What is Organization Xiii?
1.
A fictional group of fictional humanoid creatures known as 'Nobodies' within the video game of Kingdom Hearts. They are beings without hearts, and have banded together in an attempt to get their hearts back. Each wear a black trenchcoat with a hood, and have a signature weapon and element. Whether they are 'evil' or not is up for debate. They lack hearts, and thus are incapable of feeling any emotions such as remorse.
Also, they are probably the only 'villains' (for lack of a better term) in history to have a bigger fanbase than the main characters. They're names are all anograms of their original names with an 'x' added.
Organization XIII is awesome.
