A character is a thing that is typically anthropomorphized by a creator who wishes to involve them in a story or series of stories and plans to have them be used to communicate a piece of fiction (or nonfiction in some cases) to an audience of some kind.  A character is crucial to any story whatsoever, and is almost always required when elaborating upon or explaining fiction.

This wiki has lots of characters on it, but I recommend you click on these links instead that talk about Major, Minor and Outer characters, as well as the Teams they belong to.
