Tanidia He is the only character to feature in all six of Herbert's original Dune novels. Idaho was portrayed by Richard Jordan in David Lynch's 1984 film version of Dune, and by James Watson in the 2000 Sci Fi Channel miniseries. Edward Atterton assumed the role in the 2003 miniseries Children of Dune. The character is played by Jason Momoa in the 2021 Denis Villeneuve film Dune.

In Dune (1965), Duncan is described as a handsome man with "curling black hair" to whom women are easily attracted. Paul Atreides notes Duncan's "dark round face" and "feline movements, the swiftness of reflex that made him such a difficult weapons teacher to emulate." And in Dune Messiah (1969) he is described as having "high cheekbones" and "definite epicanthic folds." Lady Jessica calls him "the admirable fighting man whose abilities at guarding and surveillance are so esteemed." Duncan is fiercely loyal to House Atreides, a skilled pilot, and as a Swordmaster of the Ginaz is a gifted hand to hand fighter. In the fight that ends with his death in Dune, Duncan kills an unheard of 19 Sardaukar, the Padishah Emperor's fearsome supersoldiers. The Sardaukar sell his body to the Tleilaxu; subsequent gholas of Duncan possess the rebellious streak of the original. In 1976's Children of Dune, Lady Jessica tells Duncan that he was drawn to her daughter Alia because "you wanted a girl you saw as a younger version of me." In God Emperor of Dune (1981), the latest Duncan ghola discovers that one of his predecessors had fathered a child with a woman named Irti who closely resembles Jessica.

At the time of Frank Herbert's original novel Dune (1965), Idaho is a Swordmaster of the Ginaz in the service of House Atreides and one of Duke Leto's right hand men (with Gurney Halleck and Thufir Hawat). When the Atreides take over the planet Arrakis at the order of the Padishah Emperor Shaddam IV, Idaho becomes Leto's ambassador to the Fremen, the desert people of Dune that Leto hopes will ally with him in the coming war against the Emperor and the Harkonnens. Idaho goes to live with the Fremen, serving both Leto and Fremen leader Stilgar. When the Emperor's dreaded Sardaukar attack Arrakis in the guise of Harkonnen troops, Idaho initially survives the assault and saves Leto's son Paul Atreides and concubine Lady Jessica. When they are cornered at a Botanical Testing Station, Paul and Jessica flee while Idaho holds off the enemy, but he is ultimately killed. and made clear in Children of Dune (1976) that Idaho had killed an unheard of tally of nineteen Sardaukar before dying.</blockquote>

Although a third party work not connected to the main Dune series, but endorsed by Herbert in his lifetime, The Dune Encyclopedia provides some background on the characteristics, personalities, and often gruesome deaths of 17 additional Duncans from the time before the Duncan that is the focus of God Emperor of Dune, further noting that there were "well over seventy Duncans".

The Bene Gesserit become the consumers of Idaho gholas in Heretics of Dune (1984) and Chapterhouse Dune (1985). However, the gholas are repeatedly assassinated after several years, and the Sisterhood suspect the Tleilaxu. Not knowing exactly what purpose Idaho will serve, the Bene Gesserit believe that the Tleilaxu are using the gholas to control the timing of his release upon the universe, implying some Tleilaxu purpose in addition to their own. The current ghola survives such an attempt and Miles Teg is able to restore the memories of Duncan Idaho to the ghola, but Duncan can feel that the Tleilaxu planted something else in his mind. When Murbella, an Honored Matre, tries to sexually bond Idaho, he entraps and enslaves her, revealing the Tleilaxu purpose: To conquer the Honored Matres by using a better version of their own sexual techniques. When Murbella tries to bond Duncan, the Tleilaxu's plan comes to fruition, and he becomes aware of the memories of all the other Idaho gholas, though he is also imprinted to her. It is later determined that the Tleilaxu had mixed the cells from almost all of the Idaho gholas to make this one. Idaho and Murbella are confined to a no ship on Chapterhouse. There, Idaho trains young men to go out into the universe and enslave Honored Matres. Duncan also inherits an awkward prescient vision, wherein he sees an old man and woman staring back at him. Duncan restores the memories of the Miles Teg ghola, and escapes in the no ship, evading the trap set for him by the strange couple.

