In 1996, riding high on the Grant Morrison relaunch of the Justice League of America, DC Comics attempted to relaunch Teen Titans yet again. It failed miserably, in large part due to massive amounts of Executive Meddling. Most notably, the fact that NO ONE wanted to let the 1996 Teen Titans writer Dan Jurgens use any of the major teen heroes running around DC at the time (particularly Robin III — Tim Drake, who actually WON a fan contest to select a new member of the team — only for the Batman editors to refuse to honor the contest results, resulting in Captain Marvel Jr. being forced upon Jurgens instead.) The lack of "Teen" in the "Titans" didn't help, either.Cancelled in 1998, DC decided to launch a new replacement book; but since the Jurgens Titans series was pretty much universally reviled, it was decided to instead come up with a new name for the new teen book. Meanwhile, Robin's popularity was matched by two other teenage Legacy Characters: Impulse and the Post-Crisis Superboy — and the trio worked as a Power Trio. Hence, "Young Justice" was born.Launched out of a Fifth Week Event tie-in "Girlfrenzy: Young Justice — The Secret" and a Justice League mini-series "World Without Grown-Ups", the series was written by Peter David and ran for 55 issues before being canceled. The cancellation (along with cancellation of another Titans comic that was launched in 1999) of course was done mainly to launch a newTeen Titans comic to complement the recently debuted Teen Titans cartoon series, placing the remaining members of Young Justice under the wing of veterans from the classic Wolfman Titans team.An animated series using the Young Justice title was announced by Cartoon Network during their presentation to the network upfronts on April 21st, 2010. Interestingly, the Teen Titans show was originally pitched as Young Justice.
Young Justice contains examples of:
All Guys Want Cheerleaders: Superboy refuses to go out on patrol with Impulse because he'd rather watch the televised national Cheerleading finals. Sucks to be him as that's where Impulse ends up to stop a robbery and saves the day!
And I Must Scream: The final fate of poor Slo-Bo, frozen as a statue but still alive and aware in the headquarters of Young Justice One-Million.
Joked about with Arrowette. When she feels she is destined to become a villain, she bemoans having to get a black costume that shows off her cleavage. Particularly since she doesn't have much in the way of cleavage to show off. Later on we see an alternate universe evil version of her. Guess what?.
Brick Joke / Chekhov's Gun: For saving his kingdom, Ali Ben Stein offered the boys ANYTHING they wanted. Impulse asked for... well, we never find out, until about 30-odd issues later when the team gets a SPACE SHIP, which just HAPPENS to coincide with a friend of theirs needing a lift into space.
A cross-title one that could be an accident...if it weren't for Grant Morrison's involvement. In the first Young Justice story, a kid gets hold of an all-powerful genie and wreaks havoc. When the team save the world and the League are congratulating them, someone says "So cool!" among the chatter. A year or so later, in a JLA story, a former superhero gets hold of an all-powerful genie and wreaks havoc. The genie here is a revealed to be a 5th-dimensional being like Mxyzptlk, and can be summoned or dismissed by saying his name backwards. His name is Lkz, making his control phrase zkl...pronounced in the comics as "so cool".
Captain Obvious: The series dabbed into this at times when exposition was needed to point out something not clear in comic format. Of course, whenever Young Justice did something the author thought was stupid, it got mocked.
Robin: The kids... They've turned old! And those other kids are dancing out of control!
Superboy: Wow. I can tell you were trained by the world's greatest detective.
The Cuckoolander Was Right: He gets a few of these, particularly during the issue wrapping up Sins of Youth, when he accidentally figures out Robin's real name by reading lips incorrectly. Played for Laughs of course.
Covers Always Lie: The covers generally have little to nothing to do with the story (the Halloween issue, for example, has Robin, Superboy, and Impulse trick-or-treating as their mentors, and the issue where the girls join up has them trying to get into a boarded up Young Justice HQ), but they are usually unrelated enough that one can get the idea that the images are simply sight-gags.
Some issues do fall under this, though; one issue has the team jumping out of the A.P.E.S. headquarters (which is located in Mount Rushmore, up Abraham Lincoln's nose), with Robin shouting "It's gonna blow!" and carrying a detonator, connected to various bombs that are stuffed in Lincoln's nose. Within the comic, however, it's Superboy who defaces Mount Rushmore, and he does it to George Washington, rather than Lincoln. He also does it out of necessity ( well, sort of), and does not use dynamite. Furthermore, the line about blowing Lincoln's nose is said when entering the nose, not exiting, and is just an offhand remark made in reply to Impulse's pun about them running up the nose, instead of the nose running.
