Mind Over Matter: The Mule Arrives in Foundation S3

Apple TV+ has released the first official trailer for season 3 of the series, Foundation, the sci-fi epic. Based on Isaac Asimov’s popular series of the same name, the trailer is a big-budget visual feast of collapsing star systems, sprawling space battles, and warring galactic superpowers.

Set to premiere on July 11, 2025, with weekly episode releases continuing to September 12, the third season of Foundation raises the stakes in this already very “big” series. The show, which has always taken some significant liberties with its source material, chronicles centuries of galactic history, bookending that by leaping huge periods at the ends of each season. Season 1 covered just 13 years, with the following time jump of 138 years revealed at the end. Season 2 had an internal time gap of six years and grappled with the Second Crisis, the reveal of Hari Seldon and Gaal Dornick as members of the Second Foundation, an oncoming war between the Foundation and the totalitarian Galactic Empire, and the Foundation’s shocking turn to weaponizing religious cults in its expansion. It also introduced the “Mentalics,” a colony of psionic freaks hidden from the rest of the galaxy.

Season 3, by contrast, reveals that it will leap forward again. The story now takes place 152 years after the end of season 2 and drops the show firmly into what, in Asimov’s stories, is called the Third Crisis. As the official synopsis from Apple TV+ reveals, the Foundation is now a much bigger and more rooted institution than it once was, while the galaxy-spanning Cleonic Dynasty that it once posed such a threat to is now in decline. But the show hints that this institutional rivalry may have to end as these great powers unite in the face of existential threats from both inside and out, and a single foe in particular who can raze whole civilizations with a thought.

“The Foundation’s plans of control were not complete. The Seldon Plan had taken its first wrong turn,” ominously narrates Hari Seldon (Jared Harris) in the trailer, with Gaal Dornick (Lou Llobell) later chipping in with the warning: “We’re out of time.”

The source of that time pressure seems to be the big bad of season 3. Played by Danish actor Pilou Asbæk, he’s a shape-shifting, psionically powerful galactic warlord known as The Mule, and as the trailer shows, he can control, and even change, the way people think. “I can turn enemies into allies. Hate into love,” says the Mule in one shot as he strokes the head of a screaming prisoner. “It only takes a little nudge.”

The trailer is full of big action moments: city-sized space stations explode in events that look like ripples in the fabric of time itself. Planets collapse, space bridges collapse, and star systems collapse. Close-up shots of Asbæk’s Mule show him slowly going insane as he nears absolute power over billions of people.

Lee Pace, Cassian Bilton, and Terrence Mann, who play the three emperor clones known as Brother Day, Brother Dawn, and Brother Dusk, respectively, return. Jared Harris and Lou Llobell also return as Hari Seldon and Gaal Dornick, respectively, and Laura Birn reprises her role as the powerful and enigmatic humanoid robot, Eto Demerzel.

Fear of the Future

Foundation is always, at its heart, a show about Asimov’s ideas around the “psychohistory.” This is a made-up branch of mathematical sociology that aspires to predict the large-scale movements of societies and populations by replacing intuition and common sense with mathematical formulas and statistics. Foundation’s most successful world-building exercise of recent years has been in Asimov’s idea, showing in extreme detail how a galaxy-spanning civilization actually could work.

The trailer suggests an epic, multiverse-spanning visual sense to the show, from the space vistas to rich, realized societies to the sweeping, gladiatorial action sequences. But perhaps most of all, this trailer bristles with emotional tension. The obvious implication of these events is that the two power structures must put aside their differences. The official show description from Apple TV+ echoes that theme with “Could the might of the Empire and the Foundation ever truly unite to face a common threat?” But the real, central question this season seems to be what will become of the idea of psychohistory itself as the ability to predict human thought patterns has been shaken to the very core. Can this branch of theoretical science be saved, or is it doomed by its logic to be made redundant by the Mule’s power to psychically re-engineer human history and society? Is there any version of the future, the trailer asks, where the galaxy isn’t consumed by an endless series of crises?

Season 3 looks to take on all of these questions, and with some genuinely higher stakes, to develop the layered characters and vast world-building further. Beginning with a premiere on July 11, 2025, and weekly releases from there until September 12, the series has plenty of time and a big visual canvas to tell its next chapter of galactic history. If seasons 1 and 2 were about the construction of Seldon’s plans, this season looks like it will be about whether or not that plan can survive the truly unpredictable. The Mule’s arrival may not just herald galactic conflict, but the death of the idea that the future of an entire human civilization can be predicted with any reliability at all.
