---

This work provides examples of:

• A.I. Is a Crapshoot: Well, it is when Joker is the one giving it personality.
• Attention Whore: Clayface
• Bad "Bad Acting": Clayface has his moments. He eventually just gives up trying during a confrontation with the heroes when trying to impersonate Batman.
• Big Bad: The Joker. He assembles a team of villains to assist him in shutting down all the power in Gotham and rebranding the town as Jokertown.
• Big Eater: Grundy
  Grundy: Grundy's got fast metabolism!
• Bloodless Carnage: Grundy manages to beat up the security guards without a single death.
• Break Out the Museum Piece: With Joker's virus disabling everything connected to the Internet, the heroes literally go to a history museum to fight Joker's Mecha with a WWII era fighter plane, motorcycles and a tank.
• Brick Joke: "Quick selfie?"
• The Brute: Grundy and Clayface.
• Chewing the Scenery: Scarecrow nearly says the trope name outright when arguing with Clayface.
• Continuity Nod: Batman still has Ace, the robotic wolf with the motorcycle form that he acquired from Penguin in Batman Unlimited: Animal Instincts. Red Robin's glider is a robotic bat from the film as well.
• The Dragon: Scarecrow seems to fit this position best.
• Electrified Bathtub: Batman lures Grundy into a tunnel of love ride and electrifies the water with a power cable.
• Everything Is Online: Joker's virus shuts down everything electronic, including televisions, cars, and even police weapons (biometric scanners). Curiously, Nightwing manages to procure an outdated but still functioning cell phone.
• Feed It a Bomb: Robin takes out Clayface by throwing one of his smoke grenades into his mouth, leading to an inflated head and a puff of smoke from his mouth. The next time they meet, he just throws explosives into Clayface's body; but this time, the bombs contain quick drying cement.
• For Halloween, I Am Going as Myself: "Grundy loves Halloween!"
• Halloween Episode: Takes place on Halloween.
• Knockout Gas: On their second encounter, Green Arrow uses a knockout gas arrow to sedate Silver Banshee.
• Lighter and Softer: As with the first movie, it provides a counterbalance to the grittier and more adult material of DC Universe Animated Original Movies.^note And to the Batman: Arkham Series, considering three voice actors reprise roles from that series in this movie.
• My Friends... and Zoidberg: Joker forgets the Silver Banshee's name.
• Mythology Gag:
  • Scarecrow causes Nightwing to see visions of himself as Robin and in his first Nightwing costume.
  • Joker leads a group of villains in a plan to take over the world.
  • Even though the Joker calls himself "King of Gotham", he resembles Emperor Joker.
  • The futuristic buildings resemble the setting of Batman Beyond. Word of God says it was intentional.
  • Gladys Windsmere^note Clayface in disguise mistaken Cyborg for Robotman.
  • Gogo being blindfolded, similarly done in the 1966 series.
  • The crowd at the parade wearing Joker masks (albeit forcibly).
  • Batman facing a digital Joker virus is similar to Batman: Digital Justice, only with the original Batman.
• Never Trust a Trailer: The trailer made it seem like it was Joker kidnapping Cyborg was what caused the problems in the movie. While the virus does take control of Cyborg, it was actually them kidnapping Gogo that led to the virus's existence.
• "Not So Different" Remark: "Oh Bats, sometimes I think you're as crazy as I am."
• Pet the Dog: The Joker gives Grundy an ice cream...and actually an ice cream cone, not an explosive or anything. Sadly Grundy loses it after he is attacked by Nightwing.
• Paper-Thin Disguise: Solomon Grundy breaks into a lab dressed as a pizza delivery boy, complete with scooter. He gets a little upset no one fell for it.
• Shut Up, Hannibal!: Nightwing overcomes Scarecrow's combination of fear gas and a breaking lecture.
• Sky Surfing: Red Robin has one in the form of a bird.
• Spot the Imposter: Red Robin figures out which is Gogo Shoto and Clayface by asking them something from Gogo's video game.
• Static Stun Gun: At the parade, Nightwing uses his electrified batons to defeat Scarecrow.
• Stealth Hi/Bye: Green Arrow manages this on Nightwing, although the later was probably expecting Batman to show up and didn't bother checking who was behind him.
• Take Over the World: The Joker states this is his plan.
• Take the Wheel: During their joy ride, Silver Banshee tells Solomon Grundy to take the wheel so she can take out the cops that are following them. After ditching the cops, Grundy throws his arms in the air to celebrate, requiring Banshee to grab the wheel.
• Tap on the Head: Green Arrow beans Silver Banshee in the back of the head with a softball, and Nightwing takes out Scarecrow with a "knockout punch".
• This Is Gonna Suck:
  • Joker's mech vs. Green Arrow in a tank.
  • Joker's Powered Armor vs. Cyborg's fist.
    Joker (both times): Uh oh.
• Those Two Guys: Solomon Grundy and Silver Banshee are almost always seen together.
• Trap Door: Commissioner Gordon uses one to trap Solomon Grundy in the parade float.
• Took a Level in Badass: Clayface can fly in this film. Not bad for a guy made out of mud.
• You Don't Look Like You: Both played straight and averted with the Joker. Played straight in the sense that he doesn't resemble the figures from the toyline these movies are based on, which feature the Joker in militaristic gear with jagged teeth. Averted in the sense that his depiction is far more in line with traditional versions of the character.
