Summary: Maxie Zuess is angered over his recent loss in Gotham's most recent election to find the city a new Mayor. Now, Maxie has decided to take control of Gotham City, and only The Batman and Batgirl can stop him.
- SPOILER: The idea of Joker wanting a "Joker Junior" is likely a reference to the movie "Batman Beyond: Return of the Joker". In "Return of the Joker", Joker and Harley Quinn brainwash Tim Drake into being their "child" whom they call "Joker Junior".
- SPOILER: When going over possible schemes, Joker remarks that one plan is "Too Riddler". This same line was used by Joker in the episode of "The New Batman Adventures" titled "Mad Love".
