[[folder:Magneto]]
* Magneto is typically portrayed since the 70s as a WellIntentionedExtremist. The occasional writer has instead portrayed him as a loony terrorist, who is only interested in racking up as high a body count as superhumanly possible. In fact, Magneto probably goes through more (and more varied) character derailments than possibly any other non-main-character in the MU.
** Writer Creator/GrantMorrison tried to defend their decision to make Magneto a raving drug-addict who rounded humans up into death camps in ''ComicBook/NewXMen'' by saying that "[[DracoInLeatherPants What people often forget]], of course, is that Magneto, unlike the lovely Sir Ian [=McKellen=], is a mad old terrorist twat. No matter how he justifies his stupid, brutal behaviour, or how anyone else tries to justify it, in the end he's just an old bastard with daft, old ideas based on violence and coercion. I really wanted to make that clear at this time." [[UnfortunateImplications A Jewish Holocaust survivor forcing people into death camps?]]
*** Neither the fans nor the other writers were convinced by Morrison's explanation, and the latter group very quickly {{retcon}}ned the story. Despite the overly convoluted result (the whole thing was Xorn pretending to be Magneto pretending to be Xorn. Oh, and there's ''more'' than one Xorn), this is generally considered (barely) preferable to letting Morrison's characterization of Magneto stand. It should be noted that Magneto, as ''originally'' written, was indeed an anti-human terrorist --it was his transformation into a baby (by his own creation, Alpha the Ultimate Mutant) and his later being aged up again, that cured him of his more extreme tendencies. So Morrison ''was'' right in his assessment of him -- they just failed to consider ''all'' the character development Magneto had since then, or did not properly explain the reversion beyond the influence of alien mind control spores.
*** It also bears noting that in the 1960s, while Magneto's sympathetic backstory had yet to be written, he was a ''generically'' evil villain as opposed to being in it only because he's kill-crazy. Even in the days of MediaNotes/TheComicsCode, he could have ''tried'' to do what Morrison's Magneto did but simply been prevented, but he actually passed up many opportunities for [[KickTheDog puppykicking]]. He felt mutants should rule the world because mutants are more awesome, and so your average Magneto issue involved him trying to recruit the latest newly-discovered mutant and [[BadBoss calling Toad a dolt a lot]]. And ''then'' the '70s come along and he grows into the Magneto we've known for the past 40 years. While other writers have had trouble balancing the "well intentioned" part and the "extremist" part, Morrison's Magneto is Morrison's alone, and when that's coupled with his statement, it really seems to be a TakeThat against a character they personally saw as a DracoInLeatherPants.
*** Depending on how you look at it, the AntiVillain Magneto is a CharacterDerailment of said "generically evil" Hitler-esque Magneto of the '60s -- which would make this a rare example of [[Administrivia/TropesAreTools derailment actually working for the better]].
*** Of course, complicating the issue, Magneto ''is'' undeniably hit with DracoInLeatherPants appeal, causing people to overlook his numerous pre-supposed derailment attempts to provoke a war between human and mutant-kind, the fact that he literally ripped the adamantium out of Wolverine's body and sent the whole of earth into a dark age with an EMP during the "Fatal Attractions" storyline, or, in "Eve of Destruction" the storyline ''right before Morrison's run'', features Magneto crucifying Professor X, forcibly conscripting mutants into Genosha's army by threatening their families, and attempting to slaughter the X-Men en route to declaring a war of extermination on humanity. Not to mention Magneto being an absolute abusive douchenozzle to all three of his children for no good reason beyond “I was trying to toughen you up”.
** Special mention must go to his sudden reappearance in ''Uncanny X-Men'' #500. Not only does he show up and attack the X-Men with apparently nothing resembling a plan or motives (something ill befitting a character who's always been best portrayed as a WellIntentionedExtremist), but it's revealed that not only was he taking orders from the High Evolutionary, he was actually using a mechanical device to replace his lost powers, something that a proud believer in mutant supremacy over the "inferior" humans would ''never do''. Compare his appearance in ''X-Men Legacy'', mere months earlier, where he was portrayed as having no loss of dignity or pride whatsoever post-depowering, and even managed to beat his still-powered former Acolytes without any powers at all, in defense of Xavier. All the while refusing to concede to his former [[TheDragon second-in-command's]] claim that as a human he was no longer the worthy leader of the Acolytes he once was.
