[NOTE: With the release of Fight Club 2, much of the below information is now known to be inaccurate. This information will be updated once all ten issues of the sequel have been released and the entirety of the story is revealed.] Tyler Durden is The Narrator's split personality. He was created by the perfect storm of the Narrator's insomnia-induced insanity and his frustration with a hollow life of wage-slavery and consumerism. He is the manifestation of the completely free person the Narrator wishes he could be.
