Set in the alternate [[MarvelComics Marvel]] universe of American-created manga ''X-Men: Misfits'', [[http://www.fanfiction.net/s/6786558/1/Mutatis_Mutandis Mutatis Mutandis]] by [[http://www.fanfiction.net/u/2359030/Artemiss_Liege Artemis's Liege]] has a very similar premise to the manga itself: the telling of how a new girl adjusts to the Xavier Institute, which was renamed "Xavier's Academy" by the manga.

But this time, it is [[DeadpanSnarker Rogue, A.K.A. Anna Marie]], who is the newcomer, and now along with Kitty Pryde, they are only two girls in the student body. Brash, judgmental, and somewhat self-absorbed, Anna is far from a righteous herald of justice, nor is she a typical teenage girl who's excited to be in a school populated mainly by boys. She also has a knack for getting into trouble.

Luckily for her, the Xavier's Academy teachers are a bit distracted: the public is just beginning to discover mutants, which contributes to the ComicBook/CivilWar that is raging in the background, ignited by the [[SuperhumanRegistrationAct Superhero Registration Act]].

The story opens with fifteen-year-old Rogue being mind-wiped on Mystique's orders in order to be a mole at the Xavier's Academy. Anna now believes herself to be a normal teenage girl, albeit rather sarcastic and dismayed at the prospect of starting a new school.

Mainly referenced as her birth name of Anna Marie, she has already obtained [[MsMarvel Ms. Marvel's]] Kree abilities and is able to touch other people. However, despite her abrasive attitude and sullen demeanor, Anna feels as though she is obligated to live up to Ms. Marvel's legacy. A reoccurring theme is is her inability to move forward from the incident between herself and Ms. Marvel.

The story appears to revolve around her introduction and adjustment to Xavier's Academy while also coping with Ms. Marvel's superhuman abilities [[spoiler: until it is revealed that the Kitty Pryde is actually Copycat and the real Kitty is a mutant subject at a scientific research facility.]]

The fic is currently unfinished.

----

!!''Mutatis Mutandis'' contains the following tropes:

