  • "A Dark Knight: Mandatory Brunch Meeting"
  • "A Dark Knight: That's Entertainment"


  • "A Legion of Horribles" was the title of the penultimate episode of season 2.
  • Season 4 loosely adapts Batman: Year One and The Long Halloween. Cameron Monaghan hinted on Twitter that the Legion of Horribles serves as an homage to the villainous roster from The Long Halloween, composed of the Joker, Penguin, Catwoman, Scarecrow, Solomon Grundy, Mad Hatter, and Poison Ivy. Most of these villains notably appeared as members of the Legion.
  • The name of the group seems to be an allusion to the group the Legion of Doom.
