The Red Hood is an alias used by multiple characters appearing in American comic books published by DC Comics. The identity was first used in the 1951 story line "The Man Behind the Red Hood!", which provides the earliest origin story for the Joker. The storyline depicts an unnamed criminal wearing a red dome-shaped hood who, after a chance encounter with Batman, is disfigured by chemicals and becomes insane, giving birth to his future Joker persona.

The Joker is a supervillain appearing in American comic books published by DC Comics. Created by Bill Finger, Bob Kane, and Jerry Robinson, the character first appeared in the debut issue of the comic book Batman on April 25, 1940. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for his design while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman.
