[[caption-width-right:250:Sollux and Terezi. TheyFightCrime.]]

An AlternateUniverse branching off of Andrew Hussie's ''Webcomic/{{Homestuck}}''. As the title suggests, it uses Hussie's characters and mythos to create a police vs. criminals setting. HilarityEnsues.

There is little consistency in [[{{Fanon}} canon]], with the same troll having portrayed as a [[HomelessHero beggar]], a [[ReluctantMadScientist biologist]], and a [[SympatheticCriminal petty criminal]] in separate works. Usually, the stories take place in Alternia City, a metropolis with sizable Troll, Human, Consort, and Carapace populations. Usually, the Homestuck canon's {{Woobie}} is a [[TheChessmaster criminal mastermind]] with a copy of the EvilOverlordList, Vriska is a DirtyCop, and Rose is in charge of her very own Wiki/SCPFoundation pastiche. There are, however, two very different and distinct "mainstream" canons: the RP canon on DeviantArt and the general fanfic canon on the forums.

This AU also generates a slew of FanArt, much of which is indexed on the thread's first page.

Can be found [[http://www.mspaforums.com/showthread.php?34044-TROLL!COPS-The-AU here]], with a newer thread [[http://mspaforums.com/showthread.php?49930-TROLLCOPS-2-0-THE-REVENGENING here]], where it has inspired a currently running radio show that is planned to last for several years, using stories collected from both the old and new threads. The deviantART RP is [[http://trollcopsau-rpda.deviantart.com/ here]]. A Tumblr for the deviantArt RP is available [[http://askthetrollcops.tumblr.com/ here]].

----
!!''Troll Cops'' provides examples of:

