Apple TV+’s Foundation Just Introduced Its Most Terrifying Villain

Apple TV+ has debuted the official trailer for Foundation season 3, the third installment in its glossy, $200 million reimagining of Isaac Asimov’s science fiction masterwork. The trailers drop early hints of a galaxy on the edge, a galaxy-wide crisis, and a rising force that could be the galaxy’s end: Asimov’s notoriously powerful and charismatic villain, The Mule. The third season of Foundation will release weekly episodes from July 11 to September 12, 2025.

Foundation is a free-wheeling reworking of Asimov’s Foundation novels, the basis for the landmark 1981 film of the same name. The serialized series spans centuries thanks to huge time-skips between seasons. The second season of Foundation concluded with a 138-year time skip, and season 2 focused on a civilization-shaping crisis called the Second Crisis, an averted war between the Foundation and the oppressive Galactic Empire. In between, the Foundation took a much darker turn, weaponizing organized religion to grow its power. The new colony of “Mentalics” was also introduced, a secret society of psionic humans with god-like mental abilities.

Season 3 of Foundation fast-forwards 152 years from the end of the previous season, and places the setting in what Asimov called the Third Crisis. Apple TV+’s official summary says: “Foundation has long since settled into the mainstream, and the once-omnipotent Cleonic Dynasty now shows the first signs of cracking. But both powers are about to face enemies on every front. Enemies from without. Enemies from within. Enemies from across the stars.” These rival forces are forced into an uneasy truce in the face of a third force that could tear them all apart: the Mule.

According to the trailer, the Mule is a fearsome warlord, a man of overwhelming military power, “advanced technology, and a mind controlled with fearsome power.” Gaal Dornick (Lou Llobell), who has taken a steadily more important role through season 2, opens with a dire prediction about the future: “Centuries ago, when we predicted the fall of the galaxy, the Foundation was created to save humanity. But the coming darkness was always the turning point,” the disembodied voice of Hari Seldon (Jared Harris) adds. “We’re out of time,” Gaal responds.

The trailer then shows Mule himself, played by Pilou Asbæk, “turning” enemies into friends. “I can turn enemies into allies,” he says. “Hate into love.” A quick flash to a crowded city in ruins, and the voice of the Mule continues. “It only takes a little nudge.”

The trailer cuts to a litany of explosions, cities crumbling, and battles being fought on an industrial scale. We see the immensity of a dark future, an invasion of solar systems, and entire planets being destroyed. The Mule has the galaxy in his hands.

The third season of Foundation will also see a major shake-up to the cast. In addition to returning cast members like Lee Pace, Cassian Bilton, and Terrence Mann as the three imperial clones Brother Day, Brother Dawn, and Brother Dusk, the main roles include Jared Harris as Hari Seldon, Lou Llobell as Gaal Dornick, and Laura Birn as Eto Demerzel. Also joining the cast are Alexander Siddig as Dr. Ebling Mis, a self-taught psychohistorian and devotee of Hari Seldon’s teachings; Troy Kotsur as Preem Palver, the leader of a planet of psychics; and Cherry Jones as Foundation ambassador Quent. Brandon P. Bell will play Han Pritcher, Synnøve Karlsen plays Bayta Mallow, Cody Fern as Toran Mallow, Tómas Lemarquis as flamboyant entertainer Magnifico Giganticus, Yootha Wong-Loi-Sing as Song, and Leo Bill as Mayor Indbur.

Foundation’s Destiny Still Lies Ahead

The cornerstone of the entire Foundation saga, Asimov’s original story and the series reimagining, is a fictional scientific discipline known as “psychohistory.” Psychohistory is a specialized fusion of sociology and math, the use of computer science to predict the long-term outcomes of large groups of people over many years.

This season, it seems that Foundation is also reaching the limit of even that predictive capacity. As the Mule disrupts populations by bending their emotions and loyalties, human logic itself is out the window. It’s not clear whether the galaxy’s fate is being written by a cosmic game of probability. Instead, it’s looking more and more like a fight for survival.

Visually, the series has upped its game once more. The trailer features sweeping vistas of space, fantastical cityscapes, impressively realized space battles, and epic action set pieces. It’s big-budget TV at its most operatic. But perhaps most powerful, there’s a sense of emotional urgency to the trailer. Can the Empire and the Foundation work together? Can psychohistory hold fast against the Mule’s assault on reason itself? Is there any future where the galaxy doesn’t fall apart?

Season 3 of Foundation seems determined to ask those questions, and to answer them on an even grander scale. Starring a galaxy of familiar and new faces, with weekly episodes dropping beginning on July 11, Apple TV+’s Foundation has already found an audience, but the series may reach new heights with its next installment.

Season 3 of Foundation looks like it will be a final test of whether Seldon’s psychohistorical predictions can survive against threats he did not, and perhaps could not, predict. If the Mule can tear the galaxy apart, can there be any hope of rebuilding? If the Mule is successful, Foundation might also ask a bigger question about Seldon’s legacy: Does a psychohistorical future even still exist if the Mule can so easily manipulate the galaxy’s emotions, reactions, and events?