*** He's used tech to bolster his powers before.
*** This was because his attack was a distraction for High Evolutionary, who gave him (after their plan worked out) back his mutant powers. So this was just Magneto doing what he must to become once again what he once was. Next time we see him in the series he arrives at a funeral and submits himself to Cyclops, who is one of his main enemies.
*** It may bear noting that Magneto's first attack using his power suit happened in issue # ''500''. It was meant to be a special landmark issue, and it had tons of stuff tacked onto it for no other reason than simple nostalgia: an early scene had the team stumbling into an X-Men themed costume party that showcased about a hundred past and present X-Men in all of their various costumes, and the main plotline involved them duking it out with Magneto and two classic-design Sentinels at the same time (because Magneto and the Sentinels are the two most iconic villains in the X-mythos). It was meant to be a light-hearted break from all the high drama following the events of ''[[ComicBook/XMenMessiahComplex Messiah Complex]]'', and a fond look-back at 500 issues of X-Men. Some [[RuleOfCool dramatic license was to be expected]].
** Joseph the Clone was a very different example of a Magneto derailment that just didn't work. Originally, Joseph ''was'' a younger, regenerated Magneto, but he was so much of a loser that he was {{retcon}}ned into a clone... which was rather pointless given that for almost his entire existence, it was hinted that Joseph could easily revert to villainous form if he ever fully recovered the memories of his previous life. Given how overdone clone plotlines are in the Marvel Universe in general and ''X-Men'' in particular, that would've been a better and simpler way to go.
** An even older example of Magneto's Character Derailment comes at the hands of John Byrne in the mid-1980s. Upset that Chris Claremont's much–beloved revelation of Magneto's backstory had turned Magneto into "a poor man's Dr. Doom", Byrne spent every opportunity during that decade to write Magneto (then a repentant member of the X-Men) as a villain fleecing the heroes by pretending to be one of them. The most egregious examples would be the Byrne–helmed CrisisCrossover ''Acts of Vengeance'', wherein Magneto reverted to his 1960s characterization, joined forces with '''the ComicBook/RedSkull''' of all people (which was later explained in an AuthorsSavingThrow by then–''Captain America'' writer and noted continuity buff Mark Gruenwald as [[TheInfiltration an attempt to get close to the Skull in order to assassinate him]]) and ''X-Factor Annual'' #4, whose back–up story featured Magneto and Dr. Doom comparing notes on their specific [[FreudianExcuse Freudian Excuses]] and Doom theorizing that Magneto '''let his daughter Anya die so he would have an excuse to murder humans at will'''.
*** Much of Magneto's out of character behavior during this period was eventually [[AuthorsSavingThrow explained]] by Chris Claremont as a literal example of WithGreatPowerComesGreatInsanity — literally, as Magneto exercises his powers more and more, they degrade his sanity and force him to experience more and more severe bouts of megalomania, thus explaining his original 1960s characterization and his later increasing insanity after his powers and sanity were reset by Alpha the Ultimate Mutant. It's an explanation Claremont in particular has returned to several times since when he has written the character.

[[folder:Storm]]
* If you want to keep a good amount of ''ComicBook/XMen'' fans happy, ''don't'' talk about the way Storm's being written in ''ComicBook/BlackPanther''. Having her declare her strong love for one of Marvel's few other black characters out of Reginald Hudlin's desire to [[strike:get a TokenRomance going]] snag a hot black babe for his badass black CanonSue was bad enough. Throwing away most of the strong characterization that made her a leader of the X-Men many times over to turn her into a love-struck woman whose major concern is her marriage and her husband? (At least she's back with the X-Men, having grown bored with queening.)
** Not to mention that Storm is someone who was once so into female empowerment that she defied all stereotypes by ''getting a mohawk''... and is now content to play the good wife to a man who is still keeping his royal harem. Or that she once berated Dr. Doom for the sheer amount of helpful technology he was keeping from the world, but seems perfectly content to let Black Panther hoard every bit of technology, including cancer cures, from everyone that's not Wakandan. Would "pot and kettle" be a little too [[DarkerAndEdgier edgy]] a punalogy to invoke?
