Quillam
From Tardis Wiki, the free Doctor Who reference
Quillam was the technical director and principal divisor of programs on Varos. He was also the controller of everything that happened in the Punishment Dome.
He had a particular interest in experimenting with a transmogrifier, which mutated its victims according to their own unconscious wishes. He had mutilated his own face by experimenting with it and wore a mask which covered one eye.
Quillam subjected Peri Brown and Areta to the transmogrifier, which began mutating them into a bird and a reptile, respectively, but the Sixth Doctor rescued them. He and the Chief Officer were later killed by deadly vines in the Punishment Dome. (TV: Vengeance on Varos)
