Trout appears in several of Vonnegut's books, but the character is deliberately inconsistent as Vonnegut habitually changes major details about his life and circumstances with each appearance. Trout is consistently presented as a prolific but unappreciated science-fiction writer; other details, including his general appearance, demeanor and his dates of birth and death, vary widely from novel to novel. (Perhaps the most extreme instance of this occurs in
Jailbird, wherein "Kilgore Trout" is merely a
pseudonym of Dr. Robert Fender, a novelist and prison inmate.) Vonnegut makes no attempt to reconcile these sometimes extreme differences, and his novels do not form an internally consistent world. Trout performs a variety of roles in Vonnegut's works: he acts as a catalyst for the main characters in
Breakfast of Champions,
God Bless You, Mr. Rosewater, and
Slaughterhouse-Five, while in others, such as
Jailbird and
Timequake, Trout is an active character who is vital to the story. Trout is also described differently in several books; in
Breakfast of Champions, he has, by the end, become something of a father figure, while in other novels, he seems to be something like Vonnegut in the early part of his career. In
Hocus Pocus, Trout is not mentioned by name, but the protagonist is deeply affected while reading a Trout-like science fiction story. In early novels, Kilgore Trout lives in
Ilium, New York, a fictional town whose name is based on
Troy, New York (Illium was the Roman name for ancient Troy and Vonnegut lived and worked in nearby
Schenectady for some time). In later novels, Trout inhabits a
basement apartment in
Cohoes, an ailing mill community. While living in Cohoes, Trout works as an installer of "
aluminum combination
storm windows and screens." The ghost of Trout's son, Leon Trotsky Trout, is the narrator of the novel
Galápagos. Trout, who has supposedly written over 117
novels and over 2,000
short stories, is usually described as an unappreciated science fiction writer whose works are used only as filler material in pornographic magazines. However, he does have at least three fans:
Eliot Rosewater and
Billy Pilgrim—both Vonnegut characters—have a near-complete collection of Trout's work or have read most of his work; in
Galápagos, Leon Trotsky Trout goes on leave in
Thailand and meets an unnamed Swedish doctor who is a fan of Kilgore Trout. This doctor helps Leon desert the U.S. Marine Corps and defect to
Sweden, where he receives political asylum as a
conscientious objector to the Vietnam War. Vonnegut revised Trout's biography on several occasions. In
Breakfast of Champions, he is born in 1907 and dies in 1981. In
Timequake, he lives from 1917 to 2001. Both death dates are set in the future as of the time the novels were written. More recently, in an article for
In These Times Vonnegut "reports" that Kilgore Trout commits
suicide by drinking
Drāno. Trout "dies" at midnight on October 15, 2004, in Cohoes following his consultation with a
psychic, who informs him that
George W. Bush would once again win the
U. S. Presidential election by a vote of 5-to-4 in the
Supreme Court. The epitaph on his tombstone reads, "Life is no way to treat an animal." In
Breakfast of Champions, Kilgore Trout has part of his right ring finger bitten off by the book's other main character, Dwayne Hoover, when Kilgore attends an arts festival in the
Midwest. Trout also has an encounter with his creator, Mr. Vonnegut, in the final chapter. Vonnegut tells him that he is setting him free, in much the same way that
Leo Tolstoy freed his serfs, and that the rest of his life will be much happier: his work will be republished by reputable publishers, and his ideas will become very influential, leading to him winning the
Nobel Prize for medicine. However, Vonnegut cannot grant Trout's request to "make me young." In
Jailbird (1979), Kilgore Trout is revealed to be the only lifer in the Federal Minimum Security Adult Correctional Facility near Finletter Air Force Base, Georgia.
Jailbird, narrated by the fictional character Walter F. Starbuck, shows Kilgore Trout to be the only American convicted of
treason during the
Korean War. Kilgore Trout is the
pseudonym of (the equally fictional) Dr. Robert Fender, whose
doctorate is in
veterinary science. While in prison, Fender also writes many science fiction novels under another pseudonym, Frank X. Barlow, and works as the chief clerk in the supply room of the prison.
Galápagos is narrated by Leon Trotsky Trout (1946–1986), the son and only child of Kilgore Trout. Leon ran away at the age of 16, ashamed of his father, and never had any contact with him thereafter, until his death, when Kilgore appeared at the door of the "blue tunnel" that leads to the Afterlife. Kilgore appears at the door to the tunnel, urging his son to enter and proceed to the Afterlife. Three times Leon refuses, on the grounds that he wants to see more of human life in the hope of understanding it. During Kilgore's fourth appearance at the entrance to the blue tunnel, he threatens his son: if Leon doesn't leave the Earth immediately, the blue tunnel won't appear again for one million years. Since Kilgore has never lied to Leon, Leon knows this will come true. He is momentarily distracted by events on Earth, and the tunnel disappears.
Galápagos contains several flashback scenes that explain the breakup between Kilgore and his wife. Leon states that he became a US Marine because his father was one. Trout's appearance in
Galápagos is somewhat problematic for Vonnegut's continuity because the novel explicitly states that Kilgore dies before 1986, when the events of the novel take place. Yet
Timequake finds him alive more than ten years later. In
Galápagos, Leon uses his omniscient status as a ghost to confirm that he never fathered a child, so that Kilgore never had any descendants. In
Timequake, Kilgore's creed is "You were sick, but now you are well again. And there's work to be done." The novel also features Trout's last and presumably only poem: It is stated in
Timequake that Trout's father killed his mother when Trout was 12. This influences Trout later in life, when he is shown to say the phrase "ting-a-ling" whenever greeted or asked any questions. Trout accidentally becomes a great hero, rescuing many lives after the timequake, and finally receives a measure of acclaim: he spends his last days in a literary colony, honored for his heroism and some of his discarded works, which were preserved by a security guard. In
A Man Without a Country, Vonnegut receives a brief phone call on January 20, 2004, from Kilgore Trout in which they discuss George W. Bush's State of the Union Address and the imminent death of the Earth due to human carelessness. In
God Bless You, Dr. Kevorkian, Vonnegut's final interview is with Trout. == In other works ==