** Getting the Mohawk (or rather, the entire makeover and outlook change more notable for including the Mohawk) was, itself, a moment of pretty massive character derailment, though at least her teammates (especially Kitty) pointed this out and an attempt was made to explain it (even if it basically amounted to "spent the night partying with a free spirit and liked her style").
** Another thing to keep in mind is that Storm has a long romantic history with Forge, which left Storm a bit [[BrokenBird damaged in the relationship department]] after he backed out of his own marriage proposal. To Black Panther's proposal, she just says 'Yes'.
** Not to mention, the "Wedding of the Century" StoryArc ripped Storm right out of the X-Men with little to no preparation - she went from a successful leader of an independent band of heroes, having the government approval to kick the ass of any supernatural threat and all but in an actual relationship (with Wolverine, of all people) to being pretty much everything mentioned above.
** Also, speaking of Wolverine, notice how he is being treated in Hudlin's writing. You would think that man is trying to [[YouAreWhatYouHate compensate for something...]]
** And as a final kick in the gut, seeing Storm as the ultimate heroes-do-not-kill person say "Stand down or be ''destroyed''" to a mob of '''civilians''' is rather painful.
** Thankfully for fans who hate T’Challa being married to her she has divorced Black Panther and is now back with the X-Men.
* Ironically in more recent comics the attitude has changed with the majority of fans actually being more accepting of Storm appearing in T’Challa comics. Though is in part due to ''ComicBook/XMenTheKrakoanAge'' being such a BrokenBase (and Storm’s choices wherein being considered by some to be character derailment itself) that Storm occasionally hanging out in Wakanda with Black Panther as AmicableExes is so minor in comparison.

[[folder:Cyclops]]
* With Scott Summers a.k.a. Cyclops, it's hard to decide where to begin. First off, Cyclops had always been a more or less admirable hero, and the contrast to, say, Wolverine (the X-Men's resident AntiHero during the 80s). Aside from that, he was romantically involved with Jean Grey until her death in ''ComicBook/TheDarkPhoenixSaga''. Afterwards, Cyclops was shown to be drifting away from being a superhero: he quit the X-Men, settled into a normal life in Alaska, met a woman named Madelyne Pryor who bore a strong resemblance to Jean, married her and had a son. This was in keeping with writer Creator/ChrisClaremont's intention for ''ComicBook/UncannyXMen'' to have LongRunnerCastTurnover where team members would be able to move on to civilian life. Then the spin-off series ''ComicBook/XFactor'' began, which reunited the original five X-Men including a newly resurrected Jean – so naturally Scott and Madelyne spontaneously developed marital problems and he began yearning to be a superhero again. Upon hearing that Jean has come back to life, Cyclops immediately walked out on his wife and newborn baby to go meet her – he then spent two weeks moping around in New York without ever attempting to contact her, then over the next several days ended up joining the X-Factor team and ''still'' not going home or trying to contact Madelyne at all (meanwhile she is seen alone at home in Alaska looking miserable as an X-Factor ad plays on TV). He then let ''even more'' weeks pass until he ''finally'' decided to give her a phone call, only to find the phone had been cut off – and interpreted that as meaning Madelyne had moved away, letting ''even more'' time pass until he made more of an effort to find her via their friends and discovered that his wife and son had actually gone missing. And throughout all this time he [[CannotSpitItOut never admitted to Jean]] that he was married, only coming clean once she figured it out for herself. Many people including Claremont cried foul at turning Cyclops into a [[DisappearedDad deadbeat dad]] and a would-be cheater, especially as he had been such a morally upright hero before – a RetCon a few years later blamed his behaviour on Mr. Sinister's mental influence, which never really satisfied readers for how obvious it was as an attempted AuthorsSavingThrow. Meanwhile, Madelyne resurfaced as having been a target of attempted murder by the Marauders, went with the X-Men to Australia, and then suffered CharacterDerailment of her own, eventually changing from a noble and courageous young woman to an evil psychotic – from there, she became one of the principal villains in the ''Inferno'' crossover, and then was killed off. Although Scott fortunately did not marry Jean until years after that, they had resumed their relationship by the time Madelyne emerged as a villain. The baby was raised by Scott and Jean and eventually sent into a Post Apocalyptic Future and grew up to become ComicBook/{{Cable}}. This lasted until his ''further'' derailment during Creator/GrantMorrison's run on ''New X-Men'', where, after he had recently been resurrected from being merged with Apocalypse, Cyclops' relationship with Jean decayed, he ended up being the target of Emma Frost's affections (who herself was derailed into a SpoiledBrat, when she spent the '90s as TheAtoner), who abused her position as Scott's therapist to have a psychic affair with him. Jean is then unceremoniously killed again, after which Cyclops considers leaving the team after rejecting Emma. However, it is revealed that this would cause an apocalyptic future, which can only be prevented (in an absurd Deus Ex Machina) if Scott and Emma end up together. This in turn leads to future Phoenix going back in time and psychically manipulating Cyclops to get together with Emma and culminates with Cyclops making out with Emma on his dead wife's grave; depending on YMMV, could be considered forcing him into a relationship with a previous abuser. Then after the mutants are depowered, he is now "suddenly" willing to kill his enemies off.
