Harley Quinn Wiki

No wonder your dad don't remember your birthday.
— Arkham Asylum Prison Guard

Joey Day is the son of Julian and Debbie Day. He loves his father despite him being a supervillain and not being able to remember his birthday.

After his father gets committed to Arkham, Joey and his mother go to visit him. Joey tries to give his father a cactus as a gift, but the guards knock it out of his hands and incinerate it.

They then call him a moron for bringing a plant to Arkham when Poison Ivy is still there, causing him to break out into tears.


Joey Day has what is likely the most generic appearance of any character in the entire show, light brown hair, the bangs of which are swept to one side of his forehead, pale skin, brown eyes which match his hair, and a light red t-shirt with a darker red collar.
