history
He first appeared when The Doctor and Peri were imprisoned by his troopers. Upon meeting the two he took a deep interest in Peri and planned on giving her the chemical he specialized in spectrox which would cure the disease she and the doctor had contracted in order to keep her for himself. Before he could accomplish this however he had to begin a battle between his own forces and androids. Despite losing this battle Jek refused to surrender himself until Morgus was killed and at his feet.

When both Peri and the Doctor were suffering from spectrox poisoning, Jek became agitated by the threat to Peri's life. Subsequently, the Doctor despite in his worsening condition travelled through the caves in order to find a cure, leaving Jek and Peri alone. When the federal army attacked Jek's base, Jek was careless, believing they would never find him and defeat his androids. However Jek's mercenary Stoz decided to join Morgus to try to find Jek's collection of spectrox. Morgus, Stoz and their troops then discovered his hideout only for Jek to brutally attack Morgus revealing his disfigured face before throwing him into a beam killing him. Jek prepared to celebrate his victory before being unexpectedly shot by Stoz, ending his villainy.

Shortly after this The Doctor himself heroically gave his own life in order to save Peri, tragically ending his fifth incarnation but at the same time fulfilling Jek's wish of keeping Peri alive.