** And ''fire'' Professor Xavier.
*** That is supposedly justified because of the things Xavier has done, except those things ''themselves'' are derailment. He has been turned into a Magneto-esque "I'll run over ''anybody'' for my good cause and you are supposed to forgive me because I look sad for a panel or two when called on it" sort of character. Among the things he has been {{Retcon}}ned as doing: The Danger Room was ''sentient'' and he deliberately left it in AndIMustScream condition rather than go back to the previous version? And using MindRape to cover up his recklessly assembling and losing a half-trained second team between the original X-Men and Storm, Wolverine, and company.
** ''ComicBook/XMenTheKrakoanAge'' managed subvert this and give Scott CharacterRerailment.
* Ultimate Cyclops got a bad case of this when he left the team to join Magneto. His reason? He saw ultimate Logan and ultimate Jean making out. That's it. He left the closest thing he had to a family to join a genocidal supervillain...because he saw his sort-of girlfriend making out with someone else. Nothing else. Sure, he tries to pretend otherwise, but nobody buys it.
[[/folder]]

[[folder:Wolverine]]
* Wolverine is generally a jerkface. [[JerkWithAHeartOfGold It is part of his charm]]. But he is loved for the fact that, while a jerk, he is willing to realize when he is in the wrong and does care about his team and friends. Yet, in present comics, under the hand of Jason Aaron, this has been misrepresented as HolierThanThou, with him acting like a complete unrepentant asshole to Cyclops because he disagrees with him. This is seen as justified because he is right, despite massive flaws in his arguments. In Logan's defense, he, along with many other heroes, DOES have a few good reasons to be angry at Cyclops. After all, Cyke IS partially responsible for Professor X's death and he had the bright idea to welcome back the Phoenix Force to planet Earth, [[WhatTheHellHero even after everything it did]] to him, his ex-wife and his friends, thus almost dooming the Earth. That being said, he constantly argues about keeping the younger students away from the battlefield to preserve their innocence, which wouldn't be so bad had it not been for the fact that mutants were facing extinction and needed to be able to defend themselves. When this is no longer the case, he argues about Cyclops taking new mutants out into the field, despite the fact that these ones are all much older than the usual recruits. The worst part is that Cyclops barely bites back at first, with him generally giving counter-arguments to these claims that are tossed out or ignored. Eventually, Cyclops, quite rightly, points out Wolverine's hypocrisy, while Wolverine just shrugs these off with "that doesn't matter, you are still wrong".
[[/folder]]

[[folder:Emma Frost]]
* Grant Morrison's derailment of Emma Frost in ''ComicBook/NewXMen''. She was not a SpoiledBrat who manipulated others just because of some issues she had in her past. She was manipulative as a villain because of her ambition and callousness. Yet it turned out she was not beyond caring when finding out what happened to her students, after she came out of a coma, and that put her nearly in the DespairEventHorizon. Then she became TheAtoner. Morrison basically ignored all that, and even had her being a sex therapist, despite her profession of being a teacher.
** While her change in personality ''could'' be justified by her witnessing Genosha's massacre and spending several days buried alive, in-story it was never brought up and later writers treated her as if she has always been like this and her Atoner period in ''ComicBook/GenerationX'' [[CanonDiscontinuity seems to be forgotten entirely]]. "Sex therapist" is a complete AssPull, though.
