Need info on a fandom? You'll find it here. Are in a fandom? PM me to join the list. Not in a fandom? LIAR! everyone has a fandom. This is the 21st century.

This will come in sub categories. Live Action, Animated, Disney, Anime, and Games. The fandoms with be in alphabetic order in each category and yes, Disney has it's own category and to save time all movie with the avengers are under "Avengers" and all DC superhero movies under Justice League. Feel completely free to add fandoms to the list. These are just the ones that I instantly thought of and yes, most are TV series, but books, manga, and movies are allowed on the list too. Books will be placed in Live Action.
