Fandomstuck (also called Fandombound) is a a rather chaotic Shared Universe hosted (mostly) on tumblr, which is based around personifications of various shows, books, and other fandoms.One of the most obvious parts of Fandomstuck is the large rp community based around it on tumblr. Other manifestations of it include games, comics and Homestuck style 'Fanadventures'. The term is also used to describe one-off art pieces about said personfications, and indeed this is where it all began; people took the concept and ran with it.By its very nature, incredibly meta.The list of players for the rp can be found here, the main collection of information and resources here, and the wiki Here. Also has a YMMV and characters page currently under construction.
Big Damn Heroes: Most of the superhero fandoms try, to varying degrees of success.
Depending on the Writer: A natural result of the lack of official canon. It's fairly common to find multiple takes on the same fandom, especially the more prominent ones. It's also variable as to whether or not the fandoms have any special abilities relating to their canon, or are strong, near-immortal humans, or are just Muggles.
Doing It for the Art: We repeat, a few pieces of concept art on tumblr led to an extremely active roleplay community, several stories and comics, a load of art, and three videogames; all of it non-profit and entirely because of the creators' devotion.
One of Us: It's basically built into the concept that it's made by massive fandom geeks.
The Other Darrin: A couple fandoms have multiple characters for the same series, and it has been mentioned that there are a lot more of them hanging out in the background. Word of God (or at least, listmod) states that multiple personifications for one fandom are perfectly normal in the fandomstuckverse. At least 12 different Homestucks have been spotted.
All There in the Manual: Due to the large cast and multiple writers, many concepts and bits of characterization only get expanded on in a couple of blog posts. Its also very common to find designs for fandoms that end up only as concept art. Fortunatley, there are a lot of archivists to make it easier to track.
Alternate Universe: Tends to be a lot of these, the most notable being the 'Humanstuck Intermission', which follows the lives of the fandoms if they were ordinary humans.
Canon Discontinuity: Canon, especially where it concerns the actual mechanics of the 'verse, such as what exactly the fandoms are or how they are 'born', is very inexact and most of the writers and rpers have their own headcanons, which may be pretty different from each other.
Magical Realism: Hints of it here and there; the whole humanoid personifications of fictional stories thing just seems to sort of happen, and there are ghosts and what at least appear to be various supernatural entities wandering around like it's no big deal.
Muggles: Normal people are occasionally seen interacting with the fandoms.
Mutually Fictional: It has been heavily implied that the fandoms and the writers/muns/etc exist in paralell universes of eachother, and that in at least some said universes, the muns are the fictional ones instead.
My Friends... and Zoidberg: As mentioned above, the basic premise is media personifications. There are a few personifications for other things around, but it make sense they might exist somewhere in the 'verse, such as the anons. There are also non-fandom AU counterparts of a few of the fandoms, such as Kayden the ghost. And then there's Tarn.
The Other Darrin: Eventually becomes an actual plot point with the introduction of alpha fandoms.
Broken Record: There's a puzzle in the Monster Lord's Castle in which there's an entire room of chests, and only three of them contain anything. The fake ones start fights, and every single one is followed by Homestuck saying "Fakes...great."
But Thou Must: The Monster Lord's Castle has switches to open the gates to the throne area. One of them has an option choice of "No" and "Fuck No", with both causing you to push it anyway.
Hammer Space: Attacking with weapons during combat is this, for the most part, due to how the battle system operates.
Improbable Power Discrepancy: For the most part, but painfully averted with the joke boss, the Sunny Fandom, which can be fought as early as finding Creepypasta Fandom, and even earlier in demo versions.
Magikarp Power: Word of God states that Yume Nikki becomes very dangerous once she obtains her ultimate weapon, which allows her to attack foes, due to having a wide variety of statuses to inflict on enemies and allies to allow her to adapt to most situations.
Shout-Out: A given, but notably, the Library in the Land of Love and Monsters has a different piece of dialogue for each tile on the map used by a bookcase. There's around 20 shout outs to literature, from Harry Potter to Nietzsche.
Slave Mooks: The Zombies in the Book are actually controlled by Chrome, a Necromancer. In addition, any Chimera enemy counts as this.
