After the events of Schism and Avengers vs. X-Men, the X-Men have broken apart down ideological lines. At the former mansion, Wolverine, poorly suited to the task, headmasters at the Jean Grey School with several other mutants who followed him from Utopia. His goal: teach them to survive in a world that hates and fears them.The Phoenix Five, plus Magneto, led by Scott Summers, are on the run. After using their Phoenix powers to change the world as they saw fit, they're now considered terrorists. Cyclops has them teleporting around the world to rescue or approach new mutants as they manifest. Cyclops' goal: time for a revolution, and he needs an army.Dr. Hank McCoy, dying as a result of further mutations, hears an offhand remark from Iceman, along the order of: "If only Scott could see himself..." and decides that's a brilliant idea. He goes to the past and brings the original five X-Men to the present day in hopes of young, idealistic Cyclops finding a way to get through to current Cyclops. The young X-Men, stunned by the revelation, take a vote and decide to stay to help things become closer to the dream Professor X brought them together to realize. Events progress and it becomes clear that not everything was as they were told upon arriving, in addition to several changes in the team dynamics and emotional impacts, which result in the O5 X-Men and Kitty Pryde deciding to join the New Xavier School in hopes of being able to continue their attempt to bring mutantkind and mankind together.Due to the nature of the series many events cross over and/or happen concurrently with events in Wolverine and the X-Men and with Uncanny X-Men respectively. This book is pretty much essential reading for the Battle Of The AtomBat Family Crossover and the page may contain unmarked spoilers about its conclusion. The Cyclops (2014) series spun-out of this series, and its page also contains spoilers regarding this book.
All-New X-Men provides examples of the following tropes:
Adorkable: A teenaged Cyclops with none of the jerkassery associated with his older self. If he didn't already qualify for this, his hugs certainly make him do.
Battle Trophy: In a fight with the new Silver Samurai, Beast survives only because Jean and Scott double-team the Samurai. Beast then takes a dropped katana, outright saying that he is so going to keep it.
Beauty Mark: When drawn by Sara Pichelli, Laura has one under her right eye.
Big Bad Duumvirate: Raze and Young Xavier are revealed as the heads of the Future Brotherhood. Before, it seemed like Raze was The Dragon, but it's actually both of them who thought of their plan.
Big Damn Heroes: Laura in #29, arriving on the scene while Xavier, Jr. is on the verge of victory, and takes him by surprise while Jean helps cloak her from his mind. The attack breaks Xavier's control over everyone, including the future Brotherhood whom he had been controlling from the start, and turns the tide of the battle.
Comic Book Time: Is beginning to become an issue, since it isn't clear what year the original X-Men came from. The stories were originally set in the '60s, but going by the ages of certain characters, it seems they actually came from the '80s instead. Throw Marvel's "sliding timeline" into the mix, and it's anyone's guess when they're from. Jean did joke that her clothes made her feel like she was "from 1963".
Issue 18 has Kitty holding one of the O5 X-Men's suits in a mournful pose, with the rest on the ground around her and feathers falling from above... the issue is actually pretty lighthearted.
Issue 20 has X-23 kissing Teen!Scott on the cover. The closest thing we get is a hug in the actual volume.
Likewise, Issue 30's cover prominently shows Laura and Warren sharing a passionate in-flight kiss. In the issue itself there's certainly a fair amount of Ship Tease, but it's never made clear whether or not Laura and Warren actually did more than that (see Did They or Didn't They? below).
Curb-Stomp Battle: The only way to describe over a hundred HYDRA getting beaten by Teen Angel and Modern Angel.
Death Is Cheap: Apparently. Christopher can not only bring back the dead, but he seems to heal himself from a throat stab that left him without a pulse.
Did They or Didn't They?: In #30, Laura wakes up at one of the Worthington family's estates the morning after a date with Warren, who returns shirtless from a morning flight. Laura is in a similar state of undress, their clothes are scattered across the room, and some of the furniture is upended. Laura remembers very little of the night before, with Warren left to fill her in. However all the reader is shown is the pair getting into a fight with some punks while dancing at a club, and Warren telling her that was only the beginning as he flies away with her. Whether or not they slept together is never even discussed, as the conversation is focused mainly on Laura asking Warren why he likes her, and touching on how badly she needed a night away from the insanity of being an X-Man. The end of the issue leaves it ambiguous whether they did indeed have sex.
