Why are there so many "OCs" in the "Total Drama" fandom?

I added quotations to OCs because let's face it, how many are THAT original? Plus, there are a lot of Mary-Sues and Gary-Stus and that isn't a original...They're just...perfect and not original, which reminds me of "the phrase that pais" (This makes me shiver. jazmín Alice Canary Ramirez Tansho is the worst "OC" I have seen yet...so scary. *shudders*) and "Twilight," but I'm not getting into that. (Don't go, "twiglight [This is kind of a personal joke that I don't feel like getting into right now.] is da bestest ding EVAH!" please. That is really off-topic. I'm just saying.)

Like, I know that there are OCs in every fandom, but there seem to be so many más in the "Total Drama" fandom than any I have seen; I've even been into "Harry Potter," "Glee," and a few other popular fandoms, but none have even come close to the amount of OCs I have seen in the "Total Drama" fandom. I know that it is a popular mostrar after all, but the amount of OCs is just so overwhelming.

I realize that making OCs can help one become a better autor if they plan to write fiction instead of fanfiction--I've even made segundo generation characters before for this purpose, not that I have publicado the majority of that--but how many people are actually making OCs to become a better author? My guess is that not many are doing this for this reason.

Others, I'm guessing, just fantasize about being with a cartoon character so they make OCs to live out that dream. I've had "cartoon crushes" myself, but I haven't made OCs based upon myself to bring that dream closer to becoming real.

I'm sorry if I have offended anyone--I didn't type this all out for that purpose--but I'm just really curious about this. I'm also not saying that it's necessarily a bad thing--I have found some OCs that are likable--I'm just asking why there's such an amount.

Why are there so many "OCs" in the "Total Drama" fandom anyway?

P.S. Sorry for wasting your time with my long rant.
