- Alternative Character Interpretation: The book is built half on this, showcasing many different versions of Batman by many different people. Most of the events that happen in the book can be interpreted in different ways, to boot.
- Ensemble Dark Horse: DCAU Joker is depicted as a completely separate entity sitting next to Harley during the funeral service, and his sole line of dialogue sounds exactly like what you'd expect.Harley: I can't believe he's dead, puddin'.
Joker: Well, I can't believe that he didn't die the first time he dressed up as a giant bat and jumped off the roof.
- Hilarious in Hindsight: Batman is puzzled by Alfred's confession to being the Joker, as he can see the Joker sitting nearby, along with the previous Red Hood. Turns out there's three of them.
- Nightmare Fuel: Alfred's eulogy where he reveals himself to be The Joker.◊ That's right. The villain who crippled, stripped and possibly molested Barbara Gordon, beat up Jason Todd with a crowbar and blew him up before luring a young psychiatrist into a life of violence and cruelty was just Bruce's butler playing a part. Fortunately, all of the villains and victims were just playing a part, too. That assumes, of course that these events even happened in the timeline's story that Alfred was telling.
- Unexpected Character:
- Superman is the only character not part of the Batman Franchise to appear in the story, though he has been inextricable from Batman's history; see: World's Finest.
- Martha Wayne.
