Tyler Durden is a fictional character in the book and movie Fight Club. The narrator is an employee specializing in recalls for an unnamed car company, he is extremely depressed and suffers from insomnia. The narrator in Fight Club is unnamed throughout the novel. Some readers call him "Joe" because of his constant use of the name in statements such as "I am Joe's boiling point". The quotes "I am Joe's [blank]" refer to the narrator's reading old Reader's Digest articles in which human organs write about themselves in the first person, with titles such as "I Am Joe's Liver". The film adaptation replaces "Joe" with "Jack", inspiring some fans to call the narrator "Jack". In the novel and film, he uses fake names in the support groups. In the film, Bob calls him "Cornelius" on the street after his testicular cancer support group name tag.
The narrator's alter-ego, Tyler is a charismatic, yet nihilistic anarcho-primitivist who despises consumer culture. He frequently describes and acts on his aversion to mass society, materialism, property, capitalism, and almost all technology and social order, going as far as vowing to annihilate civilization itself. Tyler's desired utopia is a neo-paleolithic paradise established in the post-apocalyptic ruins of industrial civilization.
"Because of his nature," Tyler works night jobs where he sabotages companies and harms clients. He also steals left-over drained human fat from liposuction clinics to supplement his income through soap making and create the ingredients for bomb manufacturing, which will be put to work later with his fight club. He is the co-founder of Fight Club, as it was his idea to instigate the fight that led to it. He later launches Project Mayhem, from which he and the members commit various attacks on consumerism. Tyler is blond, as by the narrator's comment "in his everything-blond way". The unhinged but magnetic Tyler becomes the antagonist of the novel later in the story.
