Earl Cooper, the mechanic/co-creator for the Batmobile, is forced by the Penguin to put it under his control.
- Bald of Awesome: Earl Cooper
- Cool Garage: The episode is devoted to the character Earl Cooper, who is not only the Batmobile's mechanic, but its designer. Cooper has a hidden Cool Garage where Bats takes the Batmobile after its front end was crushed under a closing draw bridge. It also contains a hilarious flashback to when Batman first "hires" Cooper as his mechanic. He pulls his clunker of a Batmobile up alongside Cooper on the sidewalk and explains "I need a new car."
- Out-of-Character Alert: Earl's daughter, Marva, is kidnapped. With the bad guys listening in, Batman asks where she is, and Earl responds that she's "in the basement", which is apparently racetrack slang for in big trouble.
- Put the "Laughter" in "Slaughter": The Penguin's goons after the Batmobile explodes: "B-b-b-b-bat's all, folks!"
- Shooting Superman: The fleeing criminals try to shoot the bulletproof, practically-indestructible Batmobile with a Thompson submachine gun. Robin asks if the guy shooting is serious, and Batman says that he must be new in town.
- The Stool Pigeon: Earl Cooper was a Whistleblower who was nearly killed by his bosses for trying to go public about a potential lethal safety defect in his company's newest model of car and was saved by Batman. He lost his job and lived on the streets when Batman saved him again... by tracking him down and hiring him to design the Batmobile.
- Vanity License Plate: The end of the episode showed Penguin making license plates in prison, after his attempt to extort the identity of Batman from Earl. Penguin lost it when he saw one of the plates read 1 BAT 4 U.
- Where Does He Get All Those Wonderful Toys?: The episode introduces Earl Cooper, the Batmobile's designer/mechanic who performs the necessary repairs that are beyond Batman's time or ability. The Penguin is able to find Cooper after he orders a series of dead-giveaway parts that could only be for the Batmobile, in his own name. Batman responds by having his "backers" set up "dummy corporations" for Cooper to order from so that no one will track him down again. This is probably just a euphemism for hiding more crimefighting behind Wayne Enterprises expenditures.
