''[[http://worldpeace.emilymarthasorensen.com To Prevent World Peace]]'' is a WebComic by Emily Martha Sorensen, who also made Webcomic/AMagicalRoommate.

InAWorld where {{Magical Girl}}s are commonplace, Kendra and her friends have fought against evil since grade school. However, one day her life takes a dramatic shift when Chronos, a natural born Mage with the power to see the future corners her outside of school. Chronos has been plagued with visions of a future where Magical Girls seek to control the world, [[WellIntentionedExtremist for its own good of course]], without anyone standing in their way, and Kendra is right in the center of it all. Kendra is quick to point out that it's [[IncorruptiblePurePureness impossible]] for a Magical Girl to turn evil.

"Except," Chronos is just as quick to reply, "for the times that they do."

Disturbed by these revelations, Kendra makes a heart-wrenching decision: She breaks off from her team, her friends and her family [[FaceHeelTurn to become a villain instead]]. But rather than JumpingOffTheSlipperySlope, Kendra's plan is (with the much reluctant help of Chronos) to hunt down Magical Girls at most risk of becoming corrupted, [[AntiVillain and either force them to change their ways...]] [[DarkShepherd Or else.]]

And that's the start. The comic focuses on one way a world with Magical Girls in it could develop, with a sprinkling of Worldbuilding and comedy to balance out the main plot.

!!Tropes in ''To Prevent World Peace'':

