Pinto (Chameleon)

A Chameleon took over the identity of Nurse Pinto.

History
"Pinto" assisted in the process that allowed the Chameleons to assume the identities of the humans they abducted. When the Second Doctor exposed her, 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)
