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:
Teen Titans Go! (reruns, new episodes premiere Tuesday night in prime time)
As of fall 2013, Beware the Batman has been replaced by a second rerun of Teen Titans Go! .In addition to the television programs, the block also shows numerous animated shorts, often showcasing lesser known properties. Among them are:
Tales of Metropolis: Shorts depicting a day in the life of one of Superman's friends or foes.
Green Arrow: Shorts depicting Green Arrow and Black Canary fighting crime, with the duo wearing TRON inspired costumes and GA carrying around a bow with a talking A.I..
Compare with Marvel Universe, a similar block on Disney XD that features content based off Marvel Comics properties.As of 2014, the block seems to have been discontinued with the shorts airing around the Teen Titan GO! episodes on Saturdays. Further cementing this is the fact Beware the Batman is being put on the Toonami block.
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.
The Cat Came Back: In Tales of Metropolis, Lois Lane manages to pull this on Batman, of all people.
Cool Car: Diana drives one in the Wonder Woman shorts. And yes, it turns invisible.
Clothes Make the Superman: Very literally in "Baby Superman", in which Superman gives his cape to a baby to use as a diaper, transforming the baby into Superman himself.
The Determinator: Lois Lane in the "Tales of Metropolis" short featuring her and Batman. In a few of the stunts she pulls to try and interview him, she clings onto the Bat Plane, gets dunked off and swims to Gotham...
Funny Background Event: During the part of the third Tales of Metropolis short in which Jimmy rants about times he regrets becoming Superman's pal, Bizarro (in his "secret" identity of Not-Bizarro) pulls a brown lunch bag out of the fridge, eats it up, and leaves by flying through the ceiling.
Furry Confusion : In the Farm League shorts, Aquamandrill apparently has his human counterpart's powers over sea life... So he tries to force the Flish (The Flash, but as a fish) to do his chores for him. It doesn't work, but it greatly annoys the Flish.
Also, Wonderwombat has no idea what she's supposed to eat as a wombat, which doesn't stop her from loudly claiming that she wants to eat "whatever it is that wombats eat !".
In the third 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. Beast Boy makes sure to diss Robin's mullet before being horrified to see he has one as well. The same skit also has them wearing their 80's costumes. Upon seeing her revealing outfit, Starfire becomes mortified and tries to cover herself, which is much easier with the incredibly long hair she had at the time.
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" and the robot Robin from DC One Million.
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.
Paranoia Fuel: In-Universe and Parodied in the Plastic Man short "Untouchable", a mob realizes that Plastic Man could be anywhere, and then end up going stir-crazy when the room they're in has his color scheme everywhere, with everyone wearing the color scheme to some extent as well. Turns out they went crazy for nothing, as Plastic Man slept too long and completely forgot he was supposed to go to the stakeout with said mob.
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!
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...
