Zereldspidar was a male Snivvian who became a charismatic, although evil, dictator of the Snivvian homeworld, Cadomai Prime. The product of a rare Snivvian genetic defect that resulted in male twin births, Zereldspidar developed a personality disorder which manifested itself in sociopathic behavior. After rising to power on Cadomai, he was eventually ousted by the forces of the Galactic Republic.
