I kinda did the 'De-Oncelerization" in my time in the Undertale fandom to an OC I created.
Living for all the Benadryl cucumber names
It's...kinda weird how common it is for fans to ship certain characters with themselves. In Danny Phantom, people shipped Phantom (Danny's ghost half) with Fenton (his human half). In the Hazbin Hotel fandom, people ship human Alastor (before he died and went to Hell) with Radio Demon (his demon form). Neither were/are anywhere close to how things went down in the Onceler fandom, but I can't help but find the whole thing fascinating.

A part of me wants to cringe and call this weird and everything, but honestly if I didn't have her reading this stuff out loud, I'd probably be cool with this stuff... I was in this fandom for a hot minute... And sans undertale... and Bill Cipher... I can't criticize shit...

The first video of Sarah I ever watched, and there would be a lot of things to hate. - Presence of the mug - Absence of another mug to stop her gesturing with her other hand (apparently the reason for the first mug). - Overexaggerated facial expressions ... but I notice that I don't mind in the slightest. I was immediately drawn in by her personality alone. I couldn't stop watching the video, even if I tried. This is amazing. Keep it up.

I'd say Homestuck did come close to what you described, but it did actually have just an absurdly large cast of characters (albeit many are the same person over and over). But in terms of the contrived shipping choices, the ridiculously complex roleplay interactions, fan interpretations of existing characters, disregarding the text itself etc then it does hit pretty similar.

After you described "the hot boy redeemable villain thing" I understoond the "mystery" of teen girl fandom ten to get mainstream hate. I didn't meant it to sound as rude as it did but man that sounded cringy.

Honestly, ive read and shipped way worse in my lifetime so at this point im fine with classic oncest. Im so deep into fanfic that nothing phases me anymore and this seems perfectly normal honestly.

I feel like Sans is just a long, drawn-out Onceler phenomenon. Millions of AUs, selfcest, and ask blogs are all apparent, but unlike the Onceler it happened over the course of a year or some odd (idk, i didn’t keep track the whole time) rather than booming suddenly for a month before fading.

I'm surprised I haven't seen Varian from Tangled: the Series called the "new onceler" yet, because he's very popular with teens and spends a good chunk of the series being morally ambiguous. He's also the nonthreatening kind of "cute" that teenagers just figuring themselves out like. And he is full of A N G S T. He ticks a lot of the boxes, but honestly from what you're saying the onceler fandom was lightning in a bottle and we'll never see something quite like that again. I was pretty much too old to be into the onceler fandom, but it sounds absolutely bonkers!

Lorax 2012 writer #1: "Hey, do you think we're making this villain character a bit TOO attractive and likable?" Lorax 2012 writer #2: "Why is that a problem?" Writer #1: "Well, those types of characters tend to attract a... certain type of really weird fanbase." Writer #2: "What, you mean shippers? Don't worry, I've already planned for that. There's absolutely no other character in this movie, male or female, that could be turned into a viable love interest for this dude. I mean, who are they gonna ship him with? Himself?"

2:42 PEOPLE SAID THAT ABOUT KOMAEDA- NO PLEASE- HES SO MUCH MORE INTERESTING AND COMPLEX AAAAAUUGGHHH- (And no, Komaeda is not even close to the onceler. Thatd probably be Izuru, since people for some reason ship him with Hajime, which is the same character. Even though Komaeda is a perfectly good character to ship Izuru with, smh)

I liked the character’s ONE song and thought it was catchy. The fandom itself I find to be giga cringe. But that’s plenty of fandoms.

Seeing all the stuff that fanbase pulled, I can pretty confidently say that Sans is(/was) the new Onceler. -Teenage girls thirsting -AU versions who have nothing to do with the og (typically refered to as *insert one word to describe the character here*!sans) -Sanscest bs -How they are/were called "sans fangirls" not "undertale fangirls" -Completely missing the point of the original story because "Hehe funni skeleton with pp"

Neat video! To address something you said, I don't think people equating interest in a villain with endorsement of the same is on the rise with social media. I think its a result of shallow or non critical thoughts, which is sort of part of human nature generally and part of american culture specifically. And by american I mean western culture generally and this thread of anti-intellectualism we have.

Ok I know the onceler came first but I am deeply offended by the fact that people dare to compare sans undertale to him, if you think it's even close to the same I gotta say you're wrong because at least the onceler hype died down; to this day there hasn't been a single moment where I have been able to look up the tag of undertale in Any social media without being completely FLOODED with horny sans art. Not even nice skelebros content, literally at least half the tag is people who are horny for sans. And at least the onceler makes a tiny bit of sense! he's a skinny tall white blue eyed guy AND a redeemable villain, there's a lot of other prominent examples of people being into that, What the hell is the appeal for sans? He's a stinky skeleton who does nothing all day, doesn't shower and who's only interesting traits are nothing in comparison to the rest of the ut cast, the only appealing version of him is completly fanon and even then all the traits hes given are just taken from Alphys (Scientist, angst, bisexual/lgbt+, plays a big part in the plot, has a dark secret, theres probably more but im tired). He literally has nothing going for him and still. ugh sorry for using your comment section for venting I'm just mad because one of my fanart pieces i spent several hours on got completely obliterated from the ut tag by sans stuff and i don't really have a lot of places to talk about it... Edit: An important point i didn't cover, I can't believe im saying this, I was in the sans fandom. And for waaaaaaaaaaaaaaay longer than Sarah was in the onceler fandom too, I can't remember the exact time but if im recalling correctly at least a year. That's probably a big part of why I hate it so much, I've been on some the deepest end of this fandom and I know how bad it gets, so now that i have like,,,, critical thinking and better influences I just get very frustrated that this is still going on like damn, i was there because I literally didn't know better, just a literal child doing stupid shit, but the most famous people there are whole ass adults who did and do awful shit (Included but not limited to: Demonizing a traumatized child for being traumatized, drawing and writing inc*stuous porn, p*dophilia, fetishizing gay men, I could go on this is insane) it's just tiring honestly. Edit 2: Ok after watvhing the whole video I take it back, the onceler fandom IS weirder, I wouldn't say it's worse tho, the shitty shitty stuff that happened in this one mostly doesn't seem to be that prominent in the onceler fandom from what I'm seeing (except the inc*st stufortunately) but to tie it all in a joke: Sans fandom is The onceler fandom of it was less weird and more morally questionable and still alive

I was happy to see Raymond because as someone with heterochromia, I have never seen it as just a normal trait before. It's always some kind of mystical, dual heritage, demon posessed, Dear GOD stop with the Naruto references kinda thing. Raymond was just a character with two different eye colors. YES. As someone who only watched The Lorax this week, I'm glad I waited xD

I've been thinking over what exactly prevent certain characters from being Once-lers, because a lot of them fit the bill of everything you described 'a new Onceler' to be. My theory is that they're either surrounded by a cast of characters that interesting enough by themselves (Nagito and Sans), have a canon relationship (Zuko and Kovu) or have just too little of a personality that people judge them from looks alone and get conflicting ideas (Raymond). There's also the Joker, Bill Cypher followings, but that's another thing entirely.