Crazy-Prepared: Robin. When the crew went camping, a game of Truth or Dare came up. He was dared to pull his mask off... and so he did, revealing that he had a SECOND mask on underneath! Yup, you can tell he was "trained by the world's greatest detective!"
Evil Twin: Inverted with Slo-Bo, the degenerated clone of Lobo who contained all of the Last Czarnian's "repressed" traits: he was intelligent, good-natured, responsible, monogamous, self-sacrificing...oh, and slowly dying from not receiving any of Lobo's superpowers.
Played more straight with Match, who secretly replaced Superboy for several issues in order to destabilize the team from within and make sure they got bad press.
Fanservice: Surprisingly averted for a 90's comic. Helped by the fact that artist Todd Nanuck drew the characters with the proportions of ACTUAL teenagers (as opposed to other artists working on "teen" books where they drew everyone looking like 20-something underwear models). However, played a bit more straight straight whenever a guest-artist showed up, and later on in the series as Wonder Girl ditched the terrible wig and grew a cup size. Not to mention Empress showing up naked a couple times...
I Lied: Spoiler says this to Secret after suggesting that Robin has talked about her a lot. (Secret, having a crush on Robin, found the idea pleasing.)
Improbable Aiming Skills: Arrowette was assumed to be just another Badass Normal with a bow. Turns out that ever since she was a toddler, she could throw three darts at a time and hit a bullseye, and see things at a distance that her mother needed binoculars to see.
Iwo Jima Pose: The tie-in to the "Our Worlds at War" event featured on its cover a few members of the team (and infamous criminal The Persuader) raising The Persuader's atomic axe in victory.
Leaning on the Fourth Wall: Several times, including the time some characters talk about their comic books being canceled. In-story, they're each talking about their favorite comic books being cancelled (this is the only mention ever of them being comic book fans, and the comic books in question are never named or described, but so what), but to the reader it's clear that they're talking about the characters' solo titles. Two of which were recently cancelled, a third was cancelled years before, and one was still going strong.
Another example: when Arrowette and Wonder Girl were attempting to connect to the Internet using AOL, Cassie started complaining about the unreliability and slowness of the service...only to be quickly hushed by Cissie who hurriedly whispered something in her ear, prompting Cassie to smile falsely at the reader and start talking about how wonderful AOL was. Guess who'd just entered into a corporate partnership with Warner Bros. and parent company Time Warner at the time..? America Online!
Legacy Character: Robin and Cassie "Wonder Girl" Sandsmark are legacy characters for legacy characters.
Power of Friendship: They are all over this trope. They aren't the equals to the JLA or JSA in sheer power. It's their ability to work as a team and the fact that you mess with one, and expect any and all past and present members to show up looking to kick your butt that makes them frightening.
Power Perversion Potential: When Secret manages to partially solidify to catch Superboy from being flung around, he remarks that he didn't know she could do that. Her response? "Oh, I can do all sorts of things you don't know about". Not that Secret normally made such innuendos, but the look on her face sold it as such.
Power Trio: Specifically pointed out by team chaperone Red Tornado in the first issue to convince Robin the three boys ARE a good team together.
"I'll have to get a tight, skimpy black leather outfit that shows off my cleavage. Oh god. I'll have to get cleavage."
Shoot the Rope: Arrowette does this in the Young Justice 80 Page Giant.
Shout-Out: Many, the most blatant when Snapper Carr is all but revealed to be talking on the phone with Rick Jones, who was currently starring in another Peter David written book, Captain Marvel. This is only the tip of the iceberg.
One notable Shout-Out goes to DC's main competitor; more specifically, to their poster boy's origin. A cop chases after a crook, shouting for someone to stop him before he gets to the elevator, and Arrowette lets him pass. The cop then chastizes her, hoping he doesn't shoot someone's mom...or uncle.
In case you're wondering, Arrowette ends up stopping the crook before he gets too far.
Possibly unintentional, but Spectre at one point says to Secret, "Dead girls don't eat ice cream". It's farfetched, but this the same phrasing of every title of The Bailey School Kids books, with a similar subject (a monster or supernatural creature) and action that they don't do (something trivial and normal for humans).