Disappeared Dad: Cyclops saw his dad die some time ago in the past, only to find him now in the present. Young Cyclops is overwhelmed, while his dad Corsair handles the meeting pretty well (because it's the second time he's met/reconciled with his boy, from his point of view.
Emergency Transformation: Teen Hank works with Modern Hank to save himself from the mutation that's killing him. In the process, he undergoes another transformation. He's still blue and furry, but no longer cat-like, nor does he look exactly like his old blue-furred self.
Executive Meddling: Bendis accuses editorial of this during Battle of the Atom, forcing him to rewrite or alter the plot from what he intended (see Retcon below).
Face-Heel Turn: Molly Hayes is revealed to become a member of the Brotherhood of Mutants in the future during Battle of the Atom, and returns again in an arc beginning in #26. Eventually subverted, since it's revealed that Young xavier essentially mind raped all of the Brotherhood other than Raze.
Five-Man Band: Played with. The O5 X-Men started out as a literal five person team, but the dynamics shifted around once they got to the modern day. They dropped in actual physical numbers once Warren left to join Modern Cyclops' team, but when the entire group defects to his side they're together once again.
Freak Out!: Teen Angel after meeting his modern counterpart, at the end of Issue 8.
Teen Jean Grey is horrified of all that she knows she will go through, but especially the Phoenix-related bits.
Teen Angel is a little wigged out by — if not precisely scared of — his future counterpart.
Subverted with Teen Bobby and Modern Bobby until in Battle of the Atom, they meet versions of themselves from further in the future Ice Wizard and Ice Hulk, and both are a little wigged out. But Teen and Modern Bobby still get along fairly well, and agree on their mutual wigged-out-ness.
Subverted with the Hanks, who are both brilliant and know the importance of working together. Both later gain some issues with Future!Beast from the crossover event.
Future Badass: Uatu shows Beast visions of the possible futures the X-Men could have had, one of which has Magik becoming Doctor Strange's successor as the Sorcerer Supreme of Earth, making her the Sorcerer Supreme twice over.
Good Thing You Can Heal: Triage, who recovers from being stabbed in the neck, which was actually unexpected, given that nobody was aware he could heal himself.
Jean has one when she sees what happens to her future self. Scott has one for a couple issues, after Jean rejects him, Warren has a big one at the end of issue #8. Bobby and Hank have stayed shockingly even-keeled in comparison. Jean has an even worse one after Angel leaves to join Modern Cyclops.
Future!Beast had one when President Blaire died, and we're led to believe it's what brought on his Start of Darkness. However, it's later revealed that he just snapped due to it, and Xavier is controlling him.
X-23 is in the midst of one when the O5 rescue her from Purifiers, both due to the severity of the torture they inflicted on her (torturing her nearly to death repeatedly, only to let her heal enough for another round) and the aftermath of Murderworld. When the team finds her she's wandering Miami in an amnesiac state, though her memory does return shortly after. Being confronted with Arcade's footage of herself attacking her friends in a trigger scent-fueled rage nearly sends her over the edge again, but she manages to hold it together with Scott's support.
Heel-Face Turn: Future Molly, Beast, and Deadpool promptly turn on Xavier Jr. when his influence over them is broken, revealing they had been mind controlled by him from the start and were not willing participants in his actions. Future Jean is revealed to no longer exist.
High Concept: Bendis mentioned early in interviews what the idea of this book was. Literally, "Man what would the kids think about how far this franchise has come?".
Jerkass Has a Point: The Purifiers are monsters, make no mistake, but Stryker Jr does have a point that the O5 shouldn't have been pulled out of their time period in the first place because Beast did whatever he felt like doing. Given that this was the tipping point that ripped space-time and dumped 616-Galactus into the Ultimate Universe, he's right.
Kangaroo Court: When various alien organizations learn Jean Grey is alive again, they seek to prosecute her for her future self's actions as Dark Phoenix.
Kick the Dog: Jeen, see Took a Level in Jerkass, but Logan really kicked a whole pack of puppies when he tried to rally a lynch mob to execute the completely innocent Teenclops.
