Not all fanfictional villains need to be on Know Your Meme. For example, the Black Hiver isn't on the site, but he's from a famous YouTube Poop. Fanfictional characters need to be at least actual and popular in order to be on here. Know Your Meme is just an example for fanfictional villains, not the main source.
I was the one who said no Robots but since the category and started to remove them once I found the category couldn't mske it without the Robot I have decided they count till enough of the animal villains are able to make it stand on its own.
