a place where all the cringiest people can be found/hell

Mainly a disgusting and corrupt place.

the cringiest fucking thing to ever exist
pros: sometimes has good theories about the storylines and endings
cons: cringey, likes to ship a probably 10 year old kid with an adult skeleton man thing across alternate universes, some alternative fan made universes are cursed and came from the 9th circle of hell
this fandom i dont reccomend joining

The undertale fandom has two sides. It is either the worst fandom on earth or filled with some of the most talented people out there.
The bad side enjoys shipping children with skeleton monsters, shipping long dead children with that skeleton monster's brother even though they have never met and creating AUs for the sole purpose of s*xualising the characters, including the children
The good side has some really good animators, cosplayers and artists. People on this side of the fandom like talking about undertale and playing the game, and are also usually embarrassed and disgusted by the shipping side of the fandom. This side can include theorists who talk about who gaster is, sans's backstory and the True Lab among other things.

The Undertale fandom is a diverse place, there's comics,animations, memes, remixes and fanart
A lot of brainlets assume that the entire fanbase is cringy, just because of the loud minority, that, A. get off the lewd images of skeletons, goats, fish, etc. , B. ship themselves with Sans (why Sans would never want to be with any of the fangirls, he'd definitely be filing restraining orders left right and center), C. unleash their annoying fanboy rants, with vulgar language, if someone dares say any slightest bit of criticism. I'm sure there's probably more examples, but I'm way too lazy to list any more...
Btw there's a majority of the Undertale fandom (or any fandom, for that matter) that aren't cringy, and just wanna show there amazing fanart, music, comics, whatever!
So the lesson is don't judge things to harshly. (I think that's what the lesson is, eh, whatever...)

Thank you for coming to my TED talk.

Pure cancer.

Undertale Fandom Syndrome(UFS), is a horrible disease that is founded in major fandoms. First discovered in 2014, it was created in its first stage with the FNAF fandom. It horribly spread when undertale became popular. Common symptoms include: comic dubs, weird fetish art, and annoying obnoxious children/preteens. Unfortunately, UFS has became a parasite that is sent to feed off hosts and cannot be treated or cured. The following fandoms that suffered the same fate include but not excluded: FNAF, Undertale, Cuphead, Bendy and the Ink Machine, Hazbin Hotel, and recently, Friday Night Funkin'.
