3. Sharaz Jek
This Phantom of the Opera-inspired supervillain featured in the Fifth Doctor's final story, The Caves of Androzani, and is instantly recognisable thanks to his unusual appearance.
An outlaw specialising in designing androids, Jek used his creations to mine for the rare Spectrox mineral in the planet Androzani Minor's cave systems. Betrayed by his business partner Morgus, Jek was led into one of Androzani's deadly mud explosions in an attempt to take control of the mines.
Surviving the scolding mud, Jek was disfigured and chose to wear a theatrical black and white mask to disguise his horrific burns. He then repurposed his robotic army and cast Morgus' forces out, seizing the mines for himself.
When the Doctor arrived on the planet, Jek became obsessed with his companion Peri Brown. He planned to kidnap her and drug her with the Spectrox to keep her alive and as his obedient prisoner.
War in the caves continued, with Jek's androids battling Morgus' forces. Refusing to cease the fighting or relinquish the Spectrox unless Morgus' head was delivered to him, Jek became bloodthirsty and near-unstoppable. Even as Peri and the Doctor began to die from Spectrox poisoning, his attention was only focused on killing his former partner.
Finally luring Morgus to his lair, Jek forced his enemy into a laser beam and killed him instantly. It wasn't long until Jek was killed himself - cut down by one of Morgus' soldiers.
Free from Jek, Peri lost consciousness from her Spectrox poisoning, and with only one antidote, the Doctor sacrificed himself to save her.
Sinister, theatrical, and ruthless, Sharaz Jek has earned a unique place as one of the most memorable one-off villains, and one who was instrumental in a Doctor's regeneration.