Brian Herbert and Kevin J. Anderson continued from the original series with Hunters of Dune (2006) and Sandworms of Dune (2007), originally planned to be Dune 7 by Frank Herbert. Duncan continues his travels on the no ship, now named the Ithaca by its passengers. He is accompanied by Miles Teg, Sheeana and a group of her Bene Gesserit sisters, the last Tleilaxu Master Scytale, and many others. Duncan and the other refugees from Chapterhouse are still on the run from the Unknown Enemy that hunts them. They don't learn until near the end that the Enemy is the revived empire of thinking machines, and the old couple are actually the computer entity Omnius and the robot Erasmus. In the final confrontation with Omnius, Paul Atreides (brought back as a ghola and with his power of prescience just restored), and then Norma Cenva (the Oracle of Time to the Navigators), both reveal that Duncan is the Ultimate Kwisatz Haderach; not Paul ( who is an "imperfect" Kwisatz Haderach) nor any other Atreides, nor their descendants. Overwhelmed by the unexpected revelations, Duncan decides to unite humanity and the thinking machines—after Cenva permanently removes Omnius from existence—rather than bring about the absolute destruction of intelligent technology for the second time in history. Assuming the responsibility of mediator between the two sides, and with Erasmus' willing participation (the robot being left as the leader and controlling force of the thinking machines), Duncan does something similar to Bene Gesserit Sharing with the robot; possibly along with what seems to be a physical bonding (similar to what Leto II did with the sandtrout) into something of a human machine hybrid. Erasmus then voluntarily "dies", while remaining an Other Memory speaking to Duncan. In addition to being the Final Kwisatz Haderach of the humans, Duncan becomes the new evermind of the thinking machines, guiding their joint future.

According to the Prelude to Dune prequel trilogy (1999–2001) by Brian Herbert and Kevin J. Anderson, Duncan Idaho is born on the planet Giedi Prime, under the Harkonnen Regime. His hatred for the Harkonnens is established when, at eight years of age, his parents are murdered in front of him by Glossu Rabban. Rabban subsequently chooses young Idaho to be the prey for one of his hunts, but Idaho's resourcefulness and the aid of a woman who wants to punish the Harkonnens enables him to escape Giedi Prime for the planet Caladan. Upon arriving at the Atreides palace, he becomes a stableboy at Duke Paulus Atreides' request. After Paulus' death, Idaho expresses his desire to become a Ginaz Swordmaster. In the trilogy's second installment Dune: House Harkonnen, Duncan undergoes the immense rigors needed to be a Swordmaster; he is promoted to the title, alongside a Grumman friend named Hiih Resser, and helps defeat a mob of insurgent students. At the time of Dune: House Corrino, Duncan is an instrumental part of the liberation of the planet Ix from the Sardaukar and Tleilaxu, and even manages to defeat Count Hasimir Fenring in single combat.

In the 1984 film Dune, Duncan is played by Richard Jordan. Everett McGill, who portrays Stilgar in the film, said “I recall Richard Jordan as Duncan Idaho agreed to a smaller presence in Dune for the promise of the breakout character in Dune Messiah and beyond." Though Dune II, a planned sequel film adapting Dune Messiah, was never made, the unfinished script depicts Duncan being revived by Scytale. Emmet Asher Perrin of Tor. com writes that Atterton "plays the mentat ghola reincarnation of Idaho with all the upright stoicism and vulnerability that the character is owed." In the animated television show The Grim Adventures of Billy & Mandy, the 2003–04 season episode "Mandy, the Merciless" parodies God Emperor of Dune, with the character Billy as the repeatedly killed Duncan Idaho. The character is played by Jason Momoa in the 2021 film Dune.
