Pinto

Nurse Pinto was the head of Gatwick Airport's first aid centre in 1966.

Biography
Pinto's identity was taken over by a Chameleon. When the Second Doctor exposed the false Pinto, she tried to kill the false George Meadows for his betrayal, but was killed herself when the armband-like device was removed from the original's arm.

The real Pinto then accompanied the Doctor to the Chameleon satellite. (TV: The Faceless Ones)
