'''Heinoustuck''' is a ''Webcomic/{{Homestuck}}'' fan adventure by a user known as Yorsh. A very, ''very'' [[DarkFic dark]] ''Homestuck'' fan adventure.

It takes place in a world where kids have to go through a rite of passage known as "transmutation" when they turn thirteen, a process that [[BodyHorror mutates them horribly]], [[PainfulTransformation is implied to be painful]], [[ImmortalityImmorality renders people immortal]], takes four days to complete and, in some cases, [[NotHimself alters their personalities]]. John is, understandably, terrified of it happening to him and avoids his dad throughout the story to make sure it doesn't happen - but [[AllThereInTheManual the handy manual]] shows us that it's inevitable.

The comic started when its author decided to draw the Alpha Kids in a creepy manner on a whim and kept going from there. Eventually, she managed to mutate all of the kids, guardians and trolls and eventually made a fan adventure out of it.

Can be read [[http://mspfanventures.com/?s=1018 here]], but please [[NightmareFuel know what you're getting yourself into]]. Alas, it has been discontinued in 2014, but some information about the plot are still available whether they're archived or are still lurking in one of Yorsh's old blogs.

!!Tropes

* AbusiveParents: Dad, Mom and presumably Bro and Grandpa are... to put it mildly, a ''lot'' less nice than they are in canon. So far we've seen Dad toss a ''knife'' at John and Mom strangle Rose with her tentacles. Additionally, [[BigFriendlyDog Becquerel]] looks a lot more angry and feral than in canon.
* AdaptationalJerkass: Jade, due to her newfound omnipotence, is a MoodSwinger SpoiledBrat in this AU.
* AdaptationalVillainy: Many cases, due to the transmutations.
** Dad Egbert, a loving guardian in ''Homestuck'' canon, is much more violent towards John here.
** Mom Lalonde, similarly, is portrayed as aggressive and violent towards Rose, which clashes with her [[ParentsAsPeople flighty but well-meaning portrayal in canon]].
** Becquerel, a BigFriendlyDog in canon, is now a feral, aggressive HellHound.
* AllThereInTheManual: Yorsh provided a lot of info about the fan adventure (the designs of characters who haven't made their debut, the characters alternate personalities, etc.) on her blog. However, since she changed her blog (twice), this information is now really difficult to find.
* BirdPeople: Dave was horrifically mutated into one of these.
* BodyHorror: For reference, [[http://25.media.tumblr.com/tumblr_m7fl4sk59I1qkhx1bo1_1280.gif this picture]]. And that's just the Beta Kids, Alpha Kids and Trolls. There's more where that came from!
* CombatTentacles: Rose, her Mom and likely Feferi.
* DarkerAndEdgier[=/=]DarkFic
* DemBones: Aradia, who has a ram skull for a head.
* DemonicDummy: As if Lil' Cal couldn't get more terrifying, here he's ''fused with Bro Strider and later Dirk!'' Meaning that Bro is more-or-less turned into a ''supersized Lil' Cal''.
* EarAche: Becquerel's ears were chopped off and sewn onto Jade's head.
* EyeScream: Post-transmutation, John will have one of his eyes hanging out of its socket and coated in green slime. Equius, meanwhile, seems to have had his eyes gouged out entirely and Terezi's eyes appear to be ''on fire'', Sollux 1 and 2 have their original eyes gouged out, sewn shut and received a huge eye right inbetween.
* GiantEnemyCrab: Karkat.
* GlasgowGrin: Rose has one. [[AndIMustScream She can't frown because of it]].
* HellHound: What Becquerel has turned into.
* HumanoidAbomination: Rose, her Mom, Roxy, Jade and Feferi due to their respective transmutations involving something [[EldritchAbomination eldritch-y]].
* ImpaledWithExtremePrejudice: Dave (with a sword), Tavros (with a lance), Jane (with a double-ended trident) and Equius (with several arrows).
* LaughingMad: According to WordOfGod, Dirk is prone to randomly doing [[DemonicDummy Lil' Cal's]] evil laugh post-transmutation.
* LittleMissAlmighty: Jade.
* MonsterClown: Dad, post-transmutation. And boy howdy is it terrifying.
* MoodSwinger: Jade, due to her omnipotence messing with her brain a little.
* MultiArmedAndDangerous: Jade, Vriska, Rose and possibly Feferi.
* MultipleHeadCase: Sollux is bisected down the middle, has two heads and his halves are connected by his psiionics.
* {{Narcissist}}: Kanaya, according to WordOfGod.
* NotHimself: Played with. The transmutation alters all of their personalities, but out of the Beta Kids, only Rose has really changed. Dave, Jade and according to WordOfGod, John are actually more [[{{Flanderization}} flanderized]].
* NuclearMutant: Jade, due to having Bec's ears and tail forcibly stitched onto her body, has gained his powers and with it came a severe amount of radiation. She's also grown a bunch of arms.
* PlagueDoctor: Dave has what looks like a plague doctor mask sewn onto his face, completing his freakish man-bird look.
* RealityWarper: Jade and Bec. So far Jade has been shown to be capable of remotely turning on John's computer despite being ''miles away from him''.
* SpidersAreScary: Vriska has spider legs, fangs and eyes.
* StepfordSmiler: Nepeta and Feferi.
* WingedHumanoid: Dave, who has giant crow wings. Terezi and Kanaya too, having dragon and moth wings respectively.
* WithGreatPowerComesGreatInsanity: Jade. While "insanity" might not be the right word, WordOfGod states that Jade's newfound omnipotence has made her a bit of a spoiled brat.
