In 1986,DC Comics made comic book history by rebooting their entire continuity inCrisis on Infinite Earths. Character histories were changed, merged in from other continuities, or even restarted from scratch. ThePost-CrisisDC Universe would never be the same.
In 2011, they did it again.
The "New 52" is DC's second major reboot, following theFlashpoint event. (There were two otherCosmic Retcons- withZero Hour andInfinite Crisis /52 - but they were largely cosmetic.) In the wake ofThe Flash messing with theTimey-Wimey Ball, DC canceled all their ongoings and launched 52 new titles in their place. In this new continuity, superheroes have only emerged publicly in the last five years or so, with many only beginning to show up now. Even so, many major prior storylines are still canon, at least inBroad Strokes.Vertigo Comics andWildstorm characters have also been incorporated into this new continuity.
Of course, DC wouldn't let things stop there. In January 2012 they overhauled their corporate logo, and a "Second Wave" launched in May, with six underperforming titles ended and replaced with six new ones. They followed that up with "Zero Month" for the reboot's one-year anniversary with #0Origins Issues and some more new launches.
All three Super-characters have been scaled back to earlier versions and are having their alien-ness highlighted: Clark Kent is not married toLois Lane and both Ma and Pa Kent have passed away, Superboy is a lab experiment intended to be used as a weapon, and Supergirl has only recently arrived from Krypton.Action Comics is now a Superman version ofBatman: Year One. The other main change is that, like in theBronze Age, the Daily Planet has been bought by Galaxy Broadcasting. This time, however, it's Lois who's moved to TV and Clark who's staying with print journalism.
The Bat-books pick up where they left off, withBruce Wayne appointing Batmen worldwide (including Batwing, who operates in Africa). However Dick Grayson, who had been one of these Batmen, gave up the mantle and returned to being Nightwing. Barbara Gordon has also recovered from her paralysis and become Batgirl again, booting Stephanie Brown from the role. The books also introduced the Court of Owls, anAncient Conspiracy that has run Gotham for generations and has ties to Grayson's past.
Like Batman, Green Lantern was especially successful prior to the reboot, so it keeps its recent history with corps of multiple colors emerging. Hal Jordan has been dismissed from the Corps due to the "War of the Green Lanterns" and replaced bySinestro of all people, though he soon takes Hal on as a sidekick. Kyle Rayner, meanwhile, has defied the Guardians and joined an alliance of Lanterns of other colors; and Atrocitus has begun reorganizing his Red Lanterns with a new sense of purpose.
The Fury ofFirestorm - Firestorm was rebooted and the very nature of his powers changed; rather than requiring aFusion Dance, each person can become a Firestorm and can then merge into a stronger being if they wish. It's also being reimagined as an arms race metaphor, with multiple countries developing their own Firestorms.
The SavageHawkman - The details of the rebooted Hawkman are unclear, but needless to say the infamousHawk-Snarl is wiped away. Hawkgirl is nowhere to be seen, but she was MIA before the reboot as well; we don't know what's going on there.
Mister Terrific
DC Universe Presents (anthology series; the first arc featuredDeadman, the second is the Challengers of the Unknown, and the third isVandal Savage.)
Huntress/Power Girl: Worlds' Finest - Both characters have been returned to to their original Earth-2 origins, though they're now stranded on Earth-Prime.
The Question: Previously an investigator in a mask, he is now punished for unknown crimes by having his face and name removed.
Pandora: A new character and the one who prompted the reboot by making the Flash aware of multiple timelines to merge together. She's the actual mythological Pandora, punished for opening the box and releasing evils unto the world. Feeling her sentence was unjust, being branded as evil when she didn't intend any harm, she's now working to end her curse - even if the Justice League pays the price.
Tropes used inNew 52 include:
Adaptational Villainy: Inverted! Silver Banshee, who admittedly has only just been reintroduced inSupergirl gets avery likable introduction suggesting her depiction might be written as either aTragic Villain, anAnti-Villain or even outright heroic character.
Played straight with Mr. Freeze, who has been revised to be less of anAnti-Villain. He's still out to cure his frozen wife Nora - but this is a lie. Nora was preserved long before Freeze was even born, he's just deluded himself into believing they're married as part of his obsession with cold.
