DC Nation is a programming block currently airing on Cartoon Network. As the name implies, the block consists exclusively of material based on properties owned by DC Comics.The block first consisted of:
Animal Wrongs Group: When Animal Man defeats a villain, it's not for whatever crime they were committing at the time, but because they were accidentally endangering some random animal. Once he ignored an invasion by Darkseid to chew out a guy for leaving his dog tied up on the sidewalk.
Animesque: Many of the shorts, particularly Amethyst, New Teen Titans and Baby Superman (The first and last ones were actually animated in Japan by David Production).
Car Fu: In the third Wonder Woman short, Diana rams her Charger into Giganta's head.
In the second Princess of Gemworld short, Amethyst fights a goo monster and gets covered in slime. She turns her outfit into a makeshift swimsuit and takes a swim in a lake. The enchanted forest makes itself known and makes it sound like they were watching her skinny dip. She covers her (clothed) chest a few times in their presence.
Gilligan Cut: From Tales of Metropolis: Featuring Jimmy Olsen
Jimmy: It would be easier if I never saw Superman again!
(cut to title card reading "Literally four seconds Later")
Jimmy,(being attacked by a giant octopus): Save me, Superman!
Black Lightning's old costume seen in the first short is Black Vulcan's costume from Super Friends.
In the Black Lightning short "Clothes Make The Hero", Thunder is seen texting someone. A brief shot of her cell phone display reveals that it's "Grace", referring to Grace Choi, who is her girlfriend in the comics.
The New Teen Titans short "Turn Back The Clock" briefly has the team wear their embarrassing 90's costumes.

At the end of that episode when Robin knocks the time machine into fast forward, we meet the Titans lineup from Adam Warren's one-shot Prestige issue "Scissors Paper Stone."
Paper-Thin Disguise: In Tales of Metropolis: featuring Bizarro, Bizarro tries to enter the Daily Planet disguised as mild mannered reporter, Not-Bizarro. Lois Lane is not fooled, but Jimmy Olsen is.
Race Lift: The Bat Man of Shanghai shorts have Batman, Catwoman, and Bane reimagined as Chinese martial artists in the 1930's.
Reality Breaking Paradox: One Teen Titans short had Cyborg and Robin get into an escalating war of This Is My Side, which ends when they start a fight over the tape they were dividing things with, which blows up the whole planet.
Cyborg: You can't divide tape with tape! You created a paradox!
The Determinator: Lois Lane in the "Tales of Metropolis" short featuring her and Batman. The fact that she clings onto the Bat Plane, gets dunked off and swims to Gotham...
This Is My Side: The Teen Titans short "Taped Before A Live Studio Audience" had Robin and Cyborg get into a major escalating war of this after the two want to do something different on TV, taping everything in half - the tower, a donut, the Titans themselves, The Brain... before they get to another roll of tape and...
