Morgus

Morgus was the chairman of the Sirius Conglomerate on Androzani Major and the sworn enemy of Sharaz Jek.

Biography
Morgus wanted money and power and agreed to a business deal with Sharaz Jek. Jek harvested the longevity drug Spectrox on Androzani Minor with his androids. Morgus sold Spectrox to the peoples of Androzani Major at an inflated price. Morgus wanted the profits for himself, however, and betrayed Jek, arranging events so that Jek would be caught in Androzani Minor's mud blasts. Unluckily for Morgus, Jek survived, horribly disfigured.

Not above personally murdering others to achieve his ends, Morgus waged a war on the federal forces, covertly selling weapons to Jek through the mercenary Stotz. He falsely believed that the Fifth Doctor and Peri worked for Jek. When the situation on Androzani Minor got out of hand, Morgus went there where he was betrayed by Timmin, his trusted aid. Timmin became the new chairman of the Sirius Conglomerate on Androzani Major, ousting Morgus by informing the planet's authorities of his numerous crimes. Desperate, Morgus convinced Stotz to help him liberate Jek's Spectrox hoard. Morgus stumbled upon Jek's base and Sharaz forced Morgus' head into an energy beam, killing him.
