Disclaimer: I do not own neither Mha or Ninjago. Izuku Yagi before the age of 4 was an ordinary kid with loving psrents and an awsome twin sister, until they went for their quirk check where Izuku's sister Izumi got a good quirk being able to enhance her strength kinda like her father, but Izuku was classified as quirkless, so when they got home Inko told Toshinori the whole prediciment and Toshnori tried to encourage Izuku but it was to an avail Izuku would still try to be a hero, but the next day Izumi telling her friends about Izuku being quirkless and him still trying to be a hero, so they came up with the idea to bully him to stop him from becoming a hero but will later regret it.
