Hmmm. I've created a few OCs for "It's Already Here"(Hans and Anna's children) and the plan is to have them survive, so they could theoretically reappear in future stories set in the the same universe. But I wouldn't write a story focusing on them without having built up a lot of fannish goodwill towards them in particular and my writing in general.

Here's an explanation of her OC: [link]

OC kidlets make total sense. OC friends feel--it's not quite Mary Sue, but still.

I wished AO3 allowed two more things--author notes, so I know who to stay away from, and messaging.

I make up minor ones, waiters and bookstore clerks and whatever and try to make them a little interesting, but I do figure that people don't read fanfiction to read me(at least, not yet)

Oh! I just realized I've seen a bunch of Teen Wolf fics (across multiple authors, no less) where Stiles has the same twin brother. I've never actually read any of them, because I could hear Dick Tufeld's voice yelling "DANGER, WILL ROBINSON! DANGER!" in my head as I looked over the tags.

I like Scifigrl47s OCs, but generally speaking I rarely find OCs add much to the narrative.

chrismg, your OCs in "It's Already Here" are working very well. They ARE actually important to the story, as it is crafted. So there is little danger of them being silly and intrusive Mary Sues/Marty Stus. I must say I am so taken with the way you write Regina, especially, that she may well be overshadowing how I perceive any OC. But if you craft them as carefully as you keep Regina in character, then I will welcome them any time, in any story you care to put them in. Whereas that OC description that ita just gave the link to... total author self-insertion.

I actually was thinking of scifigrl47's OCs and how I had to skip their stories in Phil Coulson's case files, because while not Mary Sues, I just don't give a bleep about them, and I adore her writing and don't mind the OC characters when they're salt and pepper, and not the steak.

ita I can see where seeing that character over and over again would be annoying. It doesn't sound like she's using the charater to further the plot, she just really really realy really likes him and he seems to be her main fannish focus. It's not really about plot development or will he work well in whatever story, it's that Jet is her main fannish focus and so he's in everything she writes.

It seems kind of like bringing your beautiful cake to a chili cook off. Cake is great but people are there for the chili not for the cake.

But there are pro authors that tend to lean towards the same type of charater or character traits. When I was reading a lot of Dean Koontz he seemed to have a lot of kid characters that either acted older than their age or picked up things before hte adults did. When I was reading romance novels there was one writer who always wrote about how delicate and small her female protagnists were compared to the love interest and invariable the comparision was that the woman could barely finish half a sandwich without becoming really full and the guy would eat 2 sandwiches. And the woman would marvel about how strong and manly he was and so different from her in so many ways.

I like Scifigrl47s OCs, but generally speaking I rarely find OCs add much to the narrative.

Yeah, Scifigrl47's OCs are charming, but I haven't ran across any others that I like.
