Crisis On Infinite Earths: 36 Easter Eggs, Cameos And References You Probably Missed
18. A Shelf Full Of Bat-Rogues (And A Super Friend)
Earth-99's Batman admitted that the world of crime-fighting had driven him so mad that be had killed countless of his enemies in a bid to rid Gotham of them. As a result, he kept trophies on his shelf and, in the process, allowed Crisis to reference some of The Dark Knight's most iconic villains.
The Joker card was obviously a nod to The Joker, the question-marked cane was a reference to The Riddler and the snow globe suggested that he had also put Mr. Freeze on ice.
He also had broken glasses because he killed his earth's version of Superman. Not cool Batman. Not cool.
