Ultimate X-Men is a reboot of the X-Men franchise in the Ultimate Marvel line of comics, it can be seen as one of the most radical reimaginings, with Alternate Character Interpretations of the mainstream 616 characters being taken as canon while other characters are given completely different backstories and characterizations. It was far less popular than its sister series Ultimate Spider-Man, due to a constant rotation of artists and writers, churning out ultra-violent storylines that went from good, to bad, to just plain weird. It was eventually canceled after a few bad story lines that culminated in the universally reviled Ultimatum event.The series lasted for 100 issues, from February, 2001 to April, 2009. After Ultimatum, the series was replaced with Ultimate X, where mutants that survived the tragedy were scattered, hunted, and leaderless. This new series only lasted 5 issues, from April, 2010 to August, 2011. However, the series was relaunched as Ultimate Comics: X-Men with the mutants starting to band together again after the events of Ultimate Origins revealed the secret origin of the mutant species. The new series written by Nick Spencer (Morning Glories), dealing with the fallout of this origin being revealed to the public along with the events of the Ultimate Hawkeye series. As of issue 13, Brian Wood (DMZ) takes over writing duties on the title.
Ultimate X-Men provides examples of the following tropes:
After a few issues, Bishop states that in the future he and Psylocke will be married. He's killed an issue and a half later and these claims are never elaborated upon.
The Ace: Magician is more ripped than Bobby, formulates a plan to take out the Brotherhood and has enough people skills that in front of the cameras he fixes the X-Men's reputation. Within 24 hours after joining the X-Men. However, it turns out that his power is that he's a semi-conscious Reality Warper, so reality restructured itself around his desire to be The Ace.
Beard of Evil: Inverted with Magneto, who grows a beard shortly after Professor Xavier uses telepathic blocks to turn him into a normal law-abiding citizen. As soon as the blocks are removed and he reverts to his old villainous ways, he loses the beard.
Coattail-Riding Relative: Initially, the Beast's parents disown him for being a mutant. Later, when the X-Men have achieved fame and (temporary) renown, they return and claim they always loved him... after they've made millions writing a book about how they lovingly raised such a wonderful young mutant.
Banshee is Professor Moira MacTaggert using the Banshee serum.
Ultimate Proteus (David Xavier) is a composite of 616-Proteus (Kevin MacTaggert) and Legion (David Haller). Though his powers are based on 616-Proteus, his personality is more in line with Legion, and his parentage is based on a combination of the two.
William Stryker becomes two characters. William Sr. is an anti-mutant military leader, as in the second X-Men film, while William Jr. is the religious extremist from the original comics. William Jr. is also a Composite Character as later becomes Ultimate Universe Master Mold; gigantic Sentinel.
Also done with Angel, with his "Archangel" identity going to Derek Morgan.
Professor Xavier. It's a much more obvious, and in many ways bigger, issue with Xavier, having had at least two relationships in the past with students; Mystique and Emma Frost, and just before the end of the series admitted to being in love with Jean Grey.
Dissonant Serenity: Moira MacTaggert, examining Wolverine after he's been run over by a truck, just calmly remarks that it looks like an autopsy in reverse.
Does Not Like Shoes: Both Beast, Nightcrawler and Jimmy Hudson. In the case of the two formers, at least they have an excuse that most footwear does not come in their sizes.
Does This Remind You of Anything?: Stacy X is the leader of a minority group and calls them to fight them and drop their human names. Charles Xavier (And Magneto) also make codenames up to replace "Human names". The fact Mutants are rounded up in camps.
Pyro's treatment in Ultimates 3. Nearly everyone killed off in Ultimatum may be considered this trope as well, particularly the number of major characters killed in the big flood, Beast and Nightcrawler especially.
Although a minor character, the worst offender in Ultimatum is probably Toad: his death is never shown nor mentioned, we never see the body and the girl he took to safety (Liz Allen, Firestar) is still alive. The only indication we have that he died is the casualty list at the end of Ultimatum #5.
Psylocke was killed in the storyline involving Xavier's son (whose powers involve possessing people and manipulating reality, but the bodies he inhabits are destroyed from the inside out because of his power), but it turned out that she survived by projecting her consciousness into another body. Or at least that's what she claimed. Evidence is starting to point out it isn't her.
Beast was killed in a Sentinel attack. This was a ruse; Fury borrowed him to conduct experiments on the mutant genome. He was Killed Off for Real in the Ultimatum storyline.
