered society where heroes were the norm. But, he has never once been normal anyways. Set to find the science of these quirks, he tackles the world of supernatural with the label of quirkless. With the alias Senku Midoriya, a new hairstyle and a mystery to answer, Senku Ishigami becomes the key to true power. Because if you can breathe fire, then he can make a fire extinguisher. If you can fly, then he can make an airplane. If you have a power called a quirk, then he, as well as all of humanity, has the power called science. [WARNING] My brain: update the fanfics you've already published and try to finish the ones still in your drafts! Me: Alright, I'm sorry but I couldn't help myself, I also have another idea with doctor!Izuku. I was inspired okay!? Anyways, let's hope I can bring Senku's character to justice (and his scientific knowledge because god knows I need more of that). Now on to disclaimers, I do not own BNHA and Dr. STONE, this is a crossover between them (just in case you haven't figured it out yet). If you haven't watched Dr. STONE yet then I recommend you do, not because it will give you further understanding of this fanfic (because this could pass off as smartass Izuku if you wanted) but because it's an awesome anime (and manga), so... Yeah, go do that.