* AncientArtifact: The city is chock-full of Skaian artifacts, many of which are suddenly in working condition after the Green Sun incident.
* AwesomenessByAnalysis: Gamzee, when he's sober. He was able to take down ''five'' of the Felt by himself.
* UsefulNotes/BritishCoppers: The ''Troll Cops: UK'' canon.
* CowboyCop: Terezi.
* DaChief: Typically AR, although in a few canons this role is filled by Equius.
* DeceasedParentsAreTheBest: Just about everyone's, depending on the canon you use.
* DisabilitySuperpower: Terezi, as in the canon (she's [[BlindSeer blind]] but can smell and taste light)
** Subverted with Mr. Pupa, who simply has [[ArtificialLimbs bionic legs]] for whenever he feels like walking.
* DivergentCharacterEvolution: Don Strider quickly begins developing a different personality from Dave. Don is much more open with his emotions, thinking that he can die at any time due to being a paradox clone.
* DemonicDummy: Cal, as in Homestuck. [[spoiler: But it turns out he was a hallucination.]]
* FiveManBand: The cops are this, although the order shuffles over time.
** Right after Sollux and Aradia join the force, we have:
*** TheLeader: Terezi Pyrope, the veteran who loves justice above all else
*** TheLancer: Vriska Serket, a darker and [[DirtyCop less scrupulous]] {{Foil}} for her partner Terezi
*** TheBigGuy: [[SuperStrength Equius Zahhak]], obviously
*** TheSmartGuy: Sollux Captor, a psiioniic with a knack for computers
*** TheChick: Aradia Megido, the idealistic new girl
*** ReasonableAuthorityFigure: Commissioner AR and Mayor WV. [[TheDitz Ditzy,]] yes, but never unreasonable
** After Aradia's death and resurrection as Aradiabot
*** TheLeader: Still Terezi
*** TheLancer: Terezi's new partner Sollux
*** TheBigGuy: This will always be Equius
*** TheSmartGuy[=/=]TokenEvilTeammate: The [[MissionControl dispatch officer]], Vriska, in all her [[DirtyCop corrupt]], [[ManipulativeBastard manipul8ive]] glory
*** TheChick: Still Aradia, because nothing else really fits
*** ReasonableAuthorityFigure: AR and WV.
** Over time, Aradia and Vriska switch roles as Vriska undergoes {{Chickification}} after [[spoiler:John helps her overcome Pupa's influence.]]
* {{Foil}}: Terezi and Mr. Pupa (both handicapped, neither handicapped by their handicaps, both chessmasters).
** Also Egbertman and Crowbro. One, a happy-go-lucky, LighterAndSofter hero who [[ThouShaltNotKill refuses to kill]] and flies around helping people during the daytime. The other, a hardened vigilante who operates at night and will not hesitate to murder criminals in cold blood.
* GoodCopBadCop: Sollux, being bipolar, manages to play both.
* HelpfulHallucination: Gamzee in ''[[http://www.mspaforums.com/showthread.php?34044-TROLL!COPS-The-AU&p=5044379&viewfull=1#post5044379 Sopor Somnolence]]''.
* KilledOffForReal: [[spoiler: Bro]]
* MagpiesAsPortents: Maggie's vigilante identity is the Magpie.
* NoodleIncident: That one time that Maggie [[spoiler:babysat for Portia.]]
* OriginalCharacter: Several. Prominent ones include the Magpie, Mama Captor, [[spoiler:[[DeathByOriginStory John's mother]], and Portia Nitram]]. Some stories focus pretty much exclusively on groups of {{Original Character}}s.
* ThePlan: Pretty much everything Mr. Pupa does.
* RagtagBunchOfMisfits: The Karkitty gang consists of three orphaned trolls. One has anger issues and a powerful BigBrotherInstinct, one is [[KindHeartedCatLover obsessed with cats,]] and one is a perpetually [[TheStoner stoned]] clown who was born into one of the richest families in Alternia City [[spoiler:before they were all murdered before his eyes by a [[OurVampiresAreDifferent rainbow drinker.]]]] It doesn't really get much more ragtag than that.
* ReasonableAuthorityFigure: Mayor WV, [[TheDitz ditziness]] notwithstanding. AR, too, whenever he's [[DaChief the commissioner.]] Additionally, Terezi and Equius are often portrayed as outranking the other cops, and they may also fill this role... DependingOnTheWriter, of course.
* RetCon: Many things, after being introduced in Homestuck, make their way into Troll Cops retroactively. Notable examples are [[spoiler: Kanpire, Mr. Pupa raising an alive version of Aradia, and Eridan's wand.]]
* SadisticChoice: In ''[[http://www.mspaforums.com/showthread.php?34044-TROLL!COPS-The-AU&p=5257107&viewfull=1#post5257107 Blind Girl Bluff]]'', Pupa forces Karkat to choose between kidnapping (and, if necessary, killing) his childhood friend Terezi or losing his gang. It's Mr. Pupa, so [[TakeAThirdOption taking a third option]] will probably not be helpful.
* ShameIfSomethingHappened: Pupa employs this on Magpie in ''[[http://www.mspaforums.com/showthread.php?34044-TROLL!COPS-The-AU&p=4480762&viewfull=1#post4480762 Silken Net]]''.
* ShapeShifting: Nepeta can turn into a car.
* StreetUrchin: In at least two canons, Karkat, Gamzee and Nepeta were three orphans who turned to crime in order to feed themselves.
* UnholyMatrimony: Pupa and Vriska, [[spoiler:[[MoreThanMindControl the latter unwillingly.]] When Aradia wakes up from her ConvenientComa, she takes her place by Pupa's side...willingly, this time.]]
* VigilanteMan: Bro. [[spoiler: [[KilledOffForReal It doesn't go so well for him.]]]]
* WrongGenreSavvy: Hussie, oh so much. As Alternia City's resident [[CloudCuckoolander crazy]] [[TheDrifter vagrant,]] he objects to the entire AU's existence and believes everything was meant to play out as it does in ''{{Homestuck}}.'' This frequently lands him in jail or the asylum, for his own safety.
