- "This happens at Halloween. Your imagination runs wild. Remember last year you didn't want to trick-or-treat 'cause you were afraid of the monsters?"
- —Daryl on Halloween[src]
Established at some point, the celebration of Halloween includes traditions such as trick-or-treating, costume play, house decorations, pumpkin carving, and parties. On Earth-1, the holiday in a modern sense was a common knowledge as early as the late 1920s and early 1930s, with Al Capone referencing it in regards of costume play in 1931.
In 2014, John Constantine was in Alabama around Halloween exorcising the spirit of Marcello Panetti from Henry, who had destroyed the pumpkins his mother was about to carve for the celebration and was dressed in a dead man costume for the celebration. The successful exorcism trip culminated in John observing the children trick-or-treating while lying on his car, drinking beer and smoking.
In 2019, Ramsey Rosso began attacking the people of Central City aand turning them into Blood Brothers around Halloween. He had a brief confrontation with Flash and Frost, but he managed to escape.