Kid from the Future: During the Battle of the Atom crossover, several were introduced, but the ones whose parentage were actually explained within this series were:
Raze, who is the son of Mystique and Wolverine, and possesses both their power sets.
Charles, eventually Future!Xavier, is the child of Mystique and Xavier, but only possesses Xavier's power set, though also has telekinisis.
Knight in Sour Armor: Teen Cyclops has taken on this trait, trying to do as much good as possible despite everyone eying him with suspicion and Jean treating him as if he's done the things his future counterpart did.
Teen Scott and Jean were in love until they got to the future. Now she's not so sure she wants him anymore given what she knows about who/what he grows up to be, while he's still smitten, thinking that their eventual wedding is "proof" they're supposed to be together.
Wolverine is still in love with Jean, even though knowing that this one is way too young.
O5 Hank and Jean kiss. She instigated it on top of that. The events of Battle of the Atom cause a little fallout, and they're still not sure what's going on between them.
Jean and Teen Angel have a moment when he catches her when she's falling.
When the helicarrier launched its missile barrage at them, Teen Angel thought it was it for him and started declaring that he had always been in love with Jean. Fortunately for him, he never had to finish when the rest of the X-Men took down the missiles.
Teen Scott is also mentally thinking over making a move on the Stepford Cuckoos and then X-23.
Jean seems to be attracted to regular Scott, but he quickly says it can't ever happen. Ever.
X-23 and Angel go on a date in #30, which ends the following morning at one of Warren's family retreats. Though never explicitly addressed, it's implied they did have sex the night before.
Manipulative Bastard: Mystique, starting in issue 7 to Teen Cyclops and setting up a conflict between the O5 and Avengers.
A Mind Is a Terrible Thing to Read: Jeen reads the Purifiers' minds to learn just how messed up they are towards mutants and their hate crimes. She's also left quite disturbed when she reads part of Laura's mind, and learns about the things that were done to her (Kitty did warn her not to read Laura, though).
Mind Over Manners: Jean's telepathy shows up unexpectedly due to the stress of seeing the future and knowing her future self dies (more than once). Kitty has to repeatedly remind her it's considered extremely impolite to read minds without permission. Jean apologizes, but her curiosity gets the better of her quite a bit. Sometimes Hilarity Ensues, sometimes it leads to Awkward Moments, but most times she can't believe what people have done.
The Stepford Sisters do this to Jean after she tried to do it to Warren again in Issue 11.
Essentially how Future Xavier formed the Future Brotherhood.
Mind Screw: During the second battle against the Future Brotherhood in issues 26-29, Xorna is revealed at the end to no longer exist when after the defeat of Xavier Jr. her armor is removed to reveal nothing inside. Jean's realization of the dangers of uncontrolled telepathy may have caused that future version of herself to vanish Back to the Future-style, but as Future Jean's face was never shown this time, it's left unclear whether Xorna in Battle of the Atom was actually real, or a projection of Xavier Jr.'s as well.
Missing Mom: Scott, emboldened by finding his father alive after believing him dead, asks after his mother. But she is really dead.
Motor Mouth: Teen Bobby tends to chatter, especially when nervous, but also just to hear himself talk it seems.
Mythology Gag: Issue 10 has an illusion of zombified heroes, as a reference to the Marvel Zombies series.
Nice Job Breaking It, Hero: Uatu the Watcher specifically says that Beast's actions have destroyed any chance of mutants being accepted and any happy endings any X-Man could have had.
Overshadowed by Awesome: X-23 suffers from this in the "Trial of Jean Grey" arc, as her skills overlap with Gamora's and Angela's; one of whom is a virtually god-like being from another universe. So she ends up with nothing to do because any help she could offer (particularly seizing the ship they use to infiltrate the Shi'ar homeworld, which falls right in line with her assassin/black ops training. Whereas Angela just makes a bloody mess doing so) gets taken care of by one of the Guardians instead. It even gets a lampshade by Quill about having not even realized she was with them.
People Puppets: Teen!Xavier has had his Brotherhood members under his control the whole time, with the exception of his brother.
Power Glows: Jeen's new powers make her glow completely in psionic energy.
