Nightwatch

Ever since he was told he was quirkless Izuky has been training, studying, and learning whatever he could to make up for his lack of quirk. Even after years of being a Hero Izuku still wants nothing more than to be since he promised his parents before they passed away that he would. At the age of 11, he was told he couldn't by his idol, All Might. He had almost taken his life but was saved by Eraserhead who found him and took him home. Before he left Eraserhead had told Izuku that quirk or no quirk he could be a hero. Hearing that Izuku took his words to heart and became a vigilante.

Izuku will have the mutated combination of the byakugan and the sharingan which will be referred to as the byaku-sharingan. He will be part of multiple clans from both parents. He will be OP if I had to rate his strength I wouldn't say he is Kaguya level but I say he is maybe Naruto level or higher in strength. Izuku will have a few different naturally manifested kekkai genkais, all the main nature affinities, many skills, etc. Izuku will be adopted by Nedzu in this story. Izuku will meet a few characters before canon. Izuku will not get One for All in this story. If you don't like this type of story I suggest not reading it.
