Fiction in Fiction

A universe for character who are fictional even within the bounds of the story. For example, some of these characters are part of a comic created by one of my characters, so they are doubly fictional. It's not really a universe, more like a place to lump them all together, but I've been referring to it as 'Universe (F)' for years and I'm not going to stop now. The F stands for Fictional.

As for the order, it's the following: Antie's comic characters, Annika's parody manga characters, mascot characters and tv show characters, videogame characters, then lastly OC's by my ocs.
