One Ope JOKER

Joker: One Operation Joker is the Joker like you've never seen him before…as a single father?!

After a fateful encounter with Batman that results in the Dark Knight de-aging to a baby, Joker takes it upon himself to raise the child into the crusader of justice! But does the Clown Prince of Crime really understand what it means to be Batman—or, more importantly, what it means to raise a baby all by yourself?