* TheAce: Mindwiped!Anna regards her aunt Raven (Mystique) as this. She may look to Raven as a substitute mother, which has elements of [[WellDoneSonGuy Well Done Daughter Gal]].
* ActionGirl: Anna, by Chapter Fourteen.
* {{Adults Are Useless}}: Anna thinks this way. She rarely regards adults as capable of understanding her actions, nor does she ever go to them for help.
* AmericanAccents: Several characters raise the observation that though Anna is from the South, she doesn't have a Dixie accent. This is because Anna absorbed Ms. Marvel's psyche and with it, her Northern speaking style. Anna worries that this means she's losing herself.
* AmnesiaMissedASpot: Anna paints her fingernails while spending time at the Brotherhood base. Mystique has her mindwiped to forget the Brotherhood, so Anna's memories of the base are completely erased. But Anna is still wearing the fingernail polish, and she can't remember painting her nails, which puzzles her.
* {{Anime Catholicism}}: Invoked. Despite being Catholic himself, Santo assumes all nuns are the type he's seen in ''LightNovel/TrinityBlood''.
* AnimeHair: Bobby's blue, spiked hair, according to Anna.
* ApatheticTeacher: Mr. Proudstar seems somewhat grouchy and has a general disdain for the students.
* {{Ascended Extra}}: The author explains in a note at the end of one of the chapters that initially Jean-Paul was supposed to be Anna's snarky best friend and moral compass but realized he was described in a way that did not lend himself to such a role. Thus, Victor became the [[RedOniBlueOni blue oni to Anna's red]].
* {{Author Tract}}: One examining the treatment of race and sexuality on {{Glee}} and another running one directed at the X-Men manga itself.
* {{The Beautiful Elite}}: The Hellfire Club, but Emma Frost dismisses them as mostly nouveau-riche. Also, Jean-Paul and Jeanne-Marie, along with their family.
* {{Bi The Way}}: Perhaps. Scott Summers draws a comparison between Jean-Paul and bisexual Peter Allen of ''The Boy From Oz''.
* {{The Chessmaster}}: Mystique.
* {{The Cameo}}: Comicbook/{{Daredevil}}, Comicbook/TheSentry, Arachne, and [[Comicbook/SpiderMan Carlie Cooper]].
* {{Canon Foreigner}}: Bella, Anna's young, blonde stepmother who loves fashion. Never appears, but mentioned several times.
* CatholicSchoolgirlsRule: Subverted by Anna: she hates the uniforms of both her schools, and [[TakeThat is just grateful that the Xavier's Academy uniform is not a {{Sailor Fuku}} out of some ridiculous American manga.]]
* {{Deadpan Snarker}}: Anna and Victor.
* DrivenByEnvy: Emma convinces Anna to become her protege by mentioning Kitty Pryde and waxing poetic about Kitty's potential.
* [[FanNickname Detractor Nickname]]: After Nurse Annie- yes, [[CreatorsPet that]] [[TheScrappy Nurse]] [[FanonDiscontinuity Annie]], scorns the idea of anyone ever dating the mouthless Jono, Anna refers to her as "Nurse Anthrax."
* [[DoesNotKnowHisOwnStrength Does Not Know Her Own Strength]]: Anna. [[spoiler: This leads to an instance where she tries to give someone a firm shove and ends ups knocking the wind out of them, and when she savagely beats several Pro-Regs, losing herself in rage.]]
* DressingAsTheEnemy: Anna, when she goes "undercover" in New York City, in order to check if Ms. Marvel is still comatose. [[spoiler: She is. But now, Karla Sofen, a "cape-killer" for the Pro-Regs, has adopted her image.]]
* EarlyBirdCameo: Jono and Remy appear in Chapter Six as students in the cafeteria, while Josh shows up in Chapter Seven as a student in the hallway.
* [[EmotionlessGirl Emotionless Boy]]: Jean-Paul is constantly described as "devoid of emotion" unless he is in Manuel's presence. Since Manuel is can control other people's emotions and possibly has feelings for Jean-Paul, this has certain connotations.
* [[EstablishingCharacterMoment Establishing Character Chapter]]: Chapter One, for both Rogue and Mystique. Rogue as a teenagerwho genuinely regrets maiming Carol Danvers despite her bad attitude , and Mystique as a manipulative, cunning agent who isn't afraid to use others for her own means.
* {{Even the Guys Want Him}}: Jean-Paul is hinted to be the subject of Manuel and Quicksilver's affections, [[spoiler: and also may have something going on with Logan.]]
* EveryoneHasStandards: Even in all her surliness, Anna is outraged by Nurse Annie's cruel comments toward Jono.
* {{Exact Words}}: Anna uses this to find a loophole in the school dress code.
* FanHater: [[InvokedTrope Invoked in the story itself]]. Anna, of SillyLoveSongs, the color pink, and anything feminine that's not also considered mature and sophisticated.
