- Commissioner Gordon
- Mrs. Van Landorpf (Single appearance)
After the Penguin is stopped from stealing the Van Landorpf Emerald and thrown into prison once more by Batman and Robin, he bemoans his misfortune as "the smartest crook in town". This attracts the attention of his new cellmate, the Joker, who mocks his incompetence. The two men quickly develop a rivalry, deciding that Gotham's underworld is not big enough for both of them. Together, they escape prison and agree on a wager: whoever steals the Van Landorpf Emerald has the right to stay in Gotham City.
Upon hearing of the breakout, Batman and Robin cooperate with Mrs. Van Landorpf to set a trap for the two arch-criminals. As predicted, both the Joker's and the Penguin's gang appear at the Van Landorpf house to steal the gem. The Dynamic Duo swoops down to arrest the two men, however, desperation causes the Joker and the Penguin to work together. Though they both fail to steal the emerald, the Joker and the Penguin are able to escape Batman's clutches; more importantly, each now recognizes the other's talents and agrees to a full partnership.
In less than a day, this new alliance buries Gotham under an unprecedented crime spree. When Batman and Robin attempt to capture them again, they are taken captive by a trick from the Penguin and brought to the arch-criminals' shared hideout. Both criminals are ecstatic, but begin to argue again when they cannot agree on how to kill the bound and helpless Dynamic Duo. Batman, taking advantage of their discord and respective egos, dares them into a shooting contest: whoever can hit a vase from twenty-five paces is the superior criminal.
Both the Joker and the Penguin easily accomplish the shot but fail to realize Batman's real goal: getting a jagged vase shard so he and Robin can cut themselves free. Upon being freed, the Dynamic Duo immediately beat the two arch-criminals into submission and arrest them. Furious, the Penguin and the Joker turn on each other once more, each blaming the other for the defeat. As they argue, an amused Batman reassures them that they will never be placed in the same cell again.
