Joker's Asylum provides examples of:
- Alliterative Name: Two-Face's story has him meet a volunteer firefighter named Holman Hunt, who is similarly disfigured on one side of his face.
- The Bad Guy Wins: Poison Ivy's story ends with Batman failing to prevent her from killing the last of the land developers she had been targeting in retribution for the harm they caused the environment.
- Between My Legs: Harley Quinn's story has a panel where we see police cars driving towards Harley and the perspective is between her legs.
- "Blackmail" Is Such an Ugly Word: In the Riddler's story, he states that he prefers the term "acquiring" to "stealing".
- Driven to Suicide:
- The sad ending to Two-Face's tale, should the reader's coin flip come up tails, ends with Holman Hunt shooting himself after his wife leaves him.
- In Penguin's tale, the chef who the Penguin was terrorising was hanged himself in a gas station restroom.
- Earn Your Happy Ending: The happy ending to Two-Face's tale, should the reader's coin flip come up heads, ends with Holman Hunt reconciling with his wife and their relationship recovering from Two-Face's attempt at manipulating him.
- Evil Is Petty: The Penguin reacts to a chef laughing by getting the restaurant closed, deporting his girlfriend, planting child porn on his best friend, destroying the church and park he visited, driving back to alcoholism and getting him an annoying neighbour who blasts heavy metal music all the time. Other examples of Oswald being a dick include having a starlet disfigured, cutting a sales clerk's tongue out, sending birds to attack girls who mocked him and killing said birds with a baseball bat after one bit him.
- Fanservice: Poison Ivy's story has several panels where she's naked with only some strategically placed leaves obscuring her breasts, her genitalia and some of her buttocks.
- Hero Antagonist: Some stories have Batman appear to make efforts to stop the schemes of the issue's spotlight villain, particularly Poison Ivy and Clayface's one-shots.
- Hollywood Atheist: When Two-Face mocks Holman Hunt's idealism, he remarks that he no longer believes in a benevolent God, implying that his disfigurement and descent into crime are why.
- Horror Host: While the stories of this anthology series had more to do with crime than horror, the Joker serves as a narrator of sorts presenting the stories and making puns and quips about the events and characters involved like the presenter of a horror comic usually would.
- Sadistic Choice: In Two-Face's story, he makes Holman Hunt choose between shooting a restrained Batman or letting his henchman Mr. Castor burn Hunt's wife with acid. Holman instead opts to point his gun at Two-Face, but it turns out Two-Face has a gun of his own, Holman's gun isn't loaded and Batman was really Castor's twin brother Pollux in disguise.
- Valentine's Day Episode: Harley Quinn's story takes place on Valentine's Day and has her break out of Arkham Asylum with the intent of ensuring she has the best romantic evening with the Joker.
- Villain Protagonist: Most of the stories have the Batman adversary given focus serving as the main character.
- You Monster!: In the Penguin's one-shot, Violet calls him a monster after discovering his habit of murdering, maiming or otherwise harming those who slighted him.