** What makes it worse is when you realize exactly what a sex therapist is. She essentially convinced Cyclops, who was in fact experiencing a mental breakdown from his time possessed by Apocalypse, that the best way to deal with his issues is to sleep with her. That, as well as being absolute bullshit, is highly ''illegal'' and would be classified as ''rape''. Yet, instead of being punished for taking advantage of her position and Cyclops' mental state, her actions are handwaved because she loves him (as per Rape is Love) [[StrangledByTheRedString apparently]], and she ends up [[KarmaHoudini as co-headmistress of the school and co-leader of the X-Men]]. It is sickening especially when you know how she used to be.
** Her derailment was eventually retconned by Creator/JossWhedon in ComicBook/AstonishingXMen; it was all because of Cassandra Nova's influence on her mind.
* The attempt at making her a villain again after ComicBook/DeathOfX did not go over well at all. Most people found it incredibly unconvincing and forced as she had essentially been either an anti-hero at worst or full blown hero for most of the preceding twenty years (in fact, about double the time she'd spent as a villain, given that she spent the first few years of the '90s comatose). Fans mostly tried to ignore it and half time it felt as if the writers themselves wanted to downplay it. It mostly felt like a decision being forced by an X-Men editor who admitted that he never bought into the idea of heroic Emma, since the only story with her he'd ever read prior to ''New X-Men'' was the ''Dark Phoenix Saga'', and had never actually read ''Generation X'', where all of her previous development had taken place. Also in part because he was an admitted Scott and Jean shipper.

[[folder:Other]]
* Forge in the "Ghost Boxes" arc of ''[[ComicBook/XMen Astonishing X-Men]]'', written by Creator/WarrenEllis. Suddenly for no particular reason Forge is completely insane and decides to save the Earth from extra-dimensional invaders by... sending his friends to the other dimension and then killing them. And then Beast and Agent Brand blow up the other world with a laser after Forge just goes "Screw it." and opens up the Ghost Box risking all life on Earth. And then he whines to Storm for rejecting him and stays in his complex as it blows up. Character Derailment isn't a strong enough term for what happened to Forge.
** Ellis was not very familiar with X-Men history and asked Marvel editors for help. They gave him a bunch of comics. The problem is that in most of them Forge's mental shape wasn't at his best. We can assume that Ellis didn't do his homework, but really wanted to. Though, even during those issues Forge wasn't anywhere near that crazy, so some of the blame still falls on him.
** In Ellis' ''Astonishing X-Men'', a much bigger character derailment happens with practically the whole team. In previous stories, the X-Men (like most Marvel superheroes) had always [[ThouShaltNotKill tried to avoid killing their enemies]], using lethal force only if there was no other option. However, in Ellis' X-Men the team has suddenly adopted a different morality, so they find it okay to murder a villain even after he has been defeated and poses no threat to them. Even worse, in ''Astonishing X-Men'' #30 [[spoiler: the X-Men have no problem with firing a massive laser through a dimensional portal into an alternate Earth. According to Beast this laser destroys everything within a 10 mile radius, presumably killing a whole lot of people. The reason for this rather brutal display of power? Beast ''assumes'' (but does not know for sure) that this alternate Earth is a corrupt one, populated by evil mutants. So it is perfectly possible the laser might have killed lots and lots of innocent people, not just some bad guys. Talk about questionable morality!]] Ironically enough, the only character to protest against this new stance on killing is Storm, even though in ''Uncanny X-Men'' #170 [[spoiler: (where Storm duels with Callisto to save Angel's life)]], #216 (where she is ready to kill Crimson Commando and order the death of Stonewall at the hands of Wolverine, and is serious about it), and #325 (where she stops Marrow, by ripping out her heart; [[DeathIsCheap Marrow was revealed to have two hearts and came back]]), she was shown as the ''only'' X-Man capable of killing cold-bloodedly in order to save the life of a team member.
*** #170 was an exception, not the rule; and could in fact be considered Character Derailment itself.
** Also happened in ''ComicBook/{{Nextwave}}'', due to RuleOfFunny. Ellis intended for ''Nextwave'' to be Non Canon, but it ended up being so popular writers have tended to [[CanonImmigrant Canon Immigrate]] the changed characterizations.
** Not to mention what happened to Colossus' character in order to [[DieForOurShip cement the Pete Wisdom/Kitty Pryde pairing]]. Even for those who love Ellis, the issue reads like bad [[RonTheDeathEater Harmonian fanfiction]].
