THE MULE Less is known of "The Mule" than of any character of comparable signifigance to Galactic history. His real name is unknown; his early life mere conjecture. Even the period of his greatest renown is known to us chiefly through the eyes of his antagonists and, principally, through those of a young bride (Bayta Darell)...
The Mule was a powerful mentalic mutant, warlord, and conqueror who posed the greatest threat to the Seldon Plan. His acute telepathic ability to modify the emotions of human beings derailed one of the basic assumptions of Hari Seldon's psychohistory - that, in general, the responses of human populations to given stimuli will remain the same.
The Mule was born on the mentalic planet Gaia within Sayshell Sector, where he was regarded as a criminal. By some means he managed to escape the planet at a young age and use the innate powers of its inhabitants against the Galaxy.
Motivated by awareness of his abnormal appearance and hatred against the galaxy, the Mule used his extensive powers to rise to power and conquer even the First Foundation. The Mule uses his telepathic ability to carve his own empire out of nearby territory, sweeping aside the remnants of the Galactic Empire centered around Neotrantor. The Mule based his rule on the planet Kalgan, which he obtained by mentally converting the warlord of Kalgan. After conquering the First Foundation, he made Kalgan the capital of his Union of Worlds and styled himself First Citizen of the Union. Leading up to, during, and for a good time after the Mule's conquest of the Foundation and its trade confederacy, no one ever actually saw the Mule or knew what he looked like.
Following his conquest of the Foundation, the Mule attempted to locate and destroy the Second Foundation. In the end the First Speaker of the Second Foundation mentally altered him, whereupon he ended his quest and governed as a benevolent dictator until he died a premature death resulting from his mutation.
His name is one he gives to himself, a reference to his genetic sterility. For this reason his empire does not last long after his death.
Physically, The Mule was considered a freak by most people who gazed upon him. His nose was incredibly long, sticking out over three inches from his face. The flesh of the rest of the Mule's face seems stretched across his skull. The Mule's body was spindly and gangly: he weighed only 100 to 120 pounds (45 to 54 kg), stretched out across a 5'8" frame. Thus his joints, such as elbows, seemed to jut out from his diminutive musculature. The Mule's meagerness was glandular and could not be compensated for. Further, the Mule's limbs met at awkward angles, giving the general impression of a scarecrow assembled poorly. It was said that one could not look at the Mule without derision. The only aspect of the Mule which was not blatantly farcical were his eyes, which were described as deep brown and perpetually sad.
The Clown (Magnifico Giganticus)
The Mule disguised himself as the Clown when he met Bayta and Toran Darell. This was his way of taking over the First Foundation. He manipulates the constables and guards into believing he is indeed the escaped 'clown', but at this early stage, neither Toran or Bayta are aware of his psychomanipulative powers.
In the process of negotiations, the Clown/Mule is given a Visi-Sonor, by Ebling Mis with which to amuse himself. He exclaims to Bayta that in his rush to 'flee' the Mule, that he had left his behind. He then offers to play the instrument for Bayta whom he calls "My Lady". In his hands the Visi Sonor not only creates exquisite sounds, but colors, shapes and with the Mule's mental ability, emotion. The Mule disguised as the clown uses his concerts and fame to brain wash everyone.
