Just how bad could it be if one small change was added to Izuku Midoriya? 

When suffocated by the Sludge Villain years ago, an impairment of the area in his brain that produces 5% of the body's serotonin* occurred. He's placed on medication to ease the symptoms of his condition, Serotonin Deficiency, though not much comes from it. Energy-depleting side effects, overwhelming amounts of pressure, and shortening limits gnaw away at his potential and mental health. 

Though, that's not the only thing that aims to turn everything upside down. One day, a man puts a package in Inko's hands, requesting it to be given to her son. Once the contents and the sender become a reoccurring mystery, questions and questions pile up, and life begins draining like sand through Izuku's fingers. Head aching and hope running dry, it's only a matter of time before things quickly cross the line, and turning back is no longer an option.


*Serotonin is a chemical responsible for controlling mood, attention, sleep, and pain. (5% of which produced in your brain.)

WARNING: Viewer discretion advised. This story contains descriptions of murder, suicide, sex, and other mature content. Spoilers also ahead. ~~ What if Deku wasn't born quirkless? What if the reason for Katsuki's hurtful words had to do with the dark past Inko desperately tried to keep hidden from the outside world? What if becoming a hero wasn't the answer after all? ~~ My eyes widen. "I've decided. Young man, you will inherit my quirk." I let out a sigh of relief, laying down on the ground as my anxiety fades. I'm overwhelmed with joy, tears streaming down my face as my body is overcome with brutal exhaustion. I don't plan on using this power to become a hero, but All Might doesn't need to know that. I can't think of being a hero, or anything else for now. I need to get stronger, even stronger than my father. Wait for me mom, Kacchan, I'm coming. ~~ After that night, things only became harder for Izuku. The mental pressure was too much, to the extent that it took an unhealthy turn. Izuku could barely handle the pressure of having no one to rely on, torn between becoming a hero and being taught how to assassinate by the killer of heroes. It wasn't long before his sanity began to split. ~~ "It's okay. Honestly, you're the first person I've met who doesn't think my quirk is more suited to become a villain.." Shinsou said. After spending so much time with villains, I no longer thought of the word the same. "If you ask villains their story, you'll probably think they'd make pretty good protagonists. We always see things from the hero's perspective but we rarely ask how the villain ended up the way they are. The heroes are the real villains if you ask any villain, and even villains can be a hero to someone." ~~ I killed someone. I know he deserved it, yet I still couldn't look down at my own hands the same. Dried blood covered the bandages I wore around my wrists when I train with Stain. I had no choice but to accept it. I became a hero killer.

What if, when Bakugo and Midoriya are older and hero's, one of them doesn't make it back from their mission as they thought they would. Bakugo and Midoriya had went out to help a couple other pro hero's. You may know them as Denki Kaminari (Charge Bolt) and Kirishima Eijiro (Red Riot). They were up against a villain who constantly enhanced his quirk the longer it took them to take him down but it wasn't as easy as it sounded. Besides this villain, there were others. Civilians he'd turned mad and forced them to use their quirks on the four boys. They couldn't hurt to civilians. They're innocent. But the villain, Madane, wasn't letting up and Dynamite was running out of stamina. An unknown blast was mere inches away from shooting Dynamite and, the number one pro hero, Deku, had jumped and pushed him out of the way just in time. Instead of it hitting Bakugo, it hit Midoriya. Right in the heart.. Will Deku fall from his number 1 throne, or will someone help him just in time?... And if he survives how will this villain be defeated? It all would crumble, and maybe fall into place. But maybe...it would fall into disparity. A Bakudeku Story. {Warning, there's mentions of types of mental illnesses and even seizures. You are warned.} ^but if you're in for heartbreak, then have a blast, my guy. [notice] The art in the photo isn't mine, and I give all credits to the art's magnificent artist and their talents. I also do not own these characters. They belong to Horikoshi who made the My Hero Academia Universe. I once wrote a BakuDeku story called "Why Am I Still Here". That was when I was much younger. My grammar has improved since then. I thank you all for any support. Don't be shy! Comment!!!

Izuku Midoriya was bullied and looked upon as a waste of space for the majority of his life. It only got worse when everyone found out that he was quirkless. From then on the kind-hearted soul started to turn dark. He was given a chance to redeem himself and with this chance he plans to make Bakugo suffer the same way he made him suffer. This is basically a "what if" story of what would have happened if Izuku had never talked to All Might. This story progresses kind of slowly so it's going to be a bit long. Will contain themes like suicide, depression, gore, etc. Read at your own risk!!! Nothing belongs to me except the plot. So enjoy~
