Lore & Background

The Mule first appeared in the November and December 1945 issues of Astounding Science Fiction as part of the novella 'The Mule', later published in Foundation and Empire (1952). He is described by Asimov as a 'spindly' creature with 'long, lean limbs and spidery body' that seemed 'thrown together at random.' His mutant ability allows him to sense and manipulate emotions, enabling him to conquer planets bloodlessly. This power made him basically invincible to all opponents and unpredictable to Seldon's plans. He used a Visi-Sonor, a rare multi-keyed musical instrument producing holographic effects, to influence populations on Terminus and Haven. His conquests included converting Foundation intelligence officer Han Pritcher into a loyal agent and compelling scholar Ebling Mis to work himself to death searching for the Second Foundation.

In Their Own Story

In 'The Mule', the figure conquers Kalgan without military force, leaving newlyweds Bayta and Toran Darell to investigate. They escape with Magnifico Giganticus, a court jester described as a 'strange, gangly creature' speaking in 'contorted, vaguely literary language.' The Foundation falls quickly to the Mule's psychic assault. At the Great Library of Trantor, Ebling Mis discovers the location of the Second Foundation but is killed by Bayta Darell just before revealing it, having realized Magnifico is actually the Mule seeking destruction of his only threat. In 'Part I: Search by the Mule' (renamed from 'Now You See It...'), the Mule sends Han Pritcher and Bail Channis on a sixth attempt to find the Second Foundation. Channis, the only 'Unconverted' follower, leads them to Tazenda, which the Mule destroys. After mental torture extracts the true location, the First Speaker reveals that Second Foundation agents have already undone the Conversions on Kalgan and the Foundation worlds. Overwhelmed by despair, the Mule's mind is altered by the First Speaker, forcing him to live out his life as a peaceful despot.

Reader's Guide

The Mule's forces were not a religious order but a military machine built on subjugated wills. His goal was to create an empire where he could rule without opposition, bypassing psychohistory's reliance on mass free will. Key figures included Han Pritcher, converted early on, and Bail Channis, who remained 'Unconverted' until revealing his true allegiance to the Second Foundation. The conflict turned when Channis used a similar psychic ability to free Pritcher from the Mule's control. The resolution involved the First Speaker altering the Mule's mind after the Second Foundation orchestrated an insurrection against his fleet. In adaptations, Wolfe Morris voiced him in 1973 BBC Radio 4; Mikael Persbrandt portrayed him in season two of the 2021 Apple TV+ series as a 'monster of a man, coiled with muscle,' while Pilou Asbæk took over for season three.
