Izuku Midoriya: Under the Red Hood

During a hostage situation gone awry, nine-year-old Izuku Midoriya is caught in the crossfire of the battle between the police, professional heroes, and the infamous supervillain, Lazarus. With the emitter quirk 'Missing,' Lazarus has the uncanny ability of somehow making whomever he touches disappear for the span of one week. Thus far, no one has been able to determine where these people have gone or how they were able to return, including those his quirk has affected. This is due to the fact that, upon returning, his victims have gone mad -- foaming at the mouth, attacking the people around them, and a few have even had seizures. After a few years, though, these people recover but without the memories Lazarus had instilled. Midoriya, though -- Midoriya was different. He recovered, and he remembered.

This is a work inspired by @SilvermistAnimeLover's 'A Robin's Nest' on Wattpad and Archive Our Own.