*** And then Jason Aaron one ups Warren Ellis by turning Colossus to a Phoenix-powered StalkerWithACrush to push [[DieForOurShip his Iceman/Kitty Pryde pairing]].
* Proof that Jason Aaron should not write X-Men is the fact that he has ''all'' the X-Men under his wing call Cyclops (and his friends) out on anything he does and constantly pick fights with him, even if the situation calls for them to put aside their issues, most notably during ''Battle of the Atom'' and following issues. Even when they have got the future Brotherhood of Mutants on the loose and Cyclops is telling them they should focus on finding them, Storm feels the need to accuse him of being a supervillain. Both Kitty and O5!Scott pick arguments with Magik and Present!Scott respectfully, even though the Bendis issues establish that O5!Scott is coming around to understanding Present!Scott, as well as showing that Kitty and Illyanna are still really good friends. This was not just derailing canon characterization, this was derailing the characterization characters expressed mere ''issues'' ago, to the point it seems he just doesn't bother reading what the other guys are doing.
* Even Creator/ChrisClaremont may be guilty of this -- his ''X-Men: Die by the Sword'' has Merlyn teaming up with Mad Jim Jaspers to kill his daughter and take over TheMultiverse, despite that, while being a ManipulativeBastard, Merlyn was always concerned about the good of TheMultiverse and almost died to save it from Jaspers. Even when it was later revealed he faked his death and was manipulating people from the shadows, he was still doing this for the greater good; in this series, however, he is just plain evil and mad. Creator/PaulCornell had solved this problem by claiming Merlyn went insane and having his body hijacked by one of his alternate selves (Merlyn was the nexus of all Merlins in TheMultiverse), who happened to be from Marvel's ''Series/DoctorWho'' comics.
* All of the original ''ComicBook/NewMutants'' team has suffered from this at one time or another since leaving the book; particularly noticeable with Cannonball (from competent team leader and commando to "Golly, shucks y'all" junior member on X-Men) and Sunspot (hot-blooded but good-natured brawler to occasional goofy-ass moron).
** Rahne got one in the second ''New Mutants'' series, losing her trademark accent and becoming a bad-ass biker-girl who made out with a ''student'' at Xavier's. Old-school fans were ''not'' impressed, and the derailed character was removed from the book quickly, and brought back to her old self elsewhere. CanonDiscontinuity at its most extreme.
* Bishop was given one of truly epic proportions. At the end of the ''[[ComicBook/XMenMessiahComplex Messiah Complex]]'' storyline, he betrayed the X-Men and his whole reason for living suddenly became killing a newborn mutant girl because he thinks that she is the antichrist who destroyed his home future. Despite the fact that it went right against his whole previously established history where in his timeline, the X-Men died in battle with Onslaught and ComicBook/HouseOfM did not happen. So he went from a pretty heroic guy to a guy who literally casually commits ''mass genocide'' and kills anyone in his way. It took ''years'' for him to return to his original characterisation.
** Said return first had an attempt to explain away his actions by saying that he was being possessed by the Demon Bear when he performed them. Nobody seemed to buy this and by the time he showed up again it seemed that the chosen solution for how to fix Bishop turned out to be [[CanonDiscontinuity ignoring it completely, never addressing it and doing everything short of outright pretending it never happened]].
* Even their alternate versions aren't safe from this. When ''ComicBook/UltimateXMen'' changed writers to Vaughan, most characters practically became clones of their main universe selves. Professor Xavier was the most heavily affected, suddenly claiming that he would never read anyone's mind without permission, while previously, he read minds for fun.
* The Juggernaut has gone through some weird times. Him connecting to kids in [[ComicBook/UncannyXMenChuckAusten Chuck Austen's run]] could be seen as CharacterDevelopment, but acting like a mopey teenager and enduring endless verbal abuse from other X-Men without any comeback is less so. Heck, in the first story by Austen to feature Juggernaut, he is willing to commit (non-heroic) suicide for... some reason. Portrayals since have bounced back and forth between AntiHero, TheAtoner or just a guy who likes to bash stuff. And then there is his intelligence, which varies between DumbMuscle and a smart guy whose father was a nuclear scientist.
