Billy Pilgrim is the main character in the novel Slaughterhouse Five. He served in Word War II and witnessed the bombing of Dresden as a prisoner of the Germans. Later in life, he became an optomitrist and married a woman named Valencia. He was almost killed along with his father-in-law in a plane crash, but managed to survive. His wife died while trying to visit him in the hospital. He had two children, a son and a daughter. His daughter (Barbara) was forced to care for him in his older life, while his son (Robert), who was at one point a deliquent, became a Green Beret during the Vietnam War. He was kidnapped by the Tralfamadorians, and brought to their homeworld where he was put into a zoo along with Montana Wildhack, a twenty-year-old pornographic fim actress. They are expected to mate, and eventually do. Billy returns to Earth to publicize and share what he has learned from his time on Tralfamadore, but is killed by a gunman hired by a man Billy knew from his army days after he gives a speech.
