Cleon, commonly referred to by the metonym Empire, is the name of multiple fictional characters in the 2021 Apple TV+ television series Foundation. They are the Genetic Dynasty of clones who rule the Galactic Empire. In the series, the 12,000-year-old Empire has been ruled for 400 years by a revolving trio of Cleon I clones: Brother Day, a Cleon in his prime; Brother Dusk, a retired and aging Cleon who serves in an advisory role; and Brother Dawn, a young Cleon being trained to succeed Brother Day. The series is an adaptation of the Foundation series of novels by Isaac Asimov, and stars Lee Pace as Day, Terrence Mann as Dusk, and Cassian Bilton as Dawn. Cloning does not factor in Asimov's novels, though emperors named Cleon I and Cleon II appear as supporting characters.
