>>109659It's been talked about to death, but I can do my best to summarize what I remember from previous threads:
>Overused visual designA majority of OCs feel cheap or rehashed from a purely visual perspective. Everyone's seen the umpteenth elf-demon-other high fantasy/nerd-introvert-gamer girl OC already and there's nothing a creator is gonna do that's going to set them apart in terms of attractiveness
>Poor/generic background that pales in accessibility to licensed character flexibilityOCs are often just a D&D sheet of stats, likes, and dislikes. Sometimes they're straight up nothing at all but a design. There's nothing that makes anything about the fetish situations they're in appealing. Licensed characters exist in a world and personality traits can be derived from it, and can subsequently be broken in fanfiction. Many artist/creator OCs simply don't do this for their OCs. It's hot that in someone's headcanon, the extremely fit and strong-willed Chun Li (well-defined character with voice lines and backstory) starts taking up cooking after SF3 and plumps up while developing a weakness for pastries. On the other hand, who cares that your nonspecific gamer girl is getting fat and lazy as a MMORPG player? There are a bunch of scenarios just like hers. Squarewave already created multiple one-shots and comics for an elf girl he's never revisited again, your Unique the Wood Elf is not going to beat anything he's done in terms of pure horny.
>Lack of any kind of developmentThe reason why people globally respond well with OCs like those belonging to BWS, Ohasi, DebuIsCool, woot, etc. is in part due to that there's some kind of investment put in by the author. The author likes the character to create a world or scenario for them in a tactful and interesting manner and the fat fetish scenarios just hit better. The character has relatively general appeal and fancoomers are able to create their own fetish headcanon or simply think the horny vision of the creator aligns with their own. This segways into...
>The creator doesn't really give a shit except in the heat of the moment and then views their OC as a status symbolAudiences can tell when a creator actually gives a shit about their OC and doesn't view them as just a fat fetish status chip (i.e., any of the artists who go "man i haven't drawn [my oc] in a while, huh... haha...."). Ohasi basically went from fat fetish on a side account to fat fetish on a main account because he just loved putting his girl into all sorts of relatable sexual teases and fantasies. I still follow what used to be his main just to see the work he puts into art training in terms of anatomy, scale, shading, etc.
>Someone else's inflexible, unrelatable, and extremely visible fantasyThere are plenty of autists with OCs that have nothing universally interesting about them but because they're commission whales who are viewed as reliable income, they become pronounced and known. It's someone else's highly specific and context-devoid fantasy and not one that people can generally relate to and imagine their own version of. Cool, your half-naked catgirl maids are getting tube fed. Again. At least Wonderbread Commissioner Guy is able to set aside enough money to have a bunch of artists fulfill his fantasy and then fuck off for a while.
I absolutely guarantee that I missed something, but I hope that provides some context.
