Class 1-A has known each other since the age of four. All of them except for Shoka and Koda bullied Izuku because they wanted to protect him due to the fact that he doesn't have a quirk. One day, he was running away from them and discovered his true father and decide to train everyday in order to become a great hero. What Izuku doesn't realize is that the Mishima's enemies, Azazel and Ogre, were revived by AFO and ready to take revenge on the Mishimas. Will Izuku succeed all the while his old life is trying to get his forgiveness or will he fall? You'll have to find out.

Inspired by @Natsu145's story from The DekuVerse.

after being neglected by his parents and bullied by his sister and her friends on a physical and mental level our boy let's just say finds something he should've find in the forest that could be everyone's doomsday

Izuku had an unfair life. He was dealt with a bad hand. Ever since he was announced to be quirkless, everyone treated him like dirt. To make things worst, he lives in a population where only women can have quirks. Since then, he was beaten, abused, neglected, bullied, and raped by women. One day, his 'family' and 'friends' decide to get rid of him. What do they do? Shoot him? No that's the easy way out. Sell him to females for experimentations? You wish. How about using their quirks and beating him so severely that he lost his voice and any feeling to his legs or arms. After that, they decide to throw off a cliff and into a 'tar pit'. Leaving him for dead. Hoping that he'll burn in hell. However, what they didn't realize is that they threw him in a black puddle and not a 'tar pit'. While Izuku was 'dying', he replays everything that happened to him throughout his life and wants nothing more, but the destruction of humanity and remaking the world into his own image. He then arose from the black puddle in a new appearance.