* AlliterativeName: Tiffany's M.O. with all her sentient magitek of death... that isn't about death.
-->'''Kendra:''' You can't leave me alone with that girl! She's crazy!\\
'''Tiffany:''' Hi, Stevie the Shower! Hi, Linus the Light Bulb! WHOA!! [[BreadMilkEggsSquick Robbie the Rocket Pack]]!\\
'''Chronos:''' Indeed, and you still haven't given me a convincing reason to stay.
* AmbiguousInnocence: Tiffany acts playful, childish and slightly spoiled. But she also commits crimes almost casually and cheerfully murdered a couple of villains who mistreated her.
* AntiVillain [[VillainProtagonist Protagonist]]: Kendra becomes this, to prevent a BadFuture where {{Magical Girl}}s control everything.
* AlwaysChaoticEvil: Played with. Born mages are believed to be evil, but [[WhiteSheep Chronos]] proves there can be good-natured mages as well. Their villainy seems to be more a matter of upbringing than anything else. Most born mages are in fact quite harmless. Their notoriety is mostly the result of several born mage crime families, who happen to possess the most powerful bloodlines.
* AlwaysLawfulGood: Played with. Magical girls are considered good by definition. Their magical system requires the user to be pure-hearted, but if a magical girl is strong-willed enough and/or sufficiently deluded she can keep her powers even after losing her innocence. For a time at least.
* AttendingYourOwnFuneral: Tiffany, does it, when invisible, as people think she died, as seen on [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html page 413]].
* BewareTheSuperman: The main issue with the Magical Girl Union. Sure, having all the world's superheroes band together and organize seems like a classic League of Superheroes... until you remember that said League is composed of 0-to-18-year old girls. Almost all of the Union's futures are bad as a result of having easily-manipulated and socially-inexperienced superheroes come together under one easily-controllable organization. Hence the title - To Prevent World Peace, So That Peace Isn't Defined As Killing Almost Everyone With Heroic Methods.
* BrainwashedAndCrazy: Villains have means of brainwashing magical girls or their loved ones into joining them.
* TheCorrupter: Rhea ''loves'' luring magical girls to villainy.
* DarkShepherd: Kendra's methods of culling corruption from the world Magical Girl population can be rather cold. However, she takes absolutely no joy from it.
** BadFuture!Kendra as well, but a lot more heartless, [[WellIntentionedExtremist hence being a separate trope]].
* {{Deconstruction}}: The series as a whole is a "light" deconstruction of Magical Girl anime. In this setting, magical girls can only receive their powers if they have a "purity of being" so that they completely believe in and represent an ideal, thereby gaining magical power that is used to hunt down the magical predators that plague society. Unfortunately, the forces of good [[WeAreStrugglingTogether are not one big happy family]]; [[MagnificentBastard politicians, businessmen, and even some muggles]] [[WouldHurtAChild manipulate their children into doing dangerous / socially unacceptable things]] for profit; and some of the "pure-hearted" heroes of justice kill people, and are never socially reprimanded for thinking that killing is a pure and honest thing (even in the case of justifiable homicide). This usually results in a lot of nice, kindhearted heroes having serious overconfidence in their ability to be incorruptible or infallible, and are extremely racist towards other types of mages as a result of their conflict and murder of said mages (most of the mages they fight are evil, but only because they're the minority that are stupid enough to cause havoc and fight out in the open), as seen by Kendra in chapter 1 when she is very close-minded to a sensible and peaceful oracle's warnings. A lot of the plot comes from the fact that most of the magical girls in the world think that the world is screwed up and they received their powers by being pure of heart, and by that [[InsaneTrollLogic logic]] they are the most fit [[DudeWheresMyRespect to protect / rule the world]].
* TheDogBitesBack: Tiffany has murdered two of her bosses via sabotage; one for being constantly abusive, the other for outright threatening to kill her if she didn't start making lethal weapons. This has its price, as she lost her magical girl transformation and nobody short of Kronos would be willing to tolerate her.
* TheEvilsOfFreeWill: The Union-controlled BadFuture Kendra seeks to avert.
* ExactWords: How Tiffany words things is very important, because they describe exactly what happened, and nothing else. Any implications are just that, implications. From the commentary for [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html page 413]]]]:
--> [[spoiler:"Tiffany once [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html described her funeral]] to Chronos as, "I saw my funeral years ago. No one even cried at it."]]
--> [[spoiler:[[ExactWords This is true]], but what little Tiffany didn't realize was that that didn't mean nobody was sad]].]]
* ExoticEntree: The Deathwave crime family has a shop that sells pets, minions, and exotic food animals. When one of the animals annoys Rhea by chewing her dress, she retaliates by ordering it for dinner.
* FaceHeelTurn: Right in the first chapter no less!
* FantasticRacism: Born mages are treated with suspicion, no matter how harmless and useless their powers are. They tend to have trouble getting jobs and lose them when their magic is discovered.
* {{Foreshadowing}}: Whenever Emily worldbuilds in the commentary, keep a lookout. Sometimes she hints at something that will involve that bit of info in the next chapter.
** For example, the first mention of Counterpoint: http://worldpeace.emilymarthasorensen.com/worldpeace189.html
* GrowingUpSucks: In most parts of the world magical girls are expected to give up their powers as they reach adulthood. The WordOfGod confims this is bound to change eventually, since magical girls are becoming more and more aware of their power.
* GenderRestrictedAbility: Only women can become magical girls. Adverted with born mages, who can be both female and male.
* HeroicNeutral: Chronos would really prefer to live life as a hermit. But since her visions of bad futures plague her sleep with nightmares, and some of these bad futures threaten the entire world, she has agreed to work with Kendra to avert them.
* HeroicWillpower: If magical girl is strong-willed enough she can keep her powers even well past losing her innocence.
* InnocentInaccurate: Tiffany, because she states what she sees, without knowing precisely what's happening due to her young age:
--> [[spoiler:"Tiffany once [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html described her funeral]] to Chronos as, "I saw my funeral years ago. No one even cried at it."]]