Power Incontinence: All over the place with the new-born Mutants. All the Phoenix-touched members of Cyclops' team except Magik at least until later in Uncanny X-Men seem to have intermittent control problems. And Jean's telepathy manifests early as a result of the stress of time travel and finding out about the future, and she frequently has to fight to keep thoughts out of her head. Eventually it causes her to gain a whole new power by combining her two powers.
Retcon: Bendis has now established that the Future Brotherhood from Battle Of The Atom wasn't evil....except for Raze and Kid-Xavier, who mindcontrolled the rest. Bendis is even on record saying that much of what happened in Battle Of The Atom was against his original plans due to editorial mandate, and he was taking the opportunity in issues 26-29 to bring it more in line with his intent now that he had more creative control.
Ship Tease: Teen Scott thinks about hitting on X-23, though the cover of Issue 30◊ and the solicit for Issue 31 state she's taking "an odd interest" in Teen Angel instead. Previews for Issue 30 cement it with Laura and Warren waking up in bed together after a heavily implied night of sex.
Swapped Roles: Kitty Pryde, who was 13 and a half when she joined the X-Men, studied under Jean and learned techniques for handling telepathic issues. Now she's an adult, teaching 16-year-old Jean from the past those same techniques.
Jeen, due to her Trauma Conga Line. She brainwashes Warren into submission twice! And now in Battle of the Atom she manipulates Teen Scott by flattering him (after kissing Hank) to help her stay in the present, which will cause an Apocalyptic Future.
Kitty Pryde after Teen!Scott leaves. She acts like a jerk to Scott and says she doesn't want Scott and Jeen alone, since Jeen showed some attraction to Scott... even though she admits that Scott handled the situation well. Then, she berates Angel for letting X-23 leave, even though there's nothing he could've done outside knocking her out, which he probably couldn't even have done.
Trauma Conga Line: Jean, a 16 year old girl, has her powers blooming early, with her attempts to deal with Power Incontinence adding to her troubles. She finds out she is going to die (repeatedly) and is, as far as she knows, still dead, while her teammates survive to the current day.
Also, Scott got one as well. He learns that his future self is the next Magneto, his first true love Jean dies numerous times over and the mutant race almost goes extinct. However, he is certainly managing it better than Jean.
In issue 8, Jean modifies Teen Angel's behavior after he, understandably, panics and tries to go back home. When Hank tries to call her out on this, she responds with "Henry, don't you of all people start lecturing me on using your God-given things for selfish purposes."
Several other characters past and present pull this on Modern!Hank for bringing the original 5 forward without much of a plan for what to do with them if they failed to stop Modern!Cyclops in their first encounter. To be fair he was suffering from a mortal illness at the time, but the possibility that he has done more harm than good has come up with some frequency. Modern Hank gets another one because he didn't give the whole story about the Phoenix possessing Modern Scott at the time when he recruited their younger counterparts.
Then Jean gets it again after her meltdown when Angel leaves.
And the entire O5 team gives one to the Avengers once they find out about the Scarlet Witch and "no more mutants". The Avengers are left stammering on the defensive.
You Keep Using That Word: A big part of the conflict between Wolverine's side and Cyclops and his side during the start of this book was Cyclops repeatedly calling for "revolution". Everyone in the book, and some readers, acted like he was trying to take over the US and establish a new government, as that's what that word tends to imply, rather than that he was protecting newly emerging mutants at all costs or returning to previous practices they did during the times where the X-Men were more stable, which was what he was actually doing. Thankfully they stopped using this word once Bendis' volume of Uncanny X-Men started up, where it became clear that he was merely trying to protect the new mutants and wasn't trying to harm humans at all (in fact he ends up near suicidal when his actions lead to accidentally endangering some human protesters who were arguing against anti-mutant sentiment in a later issue of the other book).
You Make Me Sick: Uatu the Watcher of all people, says this to Beast, since his actions in taking the O5 to the present have effectively screwed over every mutant ever in several universes that would have otherwise achieved mutant equality. This is even worse for Hank, since Uatu said this right before the Original Sin crossover, wherein he died.
Uatu: I am the Watcher. I do not act. And you disgust me, Hank McCoy.
