World's Midnight (Male Reader x DCAMU)

When they talk about the L/N, is about the dead rich family, the entire family dead, but one of them survived, Y/N L/N, though he wasn't the same, he escaped the torture, but his younger sister couldn't, in fear and pain he just... disappeared and was considered dead by the entire world. But he hid, hungry and scared, nightmares appeared in his sleeps, real nightmares, scary ones, visions, and what every dream focused, is on this monster, undead and in front of him... that person was him, as some kind of agent of vengeance, a hunter looking for a prey, one that appeared only in Midnight.
