Spencer (Chameleon)

A Chameleon took over the identity of Spencer.

"Spencer" piloted humans to the Chameleon satellite. He was forced to shoot and kill Inspector Gascoigne for getting too close to the truth. He then abducted Polly Wright after she witnessed him kill the Inspector. He later abducted Ben Jackson. He tried to kill the Second Doctor, Jamie McCrimmon and Samantha Briggs with a laser, but failed. After the Doctor defeated the Chameleons, the real Spencer was freed. (TV: The Faceless Ones)