Alternate Universe: The second wave is re-establishing Earth-2. (Not only with theEarth 2 comic itself, but the stars ofWorlds' Finest are refugees from that reality.)
Grant Morrison has introduced Earth-23, a universe where all super heroes are black and Superman is President (and drawn to resemble Obama) first seen inFinal Crisis, a universe where a robotic Superman conquered Earth, and a universe of super deformed super heroes(first seen in Superman/Batman #51).
Not to mention Earth 1, Earth 12, and Earth 16 being the Earth One graphic novels, The DCAU, andYoung Justice cartoon respectively.
In his new series, most people react toAquaman as if they only knew him from theSuperfriends,What Kind Of Lame Power Is Talking To Fish, Anyway? version. This leads to him working so hard to prove that he isBadass that it doesn't actually make any sense for him to have that reputation he's trying so hard to shed in the first place.
Darker and Edgier: Some aspects are this compared to when we last saw them; including Earth-2 and Blue Beetle.
The entire Teen Titans, as clearly shown on their first cover. Most of their team has a red and black color scheme.
Billy Batson has become jerkish from losing his parents. While he has still shown a hidden heart of gold, it's still jarring for readers used to seeing him as the ultimateNice Guy.
Easter Egg: Each Issue #1 (in the first wave at least) included a one-panel background appearance by Pandora.
Flashback Arc: BothAction Comics andJustice League begin with arcs showing how Superman and the League, respectively, got their start.Earth-2 andWorlds' Finest begin with flashbacks showing howthat universe's Superman, Batman and Wonder Woman died and how Huntress and Power Girl arrived on Earth-Prime.
Hotter and Sexier: Catwoman and especially Starfire (inRed Hood) initially took some heat for being oversexualized at the cost of characterization. Power Girl, on the other hand, was criticized for her costume removing being notably less sexy.
In Name Only:DC Comics Presents: Challengers Of The Unknown stars nine characters who have the same names and roughly the same appearances as the five original Challengers and the four 90s Challengers. And they survive a plane crash. That is the sum total of similarities between the characters.
Legacy Implosion: The titles of bothBatman andBatgirl have reverted to their original owners.The Flash continues the focus on the original, Barry Allen, that had started a few years prior, but the reboot wipes out most of the rest of the Flash-family. The Justice Society has suffered a major legacy implosion, with the all of the children and grandchildren wiped from existence and the original JSA members becoming young again.
Mythology Gag: Batwing's costume looks a lot like the imaginary African-American Batman (aka "Bat-Wings") in the seventies comic "The Batman Nobody Knows". Only less seventies.
Never Trust a Trailer:Most of the hype forEarth-2 focused on that world's versions of the Big Three: Superman, Batman, and Wonder Woman. They're killed off in the first issue.
Nineties Anti-Hero: There have been some comparisons of the New 52 with the early days ofImage Comics, which may be something to be expected when you've got Image co-foundersJim Lee andRob Liefeld working for you.
As of the 7th issue of Justice League, Etta Candy.
More of an 'Ethnicity Lift' but Siver Banshee is now explicitly Irish rather than being from a fictional half-Irish, half-Scottish island (though her accent is still a little... out there.) Oddly her surname was changed to the rather un-Irish 'Smythe'.
Rob Liefeld: He's worked on "Hawk and Dove," "Hawkman," "Grifter," and "Deathstroke."
Suddenly Sexuality: Alan Scott is now homosexual, despite being married several times in the old DC universe and being a man with an eye for the ladies when he was younger.Word of God states that the writer wanted to make Alan gay to make up for his gay son, Obsidian, being retconned out of existence.
Throwing Off the Disability: Barbara Gordon, who had her paralysis healed. It should be noted that the writers are aware of the trope'sUnfortunate Implications and are having Barbara continue to struggle with the psychological scars.
Wolverine Publicity: Batman and the other Gotham heroes appear in more books than any other, even the Lantern series.
Younger and Hipper: Just about all the heroes, but especially the Earth-2 characters; who are now the same ages as their more mainstream counterparts when they were traditionallyOlder and Wiser.
