Dune
The son of Duke Leto Atreides I and the Lady Jessica, Paul Atreides is the heir of House Atreides, a nuclear-armed aristocratic family that rules the planet Caladan. Jessica is a Bene Gesserit and an important key in the Bene Gesserit breeding program. According to the breeding program, she was to produce a daughter, who would marry Feyd-Rautha, a nephew of Baron Vladimir Harkonnen. However, Jessica falls in love with Leto and grants him a son. Although Paul is a boy, he receives a Bene Gesserit training, giving him among other things, great control over his metabolism, heightened senses, and knowledge of martial arts. He is also trained in weapon use by Gurney Halleck and Duncan Idaho, and receives training as a Mentat from Thufir Hawat.
In Dune (1965), Paul is fifteen years old; the Padishah Emperor Shaddam Corrino IV orders the family to leave Caladan and govern the desert planet Arrakis (known as Dune), though Paul's father Duke Leto is in full knowledge that the Emperor is colluding with House Harkonnen to destroy the Atreides as a perceived threat to the throne. On Dune, the family is betrayed by their Suk doctor, Wellington Yueh. He disables the House defensive shields, allowing the Imperial Sardaukar troops, dressed in Harkonnen uniforms, to capture Duke Leto and Hawat and to kill most of the Atreides army. Duncan sacrifices himself while attempting to hold off the Sardaukar and ensures Paul's escape. His betrayal motivated by the Baron's capture and torture of his Bene Gesserit wife, Yueh implants a poisonous gas capsule concealed within a false tooth on Duke Leto after his capture and instructs Leto to use it to kill the Baron. Shortly afterward, the Baron has Yueh murdered. Upon meeting Baron Harkonnen and his twisted Mentat Piter De Vries, Leto bites down on the capsule. He succeeds in killing De Vries — and himself — but not the Baron. Fed a poison for which only the Baron has the antidote, Hawat is forced to serve as the new Harkonnen Mentat. With some help from Yueh, Paul and Jessica escape into the desert.
They flee to the Fremen, who see in Paul the Lisan al-Gaib or "the Voice from the Outer World", a prophet they call the Mahdi whom they believe is "The One Who Will Lead Us to Paradise". Paul and Jessica take shelter in Sietch Tabr, a Fremen settlement led by the Naib, Stilgar. Paul and his mother train the Fremen in weapon use and martial arts, creating a formidable army. When Paul is accepted into the Fremen tribe, he is given the secret "sietch name" Usul, the Fremen word meaning "the base of the pillar." He chooses "Paul Muad'Dib" as his chosen name of manhood, to be used openly. Muad'Dib is the name of the adapted kangaroo mouse of Arrakis, and Stilgar relates that Paul's choice pleases the Fremen:
Muad'Dib is wise in the ways of the desert. Muad'Dib creates his own water. Muad'Dib hides from the sun and travels in the cool night. Muad'Dib is fruitful and multiplies over the land. Muad'Dib we call 'instructor-of-boys.' That is a powerful base on which to build your life, Paul Muad'Dib, who is Usul among us.
Paul leads a Fremen campaign of resistance against Harkonnen rule. He and Chani, daughter of Liet Kynes, take each other as mates and produce a son, named Leto in honor of Paul's father. Paul also reunites with Gurney Halleck, who had sought refuge with smugglers after the Harkonnen attack. In a bid to unlock his latent powers, Paul undergoes the process of spice agony via the consumption of the Water of Life. He survives, although barely, and the ordeal gives him knowledge of his male and female ancestors; this proves Paul is the Kwisatz Haderach.
Awakening, Paul launches an attack on the Harkonnen and Imperial troops with his Fremen army (and with his personal bodyguard, the Fedaykin), riding the enormous sandworms indigenous to the planet. In the attack, he learns that his son Leto has been killed in a Sardaukar raid. They win and Paul requests an audience with Shaddam IV. He threatens to destroy the spice melange, thus making transport between the planets impossible and effectively destroying civilization. In return for preserving the spice, he requires the hand of the Emperor's daughter, the Bene Gesserit-trained Princess Irulan as well as the Emperor's abdication in favor of Paul. Urged by the Spacing Guild, Shaddam accepts his terms.