** Perhaps even bigger case of derailment can be attributed to Cyttorak himself, the source of Juggernaut's power. He was initially the mysterious god of another dimension who did not care much about good or evil on Earth. When Cain upon their first personal encounter tried to kill Cyttorak, he reacted with quaint amusement. These days Cyttorak is portrayed as a demon lord, who weakened Cain's power because he was displeased about him acting heroically. And now that Colossus is the Juggernaut, Cyttorak has said that he likes having a hero as his avatar, since what he ''really'' wants is for the Juggernaut to cause destruction, and whether it is due to good or evil intentions is irrelevant. Bwahuh?
* ComicBook/{{X 23}}'s first two appearances in ''ComicBook/AllNewXMen'' receive a significant amount of flak for this. While Laura's SpockSpeak has always been subject to DependingOnTheWriter to varying degrees, she has nonetheless been consistently portrayed as TheStoic and more formal than her peers. In ''All-New X-Men'', readers found her personality and behavior excessively un-Laura-like in #20. In particular, they point to ''how'' talkative she is compared to her normal depiction as TheQuietOne, and the significant amount of slang in her dialog. {{Word Of| God}} [[Creator/BrianMichaelBendis Bendis]] states that her behavior in the series is because [[ComicBook/AvengersArena Murderworld]] and her subsequent torture by the Purifiers before she turned up in Miami were the events that finally pushed her beyond the point at which she can cope with all that has happened to her. While accepting that it is believable that Laura has been pushed past her breaking point, [[FanonDiscontinuity some fans tend not to agree with him on the sudden personality shift]]. [[BrokenBase Other fans believe that this personality shift works for her because it gives her a more mature, less "emo" personality, which makes sense because she is not a teenager anymore.]]
* Rick Remender's handling of characters in ''ComicBook/UncannyAvengers'' has been called into question:
** After Wanda Maximoff returns in ''ComicBook/AvengersTheChildrensCrusade'', Rogue is the first and only X-Man to be somewhat sympathetic towards her. In UA, she hates Wanda with a fiery passion. While this could be justified with Xavier's death, fans generally don't buy that explanation and just feel Remender really needs a ConflictBall between members of the team.
** A clear-cut example would be Cyclops telling Alex Summers that he "learned better" than to fight for Xavier's dream. All other series he has appeared in have him fighting for Xavier's dream, just in a slightly different way.
* Before his coming out, Bobby Drake had a girlfriend named Opal, at first all lovey-dovey but generally level-headed. After a story in which Mecha-Yakuza tried to kidnap her because she was a hidden Yakuza princess, an honor spot by her fallen kidnapper had her denouncing Bobby as not understanding honor. This started her decline, and every next time they met, she laid into him and complained bitterly when he would have to rescue her from X-Foes seeking to harm their loved ones. It finally culminated in a mini-series where she allied with some evil corporation to pass off a clone of Drake's as their son, for reasons. Add to all this, she laid into him for being an irresponsible boyfriend and father, despite never being told about a kid who did not really exist. She became the type of character who you wished would be right at the meeting place as Earths 616 and 1610 collided.
* For [[ComicBook/UncannyXMenChuckAusten his run of]] ''ComicBook/UncannyXMen'', Creator/ChuckAusten needed an excuse to break up Havok and Polaris so that he could get Havok together with his PuritySue, Nurse Annie. So practically overnight, Polaris became a complete and total {{Yandere}} who snapped at anyone who so much as got within twenty feet of Havok, yet was flirting with the strippers at her own bachelorette party, while everyone talked about how fucked up she was and poor Havok for having to deal with her. And when Havok, (who, as it turned out had spent months on "psychic dates" with Annie while in a coma and engaged to Polaris) dumped her ''at the altar'' for Annie, Polaris snapped and tried to kill them both, resulting in her being taken down and imprisoned by the others. Thankfully, Annie was PutOnABus, and the whole thing was quietly handwaved away as having been unwitting psychic interference by her young son, who had (for some reason) picked the comatose Havok as a perfect new father.
* The veteran villain Toad has suffered from this in the last couple of decades. He started out as the least competent and dangerous member of the original Brotherhood of Evil Mutants, but he was developed over the years into a GadgeteerGenius and a semi-competent leader for villain teams. At some point all his character development went out of the window, and he has been depicted recently as a janitor, a lowly servant, and a willing victim for the schemes of various heroes and villains.
