Leto II Atreides () is a fictional character from the Dune universe created by Frank Herbert. Born at the end of Dune Messiah (1969), Leto is a central character in Children of Dune (1976) and is the title character of God Emperor of Dune (1981). The character is brought back as a ghola in the Brian Herbert/Kevin J. Anderson sequels which conclude the original series, Hunters of Dune (2006) and Sandworms of Dune (2007). Leto also appears as a child in the prequel The Winds of Dune (2009).
Leto is the son of Paul Atreides and his Fremen concubine Chani, and the twin brother of Ghanima. Leto is named for his paternal grandfather Duke Leto I Atreides, who is killed in the Harkonnen invasion of the desert planet Arrakis (Dune) during the events of Dune (1965). Leto II is the second child of Paul to bear that name, the first having been killed as an infant by the Emperor's Sardaukar in Dune.
Leto is portrayed by James McAvoy in the 2003 miniseries Frank Herbert's Children of Dune. The character will be played by Nakoa-Wolf Momoa in the upcoming Denis Villeneuve film Dune: Part Three.

Character biography
Dune Messiah
Chani dies giving birth to Leto and his twin sister Ghanima near the end of Dune Messiah. Blinded by the blast of a nuclear weapon called a stone burner, Paul is at a disadvantage when the Tleilaxu Face Dancer Scytale holds a knife over the newborns and threatens their death if Paul does not surrender his Empire to the Tleilaxu. Paul suddenly finds that he is able to see through the eyes of the infant Leto, allowing him to aim and throw a crysknife that kills Scytale.
Children of Dune
In Children of Dune, Leto and Ghanima are nine years old. Because of the melange ingested by their mother, which causes unusual effects for the Atreides bloodline, the twins are "pre-born", meaning that as fetuses they had been awakened to consciousness and to their genetic memories; they had been born as fully matured human beings in the bodies of infants. At the start of the novel, Leto is not prescient to the degree that his father Paul had been, but he senses the test his father had faced — to embrace a prescient vision of the universe is to set the universe on that path, a terrible responsibility that comes with terrible power. At the end of Dune Messiah, Paul had forsaken that responsibility by walking into the desert — his time as the Fremen messiah had shown him that he was not strong enough to be messiah/tyrant to the universe. Leto believes that he must face the same test.
At the same time, the Imperium created by Paul is ruled by his sister Alia Atreides as regent. The horror of the pre-born—the reason the Bene Gesserit call them "Abominations"—is that they are easily possessed by the ego-memories of their ancestors. When Bene Gesserit awaken to their "other memories" in the rite of the spice agony, they are adults with fully formed personalities, and can withstand the inner assault of their forebears; the pre-born have no such defense. Like Leto and Ghanima, Alia had been pre-born, and she succumbs to the pressure under an intense dose of spice. Among her ancestors is the Baron Vladimir Harkonnen, still hungry for revenge against his enemies, the Atreides. Alia is possessed by him, and unconsciously turns against the Atreides empire, plotting to kill Leto and Ghanima and to tear down the Imperium in a bloody civil war.
Independently, Leto and Ghanima both solve the problem of the pre-born. Leto constructs his own personality out of an executive committee of his ancestors; with all (the important ones) inhabiting him, none can possess him individually. Following an assassination attempt by House Corrino, Leto disappears into the desert leaving Ghanima behind. As part of Leto's plan, Ghanima hypnotizes herself to believe that Leto had been killed. The intense mental discipline needed for this self-deception builds a safe haven in Ghanima's mind for her own personality to safely develop, with the memory of Chani acting as a guardian.
Leto finds Jacurutu, a sietch that has been forbidden to anyone by Fremen law. There he faces the test his father had refused to take, and embraces prescience, its visions, its attendant power, and the terrible price it will extract — to follow his vision, Leto will become a symbiote with the sandworm, setting the universe on the Golden Path, a future in which humanity's survival is assured. After consuming massive amounts of spice, he allows many sandtrout to cover his body, the concentration of spice in his blood fooling the creatures:
God Emperor of Dune
A little more than 3,500 years have passed, and in God Emperor of Dune, Leto is now almost fully transformed into a sandworm. He is almost invulnerable to physical damage, his lone weakness being an intense vulnerability to water, shared by the sandworms themselves. "Leto's peace" has kept the universe quiet for that time, and the entirety of human society has become an audience for him. He is their emperor and their god. His all-female army of Fish Speakers keeps order and act as priestesses.