* {{Girls Love Stuffed Animals}}: Some do- Kitty has several plush toys in their room, but Anna scorns them and thinks Kitty is immature and "tacky" for owning them.
* GossipyHens: The Xavier's Academy students.
-->'''Manuel''': One of Jamie's dupes overheard Ms. Munroe telling Ms. Grey, who told Bobby, who told Julio, who told Scott, who told Kurt, who told Shola, who told me.
* {{Grumpy Bear}}: Kurt.
* HotTeacher: Emma Frost and Sam Guthrie. The former even offers Anna the chance to start an affair with the later.
* IAmNotPretty: Anna feels this way, mainly because she is constantly comparing herself to other women.
* {{I Just Want To Be You}}: Anna towards Ms. Marvel, as some weird method of atonement. She recognizes how this strange this is.
* {{Ice Queen}}: Emma Frost.
* {{Im Not Here To Make Friends}}: Anna's general attitude.
** She also has strong elements of {{Jerkass Facade}}, more than likely due to loneliness and her self-loathing and guilt about Ms. Marvel.
* {{Kick The Dog}}: Nurse Annie's mockery of Jono's mutation while she know he's within hearing range.
* LaserGuidedAmnesia: Jason Wyngarde's mindwipe of Rogue as per Mystique's orders.
* {{Loads and Loads of Characters}}: Ye gods. The main players of this fic are Anna Marie and Mystique. At the school, Anna's new friends mainly feature Jean-Paul Beaubier, Manuel de la Rocha, Doug Ramsey, David Alleyne, Santo Vaccarro, and Victor Borkowski. Other important people include Kitty Pryde, Emma Frost, and the Hellfire Club. Not to mention the various superheroes in the Civil War and the Brotherhood of Mutants.
* {{Meaningful Name}}: Anna's surname "Keller" is very similar to "killer." Anna nearly killed Ms. Marvel.
* {{Meekness Is Weakness}}: Anna thinks so, and often attempts to be abrasive in order to show people that she's no pushover.
* {{Missing Mom}}: Anna has no idea who her mother is, nor has she ever had any contact with her.
* {{Mistaken For Gay}}: No one is quite sure of the sexualities of the Hellfire Club members. They're a group of teenage mutant boys who think that they're superior to everyone else, enjoy fashion and inflating each other's egos, and for whatever reason, they keep lucha libre masks and leather bodysuits in their costume.
* {{My Friends And Zoidberg}}: The author refers to Anna and her friends as "our heroes and Jean-Paul" in an author's note.
* {{Morality Pet}}: Manuel, who can be outright vicious, seems to have a soft spot for Jean-Paul and is often shown smiling at him.
* MythologyGag: All over the place.
** "What's a magneto?"
** One of the plush toys on Kitty's bed is in the shape of a purple dragon.
** [[ComicBook/CivilWar Anna reads an editorial by Sally Floyd, who is lambasting CaptainAmerica for not adding her as a friend on MySpace.]]
** "Mr. Logan is the best at what he does . . . and what he does isn't very nice."
** Logan's cowboy hat, which he's been pictured wearing in the comics from time to time.
** Emma Frost thinks Anna's codename should be "Negasonic Teenage Warhead."
** Whenever someone says the name 'the Hellfire Club,' I picture a bunch of mutants dressed up as eighteenth century British aristocrats, basically operating as the mafia, and referring to one another with chess motifs."
* {{Naive Newcomer}}: Subverted, Anna is very cynical.
* {{Narcissist}}: The Hellfire Club is full of them, and Jean-Paul is one, too, according to Santo.
* {{Narm}}: Invoked by the writer, who disliked the manga and intentionally has the Hellfire Club use the most ridiculous lines of dialogue from the book in order to [[LampshadeHanging lampshade]] its stupidity.
* NiceGuy: David, Shola, and Victor are by far the nicest characters. Julio seems to be one, too.
* {{Nice Hat}}: Logan wears a cowboy hat as he instructs the combat class.
* {{No Good Deed Goes Unpunished}}: Anna's powers activated as Ms. Marvel was trying to rescue her from a supervillain attack, leading Carol's coma. This is a major sourse of guilt for Anna.
* {{No Sense of Personal Space}}: Emma is constantly draping herself all over her student Anna, much to Anna's puzzlement. This is probably Emma's way of indicating that she can do whatever she wants with Anna.
* {{Noodle Incident}}: We don't know what happened between Kitty and Manuel, only that he really hates her.
* {{Not As You Know Them}}: Here, Anna is the younger sister of Julian Keller, and that is stated not to be their true surname, instead used to disassociate themselves from their millionaire father. Mystique masquerades as Anna's aunt, the half-sister of her {{Missing Mom}}. She is also best friends with [[ComicBook/AlphaFlight Jeanne-Marie Beaubier]] and attended the same boarding school until Anna transferred to Xavier's Academy.
