Dr Sarker

Dr Sarker was a Nestene/human hybrid that led a plan to convert people into Autons to create an army that could colonise any planet they saw fit.

Character History
Sarker was once an ordinary plastic surgeon that was impoverished but his life altered when he came into contact with a Nestene energy unit which merged with him. As this new life form, he invented the Plastain serum and set up shop on the Vanguard. He soon found himself swarmed by patients, all of which were eventually converted into an army of Autons. He planned on leading them to colonise surrounding planets before being stopped by the Doctor. Sarker melted into a puddle of ooze before slithering through the vents on the Vanguard, maybe destroyed when the hotel blew up.