Arrakis is now a verdant planet with a great river named after Duncan Idaho. Except for Leto, the sandworms are extinct, and all that is left of the "ocean without water", bahr bela ma, is a desert preserve set aside for Leto alone. The old institutions, the Bene Gesserit, the Bene Tleilax, the Spacing Guild, the houses Major and Minor, the Landsraad, the technocrats of Ix, and CHOAM, have all faded from power in the face of Leto's hydraulic despotism: since he has absolute control of the spice on which the whole universe depends, he has the universe in the palm of his hand, and ruthlessly enforces his simplistic order.
Leto has taken over the Bene Gesserit's breeding program for himself, the same program that produced his father, the Kwisatz Haderach. His Golden Path is nearly assured now, and his long rule has begun to bore him; the trap of prescience is an existence without surprises. To ensure that humanity will survive, Leto has spent millennia enforcing quiescence on humanity: people rarely travel, rarely fight in wars, rarely do anything but live and worship him. This repression has created in humanity a deep and urgent need to explode upon the universe, scattering itself beyond the reach of any single tyrant. Leto seeks a solution in which he might die without destroying his people; if a god commits suicide, his worshippers would commit suicide with him. The only option is revolution, so Leto breeds for the person who will overthrow him: Siona Atreides, the daughter of his majordomo, Moneo.
Siona is the second human to carry a gene that makes her invisible to prescience and thus uncontainable by it, the first being the Count Fenring, from the novel Dune. Siona is different from Fenring in that she can pass on this gene to her descendants, whereas Fenring was a genetic eunuch. Since Siona cannot be seen in a vision, she cannot be controlled by a vision, nor can her descendants. Thus the tyranny of prescience will end with Siona — humanity can never again be bound by a powerful prescient like Muad'dib or the God Emperor himself.
Sequels
More than 1500 years after his death, Leto II is brought back as a ghola on board the no-ship Ithaca in Brian Herbert and Kevin J. Anderson's continuation of the original series, Hunters of Dune (2006). Even at a very young age, this Leto shows signs that he may be more than he seems. During an assassination attempt, he appears to transform into a small sandworm and defends himself before reverting to an innocent one-year-old. Genetically, he is noted to be very unusual; as he grows older, he displays an uncanny intelligence, but is very withdrawn. The current Duncan ghola notes that it had been cruel to bring Leto back without his twin sister, who had been so much of the original's life.
In the concluding novel Sandworms of Dune (2007), Leto (like Sheeana) can control the worms. After his memories are returned, he leads the seven sandworms being transported on the Ithaca to wreak havoc in Synchrony, homeworld of the thinking machines. At the conclusion of the battle, all seven worms fuse together into one massive worm; Leto steps inside, and they descend below the planet's surface. While it is stated that Leto had foreseen the conflict with Omnius and the thinking machines, the ultimate fate of the Golden Path, or the worms' status on Synchrony, is left open.
In adaptations
Leto is portrayed by James McAvoy in the 2003 miniseries Frank Herbert's Children of Dune. Laura Fries of Variety wrote, "the mini picks up a great deal of charisma when McAvoy and [Jessica] Brooks [as Ghanima] come aboard as the next generation of the house of Atreides." The characters Leto and Ghanima were aged from ten-year-olds to teens for the miniseries, which Emmet Asher-Perrin of Tor.com called "a smart move here, as finding two ten year old kids who had the ability to behave as though they had millennia of ancestral memory bubbling up inside of them was always going to be an impossibility." Asher-Perrin also called McAvoy "easily one of the highlights of the miniseries, and he plays the part with a sort of brooding-yet-impish etherealness. He's really excellent, and his rapport with Jessica Brooks's Ghanima is dazzling.
God Emperor of Dune is parodied in the animated television show The Grim Adventures of Billy & Mandy in the 2003–04 season episode "Mandy, the Merciless", with Mandy as the emperor Leto II, and Billy as Duncan Idaho.
In 2025, Nakoa-Wolf Momoa was cast as Leto in the Denis Villeneuve film Dune: Part Three.