* {{Not What It Looks Like}}: Mr. Rasputin catches Anna walking into the mens' dorms, but it's her first day; she's actually very lost.
* {{Obviously Evil}}: [[spoiler: Chapter Ten opens with the Pro-Regs going about their daily routine: Reed Richards is experimenting on Goliath's corpse, condoned by all others, while he and Tony Stark discuss how much of a traitor SpiderMan is for not helping them imprison rebel heroes in the Negative Zone.]]
* ParentalNeglect: Anna barely knows her father at all and her mother is gone, while Jean-Paul's parents hired someone to manage his and Jeanne-Marie's lives because they didnít want to be bothered.
* ParentalSubstitute: Mystique/Raven for Anna.
* PokeThePoodle: Wealthy, beautiful Jean-Paul rejects the offer of membership to the Hellfire Club, a group of wealthy, beautiful male mutants. They warn him that he's hanging out with the wrong people and tell him both he and his group of friends will regret it. And then they retaliate by putting a red shirt in the washing machine with his friend Victor's white clothes.
* {{Positive Discrimination}}: One cannot help but notice that Victor is gay, and he is the most compassionate and morally sound character. Also, David and Shola are African-American, and both are portrayed as very polite and avid students in contrast to the rest of the cast, though David is implied to hack computers in his spare time.
* {{Pride}}: '''Anna'''.
* {{Real Women Never Wear Dresses}}: One of Anna's primary flaws is her belief that open femininity shows weakness. However, she also dislikes Storm's mohawk look, but that's because Anna finds it unprofessional that a teacher is dressed like a {{Biker Babe}}.
* {{Retcon}}: Many aspects of the manga are revised or outright ignored.
* {{The Reveal}}: [[spoiler: The Kitty Pryde at Xavier's Academy is actually Vanessa Carlyle, A.K.A. Copycat.]]
* RichBitch: Scott's opinion of Anna.
* {{Rummage Sale Reject}}: When Anna goes "undercover" as Ms. Marvel in the middle of the Marvel Civil War war zone, she wears a modified leather bodysuit from the Hellfire Club's fashion closet that is hastily fitted for her by Jean-Paul (who does not know how to use a sewing machine but has super-speed and therefore make quick modifications), along with a pair of her own Hot Topic-esque knee-high combat boots.
* {{Shown Their Work}}: The description of Central Park is fairly accurate.
** The author is obviously familiar with the MarvelUniverse at large as well.
* {{Skewed Priorities}}: Anna, Victor, and Jean-Paul are trapped in war zone, facing an armed [[ThePunisher Punisher]]. Rather than help explain the misunderstanding, Jean-Paul begins texting on his cell phone.
** Not texting for help, either. Just texting for entertainment as a gun is held to his face.
* {{Smug Super}}: All of the Pro-Regs.
* SternTeacher: Ms. Munroe (Storm), but justified: Anna is constantly trying to undermine her authority by evading the rules through {{Loophole Abuse}}.
* {{The Stoic}}: Jean-Paul. Anna tries her best to be this as well, but fails due to her love for snark.
* {{Straight Gay}}: Victor and Jean-Paul, though the latter may not actually be gay. He was never stated to be such [[spoiler: and the other students believe he's sleeping with [[BiTheWay Logan AND Paige Guthrie.]]]]
* TakeThat: When his parents gave very good-looking yet lethargic Jean-Paul a religious medal for his commencement of moving up to high school as part of his school's tradition, he was presented with the medal of St. Rose of Lima, the patron saint against vanity.
** The author gives many of these to the manga's characterization and general premise.
* {{Teacher Student Romance}}: [[spoiler: ''Something'' is implied to be going on between Logan and Jean-Paul, and maybe Paige Guthrie, Logan's teaching assistant, and Jean-Paul.]]
* {{This Is Unforgivable}}: Anna thinks she may have judged the Hellfire Club too soon at one point, but then she overhears them declare Quinn Fabray the best character on {{Glee}} and decides that she's right: they are jackasses.
* {{Too Dumb To Live}}: Anna and her friends entering a war zone basically for kicks, without a proper communications system.
* {{Uncanny Valley}}: [[InvokedTrope Invoked in the story itself]]. When Anna gazes at Jean-Paul for an extended amount of time, she notices that his face looks so perfect it becomes creepy.
