Tropes:
- Badass Boast: When a judge declares him mentally competent to serve a prison sentence, Croc responds with this:Killer Croc: Competent? Competent? That's an insult, you old bag of gas! I'm not just competent... I'M AS GOOD AS IT GETS!
- Bittersweet Ending: Batman and Batgirl save the day and the villains are defeated, but things still end tragically for Baby-Doll. Croc made a fool of her, and her fantasy was shattered again, leaving her with nothing but an incurable condition and more jail time.Baby-Doll: [crying her eyes out] You shouldn't have done it, Crockie. You shouldn't have made Baby angry. We could've been so happy. And lived happily ever after. Just like on TV.
- Brains and Brawn: Baby acting as the brains to Croc's brawn.
- Clingy Jealous Girl: Baby for Killer Croc.
- Driven to Suicide: After finding out Croc was using her, Baby-Doll plans to blow up Gotham, taking Croc and herself with it.
- Exact Words: Baby says her plan to sabotage the nuclear plant will keep her and Croc warm "forever and ever." Considering she plans on having them both be incinerated in a radioactive fireball, she wasn't exactly lying.
- Girlish Pigtails: Part of Baby-Doll's redesign. It makes her look a lot like Angelica.
- Hate Sink: Killer Croc is at his most loathsome in this episode, stringing along Baby Doll, pretending to care for her and buying into her "kindred spirits" sentiment, just to use her as an edge in committing crimes.
- Hero of Another Story: As the Daily Planet says, "Superman Has Hands Full."
- Hot Skitty-on-Wailord Action: Batgirl wonders what Killer Croc and Baby-Doll do during a date. Batman DOES NOT want to think about it.
- Instant Sedation: Both played straight and subverted. The shot Batman gives Croc after his first escape attempt puts him down pretty fast, but the one Baby-Doll gives him in the final fight doesn't. Possibly justified in that the latter is administered to his ankle and would thus take longer to circulate into his system.
- It Will Never Catch On: Killer Croc reveals a newspaper with Bruce Timm's picture on the front, along with the headline "B.T. Quotes: DVD the Next 8-Track." That's a swing and a BIG miss there.
- Just Between You and Me: Croc admits to some floozy that he doesn't love Baby-Doll and is just using her, unaware that she's listening.
- Know When to Fold 'Em: Much like her last episode, Baby-Doll knows when to give up when the odds are against her.
- Laser-Guided Karma: The one tourist who recognizes Mary Dahl doesn't stop pestering her about her old acting gig and her criminal history (not to mention technically assaulting her when he grabs her hair), so she slams his head into her book.
- Mad Love: Croc is obviously just using Baby-Doll from the beginning, and if he does feel anything for her, it's merely pity. At least Baby-Doll catches on quicker than Harley that her feelings are unrequited, but she's so eager to feed her delusion that it still takes some time.
- Mr. Exposition: The rude tourist at the beginning of the episode serves this role, summing up Baby Doll's backstory for the audience.
- Not So Stoic: See Hot Skitty-on-Wailord Action above. Batman, who has fought mobsters, psychos, eco-terrorists, schizos, immortals, and mad scientists, is Squicked out by the thought of what Baby-Doll and Croc do when not committing crimes.
- Outlaw Couple: Croc may be uncomfortable with the "couple" part, but they do quite a few jobs together.
- Prim and Proper Bun: Baby has one when she's trying to look grown-up. It fails miserably.
- Psychopathic Womanchild: Baby speaks like this for the majority of the time she spends working with Croc. Only in the first act when she's still trying to be seen as an adult does she talk normally.
- Playing the Victim Card: Killer Croc tries to gain sympathy from the court by claiming that he's a victim of prejudice based on his appearance. However, after letting him have his say, the Judge decides that Croc is competent enough to stand trial.Judge: Have you anything to say before I pass judgment?
Killer Croc: Yeah. I'm a victim of prejudice. Look at me. Nobody understands how rough my life's been, just 'cause I'm... different.
Judge: Nevertheless, it is the judgment of this court that you, Killer Croc, are competent to stand trial for murder in the first degree. Court is adjourned. - Superman Stays Out of Gotham: Justified by one of the newspapers describing Croc and Baby-Doll's crime spree — a side headline in the Daily Planet says "Superman Has Hands Full."
- Trademark Favorite Food: Killer Croc loves raw chicken. He happily scarfs down the ones Baby-Doll feeds him while visiting him in prison, and later, while raiding the fridge in their hideout, Croc looks up with a chicken already in his mouth.
- Villainous Rescue: Baby-Doll saves Batman from being thrown by Croc into a Deadly Rotary Fan as thanks for him rescuing her from the same fate.
- Woman Scorned: Baby-Doll does not take being used well.
- Worst News Judgement Ever: Would Baby-Doll and Killer Croc’s crime spree really make the front page of another city’s newspaper?
