Season 3 Plot
152 years after the events of season two, The Foundation has become increasingly established far beyond its humble beginnings while the Cleonic Dynasty's Empire has dwindled. As both of these galactic powers forge an uneasy alliance, a threat to the entire galaxy appears in the fearsome form of a warlord known as "The Mule," whose sights are set on ruling the universe by use of physical and military force as well as mind control. It’s anyone's guess who will win, who will lose, who will live and who will die as Hari Seldon, Gaal Dornick, the Cleons and Demerzel play a potentially deadly game of intergalactic chess.
Foundation Season 3 aired on July 10th, 2025.
Foundation Season 3 Review
Apple’s ‘Foundation’ Jumps Ahead in Time Again, But Stays A Solid Show. The adaptation of Isaac Asimov’s sprawling science fiction novel series maintains its tightened storytelling and pace while introducing new characters. We are long past the point where Isaac Asimov’s ‘Foundation’ stories are considered “unfilmable” –– the team behind this Apple series have been putting the lie to that since 2021.
Yet, the source material’s endlessly layered and complex themes have not always proven so easy to transition to screens, and the third season of the show continues that. There are storylines and characters who pop (the returning ones), while others struggle to make themselves stand out.
