Now when I say OCs in fanfictions, I don't mean as in self-insert OCs or one of OCs for specific fanfictions. I'm talking as in reoccuring OCs, OCs that appears in multiple of different original fanfictions made by the same person. AnimationFan15 has Charlotte and Maddie, YoshiRocker13 and Andrew Brauer have Sophia, Maria, and Lee, TMNT1987Dude has Rodney, The Rolan Circus, etc., and I've even got a few of my own (Valerie, Clark, Tia, Mackenzie, etc.)

The reason why I bring this up is because when it comes to writing fanfictions, I'm always trying to make it feel as close to a Loud House episode as possible. However, with OCs, I feel like those are exclusive to the creator and not really from the show, so if an OC appears and you don't know who he/she is, chances are the reader is going to be left confused and it may not seem like a Loud House episode with inserted things that only the creator knows about. Plus, the reader will have to search back to when the OC was introduced to learn about them and that might seem a bit tedious, to have to go back to something to fully understand something else. It's I'm not saying OCs are a bad thing. Heck, I love some of my OCs, and others too, but this is just how I feel when it comes to OCs to the average viewer/reader.

So I want to know, what are your thoughts on the idea of reoccuring OCs in fanfictions?