--> [[spoiler:[[ExactWords This is true]], but what little Tiffany didn't realize was that that didn't mean nobody was sad]].
* MagicalGirl: Well... ''Duh.''
* {{Magitek}}: Tiffany's inventions - according to WordOfGod, they are not scientifically sound, and it's only her magic that allows them to work.
* MoodRingEyes: In [[http://worldpeace.emilymarthasorensen.com/worldpeace315.html Chapter Twelve: Commentary]] one of the listed possible born mage powers is:
--> eyes that change color depending on mood
* OhCrap: One from Kendra and Chronos when they realize that [[spoiler:The Union (which is WellIntentionedExtremist personified for magical girls) has begun construction. But the architect isn't Kendra. IT'S HER BEST FRIEND.]]
* NeverFoundTheBody: Given how Magical Girl Forms are a kind of extra life, this is important. [[spoiler:From the commentary for [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html page 413]]]] "The girl in the fourth panel is one of the other girls in the group." And that girl is thinking]]:
--> [[spoiler:"Why does everyone think she's dead? There was no body. Doesn't that mean she's not dead?"]]
* NotSoHarmlessVillain: [[spoiler:Rhea may seem unimportant in the grand scheme of things, but she is colossally malevolent and quite good at [[TheCorrupter what she does]].]]
** [[spoiler:She even succeeds at killing her asshole RANGED-Touch-Of-Death Great-Uncle by buying off his ninja security. Of course, the fact that he was such a paranoid, trigger-happy boss helped.]]
* ParentalNeglect: The reason Tiffany's so messed up:
** Her irresponsible mother got pregnant out of highschool and died in a car crash. Her father left her mother upon realizing she was pregnant.
** Her Aunt never wanted children, only took care of Tiffany out of begrudging duty, and wasn't sad when Tiffany was believed to have died. [[spoiler:Or atleast, Tiffany ''thinks'' that her aunt wasn't sad. In the commentary for [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html page 413]]]]:
--> [[spoiler:"Tiffany once described [[http://worldpeace.emilymarthasorensen.com/worldpeace413.html her funeral]] to Chronos as, "I saw my funeral years ago. No one even cried at it."]]
--> [[spoiler:[[ExactWords This is true, but what little Tiffany didn't realize was that that didn't mean nobody was sad]]. It just meant that a) they didn't know her well, and b) even some of the ones who had known her slightly better than others felt more confusion than anything."]]
** The first father figure to actually care for her was a born mage who ended up becoming a criminal in an impulsive act of revenge. And while they shared three happy years together, they ended up encouraging one another to go deeper and deeper into villainy. The villains who interacted with her after he died ranged from neglectful to downright abusive.
* PubertySuperpower: Inverted. Magical girls gain their powers as young children and are expected to lose them during or shortly after puberty.
* PureIsNotGood: How some magical girls are not good, even if they are pure-hearted.
* PurityPersonified: You have to be this to be a magical girl in this universe. Although, the multiple kinds of purity that can be personified allows the creation of 'corrupt' magical girls.
* ScheduleSlip: Largely averted so far. The author is in fact two chapters ahead of what is posted online, and is posting it page-by-page every Friday. But, now, as of 2017-04-14, it updates on the first Friday of every month, but every month it makes $100, it will update every week.
* ShoutOut: The commentary for Chapter Five never so much as touched on it, but the situation with the Australian Magical Girl sounds somewhat reminiscent of [[Anime/PuellaMagiMadokaMagica Kyuubey]].
* TeenagePregnancy: From [[http://worldpeace.emilymarthasorensen.com/worldpeace416.html Page 416: Tiffany's Beginning: Commentary]]. Anything after this quote is a spoiler:
--> Tiffany's mother got pregnant in high school,
* UnequalRites: Magical girls are believed to be always pure-hearted and good, born mages are seen as villains. Other magic users consider magical girls' system to be “cheating”, mostly because it lets them survive as depowered humans, when their transformed form is killed.
* WhiteSheep: Chronos.
** Chronos has an outward persona as a True Neutral slacker, saving the world so that she can stop having traumatizing nightmares, and funding the protagonist by stealing millions through stock marketing and psionic powers. Whether or not she's good, evil, or really neutral has yet to be seen in the comic.
* WellIntentionedExtremist:
** At the start of the series, this is Kendra's most potential future as the leader of the Magical Girl Union. And the Union itself. She's genre savvy enough to quit while she's still sane and resolves to prevent other magical girls from falling into corruption. But she is willing to resort to unpleasant means to do so, such as destroying their magical girl forms and otherwise breaking the law.
** [[spoiler:Sadly, her best friend, Florence, takes up the mantle. And doesn't quit after seeing Chrono's warnings. And while Florence herself is a ReasonableAuthorityFigure, there are several potential bad futures in which other magical girls still end up using the union to cause trouble.]]
** One magical girl, Counterpoint, seeks to [[spoiler:end apartheid... by fomenting violent revolution with MassHypnosis]]. And since Kendra agrees with the goal, she initially decides not to do anything about the means by which Counterpoint intends to accomplish this.
* WordOfGod: After each chapter, Emily posts a page of commentary on the preceding, as well as the occasional bit of world-building on how her magical system works.
* WouldHurtAChild: Most of the villains. Sadly, this creates a setting where all magical girls and their fans assume that any mage who isn't a magical girl is evil incarnate. This nearly causes the protagonist to fight, or even kill, an oracle trying [[BreakThemByTalking by warn her about a bad future]] [[HeroicNeutral so she can go back to bed]].
** After becoming a villain, Kendra fights a lot of magical girls. Not to kill them (not permanently, at least), but to teach them of how stuck-up and close-minded they are. Since magical girl forms act as an extra life (with an expiration date), killing heroines in magical girl form is considered more ethical than stealing millions of dollars. This actually works great, especially against some REALLY deluded heroes (such as the Robin Hood fanatic who almost caused an international incident, and the Luck Stealer who was strong-armed by her father into cheating in Las Vegas).
* YesMan: Maria Athemyst is literally incapable of defying her socially abusive, misery-profiting dad.
-->'''Maria:''' This is ALL YOUR FAULT! I don't have a choice, my daddy is threatening to hire me out to other gamblers!\\
'''Kendra:''' You REALLY need to work on your no-saying skills.