Drugs Are Bad: Oh God, Banshee. (Note: There's no mutant called Banshee in this comic, it's a drug.)
Exactly What I Aimed At: During their battle in Las Vegas, Juggernaut taunts Gambit for failing to hit him with his explosive cards... only to realize too late that Gambit's true target was the structural supports of the building behind him.
Fanservice: All the barely-legal mutant boys and girls are dressed in black leather outfits and / or short skirts, and despite not having Most Common Superpower (until Paquette takes over for pencils) they're dressed in obvious poses.
Heterosexual Life-Partners: Xavier and Magneto were this. And how. Xavier left his wife for Magneto, which was a contributing factor to David's rampage. It would be hard not to infer that they were in a gay relationship, but Xavier says their bond was "stronger than love," which seem to rule that out.
Karma Houdini: Just about every member commits terrible acts over the course of the series and save for Wolverine never faces any repercussions. For example:
Cyclops defects to the Brotherhood and takes part in the bombings of the British Parliament and MI6.
Professor X and Jean frequently abuse their powers to their own ends.
Storm even crippled someone and electrocuted a sandbox full of children (off panel).
Averted with Wolverine in that he not only faces retribution for the things he does, but he is even held accountable for things he didn't do. For example Jean threatens him if he ever thinks of her in a sexual way again, and actually follows though with it despite the fact that she was fully compliant in their affair.
Kill 'em All: Of all the Ultimate titles, X-Men got hit the hardest in Ultimatum. The casualty list — which includes Xavier, Cyclops, Beast, Nightcrawler, Wolverine — is probably longer than the list of surviving mutants.
Leaning on the Fourth Wall: Not usually, but in issue #54, where they're taking on Mojo and his reality show, there are a few instances. Apart from in-universe examples of Breaking the Fourth Wall on Mojo's show, there is Dazzler staring straight forward out of the page and declaring the concept to be a "rip-off of The Running Man".
Charles Xavier. Though he claims he doesn't tamper with people's minds, he's shown doing as such repeatedly, especially at first. Subverted in that EVERYBODY knows he does it and question their actions, but when he's out of order, they still do what they think he would've had them do.
Magneto as well, observe him with Polaris in his cell.
The Danger Room allows a few. They face off against Brood, and Wolverine calls them Alien ripoffs.
Nightcrawler enjoys pirate stories, which tie into his swashbuckler 616 incarnation.
Storm's play is called Shadowking, a villain in 616 universe.
Jean sometimes envisions Goblins. Jean's clone in the 616-verse, Madelyne, went mad and became the Goblin Queen.
Post Ultimatum, Kitty Pryde assembles a small army of mutants, labeled with color-themed team names. The ones we hear about are Gold and Blue, harking back to the 616 Marvel universe when the X-Men split up in the '90s.
Nice Job Breaking It, Hero: In the midst of their fight, Gambit grabs the nearby Gem of Cyttorak to charge up as ammo against Juggernaut. It does not have the effect intended.
No Celebrities Were Harmed / Our Presidents Are Different: Although he's never referred to by name, whenever the president appears, his features vaguely resemble those of George W. Bush. His vice president also resembles Dick Cheney. Couple this with when the first books were set (during the Bush administration) and it's no big leap to assume that's the president we're looking at.
Clinton is sometimes mentioned as having been bullied into green-lighting the Sentinel Initiative.
Non-Action Guy: Doug Ramsay is a non-mutant at his school, he's just really smart. He wasn't the only non-mutant; Emma Frost was very proud of the fact that it was human-integrated. He was just the only important one.
Take Up My Sword: Although Jean does not seem to want to do this for Xavier and the X-Men, it seems like she will do so, as Quicksilver is apparently starting a new Brotherhood of Mutants, and has at least successfully recruited Theodore, Liz's brother.
Taking You with Me: It seemed Cable pulled this on Xavier. He didn't. It is however, played straight with Gambit.
Technical Pacifist: Xavier. Notably, members of the X-Men regularly question his policy on this point.
Terminator Twosome: Cable and Bishop, as par for the course. Subverted by Cable bringing his entire team to the past.
There Are No Therapists: You'd think the Xavier institute would have one permanently on remand considering the students that go there. This winds up really bad, in the case of Nightcrawler. Apparently being held captive by Weapon X left him more screwed up than everyone thought, so when he snaps and kidnaps Dazzler, everyone is shocked.
