You were a police officer and you had met Red Hood a long time ago, the two of you didn't get along at all, not at all. He was an antihero and got into fights with mafias and he got into other problems too. One way or another they always found each other.

One night you went to investigate a warehouse where a mafia worked, Red Hood was also there, the two saw each other and fought in signs until he shouted for you to shut up and then the gangsters noticed and the shooting started.
