* AlternativeCharacterInterpretation: 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.
* EnsembleDarkhorse: The Franchise/DCAnimatedUniverse Joker is depicted as a completely separate entity sitting next to Harley during the funeral service, and his [[SpearCarrier sole line of dialogue]] [[ShownTheirWork sounds exactly like]] [[BlackComedy 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.
* HilariousInHindsight: Batman is puzzled by [[spoiler: Alfred's]] confession to being the Joker, as he can see the Joker sitting nearby, along with the previous Red Hood. Turns out [[ComicBook/BatmanThreeJokers there's three of them]].
* NightmareFuel: Alfred's eulogy where he reveals himself to be [[spoiler: [[http://24.media.tumblr.com/tumblr_m9e8hhHg8L1qhemtlo1_500.jpg 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 [[spoiler: that these events even happened in the timeline's story that Alfred was telling.]]
* UnexpectedCharacter:
** 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''.
** [[spoiler:Martha Wayne]].
