    Izuku Yagi, a kid whose dreams were shattered from 4, one who was subjected to neglection by his parents, but this isn't any ordinary Izuku Yagi story, what happens when Izuku recieves a quirk so powerful, but at the cost, of his acquaintance with a huge supervillain, what if, he was turned on by his classmates at the first months, what if, his sister was tried to protect him, what if he kept fighting for the good? Now, at the end of his road, as the power inside him is taking over and erasing his exsistence, as he spends the last moments of his life reminiscing his past, each memorable moment, but what if his exsistence wasn't just erased? What if, it gifted him, a power, to cross between, worlds. Basically a universe hopping green bean, who has the ability to manifest codes to reality, the worlds that he will be visiting are in the tags, but more might be added.

    ¿An Error in Izuku's story? In a world full supernatural abilities where 80% of humanity has those powers called quirks, Izuku Midoriya doesn't have one....or does he? While everyone already has them in the age of 4 his.... file was simply not found. So he grows up, bullied, neglected and abused by everyone around him except his mother. 10 years of abuse, 10 years of pain, But he never lost his smile. He never lost his desire to become a hero. Until one day when he falls asleep he meets someone. Sitting on a throne in front of Izuku was a man, he wore a brown sleevles shirt and black long trousers with gold lines going across them, his left side had pale white skin and his left eye had black sclera and glowing blue eye, his right side had dark black skin his right eye had white sclera and glowing red eye on his pale white hair sat a golden crow with red ruby in the middle. "Why hello there." His echoing voice was so strong that Izuku could feel his supeority just by him speaking. "My name is King Multiverse, tho you should already know that. " Izuku didn't trust his voice so he just shaked his head. King Multiverse raises an eyebrown. "No matter, we need to talk young master." From that night Izuku's life changed. And he promised that he would show them all a true power. The power of Error 404. -I don't own Bnha,Undertale or any of the AUs -Slow uptades -Contains strong language

    (Y/N) (L/N) had an interesting quirk, to say the least. Years of forced training had paid off, but she still felt like she were missing something. However, one thing that was certain was that it was called DETERMINATION - And (Y/N) was very Determined to find it out for herself. ~~~~~~~~~~~~~~~~~~~~~~~~~ This is my first fanfiction and it's fine if want to give me any ideas for where you want the story to go, as I only have the beginning planned out and really don't know where to go from there. Please note I do not own BNHA or Undertale. P.S: Please don't go hating at each other in the comments (if I get any peeps who like meh terrible story). And this will probably only be written on a phone - sooooo expect typos 😅. P.P.S: Also sorry but updates will have long spaces in between.

    What if quirks appeared in real life? ( The world we all live in ) The story focus's on a 14-year-old kid named Ryan who is a sophomore at their high school! Hope you enjoy it! This is the first story I've ever made but I have some amazing ideas for this and I'm very excited to see how this turns out! Im not any crazy good writer so not everything will look perfect but i will try my best! Also I'm going to probably add a few mha characters but not too many since i want this story to be what would happen if it happened in real life to a random kid!

    Ah look, another Undertale x BNHA crossover. In this story, sans always loses to Chara in his never ending battle against her. Then, one day, mysteriously, someone "accidentally" corrupted Chara's SAVE file. Instead of sans being sent to his normal home, he is instead sent to a brand new world, one where heroes and villains exist, and everyone has powers just like him. How will sans cope with the ever setting dread of being stuck here? Is there a way out..? Also, I'm not adding AU sans to this story. Simply put, Ive seen way to many fan stories suddenly shoehorn in AU sans. But if requested I may make an AU with that AU sans instead of classic sans.

    ** Formerly titled "Lebensmüde" ** His world faded to black. All sensation disappeared. The question resonated in his vision. WILL YOU CONTINUE? He reached out with his mind and answered with a yes. EXCELLENT... TRULY... EXCELLENT... ... Izuku didn't ask for this. He was just being a good student and going to get more chalk for the teacher. He didn't ask for the door to close behind him. He didn't ask for Bakugou to send him flying into a shelf. He didn't ask for boxes and boxes of printer paper to fall on top of him. He didn't ask to suffocate on the floor of the supply closet, and he certainly didn't ask to be resuscitated and have to live through the whole thing over and over again, like a recurring nightmare that you can't wake up from. After he finally escaped from that continuous loop of torture, the poor teen found that his life would never be the same. It seemed that he had a quirk, or at the very least some sort of special ability, that had lain dormant up until his death. Well, his first death. There were many, many more to come.
