Writeups.org (est. 1999) has thousands of detailed fictional character profiles. Chiefly from #comics (principally #dccomics and #marvelcomics), but with a large selection of #videogames, pulp novels, movies, etc. characters.
It is primarily a #TTRPG site. But it is often used by #fanfic folks, comics fans, gamers, #cosplay makers, or just to look at the pictures.