Before that, Shadowcat went the other way and joined Spider-Man's cast, as did Iceman after Ultimate X-Men was canceled. Peter's death is prompting Shadowcat and Iceman to return and bring a friend: the Human Torch, who was in Fantastic Four before moving to Spider-Man.
We Named the Cat Mystique: Xavier owns a cat called Mystique in an anticlimactic extra side story we're shown Emma picked the name after Mystique nearly beats Xavier up.
What Do You Mean, It's Not Symbolic?: In-Universe, Rogue feels this way after encountering first Warren Worthington (whose codename is Angel), and Nightcrawler. It's taken to the extent that, in the Ultimate Fallout comics, she's shown recalling them as one of her "signs" that the Apocalypse is falling for the mutant race.
What the Hell, Hero?: Xavier is on the receiving end of this one a lot. Keeping Nightcrawler alive after he kidnapped Dazzler was enough for her to Rage Quit.
All Your Base Are Belong to Us: Reverend Stryker's death triggers this in the Nimrod Sentinels he takes over with his mutant powers, he pulls this on the entire USA, decimating the already decreased Mutant count
Bittersweet Ending: The World War X arc ends with Utopia victorious, but to do so Kitty had to destroy Tian and couldn't evacuate everyone in time, causing thousands of deaths, the Sentient Seed died, and Kitty feels guilty about her actions.
Boom, Headshot: Attempted on Jimmy by mercenaries and Kitty by a paranoid sniper. Jimmy healed from the wounds, and Kitty ramped up her density in order to simply tank it.
Cain and Abel: Jimmy Hudson and Pietro are half-brothers, with Wolverine sleeping with Magneto's ex-wife, Magda Lensherr, and getting her pregnant. They promptly try to kill each other at one point.
Child Soldiers: During the United We Stand/Divided We Fall Arc and World War X arc.
Civil War: Tian versus Utopia as evolved into this.
Fantastic Racism: Mutants have always been a metaphor for racism, but since Ultimatum, it seems the stories are now specifically addressing the Islamophobia that became widespread after 9/11, with Magneto symbolizing Osama bin Laden.
Karma Houdini: Jean Grey after World War X gets away with just a power limiter on her. Kitty wants to avert this for ordering the attack, but the World Bodies are happy Tian is gone and don't want to police mutant issues at the moment.
Noble Bigot: General Thunderbolt Ross may not like Mutants, but when one of his own attempted to kill Kitty in cold blood he attempted to take the bullet for her. He's doing everything By. The. Book. including giving them a 12-hour grace period before he invaded and ordered them taken alive, as well as retreating once fake Psylocke's influence wore off and giving some parting advice for them to simply live while they were young.
Power Nullifier: After the events of Divided We Stand, Mutants are offered two choices, to take a Power Nullifier and live as ordinary citizens or go onto reservations.
Reed Richards Is Useless: Averted. Kitty intended to show that the remaining mutants were peaceful and willing to contribute to helping humanity, such as making the Sentient Seed, which managed to even Terraform raidated soil.
La Résistance: After the Nimrod breakout, the mutants turn into this even more.
Sinister Minister: Reverend Stryker in this incarnation gears up on man-sized Sentinel weapons and begins to hunt mutants after Ultimatum.
Mach Two, under Wood's tenure, becomes something of a Rule 63 equivalent to Magneto, as the voice of dissatisfaction in the remaining group of mutants and actively even declaring she wants a war, at one point.
Trigger Phrase: Project Mothervine is used on Mutant Sleepers Agents to trigger them into acting. Psylocke did this to Jimmy. Making him eager to start another war with Utopia against the Military, despite knowing they won't survive another war.
Troubling Unchildlike Behavior: Mach-2, who is planning on killing Kitty and assuming control of Utopia. Psylocke has been prodding her into it at least on some part.
Token Evil Teammate: fake Psylocke during the X-Reservation and Natural Resources arc. The bombing of the greenhouse, the splitting of the factions, everything to have other mutants dragged off in chains.
Took a Level in Jerkass: Jean Grey since assuming the mantle of Mistress of Tian, going so far as to start a war between the already dwindling mutant race, bombing Utopia, mind-controlling Jimmy into attacking her own country so she would have a legitimate reason to continue the war, ordering assassinations, and trying to kill her own team.
What the Hell, Hero?: Jimmy to Jean Grey after she starts attacking Utopia and decided to assassinate Kitty Pryde.
